Q\Patients receiving a fluocinolone acetonide intravitreal implant for noninfectious uveitis had a significantly high risk for increased IOP that often necessitated surgical intervention, a study found.
Ocriplasmin (microplasmin, ThromboGenics) injected into the vitreous may be another option for treating symptomatic vitreomacular adhesion and macular holes. One injection of the drug seems to weaken the strength of the vitreomacular adhesion associated with pathologic posterior vitreous detachment (PVD) by targeting the fibronectin, laminin, and collagen fibers that keep the vitreous attached to the macula.
Physical activity may be what the doctor orders to help patients reduce their risk of developing glaucoma. According to a recently published scientific paper, higher levels of physical exercise appear to have a long-term beneficial impact on low ocular perfusion pressure (OPP), an important risk factor for glaucoma.
Older adults with glaucoma are at increased risk of falls resulting in injury, reports a study in the November issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
Patients in the United States who have the cornea-damaging disease keratoconus may soon be able to benefit from a new treatment that is already proving effective in Europe and other parts of the world. The treatment, called collagen crosslinking, improved vision in almost 70 percent of patients treated for keratoconus in a recent three-year clinical trial in Milan, Italy. The treatment is in clinical trials in the United States and is likely to receive FDA approval in 2012. The results of the Milan study are being presented today at the 115th Annual Meeting of the American Academy of Ophthalmology in Orlando, Florida.

These findings might reflect a lack of concerted research in this area. "Not a lot has been known about postoperative IOP in diabetics. Information has been more anecdotal. A number of factors can be involved in IOP. Our study is different, in that we focused exclusively on IOP and diabetes," Dr. Park told Medscape Medical News.
In utero exposure to the organic compound bisphenol A (BPA) -- widely used in the manufacture of plastics, including cups, food containers, and even credit card receipts -- was associated with behavior disruptions at age 3, particularly among girls, researchers found.
"When children older than 8 years go to any ophthalmologist with amblyopia..., they will be told there is nothing that can be done for them; as a result, they will end up being handicapped. When they go to apply to college, they will be rejected, even though they may have brilliant marks," lead author Somen Ghosh, MD, an ophthalmologic surgeon from Kolkata, Bengal, India, told Medscape Medical News. "So I started thinking of some way to help those unfortunate older kids."

In this edition of the journal, Dr. Dominick M. Maino writes in his editorial, The Number of Placebo Controlled, Double Blind, Prospective, and Randomized Strabismus Surgery Outcome Clinical Trials: None!, that the science behind surgical intervention for strabismus may not be as solid as we would like to believe.
RNFL and macular thickness measured with the Cirrus HD OCT was affected by head tilt. Artefacts caused by head tilt should be considered in the analysis of the Cirrus HD OCT measurements.
The vision research community is discussing with the Food and Drug Administration (FDA) how to adopt and/or implement safe and effective endpoint measures for assessing glaucoma therapies in U.S. clinical trials. The group composed of researchers, clinicians, policymakers and representatives from industry and vision associations attended a one-day symposium sponsored by the National Institutes of Health's National Eye Institute (NEI) and the FDA on Sept. 24, 2010.
"We have demonstrated for the first time that you can pay attention through one eye, even when you have no idea where the image is coming from," says Peng Zhang, who conducted the study with University of Minnesota colleagues Yi Jiang and Sheng He. And the harder that eye is working - the heavier the "informational load" - the more effectively still that eye can attend to its object. The findings will appear in an upcoming issue of Psychological Science, a journal published by the Association for Psychological Science.
Women who eat foods rich in a variety of vitamins and minerals may have a lower risk of developing the most common type of cataract that occurs in the United States, according to a report in the June issue of Archives of Ophthalmology, one of the JAMA/Archives journals.
An eye implant that delivers fluocinolone acetonide holds promise for chronic macular edema due to central retinal vein occlusion (CRVO).
Nail bed vascular abnormalities had a significant association with optic disc hemorrhage and other manifestations of glaucoma, data from a Korean clinical series showed.
Purpose: Evaluation of improving near vision in presbyopic patients with low to moderate myopia with selective treatment of high-order aberrations (HOAs) using the ORK-CAM software aberrometer and a SCHWIND ESIRIS excimer laser. In this study, all HOAs except vertical coma were treated and the effect on near visual function was evaluated.
