Dry eye disease in children and adolescents in India

Abstract

Purpose: To describe the etiological causes and clinical profile of dry eye disease (DED) among children and adolescents seeking eye care in India.

Methods: This was a cross-sectional study of 1023 new patients (≤21 years of age) diagnosed with DED presenting between 2010 and 2018 to a multi-tier ophthalmology hospital network. Children and adolescents with both symptoms and signs of dry eyes were considered as subjects. The data entry and retrieval were done using an electronic medical record system and analyzed using appropriate statistical tests.

Results: The mean age of the patients was 15.2 ± 5.6 years and 76% were in their early and late adolescence. Overall, the main etiologies responsible for DED in children and adolescents were Meibomian gland dysfunction (MGD) in 49% of cases, Stevens-Johnson Syndrome (SJS) in 33% and Vitamin A deficiency (VAD) in 9%. Aqueous deficiency dry eye (ADDE) because of SJS and VAD accounted for most of the cases in infancy (92%), toddlerhood (96%), early childhood (76%) and middle childhood (68%). While Meibomian gland dysfunction (MGD) related evaporative dry eye (EDE) was the leading cause of DED in early (51%) and late adolescence (66%). Severe visual impairment and blindness was significantly greater in eyes with ADDE as compared to those with EDE (p < 0.0001), 81% of which were affected by SJS.

Conclusion: The causes of and visual morbidity due to DED varied significantly in different age-groups. Most of the visual morbidity in children and adolescents was limited to eyes with ADDE due to SJS.
