Home > Health Library > Trabeculotomy for Childhood Glaucoma
Trabeculotomy is a surgical procedure that lowers the pressure in the eye. The surgeon will locate the drainage angle of the eye and insert a tool to make the opening bigger. This wider opening allows fluid (aqueous humor) to drain out of the eye. Trabeculotomy is a surgery for children only.
If the doctor prescribed eyedrops, use the drops exactly as directed. Your child will probably need to wear an eye patch following surgery. Your child will also need to avoid strenuous activities for as long as the doctor recommends.
Trabeculotomy is a good choice for children who have glaucoma when the clear covering (cornea) over the iris is cloudy.
For children, trabeculotomy or goniotomy are preferred over trabeculectomy, because they are less invasive and less likely to cause cataracts. They also do a better job of lowering eye pressure in children who have glaucoma.
One year after surgery, trabeculotomy was successful for more than 80 out of 100 children who didn't have glaucoma at birth.footnote 1
The most common problem after trabeculotomy is scarring of the new opening in the eye. Scarring prevents fluid from draining out of the eye. Other complications of surgery may include:
