AIM: To investigate the efficacy and safety of semiconductor 532nm laser peripheral iridoplasty in drug control invalid acute satge of angle-closure glaucoma patients.

METHODS: Patients with 15 uncontrolled eyes of 13 cases treated by semiconductor 532nm laser peripheral iridoplasty were recruited into the study. Preoperative and postoperative visual acuity, intraocular pressure, cornea anterior chamber depth and complications were observed.

RESULTS: Iridoplasty preoperative intraocular pressure(IOP)averaged 60.6±8.8mmHg(1kPa=7.5 mmHg), postoperative 15min decreased to average 37.4±7.3mmHg, postoperative 60min decreased to average 26.2±6.6mmHg, postoperative 3h(17.1±5.3mmHg). The anterior chamber deepened and visual acuity improved. All patients had corneal edema disappeared. There were no obvious complications.

CONCLUSION: Semiconductor 532nm laser iridoplasty for the uncontrolled acute attack stage of angle-closure glaucoma with drug was safe and effective.
