Abstract Details


The aim of the study was to investigate peripapillary choroidal thickness (PPCT) in patients with Obstructive Sleep Apnea Syndrome using spectral-domain optical coherence tomography (SD-OCT).


This study was performed in the Department of Ophthalmology, Kanuni Sultan Suleyman Education and Research Hospital and Chest Diseases and Sleep centre, Istanbul Mehmet Akif Ersoy Thoracic and Cardiovascular Surgery Training and Research Hospital, Istanbul, Turkey.


This prospective study included 60 eyes of 60 patients. OSAS groups according to their apnea hypopnea index (AHI) values. The PPCT was measured by SD-OCT using enhanced depth imaging (EDI) modality. Temporal and nasal PPCT was analyzed using 1-way Anova test.


There were 30 eyes in the control group, and 30 eyes in the OSAS group. There was no difference between OSAS and control groups with respect to age, gender, IOP, axial length, refractive values, and existence of systemic diseases including diabetes and hypertension. PPCT measurements are shown in Table. No significant differences were found between the groups (all, p>0.05). The PPCT measurements were not correlated with the AHI (p>0.05 for all).


This study showed that both temporal and nasal PPCT did not differ significantly between the groups.
