Assessment of visual prognosis using Ocular Trauma Score in open globe injury at a tertiary care center

Abstract

Aims and Objectives: The aim and objective of this study was to assess the visual prognosis in open globe injury patients using the “Ocular Trauma Score (OTS).” Methodology: A prospective study of 100 patients with open globe injury attending a tertiary referral eye care center, Chennai, was carried out for a period of 12 months from February 1, 2018, to February 1, 2019. Results: The mean age of presentation was 40 years. Males (75%) were more commonly injured compared to females (11%). The right eye (65%) was more commonly injured than the left eye (35%). Out of the 100 patients, 96 patients underwent surgical management and 4 patients were managed conservatively. Out of the 96 patients, 26% had globe ruptures, 11% had relative afferent pupillary defect, 10% had perforating injuries, 8% had retinal detachment, and 4% had endophthalmitis. OTS was 1 in 9% of patients, 2 in 30%, 3 in 35% patients, 4 in 15% patients, and 5 in 11% patients, indicating that most of the patients had poor visual acuity at the time of presentation with an OTS value of 1–3. At the end of 6 weeks, 18% of the patients had a vision of no perception of light, 21% had a vision of percentage of light/hand movements, 25% had 1/200–19/200, 18% had 20/200–20/50, and 18% had >20/40. Majority of the patients had a visual acuity between 1/200 and 19/200. The results were analyzed with the OTS value chart. Conclusion: OTS is a comprehensive score to predict final visual outcome in patients with open globe injury, which can be widely used for counseling ocular trauma victims. OTS calculated at the initial evaluation has predictive value in patients with open globe injury.
