Purpose: To evaluate the effect of early intravitreal bevacizumab injections for the treatment of macular oedema caused by non‐ischaemic central retinal vein occlusion (CRVO). Methods: The study included 25 patients (25 eyes) with macular oedema caused by non‐ischaemic central retinal vein occlusion, who received three intravitreal injections of 1.5 mg bevacizumab with an interval of 6 weeks between the injections. Mean duration of central retinal vein occlusion prior to the first injection was 4.2 ± 3.6 days. All patients were re‐examined 1, 3 and 6 months after the first injection. The main outcome parameters were visual acuity and macular thickness, as measured by optical coherence tomography. Results: Mean visual acuity improved significantly from 0.97 ± 0.40 logMAR at baseline to 0.70 ± 0.42 logMAR ( P = 0.007) at 1 month, 0.69 ± 0.46 ( P = 0.006) 3 months and 0.69 ± 0.52 ( P = 0.015) 6 months after the first injection. Mean central retinal thickness decreased significantly from 530 ± 152 μm at baseline to 347 ± 127 μm ( P < 0.001) at 1 month, 370 ± 165 μm ( P < 0.001) 3 months and 346 ± 129 μm ( P < 0.001) 6 months ( P < 0.001) after the first injection. The increase in visual acuity correlated significantly ( P < 0.01) with the decrease in macular thickness. Mean intraocular pressure was 14.2 ± 3.2 mmHg at baseline and did not differ significantly from the measurement obtained at 1 month ( P = 0.59), 3 months ( P = 0.88) and 6 months after the first injection ( P = 0.65). Conclusion: Intravitreal bevacizumab injections given shortly after onset of non‐ischaemic central retinal vein occlusion may result in a significant increase in vision and a corresponding decrease in macular oedema. 相似文献

Objective: To evaluate the effect of intravitreal bevacizumab on visual acuity (VA) and central retinal thickness (CRT) in patients with macular edema (ME) secondary to branch retinal vein occlusion (BRVO). Design: Retrospective review. Participants: The study included 42 patients with ME secondary to BRVO who received intravitreal injections of bevacizumab in 2 referral-based retinal practices in Vancouver, B.C., between November 2005 and July 2006. Methods: We performed a retrospective review of consecutive patients with ME secondary to BRVO. All of the patients in this study had nonischemic BRVOs. Patients were all treated with at least 1 bevacizumab injection and were seen at 6- to 8-week intervals for VA testing. Most of the patients also underwent optical coherence tomography (OCT) 2 months and 6 months after treatment. VA and OCT measurements at each follow-up time point were compared with the baseline values. Results: A total of 42 eyes from 42 patients with ME secondary to BRVO were reviewed. The mean VA improved from 20/280 at baseline to 20/180 at first follow-up session ( p < 0.04; average follow-up = 42 days) and remained at a similar level, 20/170, through the eighth follow-up session ( p < 0.04; average follow-up = 356). The CRT was reduced from a mean of 451 μm (388-512 μm) at baseline to 358 μm (298-418 μm) at 2 months ( p < 0.02) and to 400 μm (335-465 μm) at 6 months postinjection ( p < 0.068). Conclusions: We found a significant improvement in VA and CRT in patients with ME secondary to BRVO after intravitreal bevacizumab injection(s). No complications or serious side effects were observed. Intravitreal bevacizumab appears to have an emerging role as either a primary or an adjuvant treatment modality in the setting of ME secondary to BRVO. 相似文献

Purpose: Choroidal neovascularization (CNV) accounts for 85–90% of severe visual impairment in age‐related macular degeneration (AMD). Vascular endothelial growth factor (VEGF) is a major factor mediating angiogenesis, and VEGF inhibitors have become a new treatment modality. In this prospective study, we used bevacizumab (Avastin ®), a recombinant monoclonal antibody to VEGF, to treat neovascular AMD. Methods: The case material comprised 36 subjects (26 females, 10 males) aged 65–88 years with subfoveal neovascular AMD with all subtypes of CNV. There were two categories of patients: category I, long‐standing CNV (12 months or more), preoperative visual acuity (VA) 0.16 (mean); category II, CNV (duration <12 months), preoperative VA 0.25 (mean). Evaluation protocol included the Early Treatment Diabetic Retinopathy Study (ETDRS) VA, clinical ophthalmological examination, fluorescein angiography and optical coherence tomography (OCT). Intravitreal injections of bevacizumab (Avastin ®) (IVB), 1.25 mg (0.05 ml), were given under an operating microscope and aseptic conditions in a theatre for surgery with intervals of 4 or 6 weeks during the first 3 months and subsequently according to clinical assessment. The follow‐up was 6 months in all cases. Results: At 6 months, mean VA had improved by 4.6 ETDRS letters in the entire case material ( P = 0.001), by 3.9 letters in category I (duration 12 months or more) and by 6.0 letters in category II (duration <12 months). A total of 148 IVB (mean 4.1 injections/eye) were delivered during 6 months, the first 3 months comprising 3.1 IVB (mean) and the last 3 months 1.0 IVB (mean). No eyes suffered visual decline of 15 ETDRS letters. Fluorescein angiograms displayed stabilization or regression of CNV activity; OCT showed resorption of intraretinal oedema and subretinal fluid. No severe complications occurred but recurrence was common, and repeated IVBs were necessary in most cases during the 6‐month period. Conclusion: When addressing the issue of frequency of IBV, we observed that 6‐week intervals were sufficient because VA and CNV lesions generally stabilized at 4 weeks. The gain in VA was promising in eyes with <12 months CNV duration. Even in eyes with a longer CNV duration, a slight visual improvement was observed when retinal oedema resorbed, although subretinal fibrosis and general cellular damage certainly limited recovery. 相似文献

