Scoring system helps to predict outcome of pediatric traumatic cataract surgery

The Ocular Trauma Score proved reliable in predicting final visual outcomes in subjects with pediatric traumatic cataract, a study found.

“In our study, final visual outcomes were achieved according to the OTS prediction in children with traumatic cataract,” the study authors said. “Although others report similar findings, our study presents one of the largest reported databases of pediatric traumatic cataracts classified according to [the Birmingham Eye Trauma Terminology System]. Despite the long delay between injury and treatment in many cases in our study, the OTS was still relevant.”

The retrospective cohort study included 354 eyes of 354 patients with a mean age of 10.6 years diagnosed with traumatic cataract; 287 eyes had open-globe ocular injuries and 67 had closed-globe injuries.

Patients underwent surgery for traumatic cataract and were treated for amblyopia as needed.

Postoperative examinations were conducted at 6 weeks. The Ocular Trauma Score (OTS) was used to predict visual outcomes, and predictions were compared with final corrected distance visual acuity.

Study results showed a statistically significant improvement in corrected distance visual acuity (P = .000). In the open-globe injury group at 6 weeks, corrected distance visual acuity was better than 20/200 in 181 eyes and 20/40 or better in 110 eyes. In the closed-globe injury group, corrected distance visual acuity was better than 20/200 in 36 eyes and 20/40 or better in 15 eyes. Between-group differences were insignificant.

Among all eyes, final corrected distance visual acuity was better than 20/200 in 214 eyes and 20/40 or better in 123 eyes, the authors said.
