Choroidal neovascularization
Choroidal Neovascularization (pronunciation: kor-OY-dal new-vas-kyoo-luh-ruh-ZAY-shun) is a medical condition that occurs in the eye. It involves the growth of new blood vessels in the choroid layer of the eye, beneath the retina.
Etymology
The term "Choroidal Neovascularization" is derived from three words. "Choroidal" refers to the choroid, a layer of blood vessels and connective tissue between the white of the eye and the retina. "Neo" is a prefix from the Greek word "neos", meaning new. "Vascularization" refers to the formation of blood vessels.
Causes
Choroidal Neovascularization is often caused by Age-related Macular Degeneration (AMD), a medical condition that results in blurred or no vision in the center of the visual field. Other causes can include pathologic myopia, central serous retinopathy, and ocular histoplasmosis syndrome.
Symptoms
Symptoms of Choroidal Neovascularization can include metamorphopsia (distorted vision), scotoma (blind spot in vision), and photopsia (perceived flashes of light).
Treatment
Treatment options for Choroidal Neovascularization include laser photocoagulation, photodynamic therapy, and anti-VEGF therapy. These treatments aim to stop the growth of new blood vessels and prevent further vision loss.
