目的 探讨保留晶状体前囊膜技术在增生性糖尿病视网膜病变(PDR)手术治疗中的临床效果.方法 系列病例研究.对伴有晶状体混浊和累及眼底后极部的牵拉性视网膜脱离或牵拉-孔源性视网膜脱离的51例(58只眼)PDR患者,在行玻璃体切除手术中,采用经睫状体平坦部切除或超声粉碎吸出晶状体核及皮质并保留前囊膜的技术,处理混浊的晶状体,完成玻璃体手术后给予硅油充填.术后对晶状体前囊膜照相,并对其透明度进行分级评价,对与手术相关的并发症及其处理方法、患者视力和眼压、视网膜复位情况进行分析.结果 玻璃体切除硅油充填并保留晶状体前囊膜的58只眼中,晶状体前囊膜透明度:A级26只眼(44.8%),B级20只眼(34.5%),C级7只眼(12.1%);D级5只眼(8.6%).46只眼(79.3%)术后最佳矫正视力≥0.05,21只眼接受二期人工晶状体植入术.最终7只眼因视网膜不能复位,黄斑裂孔未闭合,而未行硅油取出术.手术并发症:误切虹膜1只眼,硅油进入前房7只眼,虹膜新生血管形成及新生血管性青光眼各1只眼,术后高眼压4只眼,继发性黄斑和视网膜前膜11只眼,黄斑裂孔2只眼.结论 保留晶状体前囊膜,酌情行二期人工晶状体植入术,是处理严重PVR眼的一种较好方法.晶状体上皮细胞残留和积血的长期存在是晶状体前囊膜混浊的主要原因,硅油进入前房是玻璃体切除术中应用保留晶状体前囊膜技术的主要并发症之一. 相似文献

OBJECT: To compare the results of vitrectomy for phakic cases and those of aphakic cases with proliferative diabetic retinopathy (PDR) accompanied by rubeosis iridis. MATERIALS & METHODS: We reviewed 34 eyes of 24 cases that underwent vitrectomy for proliferative diabetic retinopathy with rubeosis iridis. RESULT: Phakic eyes needed significantly more reoperations (p < 0.001) than aphakic eyes. Aphakic eyes had significantly more successful visual results (p < 0.05) and better control of intraocular pressure (p < 0.005) than phakic eyes. CONCLUSION: This study showed the possibility that phakic eyes had more ischemic retina producing more angiogenic factors than aphakic eyes which had the same grade of rubeosis iridis. Phakic eyes with pre-operative rubeosis iridis need thorough clearance of ocular ischemia by panretinal photocoagulation. 相似文献

目的 探讨晶状体摘除对糖尿病视网膜病变(diabetic retinopathy,DR)玻璃体视网膜手术(vitreoretinal surgery,VRS)效果的影响.方法 回顾性分析2001年2月至2007年8月行VRS的68例(80只眼),比较摘除晶状体眼同人工晶状体眼与保留晶状体眼的手术效果,随访5~63个月,平均(12.24±9.13)月.结果 术后87.27%的保留晶状体眼及68%的摘除晶状体眼视力提高或不变(x2=4.191,P=0.062);再次VRS率在保留晶状体组为12.7%,摘除晶状体组20%(x2=0.713.P=0.502);解剖复位率在保留和摘除晶状体眼分别为92.73%和96%(x2=0.314,P=1.000);保留晶状体组和摘除晶状体组各2只眼发生虹膜红变(x2=689,P=0.585),差异均无统计学意义.术后摘除晶状体组前房纤维素性渗出和黄斑水肿的发生率较保留晶状体组增加,差异有统计学意义(P<0.05).结论 晶状体摘除并不增加DR再次VRS率和虹膜红变的发生率,但术后前房纤维素性渗出和黄斑水肿的发生率增加. 相似文献

Complications of vitreous surgery for diabetic retinopathy. II. Postoperative complications 总被引:3,自引:0,他引:3
One hundred seventy-nine eyes were analyzed to determine the incidence of postoperative complications after vitrectomy for proliferative diabetic retinopathy. One hundred twenty-nine (72%) of the 179 eyes achieved improved vision, and 117 (65%) were considered visual successes with final vision in the functional range of 5/200 or better. Corneal epithelial defects occurred in 51 eyes (28%), but severe corneal complications were rare, and no eye developed corneal clouding as the sole cause of later visual loss. The lens was retained in 128 eyes (75%), and visually significant lens opacities occurred later in 17% of the phakic eyes. Postoperative iris neovascularization was reduced by not removing the lens, and rubeosis iridis occurred in 15 (13%) of 114 phakic eyes and in 21 (32%) of 65 aphakic eyes (P = 0.012). Vitreous hemorrhage was present in 75% of eyes immediately after surgery and cleared in an average of 6.2 weeks in phakic eyes and 5.4 weeks in aphakic eyes. Fifty-two eyes (29%) had recurrent vitreous hemorrhage after the initial postoperative period. New retinal detachment occurred after surgery in 16% of eyes and was treated successfully in 38%. Reoperations were done in 45 eyes (25%), and 32 (71%) of these were for repair of retinal detachment or removal of nonclearing vitreous hemorrhage. Six eyes (3%) developed phthisis bulbi, and one other eye was enucleated. 相似文献

