Choroidal neovascularization (CNV) may lead to significant visual morbidity when left untreated. There are multiple known causes of CNV. Broadly, the categories include degenerative conditions (age-related macular degeneration, pathologic myopia, angioid streaks), hereditary degenerative conditions (vitelliform macular dystrophy), inflammatory conditions (ocular histoplamosis syndrome, multifocal choroiditis), infectious etiologies (toxoplasmosis), tumors, traumatic and idiopathic. Elucidating the underlying etiology of a CNV membrane (CNVM) is important for determining the treatment and prognosis of the eye. Tuberculosis (TB) is overall an uncommon etiology for CNV, which is driven by vascular endothelial growth factor (VEGF). In this case series, we highlight four patients who developed CNV with tuberculous chorioretinitis and describe their subsequent management.
