[Possible causes of rise of the intraocular pressure after trabeculectomy and the ways of their correction].

Basing on the results of follow-up of 50 patients repeatedly operated on at the site of previous trabeculectomy, the authors recommend to stick to a certain order of surgical manipulations and stop the intervention when intraocular pressure is reduced to its normal level on the operative table. Such technique, together with the use of a viscous sponge to prevent coarse postoperative adhesions, helped achieve a stable hypotensive effect that was present for at least 2 years in the overwhelming majority of the patients operated on repeatedly.