AIM: To investigate the effects of two different doses of intravitreal bevacizumab on subfoveal choroidal thickness (SFChT) and retinal vessel diameter in patients with branch retinal vein occlusion.
METHODS: An interventional, restrospective study of 41 eyes of 41 patients who had completed 12mo of follow-up, divided into group 1 (1.25 mg of bevacizumab, 21 eyes of 21 patients) and group 2 (2.5 mg of bevacizumab, 20 eyes of 21 patients). Complete ophthalmic examination, fluorescein angiography, enhanced depth imaging optical coherence tomography and measurement of retinal vessel diameter with IVAN software were performed at baseline and follow-up.
RESULTS: The SFChT changed from 279.1 (165-431) µm at baseline to 277.0 (149-413) µm at 12mo in group 1 (P=0.086), and from 301.4 (212-483) µm to 300.3 (199-514) µm in group 2 (P=0.076). The central retinal arteriolar equivalent (CRAE) changed from 128.8±11.2 μm at baseline to 134.5±8.4 μm at 12mo in group 1, and from 134.6±9.0 μm to 131.4±12.7 μm in group 2 (P=0.767). The central retinal venular equivalent (CRVE) changed from 204.1±24.4 μm at baseline to 196.3±28.2 μm at 12mo in group 1, and from 205.8±16.3 μm to 194.8±18.2 μm in group 2 (P=0.019). The mean central macular thickness (P<0.05) and average best-corrected visual acuity (BCVA; P<0.05) improved in both groups
CONCLUSION: Changes in the SFChT are not statistically significant and not different according to the doses of bevacizumab. The CRAE did not show significant change, however, the CRVE showed significant decrease regardless of the dose. 相似文献

Purpose: To investigate the effectiveness of repeated injections of intravitreal triamcinolone acetonide (IVTA) in the treatment of macular oedema caused by central retinal vein occlusion (CRVO). Methods: Seventeen pseudophakic or aphakic eyes of 17 patients (10 male, seven female) with macular oedema caused by CRVO received a repeat injection of 4 mg IVTA, 16 weeks after the first injection of the same dose. The examination included measurements of best‐corrected visual acuity (BCVA) for distance and central foveal thickness (CFT) by optical coherence tomography (OCT), preoperatively and 1, 2, 3 and 4 months postoperatively. The values were compared by paired‐ t test. Side‐effects were monitored. Results: BCVA and CFT were not significantly different before initial and repeat injections. Transient improvements of BCVA and CFT were achieved after both injections. At the end of follow‐up, BCVA and CFT were significantly different compared to pre‐injection values in the same group ( P = 0.032, 0.049 in the initial‐injection group and P = 0.001, 0.008 in the repeat‐injection group, respectively). However, compared to the initial injection, BCVA measurements were significantly worse at each time‐point ( P = 0.043, 0.011, 0.010 and 0.012, respectively) after the repeat injection, as were CFT at 1, 2 and 3 months post‐injection ( P = 0.040, 0.015 and 0.025, respectively). The achieved maximum mean intraocular pressures were 20.00 [standard deviation (SD) 2.06] mmHg and 18.56 (SD 3.65) mmHg after the first and repeat injections, respectively. These values were not significantly different ( P = 0.467). No other significant adverse events were noted during the study. Conclusion: A repeat injection of 4 mg IVTA may not be as effective as an initial injection for the treatment of macular oedema caused by CRVO. 相似文献

