External Choroidal Drainage Using Direct Visualization.

Laura L. Snyder Shriji N. Patel A woman in her 60s with a functional glaucoma tube shunt presented after vitrectomy for epiretinal membrane peeling with symptomatic choroidal effusions not responsive to medical therapy. She underwent a minimally invasive, transconjunctival choroidal drainage procedure, which was directly visualized under a widefield viewing system to prevent intraocular hemorrhage or retinal penetration of the needle. This allowed for preservation of her conjunctiva, restoration of normal intraocular pressure by temporary blockage of her tube shunt with a viscoelastic, and resolution of her choroidal effusions.
