Stages Of Macular Degeneration

There are three stages of macular degeneration, which are defined by the size and number of drusen located underneath the retina. Early macular degeneration occurs when medium-sized drusen about the width of human hair are present. This stage does not include vision loss. Intermediate macular degeneration occurs in people with large drusen and pigment changes in the eye, which can only be detected through an eye exam. Gradual vision loss may be present. Late macular degeneration occurs when vision loss from damage to the macula has occurred.

There are two additional stages of late macular degeneration. Geographic atrophy occurs when there is a gradual breakdown of macula cells that are responsible for detecting light. These changes make it hard for the eye to send visual information to the brain. Neovascular macular degeneration occurs when abnormal blood vessels develop underneath the retina and leak fluid such as blood, which may cause swelling and damage to the eye. Having both conditions in one eye is possible.
