Clues to visual variant Alzheimer's; myopia and diabetic retinopathy risk
Date:10/25/2009

SAN FRANCISCO Two studies are of particular note in today's Scientific Program of the 2009 Joint Meeting of the American Academy of Ophthalmology (AAO) and the Pan-American Association of Ophthalmology (PAAO): a report by Swiss neuro-ophthalmic researchers about vision exam clues that should make ophthalmologists suspect an atypical variant of Alzheimer's disease; and new evidence from a Singapore National Eye Center study that diabetics who are nearsighted may be less susceptible to diabetic retinopathy.

The AAO-PAAO meeting is in session October 24 through 27 at the Moscone Center, San Francisco, CA. As the largest, most comprehensive ophthalmic education conference in the world, it offers United States and international Eye M.D.s more than 2,000 scientifically-based, peer-reviewed presentations, including instruction courses, skills transfer labs, "Breakfast with the Experts" roundtables and 900 research papers and posters.

Is it a Visual Problem or Alzheimer's? New Data Helps Doctors Make the Diagnosis

Sometimes when a patient tells his ophthalmologist that he "can't see," what he really means is "I can see, but I can no longer read or write." In a minority of Alzheimer's patients the disease shows up first as problems with vision rather than memory or other cognitive functions. But diagnosis can be difficult because standard eye exams are often inconclusive for these patients. Neuro-ophthalmologists Pierre-Francois Kaeser, MD, and Francois-Xavier Borruat, MD, Jules Gonin Eye Hospital, Switzerland, examined and followed 10 patients with unexplained vision loss who were ultimately diagnosed with the visual variant of Alzheimer's disease (VVAD). Their study describes clinical clues that may improve ophthalmologists' ability to detect VVAD and refer patients for further tests. When patients receive neurological assessment, treatment and family counseling early in the disease, outcomes may be better for all concerned.
