Poor Night Vision May Predict Age Related Macular Degeneration

Researchers say poor night vision may predict AMD.


HealthDay (11/13, McKeever) reported that, according to a study published in the Nov. issue of the journal Ophthalmology, "poor night vision might be a predictor of age-related macular degeneration (AMD)." Researchers from the University of Pennsylvania School of Medicine gave "more than 1,000 people with early signs of AMD" a questionnaire in which respondents were asked to "rate their difficulties with night driving and low-light activities," then tracked the participants "for up to six years." The authors found those "with the worst night vision at the start were most likely to develop reduced visual acuity and one of two types of advanced AMD -- geographic atrophy (GA) or choroidal neovascularization (CNV)."
