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.
