Visual outcome after open globe injury and its predictive factors in Korea

Abstract

Background: To determine visual outcomes and prognostic factors of open globe injury in Korea and to assess the prognostic power of Ocular Trauma Score (OTS) model.

Methods: The medical records of 194 consecutive patients (194 eyes) with open globe injury were reviewed. Data including demographics, mechanisms of injuries, wound sizes and locations, initial visual acuities, presence of intraocular damage and adjacent tissue injuries, and final visual acuities, which was defined as visual acuities at 1 year, after injury were collected and analyzed. Comparison of final visual acuities with those of the OTS study was also performed.

Results: The study group consisted of 160 (82.5%) male and 34 (17.5%) female subjects. The average age was 38.2 ± 17.8 years (range, 2-91 years). One year after injury, visual acuity of light perception or better was attained in 78.4% of the patients, and 20/200 or better in 58.2%. In multivariate analysis, poor initial visual acuity, presence of retinal detachment and relative afferent papillary defect, and larger wound (>10 mm) were related to poor final visual acuities. Final visual acuities assessed using OTS categories were similar to those of OTS study in OTS category 3, 4, and 5, and more favorable in OTS category 1 and 2.

Conclusion: We have identified prognostic factors of open globe injury including initial visual acuity, presence of retinal detachment, relative afferent papillary defect, and wound length. OTS may have prognostic value in open globe injuries in Asian patients.