Purpose: To compare the efficacy of intravitreal injections of triamcinolone acetonide (TA) and that of bevacizumab for macular oedema because of branch retinal vein occlusion (BRVO). Design: Prospective, comparative, randomized, interventional clinical trial. Methods: Forty‐three eyes of 43 patients with macular oedema because of BRVO were randomly assigned to 4‐mg intravitreal injections of TA (IVTA)(21 patients, IVTA group) or 1.25‐mg intravitreal injections of bevacizumab (IVB) (22 patients, IVB group) and followed for 12 months. No additional treatments were administered for 3 months after the initial injection; additional injections were administered when macular oedema recurred between 3 and 12 months after the initial injection. The best‐corrected visual acuity (BCVA) and the central retinal thickness (CRT) were measured at baseline and monthly. The main outcome measures were changes in the logarithm of the minimal angle of resolution BCVA and CRT from baseline to 12 months. Results: Eighteen eyes of 18 patients in the IVTA group and 18 eyes of 18 patients in the IVB group completed follow‐up at 12 months. The mean improvements in BCVA from baseline to 12 months were 0.12 in the IVTA group and 0.33 in the IVB group, which was significantly (p = 0.032) higher than in the IVTA group. There was no significant difference between the two groups in the mean reduction in CRT from baseline to 12 months after the initial injection. Two eyes in the IVTA group required intraocular pressure–lowering medications. Conclusion: Intravitreal injection of bevacizumab may be of greater benefit than that of TA for macular oedema because of BRVO. 相似文献

AIM:To compare the efficacy of ranibizumab and bevacizumab for macular edema due to retinal vein occlusion (RVO). METHODS:A retrospective study was conducted at a single academic institution. Eighty-one patients na?ve to anti-VEGF therapy with RVO and macular edema were identified. Twenty-six eyes were treated with ranibizumab, 33 eyes with bevacizumab, and 22 eyes with bevacizumab then switched to ranibizumab (crossover) . The main outcome was change in visual acuity at 3 months, 6 months, and final visit. RESULTS:The mean visual acuity improved from 20/80 to 20/40 in the ranibizumab (R) group and from 20/125 to 20/60 in the bevacizumab (B) group ( P=0.66). The mean change in central subfield thickness (CST) was -186 and -212μm, respectively ( P=0.69). Mean time between injections was 94±21.1d in the R group and 103.8±10.5d in the B group ( P=0.78). In the crossover group, mean initial visual acuity was 20/125, reached 20/60 at crossover, and remained 20/60 at conclusion ( P=0.91). CONCLUSION:Both ranibizumab and bevacizumab are effective for the treatment of RVO and appear to have similar visual and anatomic outcomes . Changing treatments from bevacizumab to ranibizumab did not result in further gains in visual acuity . 相似文献

Purpose:To evaluate the effect of intravitreal triamcinolone acetonide (IVTA) on retinal sensitivity in cases of macular edema(ME) secondary to branch retinal vein occlusion (BRVO). Materials and Methods:Total of 14 eyes of 14 cases of BRVO were included in this prospective study. In each eye, at baseline and 1, 3, and 6 months after IVTA injection, logMAR visual acuity, central 4° retinal sensitivity by MP-1 microperimetry, and optical coherence tomography foveal thickness were assessed. Results:Cases ages ranged from 60 to 79 years (mean 68 ± 8 years). At 1, 3, and 6 months, the logMAR visual acuity had increased from 0.71 ± 0.21 to 0.42 ± 0.21, 0.46 ± 0.30, and 0.46 ± 0.27; the mean foveal thickness had decreased from 540 ± 88 μm to 254 ± 51 μm, 288 ± 84 μm, and 280 ± 91 μm; and the mean retinal sensitivity had increased from 4.7 ± 2.5 dB to 7.9 ± 2.7 dB, 8.2 ± 3.6 dB, and 8.3 ± 4.6 dB, respectively. Conclusion:In eyes with ME secondary to BRVO, IVTA injections result in a significant increase in not only the visual acuity but also the central 4° retinal sensitivity in 6 months follow-up. 相似文献

