SECO Announces NEW Dates for SECO 2011

SECO International has announced its official 2011 dates. SECO 2011 will take place March 2-6, 2011 in Atlanta, Georgia. Originally, SECO International published the dates for next years meeting as February 9-13, 2011. But after receiving significant feedback from its survey in February and March that indicated a need to move the meeting to late February or early March, SECO responded immediately and worked with the Georgia World Congress Center to change the dates.

Many attendees and exhibitors shared with us that a March meeting would accommodate their schedules better and ensure greater participation, said Dr. Ron Bannister, president of SECO International. Of course, this years extreme weather also factored into the decision to reschedule the meeting. Everyone agrees that Atlanta in March is typically sunnier, warmer and can be a lot more pleasant.

The 88th SECO International Meeting also will move to Building C of the Georgia World Congress Center in Atlanta. Located on the opposite side of the GWCC, Building C is the newest addition to the facility and opened its doors in 2002. This building offers 420,000 square feet of exhibit space, 29 additional meeting rooms and a large ballroom overlooking a 3.6-acre landscaped plaza

Remembering Dr. John Streff

Comments: My colleagues on the VTOD list shared their remembrances of a great functional optometrist, clinician and teacher: John Streff, OD. DM


This week more than any other, I am acutely aware that every patient interaction I have has been impacted by what I've learned from John. (It's been quite a week!) Every time I pick up a lens or use my retinoscope, the thinking I bring to those moments have been shaped by questions and insights from him. I am especially grateful that I had the chance to know him.


The thing I loved about John Streff was how hard he made me think....I remember coming back from study group spending hours trying to wrap my brain around what he was saying (same with his papers). Once I could wrap my head around these new concepts, it changed how I understood and treated my patients.


Those of us who had the opportunity to learn from him, we know he wanted us to start finding the answers to our own questions, to expand upon what we already had learned (or thought we learned) and to ask new questions. He knew his time left with us was short and wanted to prepare us, to pass the torch so to speak. He was a wonderful person, doctor, teacher and mentor and will be truly missed.


I remember visiting with John Streff at the Gesell Institute for one of my student externships. The first thing he did was give me a minus 3.00 lens to hold six inches from my eye and asked me what I was "seeing." I am still considering his question many years later. He is one of the greatest.


"When you change the way you look at things, the things you look at change."


My first patient this morning was a Streff Syndrome. My patient is poor, being raised by a single dad, who is hoping to keep his job. +0.50s were magic for him and dad saw and understood. I will probably train this child without payment for my services.


Like many, John Streff taught me about near point lenses. It is through us that he continues to change patients lives. The best tribute I think I can give John is to pass forward the goodness he gave me.


Thanks for sharing…, still hard to fathom he's not available to call and pick his brain. We'll remember him for the great person he was. I learned most of what I know about Rx'ing lenses for near from John. I was fortunate to have been in a study group that he was a part of. He had a unique way of treating people he just met like lifelong friends.

A giant has passed from this world to the next.


Amen.

ABO Press Release

American Board of Optometry to Appoint Quality Assurance Team

The profession is reminded that the application process is now open.

ST. LOUIS, Mo., May 12, 2010 The American Board of Optometry (ABO) announced its intention to appoint a quality assurance team to assist in reviewing promotional and educational materials and to ensure the new organization continues to gather input from the profession.

“We have prided ourselves on the collaborative spirit with which the profession took up board certification,” said David Cockrell, O.D., ABO chairman of the Board. “In that spirit, we want to actively engage practicing optometrists to work with the ABO to provide a board certification process that is credible, attainable and defensible.”

“The ABO Board represents a wide cross-section of the profession,” Dr. Cockrell said. “As we begin to roll out the board certification program, we want to have as wide a range of opinions and as broad a base of experience as possible to make the program the best it can be.”

The ABO will be selecting team members in the coming weeks. Among their first assignments will be reviewing existing and proposed promotional materials to ensure they are clear and reflect the profession’s intent.

Since the ABO began accepting applications for board certification on April 30, at www.americanboardofoptometry.org, some have expressed concern that the site initially had promotional statements that could be misconstrued as divisive or were confusing. According to Dr. Cockrell, having the quality assurance team will help the new organization refine its messaging to accurately meet the expectations of the profession.

“We are proud of the work that has been done so far, and of the profession-wide process that has brought us to this point,” Dr. Cockrell said. We will continue to respond to the needs of the profession.”

