Measuring Darkness Adaptation to Monitor Macular Degeneration

Many of the common early symptoms associated with age-related macular degeneration are similar to those of aging or cataracts. Colors are not as vivid, vision isn't as sharp, and there is a need for more light.

Loss of Night Vision

However, science has known that one of the early signs associated with macular degeneration has been the loss of night vision or the slow response of adapting from bright light to darkness. But how to evaluate and measure this in patients has not been possible until now.

Gregory Jackson, Ph.D., associate professor of ophthalmology at Penn State Hershey Medical Center and Chief Scientific Officer of MacLogix discusses a test that has been in clinical studies for the early detection of macular degeneration and for monitoring AMD treatments.

This early warning symptom of dark adaptation or loss of night vision shows up long before other tests can show that one has AMD.

That's because the cells that are responsible for night vision are affected sooner and more severely than cells that are responsible for daytime vision.

Monitor Treatment Effectiveness

Changes in the ability to adapt to darkness can be observed and measured before structural changes to the retina can be seen. The testing can also be used to monitor the effectiveness of therapies to treat macular degeneration.

Find out how to get this test and who should be tested by watching this short video:
