目的:观察玻璃体腔注射bevacizumab(Avastin)治疗视网膜分支静脉阻塞性黄斑水肿的有效性和安全性。方法:观察一组视网膜分支静脉阻塞引起黄斑水肿的连续病例,对其进行玻璃体腔注射bevacizumab(Avastin)后的疗效进行分析。所有患者在治疗开始前以及治疗后随诊时间点均进行完全的眼科相关检查,包括视力测定,OCT和/或FFA检查。结果:对32例患者(32眼)分别至少进行一次玻璃体腔注药(1～3次),术后平均观察时间为4.7mo。平均视力:治疗前为20/200-,治疗后1mo20/100-,治疗后3mo及最近一次检查为20/100+(P<0.01);黄斑中心1mm区厚度:治疗前为483μm,治疗后1,3mo及最近一次分别为275,314和301μm(P<0.01)。没有观察到任何不良副作用。结论:玻璃体腔注射bvacizumab(Avastin)治疗能显著减轻视网膜分支静脉阻塞性黄斑水肿、提高视力且没有不良反应。     

玻璃体腔注射bevacizumab治疗视网膜分支静脉阻塞继发黄斑水肿

目的：通过测量随访12mo后的中央黄斑厚度（CMT）和视力,评估玻璃体腔注射bevacizumab治疗视网膜分支静脉阻塞（BRVO）继发黄斑水肿（ME）的效果。方法：被诊断为BRVO继发ME的患者行眼科检查、CMT测量、荧光素血管造影。排除荧光素血管造影出现黄斑缺血患者,其他疾病继发的其他部位新生血管化患者,有眼内治疗史（激光治疗、玻璃体腔注射或眼科手术）患者。CMT 〉250μm的32例患者给予bevacizumab（Altuzan,0.125mg/0.05mL）注射治疗,并随访12mo。分析最佳矫正视力（BCVA）logMAR数据和CMT控制参数。使用Minitab15.0软件统计分析配对t检验,P〈0.05有统计学意义。结果： BCVA logMAR数据和CMT控制参数的平均值较注射前有明显改变（P〈0.01）。平均最佳矫正视力增量为0.477±0.235,平均CMT较注射前下降257.906±88.865。10例（31%）患者对单次注射有阳性反应,平均12.6±0.66mo未复发ME。5例（15.6%）患者接受两次注射,17例（53%）3次以上。单眼平均注射量2.18±0.91（1～4）。第一组ME复发时间为2.45±0.63mo,第二组为2.58±0.66mo,第三组为3.17±0.48mo。5例（15.6%）患者需要多次注射以减轻ME,视力并未随ME的减轻而增加。结论：玻璃体腔注射bevacizumab是常规治疗BRVO继发ME的方法,有效、快速、安全。为了使疗效持久,需加强后续处理,通过激光或长效药物保持无水肿状态。视网膜静脉循环和ME须通过荧光素血管造影观察,而不能采取频繁注射。是否需再次注射必须根据ME的临床表现和视力的预测来判断。

Intravitreal bevacizumab (Avastin) treatment of macular edema in central retinal vein occlusion: a short-term study

PURPOSE: To report the short term anatomic and visual acuity response after intravitreal injection of bevacizumab (Avastin, Genentech) in patients with macular edema due to central retinal vein occlusion (CRVO). METHODS: The authors conducted a retrospective study of patients with macular edema due to CRVO who were treated with at least one intravitreal injection of bevacizumab 1.25 mg in 0.05 mL. Patients underwent Snellen visual acuity testing, optical coherence tomography (OCT) imaging, and ophthalmoscopic examination at baseline and follow-up visits. RESULTS: There were 16 eyes of 15 consecutive patients with a mean age of 76.1 years (SD 9.8 years). Intravitreal triamcinolone had been previously administered to 9 patients, but all of these patients either had no improvement or had excessive intraocular pressure caused by the triamcinolone. The patients received a mean of 2.8 injections of bevacizumab per eye. No adverse events were observed, including endophthalmitis, clinically evident inflammation, increased intraocular pressure, retinal tears, retinal detachment, or thromboembolic events in any patient. The mean central macular thickness at baseline was 887 microm and decreased to a mean of 372 microm at month 1 (P < 0.001). The mean baseline acuity was 20/600 (logMAR = 1.48) and the mean acuity at month 1 was 20/200 (logMAR = 1.05), a difference that was highly significant (P = 0.001). At last follow-up, a mean of 3 months after the first injection, the mean visual acuity was 20/138 (logMAR = 0.84), which was significantly better than baseline (P < 0.001). Visual acuity improvement, defined as a halving of the visual angle, was seen in 14 of the 16 eyes. CONCLUSION: Initial treatment results of patients with macular edema secondary to CRVO did not reveal any short-term safety concerns. Intravitreal bevacizumab resulted in a significant decrease in macular edema and improvement in visual acuity. The number of patients in this pilot study was limited and the follow-up is too short to make any specific treatment recommendations, but the favorable short-term results suggest further study is needed.     

