Evolution of benign concentric annular macular dystrophy.

In 1974, Deutman described a family with an autosomal dominantly inherited macular dystrophy that he termed "benign concentric annular macular (bull's-eye) dystrophy." Ten years later, we performed a follow-up examination. Some patients complained of deterioration of visual acuity, night vision, and color vision. The macular dystrophy had progressed. The fundus periphery was more involved and in two patients there were bone corpuscle-like pigmentations. Electrophysiologic examination showed increased photoreceptor dysfunction with equal involvement of the rod and cone system. The patients had an acquired type III blue-yellow color vision defect with pseudoprotanomaly.
