Age-related macular degeneration mainly affects the elderly. The macula is actually the central tissue of the retina that has the best vision and is responsible for central vision, such as reading, driving, or threading needles. So if it starts to degenerate, the patient's best vision will slowly disappear, eventually losing sight of reading.
【Cause】
In the process of converting light into nerve impulses in the retina, some toxins are produced. Normally, these toxins are quickly eliminated. However, as the retina ages, the ability of the eye to automatically eliminate toxins declines, and finally causes macular degeneration.
【Symptoms】
(1) Painless
(2) Blurred vision, most affected in the center of the visual field
(3) Difficulty reading small fonts
(4) Image distortion
(5) Peripheral visual field of the eye not affected
【Treatment】
(1) Laser photocoagulation method
(2) Photodynamic therapy
【Prevention】
(1) Daily self-examination using the "Amsler Grid"
(2) Wearing more sunglasses may reduce the chance of macular degeneration
