[Hydroxychinoline- and zinc-treated acrodermatitis enteropathica and electroretinographic findings (author's transl)].

A meanwhile 13 years old boy had to be treated by hydroxychinolines for a severe acrodermatitis enteropathica since his 1st year of life. At the age of 5 years he showed visual deterioration by atrophia optici. Dose reduction and application of different halogen substitutions were tried. Finally, it was daily oral zinc application and continuous control of the serum zinc level which made disappear all cutaneous and mucous symptoms. At an unchanged ophthalmoscopic status, there occurred a slight raise of vision, an enlargement of peripheric campus and a normalization of the electroretinographic potentials.
