The prognostic value of the wuerzburg bleb classification score for the outcome of trabeculectomy.

Background: the Wuerzburg bleb classification score (WBCS) aims at an objective and standardized assessment of the developing filtering bleb after trabeculectomy, in order to detect and treat bleb scarring at the earliest possible stage of development. The purpose of this retrospective study was to evaluate the prognostic value of the early postoperative WBCS for the long-term outcome of trabeculectomy.

Methods: the WBCS is a grading system for clinical bleb morphology.
