Four-port bimanual technique in severe vitreoretinopathy / 眼科

ABSTRACT

Objective To evaluate the effect of the four-port bimanual vitrectomy illuminated by assistants in severe vitreo-retinopathy. Design Retrospective case series. Participants 39 eyes of 39 patients of severve vitreoretinopathy. Methods Four-port bimanual vitrectomy illuminated by assistants were applied. All the patients were followed up for 6 to 18 months. The best corrected visual acuity and reattachment of retina were observed. Main Outcome Measures Operation duration,effect,and complications. Results All the 39 eyes were successfully operated. Time of membrane stripping of membrane ranged from 4 to 50 min (mean 16 min). No complications were found in operation. Retinal redetachment occurred in 4 case and vitreous rebleeding in 2 cases. No sclerotomy was found. Best corrected visual acuity improved in 35 eyes defined as 2-line increase in visual acuity chart or visual acuity from light perception to finger count post-operation. Conclusion Four-port bimanual vitrectomy has more advantages in the operation procedure. It is a promising method in treating patients with severve vitreoretinopathy.
