Population of neutrophils in body found by researchers

Population of neutrophils in body found by researchers

Case Western Reserve University researchers have discovered a novel population of neutrophils, which are the body’s infection control workhorses. These cells have an enhanced microbial killing ability and are thereby better able to control infection. Continue reading

Drivers with hemianopia fail to detect pedestrians, study shows

Drivers with hemianopia fail to detect pedestrians, study shows

A diagnosis of hemianopia, or blindness in one half of the visual field in both eyes as the result of strokes, tumors or trauma often means the end of driving. In about half of the states in the United States and in many other countries, driving with hemianopia is prohibited. However, in some countries including Belgium, the Netherlands, the UK, Switzerland and Canada, driving with hemianopia is permitted after passing a specialized road test Continue reading

Altering eye cells may one day restore vision

Altering eye cells may one day restore vision

Jan. 25, 2013 — Doctors may one day treat some forms of blindness by altering the genetic program of the light-sensing cells of the eye, according to scientists at Washington University School of Medicine in St. Louis. Continue reading

Light shed on complexity of gene therapy for congenital blindness

Light shed on complexity of gene therapy for congenital blindness

Jan. 21, 2013 — Independent clinical trials, including one conducted at the Scheie Eye Institute at the Perelman School of Medicine, have reported safety and efficacy for Leber congenital amaurosis (LCA), a congenital form of blindness caused by mutations in a gene (RPE65) required for recycling vitamin A in the retina. Inherited retinal degenerative diseases were previously considered untreatable and incurable Continue reading

Scientists discover genes responsible for cornea blindness

Scientists discover genes responsible for cornea blindness

Jan. 15, 2013 — Scientists at Singapore Eye Research Institute and A*STAR’s Genome Institute of Singapore have succeeded in identifying genes for central corneal thickness that may cause potentially blinding eye conditions. Continue reading

Light exposure during pregnancy key to normal eye development

Light exposure during pregnancy key to normal eye development

Jan. 16, 2013 — New research in Nature concludes the eye — which depends on light to see — also needs light to develop normally during pregnancy. Scientists say the unexpected finding offers a new basic understanding of fetal eye development and ocular diseases caused by vascular disorders — in particular one called retinopathy of prematurity that can blind premature infants.

Treating eye diseases with anti-VEGF therapies may have side effects

Treating eye diseases with anti-VEGF therapies may have side effects

Jan. 11, 2013 — A new Investigative Ophthalmology & Visual Science (IOVS) article reveals that increasingly aggressive therapies that block VEGF could cause damage in treating eye diseases Continue reading

Young scientist helps identify cause of widespread eye disease

Young scientist helps identify cause of widespread eye disease

Dec. 21, 2012 — Branch retinal vein occlusion — blockage of the blood vessels that channel blood from the retina — is a common eye disease. A type of blood clot in the eye, the disease causes reduced vision, and people with the disease also typically have an increased risk of hypertension, diabetes and other serious conditions.

Fear of falling may cause social isolation in older adults with vision problems

Fear of falling may cause social isolation in older adults with vision problems

Dec. 11, 2012 — A new study published in Investigative Ophthalmology & Visual Science found that between 40 to 50 percent of older adults with visually impairing eye disease limit their activities due to a fear of falling Continue reading
