ABSTRACT
PURPOSE: To determine the prognostic value of the Ocular Trauma Score (OTS) in patients with traumatic open globe injuries. METHODS: A retrospective chart review of patients with traumatic open globe injuries seen in a tertiary eye center in the Philippines from 2008 to 2013. Patients with traumatic open globe injuries who were at least 18 years of age upon first consult and with documented visual acuity at the first, third and sixth months of follow up were included in the study. The following data were collected: age, sex, occupation, manner of injury, type of injury, location of injury, presence of globe rupture, endophthalmitis, perforation, retinal detachment and afferent pupillary defect, and visual acuity (VA) at presentation, month 1, month 3 and month 6. The OTS was computed from the available data. RESULTS: A total of 114 records were included. Open-globe (OG) injuries were more common in males (86.8%), between 18 - 39 y/o (64.9%) and who were manual workers (74.6%). Most were occupation-related (64%), seen within 1 - 3 days (55.3%), and treated both medically and surgically (92.1%). The most common type of OG injury was a penetrating laceration (82.5%), had an initial VA of 4/200 to light perception (57.9%), had no afferent pupillary defect (APD) (84.2%), and was located at zone I (73.7%). The most common OTS anatomical factor seen, when present, was an APD (15.8%). In all months, there was a significant positive correlation between OTS score and visual acuity. CONCLUSION: The OTS appeared to predict visual outcome as early as the first month post-injury, although correlation still exists at the 3rd and 6th months.
