Abstract:
PURPOSE: To evaluate the efficacy and complication of autologous plasmin (AP) injected before vitrectomy for rhegmatogenous retinal detachment (RRD). METHODS: Intravitreal AP injection (0.2 ml) was performed on the eyes without posterior vitreous detachment (PVD) 20 minutes before the vitrectomy for RRD. The extent of PVD was evaluated intraoperatively. Surgical PVD induction was performed and the ease of the procedure was graded. The extent of PVD, ease of PVD induction, and complications (including incidence of iatrogenic retinal break) were compared to those of the control eyes. In order to evaluate complications and measure activated partial thromboplastin time, a microbial culture of injected AP was performed and the rate of postoperative intraocular hemorrhage was investigated. Change in visual acuity and the rate of retinal reattachment were compared in order to evaluate the long-term surgical outcome. RESULTS: The extent of PVD was greater in the AP group than in the control group, and vitreal separation was facilitated by intravitreal AP injection. However, ease of PVD induction and frequency of iatrogenic retinal break found were not significantly different between cases and controls. Neither postoperative intraocular hemorrhage nor systemic coagulation abnormality occurred. Postoperative endophthalmitis and positive microbial culture of the AP solution were also not reported. There was no significant difference in the change in visual acuity and the rate of retinal reattachment between the two groups. CONCLUSIONS: Intravitreal AP injection can facilitate vitrectomy for RRD and has no effect on the rate of retinal reattachment.
