title: Suspected ciliary block associated with Viscoat use.
abstract: Ciliary block or malignant glaucoma is thought to be caused by the misdirection of aqueous into the vitreous. It is refractory to medical treatment and often requires vitreous aspiration. We present a case of ciliary block glaucoma caused by sodium chondroitin sulfate-sodium hyaluronate (Viscoat) gaining access to the vitreous through an unsuspected, small zonular dialysis. Vitrectomy performed through a peripheral iridectomy resolved this severe condition.
