[The effect of chronic beta-blocker treatment on the evolution of primary open-angle glaucoma].

UNLABELLED

Comparative analysis of the results of the trabeculectomy in primary open-angle glaucoma (POAG) when it was chosen as a primary treatment and when was preceded by chronic use of topic beta-blockers.

MATERIAL AND METHOD

Retrospective study of 59 patients (group A) with primary trabeculectomy and 42 patients (group B) with topic beta-blockers treatment for at least 3 years subsequent to trabeculectomy was performed. The average postoperative follow-up period was 3 years and 5 months.

RESULTS

Postoperative IOP lowering was similar in both groups; There are no statistical differences between group A and B concerning stationary cases (76.27% in group A and 75.4% in group B), regressive cases (6.8% and 7.14% respectively) and progressive cases (18.6% and 17.9% respectively); Preoperative and postoperative complication rates were similar in the 2 groups.

CONCLUSIONS

The chronic beta-blockers use does not influence the evolution of operated POAG.
