AIM: To review results of traumatic cataracts in children.METHODS: Only those pediatric patients who fitted in the definite inclusion criteria were considered for study enrollment. They were further examined for any kind of co-morbidities because of trauma, operated upon for traumatic cataracts with intraocular lens implantation. Amblyopia if present was treated. All were re-examined at the culmination of six-week postoperative period.According to the Birmingham Eye Trauma Terminology System the traumatic cataract cases were divided into group 1(open globe) and group 2(closed globe), and then determinants of visual acuity were compared.RESULTS: There were 544 eyes in group 1 and 127 eyes in group 2 in our study of 671 eyes with pediatric traumatic cataracts. Visual acuity at the end of 6 wk after surgery in the operated eye was > 6/60 in 450(82.7%) and ≥ 6/12 in 215(39.4%) eyes in the open globe group and > 20/200 in 127(81.8%) and ≥ 6/12 in 36(28.4%) eyes in the closed globe group(P = 0.143), and the difference between the groups was not significant in children. Overall, 402(39.4%) eyes gained ≥ 6/60 and > 5/12 in 238(35.4%) cases. Surgical treatment caused a significant difference in visual outcome(P = 0.000). When we compared achieved visual outcome with ocular trauma score predicted vision, no significant difference was found.CONCLUSION: Traumatic cataracts in children may have better outcome and ocular trauma score is a useful predictive method for the ocular trauma in children. 展开更多
