14 Clinical and electrophysiological diagnostic findings for Best's disease. (a) Fundus photo of the left eye of the same 46-year-old Caucasian male patient with Best's disease shown in 12, at the vitelliruptive stage with atrophic foveal changes. Note satellite lesions superior and nasal to the disc as well. (b) EOG of a normal control subject. (c) EOG of the patient shown in (a) with an Arden ratio well <1.5, consistent with diagnosis of Best's disease verified molecularly to be due to an E300K BEST1 mutation
