Abstract

Purpose: To analyze the behavioral, morphometric & accommodative risk factors for myopia progression. Methods: Cross-sectional observational study of 56 myopic children, aged 5 – 18 yrs, divided into two groups: Gr1: Progression (at least 0.5 Dsph increase from previous in at least one eye by cyclopentolate refraction) and Gr 2: No progression. A questionnaire regarding parental myopia, education, outdoor activities, smartphone usage, and usual distance at near work, was administered. The Axial length/ Corneal radius ratio (AL/CR) (IOL master 700) and Accommodative lag (ACCL) (Monocular Estimation Method) were measured in each eye. These were compared between the two groups. Results: Neither lifestyle factors nor AL/CR showed a significant difference between Gr 1 and Gr 2. There was a significantly higher ACCL (1.8 ± 0.49) among those who progressed compared to those who did not(1.5±0.56) (p<0.05). Conclusion: Higher Accommodative lag is associated with myopia progression.
