				        	 AIM: To explore the value of ocular trauma score(OTS), initial visual acuity, and ocular structural parameters in the assessment of healing visual acuity from ocular trauma.METHOD: A total of 302 cases(302 eyes)of ocular trauma were selected as subjects, which were accepted and issued clear appraisal opinions by the Academy of Forensic Science from June 2015 to June 2021. The subjects were grouped according to the healing best corrected visual acuity(BCVA)from ocular trauma. Group Ⅰ included 63 cases(63 eyes)with BCVA <3.7; Group Ⅱ included 70 cases(70 eyes)with 3.7≤ BCVA <4.5; Group Ⅲ included 78 cases(78 eyes)with 4.5≤ BCVA <4.9; Group Ⅳ included 91 cases(91 eyes)with BCVA≥4.9. In addition, 77 cases(77 healthy eyes)of ocular trauma were selected as the control group, namely Group Ⅴ. The healing BCVA and ocular structural parameters from ocular trauma and theirs correlation were analyzed, and the random forest(RF)and support vector machine(SVM)model of healing visual acuity was established by the IBM SPSS Modeler 18.0.RESULTS: The initial visual acuity, OTS, the grading of corneas, lenses, and fundus, and the thickness of the retinal never fiber layer of ocular trauma patients were correlated with the healing BCVA(P<0.01). There were significant differences in ocular structural parameters among groups, except the central subfield thickness(P<0.001). The SVM model had higher accuracy of predicting healing visual acuity than the RF model, and the accuracy rate was over 80% when the error was within 0.15.CONCLUSION:OTS and ocular structural examination can provide effective information for the clinical forensic medicine appraisal of visual dysfunction after ocular trauma, and they are valuable in discriminating camouflage of visual dysfunction.
