Intravitreal injection of tissue plasminogen activator as treatment for an occluded pars plana glaucoma tube
نویسندگان
چکیده
Implanting glaucoma tubes through the pars plana in the setting of a corneal transplant is becoming more common, and there are unique problems associated with such a procedure. A 42-year-old man with multiple previous eye surgeries presented with a nonfunctioning pars plana glaucoma tube. There was no view to the tube tip, but it was presumed to be clogged with fibrin. Intravitreal tissue plasminogen activator (tPA) was injected through the pars plana which resulted in intraocular pressure control without further surgery. This new application of intravitreal tPA has not been reported previously. Future research should investigate the optimal effective and safe dose of intravitreal tPA injection to relieve such occlusions.

C urrently there is no established standard of care for central retinal vein occlusion (CRVO). The conditions that are targeted by current treatments are neovascularization and macular edema. Panretinal photocoagulation (PRP) is accepted as an established treatment for neovascularization, but a consensus has not yet been reached on the indications for and timing of the procedure. Recent large-s...

BACKGROUND AND OBJECTIVE The objective of this study was to compare visual acuity outcomes between the following procedures used to treat submacular hemorrhages: pneumatic displacement followed by intravitreal tissue plasminogen activator (tPA) if needed (pneumatic ± tPA) and pars plana vitrectomy (PPV) with subretinal tPA (PPV + tPA). PATIENTS AND METHODS This is a retrospective chart review...
متن کاملPars plana vitrectomy with pars plana tube implantation in eyes with intractable glaucoma.
AIMS Intractable glaucoma is glaucoma resistant to medical therapy and conventional surgical procedures. In this study, a planned surgical technique is discussed for controlling the increased intraocular pressure in selected cases with intractable glaucoma. METHODS Total pars plana vitrectomy with pars plana tube implantation was performed in 17 eyes of 17 cases with intractable glaucoma. Pat...