Posterior chamber intraocular lens implantation during diabetic pars plana vitrectomy 总被引:6,自引:0,他引:6
Combined cataract removal, posterior chamber intraocular lens (PC IOL) implantation, and pars plana vitrectomy were performed in 15 diabetic patients who presented with coexisting cataract and vitreoretinal complications from proliferative diabetic retinopathy (PDR). Posterior chamber IOLs were placed anterior to the anterior lens capsule after pars plana lensectomy and vitrectomy in nine eyes, whereas extracapsular cataract extraction (ECCE) with PC IOL placement was performed before vitrectomy in six eyes. Panretinal laser endophotocoagulation was applied in 13 of the 15 eyes as an important part of the operative procedure. Because of inactive diabetic retinopathy or satisfactory preoperative panretinal photocoagulation, 2 of the 15 eyes did not receive laser endophotocoagulation. Visual acuity was improved in 12 eyes and was similar to preoperative vision in 3 eyes. After a minimum of 6 months and a maximum of 28 months of follow-up, the visual results are the following: 20/40 or better (4 eyes), 20/50 to 20/200 (5 eyes), 20/400 to 5/200 (5 eyes), and hand motions (1 eye). Although 5 of the 15 eyes required secondary vitreoretinal procedures, neovascular glaucoma and complications attributable to the IOL did not occur. A recurrent postoperative retinal detachment (RD) developed with subsequent hypotony and rubeosis iridis in 1 of the 15 eyes. 相似文献

增殖型糖尿病视网膜病变玻璃体切割手术后的视力及影响因素 总被引:11,自引:2,他引:9
作者分析增殖型糖尿病视网膜病变(proliferative diabetic retinopathy,PDR)合并严重玻璃体出血、黄斑部视网膜前出血、牵拉性视网膜脱离、牵拉性视网膜脱离并发孔源性视网膜脱离共81只眼进行玻璃体切割手术的结果。83.9%的患眼手术后视力获得不同程度的改善,PDR的严重程度对手术后视力有一定的影响,V期患者手术后出血率较高。虹膜红变的发生率与PDR的严重程度无关,但晶体切割眼的虹膜红变发生率高于有晶体眼。手术后视网膜脱离和出血不吸收均可导致虹膜红变的发生。

Forty eyes in 39 patients with proliferative diabetic retinopathy, vitreal hemorrhage and progressive neovascularization in at least 3 fundus quadrants were treated with panretinal xenon photocoagulation immediately after pars plana vitrectomy. Lens extraction was performed on 7 eyes and 2 eyes were aphakic. Six months after treatment, 68% of the eyes showed an improvement in vision, 25% had vitreal rebleeding and 11% developed rubeosis iridis. While treatment had no effect on peripheral rubeosis iridis in 5 eyes, all 7 eyes with pupillary rubeosis iridis showed complete regression. The results indicate the clinical value of combining, pars plana vitrectomy with panretinal xenon photocoagulation in selected patients. 相似文献

PURPOSE: The postoperative outcome was evaluated in each group of surgical indications of vitreous surgery for proliferative diabetic retinopathy (PDR), to investigate the factors responsible for postoperative visual prognosis. METHODS: Primary vitrectomy was performed in 119 eyes of 92 patients with PDR. Average postoperative follow-up period was 19 months. The indications for vitrectomy included vitrous hemorrhage in 58 eyes, macular tractional retinal detachment in 17 eyes, extramacular tractional retinal detachment in 10 eyes, macular heterotopia in 11 eyes, and progressive fibrovascular proliferation in the posterior fundus in 23 eyes. RESULTS: The visual acuity finally improved by 2 lines or more in 91 eyes (77%), remained unchanged in 10 eyes (8 %), and decreased by 2 lines or more in 18 eyes (15%). Final postoperative visual acuity was significantly better in cases of vitreous hemorrhage or progressive fibrovascular proliferation in the posterior fundus than in others. Preoperative rubeosis iridis and macular tractional retinal detachment were probably responsible for the final visual impairment, and intraocular tamponade affected the difference in visual prognosis between the groups of surgical indication. Multivariate analysis in all cases revealed that factors influencing visual outcome were preoperative rubeosis iridis and anemia. CONCLUSION: Rubeosis iridis and macular tractional retinal detachment were prognostic factors of the surgery. Vitrectomy for PDR may be effective in improving postoperative visual acuity if performed in the early stage of progressive fibrovascular proliferation in the posterior fundus after sufficient retinal photocoagulation. 相似文献

Posterior chamber intraocular lens implantation in eyes with inactive and active proliferative diabetic retinopathy 总被引:9,自引:0,他引:9
We reviewed the records of 2,100 consecutive eyes that had undergone extracapsular cataract extraction with intraocular lens implantation between January 1981 and December 1989. Of these eyes, 21 had inactive and four had active proliferative diabetic retinopathy at the time of cataract extraction. Twenty-one eyes with inactive proliferative diabetic retinopathy received extracapsular cataract extraction with posterior chamber intraocular lens implantation, and four eyes with active proliferative diabetic retinopathy had both extracapsular cataract extraction with posterior chamber intraocular lens implantation and pars plana vitrectomy with endophotocoagulation. The mean follow-up period was 27 months. Final visual acuity was 20/40 or better in 12 of 25 eyes (48%). Of 25 eyes, five (20%) showed progression of the retinopathy after the operation, and two (8%) developed macular edema. Extracapsular cataract extraction and posterior chamber intraocular lens implantation was well tolerated in most eyes. 相似文献
