title: [When should glaucoma be surgically treated?].
abstract: The medical treatment of primary open angle glaucoma has progressively become more and more efficient and safe, and surgery is therefore mostly restricted to failure of and intolerance to antiglaucoma eyedrops. Glaucoma surgery may thus cause severe complications and a high risk of failure has tempered its prognostic. Nevertheless, when efficacious, glaucoma surgery definitively resolves two major pitfalls of medical treatment: patient compliance and eyedrops tolerance. Moreover, new surgical developments of surgery have come from the new technique of non-penetrating deep sclerectomy, which is actually an external trabeculectomy involving removal of the area of maximal resistance to aqueous outflow. This procedure has a very low risk of complications, much lower than that of standard trabeculectomy, but its efficacy is still controversial. Whatever the technique chosen for filtering surgery, antimetabolites may be used in order to limit the risk of postoperative fibrosis, but they also expose to specific, sometimes sight-threatening, complications. Therefore, the most important--and also the most difficult--choice for treating glaucoma patients still remains the best timing for surgery, either excessive, useless, and aggressive medical treatment, or systematic primary surgery.
