Atlanta (November 20, 2008) – A new study from Georgia Tech shows that when patients with macular degeneration focus on using another part of their retina to compensate for their loss of central vision, their brain seems to compensate by reorganizing its neural connections. Age related macular degeneration is the leading cause of vision loss [Read More]

Drusen Lasering
by Dan Roberts (Updated 11/4/06) Drusen are thought to be fatty waste products from the photoreceptor cells. They often appear on the macula (the center of the retina) in the early stages of Macular Degeneration, and they can cause gradual loss of central vision. “Hard” drusen are common in aging eyes, and do not necessarily [Read More]
Gene Therapy Studies Successful in Slowing Neovascularization
by Dan Roberts January 2002 (Updated February 2006) Researchers at Johns Hopkins’ Wilmer Eye Institute have been able to successfully slow blood vessel growth in laboratory mice in two different experiments involving injection of genes, and human trials have begun. In one study (Mori, K., et al., “Inhibition of Choroidal Neovascularization by Intravenous Injection of [Read More]
New Retinal Vessels Formed From Stem Cells
by Dan Roberts August, 2002 Scientists at The Scripps Research Institute (TSRI) have succeeded in forming new retinal blood vessels in mice with ocular disease. The process uses “pluripotent” adult stem cells, which are derived from bone marrow and injected into the vitreous of the eyeball. When in place, these cells develop into endothelial cells [Read More]
New MD Gene Discovered
by Dan Roberts August, 2002 Researchers at the University of Michigan Kellogg Eye Center have discovered a genetic link to a form of macular degeneration. In an article published in August 2002 in Genome (“X-Linked Recessive Atrophic Macular Degeneration from RPGR Mutation,” pp. 166-171, doi:10.1006/geno.2002.6815, Radha Ayyagari, et al) the gene RPGR (associated until now [Read More]
