Laser cyclotrabeculospasis in the system of laser treatment in glaucoma.

Different methods of glaucoma treatment by laser have their specific indications and taken together can be considered a kind of "system." A new method of so-called laser cyclotrabeculospasis was developed for use in open-angle simple glaucoma. The anterior surface of the ciliary body (seen gonioscopically) is coagulated by a conventional (argon-gas) laser close to the scleral spur. Tractional pull onto the trabeculum and the inner wall of Schlemm's canal is a probable explanation for hypotensive effect of the procedure and the improved aqueous outflow. There is no risk of serious complications. The laser cyclotrabeculospasis was used clinically to limit the use of surgery, but potentially the method may have some advantages over therapy by drugs as well.
