Glaucoma, long held to be a disease primarily of elevated intraocular pressure, in reality may be a disease primarily of neurodegeneration. In an article published online February 18 in Ophthalmology, present a view of glaucoma focused on the degeneration of retinal ganglion cells (RGCs) and their axons in the optic nerve, with an eye toward potential neuroprotective, neuroregenerative, and neur

An investigation into the effects of calcium and iron supplementation on ocular health has found that consuming high amounts of these supplements leads to an elevated risk for the development of normal-tension glaucoma (NTG), according to a study presented here at the American Glaucoma Society 22nd Annual Meeting. w
‘Positive Stress’ Helps Protect Eye from Glaucoma

Working in mice, scientists at Washington University School of Medicine in St. Louis have devised a treatment that prevents the optic nerve injury that occurs in glaucoma, a neurodegenerative disease that is a leading cause of blindness.Researchers increased the resistance of optic nerve cells to damage by repeatedly exposing the mice to low levels of oxygen similar to those found at high altitud
Genes Linked To Common Forms Of Glaucoma
Posted by Bharat (#1) 4438 days ago (Editorial)
Results from the largest genetic study of glaucoma, a leading cause of blindness and vision loss worldwide, showed that two genetic variations are associated with primary open angle glaucoma (POAG), a common form of the disease. The identification of genes responsible for this disease is the first step toward the development of gene-based disease detection and treatment. About 2.2 million people

A technique originally developed to see distant stars now allows researchers to diagnose eye diseases such as age-related macular degeneration months to years sooner than possible with other current methods.The enchanting twinkling of the stars is disheartening to astronomers studying distant galaxies. Distortions in the atmosphere such as turbulence and wind shear create those twinkling effect w
Problem in Transport of Donate Human Retina Led Researchers to Discover New Treatment Path For Eye Disease
Posted by Bharat (#1) 4403 days ago (Editorial)
Sloppy shipping of a donated human retina to an Indiana University researcher studying a leading cause of vision loss has inadvertently helped uncover a previously undetected mechanism causing the disease. The discovery has led researchers to urge review of how millions of dollars are spent investigating the cause of a type of age-related macular degeneration called choroidal neovascularization.
Prevent Blindness America Launches “AMD: Awareness Makes a Difference”
Posted by Bharat (#1) 4397 days ago (Editorial)
Age-related macular degeneration (AMD) is the leading cause of blindness for people over 50 in the Western world. With no known cure, early detection and treatment are keys to saving sight. Prevent Blindness America and its affiliates across the country will once again be offering the “AMD: Awareness Makes a Difference” program. AMD is characterized by loss of central vision, usually in both eyes
Cheaper eye drug may cause vision loss, study says
Posted by Bharat (#1) 4386 days ago (Editorial)
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
