Intravitreal bevacizumab for the management of choroidal neovascularization in age-related macular degeneration

PURPOSE: To investigate the efficacy and safety of intravitreal bevacizumab for managing choroidal neovascularization (CNV) due to age-related macular degeneration (AMD). DESIGN: Prospective interventional case series. METHODS: Seventeen eyes of 17 patients with subfoveal CNV due to AMD participated in this study at the American University of Beirut Ophthalmology Clinics. All patients had failed, refused, or were not eligible for photodynamic therapy. All eyes received a baseline eye examination, which included best-corrected visual acuity (BCVA), dilated fundus examination, ocular coherence tomography (OCT) imaging, and fluorescein angiography. An intravitreal injection of bevacizumab (2.5 mg/0.1 ml) was given at baseline and followed by two additional injections at four-week intervals. BCVA, OCT, and fluorescein angiography were repeated four weeks after each injection. Main outcome measures were improvement in BCVA and central retinal thickness (CRT). RESULTS: Mean baseline BCVA was 20/252 (median 20/200), and baseline CRT was 362 microm (median 350 microm). Improvement in VA and CRT occurred by the fourth week. At 12 weeks, mean BCVA was 20/76 (P < .001) and median BCVA was 20/50 (P < .001). Both mean and median CRT decreased to 211 microm (P < .001). Thirteen (76%) of 17 eyes had total resolution of subretinal fluid, and four eyes (24%) had BCVA better than 20/50. No systemic or ocular side effects were noted at any time. CONCLUSION: Eyes with CNV due to AMD treated with intravitreal bevacizumab had marked anatomic and visual improvement. Further studies are necessary to confirm the long-term efficacy and safety of this treatment.     

Intravitreal bevacizumab for idiopathic choroidal neovascularization after previous injection with posterior subtenon triamcinolone

PURPOSE: To assess short-term efficacy and safety of intravitreal bevacizumab injections for idiopathic choroidal neovascularization (CNV) refractory to posterior subtenon triamcinolone injections. DESIGN: Noncomparative, interventional case series. METHODS: Intravitreal bevacizumab was injected into 10 eyes with idiopathic CNV in which posterior subtenon triamcinolone injections were not efficacious for more than three months. The main outcome measures were changes in best-corrected visual acuity (BCVA), central retinal thickness (CRT), and fluorescein angiography findings before and after bevacizumab injection. RESULTS: After treatment, the BCVA improvement at one month (P = .029) continued to three months (P = .003). CRT decreased significantly (P < .001). Leakage from idiopathic CNV three months after treatment stopped in seven eyes, decreased in two, and continued in one. In one patient, conjunctival swelling developed after the injection but resolved and did not recur after another injection. No other complications developed. CONCLUSIONS: Intravitreal bevacizumab improves BCVA in eyes with idiopathic CNV refractory to triamcinolone.     

Intravitreal bevacizumab combined with photodynamic therapy for the treatment of occult choroidal neovascularization associated with serous pigment epithelium detachment in age-related macular degeneration

PURPOSE: To evaluate the efficacy of intravitreal injection of bevacizumab combined with photodynamic therapy (PDT) for the treatment of occult choroidal neovascularization (CNV) associated with serous pigment epithelium detachment (s-PED) due to age-related macular degeneration (AMD). METHODS: In this retrospective study, six patients (six eyes) with subfoveal occult CNV associated with s-PED due to AMD were treated with intravitreal bevacizumab combined with PDT. All patients were treated at baseline with PDT followed by intravitreal bevacizumab 1.25 mg 1 hour later. Afterwards, according to the findings of optical coherence tomography and fluorescein angiography, repeat bevacizumab injections were given, if necessary, monthly for three doses followed by further doses every 3 months. PDT was repeated every 3 months according to the same criteria. Follow-up time was 9 months. RESULTS: All patients completed their treatment during the first 3 months from baseline. Best-corrected visual acuity (BCVA) improved or remained stable related to the baseline values in all patients at the end of the follow-up time. Mean BCVA improved from 20/67 to 20/42. S-PED and subretinal fluid decreased or disappeared. The mean central 1-mm retinal thickness was reduced from baseline value for the 9-month follow-up period by 128 microm. CONCLUSION: Intravitreal bevacizumab combined with PDT seems to be a promising treatment with good functional and anatomical results for occult CNV associated with s-PED due to AMD.     

