The leading cause of blindness in the elderly?

Eyes are one of the most important senses in the human body, helping us understand the world and communicate with people. However, with the popularity of smartphones and the popularity of modern people with three highlights, it is possible to face a serious eye disease “macular degeneration” in old age. Dr. Huang Rouzhen, Department of Ophthalmology, Taipei Medical University Hospital, said the macula is located in the center of the retina. Although it is only 0.5 cm, it is responsible for about 50% of visual function. Once macular degeneration occurs, it will feel that central vision is damaged. Also includes diabetes, retinal vein occlusion (eye attack), high myopia, and irregular sleep patterns.

Dr. Huang Rouzhen explained that age-related macular degeneration can be divided into dry and wet. Dryness refers to the nodules under the macula and the atrophic lesions that follow, which are mainly caused by aging resulting in abnormal retinal metabolism and malnutrition. The disease progresses more slowly than wet forms, which represent about 90% of all age-related macular degenerations. The wet type are the new blood vessels caused by the abnormal proliferation of choroidal blood vessels that are located under the macula. Because the new blood vessels are prone to rupture and cause bleeding or secretion of components in the blood, the macula is swollen, which will greatly affect vision, good for all elderly people. 10% of macular degeneration. In particular, if there is any vision distortion, loss of vision, blurred vision, or even abnormal color vision, seek immediate medical attention to prevent rapid vision loss.

Dr. Huang Rouzhen said the current treatment for macular degeneration is mainly to reduce the chances of severe visual impairment and to extend the available vision time as much as possible. Because the scars caused by macular degeneration are difficult to remove, reducing the ongoing damage is the first and most important way to extend vision. Target. As medical treatment advances, so do the ways in which patients with macular degeneration are treated.

In the past, the treatment methods for macular degeneration have included laser photocoagulation therapy, transpupillary photothermal therapy, and photodynamic therapy. While they can inhibit angiogenesis, they are more likely to damage normal visual cells; The current main method of treatment is intraocular injection of anti-angiogenesis. Drugs can occlude and narrow abnormally proliferating blood vessels to achieve the goal of improving vision. But whatever type of treatment is used, the focus is on early and continuous treatment. The earlier the treatment, the greater the chance of vision recovery. In addition, Dr. Huang Rouzhen reminded that after treatment, do not forget to check regularly, actively control the original disease (three highlights) and quit smoking, which are the keys to correctness.

Since the macula is the place with the highest content of lutein and zeaxanthin in the human body, it is recommended to consume more dark vegetables and take nutritional supplements to supplement vitamin C and vitamin E to help fight the damage caused by oxidation. Finally, Dr. Huang Rouzhen called on the public to use the Amsler checker to self-monitor, detect symptoms as soon as possible and seek medical attention as soon as possible to reduce the risk of blindness from macular degeneration.
