by Dan Roberts September 2003 Japanese researchers have found that mutations in the RDH5 gene can cause macular dystrophy, fundus albipunctatus, and/or night blindness. Twenty-one patients from nineteen different families with fundus albipunctatus were analyzed. Ten of the patients had macular dystrophy. In eighteen, mutations were found in the RDH5. The patients were tested using [Read More]

Accutane May Inhibit Progression of Stargardt's Disease
by Dan Roberts April 2003 Accutane, a prescription drug used to treat acne, has been shown to inhibit the development of lipofuscin deposits in the retinas of rodent models. This is promising news for people with Stargardt’s disease. The author of the study is Dr. Gabriel Travis, professor of ophthalmology and biological chemistry at the [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]
Carbon Dioxide May Improve Vision in AMD Patients
by Dan Roberts April 2002 AMD patients are benefitting from a new combination drug therapy being tested at the University of Texas Health Science Center at San Antonio (UTHSC). The therapy involves a combination of medicines which includes carbon dioxide, an element which dilates the blood vessels in the retina for the maintenance of proper [Read More]
Cells From The Iris May Replace Retinal Photoreceptors
by Dan Roberts November 2001 An online publication of the December 2001 publication of Nature Neuroscience has reported that, with genetic manipulation, cells from the iris may be able to replace photoreceptor cells in the retina. In recent experiments, Dr. Masatoshi Haruta of Kyoto University and colleagues took iris cells from rat eyes, then introduced [Read More]
