Abstract
Aqueous shunts are considered the first-line intraocular pressure-lowering surgery in the setting of neovascular glaucoma. Although aqueous shunts differ in size, material composition, and the presence or absence of a valve, they share a common design that consists of a silicone tube that shunts aqueous humor to an endplate, creating an overlying equatorial fornix-based capsule. In the setting of neovascular glaucoma, the advantages of an aqueous shunt over trabeculectomy include (1) the presence of a permanent sclerostomy (the tube); (2) aqueous drainage to the equatorial region where the potential for conjunctival scarring may be less than the limbal conjunctiva; (3) a predetermined capsular area (the endplate). This chapter will discuss the mechanisms, surgical techniques, outcomes, and complications of aqueous shunt surgery in the setting of neovascular glaucoma. Implant types described in this section include the Molteno, Krupin, Schocket, Baerveldt, Ahmed glaucoma valve, and the Ahmed ClearPath. Additionally, this chapter discusses outcomes of combined retinal treatment and aqueous shunt surgery and secondary treatment options if aqueous shunt failure occurs.
