title: Pars plana vitrectomy and lamina cribrosa puncture in absolute glaucoma.
abstract: Two patients with refractory end-stage glaucoma who had no light perception underwent pars plana vitrectomy and lamina cribrosa puncture to relieve pain and decrease intraocular pressure. The patients presented with blind, painful eyes and high intraocular pressure (> 40 mm Hg). After the procedure, the pain was relieved and the intraocular pressure was lowered in both cases. The patients remained asymptomatic. Pars plana vitrectomy and lamina cribrosa puncture might be related to the decrease of intraocular pressure, probably by facilitating drainage of aqueous humor through the optic nerve.
