The most common symptom of macular dystrophy is central vision loss, according to WebMD. Individuals with this rare, genetic eye disorder have difficulty seeing straight ahead, which impairs their ability to perform daily activities, drive or read.
Macular dystrophy damages the cells in the macula, a portion of the retina that is responsible for central vision. The condition develops gradually as a pigment builds up and slowly destroys the cells. Most people experience blurry or distorted vision at first but ultimately retain only peripheral vision, states WebMD.
Macular dystrophy is the result of a genetic mutation and occurs in two forms, an adult-onset form and a childhood form.The childhood form, Best disease, causes varying amounts of vision loss.The adult form usually worsens over time, WebMD explains.
