This study evaluated the ability of Cirrus HD-OCT to accurately measure choroidal thickness and area in normal eyes. Two independent observers used the device to measure choroidal thickness at 500 μm intervals from the fovea in 34 normal eyes. Average subfoveal choroidal thickness was 272 μm. Choroidal thickness measurements showed strong inter-observer correlation but weak correlation with retinal thickness. The study provides baseline data on normal choroidal thickness but had limitations due to its small sample size and unclear visualization of choroidal boundaries in some eyes.
