Objective To observe the efficacy of vitrectomy for vitreous hemorrhage in patients with polypoidal choroidal vasculopathy (PCV). Methods Fourteen patients (14 eyes) of PCV with vitreous hemorrhage diagnosed by routine ophthalmologic examination, A and/or B mode ultrasound, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were enrolled in this study. The patients included eight males (eight eyes) and six females (six eyes), with the mean age of (58.7plusmn;6.0) years. All patients received vitrectomy with silicone oil and C3F8 gas tamponade. There were eight eyes received photodynamic therapy (PDT) after surgery. The retinal reattachment, visual acuity, pathological lesion degree and complications were comparatively analyzed. Results Among 14 eyes, six eyes (42.9%) recovered, seven eyes (50.0%) improved, and one eye (7.1%) aggravated. Ten eyes achieved retinal reattachment after surgery, while four eyes developed retinal detachment after the first surgery. The retina remained attached in these three eyes after silicon oil tamponade, C3F8 gas tamponade and scleral buckling, respectively; but one eye maintained silicon oil without special treatment. Thirteen eyes (92.9%) achieved retinal reattachment finally. Five eyes of them occurred hyphema one to seven days after surgery, but hyphema was absorbed and intraocular pressure was stable after douche of anterior chamber and pharmacotherapy. The vision improved with more than two lines in one eyes, improved with one to two lines in one eye, unchanged in 10 eyes, and decreased in two eyes. Of eight eyes who underwent PDT, abnormal vessels regressed in five eyes, abnormal vessels remained in three eyes. Conclusions Vitrectomy can remove cloudy refracting media for PCV with vitreous hemorrhage. The combined treatment of vitrectomy and PDT can improve or stabilize visual function,is an effective therapy for the PCV with vitreous hemorrhage.
