Eye health claims made for some supplements are not supported by evidence, and the supplements could pose a risk to the user, researchers say.
“The scary thing is that the [US Food and Drug Administration] doesn’t regulate these supplements for safety or efficacy,” Jennifer J. Yong, MD, told Medscape Medical News.
Dr Yong, a resident at Yale-New Haven Hospital-Waterbury Hospital in Waterbury, Connecticut, and colleagues published a study examining supplement contents online November 20 in Ophthalmology.
Specific Formulas Are Proven
The Age-Related Eye Disease Study (AREDS), a randomized controlled trial published in 2001, showed that a specific formula of nutrients reduced the risk for vision loss from age-related macular degeneration in the intermediate and advanced stages of the disease.
The AREDS formula, made up of high doses of vitamin C, vitamin E, beta-carotene, and zinc, is patented by Bausch and Lomb.
It did not show any benefits in patients with cataracts, (more…)

Investigators randomized 358 children between the ages of 3 and 10 to either observation or patching for 3 hours per day for 5 months, with a 1-month washout period of no patching before the 6-month examination. All subjects were previously untreated for intermittent exotropia, except for refractive correction, with near stereoacuity of 400 seconds of arc or better. Although there was a slightly lower deterioration rate with patching (0.6% vs. 6.1%), the authors conclude both management approaches are reasonable for treating 3- to 10-year-olds.

NEW YORK (Reuters Health) – The nonsteroidal anti-inflammatory eyedrops ketorolac and nepafenac do not prevent cystoid macular edema after phacoemulsification, researchers from Brazil report.
Most patients exhibit inflammation after cataract surgery that requires treatment with an anti-inflammatory eyedrop, typically a steroid, they write in the British Journal of Ophthalmology, online November 10.
Dr. Patrick Frensel Tzelikis from Brasilia Ophthalmologic Hospital in Brasilia and colleagues evaluated the effects of ophthalmic solutions of ketorolac 0.4% and nepafenac 0.1% in preventing cystic macular edema (assessed by optical coherence tomography (OCT)) after phacoemulsification cataract extraction.
Patients were randomly assigned to receive an artificial tear substitute (n=40), ketorolac 0.4% (n=45) or nepafenac 0.1% (n=41). All patients received prednisolone 1% eyedrops on a (more…)

Free iPad App Enables Inexpensive Visual Field Screening
CHICAGO — The free visualFields easy app for the iPad has made it possible to perform visual field screenings in remote areas of the world where access to bulky medical equipment is limited, a new study shows.
“Carrying equipment through mountain passes is very difficult,” explained lead researcher Chris Johnson, PhD, director of the Visual Field Reading Center at the University of Iowa in Iowa City. He said he is pleased that his team appears to have solved the problem. “I was very impressed with how well this screening procedure did,” he said here at the American Academy of Ophthalmology (AAO) 2014 Annual Meeting.
The study was designed to assess the ability of the low-cost program for the iPad to perform visual screening in Nepal.
Testing with the app took an average of 3 minutes and 18 seconds. Researchers compared results (more…)

Vladimir Vladimirovich Putin on Doctors
“Despite all technical innovations in medicine, personal qualities of a doctor have always been most valuable. It goes about attention to people, nobility and execution of professional and moral duty. Our health care system lives owing to such professionals. And we must create all conditions for their decent work,”

CHICAGO — A tapered-release dexamethasone punctum plug appears to be a reasonable alternative to medicated eye drops for patients who have undergone cataract surgery, according to early research.
“In clinical use, the sustained release may reduce patient pain,” said Tom Walters, MD, from Texan Eye in Austin. Dr Walters presented the phase 2 study during the cataracts session here at the American Academy of Ophthalmology 2014 Annual Meeting.
The prospective randomized double-masked trial involved 59 patients at 4 sites. The primary end points of the study were the absence of cells in the anterior chamber — a measure of ocular inflammation — and the absence of pain.
Immediately after cataract surgery, patients were randomized; half received the dexamethasone punctum plug and half received a placebo vehicle punctum plug. In this study, (more…)

Diabetic Eye Screening Clinics, an AIOS Initiative : Dr Q Maskati
The All india Ophthalmological society for the first time in the world organised simultaneously around 150 diabetic
eye screening clinics across the length and breadth of our wonderful country. They have been in progress in the 7 days from 14-20 November, 2014 – tremendous awareness of the need for diabetics to get regular eye check ups has been created. At least 10,000 diabetics have been examined . It has got good media coverage in various parts of the country – this will motivate even more diabetics to seek ophthalmic opinion. I am extremely proud of my 17,000 AIOS members, many of whom participated from small towns like Solapur (250 diabetics screened) and remote places like the Andaman and Nicobar Islands, to name a few! Your president salutes you for creating history! Incidentally Sri lanka is likely to use this model in their own country next year! Long live AIOS!

We report seven cases of successful treatment of acute migraine symptoms using beta blocker eye drops. The literature on beta blockers for acute migraine is reviewed. Oral beta blocker medication is not effective for acute migraine treatment. This is likely due to a relatively slow rate of achieving therapeutic plasma levels when taken orally. Topical beta blocker eye drops achieve therapeutic plasma levels within minutes of ocular administration which may explain their apparent effectiveness in relief of acute migraine symptoms.

This retrospective series analyzed outcomes in 133 patients (139 eyes) implanted with the Boston type 1 keratoprosthesis (KPro), and followed for a mean of 4 years. Before surgery, just 10.8% of eyes were 20/200 or better, after surgery 70% could see 20/200 or better. Although the risk for complications seemed to increase over time, the probability of maintaining useful vision at 7 years was 50%. The cumulative incidence of complications was 49.7% for retroprosthetic membrane formation, 21.6% for glaucoma surgery, 18.6% for retinal detachment, and 15.5% for endophthalmitis.

This retrospective study evaluated the safety of intracameral moxifloxacin 0.5% (500 mg/0.1 ml) in 244 patients (353 eyes) who underwent uncomplicated cataract surgery. At three months postop, there was minimal anterior chamber reaction, and no significant change was noted in corneal thickness or endothelial cell density.
