Macular Degeneration

Scientists think that new nanoparticles called nanoceria, made out of cerium oxide, are strong antioxidants. So to test the possibility that nanoceria might be used to fight cellular damage from reactive oxygen species (ROS), a team from University of Central Florida treated mice with retinal defects, similar to those in people with age related macular degeneration, and found positive results. The National Science Foundation reports: In a nanocrystalline form, cerium oxide is a powerful an

A protein has been discovered that appears to prolong the live of retinal cells in both healthy and diseased eyes.  Working with mice, researchers hope that this protein discovery may lead to treatments for retinal diseases such as macular degeneration.

To test their hypothesis, the researchers used mice whose eyes have retinal defects similar to those found in patients with age-related macular degeneration. They treated some of the mice with nanoceria and then compared the number of …

The new process has been used in the suppression of new retinal blood vessel growth in mice, a phenomenon called neovascularisation, which is the major sight-threatening symptom associated with age-related macular degeneration in humans …

Promising results for macular degeneration and respiratory syncytial virus infection have been reported in humans, and successful treatments using microRNAs have been achieved in mice. Results of a mouse study showed that delivering …
