黄斑皱褶是黄斑区视网膜前膜增厚和收缩引起的一种黄斑疾病,以前膜形成、黄斑内层视网膜增厚、视力下降为特点,其引起视力下降的主要原因是黄斑前膜遮挡中心凹、黄斑区视网膜变形和黄斑水肿[1]。因此,剥除黄斑前膜以恢复黄斑区解剖结构是临床治疗的主要目标,黄斑前膜剥除术或联合内界膜剥除术是目前治疗黄斑皱褶的主要手术方式[2]。 相似文献

PURPOSE: To evaluate the surgical efficacy of pars plana vitrectomy on eyes with diabetic macular edema in the presence or absence of a complete posterior vitreous detachment and with or without an epimacular membrane. METHODS: Pars plana vitrectomy was performed on 30 eyes of 29 cases with diabetic macular edema. Visual acuity was measured, and retinal thickness was determined by optical coherence tomography before and after vitrectomy. To evaluate the relationship between the effects of vitrectomy and the presence or absence of posterior vitreous detachment and/or epimacular membrane, all eyes were placed into one of four groups: group A, eyes with posterior vitreous detachment and epimacular membrane; B, eyes with posterior vitreous detachment and without epimacular membrane; C, eyes without posterior vitreous detachment and with epimacular membrane; and D, eyes without posterior vitreous detachment and without epimacular membrane. The expression of vascular endothelial growth factor and interleukin-6 was investigated immunohistochemically in epimacular membrane specimens obtained from seven eyes with diffuse diabetic macular edema. RESULTS: The postoperative mean visual acuity (0.653 +/- 0.350: mean +/- SD logarithm of minimal angle of resolution [logMAR]) was significantly better than the mean preoperative visual acuity (0.891 +/- 0.319 logMAR; Wilcoxon signed-rank test, P =.0007). The postoperative foveal thickness (264.5 +/- 118.6 microm) was significantly thinner than the preoperative foveal thickness (477.8 +/- 147.7 microm; Wilcoxon signed-rank test, P <.0001). There were no significant differences in the improvement of visual acuity and decrease of foveal thickness between the four groups (Kruskal-Wallis test, P =.13, P =.65, respectively). All of the epimacular membranes obtained at surgery expressed vascular endothelial growth factor and interleukin-6. CONCLUSIONS: These results demonstrated that vitrectomy with removal of epimacular membrane is generally an effective procedure in reducing diabetic macular edema, and the outcome does not depend on the presence absence of posterior vitreous detachment and epimacular membrane. 相似文献

PURPOSE: To describe the presenting features, histopathology, and surgical outcome in a group of patients with rapidly progressive macular pucker. DESIGN: Retrospective interventional noncomparative case series. PARTICIPANTS: Five patients. METHODS: Review of case notes and the existing literature. RESULTS: All five patients had rapidly progressive visual loss and metamorphopsia over 2 weeks to 3 months, secondary to macular pucker after retinal tears or detachment. Vitrectomy and epiretinal membrane removal was performed within 1 month of diagnosis. In the absence of complications, there was rapid recovery of the visual acuity with resolution of metamorphopsia within 6 weeks to 3 months. Surgical complications limited the visual outcome in two cases. Histopathologic examination of epiretinal membrane removed from two of the cases suggests that these tend to form tubuloacinar structures and contain more retinal pigment epithelium-derived cells than tissue excised from cases with idiopathic macular pucker. CONCLUSIONS: Patients with acute macular pucker have precipitous visual loss caused by epiretinal membrane formation after retinal tear or detachment. Early surgery in these patients results in rapid recovery of visual acuity and resolution of metamorphopsia. The clinical features and comparative immunohistochemistry suggest that acute macular pucker is a distinct clinicopathologic entity. 相似文献

