[A new argon-laser-approach for the management of aphakic pupillary block (author's transl)]

9 cases of aphakic pupillary block with high intraocular pressure were managed successfully by means of a new argon-laser-technique. This new approach consisted in the application at the iris border, 1.5 mm from the pupillary border, of a mobile argon-laser beam of variable intensity, ranging from 250 to 500 mw, of constant time (0.5 sec) and of fixed spot size (200 mu). In some instances the beam was moved parallel and in other cases vertically to the pupillary border in the direction towards the ciliary portion of the iris. This technique ensures maximum retraction of the pupillary border, corresponding to the line of running application, coupled with the least possible damage to the iris and a minimum of applications. Simultaneously with the retraction of the pupillary border the posterior synechiae of the iris are detached and the out-flow of the aqueous trapped in the posterior chamber is released.
