Does smoking lengthen the photostress recovery test in young adults

1 May 1999

Abstract

Age related macular degeneration (ARMD) is one of the leading causes of severe visual impairment among older Americans. Several hypotheses have been proposed regarding the pathogenesis of ARMD. Studies concerning the relationship between cigarette smoking and ARMD are identified through the use of articles published since 1970. Due to the recently reported correlation found between Age Related Macular Degeneration(ARMD) and smoking we are interested in determining if smoking affects the macula in a young population. The purpose of the study is to determine how quickly the maculae of the young smoking population recover after the Photostress Recovery Test compared to young nonsmokers. The Photostress Recovery Test is a quick, simple and direct procedure used to assess the initial sensitivity loss and the speed of the return of visual function to the macula after a timed exposure to a bright light stimulus. If a correlation between smoking and the health of the macula is found it could lead to increased awareness and prevention of macular defects in later stages of life.
