Glaucoma is caused by a sustained elevation of intraocular pressure due to the decreased drainage of aqueous humor from the anterior chamber of the eye. There are many types of glaucoma, which, if left untreated, may have devastating results for the patient. Glaucoma can remain uncontrolled after medical and surgical interventions. Glaucoma drainage device implants with pericardial graft placements often are helpful in relieving the effects of glaucoma and increasing the patient's quality of life.
