Pars plana placement of Ahmed glaucoma valve tube through sclerotomy port in refractory glaucoma: A novel surgical technique

Richa Gupta et al. Indian J Ophthalmol. 2020 Jan.

Abstract

We describe a case of 34-year-old male with post penetrating keratoplasty glaucoma, post trabeculectomy with aphakia in the only seeing eye, in which a modified surgical technique of inserting Ahmed glaucoma valve (AGV) tube in vitreous cavity was done to reduce the risks associated with pars plana incision during pars plana vitrectomy (PPV). A hybrid 20-25 gauge PPV was done concurrently, implant fixed to sclera, and tube inserted through the 25 gauge sclerotomy port in supero-temporal quadrant. Visual acuity and intraocular pressure remained stable during 1-year follow-up.

Keywords: Ahmed glaucoma valve; glaucoma drainage device; pars plana vitrectomy; refractory glaucoma.
