Six years ago Daphne Bavelier at the University of Rochester, New York, exploded the myth that gaming is bad for your eyes by showing that expert gamers outperform non-gamers at a variety of visual tasks (New Scientist, 31 May 2003, p 11). Now she has demonstrated that playing action-packed video games improves a person's ability to perceive contrast, a skill we rely on in dark conditions....

Rewiring My Old Brain
By Susan R. Barry, Ph.D. on April 1, 2009 - 1:46pm in Eyes on the Brain
Imagine that you are a professor of neurobiology who, for the past seventeen years, has been lecturing to your students on the conventional wisdom about the brain. Then, quite unexpectedly, you discover through your own experiences, that the conventional wisdom is not so wise. This is exactly what happened to me....
The contents of your medicine cabinet may not be what they seem.
Just 10 of the 21 multivitamins tested met the quality claims on the label, ConsumerLab.com of White Plains, N.Y., reported in January. Several had significantly more or less of the active ingredients than promised; one was contaminated with lead....Last fall, more than 1 million counterfeit OneTouch diabetes test strips flooded the United States and went on sale in 700 pharmacies in 35 states.
Walgreens is extending a helping hand to unemployed, uninsured workers and their families, offering to treat minor aches and pains for free at its Take Care clinics in 342 locations in some 30 metro areas. But there's a catch: To be eligible, workers or their family members have to have visited a Take Care clinic in the past.
Comments: There's always a catch! DM
Comments: It's notable that so many studies are looking at drugs for a cure...when some of the most "drug resistant" folks around seem to be those who are parents of a child with autism. It will be interesting to see how the Autism Street reacts to all these new meds? It may be worthwhile for the researchers to spend some research dollars on how to get parents to understand and accept the use of drugs as treatment for autism...DM
Comments: A long time ago when I was just an optometric puppy, I was talking to an individual who was very motorically impaired. He had a "sip & suck" system that allowed him to move his wheel chair and to communicate. I guess may lame attempt at being empathetic (I was still young and inexperienced but learning quickly) was crossing over to the "pity" side ...when he mentioned that we all are TABs....or Temporaily Abled Bodied. .... and that I will experience my TAB existence soon enough....well, I'm old enough now to have experienced some TABness ....and one of the things I've noticed is that my empathy side has gotten much better....my understanding of disability has gotten much better and my patient care (although I hope it was always good) has gotten much better! We are all TABs. Remember this the next time you see a patient with a disability. DM
Comments: It seems as if this particular drug is being given out like candy. It is being used not only for seizures, but for migraines, behavorial issues, and even to promote neuroplasticity. It can cause a myopic crisis and narrow angle GLC. Now that a generic is available ... watch for a significant increase in its use. The prescriber of this med should conduct a blood test to monitor the level of a patient's serum bicarbonate.
Many of my patients with intellectual disability and mental illness are on this medication (along with a bunch of others....watch for the May issue of the AOA's Optometry journal for an article on polypharmacy and special populations by Robert Donati and me). So far I may have had one patient who may have had eye problems associate with this drug....so you don't see these eye problems often...but we should be aware of both the system and oculo-visual side effects. DM
Comments: I've been recommending Omega-3s more an more for my patients since I started using them mostly for my dry eye. As the research continues to poor forth...Omega-3s may be one of those "wonder" foods we've been looking for. As always...consult your doc before any major changes in diet, diet supplements, or medications...DM

