Abstract: Objective To evaluate the application value for the prognosis of mechanical ocular injury cases using ocular trauma score （OTS）. Methods Four hundred and eleven cases of mechanical ocular trauma were retrospectively reviewed. Of the 449 eyes, there were 317 closed globe injury and 132 open globe injury. OTS variables included numerical values as initial visual acuity, rupture, endophthalmitis, perforating or penetrating injury, retinal detachment and relative afferent pupillary block. The differences between the distribution of the final visual acuity and the probability of standard final visual acuity were compared to analyze the correlation between OTS category and final visual acuity. The different types of ocular trauma were compared. Results Compared with the distribution of final visual acuity in standard OTS score, the ratio in OTS-3 category was statistically different in present study, and no differences were found in other categories. Final visual acuity showed a great linear correlation with OTS category （r=0.71） and total score （r=0.73）. Compared with closed globe injury, open globe injury was generally associated with lower total score and poorer prognosis. Rupture injury had poorer prognosis compared with penetrating injury. Conclusion The use of OTS for the patients with ocular trauma can provide reliable information for the evaluation of prognosis in forensic medicine.