Intravitreal bevacizumab (Avastin) treatment of neovascular age-related macular degeneration

PURPOSE: To report the change in visual acuity and central retinal thickness by optical coherence tomography (OCT) after intravitreal injections of bevacizumab for the treatment of neovascular age-related macular degeneration (AMD). METHODS: A retrospective case series in a university-based practice evaluated patients with subfoveal choroidal neovascularization (CNV) due to AMD. Patients received intravitreal injections (1.25 mg) of bevacizumab and were monitored monthly with determination of best-corrected ETDRS visual acuity and OCT for persistence of retinal thickening. Eyes were retreated on an "as needed" basis, defined by presence of intraretinal or subretinal fluid. Patients were monitored every 2 months to 3 months for persistence of angiographic leakage. RESULTS: Seventy-nine eyes of 74 consecutive patients received the initial injection of bevacizumab between August 1, 2005, and January 30, 2006. Sixty-eight eyes (86%) of 64 patients had at least 3 months of follow-up. Mean central retinal thickness +/- SD decreased from 304 +/- 83 microm at baseline to 237 +/- 105 microm at 3 months (P = 0.00002). Mean ETDRS visual acuity gained 4 letters from 20/100 at baseline to 20/80-1 at 3 months (P = 0.040). Twenty eyes (25%) appeared to have a sustained response to a single injection and did not require further injections through 3 months. Two patients had a potentially drug-related adverse event (ischemic stroke and myocardial infarction). No serious injection-related adverse events occurred. CONCLUSIONS: Intravitreal bevacizumab injection affects a rapid decrease in retinal thickness to normal or near-normal levels and improvement in visual acuity in eyes with CNV due to AMD. The sustainability of changes in retinal thickness and visual acuity in response to bevacizumab treatment warrant further investigation and long-term follow-up.     

Prognostic factors for visual outcome after intravitreal bevacizumab for macular edema due to branch retinal vein occlusion

PURPOSE: To evaluate the prognostic factors for visual outcome after intravitreal bevacizumab injection to treat macular edema due to branch retinal vein occlusion (BRVO). METHODS: Fifty eyes of 50 consecutive patients treated with intravitreal bevacizumab for macular edema due to BRVO with minimum follow-up of 3 months were retrospectively reviewed. Patients were categorized into two groups according to the final visual acuity. Group 1 consisted of eyes with 5 or more ETDRS letters gain, and group 2 consisted of eyes with less than 5 letters improvement or which had worsened at last follow-up visit. Comparative clinical and fluorescein angiographic characteristics were analyzed between the two groups. RESULTS: Of 50 eyes, 28 (56%) had improved vision after intravitreal bevacizumab injections and were categorized as group 1; 22 eyes (44%) were categorized as group 2. The number of early VA gainers, who showed visual improvement at 1 month after bevacizumab injection, was significantly higher in group 1 (P < 0.001, chi-square test). The early gainers tend to maintain significantly better visual outcome until last follow-up. The number of eyes with angiographically documented macular ischemia was significantly higher in group 2 (P < 0.001). In group 2, the decrease in central macular thickness was not accompanied by visual acuity improvement. CONCLUSION: Preoperative presence of macular ischemia can be useful in predicting the outcome of visual acuity after intravitreal bevacizumab for macular edema due to BRVO. The early gainers who favorably responded to the initial intravitreal bevacizumab injection are most likely to benefit from the bevacizumab treatment.     

