Practically all the facts and theories concerning cyclodialysis which had accumulated up to 1920 were clearly and thoroughly presented in Salus' paper of that year.1 With regard to the mechanism of the operation, his opinion was stated as follows:

The pressure-relieving effect of the cyclodialysis depends, with great probability, on a partial atrophy of the ciliary body, which is produced by obliteration of numerous arteries and perhaps also by damage done to ciliary nerves. While this atrophy develops gradually after the operation, the eye presents the picture of a mild cyclitis. Because of the lowered function of the secretory apparatus, the intra-ocular pressure is reduced and a more or less pronounced degree of hypotony, depending on extent and degree of the atropic changes, sets in.

Meller, in his textbook on "Ophthalmic Surgery" (first edition), expressed a similar opinion: "The secretory function of the ciliary body seems to
