AIM: To evaluate intraocular pressure(IOP)control and visual rehabilitation after placement of the Ex-press^® miniature glaucoma shunt with adjunctive amniotic membrane transplantation(AMT)and mitomycin C(MMC)in patients with post-traumatic open-angle glaucoma during 2y of follow up.

METHODS: This was an interventional, 2-year, observational study. Eighteen eyes were prospectively observed(in 18 patients with traumatic secondary open-angle glaucoma)in which Ex-press miniature glaucoma filtration shunts were implanted with AMT and MMC. The outcome measures included intraocular pressure(IOP), best corrected visual acuity(BCVA), number of antiglaucoma medications, and complications. The progress of all patients was monitored for 24mo.

RESULTS: Complete success(IOP <21 mmHg without glaucoma medications)was seen in 15 of the 17(88.2%)eyes enrolled in the study at 24mo after the operation. IOP decreased from 36.9±4.8 mmHg preoperatively to 15.4±3.5 mmHg at 12mo and 15.5±3.5 mmHg at 24mo postoperatively. Early postoperative hypertension developed in two patients(11.1%)due to postoperative fibrosis. Most of the patients had improved postoperative BCVA values at the final follow-up visit compared to their preoperative measurements. Two patients(11.1%)developed transient hypotony. There were no complications such as hyphema, choroidal effusion, shallow anterior chamber, the device touching the iris, or extrusion of the device.

CONCLUSION: The Ex-press miniature glaucoma filtration shunt with adjunctive AMT and MMC is effective and safe in cases of traumatic open-angle glaucoma. Surgical management is an appropriate surgical treatment in this series of cases.
