Abstract:
Objective T o evaluate the application value for the prognosis of m echanical ocular injury cases using ocular traum a score (O TS). Methods Four hundred and eleven cases of m echanical ocular traum a w ere retrospectively review ed. O f the 449 eyes, there w ere 317 closed globe injury and 132 open globe injury. O T S variables included num erical values as initial visual acuity, rupture, endophthalm itis, perforat-ing or penetrating injury, retinal detachm ent and relative afferent pupillary block. T he differences be-tw een the distribution of the final visual acuity and the probability of standard final visual acuity w ere com pared to analyze the correlation betw een O T S category and final visual acuity. T he different types of ocular traum a w ere com pared. Results C om pared w ith the distribution of final visual acuity in standard O T S score, the ratio in O T S-3 category w as statistically different in present study, and no differences w ere found in other categories. Final visual acuity show ed a great linear correlation w ith O T S category (r=0.71) and total score (r=0.73). C om pared w ith closed globe injury, open globe injury w as generally associated w ith low er total score and poorer prognosis. R upture injury had poorer prognosis com pared w ith penetrating injury. Conclusion T he use of O T S for the patients w ith ocular traum a can provide re-liable inform ation for the evaluation of prognosis in forensic m edicine.
