Gene silencing may help corneal transplantation
April 15th 2009The side effects of an experimental 'gene-silencing' treatment that is currently being investigated for a variety of diseases could be useful in corneal transplantation, where growth of new blood and lymph vessels is believed to be a major cause of graft failure.
Retina is a multi-layered jigsaw of receptive fields
April 15th 20091.25 million neurons view the world through receptive fields, which operate like a multi-layered jigsaw puzzle. Researchers at the Salk Institute for Biological Studies imply that the nervous system operates with higher precision than previously appreciated, and that apparent irregularities in individual cells may actually be coordinated and more finely tuned.
TGF-beta has essential role in retinal health
April 15th 2009The Schepens Eye Research Institute has found that retinal dysfunction may be caused by blocking the growth factor TGF-beta. The research may have an important impact on the prevention and treatment of diabetic retinopathy and macular degeneration.
Misidentification of retinal stem cells
April 8th 2009Ciliary epithelial cells inside the eye, previously proposed as retinal cell stems, have now been established as being normal adult cells. The misidentification was uncovered by Michael Dyer, PhD and researchers at the St Jude Department of Developmental Neurobiology.
Eye diseases in pre-school children more common than first thought
April 8th 2009In what is believed to be the first comprehensive eye disease study among urban pre-schoolers, investigators writing in the April issue of the journal Ophthalmology report that while vision problems are rare, they are more common than once thought.
