Choroidal neovascularization (CNV) is a pathological condition characterized by the formation of new blood vessels originating from the choroid, a vascular layer of the eye. These new vessels break through the Bruch's membrane and invade the subretinal space, which can lead to severe visual impairment. CNV is often associated with several ocular diseases, most notably age-related macular degeneration (AMD), but it can also occur due to other conditions such as myopic degeneration, ocular trauma, and certain inflammatory diseases.
