Other Causes of Choroidal Neovascularization
Idiopathic CNV and Miscellaneous Causes of CNV
CNV may complicate any one of the disorders known to damage Bruch membrane, including inflammatory chorioretinopathies, choroidal neoplasms, traumatic choroidal rupture, optic nerve head abnormalities, and others (Table 4-5). It may also develop in eyes with no apparent risk factors or predisposing lesions (eg, idiopathic CNV). As in other forms of CNV, anti-VEGF therapies have become the treatment of choice.
