A prospective study to evaluate the predictive value of ocular trauma score in cases of mechanical eye injuries in a tertiary care hospital

Abstract

Ocular trauma score (OTS) was proposed to predict the visual outcome of patients after ocular trauma, which estimates visual function (visual acuity) after 6 months of ocular trauma. This OTS scale is useful for guiding the treatment and rehabilitation of the patients with eye injury and to provide the valuable information and advice. Aim of this study was to evaluate the predictive value of OTS in cases of mechanical ocular trauma. A prospective interventional study was carried out in a tertiary care centre over a period of 2 years; August 2017 to July 2019. Patients with mechanical eye trauma were included in the study. OTS score was calculated and recorded for each eye at the time of injury. Proper treatment given to each case and followed for six months. Results obtained were compared with standard OTS with respect to final VA. Out of 50 patients mean age was 28.46 years, with majority between 21 to 50 years of age. There were 78% males and 22% were females. Metallic objects were the common source of injury in 27 cases (54%) like iron rod and nail. In cases (fifty eyes) the distribution of OTS variables was; globe rupture 86% (43 eyes), retinal detachment 6% (3 eyes), relative afferent pupillary defect (RAPD) 6% and endophthalmitis 2% (1 eye) respectively. The final visual acuities in OTS categories in our study groups were similar to those in the OTS study group, except for some categories. OTS helps treating ophthalmic team to assess evidence based prognosis of a traumatized eye in advance. With the guidance of OTS the patient and their family can be counselled for further management.
