OCTA and Retinal Angiomatous Proliferation

The Role of Quantitative Deep Capillary Plexus in the Pathogenesis of Retinal Angiomatous Proliferation: an Optical Coherence Tomography Angiography Study.

To investigate, using optical coherence tomography angiography, the retinal vascular features in patients affected by RAP.

Retinal vascular anomalous complex represents a distinct form of neovascularization in patients with age-related macular degeneration.

The study investigated the changes in retinal vascular network using optical coherence tomography angiography, a novel and non invasive diagnostic technique that allows to better understand the pathophysiologic mechanism of this neovascularization.

Inclusion Criteria:

• absence of significant lens opacities, low-quality OCT-A images.

Exclusion Criteria:

• age older than 80 years
• absence of diagnosis of retinal angiomatous proliferation and reticular pseudodrusen
• presence of previous ocular surgery, congenital eye disease, high myopia (>6 dioptres), actual or previous diagnosis of glaucoma, optic disc anomaly, macular or vitreoretinal diseases.
• presence of significant lens opacities, low-quality OCT-A images.
