Fundus macular degeneration refers to a lesion in the macular area of the eye, and is a collective term for a large group of diseases. The macula is the central part of the retina in the fundus, which is a normal anatomical structure, not a disease. The main symptoms of fundus macular degeneration are central vision loss, central dark spot, visual distortion, that is to say, seeing things in the middle is not visible or dark in the middle, or seeing things with distortion and discoloration. Ophthalmic examination shows edema, exudation, hemorrhage and pigment abnormalities in the macula of the fundus. The best examination method is OCT examination, and if necessary, fundus angiography is needed to make a clear diagnosis. There are very many kinds of fundus macular lesions, the most common ones are central plagioid choroidal retinopathy, age-related macular degeneration, diabetic macular edema, macular edema with retinal vein obstruction, macular anterior membrane, macular fissure, highly myopic macular lesion, etc. In addition, it can also be caused by trauma, drugs, genetics, intraocular inflammation, photodamage and other etiologies. All in all, macular disease is a collective term for lesions involving the macular region of the fundus of the eye. Since the macular region is the most important area to form vision, once the symptoms such as blurred and distorted vision and central visual field defects appear, you should go to the hospital promptly.
