The hypotensive effects of ciliary body diathermy without scleral perforation (non-perforating cyclodiathermy)

peer reviewedAll operations performed in respect of chronic glaucoma are effective on account of the permanent widening of the uveal vessels produced thereby, especially those in the region of the ciliary body. A change in the ocular fluid exchange results, characterised above all by increased resorption. In addition, there is later a certain degree of atrophy of the ciliary body, which tends towards pressure reduction owing to a decrease in the formation of aqueous. The operation described, cyclo-diathermy, makes this possible without perforation of the sclera and penetration through the eye wall. It is indicated for both secondary and absolute glaucoma. © 1945 S. Karger AG, Basel

Mode of action of antiglaucoma operations, especially diathermy of the ciliary body

peer reviewedThe 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.

Retrociliary diathermy in therapy of ocular hypertension.

peer reviewedRetrociliary diathermy must be harmless. One must strictly observe certain conditions in order to avoid failure, which would bring a very useful operation into discredit. Technique is very important. The operation is easy and needs no special skill. Nevertheless, experience has shown that results are better when the operation is performed by experienced hands. Correctly executed retrociliary diathermy can often cure ocular hypertension without risk. In certain forms of glaucoma it is the chosen operation. © 1952 S. Karger AG, Basel
