Long-term Outcomes of Domestic Hunan Aqueous-Drainage Implantation in Refractory Glaucoma
摘要
Purpose:To evaluate the long-term outcomes of a non-valved,.Chinese-made Hunan aqueous drainage device(HAD) in patients with refractory glaucoma,.compared to trabeculectomy.Methods:This was a retrospective observational case series,including 27 patients with refractory glaucoma who either underwent HAD implantation (n=11) or trabeculectomy (n=16).The mean follow-up was 27.9±13.5 (mean±SD) months.Intraocular pressure(IOP),visual acuity and postoperative complications were measured.Results:IOP was significantly lower at the last follow-up in both two groups compared with the baseline IOP (HAD:58.4 to 19.0 mmHg,P<0.001;trabeculectomy:58.4 to 23.7 mmHg,P<0.001).One week,1 month and 1 year after the operation,the average IOP of the HAD group was significantly lower than that of trabeculectomy group(P<0.05 at all time points).However,the IOP did not differ significantly between the two groups at the time of last follow-up.Conclusion:HAD implantation serves as a good option to control IOP in refractory glaucoma.
