Figure 2. The retinal changes of the affected patients of the family. Retinal dystrophy is one of main clinical features of Bardet–Biedl syndrome (BBS). Fundus pictures (top left: OD; top right: OS) and an angiography picture (bottom right: OS) of IV: 2 of the family showed atypical retinal dystrophy with attenuated vessels, choroidal sclerosis-type change, severe optic disc pallor, and severe macular dystrophy. The fundus changes of the patient are different from the typical retinal dystrophy of retinitis pigmentosa (RP) in BBS.
