Intraocular Fibrin Glue to Lower the Risk of Postoperative Vitreous Hemorrhage After Diabetic Pars Plana Vitrectomy.

Abstract

To investigate the use of intraocular fibrin glue to lower the risk of vitreous hemorrhage (VH) after pars plana vitrectomy (PPV) in eyes with diabetic VH or traction retinal detachment. A matched, case-control, single-surgeon, pilot study of patients undergoing PPV for diabetic VH or traction retinal detachment with versus without fibrin glue was performed. Thirty-nine patients (13 glue and 26 control patients) were included. In the glue group, mean (SD) logarithm of the minimum angle of resolution visual acuity (Snellen) significantly improved from 1.53 (0.6) (20/678) to 0.99 (0.9) (20/195) at postoperative month 6 ( P = 0.03). In the control group, mean logarithm of the minimum angle of resolution visual acuity also improved from 1.45 (0.8) (20/564) to 1.17 (0.9) (20/296) at postoperative Month 6 ( P = 0.3). Persistent post-PPV VH was similar between the 2 groups (15.4% in both groups, P > 0.99). However, early recurrent VH (<3 months post-PPV) was seen in 34.6% in the control group and none in the glue group ( P = 0.02). No intraocular inflammatory events were seen in the glue group. Intraocular fibrin glue may be a safe adjuvant in diabetic vitrectomy and may reduce the rate of early recurrent postoperative VH.
