[The influence of the fixation of the scleral flap on the hypotensive effect of trabeculectomy].

The author analyzes 60 trabeculectomies with fixation of the superficial scleral flap by three nodular sutures (n = 24) and by one nodular suture (n = 36). He comes to the conclusion that trabeculectomy with scleral flap fixation by one nodular suture is preferable to its fixation with three sutures, for it creates better conditions for the formation of filtration pad and provides a more stable hypotensive effect, as evidenced by the results of three-year follow-up (75% vs. 41.6%). Nonetheless the author claims that fixation of the scleral flap with 3-4 sutures is desirable in cases when filtering trabeculectomy variants are deliberately employed or when trabeculectomy modifications with uveoscleral discharge stimulation are used.
