Abstract:
OBJECTIVES. α-blockers are a group of α-adrenoceptor antagonists used by urologists
to treat lower urinary tract symptoms suggestive of benign prostatic hyperplasia. Recent
studies have suggested that these drugs – tamsulosin in particular – are involved in the
development of iris complications during phacoemulsification. The objective of this study is
to investigate the effects of α-blockers – especially tamsulosin – on pupil diameter.
MATERIALS AND METHODS. We measured the photopic, mesopic and post-dilatation pupil diameters
in both eyes of 24 patients (46 eyes in total), 16 of them treated with α-blockers
and 8 of them (16 eyes in total) not treated with any drugs (controls).
RESULTS. All patients treated with tamsulosin showed minor photopic, mesopic and post-dilatation
diameters compared to controls. Patients treated with other α-blockers did not
show any difference compared to controls.
CONCLUSIONS. Even if a small number of eyes was evaluated, our study shows that tamsulosin
- through its selective effect on α1A receptors - is the most involved drug in the Intraoperative
Floppy Iris Syndrome.
