The epidemiology and disease pattern of pediatric ocular morbidities in Western India: The National Institute of OphthalMology AmBlyopia StUdy in Indian Paediatric EyeS (NIMBUS) study report 1

PURPOSE: To determine the pattern of pediatric ocular morbidities in western India. METHODS: This was a retrospective longitudinal study that included all consecutive children aged £15 years who presented to the outpatient department of a tertiary eye center for the first time. Patient demographics, best-corrected visual acuity (BCVA), and ocular examination data were compiled. Subgroup analysis was also performed based on age group (years): £5, 5–10, and >10–15. RESULTS: A total of 11,126 eyes of 5563 children were included in the study. The mean age of the study population was 5.15 (±3.32) years with males (57.07%) being predominant. Approximately half of the patients (50.19%) were under the age of 5 years, followed by those aged 5–10 years (45.1%) and >10–15 years (4.71%). Among the study eyes, the BCVA was ³20/60 in 58.57%, indeterminable in 35.16%, and <20/60 in 6.71%. The commonest ocular morbidity noted was refractive error (28.97%) followed by allergic conjunctivitis (7.64%) and strabismus (4.95%) in the total study cohort and also after age stratification. CONCLUSION: Refractive error, allergic conjunctivitis, and strabismus are the major causes of ocular morbidity in pediatric eyes at a tertiary care center. Planning screening programs at the regional and national levels is crucial to decreasing the burden of eye disorders. These programs also need to have a suitable referral mechanism established and be smoothly connected to primary and secondary health-care centers. This will help to assure quality eye care delivery, while also reducing the strain of overworked tertiary centers.
