[Observations on the treatment of glaucoma with clonidin (author's transl)].

Observations on 50 patients treated for up to 2 1/2 years with clonidin revealed very variable side-effects. A large proportion of these patients remained free from side-effects. In a second, bigger group the side-effects decreased so markedly during the treatment, that this drug could be used again. The effects of this drug on the patients are reported in each case.
