Prevalence and associated health and lifestyle factors of myopic maculopathy in northern China: the Kailuan eye study

Abstract

Background To evaluate the prevalence and associated health and lifestyle factors of myopic maculopathy (MM) in a northern Chinese industrial city. Methods The cross-sectional Kailuan Eye Study included subjects who participated in the longitudinal Kailuan Study in 2016. Ophthalmologic and general examinations were performed on all the participants. MM was graded based on fundus photographs using the International Photographic Classification and Grading System. The prevalence of MM was evaluated. Univariate and multiple logistic regression were adopted to evaluated risk factors of MM. Results The study included 8330 participants with gradable fundus photographs for MM and ocular biometry data. The prevalence of MM was 1.11% (93/8330; 95% confidence interval [CI] 0.89–1.33%). Diffuse chorioretinal atrophy, patchy chorioretinal atrophy, macular atrophy, and plus lesions were observed in 72 (0.9%), 15 (0.2%), 6 (0.007%), and 32 eyes (0.4%), respectively. MM was more common in eyes with longer axial length (OR 4.517; 95%CI 3.273 to 6.235) and in participants with hypertension (OR 3.460; 95%CI 1.152 to 10.391), and older age (OR 1.084; 95%CI 1.036 to 1.134). Conclusions The MM was present in 1.11% of the northern Chinese individuals 21 years or older and the associate factors include longer axial length, older age, and hypertension.

Absolute Risks and Decision Tools for Communicating the Risks of Visual Impairment From Myopia-Related Diseases

“…Fourteen papers reporting the prevalence of MMD were identified in the literature review. 7 , 27 , 28 , 33 – 43 Nine papers were excluded due to absent or insufficient information on myopia severity, 33 – 36 , 38 , 39 , 43 disease prevalence, 41 or VI prevalence. 40 Two papers were excluded as the participants did not meet the correct age criteria.…”
