Potential new biomarkers may aid early detection of glaucoma

Researchers at Ruhr-Universität Bochum have identified new potential biomarkers that may facilitate early detection of glaucoma in patients. Moreover, they ascertained that the mutation of a certain gene in mice causes intraocular pressure elevation.

			New form of therapy may stop or reverse progressive vision loss A new form of therapy may halt or even reverse a form of progressive vision loss that, until now, has inevitably led to blindness.

			Common diabetes medication may protect against age-related macular degeneration Researchers from Taiwan have shown that people with type 2 diabetes who took a common diabetes medication, metformin, had a significantly lower rate of age-related macular degeneration.

	UCV researchers discover the influence of exosomes on age-related macular degeneration Researchers of the Neurobiology and Neurophysiology team of the Medicine Faculty at Valencia Catholic University, headed by Jorge Bacia, have discovered that exosomes - microscopic extracellular vesicles that are released by all cells - from the retinal pigment epithelium lead to cases of neovascularization, a finding which could be closely related to similar processes in age-related macular degeneration.

	Computer games and a summer birthday linked to increased risk of myopia in childhood According to a new study by researchers in King's School of Life Course Sciences, time spent playing computer games and being born in the summer are both linked to an increased risk of developing short or near sightedness (myopia) in childhood.

	Common glaucoma tests can underestimate severity of the condition The most common tests for glaucoma can underestimate the severity of the condition by not detecting the presence of central vision loss, according to a new Columbia University study.

	Purdue researchers invent new smart drainage device to help glaucoma patients Purdue University researchers have invented a new smart drainage device to help patients with glaucoma, a leading cause of blindness in the world, as they try to save their eyesight.

	Seeking ways to prevent 'secondary cataracts' Today's cataract surgery is often described as a marvel of modern medicine, a one-hour outpatient procedure that has spared millions from blindness, especially in developed countries.

	Chronic dry eye can slow reading rate and disrupt day to day tasks Johns Hopkins researchers report that chronic dry eye, a condition in which natural tears fail to adequately lubricate the eyes, can slow reading rate and significantly disrupt day to day tasks that require visual concentration for long periods of time.

	Optic Neuritis and Multiple Sclerosis Optic neuritis (ON) is characterized by inflammation of the optic nerve with acute loss of vision in one eye. It is among the initial manifestations of multiple sclerosis (MS) and occurs secondary to demyelination. Most reported cases are associated with MS; however, it may occur in isolation.

	Novel approach could provide painless, efficient alternative for treating eye diseases Nanyang Technological University, Singapore scientists have developed a 'contact lens' patch with microneedles that could provide a painless and efficient alternative to current methods of treating eye diseases such as glaucoma and macular degeneration.

	Vision impairments may increase risk of falls in older adults Vision impairment and blindness affect one in 11 Americans age 65 and older. Because our population is aging, the number of older adults with vision problems is predicted to rise.
