A prospective cohort study on the epidemiology of ocular trauma associated with closed-globe injuries

Abstract

Purpose: To study the epidemiology of mechanical ocular trauma and closed globe injury category by using the Birmingham Eye Trauma Terminology System. Material and Methods: This prospective cohort study involves a prospective cohort study of all the enrolled ocular trauma cases. The data were collected using the international ocular trauma society form through our online MIS data and exported in excel sheet. The data were scrutinized by SPSS 22 using univariate analysis and cross tabulation. Results: Our cohort consisted of 12687 patients with mechanical ocular trauma. There were 7546 (59.4%) eyes with open globe ocular injuries and 5328 (41.9%) with closed globe injuries. Out of the patients with closed globe injuries, 3646 (68.4%) were males and 1682 (31.5%) were females. The mean patient age was 37.4 ± 19.2 years (range, 1–95). Amongst the total closed globe injuries, 4078 (76.5%) were closed globe contusion and 1250 (23.5%) were lemeller laceration. Conclusion: Closed globe injury is an important cause for loss of sight. The condition is more prevalent among the males and younger people. The treatment has significant impact on the visual outcome.
