(2009) described a large consanguineous Tunisian family in which central areolar choroidal dystrophy (CACD) segregated as an autosomal dominant trait over 3 generations. There were 21 affected family members, of whom 6 also had drusen. The mean age at onset of visual loss was 47 years, with subsequent gradual deterioration in visual acuity. Examination revealed eye findings representing all stages of disease, from early broadening of the central nonvascular area and parafoveal alteration of retinal pigment epithelium (RPE) with punctiform hyperfluorescent lesions leading to a 'window effect' outlining the lesion, to a well-demarcated loss of RPE and choriocapillaris atrophy with bilateral central relative scotoma in later stages.
