AIM: To analyze the epidemiological characteristics of ocular trauma, classify ocular trauma internationally according to OTS standards set by US Association of Ocular Trauma, and to provide objective and accurate information on the severity and prognosis of ocular trauma, guide us to work out the most reasonable diagnostic and therapeutic programs accurately and quickly.

METHODS: Statistics of 251 cases(252 eyes)with ocular trauma on basic information( on gender, age, left or right eye, injury time, injury types, vulnerants and complications, etc.), were summarized and converted into OTS categories(on early clinical vision, with or without ocular rupture, endophthalmitis, perforating injury, retinal detachment, merging to relative afferent pupillary defect, etc.). The likelihood of the final visual acuity was calculated according to the OTS data sheet and compared with that in the OTS study. Scores of patients in different ocular trauma level were compared.

RESULTS: The likelihood of the final visual acuity of this research showed no significant difference from the final visual acuity calculated according to OTS data sheet(no light perception, light perception/hand motion, 0.005-0.095, 0.1-0.4, ≥0.5). The final visual acuity showed positive correlation significantly to the early visual acuity(r=0.772,P=0.000). The case number of final visual acuity at 0.5 in category-1 of OTS was 0. So was the case number of final visual acuity with no light perception in category-5 of OTS.

CONCLUSION: OTS may contribute greatly to initial diagnosis and therapeutic schedule in eye injuries.
