What is the cause of yellow spots?

Maculoplasm is a kind of obvious color spot that appears in the eye. The cause of macular spot is currently uncertain, so friends who find macular spot should go to the hospital for examination and control the disease in time. The causes of macular degeneration are generally heredity, oxidative damage, inflammation, etc. It is recommended that friends with macular degeneration do not use eye drops on their own, because for different causes, if the wrong eye drops are used, it will be harmful to the eyes.

Causes of macular degeneration:

This disease is a common disease affecting the macula in the elderly. The exact cause is still unknown and may be related to genetics, vascular sclerosis, oxidative damage, chronic light damage, inflammation, metabolic nutrition, etc. It is reported that the factors that cause macular degeneration are as follows: Age: The older you are, the greater the risk of macular degeneration; Gender: Women are slightly more likely to suffer from wet macular degeneration than men; Family history: Some families are susceptible, although the specific gene for the disease has not yet been found; People with hypertension, diabetes, hypercholesterolemia, cardiovascular disease, obesity, etc. are prone to macular degeneration; Smoking, drinking, and nutritional deficiencies (such as carotene) can also cause macular degeneration; Exposure to blue light and sunlight; Environmental factors. Macular disease can be caused by genetic lesions, aging changes, inflammatory lesions, and may also be affected by other fundus lesions. Since a variety of factors can lead to macular degeneration, care should be taken to avoid factors that cause damage to the macular area. Once vision changes or vision becomes distorted, you should go to a professional ophthalmology hospital for diagnosis and treatment in time to identify the cause and treatment to protect your visual function.

Patients with macular degeneration should pay attention to the following in their diet:

1. You can eat more vegetables, fruits and fish products. Because vegetables and fruits contain a lot of antioxidants, such as trace elements, lutein and so on. Some fish contain a large amount of unsaturated acids, which can have strong antioxidant capacity. Both can help prevent macular degeneration.

2. Everyone should also supplement some health care products with antioxidant properties, especially those rich in lutein and zeaxanthin. This will help prevent the progression of macular degeneration.

3. How to prevent macular degeneration? Everyone must actively quit smoking, prevent high blood pressure, eat less greasy food, and exercise appropriately.

The pathological mechanism of macular degeneration is mainly the aging changes in the structure of the macular area. It is manifested by the decreased phagocytic and digestive function of the retinal pigment epithelial cells on the external disc membrane of the photoreceptor, which causes the undigested disc membrane remnant bodies to be retained in the cell protoplasm at the base and excreted outside the cell to form drusen. Therefore, secondary pathological changes lead to macular degeneration. In short, it is mainly related to long-term chronic light damage in the macular area, choroidal vascular sclerosis, and aging of retinal pigment epithelial cells.

Macular discoid degeneration is more common in the elderly, and often affects both eyes or one eye first. It is mostly caused by diseases such as hypertension, nephritis, and diabetes, which cause subretinal or choroidal hemorrhage in the macular area. Clinical manifestations and characteristics: Central vision loss and distorted vision. An absolute dark spot is visible in the center of the visual field. Age-related macular degeneration occurs in the elderly and is limited to the macula. Usually one eye changes first, and eventually both eyes are affected. This disease is caused by sclerosis or blockage of the central choroidal capillaries.
