There are three types of retinal detachment: foraminal retinal detachment, detached retina, and exudative retinal detachment. Of these, exudative retinal detachment is relatively quicker to recover and does not require excessive surgical intervention. It is mainly treated for the primary cause, such as exudative retinal detachment, which occurs in some pregnant women during pregnancy. Retinal detachment of foramen ovale is caused by a hole in the retina, and the liquefied vitreous body will pass through the hole into the retinal neuroepithelium, making the detachment occur, so it is related to the scope and size of the detachment. The larger the scope of the detachment, the closer it is to the macula, and the more obvious it affects the visual acuity. If the detachment is in the periphery, even if it is treated early with laser, the patient’s recovery after surgery is very compromised. In the case of detached retinas, which are caused by many other proliferative diseases, the visual impairment caused in the later stages is more serious. Even after surgery, vision recovery is still compromised.
