Age-related macular degeneration is one of the most common eye diseases, along with glaucoma and cataracts, but public awareness is relatively low. This disease is more common in people aged 65 to 85, with 75% of patients aged 85 to 65 and about 75% of patients aged XNUMX to XNUMX. Age-related macular degeneration is divided into two types: dry and wet. If wet macular degeneration is not treated in time, vision may deteriorate sharply within two years, so the elderly should be vigilant.
Ophthalmologists point out that many people tend to ignore
Age-related macular degenerationThe severity of this disease. The causes of this disease are complex and are closely related to genetic factors, eating habits, etc. Macular degeneration affects central vision, and vision gradually deteriorates with age. Free radical damage leads to macular retinal degeneration, and the patient's central vision becomes blurred, and even straight lines become curved. The ratio of patients with dry to wet macular degeneration is about nine to one. At present, there is no cure for dry macular degeneration, and regular monitoring and prevention of deterioration are the main methods.
Patients with wet macular degeneration may experience serious conditions such as bleeding, scarring and leakage. The golden time for treating wet macular degeneration is within three months, and drugs need to be injected into the eyeball to inhibit the lesions once a month, and at least three injections are required. If treatment is delayed, vision may decline significantly within two years. Some patients undergo vision tests after their condition worsens. They can only see the fonts above four lines when they can clearly see the lower lines of the test chart (better vision) originally.
When age-related macular degeneration develops to the late stage and forms scabs, drug injections are ineffective, and patients can only rely on auxiliary tools to help them see. Currently, there are limited choices of low-vision glasses on the market. There are some new low-vision glasses abroad. Doctors can adjust the glasses according to the patient's perception and adjust the brightness, contrast, etc. The patient can also enlarge or reduce the image by himself. However, once vision deteriorates, it cannot be restored, so early prevention and protection of the eyes are crucial, and the elderly should have regular eye examinations every year.
It is said that foods such as blueberries, carrots, and deep-sea fish can help protect the eyes. Doctors say that salmon is rich in
Omega-3 fatty acids, fruits and vegetables also contain vitamins, which help prevent vision deterioration. As for the wide variety of nutritional supplements on the market, doctors recommend that if necessary, you can choose specific vitamin products or consult a doctor first. In addition, eating more green leafy vegetables, drinking plenty of water, avoiding high-fat foods and quitting smoking can also help reduce the risk of age-related macular degeneration.
