title: [Glaucoma surgery and retinal pathology].
abstract: The occurrence of hypertonia during a surgically treated retinal disease is frequent because these disorders often involve the same population of patients. The main cause of postoperative hypertonia remains a preoperative unknown glaucoma. Hypertonia occurring before the treatment of a retinal detachment can result from angle recession glaucoma, ghost cell glaucoma, or Schwartz-Matzuo syndrome; all of which are frequently associated with trauma. Hypertonia occurring after the surgery of a retinal detachment can be caused by scleral buckling, a topical postoperative steroid treatment, or an internal tamponade with gas or silicone. The latter is responsible for severe hypertonia that is frequently resistant to treatment. Hypertonia occurring after the use of triamcinolone is usually controlled with medical treatment. Prior filtrating surgery can lead to technical problems during retinal surgery. The knowledge of pre-existing glaucoma may be reason for cautious management of retinal surgery.
