Acrylic Gonio-Subconjunctival Plates in Glaucoma Surgery

OF the numerous surgical procedures designed to the dictates of the pleo- morphic demands of glaucoma no one method can be regarded as invariably satisfactory. The very fact that so many operations have been designed for the relief of ocular hypertension suggests that a surgical procedure has yet to be evolved which would adequately restore and maintain normal pressure and save the eye from disaster. The surgeon is consequently forced to select one operation in a given case of simple glaucoma from a long list of possible methods. Sometimes he opens the filtration angle in the hope of establishing an adequate drainage channel, or where this is already obliterated or has been damaged by the pathological process he looks for the seepage of aqueous fluid into the subconjunctival tissue or the suprachoroidal space, through sclerectomies with or without cyclodialysis.
