A minimally invasive treatment for retinal detachment gives patients sharper vision, less distortion and reduced side-effects, according to the findings of a randomized controlled trial performed at St. Michael’s Hospital in Toronto. The findings have been published in Ophthalmology, the journal of the American Academy of Ophthalmology. “The most commonly offered treatment for a retinal […]Continue Reading ...
Nov 1 2018 Sheets of fetal cells integrate into the retina and generate nearly normal visual activity in the brains of blind rats, reports new research published in JNeurosci. Degeneration of the retina as a result of age or progressive eye disease damages the light-detecting cells necessary for accurate vision. Current treatments can only help […]Continue Reading ...
Scientists at the UCLA Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research and the Stein Eye Institute have been awarded a $5.1 million grant from the California Institute for Regenerative Medicine to advance the development of a novel therapy for blinding retinal conditions. The award by the California Institute for Regenerative […]Continue Reading ...
Proliferative Vitreoretinopathy and Giant Retinal Tears Proliferative vitreoretinopathy (PVR) is a condition in which retinal scar tissue, or “membranes” form; this may occur with a retinal detachment. A key risk factor for developing PVR is a giant retinal tear—a large tear that involves at least 25% of the retina. When PVR or a giant retinal […]Continue Reading ...
August 16, 2018 Study Could Lead to Cures for Blinding Diseases Researchers at Mount Sinai have successfully restored vision in mice through activating retinal stem cells, something that has never been done before. Their study, published in the August 15 online issue of Nature, could transform treatment for patients with retinal degenerative diseases, which currently […]Continue Reading ...

(HealthDay)—Survivors of Ebola virus disease (EVD) have localized pathological changes in photoreceptors, according to a study published online May 3 in JAMA Ophthalmology. Paul J. Steptoe, M.B.Ch.B., from the University of Liverpool in the United Kingdom, and colleagues conducted a prospective case series study to describe the appearance of EVD retinal lesions. Ophthalmological images were […]Continue Reading ...
Nov 22 2018 “Exactly one year ago, we spoke about the fact that, in future, it will be possible to diagnose diabetes from the eye using automatic digital retinal screening, without the assistance of an ophthalmologist – 12 months on, MedUni Vienna is right in the middle of this digital revolution.” These were the words […]Continue Reading ...
IUPUI biologists are growing ‘mini retinas’ in the lab from stem cells to mimic the growth of the human retina. The researchers hope to use the research to restore sight when critical connections between the eye and the brain are damaged. These models also allow the researchers to better understand how cells in the retina […]Continue Reading ...
Researchers have grown human retinal cells in the laboratories and thus attempted to understand the basis of color vision and its development in humans. The results showed that certain hormones are essential for the development of color vision in humans and were published in the latest issue of the journal Science. Researchers at the Johns […]Continue Reading ...
By Sally Robertson, BScAugust 20, 2018 Scientists have developed an ultrathin artificial retina that could provide a superior alternative to the visual implants currently available to the blind. Image Credit: Africa Studio / Shutterstock It is hoped that the device, which will be described today at the 256th National Meeting & Exposition of the American […]Continue Reading ...
August 8, 2018 Blue light from digital devices and the sun transforms vital molecules in the eye’s retina into cell killers, according to optical chemistry research at The University of Toledo. The process outlined in the study, which was recently published in the journal Scientific Reports, leads to age-related macular degeneration, a leading cause of […]Continue Reading ...

Credit: Dong-Ho Park, M.D., Connor Lab A research team at Massachusetts Eye and Ear has shown that microglia, the primary immune cells of the brain and retina, play a protective role in response to retinal detachment. Retinal detachment and subsequent degeneration of the retina can lead to progressive […]Continue Reading ...
June 19, 2018 A research team at Massachusetts Eye and Ear has shown that microglia, the primary immune cells of the brain and retina, play a protective role in response to retinal detachment. Retinal detachment and subsequent degeneration of the retina can lead to progressive visual decline due to photoreceptor cell death, the major light-sensing […]Continue Reading ...
