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.
ObjectiveTo observe the effect of combined operation of internal and external surgery for intraocular hemorrhage of polypoidal choroidal vascular disease (PCV).MethodsRetrospective clinical research. From January to August 2018, 14 eyes of 14 patients with PCV combined with vitreous hemorrhage (VH) with hemorrhagic retinal detachment confirmed by eye examination at the Second Affiliated Hospital of Nanchang University were enrolled in this study. The average disease course was 1.12±0.68 months. The visual acuity decreased from 2 to 14 days. The average time from hemorrhagic retinal detachment to surgery was 6.32±2.82 d. There were 9 eyes with BCVA of light sensing, 3 eyes of hand movement, and 2 eyes of counting fingers. The average macular foveal thickness (CFT) was 564.6±102.2 μm. The range of retinal detachment involves equal or greater than 2 quadrants. 23G vitrectomy surgery was used to remove VH, and subretinal hemorrhage was drained through external scleral drainage to reset the retina. One week and 1 and 2 months after the operation, the eyes were injected with 0.05 ml of ranibizumab in the vitreous cavity. The average follow-up time after surgery was 6.24±1.16 months. One week after the operation, 1, 3, and 6 patients were examined with the same equipment and methods before the operation to observe the condition of BCVA, CFT, intraocular pressure and retinal reattachment. Non-parametric tests were used to compare BCVA before and after surgery.ResultsVH was completely cleared in all eyes, and no iatrogenic retinal hole appeared during the operation. Six months after the operation, there were 1 eye with BCVA of hand movement, 1 eye of counting fingers, 8 eyes of 0.1, 2 eyes of 0.2 and 2 eyes of over than 0.2; the average CFT was 336.4±54.8 μm. Compared with before surgery, the BCVA was significantly improved (Z=－3.711, P=0.000), the CFT was significantly decreased (t=3.212, P=0.006). OCT examination showed that the macular morphology and structure were clearly visible. Of the 14 eyes, 13 eyes were reattached, 1 eye was detached again after silicone oil removal. Intraocular pressure increased in 3 eyes within 1 week after surgery, including 1 eye with a small amount of blood in the anterior chamber. No recurrent VH was found in all eyes during follow-up.ConclusionsCombined internal and external surgery for PCV combined with VH with hemorrhagic retinal detachment is safe and effective.
