THE HEREDITARY macular dystrophies are usually characterized by bilateral, often symmetric, changes of the posterior pole, with specific inheritance and electrophysiologic findings.1 The vitelliruptive macular dystrophy consists of a distinct macular lesion with different appearances in the natural course.2 The electro-oculogram (EOG) shows characteristically decreased light-peak to dark-trough ratios.1 Similar clinical findings with normal EOG were described in adult-onset vitelliform foveomacular dystrophy3 or benign foveal depigmentation.4 In this report, the vitelliruptive macular dystrophy was associated with multiple bilateral, vitelliform cysts and normal electro-oculogram.
