Subretinal neovascularization in macular region is a kind of fibrous vascular tissue formed by choroidal neovascularization sprouts crossing Bruch's membrane and proliferating in the subretinal and / or subretinal pigment. It is often accompanied by subretinal serous exudation and / or hemorrhage, which is the main cause of vision loss caused by a variety of fundus diseases. What are the causes of subretinal neovascularization? Next, I'd like to share my views with you.

What are the causes of subretinal neovascularization?

Subretinal neovascularization of the macular region can occur in many retinal diseases. Among them, age-related macular degeneration (SMD), also known as age-related macular degeneration (ARMD), is the most common,

The development and outcome of choroidal neovascularization is the main characteristic of age-related macular degeneration. In addition, high myopia, vascular streak, traumatic choroidal laceration and ocular histoplasmosis were also common.

Choroidal neovascularization (CNV) is a common complication in many kinds of fundus diseases, such as best's disease, acute posterior pole multiple squamous pigment epithelial lesion, chronic uveitis, Harada's disease, chronic choroiditis, toxoplasmosis, sickle cell anemia, Paget's disease, choroidal nevus, choroidal tumor and intense laser photocoagulation.