About the application process

Essential to the ABO board certification process is a completely online application at www.americanboardofoptometry.org that allows candidates to start the process toward becoming an Active Candidate for board certification.

Through the ABO’s partnership with CE City, the application process is as automated as possible, streamlining the primary source verification of the credentials that are required to reach Active Candidate status. Those who are registered will be able to log in to their personal portal to determine when the verification process is complete.

Later this summer, the portal will allow Active Candidates to begin entering information to fulfill the 150-point Post-Graduate Requirements needed for eligibility to take the board certification examination next year.

The launch of the new site and application process is a significant step in the progress of the ABO. The ABO believes that applicants will be pleased with the clean look and feel of the Web site, as well as the simplicity of the application process.

About the American Board Optometry (ABO):

The American Board of Optometry was incorporated on October 14, 2009. The first Board of Directors was appointed by the founding organizations consisting of the American Academy of Optometry, American Optometric Association, American Optometric Student Association and the Association of Schools and Colleges of Optometry.

Children’s reading trouble could be linked to vision problem

Everyone thought Skyla Lutz had a reading problem. She’s in Grade 3 and had been stuck at a kindergarten level of reading for years. Her mother was getting worried about her. But it turned out all that was wrong with Skyla was her vision.

And Waterloo Region school board officials are beginning to see that in 80 per cent of cases where children are struggling with reading, there’s an underlying vision problem.

... Lemon checked Skyla for possible vision problems and sent her to Dr. Patrick Quaid, an optometrist who has a special interest in binocular vision.

After her problem was diagnosed, Skyla was fixed up with a computer game that she plays for half an hour at a time. It requires her to wear 3-D glasses and hit a target. What it really does is strengthen her eye muscles so she can focus better and see the words clearly.

After only four months of the exercises, Skyla’s reading has improved by a whole grade level. “I’m seeing the words better,” she says....

“There are many, many children struggling at school needlessly because of undiagnosed vision issues,” said Quaid, who teaches at University of Waterloo’s optometry school and has a practice in Guelph.

Quaid said if parents know their children are struggling with reading, they should ask the child’s optometrist about their binocular vision status in order to rule out these vision problems. Not every optometrist can treat these issues, but they can refer to a specialist.

It’s also important for parents to take their children to an optometrist before they start school, which is the recommendation of the Canadian Pediatric Association. But only an estimated 14 per cent of students have an eye exam before they start Grade 1.

According to the Ontario Association of Optometrists, children should have their eyes examined at six months old, three years old and then every year, or as recommended.

Warning signs of vision problems in children:

One eye turns in or out

Eyes and eyelids are red, encrusted or tear excessively

Child complains of headache when reading

His or her eyes burn or itch

Words look blurred, seem to move, or there is double vision

Short attention span for reading or writing tasks

Closes or covers one eye while working

Turns head while reading across the page

Blinks excessively at desk work and reading, but not at other tasks

Infants With Cataracts May Derive No Obvious Benefits From IOL Implantation

From AOA First Look:

Infants With Cataracts May Derive No Obvious Benefits From IOL Implantation.
MedPage Today (5/10, Bankhead) reported that, according to a study published online May 10 in the journal Ophthalmology, "infants with cataracts derived no obvious benefits from intraocular lens (IOL) implantation compared with use of contact lenses." In a study of 114 infants ages one to six months with unilateral congenital cataract who were randomized "to primary IOL implantation or to vision correction with contact lenses," researchers found that "median grating visual acuity at one year did not differ significantly between the two types of treatment. Moreover, almost two-thirds of patients in the IOL group required one or more additional intraocular operations, a five-fold increase compared with the patients who received contact lenses."

The Minnesota Optometric Association Advises That Overexposure To UV Rays Can Lead To Eye Diseases

...Children's eyes need protection

"The lenses of children's eyes are more transparent than those of adults, allowing shorter wavelength light to reach the retina," said Dr. Andrist. "Because the effects of solar radiation are cumulative, it's important to develop good protection habits early, such as purchasing proper sunglasses for young children and teenagers." ...

...The Minnesota Optometric Association offers these top five tips to help prevent eye and vision damage from overexposure to UV radiation:

1. Wear protective eyewear any time the eyes are exposed to UV rays, even on cloudy days and during the winter.

2. Look for quality sunglasses or contact lenses that offer good protection. Sunglasses or protective contact lenses should block 99 to 100 percent of UV-A and UV-B radiation and screen out 75 to 90 percent of visible light.

