Abstract
Purpose To study the pupillary light reflex in patients with choroidal neovascularization due to age-related macular degeneration (AMD). Methods The study included 15 patients with AMD and 15 control subjects. A full recording of the pupil's reaction to light was registered and the following eight parameters were measured and reported: baseline pupil radius (R1), latency (T1), minimum pupil radius (R2), amplitude (AMP), maximum constriction velocity (VCmax), maximum constriction acceleration (AC-max), time for maximum velocity (T2), and time for maximum constriction (T3). Results All variables measured presented alterations in the AMD group and a number of them were significantly reduced in the AMD group. Conclusions The presence of neovascular AMD significantly affects the pupil's response to light stimulus when compared to normal subjects.
