Prevalence of Dome-Shaped Macula and Tilted Disc Syndrome in High Myopia

Abstract

Background and Objective: Dome-shaped macula (DSM) and tilted disc syndrome (TDS) are two macular abnormalities that may occur in eyes with high myopia. The aim of this study was to determine the prevalence of both entities in our population. Patients and Methods: This was a prospective and observational study. Optical coherence tomography of the macula was performed in eyes with high myopia (spherical equivalent [SE] of −8D or greater) to assess the prevalence of DSM and TDS. Results: Sixty-eight eyes were included. Three eyes (4.41%) had DSM and 8 (11.76%) eyes had TDS. The most common macular anomaly was posterior staphyloma (PS) (12 [17.65%]). From the eyes with DSM ( n = 3), only two presented PS. An older age and a higher SE were predisposing factors for PS ( P = 0.003). Conclusions: A lower prevalence of DSM and a higher prevalence of TDS was observed in our population compared to those reported in literature. [ Ophthalmic Surg Lasers Imaging Retina 2023;54:568–572.]
