What is the self-diagnosis method for macular eye disease?

Macular disease is a disease of the human retina. It is usually caused by visual lesions. Some yellow spots will appear on the surface of the retina. The spots are usually not observed, but they can cause eye discomfort. You can self-check by covering your eyes with one hand to determine whether you have macular disease.

Self-diagnosis method for macular eye disease

Cover one eye with one hand and look at distant scenery with the other eye. Check whether the vision of each eye has declined compared to before. For example, look at a window frame with stripes or other utensils with lines or squares to see if the lines become bent, the squares become smaller, or deformed.

In addition, you should also pay attention to whether there are any dark shadows blocking your eyes. Once self-tests reveal abnormal conditions such as progressive vision loss, curved lines, deformed and smaller squares, and dark shadows in front of your eyes, you should go to the hospital for treatment in time.

Causes of macular degeneration

What causes macular degeneration in the eye?

Macular degeneration is a common disease affecting the macula in the elderly. The exact cause is still unknown, and it may be related to genetics, vascular sclerosis, oxidative damage, chronic light damage, inflammation, metabolic nutrition, etc. According to reports, the factors that cause macular degeneration include the following:

1. Age: The older you are, the greater the risk of developing macular degeneration;

2. Gender: Women are slightly more likely to have wet macular degeneration than men;

3. Family history: Some families are susceptible to the disease, although the specific gene for the disease has not yet been found;

4. People with hypertension, diabetes, hypercholesterolemia, cardiovascular disease, obesity, etc. are prone to macular degeneration;

5. Smoking, drinking, and nutritional deficiencies (such as carotene) can also cause macular degeneration;

6. Exposure to blue light and sunlight;

7. 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.

Types of macular degeneration

Macular degeneration is actually very common. Many people around us suffer from macular degeneration, but many friends do not understand its causes. There are usually two types of macular degeneration. One is dry macular degeneration and the other is wet macular degeneration. The following is an introduction to the symptoms of each of them.

Dry macular degeneration: Dry macular degeneration, accounting for 90% of the total incidence, is an aging of the macula that occurs with age. No fundus bleeding or exudation will occur. The disease progresses slowly, vision gradually decreases, and the harm is relatively small. The most common symptoms are: blurred vision, need for more lighting to distinguish details, and difficulty recognizing faces at a distance. As dry macular degeneration progresses, central vision may become blurred, and over time this area may grow larger and darker, leading to loss of central vision.

Wet macular degeneration: Wet macular degeneration, accounting for 10% of the total incidence, is caused by abnormal blood vessel growth under the retina, rupture and bleeding of new blood vessels, and the growth of scar tissue, which causes a sudden decrease in vision and can quickly and seriously affect the patient's central vision, and even lead to loss of central vision. The main symptoms of wet macular degeneration are: rapid weakening of central vision, distorted vision, curved words on paper, and dark shadows or blurred areas in the center of vision.
