Myopia is one of the first causes of visual impairment worldwide. The aim of this study is to describe the prevalence of retinal complications related to myopia and high mypoia in a multicentric cohort of individuals.
This cross-sectional analysis was carried out in eye clinics dedicated to refractive errors. Data collection included age, gender, refractivesubjective error on both eyes and any relevant ocular history. Four different groups of individuals with Mild Myopia (-0.5 to -2.75D),Moderate Myopia (-3 to -5.75 D) and High Myopia (-6 to -7.75D and less than -10D) were analyzed. Spherical equivalent of the right eye was exclusively analyzed. Retinal complications mainly included staphyloma, lacker cracks, myopic choroidal neovascularization and chorioretinal atrophy.
Data files from 537 573 individuals (54.7% of women) were analyzed. The mean age was 38 years old (SD: 17.5 years).Overall prevalence of myopia was 37.3% (95% CI 37.2-37.4%).Prevalences of mild, moderate, high and very high myopia were respectively 24.6%, 9.7%, 2.5% and 0.5%. Prevalences of staphyloma were of 0.5% and 3.6% in the high and very high myopia groups. Prevalences of other macular complications related to myopia will be presented during the congress.
This large cohort provides new insights in terms of prevalences of retinal complications related to myopia regarding to the degree of myopia. These results confirm the importance of myopia as a major health issue in Western countries.
This is an abstract that was submitted for the 2017 ARVO Annual Meeting, held in Baltimore, MD, May 7-11, 2017.
