[Electro-ophthalmological findings in so-called partial "retinopathia pigmentosa" (author's transl)].

A description is given of bilateral, sectoral retinopathia pigmentosa in a female subject and her eldest son. The diagnosis is difficult without an ERG and EOG because of the paucity of symptoms. The disease is characterized by subnormal ERG potentials and a flat EOG curv. In questionable cases, periodic re-examinations and the examination of family members can be helpful.
