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.
