Prevalence of Different Optical Coherence Tomography Findings in a Spanish Cohort With High Myopia

Purpose:To evaluate the prevalence of different optical coherence tomography (OCT) findings in European patients with high myopia.Methods:Cross-sectional study conducted in the Macula Unit of the University and Polytechnic Hospital La Fe (Valencia, Spain). A total of 134 myopic eyes of 69 patients (16 males and 53 females) were included. All patients underwent a spectral domain OCT examination at least once. The presence of tractional and atrophic myopic maculopathy and choroidal neovascularization (CNV) was evaluated through OCT scans.Results:The prevalence of tractional myopic maculopathy was found in 53.7% of the eyes. Within this group, 9.7% had foveal retinoschisis, 23.9% extrafoveal retinoschisis, 31.3% internal limiting membrane rigidity, 24.6% epiretinal membrane, and none had vitreomacular traction. The most prevalent OCT finding was chorioretinal atrophy, present in 79.1% of the eyes. Choroidal neovascularization was present in 61.9% of the eyes. There was a trend toward higher prevalence of CNV...
