[The periphery of the iris in glaucoma].

The author surveys, on the basis of some personal observations, the bibliographic data referring to the role of the iris in excretion of the aqueous humor. The second part of the paper reports on the authors clinical material, with emphasis on the great number of cases of atrophy of the iris periphery in the simple glaucoma and that appearing in the advanced age. The book concludes with references on the etiopathogenic correlations between the structural modifications of the iris root and the changes of intraocular tension.