Single-session photodynamic therapy combined with intravitreal bevacizumab for neovascular age-related macular degeneration

PURPOSE: To evaluate the efficacy of combined single-session photodynamic therapy (PDT) and intravitreal bevacizumab (IVB) for treatment of neovascular age-related macular degeneration (AMD). METHODS: In a prospective interventional case series, patients with subfoveal choroidal neovascularization (CNV) underwent PDT followed by 1.25 mg IVB injection. Best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) measurements were repeated at 6-week intervals and fluorescein angiography was performed after 12 weeks and when considered necessary thereafter. Repeat injections of IVB were performed based on fluorescein angiographic evidence of CNV leakage. RESULTS: Fourteen eyes were included in this study. Mean follow-up was 52.4+/-15.2 weeks (range: 26-74 weeks). Initially, mean BCVA was 0.80+/-0.42 logMAR and mean central macular thickness (CMT) was 308+/88 microm. At week 12, BCVA improved to 0.62+/-0.47 logMAR (p=0.006) and CMT reduced to 186+/-53 microm (p=0.003). Corresponding results were 0.53+/-0.52 logMAR (p=0.02) and 193+/-78 microm (p=0.002) after 24 weeks. A second IVB injection was performed in 13 eyes with a mean interval of 16.3+/-5.9 weeks. CONCLUSIONS: Combination therapy with single-session PDT and IVB can improve vision and reduce CMT in neovascular AMD. Repeat IVB injections may maintain the visual gain from the initial combination therapy.

Intravitreal bevacizumab (avastin) for central and hemicentral retinal vein occlusions: IBeVO study

PURPOSE: To evaluate the safety, visual acuity changes, and morphologic effects associated with intravitreal bevacizumab injections for the management of macular edema due to ischemic central or hemicentral retinal vein occlusion (RVO). METHODS: In this prospective, open-label study, 7 consecutive patients (7 eyes) with macular edema associated with ischemic central or hemicentral RVO were treated with intravitreal injections of 2.0 mg (0.08 mL) of bevacizumab at 12-week intervals. Standardized ophthalmic evaluation was performed at baseline and at weeks 1, 6, and 12 after each injection. Clinical evidence of toxicity and complications as well as changes in logarithm of minimum angle of resolution Early Treatment Diabetic Retinopathy Study best-corrected visual acuity (BCVA), central macular thickness (CMT) and total macular volume (TMV) shown by optical coherence tomography (OCT), and dye leakage shown by fluorescein angiography were evaluated. RESULTS: The median age of the 7 patients was 65 years (range, 58-74 years), and the median duration of symptoms before injection was 7 months (range, 2.5-16 months). At baseline, mean BCVA was 1.21 (Snellen equivalent, approximately 20/320) in the affected eye. Mean baseline CMT and TMV were 730.1 microm and 17.1 mm(3), respectively. Fluorescein leakage was observed in the macula and affected retinal quadrants in all seven eyes. Six patients completed the 25-week follow-up examination with reinjections performed at weeks 12 and 24. The most common adverse events were conjunctival hyperemia and subconjunctival hemorrhage at the injection site. At the last follow-up, mean BCVA in the affected eye was 0.68 (Snellen equivalent, 20/100(+1). No patient had a decrease in BCVA. Mean CMT and TMV at the 25-week follow-up were 260.3 microm and 9.0 mm(3), respectively; fluorescein leakage within the macula and affected retinal quadrants as compared with baseline was markedly reduced in all patients. Coupled with fluorescein angiographic findings, OCT data suggest a trend of macular edema recurrence between 6 weeks and 12 weeks after injection. CONCLUSIONS: Intravitreal bevacizumab injections of 2.0 mg at 12-week intervals were well tolerated and were associated with short-term BCVA stabilization or improvement and favorable macular changes in all patients with ischemic RVO and associated macular edema.     

Intravitreal bevacizumab for subfoveal choroidal neovascularization secondary to age-related macular degeneration in an Indian population

Purpose To investigate the 6-month safety profile and clinical outcomes of intravitreal bevacizumab for treating subfoveal choroidal neovascularization (CNV) in age-related macular degeneration (AMD). Methods We performed a prospective nonrandomized interventional study of 40 consecutive patients (40 eyes) with subfoveal CNV due to AMD. Patients underwent standard ophthalmic examination, optical coherence tomography, and fundus fluorescein angiography. All patients were administered one or more intravitreal injections of bevacizumab (1.25 mg) as primary therapy. Outcomes were also analyzed in subgroups based on lesion type (classic or occult) and lesion size (≤3000 μm or >3000 μm). Results At the 6 months’ follow-up, mean best-corrected visual acuity (BCVA) improved from 20/160 to 20/100 (P = 0.014), and the mean contrast sensitivity improved from 0.38 to 0.62 (P = 0.001). The mean greatest linear diameter and mean central macular thickness significantly decreased from 3.79 mm to 2.4 mm (P = 0.0001) and from 438.5 μm to 363 μm (P = 0.0001), respectively. Visual acuity gain of 15 letters or more was seen in 20% of patients, and the gain was more in the small-lesion subgroup (31.5%) than in the large-lesion subgroup (9.5%). No significant adverse effects were observed. Conclusion Intravitreal bevacizumab is a safe and effective modality for treatment of CNV secondary to AMD. A significant improvement in BCVA with intravitreal bevacizumab was observed for all lesion types.

