Background and objective: To evaluate choroidal thickness using spectral-domain optical coherence tomography (SD-OCT) in patients with obstructive sleep apnea syndrome (OSAS) in comparison to healthy controls.
Patients and methods: This observational, comparative study consisted of 35 patients with OSAS and 32 age- and sex-matched controls. The controls did not have systemic or ocular diseases. All study participants underwent complete ophthalmic examination as well as choroidal thickness measurement using a high-speed, high-resolution SD-OCT device.
Results: The mean horizontal and vertical choroidal thicknesses, respectively, were 237.84 ± 69.9 μm and 234.97 ± 62.0 μm (P = .654) in patients with OSAS and 244.09 ± 41.2 μm and 241.88 ± 40.9 μm (P = .590) in the healthy controls. The mean choroidal thicknesses were thinner in patients with OSAS, but the difference was not significant (P > .05 for all values).
Conclusion: No differences in choroidal thickness were found between patients with OSAS and healthy controls.
