Visual distortion The object seen is not the same as the real one, when looking at a straight line, the good eye sees a straight line, the sick eye sees a distorted line, the horizontal line becomes wavy, etc. The image that was beautiful looks distorted, and the picture that was bright and clear becomes gray and unrecognizable. Macular degeneration The normal macula is a central non-vascular depression in the posterior pole of the retina, with a diameter of about 2mm and a shallow funnel shape, which is rich in lutein. The macula is the thinnest retina with only cone cells, which is in charge of vision and color vision function. When light reaches the macula, it can directly shoot to the cone cells, so the macula is the place with the sharpest central vision, and when the human body dies or the eye is detached from the human body, the area appears to be yellowish, so it is called macula. As the macula is in the optical center of human eye, the target of human eye’s gaze is projected on the macular central concavity, usually the visual acuity measured by the visual acuity meter when we check the visual acuity is the macular visual acuity, once the macular lesion occurs, there will be a significant loss of vision or even blindness, so here we have to emphasize that everyone has macula, what should not be there is macular lesion. Physician’s comment Macular lesion mainly manifests as central vision loss, with central dark spot and distortion of visual objects. The specific manifestation of central vision loss is that when you try to look at a person’s eyes, you can’t see his eyes clearly, but you can see his nose and forehead clearly, when you look at a white wall, there is a dark shadow in the middle of the wall, the visual impairment is not obvious when you look with both eyes, but this feeling is obvious when you look with one eye. What bothers patients most is the inability to read handwriting when reading, and the inability to read text messages and phone numbers on cell phones. The second thing is that the visual object becomes smaller, some patients have macular degeneration, the things seen by the sick eye are smaller than those seen by the good eye. for children under 14 years old, except for trauma, the macular degeneration is mostly hereditary macular degeneration, most of these patients have decreased central vision, the deformation of visual objects is not obvious, most parents mistake it for myopia, only when the vision does not improve when they go to the hospital for examination, they find it is macular degeneration, most of the treatment is not effective. Most of the treatment effect is not good. In addition to trauma and hereditary macular degeneration in young people, the more common is central plasma retinal chorioretinopathy, which is a benign self-limiting disease with good clinical prognosis. The most common macular lesion in elderly patients is age-related macular degeneration. Among them, those without neovascularization and no hemorrhage in the fundus are dry age-related macular degeneration, while those with neovascularization and hemorrhage and exudation in the fundus are wet age-related macular degeneration. People who are suspected of having macular degeneration can go to the ophthalmology department of a large hospital and ask for an Amsler table for self-monitoring, or if you really can’t find it, you can monitor it by looking at the straight line on the letterhead yourself. If you find any vision loss and distortion of vision, you should go to the hospital in time to seek early treatment and maintain adequate living vision.
