METHODS：This is a prospective cohort comparative single-center study. Forty-nine eyes of 49 patients were enrolled in the study. Patients were randomly divided into two groups. Group A（22 patients） underwent classic trabeculectomy and group B（27 patients） underwent modified deep sclerectomy combined with insertion of Ex-PRESS model P50 drainage device. RESULTS：Mean age was 69±7y in group A and 64±8y in group B（P=0.03）. The mean reduction was 11.1±5.7 mm Hg in group A compared to 15.8±5.7 mm Hg in group B at 6mo（P=0.006）, and 9.8±4.9 mm Hg and 15.4±4.7 mm Hg respectively at 1y（P=0.0001）. Regarding the postoperative glaucoma medication, significant difference was observed between the two groups（in favour of group B） only at 6mo（P=0.017）. At the end of the follow-up period complete success rate in group A was 68.2% compared to 92.6% in group B（χ^2 test, P=0.07） and qualified success rate was 100% in both groups.CONCLUSION：Modified deep sclerectomy combined with Ex-PRESS shunt may provide comparable IOP reduction with fewer complications in management of primary open angle glaucoma.展开更多
