Effect of vitrectomy and pan retinal photocoagulation concomitant with Ahmed implantation in management of neovascular glaucoma

Abstract:

AIM: To evaluate the efficacy of vitrectomy and pan-retinal photocoagulation followed with Ahmed implantation in management of neovascular glaucoma(NVG)retrospectively.

METHODS: Vitrectomy combined with pan retinal photocoagulation and Ahmed implantation was performed on 15 cases(15 eyes)with NVG. All patients were followed up for 12～36mo. The change of intraocular pressure(IOP), visual acuity, neovascularization of iris, complications were observed.

RESULTS: The visual acuity of 10 eyes was improved postoperative. IOP of postoperative 1, 6 and 12mo were decreased significantly compared with preoperative(P<0.01). Neovascularization of iris was reduced dramatically. No serious complications occurred.

CONCLUSION: Vitrectomy combined with pan retinal photocoagulation followed Ahmed implantation can manage NVG effectively.
