Goniotomy

Goniotomy is a surgical operation during which the doctor uses a lens called a goniolens to examine the structures of the front part of the eye (anterior chamber). An opening is formed within the trabecular meshwork, the group of small canals located within the drainage angle, where fluid leaves the eye. The new opening provides a way for fluid to pass through right out of the eye. Goniotomy is a surgery for children only.

What to Expect After Surgery

Babies who have goniotomy for glaucoma need to be watched carefully after surgery to make sure their glaucoma is controlled. The pressure in their eyes must be checked on quite frequently.

Why It Is Done

Goniotomy is used to treat congenital glaucoma if the clear covering (cornea) over the iris (the colored part of the eye) isn’t cloudy.

How Well It Works

Goniotomy is successful for over 80 out of 100 children whose glaucoma wasn’t present at birth. If pressure in the eye increases, repetition of the procedure may be needed.

Risks

Complications of goniotomy include bleeding, infection, and cataracts.