Surgery of idiopathic epimacular membranes. Prognostic factors] 总被引:1,自引:0,他引:1
Seventy consecutive cases of idiopathic epimacular membrane removal were reviewed in order to evaluate the prognosis factors of this surgery. The characteristics analyzed where the duration of the symptoms, pre and postoperative visual acuity and the macular changes on fluorescein angiography. The mean follow-up after surgery was 9 months. Mean preoperative visual acuity was 0.17 and the mean best postoperative visual acuity 0.43. Visual acuity improved by 2 lines or more in 81% of the cases and the mean improvement was 3.5 lines. The complications of epimacular membrane surgery included nuclear cataract (10 eyes underwent cataract surgery), peripheral retinal breaks (3%), and retinal detachment (3%) successfully operated. Three of the main preoperative data were related to better postoperative visual outcome: preoperative visual acuity: eyes with visual acuity of 0.16 or more tended to have better postoperative vision than eyes with poorer preoperative vision (mean postoperative visual acuity 0.5 and 0.34 respectively; p < or = 0.05); duration of visual impairment before surgery: eyes with a visual impairment of less than 2 years had better postoperative vision than the others (mean postoperative visual acuity, 0.5 and 0.3 respectively; p < or = 0.05); the absence of preoperative angiographic macular edema: eyes without preoperative macular edema had better postoperative vision than the others (mean postoperative visual acuity: 0.5 and 0.4 respectively; p < or = 0.05). The normal postoperative pattern of macular vessels and foveolar shape was also a statistically significant factor of good vision recovery. 相似文献

Methods From February 2006 to October 2008, 42 patients with complicated retinal detachment were underwent successful vitrectomy. According to ILM peeling or not during vitrectomy, all patients were divided into two groups: the group Ⅰ (peeling ILM) 20 eyes, the group Ⅱ (not-peeling ILM) 22 eyes, followed up for 12-26 months, mean at 18± 8 months. All of those were examined for visual acuity, fundus photography, ophthalmologic A/B ultrasonic imaging, OCT preoperatively and postoperatively,the parts of those were examined for FFA postoperatively. The epimacular membrane formation was decided by the last chance at one year to two years after removal of silicone. The epimacular membrane formation of two groups was analyzed statistically. Results No epimacular membrane formation was seen in group Ⅰ . The epimacular membrane formation of two eyes was verified by OCT or/and FFA before removal of silicone, and the epimacular membrane formation of four eyes was verified by OCT or/and FFA after removal of silicone.The comparison of epimacular membrane formation between group Ⅰ and group Ⅱ was statistically significant.Conclusion ILM peeling at the macular during vitreous surgery for the treatment of complicated retinal detachment may effectively prevent epimacular membrane formation. 相似文献

Surgical management of retinal detachment secondary to acute retinal necrosis: clinical features,surgical techniques,and long-term results 总被引:4,自引:0,他引:4
Ahmadieh H Soheilian M Azarmina M Dehghan MH Mashayekhi A 《Japanese journal of ophthalmology》2003,47(5):484-491
PURPOSE: To describe the clinical features of complicated retinal detachment secondary to acute retinal necrosis (ARN) and to present the long-term results of vitreous surgery in these cases. METHODS: A retrospective study was conducted on 16 immunocompetent patients (18 eyes). The average follow-up period was 60 months. RESULTS: Proliferative vitreoretinopathy (PVR) grade C, with the predominance of anterior PVR, and characteristic changes in the vitreous base area were present in all cases before surgery. All eyes underwent vitrectomy, membrane peeling, endolaser photocoagulation, and intraocular tamponade without scleral buckling. Additional procedures were performed in 13 eyes. Retinal reattachment was achieved in the 18 eyes (100%) in the short term. Variable degrees of reproliferation occurred in all cases after surgery. Other delayed complications included ocular hypotony, macular pucker, peripheral retinal neovascularization, and severe preretinal fibrosis. Improvement of visual acuity occurred in 13 eyes (72.2%). Eleven eyes (61.1%) achieved final ambulatory visual acuity of 5/200 or better. CONCLUSIONS: Rhegmatogenous retinal detachment secondary to ARN has characteristic clinical features. Severe proliferative vitreoretinopathy with the predominance of anterior PVR develops rapidly. Reproliferation is the most important late postvitrectomy complication necessitating multiple surgical procedures in these cases. The visual results remain unfavorable due to the destructive nature of ARN. 相似文献
