The macula is the central portion of the retina, and 90% of photoreceptors are concentrated in the macula. Macular disease is called macular degeneration. The majority of patients aged over 60, but young people may also have the disease. The main reason of macular degeneration is the leakage of blood vessels under the retina, or damages of photoreceptors due to abnormal blood vessels grow, in which resulting in impaired vision. Symptoms include acuity of central visual, difficulty in color discrimination, or distortions in the appearance of lines, darkening of the center of vision, and even dark shadows shown. If you notice any of the above symptoms, you may contact the ophthalmologist to receive proper treatment as soon as possible.
There are 2 types of Macular Degeneration:“dry”(atrophic) and “wet”(exudative). No pain will cause by both treatment. Patients with dry macular degeneration may experience substantial functional limitations, including fluctuating vision in the early stage. In this case, eye condition must be closely monitored to avoid further deterioration to “wet” macular degeneration. If ophthalmologist diagnosed that there is a high chance of your “dry” macular degeneration turning to“wet” macular degeneration, mixed vitamins will be suggested to reduce 20-30% of chance of exacerbations. However, it must be advised by doctor to avoid excessive absorption. Patients with wet macular degeneration, commonly used treatments include “photodynamic therapy” or “vascular endothelial growth factor inhibition” in the vitreous. The sooner you have found the condition and treat it appropriately, the higher chance you can save and restore your vision. Instead, delayed treatment may cause irreversible damage to vision. Regular eye examination is required to reduce the chance of recurrence.
