Scientists discover a molecular 'brake' that helps control eye lens development in zebrafish.
A research team has discovered that abnormal vision in childhood can affect the development of higher-level brain areas responsible for things such as attention.
Research has shown that mistakes in 'proofreading' the genetic code of retinal cells is the cause of a form of inherited blindness, retinitis pigmentosa (RP) with splicing factor defects, which affects up to 2.5 million people worldwide.
Hearing aids and cataract surgery are strongly linked to a slower rate of age-related cognitive decline, according to new research by University of Manchester academics. According to Dr. Piers Dawes and Dr. Asri Maharani, cognitive decline -- which affects memory and thinking skills -- is slowed after patient's hearing and sight are improved.
Biologists grew human retina tissue from scratch to determine how cells that allow people to see in color are made.
For all the good they do, eye drops and ointments have one major drawback: It's hard to tell how much of the medication is actually getting to the eye. Now in a study appearing in ACS Applied Materials & Interfaces, scientists report that they have developed a contact lens that changes color as drugs are released. This visual indicator could help eye doctors and patients readily determine whether these medications are where they should be.
Premature babies with low levels of platelets (thrombocytes) in their blood run a greatly increased risk of being afflicted with a severe variation of retinopathy of prematurity (ROP), an eye disease that can cause blindness, according to a study from Sweden and US published in the journal JCI Insight. In experiments on mice, injections of blood platelets reduce the pathological development of retinal vessels.
Drusen deposits approached the visual center (fovea) of the patient's only functional eye. Use of the National Eye Institute AREDS antioxidant dietary supplement and then two successive statin drugs increased the drusen-free area from ~1500 to ~5000 pixels but were not able to eradicate visual distortions on a home vision test. A weight-loss diet and use of a resveratrol-based dietary supplement (Longevinex®) doubled the drusen-free area from 5074 to 9064 pixels and resolved visual aberrations.
A new study has found compelling evidence that links dynamin-binding protein (DNMBP) to congenital bilateral cataracts and severe vision loss.
By venturing beyond the lab mouse to study the eyes of diurnal small mammals, scientists have uncovered a difference in the composition of rod and cone cell membranes that may explain how a genetic form of macular dystrophy targets only parts of the retina.
