Abstract Details


To invastigate the choroidal thickness using optical coherence tomography in the eyes of patients with unilateral and bilateral pseudoexfoliation syndrome and to compare them with healthy controls.


Baskent University Hospital, Department of Ophthalmology, Ankara, Turkey


We studied four groups: (1) affected eyes from 20 patients with unilateral PEX syndrome affecting the right eye of 11 patients and the left eye of 9 patients; (2) unaffected eyes of 20 patients with unilateral PEX syndrome; (3) the eyes of 20 patients with bilateral PEX syndrome; and (4) the eyes of 20 normal healthy subjects.Choroidal thickness was evaluated using high-speed, high-resolution enhanced depht imaging by spectral-domain optical coherence tomography. Optical coherence tomography features were compared in all groups using the statistical package SPSS v 15.0.


The mean subfoveal choroidal thicknesses were 237.35  58.01 µm in group 1; 330.75  47.84 µm in group 2; 206.3±86.75µm in group 3; and 311.8±51.42µm in group 4. Significant differences in the mean subfoveal choroidal thickness were found between groups 1 and 2 (P<0.001), groups 1 and 4 (P=0.004), groups 2 and 3 (P<0.001), and groups 3 and 4 (P<0.001).


In this study, it was observed that clinically affected eyes of patients with PEX syndrome have significantly thinner choroids compared with the clinically unaffected eyes of patients with unilateral PEX syndrome and eyes of healthy controls.
