ABSTRACT
PURPOSE:
Childhood blepharoptosis may cause cosmetic and functional problems in children, but there is a paucity of studies about its epidemiology. This study aimed to investigate the prevalence of childhood blepharoptosis and associated risk factors in a representative Korean population.METHODS:
This cross-sectional nation-wide study analysed the data set acquired from the Korea National Health and Nutrition Examination Survey 2008-2012. A total of 8218 children aged 3-18 years were included. The prevalence of childhood blepharoptosis, defined as a margin reflex distance (MRD) of < 2 mm in either eye, was estimated, and the risk factors were identified using multivariate logistic regression analysis.RESULTS:
The mean age of participants was 11.3 ± 0.1 years, and 52.8 ± 0.6% were boys. The overall prevalence of childhood blepharoptosis in Korea was 8.0% (95% CI, 6.9-9.1%). Boys exhibited a higher prevalence of blepharoptosis than girls at most of ages. Levator function increased with age in the normal general population. The proportion of subjects exhibiting MRD1 ≥ 4.0 mm also increased significantly with age (p < 0.001). Male gender, higher body mass index, and urban residency were significantly associated with childhood blepharoptosis.CONCLUSIONS:
The prevalence of childhood blepharoptosis is higher in urban obese boys. The increase of levator function with age should be considered in evaluations of childhood ptosis.
