Retinitis pigmentosa is one of several eye conditions that appears to benefit from nutritional substances. In a study published Monday, researchers found that people with the condition experienced a slowing of the disease process if they took vitamin A supplements and ate a diet high in omega-3 fatty acids. Retinitis pigmentosa causes night blindness by adolescence and eventually tunnel vision and total blindness by about age 60. Vitamin A has been a standard therapy for the condition since 1993 when studies showed it slowed disease progression.

Bill Fulton — urban planner, urbane public speaker and mayor of Ventura — was starting to stumble. In dim meeting rooms, he had trouble reading. At the civic events he attended almost nightly, he left some people puzzled — even angered — when they extended their hands and he failed to grasp them. "I can't always see it when someone wants to shake hands with me," he said. "When you're a politician, that's not good. " Fulton, a member of Ventura's City Council since 2003, will step down from office Monday and leave town next spring, largely as an adjustment to an eye disease that is slowly robbing him of his sight.

A small preliminary study has found that valproic acid--a drug already used to treat epileptic seizures, migraines and bipolar disorder--may halt or even reverse the loss of vision produced by retinitis pigmentosa, researchers said Thursday. A team from the University of Massachusetts Medical School in Worchester is now organizing a clinical trial to confirm its observations. Retinitis pigmentosa, commonly known as RP, is a group of eye diseases marked by degeneration of the retina, the part of the eye that captures images, leading to loss of peripheral vision and night vision.

Pennsylvania researchers using gene therapy have made significant improvements in vision in 12 patients with a rare inherited visual defect, a finding that suggests it may be possible to produce similar improvements in a much larger number of patients with retinitis pigmentosa and macular degeneration. The team last year reported success with three adult patients, an achievement that was hailed as a major accomplishment for gene therapy. They have now treated an additional nine patients, including five children, and find that the best results are achieved in the youngest patients, whose defective retinal cells have not had time to die off. The youngest patient, 9-year-old Corey Haas, was considered legally blind before the treatment began.

"Revelation" is the title of a new play by Christina Kokubo. And when it opens next month in Los Angeles, it may well be true to its title. That's because the cast will be made up entirely of blind actors, although the characters are all fully sighted. The play, about a group of people in a mystical land taking shelter during a crisis, was written and is being directed by Kokubo, who began teaching drama at the Braille Institute five years ago.

A widely used heart drug can sharply slow the progression of an inherited form of blindness called retinitis pigmentosa, according to experiments in mice reported today by French researchers. This has the potential to be the first effective treatment of retinitis pigmentosa, commonly called RP, which afflicts as many as 200,000 people in the United States, according to the researchers.