3. Check to make sure sunglass lenses are perfectly matched in color and free of distortions or imperfections.

4. Purchase gray-colored lenses because they reduce light intensity without altering the color of objects to provide the most natural color vision. Brown or amber-colored lenses may be better for those who are visually impaired because they increase contrast as well as reducing light intensity.

5. Don't forget protection for young children and teenagers, who typically spend more time in the sun than adults and are at a greater risk for damage.

US Preterm Birth Rate Declines For Second Straight Year.

From AOA First Look:

US Preterm Birth Rate Declines For Second Straight Year.


ABC World News (5/11, story 8, 00:20, Sawyer) reported that "there's encouraging medical news tonight in the fight against premature births." For the "first time in three decades," the Los Angeles Times (5/11, Maugh) reported, "the rate of premature births in the United States has declined for two years in a row." In fact, according to the National Center for Health Statistics, the "declines were widespread and encompassing, including babies of mothers in all age groups under 40, all ethnicities...and every state except Hawaii."

It's a notable turnaround, considering that "from the early 1980s through 2006, the rate of babies born prematurely, or at less than 37 weeks gestation, rose by more than one-third," USA Today (5/12, Rubin) reports. "Earlier research had suggested several factors behind the rising preterm rate, including increases in preterm labor induction and cesarean sections and a growing proportion of multiple births, which are more likely to be premature." Yet, the "new report found a decline in preterm births for all modes of delivery -- induced and non-induced vaginal deliveries and C-sections."

That means "obstetricians may be putting a halt on early use of those procedures," MedPage Today (5/11, Fiore) reported. "'I think it is very likely that this decrease relates to the widely publicized criticism of delivering babies 'early' for a laundry list of poorly defended indications,' Ian Holzman, MD, chief of newborn medicine at Mount Sinai Medical School ...said in an email." Dr. Holzman, who was not involved in the study, "added that there's likely also better control of multiple gestations via reproductive technology, as multiples have higher preterm rates than singletons."

Overall, "the rate of preterm births has declined, from 12.8 percent of births in 2006 to 12.3 percent in 2008," HealthDay (5/11, Reinberg) reported. Furthermore, "from 2006 to 2008, the rate of preterm births dropped five percent among both blacks and whites," while "the rate of preterm deliveries dropped from 12.3 percent in 2007 to 12.1 percent in 2008," among women of Hispanic descent. "Preterm births also dropped across the country, with 35 states seeing a significant decline."

The declines are considered "amazing" by the medical director of the March of Dimes, because "babies born before 37 weeks...are at increased risk for many serious health problems and disabilities, including cerebral palsy, mental retardation, learning problems, chronic lung disease, as well as vision, heart, and hearing problems," according to the CNN (5/11, Curley) "Paging Dr. Gupta" blog. Still, Dr. Alan R. Fleischman "says more work needs to be done to continue to prevent premature births." So, he is testifying this week "before the House Energy and Commerce Health Subcommittee about preterm birth and infant mortality and he will urge legislators to reauthorize the PREEMIE Act (P.L. 109-450), which supports expanded research, education and other projects to help reduce preterm birth rates."

Reuters (5/12, Fox), the NPR (5/11, Wilson) "Shots" blog, and WebMD (5/11, Hendrick) also covered the story.

3D Vision Syndrome, Eldgergadget.com and Seniors



Comment: I was recently quoted
in Eldergadget.com DM

Samsung: 3DTV Not Inherently Dangerous to Elderly

...We promised you we’d look closer into the 3DTV warning that Samsung issued a few weeks ago. Well, we heard back from the electronics company and talked to an expert on elderly eyes to find out the real deal about seniors and 3DTVs....

...Our eye expert, Dr. Dominick M. Maino, who is editor of the Optometry & Vision Development journal, a member of the American Optometric Association and a professor at Illinois College of Optometry/Illinois Eye Institute, affirms Samsung’s statement.

“Right now, as far as I know, there’s currently no evidence to support the belief that 3D movies harm the eyes – and that includes seniors,” he says.

Dr. Maino does note, however, that senior eyes may not be as good at
[convergence], or moving the eyes toward each other to form a singular picture, as younger viewers are. “The eyes are really only designed to last for 40 years,” he says. “In our late 50s, 60s and older a huge percentage of us have problems getting the eyes to turn in enough to create binocular vision.”...

