Prognostic factors for open globe injuries and correlation of Ocular Trauma Score at a tertiary referral eye care centre in Singapore

Abstract

Objective:To evaluate the factors influencing final vision outcome after surgical repair of open globe injuries and to correlate the Ocular trauma score.Materials and Methods:Retrospective case analysis of patients with open globe injuries at a tertiary referral eye care centre in Singapore was performed. Pre-operative factors affecting final vision outcome in patients with open globe injury and correlation of ocular trauma score in our study with international ocular trauma scoring system was performed.Results:Case records of 172 eyes with open globe injury were analyzed. Mean age was 36. 67 years. Mean follow up was 12.26 m. Males were pre-dominantly affected. Initial visual acuity was ≥20/40, 20/50 < 20/200, 20/200- CF, HM– PL and NLP in 24 (14%), 39 (22.7%), 16 (9.3%), 66 (38.4%) and 27 (15.7%) eyes respectively. Final visual acuity was ≤20/40, 20/50 < 20/200, 20/200- 1/200, HM– PL and NLP in 76 (44.2%), 28 (16.3%), 11 (6.4%), 30 (17.4%) and 27 (15.7%) eyes respectively. Ocular trauma score in our study correlates with international ocular trauma scoring system.Conclusion:The present study showed pre-operative variables such as mode of injury, pre-operative visual acuity, traumatic cataract, hyphaema, relative afferent papillary defect, vitreous lossand vitreous hemorrhage to be adversely affecting the final vision outcome. Our study showed a good synchrony with international ocular trauma score (OTS) and based on this study we were able to validate application of OTS in Singapore population. Recognizing these factors can help the surgeon in evidence based counseling.

Visual and ocular morbidity in severe open‐globe injuries presenting to a regional eye centre in New Zealand

“…The Ocular Trauma Score (OTS) was published by Kuhn et al in 2002 following an evaluation of more than 2500 OGIs as a way of predicting the visual outcome using six patient parameters easily assessed at the time of presentation . Its prognostic value has subsequently been validated in published studies from around the world . Predicting outcomes in this situation aids clinical decision making and counselling of patients about the utility of further surgical interventions.…”
