Choroidal thickness decreases with age, greater axial length

Subfoveal choroidal thickness decreased significantly with age and increased axial length in a group of healthy eyes, according to a study.Investigators evaluated 155 subjects with a mean age of 53.5 years (range: 22 years to 89 years). Enhanced-depth imaging OCT was performed with the Cirrus (Carl Zeiss Meditec) and Spectralis (Heidelberg Engineering) systems to measure choroidal thickness from the outer limit of the retinal pigment epithelium to the inner surface of the sclera.
