Researchers at the Université de Montreal (UdeM) and the Montreal Neurological Institute (MNI), McGill University have discovered that cells which normally support nerve cell (neuron) survival also play an active and major role in the death of neurons in the eye.
SAN FRANCISCO, CA--- Highlights of May's Ophthalmology, the journal of the American Academy of Ophthalmology (Academy), include a new analysis of dietary factors and risks for age-related macular degeneration (AMD), and a landmark study on glaucoma treatment cost-effectiveness as linked to vision improvement and quality of life.
Looking for a better treatment for the autoimmune disease myasthenia gravis, researchers have found that a protein in tick saliva shows promise in limiting the severity of the disease in an animal model in a study published in the Annals of Neurology.
Although scientists know progressive degeneration of retinal ganglion cells and their axons is the primary cause of glaucoma, researchers have yet to identify a way to stop or prevent the degeneration.
In a new study, researchers have demonstrated the significance of central corneal thickness on the clinical management of patients with glaucoma and those suspected to have glaucoma. While confirming previous research about the relevance of CCT in glaucoma management, this study represents one of the first attempts to determine exactly how great an impact CCT has on a patient's intraocular pressure (IOP), fluid build-up inside the eye that is a glaucoma risk factor. Results found that CCT affected more than half of the patients in the study. ''We were astounded to find that so many of the glaucoma patients in our study needed an IOP adjustment, based on their CCT measurement.''

Latinos living in the United States have high rates of eye disease and visual impairment, according to a research study, and a significant number may be unaware of their eye disease. This study, called the Los Angeles Latino Eye Study (LALES), is the largest, most comprehensive epidemiological analysis of visual impairment in Latinos conducted in the U.S.
Highly innovative new drugs that can prevent scarring in the eye after glaucoma surgery have been discovered by a London-based team of scientists, who report today in the journal Nature Biotechnology. By targeting more than one aspect of the scarring process at the same time, the team has been able to use the drugs safely and successfully in animal models of glaucoma surgery.
Eye drops that reduce elevated pressure inside the eye can delay or possibly prevent the onset of glaucoma in African Americans at higher risk for developing the disease, researchers have found. This makes it more important to identify African Americans at higher risk for developing glaucoma so they can receive prompt evaluation for possible medical treatment.
Eye diseases like glaucoma could one day be treated by pharmaceuticals delivered through contact lenses. Chemical engineers from the University of Florida say they've been able to make soft contact lenses containing tiny embedded particles that slowly release drugs directly where they're needed. The research was presented today at the 225th national meeting of the American Chemical Society, the world's largest scientific society, held this week in New Orleans.
While studying mice with a mutant gene whose counterpart causes inherited glaucoma in humans, researchers have discovered a second gene mutation that worsens the structural eye defect that causes this type of glaucoma. The newly discovered gene mutation affects production of L-DOPA. The researchers suggest that it might be feasible to prevent glaucoma by administering L-DOPA, which is used in treating Parkinson's disease.
A new optics technology is providing scientists with real-time microscopic images of the living retina, and may allow doctors to focus in on earlier diagnosis and treatment of diseases such as diabetes and glaucoma. Researchers are using a technology called adaptive optics to peer inside the eyes of human subjects and for the first time get clear, sharp images of features such as blood flow in the eye's retina. Until now, clear images of the living retina were not possible because the eye's own structure interferes with the imaging process.
A major technical advance in astronomy is making it possible for scientists to see individual living cells of the human retina clearly for the first time. This will greatly improve doctors' ability to diagnose diseases of the retina such as glaucoma at an early stage, when intervention and treatment can prevent blindness.
