October 22, 2019 updated by: Gilda Cennamo, Federico II University

Study of Retinal and Vascular Features by Optical Coherence Tomography and Optical Coherence Tomography Angiography After Intravitreal Injections of Bevacizumab in Exudative Age-related Macular Degeneration

This study evaluates the retinal and vascular features in patients with macular degeneration under the effects of Bevacizumab intravitreal injections using optical coherence tomography and optical coherence tomography angiography.

Detailed Description

Bevacizumab is a vascular endothelial growth factor antagonist represent an efficacy treatment for exudative age-related macular degeneration acting on vascular hyperpermeability.

The optical coherence tomography and optical coherence tomography angiography represent novel and non-invasive diagnostic techniques that allow a detailed and quantitative analysis of retinal and vascular features.

The study evaluates the changes in optical coherence tomography and optical coherence tomography angiography parameters at baseline and after three monthly injections of Bevacizumab in exudative AMD.
