Objective: To evaluate ocular trauma in Songklanagarind Hospital using the ocular trauma score (OTS)
Material and Methods: Data were collected from the records of patients with ocular injuries who had been admitted in Songklanagarind Hospital within the previous 5 years, between 1^st January 1999 to 3^stDecember 2003, to calculate the raw points of ocular trauma score. The sum of these points was used to determine the injury's OTS category, which could predict the final vision.
Results: Between 1st January 1999 to 31st December 2003, 197 patients with ocular injuries were admitted in Songklanagarind Hospital. Ninety-four patients with work-related ocular trauma were determined to be in OTS category 2 (mean raw points 65.29). Twenty patients with transport-related ocular trauma were determined to be in OTS category 2 (mean raw points 55.20). Twenty-six patients with gun or missile-object-related ocular trauma were determined to be in OTS category 3 (mean raw points 76.08). Fourteen patients with sharp-object-related ocular trauma were determined to be in OTS category 2 (mean raw points 57.72). Nine patients with animal-related ocular trauma were determined to be in OTS category 1 (mean raw points 42.89). Nine patients with sport-related ocular trauma were determined to be in OTS category 5 (mean raw points 93.33) and 25 patients with other causes. The most common cause in the work-related group was associated with lawnmower (37 patients), which caused most cases of endophthalmitis (10 patients) and no light perception in final vision (5 patients).
Conclusion: Most cases of ocular trauma in Songklanagarind Hospital were related with occupation, porticularly that of using a lawnmower. These patients were determined to be in OTS category 2, which was related to poor final vision. In addition it was the most common cause of traumatic endopthalmitis in this study.