Triamcinolone and PDT to treat exudative age-related macular degeneration and submacular hemorrhage

PURPOSE. To evaluate the efficacy of photodynamic therapy (PDT) with verteporfin and intravitreal injection of triamcinolone to treat choroidal neovascularization (CNV) with flat sub-macular hemorrhage in age-related macular degeneration (ARMD). METHODS. A prospective, consecutive, noncomparative, interventional case series study was performed at the Instituto Oftalmologico de Alicante, Spain. Ten consecutive eyes from 10 patients with flat submacular hemorrhage secondary to ARMD were treated by PDT followed by intravitreal injection of 19.4+/-2.1 mg/0.1 mL triamcinolone 5 days later. PDT was repeated if leakage from the CNV appeared on fluorescein angiography (FA) at 3 months follow-up intervals. Main outcome measures were best-corrected visual acuity (BCVA) before and after treatment, post-treatment FA, results, and complications. RESULTS. Stable or improved BCVA was achieved in seven eyes at 6 months follow-up. Complete absence of leakage in FA was observed in five and in eight eyes at 3 and 6 months follow-up, respectively. Intraocular pressure rose in seven eyes. CONCLUSIONS. PDT followed by intravitreal triamcinolone seems useful to treat CNV with flat submacular hemorrhage in ARMD. However, further studies with longer follow-up and randomized controlled trials are necessary to assess its efficacy in the management of this difficult clinical problem.

Arteriovenous sheathotomy for persistent macular edema in branch retinal vein occlusion

PURPOSE: To evaluate the efficacy of arteriovenous (AV) sheathotomy with internal limiting membrane peeling for persistent or recurrent macular edema after intravitreal triamcinolone injection and/or laser photocoagulation in branch retinal vein occlusion. METHODS: Twenty-two eyes with branch retinal vein occlusion (BRVO) with recurrent macular edema underwent vitrectomy with AV sheathotomy and internal limiting membrane peeling. All eyes had previous intravitreal triamcinolone injection and/or laser photocoagulation for macular edema. The best corrected visual acuity (BCVA), fluorescein angiography and optical coherence tomography (OCT) before and after surgery were compared. RESULTS: The mean preoperative BCVA (log MAR) were 0.79 +/- 0.29 and postoperative BCVA (log MAR) at 3 months was 0.57 +/- 0.33. And improvement of visual acuity > or = 2 lines was observed in 10 eyes (45%). The mean preoperative fovea thickness measured by OCT was 595.22 +/- 76.83 microm (510-737 microm) and postoperative fovea thickness was 217.60 +/- 47.33 microm (164-285 microm). CONCLUSIONS: Vitrectomy with AV sheathotomy can be one treatment option for the patients with recurrent macular edema in BRVO.

