Abstract
To evaluate the efficacy of intravitreal bevacizumab with panretinal photocoagulation (PRP) in the treatment of proliferate diabetic retinopathy (PDR) with vitreous hemorrhage (VH). Forty cases (40 patients) with PDR and persistent VH were prospectively enrolled, with a follow-up period of 12 months or more. Intravitreal bevacizumab injection (1.25 mg) was given, followed by PRP when visualization of peripheral fundus could be obtained. A second injection was administered 4 weeks to 6 weeks after the first injection if no signs of VH decrease were noted. Vitrectomy was performed if VH persisted >12 weeks. The vitreous clear-up time (VCUT) and the rate of vitrectomy were compared with those in a historical control group (40 eyes in 40 patients) who were treated with conventional methods. Thirty-one eyes had 1 injection and 9 eyes (22.5%) received 2 injections. Vitreous clear-up time in the study and control groups were 11.9 +/- 9.5 weeks and 18.1 +/- 12.7 weeks (P = 0.02), respectively. Rates of required vitrectomy were 10% in the study group and 45% in the control group (P = 0.01). One or 2 intravitreal injections of 1.25 mg bevacizumab with PRP are associated with rapid regression of VH and may reduce the need for vitrectomy.