Intravitreal triamcinolone as primary treatment of cystoid macular edema secondary to branch retinal vein occlusion

PURPOSE: To describe six patients treated with intravitreal triamcinolone (IVT) as primary therapy for cystoid macular edema (CME) secondary to branch retinal vein occlusion (BRVO). METHODS: Retrospective case series. RESULTS: The age of the patients ranged from 53 years to 87 years (mean, 66 years). The time between BRVO and treatment with IVT ranged from 2.0 months to 4.7 months (mean, 3.5 months). Pretreatment visual acuity ranged from 20/40 to 6/200 (mean, 20/166). Length of follow-up ranged from 107 days to 175 days (mean, 149.5 days). Final visual acuity ranged from 20/40 to 3/200 (mean, 20/137). Three of six eyes showed improvement in vision. All three patients who did not have vision improvement were treated with a second injection. At the final follow-up visit, all six eyes had improved vision from baseline. Five (83.3%) of six eyes showed an improvement of > or = 2 lines of vision. One patient had a postoperative rise in intraocular pressure requiring a trabeculectomy. Final visual acuity in the 6 eyes ranged from 20/200 to 20/30 (mean, 20/106). CONCLUSION: IVT may be of potential use in treating CME due to BRVO, as either a primary or an adjunctive treatment modality. A prospective, randomized trial to clarify this role is warranted.

Intravitreal injection of bevacizumab combined with macular grid laser photocoagulation for macular edema in branch retinal vein occlusion

Purpose  

To evaluate the effects of combined therapy of intravitreal injections of bevacizumab (IVB) and additional macular grid laser photocoagulation for recurrent macular edema in branch retinal vein occlusion (BRVO).     

Intravitreal triamcinolone for cystoid macular edema related to branch retinal vein occlusion

We retrospectively evaluated the effectiveness of intravitreal triamciolone in treating 19 eyes with macular edema related to branch retinal vein occlusion (BRVO). Eyes with nonischemic BRVO respond more favorably than those with ischemic BRVO. A single injection of intravitreal triamcinolone led to elevated intraocular pressure in 3 of 19 eyes (16%). Half of phakic eyes had progression of cataract. Retreatment may be necessary.     

Intravitreal bevacizumab treatment of macular edema in central retinal vein occlusion: one-year results

Purpose To report on the anatomic and visual acuity response after intravitreal bevacizumab injection in patients with macular edema due to non-ischemic central retinal vein occlusion (CRVO). Methods In a retrospective study, 21 consecutive patients (21 eyes) with non-ischemic CRVO underwent, on average, 3.7 intravitreal bevacizumab injections (1.25 mg). Ophthalmic examination included best corrected visual acuity (BCVA) and central retinal thickness (CRT) at baseline and follow-up visits. Fluorescein angiography was performed at baseline and at follow-up visits if needed. Primary outcomes were change of BCVA and CRT. Results The follow-up period for all of the included patients was 12 months. The mean BCVA was unchanged at the 12-month examination (baseline: 20/160; 12 months: 20/160) (P = 0.771). The mean CRT decreased from 780 μm (standard deviation [SD] ± 324 μm) at the baseline to a mean of 462 μm (SD ± 248 μm) at 12 months (P < 0.05). Conclusion Intravitreal bevacizumab resulted in a significant decrease in CRT without significant improvement of visual acuity in patients with non-ischemic CRVO after a follow-up of 12 months.