抗VEGF药物玻璃体内注射治疗视网膜血管样条纹继发脉络膜新生血管的远期观察

目的 探讨视网膜血管样条纹继发脉络膜新生血管(choroidal neovascularization,CNV)抗VEGF治疗的远期疗效.方法 回顾分析接受玻璃体内注射抗VEGF药物的视网膜血管样条纹继发CNV患者,观察至少3 a后患者视力改善情况、视网膜及脉络膜活动性病灶消退情况等指标.结果 纳入分析的21例(30眼)患者中,眼内注射次数6 ～18(10.0±2.4)次.随访36 ～54(39.5±2.2)个月.患者首次接受治疗时BCVA为(31.00±3.81)个字母数,观察终点时最佳矫正视力为(34.00±0.35)个字母数,总体差异无统计学意义(P=o.600).患者治疗前视网膜中央厚度为(406.21±21.23) μm,随访终末时为(251.16±36.36)μm,减少值为(150.21±24.43).μm,治疗前后视网膜中央厚度比较差异有统计学意义(P =0.002).30眼中16眼在初期治疗后视力明显提升,但随访中出现病变复发活跃后视力再次下降至基线水平;10眼在病变过程中出现不同程度黄斑下萎缩及瘢痕化改变,随访过程及随访终末视力与基线视力差异均无统计学意义(均为P ＞0.05);4眼由于初始CNV未累及黄斑区,在治疗随访过程中CNV稳定.结论 由于病变的高复发性及强活跃性,抗VEGF药物治疗血管样条纹继发CNV远期预后并不理想,治疗仅发挥了一定维持视功能的作用.     

Intravitreal injection of bevacizumab combined with verteporfin photodynamic therapy for choroidal neovascularization in age-related macular degeneration

PURPOSE: To report the outcome for eyes treated with intravitreal injection of bevacizumab combined with verteporfin photodynamic therapy (PDT) for choroidal neovascularization (CNV) in age-related macular degeneration (AMD). STUDY DESIGN AND PARTICIPANTS: Interventional, consecutive, retrospective case series including 40 eyes of 40 patients with newly diagnosed juxtafoveal or subfoveal CNV secondary to AMD. METHODS: The charts of patients treated with a 1.25-mg intravitreal injection of bevacizumab followed by PDT within a 2-week period were reviewed. Main outcome measures were visual acuity stabilization (defined as no change or a gain in visual acuity) and need for retreatment. RESULTS: Thirty-three (83%) of 40 eyes had stabilization of visual acuity. Mean improvement in visual acuity was 1.73 lines. Twenty-six eyes (65%) required only a single intravitreal injection of bevacizumab combined with PDT. Of the 23 eyes with 12 months of follow-up, 17 (74%) had stabilization of visual acuity, while 9 (40%) had improvement in visual acuity (mean, 1.22 Snellen lines). Eleven eyes (48%) required only a single combined treatment for CNV resolution at the 12-month follow-up. Fifteen (88%) of 17 eyes with only 6 months of follow-up required only a single combined treatment. There were no complications such as endophthalmitis, uveitis, or ocular hypertension. CONCLUSION: These findings suggest that eyes treated with both intravitreal injection of bevacizumab and PDT require none to a minimal number of re-treatments to have stabilization of vision, even at 12 months of follow-up. Further investigation with large controlled trials is warranted to outline the appropriate treatment paradigm for combination therapy.     

Intravitreal bevacizumab (avastin) for choroidal neovascularization secondary to central serous chorioretinopathy, secondary to punctate inner choroidopathy, or of idiopathic origin

PURPOSE: To evaluate the safety and efficacy of intravitreal bevacizumab in the treatment of idiopathic choroidal neovascularization (CNV) and CNV secondary to central serous chorioretinopathy (CSC) or punctate inner choroidopathy (PIC). DESIGN: Prospective, nonrandomized, interventional case series. METHODS: In an institutional clinical practice, 15 patients were recruited; nine had idiopathic CNV, two had CNV secondary to CSC, and four had CNV attributable to PIC. Patients received three monthly 1.25-mg intravitreal bevacizumab injections for three months. Patients were followed for six months, and the best-corrected visual acuity (BCVA), fluorescein angiography (FA) findings, and optical coherence tomography (OCT) central foveal thickness (CFT) were assessed. RESULTS: At baseline, the mean logMAR BCVA was 0.48 (Snellen equivalent = 20/60). The mean logMAR BCVA improved significantly to 0.25 (Snellen equivalent = 20/36) and 0.17 (Snellen equivalent = 20/30) at one and six months, respectively (both P = .001). The mean OCT CFT reduced from 306 microm at baseline to 201 microm at six months (P < .001). All eyes (100%) had visual improvement of 1 line or more at six months, and 11 (73.3%) improved by 2 or more lines. FA showed absence of CNV leakage, the angiographic end point, at three months, and no recurrence was observed at six months in all eyes. No systemic or ocular adverse events were encountered. CONCLUSIONS: Intravitreal bevacizumab injections resulted in visual and anatomic improvements in eyes with idiopathic CNV and CNV attributable to CSC or PIC. Further studies are warranted to assess the long-term safety and the regimen for optimal efficacy of intravitreal bevacizumab.     

