Surgical treatment of angle-closure glaucoma.

The main objective of surgical treatment in angle closure is to quickly decrease the intraocular pressure and therefore reduce the risk of further glaucomatous optic nerve damage. Surgical treatment of angle-closure glaucoma also helps to ensure that progressive angle closure does not occur, and that the risk of acute angle closure is abolished. The surgical options are diverse and include laser surgery, filtering surgery, lens extraction, combined lens extraction and filtering surgery, angle widening procedures such as goniosynechialysis, lens extraction combined with goniosynechialysis or a combination of procedures.
