What's wrong with seeing things deform, floating black shadows, and eyes?
2023-10-30
The black shadows that interfere with people's vision can be roughly divided into several categories. Some black shadows are fixed and very black, such as visual field defects. This should be noted, as there may be problems with the fundus retina, such as local retinal detachment. Sometimes, a dark shadow appears in the central field of vision, making it difficult to see clearly. This situation should also be noted, as it may be due to macular degeneration. There is also a type of black shadow that is not particularly large, usually resembling small mosquitoes or flies. Some people may also see black shadows resembling circular shapes that move and float, with their eyes moving and turning left and right. At this point, it is often a problem with the vitreous body. The vitreous body is some gelatinous substance in the center of the eye. When we are young, it is a semi solid part that gradually liquefies and flows like water as we age. During this process, there will be some turbidity, like some turbid spots in a basin of water. So when your eyes move, they also float with you. But in fact, there is no problem with your fundus, so generally there is no need to worry too much. It should be noted that when some people experience moving shadows, there is a small probability that there will also be some holes or degenerative areas in the retina. When these symptoms occur, it is still recommended that you go to the hospital for mydriasis examination to avoid more serious situations. What is it about seeing things deform a bit due to the condition of the macula? Most patients experience visual distortion, which is likely due to problems with the macula. For example, macular membrane, macular hole, macular degeneration, especially age-related macular degeneration in the elderly. The macula can be understood as the central position of the fundus. If there is a problem with this area, the focus will become blurred during focusing, and the patient will not be able to see clearly. The macula is also responsible for people seeing if things are deformed. In addition, macular function is closely related to color. Macular degeneration is a type of disease that accounts for the largest proportion of macular lesions. It refers to the aging of the macula with age or the blurred vision caused by aging, also known as age-related macular degeneration. The age of onset is defined as 50 years old, and patients under 50 years old have a low probability of developing this disease. Age related macular degeneration is divided into two categories: dry and wet. During the dry stage, patients will not experience significant visual impairment, and there may be some blurring or even deformation of their visual acuity. However, overall daily life will not be particularly affected. However, if it continues to progress, approximately 20% to 30% of patients will enter the next stage - wet age-related macular degeneration, which is prone to edema, bleeding, exudate, and can lead to visual deformation, blurred vision, and more severe visual impairment. It is difficult to completely reverse macular degeneration when the eyes are "old" and should rest more. Age related macular degeneration is not only related to age, but also to smoking, drinking alcohol, hypertension, and hyperlipidemia. For elderly people, it is recommended to use their eyes as little as possible. Suggest everyone to use their phones appropriately, spend more time outdoors, walk far away, relax, look far away, and exercise more. In addition, middle-aged and elderly people should also pay attention to a light diet. Eating some colored foods, such as red
