Ocular chemical burns--clinical and demographic profile

Abstract

A clinical and demographic profile of 145 chemical eye injuries in 102 patients treated at a major referral centre of a developing country is analysed. The nature of the chemical agents, the occupation groups at risk and preventive measures for chemical injuries are emphasized. Forty-three patients (42.1 per cent) suffered bilateral injuries. Acids and alkalis together were responsible for 80 per cent of the chemical injuries. Young people working in laboratories and factories constituted two-thirds of the patients. Fifty-two eyes (35.9 per cent) suffered severe (Grade III/IV) injuries. Injuries caused by assault were more severe and proportionately lost more eyes. Visual outcome correlated with severity of injury at initial presentation.
