摘要

AIM:To describe the clinical results of combined Ahmed valve implantation and 23-gauge vitrectomy for medically uncontrolled neovascular glaucoma(NVG)secondary to proliferative diabetic retinopathy(PDR).METHODS:The medical records of medically uncontrolled NVG patients with PDR who underwent Ahmed valve implantation and 23-gauge vitrectomy between March 2016 and December 2018 were reviewed.Enrolled patients had at least 6-month follow-up.Panretinal photocoagulation(PRP),anti-vascular endothelial growth factor,surgery and medication history were documented.RESULTS:Eleven eyes of 11 patients were included in our study.The visual acuity improved in 8 eyes and remained unchanged in 3 eyes.The preoperative intraocular pressure(IOP)was significantly decreased at the last follow-up(48.8±4.3 to 17.0±1.5 mm Hg,P<0.001).All eyes needed three topical anti-glaucomatous medications before surgery,but the number was significantly reduced to 0.72±0.19 at the last visit(P<0.001).Four eyes had choroidal detachment and 3 eyes had minor hyphemia,all of which gradually resolved without treatments in one week.CONCLUSION:Ahmed glaucoma valve implantation combined with 23-gauge vitrectomy might be a safe and alternative treatment for NVG with PDR.
