Dry age related macular degeneration (Dry AMD) is common in adults over 50. It affects the macula, the center of the retina that supports sharp detail. Macular cells thin over time and central vision drops in one or both eyes. Side vision stays, so it does not cause total blindness.
read more about dry age related macular degeneration ...The cause is not fully understood. Age and genetics drive most risk. Small deposits called drusen build under the macula and stress the retinal pigment epithelium. Over time this process thins macular tissue and reduces central vision. Risk rises with smoking, high blood pressure, high cholesterol, and diets low in leafy greens and fish. Long term sunlight exposure and a family history are linked as well.
Dry AMD damages the macula, which is responsible for central vision and fine detail. As waste deposits called drusen build up under the retina, they disrupt nutrient flow and stress the macular cells. Over time, these cells thin and stop working properly, leading to blurred or dim central vision while side vision stays normal.
Dry AMD symptoms develop slowly, often unnoticed early on, especially if only one eye is affected. Common signs include:
There is no cure. Care focuses on slowing progression and making the most of remaining vision. Doctors often suggest AREDS 2 vitamins for intermediate dry AMD. Stop smoking, eat a diet rich in leafy greens and fish, stay active, and manage blood pressure and cholesterol.
Low vision tools such as magnifiers, high contrast settings, and screen readers support daily tasks. Check vision at home with an Amsler grid. Keep regular dilated eye exams to watch for changes and possible conversion to wet AMD.
Standard contacts do not treat AMD. They can still help by correcting nearsightedness, farsightedness, or astigmatism so you get the clearest view possible. Contacts work well with low vision aids and give an unobstructed field. Your eye doctor will advise if contacts fit your overall needs.
Dry AMD progresses slowly with macular thinning and drusen. Wet AMD involves abnormal leaking vessels and can reduce vision quickly.
Total blindness does not occur. Central vision drops while side vision stays.
UV protection supports general eye health. Use sun protection as part of overall care.
If you have been diagnosed with dry AMD and notice a sudden change in the clarity of your central vision or if straight lines begin to appear wavy, contact a retinal specialist immediately. This could indicate a conversion to wet AMD, which requires urgent treatment to prevent permanent scarring.
