What is a Goniotomy procedure?
What is a Goniotomy procedure?
Goniotomy is a surgical procedure in which the doctor uses a lens called a goniolens to see the structures of the front part of the eye (anterior chamber). An opening is made in the trabecular meshwork, the group of tiny canals located in the drainage angle, where fluid leaves the eye.
What is the best surgery for glaucoma?
Trabeculectomy, still considered the gold standard in glaucoma surgery (commonly performed today with an antimetabolite such as mitomycin-C), remains the most commonly performed glaucoma surgery, with a high success rate in most groups and glaucoma diagnoses, especially in the hands of an experienced surgeon.
How long does a Goniotomy take?
The goniotomy procedure takes about 20 minutes, but will take longer if performed along with cataract surgery.
How is a trabeculectomy performed?
When performing trabeculectomy, an eye surgeon creates a flap in the sclera — the white part of the eye — underneath the upper eyelid. Underneath this flap, a pathway is created to allow fluid to drain, which lowers eye pressure.
Is it better to have a trabeculotomy or a goniotomy?
Indeed, in a paper published in 1977, the authors state that “In contrast to the results of congenital glaucoma, trabeculotomy is a poor choice of operation for the control of adult-onset glaucoma” [3] It is thought that the torn trabecular leaflets likely scarred down over time potentially worsening the outflow issue beyond pre-trabeculotomy. [4]
What kind of surgery is ab interno trabeculectomy?
Ab interno trabeculectomy and trabeculotomy procedures are a subtype of surgeries that fall under the umbrella of micro-invasive glaucoma surgery (MIGS). The ab interno approach has shown to be effective in a majority of patients when data is analyzed from several different studies looking at individual types of AIT surgeries.
How does goniotomy work for glaucoma patients?
Goniotomy may allow for eye pressure control with or without the use of glaucoma medications. For patients who qualify for the procedure, goniotomy provides an alternative to bleb-forming glaucoma surgeries (trabeculectomy, Xen) or tube shunts. How Does Goniotomy Work?
How is gonioscopy assisted transluminal trabeculotomy ( GATT ) performed?
The surgery is performed in the operating room under anesthesia. The eye is cleaned and numbing medication is applied. An instrument then opens the eyelids. Tiny incisions are made in the front of the eye, and a special lens is placed on the eye to visualize the eye’s natural drain.
