Blurred Central Vision

Macular Degeneration or Age Related Macular Degeneration (ARMD)

The macula is a 3 to 5 millimeter oval surrounding the fovea, which is located at the approximate center of the retina (parts of the eye). It has the highest concentration of retinal cones. These sensitive receptors relate colors and are responsible for the perception of fine detail, like face recognition and reading, it is the only portion of the retina that can achieve 20/20 vision. In age related macular degeneration, there is a breakdown in the delivery of nutrients to this region. This results in a thinning of the tissue. In addition, with time, debris deposits begin to appear in this region playing a part in macular degeneration. Each of these contributes to, and both in combination cause, a dimming or distortion to central vision.

Dry Age Related Macular Degeneration (ARMD):

Pigmented spots called drusen, thought to be debris from deteriorating tissue, begin to appear in macular degeneration.
This “dry” form of Age Related Macular Degeneration (ARMD) leads to mild vision problems and may leave the patient more susceptible to the “wet” form of this disease.

Wet Age Related Macular Degeneration (ARMD):

New blood vessels leak fluid killing light sensitive receptors.

The wet form of age related macular degeneration (ARMD) is a severe disorder and warrants immediate attention. New blood vessels growing under the fovea leak fluid. This causes the light sensitive cells near them to wane, resulting in a dramatic loss of central vision. While the peripheral field of view is impacted, the loss of central visual acuity has a tremendous impact on a patient’s motility.
