Nonperforating trabecular surgery with reticulated hyaluronic acid implant for treatment of open-angle glaucoma

Objective To evaluate the clinical effect of nonperforating trabecular surgery(NPTS) combined with reticulated hyaluronic acid implant on the treatment of open-angle glaucoma.Methods NPTS combined with reticulated hyaluronic acid implant was performed on 36 eyes of 31 patients with open-angle glaucoma.Postoperative visual acuity,intraocular pressure(IOP),bleb appearance,anterior chamber reactions,anterior chamber depth and complications were observed.The mean follow-up was 12.43±4.12 months.Results The mean preoperative IOP was 32.16±9.41 mmHg.After operation,the mean IOP was 7.56±2.83 mmHg in the first week,15.01±4.65mmHg in the sixth month.The difference was significant(P0.01).After operation,there was no flare in the anterior chamber in 28 eyes.In 2 eyes,there was a small amount of hyphema that was absorbed in 2-3 days and there was shallow anterior chamber that disappeared in 2-3 days.After operation,there was an obvious diffused bleb in each eye and the visual acuity was steady in the first week and in the sixth month.Conclusion The effect of nonperforating trabecular surgery with reticulated hyaluronic acid implant for treating open angle glaucoma is excellent.There are few complications.Therefore,NPTS is a promising and practicable anti-glaucoma surgery for treatment of open angle glaucoma.
