Eye ball deviation patterns in traumatic cataract among children in Uttar Pradesh of India

Abstract

Paediatric cataract is an important cause of treatable childhood blindness, provided it is recognized and managed early. Timely diagnosis, management, and visual rehabilitation of a child with a paediatric cataract are crucial determinants of a favourable prognosis. This particular topic, study of pattern of deviation of eye ball after traumatic cataract in children was selected because of the difference between the firm literature of Keith Lyle and the clinical observations. This study includes analysis of 25 patients. The key findings of this study were: Maximum incidence of traumatic cataract was seen in 6-10 years of age group, that too more commonly in boys and it was 2.5 times more than that of girls. lncidence of perforating injuries leading to cataract was 1.5 times more common than blunt trauma. In paediatrics cataract, the Diminution of vision in cases of traumatic cataract is usually at the level of mature or hypermature cataract. 40% of cases showed deviation in the range of 11-20° (irrespective to divergence or convergence). There was higher incidence of Exotropia than esotropia. Originally eye was divergent as per evolution of binocular vision in primates & our study also came out with a conclusion that when there is no force or compulsion of binocular Vision, most of the eyes tended to be Divergent in children after traumatic cataract.
