Dry age-related mascular degeneration

Macula is made of light-sensitive cells and the breaking down of these cells leads to dry AMD. This type of age-related macular degeneration appears slowly and leads to the blurring of central vision. Of the two types, dry age-related macular degeneration occurs most commonly and is also known as atrophic AMD as it is caused by the death of the cells in macula.

Symptoms include slightly blurred vision, unable to recognize faces, unable to do simple tasks such as reading in normal light and require more light. An early sign of dry AMD is the yellow deposits, known as drusen, under the retina which can only be recognized by an ophthalmologist during an eye exam. Increase in size and number of drusen worsens dry AMD. Thinning of the macula is another symptom.

In the initial stages, dry age-related macular degeneration will go unrecognized as it can only be found by a detailed examination. Most people realize dry AMD during a later stage, when they need more light to do simple day-to-day activities like reading. A blurred spot in the center of vision is also seen by some people. It is wise to take professional advice during this stage.

In the advanced stage their will be a total breakup in vision with only peripheral vision seen clearly. This is mainly due to the increase in the size and number of drusen. Patients also lose color perception and recognizing faces becomes difficult in this stage. One of the major problems with dry age-related macular degeneration is that it impairs a single eye and since the other eye functions smoothly the problem goes unnoticed. Most people recognize the problem only when both of the eyes are affected.
