Retinopathy is a general term for diseases of the retina. There are many types of retinal diseases, and the severity of different types varies. For example, optic neuritis and central plasma choroidal retinopathy have a relatively good prognosis and low severity if treated correctly and in a timely manner. Fundus lesions such as central retinal artery occlusion, acute retinal necrosis, retinal detachment, and macular tear are relatively tricky to treat and the severity of the disease is higher. Therefore, when retinopathy occurs, it is important to go to a regular ophthalmology institution to determine the specific condition of the retinopathy and provide timely treatment to avoid delay.
