Abstract

BIDAGUREN, A. et al. Floppy-iris syndrome associated with tamsulosin: A prospective case-control study. Arch Soc Esp Oftalmol [online]. 2007, vol.82, n.6, pp.349-354. ISSN 0365-6691.

Objective: The main objectives of this study were: To assess the incidence of the intraoperative floppy-iris syndrome associated with tamsulosin and to analyse the incidence of intraoperative and postoperative complications as compared to a control group. Secondary objectives were: to describe the pupillary modifications associated with tamsulosin and to quantify the endothelial cell loss. Methods: A prospective review of 38 eyes of 38 patients was performed. Patients were assigned to two different groups. Group 1 (cases) included 19 eyes of 19 male patients taking tamsulosin, and group 2 (controls) included 19 eyes of 19 male patients not taking tamsulosin. Results: Only two patients (10%) of our study had the complete triad seen in floppy-iris syndrome; 9 patients (47%) showed 2 of the 3 main features of the syndrome and only 2 patients showed iris billowing during phacoemulsification. None of the patients in group 2 showed any of the characteristic intraoperative features. The complication rate was similar in both groups. Conclusions: Intraoperative floppy-iris syndrome occurred in 67% of the patients treated with tamsulosin. The only postoperative secondary effect was a lower pupil reactivity in patients taking tamsulosin.
