Abstract


AIM : To describe the epidemiologic trends and risk factors for chemical injuries of the eye.

METHODS: This cross-sectional observational study was done among 84 patients of chemical ocular injury by different substances between June 2018 - June 2019. Clinical history was taken and clinical examination was done to elicit findings related to eye injury and its complication After initial evaluation patients were also followed up for next 3 months to evaluate the visual outcome

RESULTS: Male : female ratio affected with chemical ocular injury was found to be 2.3:1. Most common age group to be affected was 26-40 years. Males between 26-35years and 46-55 years and females of 36-45 were affected most.  60  (72%) cases had ocular burn due to alkali and remainder was acid burn. Among alkali, hydrated lime Ca (OH)2  had highest percentage 84.6%. The whole eyeball was affected in 3 patients. Only corneal involvement was seen in 42 patients. Patients presenting with only chemical conjunctivitis was 12. Corneoscleral involvement was seen rest of the cases. 47.6 % of the study population had grade I severity with 28.5% having grade 2 severity.

CONCLUSION : Ocular chemical burns is a major ocular problem at workplaces  and the risk to young adults is substantially higher. Protective glasses at workplace can aid in reducing the hazards leading to ocular injury. Early institution of management is essential to prevent sight threatening visual complications.
