What does a trabeculectomy do?
Trabeculectomy is a type of glaucoma surgery performed on the eye that creates a new pathway for fluid inside the eye to be drained. This is an outpatient procedure performed in the operating room. It is used to prevent worsening of vision loss due to glaucoma by lowering eye pressure.
Why is iridectomy done?
An iridectomy is an iris resection procedure where a portion of its tissue is removed treat an eye condition that affects directly or indirectly the iris, the part of the eye that helps control the size of the pupil to improve the focus of light. It is found immediately after the cornea.
What is Goniotomy?
Goniotomy is an advanced surgical procedure in which your surgeon uses a unique lens (called a goniolens) to view the structures in the front part of the eye.
What is the difference between trabeculoplasty and trabeculectomy?
Regression analysis showed that in both populations laser trabeculoplasty was effective in reducing the intraocular pressure but it was less effective than trabeculectomy in permanently reducing the intraocular pressure to within normal limits.
When is trabeculectomy indicated?
The indications for trabeculectomy are as follows: Primary open-angle glaucoma. Primary angle-closure glaucoma not responsive to iridotomy and/or iridoplasty. Secondary open-angle glaucoma.
What is the difference between iridotomy and Iridoplasty?
Currently, opinion is that laser peripheral iridotomy (LPI) alone is not sufficient to prevent disease progression. Laser peripheral iridoplasty (LPIP) is an alternative and effective way of widening the angle recess in eyes that are affected by primary angle closure (PAC).
What is lamina Cribrosa?
The lamina cribrosa forms the bottom of the optic cup on the inner surface of the optic nerve head. On the outer surface of the optic nerve head, the posterior part of the lamina cribrosa faces the anterior region of the optic nerve.
How long does a trabeculectomy last?
For that reason, a trabeculectomy that works well for five to 15 years may be sufficient to prevent significant vision loss in these patients for the rest of their lives.
What is the meaning of trabeculectomy?
Freebase (0.00 / 0 votes)Rate this definition: Trabeculectomy is a surgical procedure used in the treatment of glaucoma to relieve intraocular pressure by removing part of the eye’s trabecular meshwork and adjacent structures. It is the most common glaucoma surgery performed and allows drainage of aqueous humor from within the eye to underneath…
What is the difference between glaucoma and trabeculectomy?
Glaucoma occurs when the fluid your eye produces, called aqueous humor, is unable to drain normally. This causes the intraocular pressure (IOP) to increase over time, possibly resulting in vision loss or blindness if left untreated. Trabeculectomy lowers the intraocular pressure (IOP) inside your eye.
What can I expect after a trabeculectomy?
“The first two months after trabeculectomy surgery involve frequent visits to see your doctor — sometimes every one or two weeks. Your doctor may need to loosen the flap to drain more fluid from the eye by painlessly removing some temporary stitches from the surgery site using a laser or forceps.”
What is a trabeculectomy for IOP?
Your doctor may recommend a trabeculectomy if your IOP is unresponsive to standard glaucoma treatments like prescription eye drops or medication. Trabeculectomy is used to create a new channel, or “bleb,” through which fluid can drain from the eye.
