Pars plana vitrectomy combined with hyaloido-zonula-iridectomy in treatment of patients with chronic aqueous misdirection: A systematic literature review and case series.

In treatment-resistant malignant glaucoma, vitrectomy combined with a hyaloido-zonula-iridectomy should be considered performed to ensure communication between the anterior chamber and the vitreous cavity. If the condition has been unresolved for a long time, extensive synechiae of the angle may decrease the success rate due to chronic angle closure.
