Mode d'action des opérations antiglaucomateuses, spécialement de la diathermisation du corps ciliaire

The various surgical interventions utilized in glaucoma are by nature trauma. These operative trauma cause a longer or shorter lasting change in the intraocular blood circulation: a new equilibrium between blood and aqueous fluid is established for a long lime or definitely. The result is that the tonus in the interior of the eye is placed at a lower niveau than before operalion. These surgical trauma are specific in the sense that they affect the anterior portion of the uvea, which is the chief seat of production and resorption of the aqueous fluid. The treatment of glaucoma by diathermy conforms to this general rule. The progress aimed at consists in finding the least possible maiming process which, on the one hand, reduces the operative trauma to the strictest minimum, on the other, produces in the highest degree the circulation changes in uvea from which the necessary pressure reducing result depends. From this point of view, those surgical interventions utilizing diathermy deserve notice then they open up the possibility of achieving their aim without opening or incision of the eye, without inroad into the bulbus. © 1942 S.
