ABSTRACT
Objective:To observe the effect of combined operation of internal and external surgery for intraocular hemorrhage of polypoidal choroidal vascular disease (PCV).Methods:Retrospective 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.Results:VH 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. Conclusions:Combined internal and external surgery for PCV combined with VH with hemorrhagic retinal detachment is safe and effective.
ABSTRACT
Objective To study the effects of lucentis preventing vitreous hemorrhage after vitrectomy for diabetic retinopathy combined with iris neovascularization.Methods The clinical data of 70 patients (70 eyes) underwent vitrectomy for diabetic retinopathy combined with iris neovascularization during 2009 to 2015 in our hospital were retrospectively analyzed.The control group (30 eyes) accepted panretinal photocoagulation (PRP),re-vitrectomy,cyclocryotherapy,and the study group (40 eyes) had the 0.5mg lucentis in addition.The follow-up time was 3 months,and the visual acuity,IOP,vitreous hemorrhage,INV regression and complication were observed.Results At 1 month,2 months in the follow-up,the visual acuity of study group was better than the control group,but there was no significant difference along with the follow up.The average preoperative IOP was (26.312 ±4.566) mmHg (1 kPa =7.5 mmHg) in the study group and (24.586 ±5.783) mmHg in the control group,and at the end of the follow up,IOP was (18.576 ±4.762) mmHg in the study group and (28.587 ±7.786) mmHg in the control group,there was statistical difference between the two groups (P =0.041).The intraoperative and postoperative anterior chamber or vitreous hemorrhage occurred in 15 cases,5 cases of the control group,and 3 cases,1 case of the control group,there were significant differences (all P =0.000).At the end of the follow up,3 eyes (7.5％) developed to NVG in the study group and 10 eyes (33.3％) in the control group,there was statistical difference (P ＜ 0.05).Conclusion Lucentis can effectively eliminate the new vessels,reduce the incidence of neovascularization glaucoma and vitreous hemorrhage for patients after vitrectomy for diabetic retinopathy combined with iris neovascularization,and improve the visual acuity in a short time.
