Dehydrational crisis from severe diarrhoea and risk of age-related cataract

Abstract

A group matched hospital based case-control study of 463 cases and equal number of controls was carried out at Government Medical College and Hospital, Nagpur to evaluate role of severe dehydrational crisis in age-related cataract development. The overall relative risk of age related cataract in relation to dehydrational crisis from severe diarrhoea was estimated to be 3.10 (2.28-4.20). The overall estimates of attributable risk per cent and population attributable risk per cent were calculated to be 0.67 (0.56-0.76) and 0.26 (0.18-0.35) respectively. In conclusion this study identified significant role of dehydrational crisis from severe diarrhoea in cataractogenesis.
