METHODS: The fundus of 1449 patients (2879 eyes) with myopia were retrospectively examined. The clinical relationship between myopic retinopathy and diopter, age, and sex was analyzed. RESULTS: Myopic retinopathy was detected in 413 eyes (14.35%). Posterior pole retinal lesions were detected in 22 eyes (0.76%). Peripheral retinal lesions were found in 396 eyes (13.75%). According to their diopters, the myopic patients were divided into four groups: low, medium, high and super high myopia The incidence of peripheral retinal lesions was 4.18%, 8.72%, 19.18%, and 37.44% in these four groups, which significantly different (chi2 = 178.594, P<0.001). By age these patients were divided into three groups: I group, age <25; II group, age 25-34; III group, age >34. The incidences of peripheral retinal lesions in these three groups were 8.11%, 15.34%, and 24.59%, which were significantly different (chi2 = 76.090, P<0.001). The incidence of retinal lesion in male and female was 9.32% and 16.07%, respectively, which was significantly different (chi2 = 24.886, P<0.001). Posteriorpole retinal lesions were only detected in the highly or super highly myopic patients, all of them were more than 25 years. The incidence of posteriorpole retinal lesions in the highly and super highly myopia group was 0.86% and 6.67% respectively, which was significantly different (chi2 = 31.898, P<0.001). The incidence of posteriorpole retinal lesions in group II and group III was 0.55% and 3.55% respectively, which was significantly different (chi2 = 22.523, P<0.001). CONCLUSIONS: The prevalence of retinal lesions in myopic patients is higher than that of emmetropia. The incidence of peripheral retinal lesions increases in patients with deeper diopters. Posterior pole retinal lesions usually occur in the myopic patients whose age are more than 25 years and diopter more than - 6.00 D. Careful examination of fundus is essential for early detection and timely treatment.