Ocular movement (basic examination) File size: 2.8MB Unless told otherwise begin with a cover and alternate cover test for near and distant fixation. Examine the eye in the nine cardinal positions of gaze. Do not forget to perform horizontal and vertical saccades. Special thanks to Miss D. Louis FRACO for the demonstration.
Prism cover test (right esotropia) File size: 3.4MB This is a common request in part II OSE. Before carrying out the test, perform the cover/uncover test and alternate test to ascertain if the patient has eso- or exo- tropia or phoria. The prism cover test is carried out with the apex pointing in the direction of the tropia or phoria. Performed the prism cover tests for near (using a fixation target) and distant. The end point of the test occurs when there is no eye movement on alternate cover test. This patient has a right esotropia.
Abnormal cover/uncover tests File size: 3.4MB Three patients with abnormal cover/uncover tests. First patient had had surgery for infantile esotropia which recurs. The second patient has consecutive exotropia following surgery for esotropia; cover test shows latent nystagmus. The third patient has a left sixth nerve palsy, however; cover/uncover test in the primary shows a right esotropia because the patient is fixating with her left eye.
Fourth nerve palsy File size: 3.3MB Fourth nerve palsy may present as cover/uncover test or ocular motility examination. The patient in this video has a right fourth nerve palsy and had had previous right eye surgery. In the primary position, the eyes are orthophoric but not so on lateral gaze and head tilt.
Aberrant third nerve regeneration File size: 1.7MB This patient who had had a left third nerve palsy following road traffic accident develops aberrant regeneration resulting in eyelid elevation during downgaze and adduction.
Chronic progressive external ophthalmoplegia File size: 2.7MB Two patients with chronic progressive external ophthalmoplegia showing bilateral ptosis and symmetrial ophthalmoplegia.
Möbius's syndrome 608KB ( The patient has expressionless face and is unable to blow her cheeks or frown. There is poor eyelid closure despite lateral tarsal strips and medial canthoplasties in both eyes. The horizontal eye movement is restricted as shown by the need of the patient to move her head in order to follow the finger. Vertical eye movement is normal. There is also wasting of the tongue muscles.)
Möbius's syndrome and Poland's anomaly 640KB ( The patient has features similar to video 2. In addition, she has micrognathia and Poland's anomaly which consists of congenital distal limb abnormalities with syndactylism and amputation).
Congenital exotropia 570KB ( The patient has congenital exotropia with visual acuities of 6/60 in the right eye and 6/6 in the left. She had has two previous operation to correct the right exotropia. Cover tests show bilateral latent nystagmus worse in the right eye. The left eye also shows DVD - dissociated vertical deviation. Ocular motility reveals A-pattern exotropia and right superior oblique underaction.)
Partial third nerve palsy 722KB ( This patient developed a sudden onset right ptosis and diplopia. The pupil was spared. The third nerve palsy was attributed to her diabetes mellitus).
Third nerve palsy1,427KB(This patient who suffers from diabetes mellitus and hypertension develops a sudden onset right ptosis. Examination reveals that the right eye has limited movement in those muscles supplied by the third nerve. The pupil is not involved. The appearance is that of a medical thrid nerve palsy.)
Left fourth nerve palsy 880 KB(This young girl has a abnormal head posture. The cover/uncover tests are normal with the head tilted. But with the head in the primary position, there is a left over right. Ocular motility shows left inferior oblique overaction and poor depression of the left eye in adduction.)

Submitting Manuscripts to Biomedical Journals: Common Errors and Helpful Solutions
Journal of Manipulative and Physiological TherapeuticsVolume 32, Issue 1, Pages 1-12 (January 2009)
This article reviews common, but avoidable, errors that authors may make when submitting to a health care–focused, biomedical journal (eg, chiropractic, medicine, nursing, and physical therapy). As editors, we offer suggestions for improving the quality of manuscripts submitted to biomedical journals, provide suggestions for how to avoid making errors, and recommend effective writing and submission strategies. Common errors in the following sections are discussed: title, abstract, key words, introduction, methods, results, discussion, conclusion, acknowledgments, references, tables, figures, cover letter, format and writing, submission processes, communication with the editor, revision processes, and proof processes. This article includes a checklist that authors may use before submission and that peer reviewers may use for general critique of a manuscript. The goal of this article is to assist authors with successful manuscript submission and eventual publication.
These guys really rock, jam and more! DM
