Micro-incisional Glaucoma Surgery for Neovascular Glaucoma

Abstract

AbstractOne of the central goals in the treatment of neovascular glaucoma (NVG) is control of intraocular pressure to prevent glaucomatous optic neuropathy. To date, surgical strategies to achieve this goal rely on either decreased aqueous production via cyclodestruction or increased aqueous outflow via ab externo trabeculectomy or aqueous shunt implantation. Although aqueous shunts are relatively effective, they are associated with risks and complications throughout the patient’s lifetime. We suggest that in a select group of NVG patients, adequate intraocular pressure control may be achieved via ab interno angle-based microinvasive glaucoma surgeries, thereby restoring the physiologic aqueous outflow pathway and avoiding the risks and complications associated with ab externo aqueous shunt implants.KeywordsNeovascular glaucoma (NVG)Microinvasive glaucoma surgery (MIGS)Gonioscopy-assisted transluminal trabeculotomy (GATT)Kahook dual blade (KDB)Aqueous shuntTrabeculectomyIntraocular pressure (IOP)
