Methods The clinical data of 30 eyes of 27 patients (20 males and 7 females) with Eales disease who underwent vitrectomy were retrospectively analyzed. The age was ranged from 15 to 54 years old, with a mean of 30.7 years. The best corrected visual acuity (BCVA) was ranged from hand movement to 0.5. The patients were divided into the vitreous hemorrhage group (3 eyes ), proliferative vitreoretinopathy group (14 eyes), local retinal detachment group (7 eyes), and wide retinal detachment group (6 eyes) according to the results of examinations. The standard pars plana vitrectomy (PPV) were performed and scleral buckling, lensectomy, endolaser, transscleral cryotherapy/cautery, membrane removal, retinotomy, fluid-air exchange, intravitreal injection of triamcinolone, gas/oil tamponade can be combined if necessary. Those eyes underwent 1 to 8 times (with a mean of 2.4 times) of surgery. The follow-up was ranged from 6 months to 10 years. The BCVA, retinal reattachment, complications before and after surgery was comparatively analyzed. Results At the end of the follow-up, the BCVA was ranged from light perception to 1.5. The BCVA was >0.1 in 24 eyes (80.0%) ,0.03 in 1 eye (3.3%), counting finger in 1 eye (3.3%), hand moving in 3 eyes (10.0%) and light perception in 1 eye (3.3%). The BCVA improved in 22 eyes (73.3%), stable in 2 eyes (6.7%) and decreased in 6 eyes (20.0%). The differences are statistically significant between pre- and postoperative BCVA (t=5.132, P<0.01). The BCVA of wide retinal detachment group was less than other 3 groups (F=4.570, P<0.05); while the BCVA of vitreous hemorrhage group, proliferative vitreoretinopathy group and local retinal detachment group was the same (P>0.05). Complete retinal reattachment was achieved in all eyes at the next day after PPV. At the end of the follow-up, retina reattached in 24 eyes without silicone oil tamponade, local retinal detachment occurred in 1 eye (the patient refused further surgery) and silicone oil tamponade-dependant retinal reattachment 5eyes. During the follow-up, 16 eyes (53.3 %) had developed some complications. Conclusions Vitrectomy is an effective way to cure serious complications of Eales disease. The BACV prognosis of patients with wide retinal detachment is poor. 相似文献

BACKGROUND: Coats disease is a retinal vasculopathy of unknown cause. Untreated cases usually lead to an exudative retinal detachment and rubeosis iridis with secondary glaucoma. Photocoagulation and/or cryotherapy are generally the first interventions in treating the disease. Pars plana vitrectomy may be indicated in cases of vitreous hemorrhage or retinal detachment. METHODS: We performed pars plana vitrectomy in 9 eyes with Coats disease between 1992 and 1999. A retinal detachment was present in 3 cases, and three showed a vitreous hemorrhage. In two cases surgery was indicated because of paramacular localization of the pathological vessels with associated exudations. RESULTS: The two cases with paramacular involvement showed improvement in visual acuity of eight lines. In the remaining cases visual acuity remained within two lines compared to the initial visual acuity. All eyes except one could be saved. CONCLUSION: Pars plana vitrectomy is a useful option in treating advanced Coats disease, especially in cases associated with vitreous hemorrhage or retinal traction. 相似文献

Purpose: We determined the efficacy of pars plana vitrectomy in a series of patients with complicated Eales disease.Methods: Clinical records were reviewed on 47 consecutive patients (49 eyes) who underwent vitrectomy for persistent vitreous hemorrhage (PVH) and/or traction retinal detachment (TRD) with neovascular membranes (NVM). All cases were divided into 4 subgroups of eyes with PVH (without obvious NVM, n = 9), NVD (NVM from the optic disc, n = 10), NVP (peripheral NVM, n = 11), or ENV (extensive NVM and logn-standing TRD,n- 17).Results: The study included 8 women and 39 men with a mean age of 27. 3 years (range, 16 to 50 years). The visual acuity was light perception in 15 eyes, hand motions in 18 eyes, counting fingers in 6 eyes and 0. 02 to 0. 1 in 10 eyes before vitrectomy. Visual acuity improved postoperatively in all eyes with PVH, NVD of NVP with a mean visual acuity of 0. 32 (range,0. 05 to 1. 0,n = 28) except 3 eyes unchanged There was no significant difference ( P > 0. 05 ) in the patien 相似文献

