In spite of National Programme for Control of Blindness with its control strategies revised from time to time to provide comprehensive health care to the community, blindness and other conditions of ocular morbidity continue to be problems of much Public Health importance. Considering the fact that one-third of India's blind lose their eyesight before the age of 20 years and many of them are under fifteen years when they become blind, early detection and treatment of ocular morbidity among children is important. In Kerala, only some hospital based data are available based on the studies conducted in Regional Institute of Ophthalmology and Medical College Hospitals. Only piece meal data on field based studies are existing. OBJECTIVES 1. To study the prevalence of ocular morbidity among school children of age group 9-15 years. 2. To find the socio demographic factors associated with ocular morbidity in children.
METHODOLOGYAcross sectional study was conducted among a sample of 3130 students of the age group 9-15 years from Government, Private and Aided schools of Perumkadavila Block Panchayat for three months from November 2013. Children were subjected to measurement of height and weight, general examination of the eyes, torch light examination of anterior segment and fundus examination, visual acuity for distant vision and for near vision. Colour blindness was checked using Ishihara's chart. Sociodemographic details were collected using the pretested Performa.
RESULTS28.9% of the study group was having one or more form of ocular morbidity. Majority of the children studied were of 12 years age. Most of the ocular morbidities were either preventable or curable. Among the children having ocular morbidity the leading cause was refractive error (17.9%) followed by Vitamin A deficiency (9.6%), Conjunctivitis (0.9%), Blepharitis (0.3%), Squint (0.1%), Colour blindness (0.1%) and Ptosis (0.01%). The presence of ocular morbidity showed significant association with education, occupation and income of the parent.
CONCLUSIONThe study was useful for detecting preventable and treatable causes of defective vision early in life and thus for minimizing longterm permanent visual disability.
RECOMMENDATIONSThe knowledge about the distribution and socio-demographic association of ocular morbidity would enable in planning of eye care services and to reduce visual impairment. As there is high prevalence of ocular morbidity among school children, it can be suggested that early screening programmes in primary schools can detect a good proportion of visual impairment and other ocular morbidities sufficiently early so that early interventions in such children will help in preventing the progression of the conditions which can lead to blindness.