...All hopes are not lost, however, if you’re unable to see a 3D picture or experience these symptoms when viewing 3DTV. There are many vision remedies out there, although they cannot be obtained without a comprehensive eye exam, which Dr. Maino believes should happen every year if you’re 60 or older.

Dr. Maino has a few other tips for seniors. He recommends watching 3DTV in normal room lighting, creating a comfortable TV-watching environment and, ironically, staying active for optimal 3DTV viewing.

“As research shows, the more active you are the better your brain is,” he says. “And the better your brain works the better your eyes work. Watching a 3D movie for an hour or two would be just fine, but then go do something that’s active for you.”...

TIPS ON HOW TO PROTECT YOURSELF FROM THE SUN

 When possible, avoid sun exposure from 10 a.m. to 4 p.m.
 Apply 1 to 2 ounces of sunscreen depending on size with thorough coverage.
 Apply sunscreen 30 minutes before exposure and reapply every two hours or more often if sweating or coming out of the water.
 Use a broad spectrum sunscreen for UVA and UVB of at least SPF 15 or higher.
 Clothing that has a tight weave and rich in color absorb UV rays the best. The best
clothing has a UPF rating of 50+.
 Wear a broad brimmed hat.
 Avoid tanning beds.
 Protect newborns from the sun.
 Use sunglasses that have 100% UVA and UVB protection that wrap around the sides.
 Never allow yourself to burn.
 Use moisturizers or lotions that have an SPF of 15 for daily use if exposed.
 Use a UV lip block.

Evaluation of the performance of photochromic spectacle lenses in children

...Photochromic lenses can be successfully prescribed for children and adolescents aged 10 to 15 years. Clear and photochromic lenses were considered to be equivalent for indoor activities; however, photochromic lenses were significantly preferred over clear lenses for outdoor activities. Likert grading scales can be used effectively in questionnaires for children and adolescents and further development of questionnaires for use in clinical trials evaluating lens performance in children is warranted.

Children's Sunglasses: Caveat Emptor

...Spectrophotometric measurements were obtained on 40 pairs of children's sunglasses. Some of these sunglasses provide excellent protection from the potentially damaging effects of ultraviolet radiation (UVR), whereas others fail to provide adequate protection for the crystalline lens and retina. Some labels were ambiguous and misleading with respect to whether the sunglass provided adequate absorption of UVR...

....Everyone is at risk for eye damage from the sun year-round. The risk is greatest from about 10 a.m. to 4 p.m. .....
UV radiation in sunlight is commonly divided into UVA and UVB, and your sunglasses should block both forms. ..... Look for a label that specifically states that the glasses offer 99 percent to 100 percent UV protection. You could also ask an eye-care professional to test your sunglasses if you're not sure of their level of UV protection.

Sunglasses should be dark enough to reduce glare, but not dark enough to distort colors and affect the recognition of traffic signals..... Prevent Blindness America, ... recommends lenses that are neutral gray, amber, brown or green. People who wear contact lenses that offer UV protection should still wear sunglasses.

Children also should wear sunglasses. They shouldn't be toy sunglasses, but real sunglasses that indicate the UV-protection level just as with adults. Polycarbonate lenses are generally recommended for children because they are the most shatter-resistant....

The Sun and the Need for Sunglasses


Summer is upon us...so I thought I'd list some studies about the sun and the need for sunglasses. DM

Ultraviolet-B phototoxicity and hypothetical photomelanomagenesis: intraocular and crystalline lens photoprotection.

...Children, adults under 30 years of age, and pseudophakic individuals with UV-transmitting IOLs should wear sunglasses in bright environments because of the UV-B window in their crystalline lenses or IOLs...

Sun exposure and sun protection practices of children and their parents.

...the frequency of sunburn among Irish children suggests we are not providing them with adequate sun protection....

A pilot study of the validity of self-reported ultraviolet radiation exposure and sun protection practices among lifeguards, parents and children.

Encouraging sun safety for children and adolescents.

The rise in the number of cases of skin cancers,... has prompted increased awareness and educational efforts to limit sun exposure. Because 80% of lifetime sun exposure occurs before the age of 18, educating parents and adolescents to incorporate sun-protective behaviors into daily routines is particularly important. ... Educational interventions are recommended that encourage the following: using sunscreen, wearing hats with wide brims and clothing that blocks or absorbs ultraviolet rays, using sunglasses that block ultraviolet radiation, and seeking shade. ...

