Age-related macular degeneration treated with a stem cell retinal patch

Researchers developed retinal eye patch made from human embryonic stem cells to treat age-related macular degeneration. Researchers grew retinal pigment epithelial cells from stem cells and used synthetic basement membrane to create a retinal patch. Phase 1 clinical trial findings are reported in the journal Nature Biotechnology.Age-related macular degeneration is the most common cause of visual impairment in the … Continue reading Age-related macular degeneration treated with a stem cell retinal patch

New biomarkers to predict the success of diabetic macular edema treatment

Researchers have found new biomarkers that predict prognosis following current treatments for diabetic macular edema. The research was led by Dr. Rajeev Muni, a vitreoretinal surgeon at St. Michael's Hospital. The study is published in the journal JAMA Ophthalmology.Diabetic macular edema is one the common complication of Diabetes. It is associated with the accumulation of fluid in the macula, … Continue reading New biomarkers to predict the success of diabetic macular edema treatment

Artificial retina using synthetic and biological materials

A synthetic, soft tissue retina made of hydrogels and biological cell membrane proteins was developed by an Oxford University student Vanessa Restrepo-Schild. Research involved combining biological and synthetic tissues in a laboratory. Designed like a camera, the aqueous droplets containing bacteriorhodopsin (bR), a light-driven proton pump act as pixels, detecting and reacting to light to … Continue reading Artificial retina using synthetic and biological materials

Association between cataracts and depression identified in elderly population

Older adults with cataracts are more likely to have symptoms of depression, reports a study in Optometry and Vision Science, the official journal of the American Academy of Optometry. The link between cataracts and depression is independent of other factors, and appears strongest among older adults with lower education, according to new research by Haifang Wang, … Continue reading Association between cataracts and depression identified in elderly population

Zika virus infection can cause Glaucoma in infants

A team of researchers in Brazil and at the Yale School of Public Health has published the first report demonstrating that the Zika virus can cause glaucoma in infants who were exposed to the virus during gestation.Cross-section of Zika virus, with capsid layer (pink), membrane layer (purple), and RNA genome (yellow)Credit: Wikipedia, David GoodwillExposure to … Continue reading Zika virus infection can cause Glaucoma in infants

Researchers map Genetic mutations behind X-linked Retinoschisis, a type of macular degeneration

Two gene mutations that trigger a retinal disease that causes blindness in one in 5,000 males have been mapped, leading to the potential for new therapeutic treatments.  Researchers from The University of Manchester undertook a structural analysis of X-linked Retinoschisis (XLRS), a genetic disease leading to a type of macular degeneration in which the inner … Continue reading Researchers map Genetic mutations behind X-linked Retinoschisis, a type of macular degeneration