Intravitreal bevacizumab therapy for choroidal neovascularization secondary to age-related macular degeneration: 6-month results of an open-label uncontrolled clinical study

PURPOSE: To investigate the 6-month safety and clinical outcomes of intravitreal injections of bevacizumab administered to treat choroidal neovascularization secondary to age-related macular degeneration. METHODS: Twenty-seven patients underwent 1.25 mg intravitreal injections of bevacizumab at baseline. A similar intravitreal injection was administered to all eyes at 1 and 2 month follow-up visits. At baseline and at each follow-up visit (1, 2, 3, and 6 months), patients underwent best-corrected visual acuity (BCVA) measurement, fluorescein angiography, indocyanine green angiography, and optical coherence tomography. Laboratory testing, visual field analyses, and endothelial cell counts were performed at baseline and third and sixth months. RESULTS: At 3 months, the mean BCVA remained substantially stable at 20/100. Mean central retinal thickness (CRT) decreased from 373 to 279 microm (p<0.01). Mean lesion greatest linear dimension (GLD) decreased from 4087 to 3782 microns (p<0.01). At 6 months, mean BCVA slightly decreased from 20/100(-1) to 20/125(-3) (not significant, p=0.40). Mean CRT was still inferior to baseline (305 microm, p<0.01). Mean lesion GLD was 4186 microm, not different from baseline values (p=0.59), but superior to 3-month mean GLD (p<0.01). Significant visual field defects or endothelial cell losses were not detected at 3 and 6 months. Laboratory testing did not reveal any clinically significant deviations compared to baseline values. CONCLUSIONS: Intravitreal therapy using bevacizumab over 6 months showed stabilization of visual acuity and choroidal neovascularization activity; the safety data were convincing.     

Intravitreal bevacizumab in inflammatory ocular neovascularization

PURPOSE: To assess the role of bevacizumab in inflammatory ocular neovascularization. DESIGN: Retrospective, multicenter, consecutive case series of inflammatory ocular neovascularization. METHODS: Patients with inflammatory ocular neovascularization of varying causes for whom standard therapy failed were treated with intravitreal injection of bevacizumab. Main outcome measures included improvement of best-corrected visual acuity (BCVA) expressed in logarithm of minimum angle of resolution units, response of inflammatory ocular neovascularization by funduscopy and angiography, and decrease in central foveal thickness as measured by optical coherence tomography at the three-month follow-up. RESULTS: At the three-month follow-up, 84 eyes of 79 patients had been treated with a mean of 1.3 injections (range, one to three). Thirty-four eyes showed juxtafoveal choroidal neovascularization (CNV), 34 eyes showed subfoveal CNV, eight eyes showed peripapillary CNV, and 11 eyes showed neovascularization of the disc (NVD) or neovascularization elsewhere (NVE). BCVA improved 2.4 lines from 0.68 (6/28 or 20/94) to 0.44 (6/17 or 20/55) (P < .001). BCVA improved by one to three lines in 34.5% of the eyes, by four to six lines in 16.7% of the eyes, and by more than six lines in 14.2% of the eyes. Function was unchanged in 23.8% of the eyes. BCVA worsened in 10.7% (zero to three lines in 7.1%, more than four lines in 3.6%). Central foveal thickness decreased from baseline 346 to 252 microm (P < .001). For CNV, 32 eyes (43.2%) had complete regression after the injection, 27 (36.5%) had partial regression, five (6.8%) had no response, and 10 eyes (13.5%) were not evaluated by the contributors. For NVD or NVE, seven eyes (63.6%) had complete regression of new vessels and four eyes (36.4%) had partial regression after the injection. CONCLUSIONS: Intravitreal bevacizumab led to short-term significant visual improvement and regression of inflammatory ocular neovascularization in a wide variety of inflammatory ocular diseases.
