Role of glaucoma drainage device implantation in the treatment of refractory glaucoma

Refractory glaucoma is one of the main blinding diseases in ophthalmology.Glaucoma drainage device implantation has become one of the main methods of refractory glaucoma.It has been widely used in clinic because of its advantages of safety, effectiveness and less complications.After a large number of clinical applications and innovative development of minimally invasive glaucoma surgery, glaucoma drainage device implantation shows its good treatment prospects.In this paper, the structural features of glaucoma external drainage device (Molteno, Schocket, Baerveldt, Human aqueous drainage, Krupin, Ahmed, Joseph, Whites, Optimed drainage device) and micro-in vasive glaucoma surgery (MIGS) (Ex-PRESS drainage device, Xen Gel Stent, CyPass Micro-Stent, Ab interno trabeculectomy trabectome, Hydrus Schlemm canal scaffold, iStent trabecular micro-bypass stent, SOLX Gold Shunt) were summarized.The drainage device implantations for glaucoma in the role of the refractory glaucoma were reviewed.
