Prevalence and risk factors of pre-senile lens opacities in the 1969-73 Vellore Birth Cohort.

ABSTRACT:

Purpose

To estimate the prevalence and determine predictors of lens opacities (LO) among South Asian Indians aged 41-44 years.

Methods

This cross-sectional study included 1080 participants from the Vellore Birth Cohort, Vellore, South India. All underwent anthropometric measurements, detailed ophthalmic examination including assessment of LO by LOCS III classification and biochemical metabolic measurements. 'Any cataract' was defined as any opacity type with a score of >2 or evidence of cataract surgery in either eye. Data collected included information on ocular history, life-style factors, socio-economic and educational status, cooking fuel and sunlight exposure. Multivariable logistic regression analysis was used to examine the association between risk predictors and LO.<
