Choroidal thickness in normal subjects and in age-related macular degeneration

Abstract

Results of choroidal thickness measurements in 75 healthy subjects of different age groups (123 eyes) are presented as well as those of 35 patients (45 eyes) with age-related macular degeneration. Examinations were performed with a Spectralis optical coherence tomograph using the regimen of Enhanced Depth Imaging (EDI-OCT). A negative dependence between choroidal thickness and age was found (r = -0.78, p < 0.0001). Sub-foveal thickness of the choroid decreases on average by 2.99 µm for every life year. No significant differences in choroidal thickness of age-related macular degeneration patients and that of healthy people of the same age group were found.
