Non-exudative choroidal and macular neovascularizations: An overview.

ABSTRACT

Non-exudative choroidal and/or macular neovascularizations (NV) represent nowadays a common finding in different retinal disorders. The introduction of non-invasive techniques such as structural optical coherence tomography (OCT) and OCT angiography (OCTA) allowed for easy detection and follow-up of non-exudative NVs. Recognized as a distinct entity, these lesions demonstrate a high variability in terms of pathophysiology, morphology, and prognostic implications. In the absence of a consensus regarding correct classification of subtypes of non-exudative NVs, accurate management through strict follow-up strategies and prompt treatment is required. In this review we offer a comprehensive overview of the non-exudative NV spectrum in various retinal diseases aiming to provide a deeper insight into this clinical entity.
