Human stem cell models reveal neurodegeneration in glaucoma   Glaucoma, a serious eye condition responsible for causing vision loss, affects over three million Americans.

Researchers question the mechanism of retinitis pigmentosa   Researchers who made a knock-in mouse-model of the genetic disorder retinitis pigmentosa 59, or RP59, expected to see retinal degeneration and retinal thinning. As reported in the journal Cells, they surprisingly found none, calling into question the commonly accepted -- though never proved -- mechanism for RP59.         Oxidative stress and growth factors associated with development of high myopia   According to the first world report on vision published by the WHO in 2019, a third of the planet's population suffers from myopia, and around 400 million people suffer the most harmful version of the disease: high myopia.

Researchers develop artificial liquid retinal prosthesis to counteract the effects of eye disorders   Researchers at IIT-Istituto Italiano di Tecnologia (Italian Institute of Technology) has led to the revolutionary development of an artificial liquid retinal prosthesis to counteract the effects of diseases such as retinitis pigmentosa and age-related macular degeneration that cause the progressive degeneration of photoreceptors of the retina, resulting in blindness.       New eye drops could prevent vision loss after retinal vein occlusion   Researchers at Columbia University Irving Medical Center have developed eye drops that could prevent vision loss after retinal vein occlusion, a major cause of blindness for millions of adults worldwide.       Exercise can slow or prevent macular degeneration   Exercise can slow or prevent the development of macular degeneration and may benefit other common causes of vision loss, such as glaucoma and diabetic retinopathy, new research suggests.