Blue-blocking IOLs decrease photoreception without providing significant photoprotection.

Violet and blue light are responsible for 45% of scotopic, 67% of melanopsin, 83% of human circadian (melatonin suppression) and 94% of S-cone photoreception in pseudophakic eyes (isoilluminance source). Yellow chromophores in blue-blocking intraocular lenses (IOLs) eliminate between 43 and 57% of violet and blue light between 400 and 500 nm, depending on their dioptric power. ...Yellow IOL chromophores provide no tangible clinical benefits in exchange for the photoreception losses they cause. They fail to decrease disability glare or improve contrast sensitivity. ... the use of blue-blocking IOLs is not evidence-based medicine. ...

No Link Between Childhood Infections, Autism

... Infections during infancy or childhood do not seem to raise the risk of autism, new research finds.

Researchers analyzed birth records for the 1.4 million children born in Denmark between 1980 and 2002, as well as two national registries that keep track of infectious diseases. They compared those records with records of children referred to psychiatric wards and later diagnosed with an autism spectrum disorder. Of those children, almost 7,400 were diagnosed with an autism spectrum disorder.

The study found that children who were admitted to the hospital for an infectious disease, either bacterial or viral, were more likely to receive a diagnosis of autism spectrum disorder.

However, children admitted to the hospital for non-infectious diseases were also more likely to be diagnosed with autism than kids who were never hospitalized, the study found.

And the researchers could point to no particular infection that upped the risk....

Do vaccines cause autism?

New Genetic Clues to Autism Found

... Researchers have discovered two new genes that may be involved with autism, the brain disorder marked by difficulty in communicating and relating to others.

The evidence for one of the two new "susceptibility genes" is stronger than that for the other, says Daniel Notterman, MD, the senior author of the study and a professor of pediatrics, biochemistry, and molecular biology at Penn State College of Medicine in Hershey....

Dr. John W. Streff, of Prescott, Arizona, formerly of Lancaster, Ohio, passed away on May 6, 2010 at the age of 83. He was born in Canby, Minnesota. John served in the Second World War, joining the U.S. Navy V5 Program immediately upon graduation from high school in 1944. He graduated from the Chicago College of Optometry in 1950 for his lifetime profession in behavioral optometry. He left his flourishing private practice in Pipestone,Minnesota, to accept a staff position in 1960 at the Gesell Institute of Child Development (presently Yale University's Gesell Institute of Human Development). John became director of vision research at Gesell. John took a staff position in 1974 as professor of pediatric optometry and vision therapy at the Southern College of Optometry in Memphis. In 1979 John moved to Lancaster to help establish the S.A. NOEI Center (1979-1989), a joint optometric-educational project in conjunction with St. Bernadette Elementary School, and later started a private practice in Lancaster. John retired from clinical practice but continued to lecture internationally and write articles for professional journals. He has been recognized with numerous optometric awards and honors for his work in advancing knowledge of vision development and rehabilitation, as well at treatment of learning related visual problems. He was a leading proponent in advancing the recognition of the importance of ocular-motor function in both vision development and methods of vision therapy treatment. He is also recognized for first publishing an article describing a constellation of visual findings now known as the Streff Syndrome. John authored and co-authored approximately 40 professional papers and books. In 1950, he married Luella Faschingbauer in St. Paul, Minnesota. They raised five sons, Greg, Mark, Dean,Chad and Peter. Luella passed away in 2002. In 2005, John married Marlys Winkels of Prescott, Arizona and moved west. Survivors include his five sons; two brothers, Larry and Al; three sisters, Susan, Pauline and Cathy; wife,Marlys; and her sons, Bob and Jeff; and daughters, Mary, Mona and Anne; survivors also include his grandchildren; and great grandchildren. John lived a great life!

