AIM:To investigate the effect of glaucoma drainage implantation in the treatment of open angle glaucoma.

METHODS: Patients with open angle glaucoma treated in our hospital selected as objects from Mar. 2014 to Jun. 2015. They were divided into two groups according to the treatment: the drainage group and the trabeculectomy group. The general operation condition of two groups were observed. Visual acuity, intraocular pressure and complication rate of the two groups before and after treatment were compared.

RESULTS: The operation time of trabeculectomy group was 35.12±3.56min. It was shorter than drainage group(P<0.05). The intraocular pressure and visual acuity of the two groups had no significant difference before surgery. After surgery, the intraocular pressure and drainage of the two groups were reduced. And the implantation group reduced significantly(P<0.05). The level of visual acuity of the two groups before and after surgery had no significant difference. The postoperative corneal abrasions, lens damage and other complications was no significant difference(P>0.05).

CONCLUSION: Glaucoma drainage device implantation for open angle glaucoma have a better therapeutic effect. The operation time is short, the complication rate is low and the clinical value is better.
