Definition of Butterfly-Shaped Macular Dystrophy

Reviewed on 9/9/2021

Butterfly-shaped macular dystrophy is an inherited condition that causes accumulation of pigment in the macula of the retina, leading to vision changes similar to those of age-related macular degeneration. In this condition, the deposited pigment takes on the shape of butterfly wings. This condition belongs to a group of conditions known as patterned dystrophies of the retina. The condition is caused by genetic mutations and is inherited in an autosomal dominant pattern. This means that only one copy of the altered gene (from either parent) is needed to cause the condition.
