Choroidal neovascularization is a medical condition that's often associated with age-related macular degeneration (AMD). It's a type of abnormal blood vessel growth that occurs in the choroid, the layer of tissue in the eye that sits beneath the retina. This growth can lead to fluid leakage or bleeding in the retina, which can cause vision loss. Though there aren't many synonyms for choroidal neovascularization, they can be used interchangeably, and they include subretinal neovascularization, macular neovascularization, exudative AMD, and wet AMD. Early diagnosis and treatment are crucial in managing choroidal neovascularization and preventing significant vision loss.