VISION THERAPY AS PERCEPTUAL LEARNING INSIGHTS FROM THE VISION SCIENCES SOCIETY

Comment: An excellent article by Dr. Len Press. Download pdf by clicking on title. DM

Accommodation and the relationship to subjective symptoms with near work for young school children

The aim of this work was to study the relation between subjective symptoms at near and ocularaccommodation in terms of the amplitude of accommodation and the relative accommodation. Asecondary aim was to discuss the diagnosis of accommodative insufficiency. The chosen cohort was examined on two occasions with 1.8 years in between. The first examination included 72 children, 43 boys (mean age 8.1 years, ranging from 5.8 to 9.8) and 29 girls (mean age 8.3 years, ranging from 6.2 to 10.0). The second examination included 59 of these children, 34 boys (mean age 9.9 years, ranging from 7.8 to 11.7) and 25 girls (mean age 10.1 ranging from 8.0 to 11.8). Subjective symptoms at near work headache, asthenopia, floating text, facility problems) were recorded and the amplitude and the relative accommodation, both positive and negative, were measured. The result from the questionnaire showed that at the first examination more than one-third of the children (34.7%) reported at least one subjective symptom when doing near work and 42.4% at the second examination. No symptoms were found among children younger than 7.5 years, but for children between 7.5 and 10 years old at the first examination, the prevalence of at least one symptom was 47.2%. At the second examination, symptoms were reported also for the youngest children, i.e. from the age of 8 years. The discrimination ability for the amplitude of accommodation, both monocular and binocular, was significant. In the first examination the difference between the mean for the two groups (i.e. with and without at least one symptom) was around 2.00 D monocular and 3.00 D binocular. Corresponding figures from the second examination was a difference between the mean for the two groups of around 3.50 D monocular and nearly 4.00 D binocular. We suggest that accommodation measurements should be performed more routinely and regularly, maybe as screening, especially in children over 8 years of age.

ACCOMMODATIVE FACILITY TRAINING

Ophthalmology agrees: Accommodative Facilty can be improved with therapy. DM

The purpose of this paper is to characterize accommodative facility problems and related symptoms among otherwise healthy young pre-presbyopes showing accommodative dysfunction. The purpose is also to evaluate an
accommodative facility training techniqueby studying the effect of the training on relative accommodation.
Subjects and methods
Children aged 9–13 years, referred by School Health Care for near work-related problems and complaining of headaches, blurred vision, asthenopia, loss of concentration, and avoidance of near activity, were selected. Only children with reduced negative relative accommodation (NRA) and positive relative accommodation (PRA) and/or very slow accommodative facility were included. For accommodative facility training, the subjects used an accommodative facility training technique until they reported that the symptoms had disappeared.
Results
In all children, the symptoms gradually decreased and finally disappeared during the training period. Despite some individual variations, our data show a significant increase in both mean NRA and mean PRA among all children characterized with ccommodative infacility due to an impaired relative accommodation.
Discussion
The results indicate that accommodative facility training is an effective method resulting in loss of symptoms and that it also has a real effect on the amplitude of relative accommodation in patients with impaired relative accommodation. Because accommodative infacility may result in asthenopic symptoms, it is of great importance to identify the dysfunction to prevent unnecessary near vision problems.

The Dynamics of Convergence Insufficiency

Many people are hindered by vision dysfunctions. One of the most prominent vergence dysfunctions in society is convergence insufficiency (CI) affecting 7% of the population. This study inspects the dynamics of convergence movements in both CI and normal binocular vergence subjects. Two stimulus types, a four degree and six degree step, were presented to all subjects. The goal was to determine if the dynamics of CI subjects were different compared to subjects with normal binocular vergence. Using the main sequence analysis, data show the dynamics of CI subjects were in the normal range as those who had normal binocular vergence, but were on the lower end. This study shows the dynamics of CI subjects, whom have not had vision therapy, are slower when initiating a convergence movement.

OPTOMETRIC VISION THERAPY IN THE MANAGEMENT OF CONSECUTIVE INTERMITTENT EXOTROPIA ...

Consecutive exotropia refers to a manifest exodeviation following surgery to correct esotropia. Surgery is common for early onset esotropia, particularly congenital/infantile esotropia. Congenital/infantile esotropia is usually accompanied by several ocular phenomena, including: latent nystagmus, dissociated vertical deviation (DVD) and overaction of the extraocular muscles, especially the inferior obliques. Additionally, since there is a disturbance in normal binocular vision, anomalous correspondence (AC) is often present. Despite this poor or limited binocularity, interventions to increase fusional ability are possible and should be considered. We discuss a case of a 12-year-old black female who presented with a moderate angle, consecutive, intermittent, alternating exotropia following bilateral strabismus surgery for congenital/infantile esotropia. Additionally, the patient manifested DVD and AC. Optometric vision therapy, performed in discrete stages, was instituted. It was highly successful in decreasing the frequency and magnitude of the horizontal deviation and in increasing fusional ability despite the presence of a DVD an AC.
