[Clonidine as ointment (author's transl)].

From 15 eyes in 12 patients with chronic simple glaucoma a comparison of the IOP-diminishing effect between 1 drop 0.25% aqueous solution of Clonidine and a 2 cm long application of 0.2% Clonidine-ointment was made with special regard of local and general side effects, especially on the blood pressure. The reduction of the IOP and the blood pressure was greater and of longer duration after ointment application has a definite depôt-effect. Older patients should be fully digitalized beforehand in order to support the cardiovascular system during Clonidine application.
