The macula is a medical term for an area in the fundus of the eye, located 0.35 cm below the temporal side of the optic nerve, which is rich in lutein and has a small yellowish concavity called the macula, and is the place where vision is sharpest and invisible to our naked eye. Diseases in the macular area are collectively called “macular degeneration”, which is also commonly known as macular eye, such as: macular fissure, macular anterior membrane, central plasma chorioretinopathy, macular edema, age-related macular degeneration, etc. Macular degeneration does not necessarily lead to blindness, whether it will be blind or not is related to the type of macular degeneration, its severity and whether it is treated timely and effectively. Some macular lesions are serious and have poor prognosis, for example: macular fissure, if not treated in time, the fissure may become bigger and bigger, and eventually lead to blindness, how long the blindness is related to the severity of the disease, once the blindness will be difficult to recover. Some macular lesions have a certain self-limiting condition, for example: central plasma choroidal retinopathy, mostly triggered by mental tension or excessive fatigue, most of them can recover on their own within 3-6 months, but they are prone to recurrence, and multiple recurrences will also lead to irreversible visual impairment. Given that the macula is the most critical part of seeing, it is recommended to seek medical attention as soon as the macula becomes diseased.
