[Protein concentrations in the aqueous humor in Coats' disease (author's transl)].

Elevated protein concentrations in the aqueous humor, without Tyndall phenomenon, were found in a case of Coats' Disease. In particular, proteins of smaller size were involved. The permeability of the retinal vessels was presumed to be impaired. The resulting increase in protein concentrations in the aqueous humor could be the cause of the secondary glaucoma in Coats' Disease.
