OBJECTIVE: The present population-based study was undertaken to estimate the prevalence, determinants and causes of corneal morbidity and @entity1939 in a rural North Indian population. DESIGN: Population-based study in India with 12   899 @entity1 of all ages. METHODS: @entity1 were recruited from 25 village clusters of district Gurgaon, Haryana, India using random cluster sampling strategy. All individuals were examined in detail with a portable slit lamp for evidence of any @entity2687 during the door-to-door examination. Comprehensive ocular examination including logMar visual acuity, slit lamp biomicroscopy, non-contact tonometry and dilated retinal evaluation was performed at a central clinic site in the respective villages. RESULTS: Overall, 12   113 of 12   899 @entity1 (93.9% response rate) were examined during the household visits. Prevalence of @entity2687 was 3.7% (95% CI 3.4% to 4.1%) and that of @entity1939 was 0.12% (95% CI 0.05% to 0.17%). Multivariable analysis demonstrated that @entity2687 was significantly higher in the elderly (p<0.0001) and illiterates (p<0.0001). Common causes of @entity5575 in the study population were pterygium (34.5%), @entity2194 (22.3%) and @entity1036 (14.9%). @entity2687 contributing to @entity1939 were @entity2372 (46.2%) and @entity528 (23.1%). CONCLUSIONS: The study findings demonstrate that currently @entity2194 , @entity1036 , @entity2372 , and @entity528 are responsible for the major @entity1939 and morbidity in the Indian population. The prevalence of corneal morbidity due to @entity38569 and @entity11738 was low in this rural population.