Studies on vitrectomy cases associated with complicated branch retinal vein occlusion 总被引:4,自引:0,他引:4
PURPOSE: To study the preoperative factors leading to vitrectomy, and to demonstrate the postoperative conditions causing the decreased visual acuity that results from branch retinal vein occlusion (BRVO). METHODS: In 113 patients (114 eyes) with BRVO, the following data were analyzed: age, general complications, distribution of occluding vessels, location of retinal breaks, classification of vitreoretinal pathology, and the number of cases, period from onset of BRVO to vitreous hemorrhage and from vitreous hemorrhage to vitrectomy, number of operations, relationship between posterior vitreous detachment (PVD) and number of operations, preoperative photocoagulations, pre- and postoperative visual acuity, and cases with poor visual outcome. RESULTS: The visual prognosis was much better in cases with vitreous hemorrhage only than in those with proliferative membrane and retinal detachment (P =.0023). Repeated surgeries were needed in the cases where there was only partial PVD (P =.0029). Macular disorders and optic nerve atrophy were the main causes of postoperative visual acuity < 0.1. CONCLUSIONS: Early vitrectomy before development of vitreo retinal proliferation and retinal detachment, especially in cases where there is only partial PVD, seems to be essential for case management and treatment to attain better visual acuity for the patient. 相似文献

In order to study long-term anatomical and functional results the authors evaluated the data from 260 patients who underwent pars plana vitrectomy for proliferative diabetic retinopathy. Indications for surgery were: vitreous hemorrhage, 68 eyes (26.2%); vitreous hemorrhage & tractional retinal detachment, 84 eyes (32.3%); tractional retinal detachment, 82 eyes (31.5%); and combined tractional-rhegmatogenous retinal detachment, 26 eyes (10%). In 118 eyes vitreoretinal surgery was combined with silicone-oil tamponade.The retina was completely attached posterior to a scleral buckle in 251 eyes (96%) at the time of the last examination. After a follow-up period of at least 12 months in a group of patients with vitreous hemorrhage, visual acuity improved in 88% of the eyes. Visual acuity was better than 0.5 in 31% of eyes. In group of eyes with nonresorbing vitreous hemorrhage & tractional retinal detachment visual acuity improved in 52% of eyes. Visual acuity improved in 76% of eyes with tractional retinal detachment and in 81% of eyes with combined tractional & rhegmatogenous retinal detachment. When comparing the latest postoperative visual acuity to visual acuity after three months postoperatively, visual acuity was unchanged in 88%, in 10% it became worse and in 3 cases (1%) became better. In the postoperative period, recurrent vitreous hemorrhage occurred in 33 (13%) eyes, reproliferation in 12 eyes.Cataract developed in 45 of 168 phakic eyes. If postoperative visual acuity before cataract formation was good, extracapsular cataract extraction with posterior chamber intraocular lens implantation was performed. Otherwise simple intra or extracapsular cataract extraction was performed. In 19 cases cataract operation was performed together with silicone oil extraction. Neovascular glaucoma developed postoperatively in 15 eyes (6%). Retinal detachment occurred postoperatively in 21 eyes (8%). In 15 eyes the retina was successfully reattached after additional operations. 相似文献

Forty-nine consecutive eyes with nonclearing vitreous hemorrhage not associated with retinal or choroidal vascular disease underwent vitrectomy. Etiologies included vitreous hemorrhage during anterior segment surgery (22 eyes), blunt trauma (8 eyes), retinal tears with and without retinal detachment (8 eyes), Terson's syndrome (2 eyes), avulsed retinal vessel (1 eye), and idiopathic cases (8 eyes). The final visual acuity improved in 48 eyes (98%). Follow-up was 6-91 months (mean, 20 months). Of the 49 eyes, 40 eyes (82%) had a best postoperative visual acuity of 20/100 or better, 31 eyes (63%) had visual acuity of 20/40 or better, and 12 eyes (24%) had visual acuity of 20/20. The major complications included intraoperative iatrogenic retinal breaks (5 eyes), postoperative progressive cataract (7 eyes), late retinal detachment (4 eyes) and recurrent vitreous hemorrhage (2 eyes). The major complication associated with later visual loss was progressive cataract. 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
