COVD Call for Posters

COVD is soliciting abstracts for papers and posters to be presented at the COVD 39th Annual Meeting. Any person wishing to make a presentation is invited to submit a proposal.

All abstracts will be reviewed by the Research Committee and will be judged on the basis of overall quality, completion of required information, relevance to behavioral and functional vision, subject matter, innovation, and attention to key questions in the field. Proposals may include research results, case studies, or new and innovative diagnostic procedures or treatment techniques. S

ubmission deadline for abstracts is June 15, 2009

Comment from Pat Wyman

Comments: Pat frequently follows this blog and appreciates the ongoing discussion and information concerning vaccines that I post here. (see below). I am a very strong believer that overall and for most children, vaccination is a must. If you do not vaccinate your child....you put them at risk...and many others as well. Diseases that used to kill our children will come back with a vengence.

Now having said that....it should be fairly obvious to most that the current recommended vaccination schedule appears to be insane! I would suggest that you talk to your pediatrician about how that schedule may be modified for your family and the possible consequences if it is modified.

We are utlimately responsible for the well being of our children....if we do not have them vaccinated...we could be responsible for the disabiltiy and even death of others offspring as well. DM

Dear Dr. Maino,

As a regular reader of your blog, I appreciate the information on the new study about vaccinations.As a mom, I did vaccinate my kids, but today, after reading so much research on all sides of the issue, have so many unanswered questions about whether I'd do it again.I've seen movies of healthy kids who suddenly weren't healthy after vaccinations. This is such a big controversy, I hope to see more on the subject from you.

An examination of binocular reading fixations based on sentence corpus data

Binocular eye movements of normal adult readers were examined as they read single sentences. Analyses of horizontal and vertical fixation disparities indicated that the most prevalent type of disparate fixation is crossed (i.e., the left eye is located further to the right than the right eye) while the left eye frequently fixates somewhat above the right eye. The
Gaussian distribution of the binocular fixation point peaked 2.6 cm in front of the plane of text, reflecting the prevalence of horizontally crossed fixations. Fixation disparity accumulates during the course of successive saccades and fixations within a line of text, but only to an extent that does not compromise single binocular vision. In reading, the version and vergence system interact in a way that is qualitatively similar to what has been observed in simple nonreading tasks. Finally, results presented here render it unlikely that vergence movements in reading aim at realigning the eyes at a given saccade target word.

Dr. Allen Cohen to lecture

Clinical Application of Neuro-Optometric Diagnostic &Treatment Procedures For: Patients With Balance & Dizziness Patients With Visual Field Loss

August 15th & 16th

Presented by: Allen H. Cohen, O.D., F.A.A.O., F.C.O.V.D.

San Jose, CA – May 29, 2009: The Optometric Extension Program Foundation will sponsor a critical Regional Clinical Seminar about Acquired Brain Injury which is scheduled for August 15th & 16th, 2009. Our presenter will be Dr. Allen H. Cohen, retired Chief of Optometry Services for the Northport VA Medical Center, and Professor of Clinical Optometry at State University of New York.

Dr. Cohen has been in private practice for over 40 years and has specialized in visual rehabilitation following acquired brain injury for over 25 years. He maintains a private practice in Lake Ronkonkoma, New York. Acquired Brain Injury (ABI) is a term that encompasses traumatic brain injury (TBI), and cerebral vascular accident (CVA). During this comprehensive two-day seminar, Dr. Cohen will discuss:
· Concepts for diagnosis and management of the dizzy patient
· Concepts for diagnosis and management of patients with visual field loss
· Review of principles for high yield neuro-optometric rehabilitation therapy
· Developing treatment procedures for neuro-optometric rehabilitation therapy for patients with ABI, the dizzy patient and patients with visual field loss

This event will be held at the Palo Alto VA Medical Center Auditorium, and provides12 hours of continuing education, of which 2 are COPE CE hours.. This event requires pre-registration and is open for optometric vision professionals (optometrists and vision therapists). For registration information, please contact: The Optometric Extension Program Foundation at (949) 250-8070. If you have questions regarding the seminar or wish to volunteer to assist, please contact Thomas Headline at (408) 528-9509.


...Unvaccinated children are 23 times more likely to get whooping cough compared to fully immunized children, according to a new study.
The study, which was funded by the National Institute of Allergy and Infectious Disease, was the first to use electronic health records to examine the link between parents' refusal of vaccines for their children and possible pertussis infections. Pertussis, commonly known as whopping cough, is a highly contagious bacterial disease that causes uncontrollable, violent coughing and can be fatal in infants, especially those under two months of age who are too young to be vaccinated....

Visual Acuity Norms in Pre-School Children: The Multi-Ethnic Pediatric Eye Disease Study.

VA test performance in normal pre-school children improves with age. We propose new age-specific thresholds for defining abnormal monocular VA using HOTV optotypes in children between 2 and 5 years of age, for use in screening, clinical practice, and research.

Effect of Amblyopia on the Developmental Eye Movement Test in Children.

The performance of amblyopic children on the DEM, a commonly used clinical measure of eye movements, has not previously been reported. Under habitual binocular viewing conditions, amblyopia has no effect on DEM outcome scores despite significant impairment of binocular vision and decreased VA in both the better and worse eye.
