Abstract: Objective To assess the clinical effect of vitrectomy combined with intra-ocular photocoagulation and padding on cyclodialysis with vitreous hemorrhage. Methods Clinical data about 26 patients with traumatic cyclodialysis accompanying vitreous hemorrhage after vitrectomy combined with intra-ocular photocoagulation and padding were retrospectively analyzed. Results The best corrected visual acuity(BCVA), intra-ocular pressure (IOP), anterior chamber depth (ACD), and anterior chamber volume (ACV) of the patients were 0.04±0.10, (6.15±3.87) mmHg (1 mmHg=0.133 kPa), (0.59±0.67) mm, and 71.23±50.81μl higher after operation than before operation (P＜ 0.05).The incidence of transient high intra-ocular pressure and cataract was 11.5%and 84.6%, respectively. Conclusion Vitrectomy combined with intra-ocular photocoagulation and padding is very effective on cyclodialysis with vitreous hemorrhage.Phacoemulsification combined with artificial len implantation can improve the visual acuity of patients with traumatic cyclodialysis accompanying vitreous hemorrhage.
