Macular Degeneration <\/h1>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Macular Degeneration <\/span>is one of the top three blindness-causing eye diseases in the world. It is estimated that there are more than 190 million people with macular degeneration worldwide, and one in ten of them will lose their eyesight permanently as a result. With an ageing population, the number of people with the disease is expected to exceed 280 million by 2040.1<\/sup>.\n\n

\nMacular degeneration is usually seen in people over the age of 50. However, with the popularity of electronic products and excessive eye use in recent years, there is a trend towards a younger age group. It is common for people's eyes to deteriorate and age prematurely. Macular degeneration is an eye disease that happens with there is damage to the macula.\n\n

\n\nSymptoms of macular damage include decreased visual acuity, distortions in the appearance of lines, etc. The disease is usually caused by the ageing and deterioration of eye function. Delayed detection and treatment can lead to blindness.<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The macula is the central portion of the retina where 90% of photoreceptors are concentrated. It is responsible for focusing central vision in the eye, and it controls our ability to read, drive a car, write, recognize faces or colours, and see objects in fine detail. So it is important to keep your macula healthy in order to see clearly. Macular degeneration is an eye disease that happens when there is damage to the macula. Symptoms of macular damage are decreased visual acuity, distortions in the appearance of lines and darkening of the central vision. The disease is usually caused by the ageing and deterioration of eye function.<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Symptoms of macular degeneration include: central visual field changes: patients will find round, oval, oval, irregular dark spots, black circles, etc. in the center of the visual field; visual impairment: rapid or gradual loss of vision, with acute vision mostly in one eye. Significant decrease; abnormal color vision: abnormal perception of colors, and contrast color sensitivity may also be reduced.<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
