It's normal for a person to experience vision changes as he grows older. Among the five senses, the sense of sight is usually the first one to be affected by the aging process. However, there's a wealth of difference between vision changes due to age and due to a possible disease. Only an eye doctor like Dr. Paul C Lee can diagnose eye diseases. So, if you think you're experiencing some visual changes, consult with a doctor right away.
Three of the most common eye disorders that affect the elderly are glaucoma, cataract, and macular degeneration, with the latter being the most common cause of blindness in individuals over the age of fifty. The good news is it can often be slowed or even halted if given prompt attention and treatment. Treatment for macular degeneration can include one or more of the following:
Anti-VEGF injection – In wet macular degeneration, the eyes secrete large amounts of vascular endothelial growth factor (VEGF). This substance causes the growth of abnormal blood vessels at the back of the eye. To counter its effects, doctors inject anti-VEGF on a monthly basis to slow the disease process.
Laser photocoagulation – Here, a high-energy beam of light is directed at the affected parts of the retina to destroy the abnormal blood vessels.
Photodynamic therapy – This treatment involves the injection of a drug called verteporfin intravenously so it can travel to all blood vessels of the body, including the eyes. Then, a beam of light is aimed towards the damaged eye area to destroy the said blood vessels.
