[Shape of filtration blebs and pressure regulation after trabeculectomy].

The authors describe the results of trabeculectomy in 90 eyes: in 85% the IOP was between 10 and 22 mm Hg with or without additional therapy. About 60% of these eyes had a flat cystic bleb, about 20% were incisible and 20% bullous. The eyes with an IOP of 23 mm Hg or more also had well-formed filtration blebs. No correlation was found between the shape of the filtration blebs and the IOP.
