Factores pronósticos de fracaso de la trabeculectomía en una población de Cuba

Previous trabeculectomy, pre-operative intraocular pressure ≥ 31 mmHg, black race, and advanced glaucoma are prognostic factors for trabeculectomy failure, in decreasing order of their association with surgical failure. The addition of two or more factors increased the risk of failure. In those situations, the use of trans- operative anti-metabolites is suggested.
