Congenital & Developmental cataracts occur due to some disturbance in the normal growth of the lens. In congenital cataract the opacity involve embryonic or foetal nucleus & in developmental cataract (occur from infancy to adolescence) opacities involve infantile or adult nucleus,deeper parts of cortex or capsule. Cataract is responsible for about 10% blindness among children in India. This study was performed to survey the causes of childhood cataracts & to identify the preventable factors 1. Etiology : Maternal Infections like TORCH causes cataract in 50% of cases & about one third are idiopathic (33%), one third are hereditary include trisomy 21 (Down’s), Stickler syndrome, Lowes syndrome & malnutrition during pregnancy 1. Material & Methods : It is a six months observational hospital based study . Parents of patients were informed in their native language & informed consent was taken . Results : Out of 30 children, the commonly affected age group was upto 4 years. The most common type of cataract was lamellar. Male to female ratio was 1.5 :1. Bilateral cg. cataract were 70% & unilateral were in 30% cases. 73.1% cases were associated with ocular defects. 20% cases had associated systemic diseases & 23.3% cases had h/o consanguinity . Conclusion : Our study shows that majority of non–traumatic cataracts are due to potentially preventable causes. Health education to women of child bearing age & ophthalmological check up early in life can prevent visual morbidity.
