PURPOSE To evaluate the retinal toxicity of varying doses of bevacizumab when injected intravitreally in rabbits. Bevacizumab has been approved by the US Food and Drug Administration for the treatment of metastatic colorectal cancer. MATERIALS AND METHODS Twelve New Zealand albino rabbits were used for this study and divided into four groups. Four concentrations of bevacizumab were prepared: ...

This retrospective case series reports sustained elevation of intraocular pressure (IOP) after single or repeated intravitreal injections of bevacizumab (Avastin; Genentech, San Francisco, CA) for wet age-related macular degeneration (AMD). All six cases experienced significant and sustained elevation in IOP after single or repeated intravitreal injections of bevacizumab. Initiation or advancem...

PURPOSE To present the long-term effect of intravitreal bevacizumab (Avastin(®)) therapy in a patient suffering from retinal arterial macroaneurysm. METHODS Case report of a 72-year-old female diagnosed with retinal macroaneurysm in the superior temporal artery leading to macular edema. Functional and morphological data at baseline, 4 weeks, 2 months, and 13 months following treatment with tw...

Bevacizumab (Avastin(Ⓡ)) is a monoclonal antibody against the vascular endothelial growth factor (VEGF) receptor that increases the overall survival rate when added to standard chemotherapy regimens in patients with metastatic colorectal cancer. The known toxicities of bevacizumab are hypertension, proteinuria, wound healing complications, arterial thrombosis, bleeding, and gastrointestinal com...

PURPOSE To report on the treatment of exudative age-related macular degeneration by intravitreal bevacizumab (Avastin). METHODS A 78-year-old patient experienced a progressive loss of visual acuity in her right eye due to an occult subfoveal neovascular membrane in age-related macular degeneration. She received an intravitreal injection of 1.5 mg bevacizumab. RESULTS Within 4 weeks after th...

The burden of intravitreal injections has increased tremendously over the past few years. Since traditionally the operation theatre setup is currently used for this procedure, it is increasingly becoming difficult to manage such a patient load in the theatres. To overcome this challenge, office-based setup for intravitreal injection was started. This study was planned to determine the incidence...

Objective: To evaluate the cost-effectiveness of monthly and as-needed dosing protocols using ranibizumab or bevacizumab for the treatment of neovascular age-related macular degeneration (AMD), when the treatment costs of severe ocular and systemic adverse events are considered. Methods: A Markov model was developed to assess the cost effectiveness of each of the following protocols: monthly ra...

BACKGROUND The aim of this study was to evaluate feasibility and toxicity of bevacizumab (Avastin), a monoclonal antibody directed against the vascular endothelial growth factor in children and young adults. PATIENTS AND METHODS Fifteen patients (male: n = 8; female: n = 7; median age, 14.6 years) received bevacizumab for recurrent or progressive solid tumors (carcinoma: n = 3; neuroblastoma:...

INTRODUCTION Safety of Avastin in Lung (MO19390) was an international, open-label, single-arm study, which assessed the safety and efficacy of first-line bevacizumab (Avastin®) in combination with standard chemotherapy in patients (n = 2212) with advanced or recurrent non-small cell lung cancer (NSCLC). A preplanned subgroup analysis was performed to examine these outcomes in elderly patients o...

Intravitreal bevacizumab (Avastin) use in preterm infants with retinopathy of prematurity is associated with severe neurological disabilities, suggesting vascular leakage. We examined the hypothesis that intermittent hypoxia (IH) potentiates intravitreal Avastin leakage. Neonatal rats at birth were exposed to IH from birth (P0)-P14. At P14, the time of eye opening in rats, a single dose of Avas...
