Small-Gauge Endoscopy-Guided Pneumatic Anterior Hyaloid Detachment: A New Surgical Technique for Combined Pars Plana Vitrectomy and Pars Plana Glaucoma Drainage Implant.

Abstract

Pars plana glaucoma drainage implant (GDI) occlusion is mainly related to entrapment of residual anterior vitreous gel in the implant. The aim of the present report is to describe a new surgical technique to induce pneumatic anterior hyaloid detachment in eyes with GDI. This is a description of the surgical technique used to induce pneumatic anterior hyaloid detachment. The technique was used in two cases. The first patient had secondary Ahmed valve (New World Medical, Rancho Cucamonga, CA) obstruction secondary to anterior vitreous entrapment; the second patient had neovascular glaucoma secondary to proliferative diabetic retinopathy and underwent pars plana GDI implantation. Endoscopy-assisted anterior hyaloid detachment allows for complete removal of anterior hyaloid and decreases the risk of secondary implant obstruction.
