Abstract: Objective To analyze types, mechanism and forensic identification for traumatic visual loss. Methods 109 cases of the evaluation for impairment and disability on traumatic visual loss were retrospectively analyzed, including interocular differences, anisometropia, left or right eye and the distributions of visual acuity, etc. Results The male-to-female ratio was 5.8:1, mainly 30~59 years of age. The ratio of monocular versus binocular injuries was 17.17:1. The ratio of left versus right injured eye was 1.39:1 in intentional injury cases. 115 eyes were injured, 83 of which were in low vision or blindness. 95 patients(87.16%) had large interocular differences( ≥ 3 lines). There were 9 patients with anisometropia from 2.25D to 6.00D and 23 patients with anisometropia larger than 6.00D. Conclusion Interocular differences and anisometropia are common in practice, which are not included in the expertise standard yet. Functional vision should be considered when developing the expertise standard.
