Optical Coherence Tomography Angiography Findings in Polycystic Ovary Syndrome.

Abstract

To evaluate microstructure and vascularity of macula and optic disc in polycystic ovary syndrome (PCOS) by optical coherence tomography (OCT) and OCT angiography (OCTA). Descriptive study. Department of Ophthalmology and Department of Obstetrics and Gynecology, University of Health Sciences, Yüksek lhtisas Training and Research Hospital, Bursa, Turkey between January and June 2019. Fifty-nine patients with PCOS and 35 healthy controls were enrolled in the study. Foveal avascular zone (FAZ), the capillary density assessed in the superficial capillary plexus (SCP) and deep capillary plexus (DCP) in the macula and was also measured in optic disc using the OCTA. The thicknesses of the retinal nerve fiber (RNFL), ganglion cell complex (GCC), and macula were measured by OCT. The capillary density in the macula and optic disc region were not a significant difference between the PCOS patients and healthy controls.The parafoveal superior, inferior, and temporal quadrant thickness was significantly higher in the study group compared to control group (p=0.047, p=0.033,and p=0.033, respectively). In patients with PCOS, there were negative correlations between IR and inferior RNFL, total and superior GCC thickness (r=-0.29 p= 0.027, r=-0.27 p=0.050, r=-0.31 p=0.029, respectively). Although no microvascular macular abnormalities were seen in PCOS patients, the parafoveal thickness significantly increased in all quadrants, except the nasal quadrant. In patients with PCOS, IR, dyslipidemia may affect the structural integrity of the retina. Further longitudinal follow-up studies are needed to determine whether PCOS has any effect on OCTA findings.
