Surgically implantable device for glaucoma relief

摘要

The invention contemplates a surgically implantable device for controlled drainage flow of aqueous fluid from the anterior chamber of the eye into nearby subconjunctival space, all in relief of a glaucomatous condition of excessive pressure within the eye. The device includes provision for so controlling the rate of aqueous flow as to assure against anterior-chamber collapse, thus avoiding irreparable damage which might otherwise result to the corneal endothelium, to the iris, or to the lens of the eye.
