goniotomy

A surgical procedure aimed at lowering intraocular pressure by making an incision through the trabecular meshwork to ease the outflow of aqueous humour into Schlemm's canal. This procedure is used principally in congenital glaucoma.

Goniotomy and trabeculotomy are preferred as the initial surgical intervention for patients with PCG because of their effectiveness in reducing the IOP and their relatively low rate of serious complications.[sup][4],[5],[11] The advantages of goniotomy are not to disturb the conjunctiva if filtering surgery is subsequently needed, but it requires a clear cornea to afford an adequate intraoperative view of the angle.[sup][12],[13] In the current study, all of the patients had corneal edema, which made goniotomy difficult to perform.
[sup][16] reported the success rate on 39 eyes with late-recognized PCG undergoing goniotomy between 1 and 2 years was better than that of between 2 and 4 years, and 2–4 years was better than that of older than 4 years.
Goniotomy for glaucoma secondary to chronic childhood uveitis.
Therapeutic goniotomy, a procedure that dissects iris tissue adhesions that are connected to the trabecular meshwork, has shown poor success rates (between 0% and 20%) [13, 18, 20].
Prophylactic goniotomy seems to be efficient for the prevention of glaucoma when early signs of angle changes are found and a success rate between 89% and 100% was recorded.
(2-7) Besides the conventional procedures which include goniotomy, trabeculotomy ab externo and trabeculectomy, many new surgical procedures have been developed as safer and probably more efficacious alternatives.
This can be achieved by incising the meshwork ab interno or ab externo, with goniotomy or trabeculotomy, respectively.
It is thought that goniotomy was first described in 1893 by Carlo de Vincentiis; however it was performed without visualization of the angle and resulted in poor outcomes [9].
Debate 1: Reinvestigating the Basics: Goniotomy versus Trabeculotomy Which Is Better?
The traditional staged approach outlined in most textbooks or review papers on primary congenital glaucoma involves what has been denominated as "angle surgery" (goniotomy in cases with relatively clear corneas) and trabeculotomy (for those with cloudier cornea).
