Choroidal Thinning in Pseudoexfoliation Syndrome Detected by Enhanced Depth Imaging Optical Coherence Tomography

Purpose To measure choroidal thickness in patients with pseudoexfoliation (PEX) syndrome and to compare the values with control eyes using enhanced depth imaging optical coherence tomography (EDI-OCT). Methods Thirty-four patients with PEX syndrome and 30 age- and sex-matched healthy subjects were included in this study. Only one eye of each of the patients was included. Choroidal thickness was measured manually from the outer border of the retinal pigment epithelium to the inner scleral border at the subfovea, 3 mm temporal to the fovea, and 3 mm nasal to the fovea using EDI-OCT. Results A total of 34 eyes from 34 consecutive patients with PEX syndrome (19 women and 15 men; mean age 75.3 ± 6.6 years) were included in the analysis. The mean subfoveal, temporal, and nasal choroidal thickness was significantly thinner in the PEX syndrome group compared with the control group (p
