Fovista, an experimental drug from private U.S. biotech Ophthotech, showed impressive results when added to Roche's Lucentis (ranibizumab) in a large mid-stage clinical trial.In the Phase IIb clinical trial involving 449 patients with wet age-related macular degeneration (AMD), those receiving Fovista and Lucentis gained a mean of 10.6 letters of vision on a standard reading chart at 24 weeks, ag

A new study suggests that a drug commonly used to treat a type of age-related macular degeneration may in fact increase the risk of severe side effects, including vision loss.The study, led by Dr. Sanjay Sharma, a professor of ophthalmology at Queen's University in Kingston, Ont., found that patients who were treated with the drug Avastin had a 12-fold increase in the risk of developing severe in
A Killer Of Superbugs

Better than antibiotics, it is being used in contact lenses to prevent infections and biomedical products are the next stage. The superbugs have met their match. Conceived at Nanyang Technological University (NTU), it comes in the form of a coating which has a magnetic-like feature that attracts bacteria and kills them without the need for antibiotics. The killer coating, which has been shown to
Diabetes and Eye Problems

Diabetic retinopathy: Nearly one out of three people with diabetes eventually develop retinopathy, damage to the blood vessels in the retina, the lining of tissue at the back of your eye. Most will develop a condition called non-proliferative retinopathy, which doesn't usually threaten their sight. Several studies have shown that you can reduce your risk of severe vision loss from retinopathy an
Bionic eye could help blind to see thanks to camera glasses and a wafer thin chip
Posted by Bharat (#1) 4387 days ago (Editorial)
A retinal implant could one day be used to restore vision lost through injury or disease, after it gave a brief glimpse of light to a group of patients. The device is the creation of Shawn Kelly from Carnegie Mellon University in Pittsburgh, and the result of a decade's worth of research. It is made up of two tiny cameras attached to a pair of glasses which send images to a computer chip attached
Great Study Habits Might Lead to Poor Eyesight
Posted by Bharat (#1) 4387 days ago (Editorial)
Hours of indoor study might help make great students, but might not be good for their eyes. That’s the conclusion reached by research published this month in The Lancet.Scientists looked at students in different areas of the world, comparing rates of myopia (or “nearsightedness.”) The worst eyesight was found in children completing secondary school in large East Asian cities—80-90% of these kids
Human-Eye Precursor Grown from Stem Cell
Posted by Bharat (#1) 4387 days ago (Editorial)
A stem-cell biologist has had an eye-opening success in his latest effort to mimic mammalian organ development in vitro. Yoshiki Sasai of the RIKEN Center for Developmental Biology (CBD) in Kobe, Japan, has grown the precursor of a human eye in the lab. The structure, called an optic cup, is 550 micrometers in diameter and contains multiple layers of retinal cells including photoreceptors. The ac
Topical Aganirsen found to be Active in Retinal Disease
Posted by Bharat (#1) 4393 days ago (Editorial)
Gene Signal, a company focused on developing innovative drugs to manage angiogenesis based conditions, has announced that positive data from a study of aganirsen (GS-101, eye drops) in a nonhuman primate model of choroidal neovascularization has been presented at the 2012 ARVO Annual Meeting in Fort Lauderdale, Florida. Topical administration of aganirsen was found to inhibit neovascular growth a
