During the outpatient clinic, patients often say, “Doctor, the physical examination said I have macula, I am very worried, I heard that macula affects vision very much, so today I would like to ask you to check whether my macula is serious or not.” Hearing such words, we know that patients actually have a very unclear concept of “macula”. What is “macula”? 1.What is “macula”? It is not the name of a disease, but the name of an important part of the retina. So, we all have it – the macula. 2.Where is “macula”? It is in the very center of the retina. The part of the eye where light is projected directly from outside is the macula. 3. What are the characteristics of “macula”? The macula is located in the center of the retina; it has the most number of dense photoreceptor cells; it is the most important location for the formation of central vision; it is the most sensitive area for vision; the macula is not yellow (the area in the center of the retina, which is a bit dark and black in color, is the macula) 4. 5.What is “macular degeneration”? All retinal and choroidal diseases occurring in the macular area are collectively called “macular degeneration”. There are many kinds of macular lesions, common: (1) age-related macular degeneration; (2) macular anterior membrane; (3) macular fissure; (4) central choroidal retinopathy; (5) central exudative retinopathy; (6) macular edema 6, macular degeneration: is a kind of lesion, the highest incidence in the elderly. 7, the symptoms of macular disease features: Significantly reduced visual acuity; visual objects deformation, smaller, curved; central vision loss, where you want to see, where you can not see, the afterglow can still be seen.
