Correlation between ocular fundus characteristics, diopter and best corrected visual acuity in young patients with high myopia

Abstract

Objective To analyze the correlation between ocular fundus characteristics, diopter and best corrected visual acuity (BCVA) in adolescents with high myopia. Methods The clinical data of 101 adolescent patients (195 eyes) with high myopia who was less than or equal to 18 years old and had diopter greater than -6 D were retrospectively analyzed. The correlation between ocular fundus characteristicss, diopter and BCVA was analyzed. Results There was a positive correlation of diopter with the posterior pole retinal atrophy, tigroid fundus, the paripapillary atrophy β zone, the tilted optic disc (r=0.886, 0.533, 0.544, 0.691; P=0.000, 0.030, 0.028, 0.009). There was a positive correlation of BCVA with the posterior pole retinal atrophy, tigroid fundus, the paripapillary atrophy β zone, the tilted optic disc (r=0.816, 0.041, 0.537, 0.711; P=0.000, 0.483, 0.030). Conclusions Tigroid fundus, posterior pole retinal choroid atrophy, the paripapillary atrophy β zone, tilted optic disc are related to BCVA and diopter in patients with myopia, of which the posterior polar lesion will seriously affect the level of visual acuity in patients.
