Background: Age related macular degeneration (ARMD ) is the major cause of severe visual loss in older adults.Different treatment modalities are available such as: Laser photocoagulation,photodynamic therapy,transpupillary thermotherapy,submacular surgery & anti-vegf. Aims & Objectives: The aim of our study was to evaluate the efficacy and safety of intravitreally administered Bevacizumab a humanized monoclonal anti –VEGF in Neovascular Age related Macular Degeneration. Methodology: This non randomized, prospective study was carried out on 75 eyes of 75 patients attending the OPD at M & J Institute Of Ophthalmology and diagnosed as having Neovascular ARMD confirmed on FFA and SD-OCT . After taking written informed consent all patients were injected with intravitreal Bevacizumab 1.25 mg/0.05 ml. Follow up visits were scheduled one week, one month postprocedure and every monthly thereafter. Results: 75 eyes of 75 patients were included in this non randomized prospective study. & 29.33...

Purpose To evaluate the efficacy and safety of intravitreal bevacizumab therapy for neovascular age-related macular degeneration (ARMD). Methods Patients with diagnosis of neovascular ARMD without any other ocular pathology were injected with 2.5 mg of intravitreal bevacizumab. A complete ophthalmic examination was undertaken in all patients, including best corrected visual acuity (BCVA), slit lamp biomicroscopy and ocular fundus examination. Ophthalmic follow-up evaluations included visual acuity measurements, optical coherence tomography (OCT) imaging, and fluorescein angiography at first, second and fourth week post injection. Results 39 eyes of 39 patients were injected. The median age was 76 years-old (range 65–90), median visual acuity was 1.18 logMAR (range 0.18–3.00) and median retinal thickness was 388 microns (range 157–1237). By the fourth week of treatment, the median visual acuity was 0.88 (range 0.18–2.78) and median retinal thickness was 247 microns (range 108–1262). Statistically significant differences were found in visual acuity and retinal thickness before and after intravitreal injection (p=0.002, p Conclusions Our results suggest that intravitreal bevacizumab is well tolerated and is associated with improvement in BCVA and decreased mean retinal thickness by OCT. Further controlled and long term evaluation of intravitreal bevacizumab for the treatment of neovascular ARMD is warranted.

Purpose. To evaluate the change in vision after 3 monthly consecutive intravitreal injections of 1.25 mg of bevacizumab for neovascular age-related macular degeneration (AMD). Methods. A retrospective analysis of 35 eyes was performed. Visual acuity (VA) at initial visit and at each follow-up visit was compared. The injection of bevacizumab was performed at 30-day intervals and patients were observed for 5 months after the last injection. Results. Of the 35 eyes, 9 had received previous treatment with photodynamic therapy with or without 4 mg of intravitreal triamcinolone. VA was measured in Snellen table and transformed into logMAR for statistical purposes. Mean age was 76.66 years (range, 49–90 years). There were 24 (69%) women and 11 (31%) men. Mean VA at the initial visit was 0.92±0.50. At month 1, mean VA was 0.84±0.51 and at month 2 was 0.74±0.51. At month 3, mean VA remained 0.74±0.49. Six and 8 months after the initial visit, VA was 0.79±0.49 and 0.77±0.50, respectively. The...

The aim of this study is to report short-term effect of the treatment of "wet" ARMD (age-related macular degeneration) with intravitreal bevacizumab (Avastin). Prospective study included 36 patients (36 eyes) with "wet' form of ARMD. All patients were over 60 year old (22 female, 14 male). Changes of macula included minimally classic CNV (choroidal neovascularisation) (24), occult subfoveal CNV (10) and first stage of cicatrial CNV (2). Bevacizumab 1.25 mg was administered intravitreally through pars plana using a 27-gauge needle. Patients had no previous eye treatment. Ophthalmic exam before and after the treatment included: Snellen VA (visual acuity) and examination including measurement of IOP (intraocular pressure), FA (fluorescein angiography) and interview with patients. After 4-6 weeks 28 (78%) patients had significant improvement of VA. Median VA improved from 0.083 to 0.200 (p<0.01). Eight patients (22%) had no significant improvement in VA but three of them reported to see more light. FA showed complete resolution of macular edema in 6 patients (17%), partially resolved in 23 patients (64%) and no change in 7 patients (19%). No systemic side-effect was found. Short-term results suggest that intravitreally administered bevacizumab is well tolerated treatment for ARMD with very high number of patients showing improvement in VA.

Purpose. To evaluate functional and anatomic effects of intravitreal bevacizumab in patients with neovascular AMD and initial low visual acuity. Methods. Retrospective case series of 38 eyes with neovascular AMD and initial visual acuity of 20/200 or less, treated with intravitreal bevacizumab injection. Results. Mean followup was 14.1 months ± 7.1 (range: 5 to 24 months). Mean logMAR vision at baseline was 1.38 logMAR ± 0.33, at 6 months was 1.14 logMAR ± 0.37 (P = 0.001) and at 12 months was 1.22 logMar ± 0.33 (P = 0.004). Mean baseline central retinal thickness was 431 µm ± 159.7 at 6 months was 293.43 µm ± 122.79 (P = 10 −4) and at 12 months was 293.1 µm ± 130 (P = 0.004). Visual acuity improved in both patients with or without prior PDT treatment. Conclusions. Intravitreal bevacizumab injection may increase the chance of visual acuity gain in neovascular AMD even in cases with initial low visual acuity.

To evaluate the safety of three dose regimens of intravitreal bevacizumab (Avastin; Genentech, Inc., South San Francisco, CA) for the management of choroidal neovascularization (CNV) associated with age-related macular degeneration (AMD). METHODS. This was a prospective, nonrandomized open-label study of 45 patients with AMD and subfoveal CNV. A standardized ophthalmic evaluation was performed at baseline and at weeks 1, 6, and 12 (Ϯ1) after a single intravitreous injection (1.0, 1.5, or 2.0 mg) of bevacizumab. Main outcomes measures include clinical evidence of toxicity and complications. Changes in best corrected visual acuity (BCVA) and lesion characteristics-macular morphology were also evaluated. RESULTS. The most common adverse events were conjunctival hyperemia and subconjunctival hemorrhage at the injection site. Mean BCVA improved from baseline throughout the study (P Ͻ 0.001; ANOVA with Geisser-Greenhouse correction). Compared with baseline, BCVA was improved at week 1 (P ϭ 0.001), week 6 (P Ͻ 0.001), and week 12 (P ϭ 0.001; Dunnett test). At week 12, the lesion area and CNV area were stable or decreased in 79. 1% (34/43) and in 74.4% (32/43) of patients, respectively, with no deterioration of macular architecture observed in 83.7% (36/43). A dose-related change in BCVA (in Early Treatment Diabetic Retinopathy Study [ETDRS] lines) was observed at week 12 (1.0 mg [ϩ0.3 line]; 1.5 mg [ϩ0.6 line]; and 2.0 mg [ϩ1.0 line]; P ϭ 0.02; nonparametric test for ordered groups).