Purpose:To evaluate the efficacy of combined treatment with intravitreal bevacizumab (IVB) and triamcinolone acetate (IVT) for patients with macular edema secondary to branch retinal vein occlusion (BRVO). Materials and Methods:Retrospective analysis of 20 eyes injected with 1.25 mg IVB and 2 mg IVT for clinically identified BRVO within 8 weeks of onset. All patients lacked concomitant ocular pathology and completed 6 months’ follow-up. Clinical examination including LogMAR visual acuity (VA) and central macular thickness (CMT) by spectralis optical coherence tomography (OCT) was performed preoperatively and at 1, 3 and 6 months post-operatively. Results:Mean patient age was 61.3 years with a mean BRVO diagnosis time of 3 weeks at presentation. VA improved from logMAR 1.08 preoperatively to Mean logMAR VA of 0.55 ± 0.17 at 1 month ( P < 0.001), 0.56 ± 0.21 at 3 months ( P < 0.001), and 0.38 ± 0.1 at 6 months ( P < 0.001) Mean CMT improved from 482 ± 107 μm preoperatively to 319 ± 53 μm at 1 month ( P < 0.001), 344 ± 89 μm at 3 months ( P < 0.001), and 241 ± 29 μm at 6 months ( P < 0.001). Mean IOP preoperatively was 16.5 mmHg, 21 mmHg at 1 month, and 15 mmHg at 6 months. Six out of 20 patients (30%) were re-injected with IVB and IVT at 3 months. Conclusions:Early combined treatment with IVB and IVT is effective in improving anatomic and functional outcomes in patients with macular edema secondary to BRVO. 相似文献

视网膜中央静脉阻塞是仅次于糖尿病性视网膜病变的常见视网膜血管病,常导致视力下降甚至失明,以往视网膜激光光凝术、手术、玻璃体腔注药等疗法对视网膜中央静脉阻塞的治疗有一定疗效,近年来一些新方法如抗新生血管内皮生长因子、地塞米松缓释剂以及联合治疗等的出现,取得较好效果,但更安全有效的治疗措施有待进一步研究. 相似文献

视网膜静脉阻塞( retinal vein occlusion,RVO) 是继糖尿病性视网膜病变之后最常见的影响视网膜的视觉致残性疾病。虽然该疾病实体早已被认定,但其治疗仍存在争议。黄斑水肿是该视网膜血管性疾病中视力下降 ( visual acuity,VA) 的主要原因。最近玻璃体腔已越来越多地被用来作为一个药物储物,通过玻璃体腔注射直接治疗黄斑水肿。迄今最广泛的注射药物为曲安奈德( triamcinolone acetonide,TA) 和贝伐单抗。该论文的目的是评估证据,并讨论最近有人提出的关于玻璃体内注射皮质类固醇和抗血管内皮生长因子的药物治疗对视网膜静脉阻塞是有效的基本原理。 相似文献

Retinal vein occlusion (RVO) is the most common visually disabling disease affecting the retina after diabetic retinopathy. Although the disease entity has long been known, its management is still controversial. Macular edema is the main reason for decreased visual acuity (VA) in this retinal vascular disorder. Recently the vitreous cavity has increasingly been used as a reservoir of drugs for the direct treatment of macular edema through intravitreal injection route. The most widely injected drugs so far have been triamcinolone acetonide (TA) and bevacizumab. The objective of this review is to evaluate the evidence and discuss the rationale behind the recent suggestions that intravitreal pharmacotherapy by corticosteroids and anti-vascular endothelial growth factors may be useful in the treatment of retinal vein occlusion. 相似文献

目的 观察玻璃体内注射贝伐单抗治疗视网膜中央静脉阻塞(central retinal vein occlusion,CRVO)继发黄斑水肿患者的临床特征及疗效,探讨对短期黄斑水肿恢复有影响的因素。方法 回顾性分析60例60眼CRVO继发黄斑水肿患者,采用玻璃体内注射贝伐单抗1.25 mg(0.05 mL),必要时重复治疗,随访3个月观察患者最佳矫正视力(best-corrected visual acuity,BCVA)及黄斑中心视网膜厚度(central retinal thickness,CRT)改变。根据治疗后3个月时CRT恢复水平,分析患者的年龄、病程、基线视力、基线CRT、高血压及糖尿病、黄斑囊样水肿(cystoid macular edema,CME)或视网膜下液体(subretinal fluid,SRF)情况对黄斑水肿恢复的影响。结果 BCVA从基线(0.897±0.395)LogMAR提高到治疗后1个月的(0.616±0.350)LogMAR,并稳定持续至治疗后3个月(P<0.001),同时CRT从基线(721.2±180.8)μm降低到治疗后3个月的(392.1±185.4)μm(P<0.001)。治疗后3个月56.7%的CME和超过90%的SRF均得到完全缓解。年龄和基线CRT低提示治疗后3个月时CRT恢复较好(P=0.036、0.037)。年龄大的患者(>60岁)治疗后黄斑水肿消除更多(P=0.031),治疗后3个月时CRT更低(P=0.003)。结论 玻璃体内注射贝伐单抗能有效提高BCVA并降低CRT。年龄大和基线CRT低提示治疗后3个月时CRT恢复较好。CRT的降低主要取决于CME是否消除,而与SRF无关。 相似文献
