Macular Degeneration

Macular degeneration is the leading cause of blindness in America. It results from changes to the macula, a pinpoint sized portion of the retina that is responsible for clear, sharp vision and is located directly in the back of the eye.

As macular degeneration advances, a distorted, dark, or empty area often appears in the center of vision.

There are two forms of Macular Degeneration, dry and wet. The dry form is more prevalent, is usually milder and slow to progress. The retina slowly deteriorates and there is no known treatment. There is some recent evidence that certain combinations of vitamins may help to slow the progression of Macular Degeneration. Ask Dr. Ni about this at your next eye exam.

The wet form is so named due to the bleeding that can occur underneath the retina. Sometimes prior to bleeding, the retina will become rippled which will distort vision in a wavy pattern. For this reason, all patients with Macular Degeneration are given an Amsler Grid. The grid is a way to monitor each eye at home on a daily basis to watch for subtle changes in your vision that may indicate changes in your condition. Any changes should be reported immediately to Dr. Ni. Sometimes, the wet form of Macular Degeneration responds to laser therapy.

Some common symptoms of Macular Degeneration are a gradual loss of ability to see objects clearly, distorted vision, a gradual loss of color vision and a dark or empty area appearing in the center of vision.

If you experience any of these, contact Dr. Ni immediately for a comprehensive examination.

One central vision is lost to macular degeneration it cannot be restored. However, low vision devices such as telescopic and microscopic lenses can be prescribed to make the most out of remaining vision. Dr. Ni can help you decide if these devices can help or may refer you to a colleague or Center that specializes in Low Vision and Vision Rehabilitation.
