Failure in glaucoma surgery and its management

Surgical management of glaucoma may include many different procedures, but filtering surgery is the most frequent. The subject of operative failure following glaucoma surgery is extremely important to every ophthalmo­logist who does glaucoma surgery. More over, it is most distressing; that what initially appears to he a clinical success eventually proves to be a failure. If we can analyse the patients operated for glaucoma where satisfactory control is not achieved, we can choose a safer and more successful procedure.
