Choroidal neovascularization not associated with age-related macular degeneration

Choroidal neovascularization (CNV) is an important clinical finding that is associated with many ocular conditions, including inflammatory, infectious, degenerative, hereditary, and congenital disorders, ocular tumors, trauma, and a few miscellaneous disorders. The growth of new choroidal vessels beneath the retinal pigment epithelium is associated with specific clinical signs. The clinical recognition of CNV plays a key role in the prognosis and management of these disorders. The clinical presentation of each disorder associated with CNV is reviewed in this paper, with comments on the location and the frequency of CNV occurrence.
