Baerveldt Glaucoma Implant (Shunt)
The Baerveldt implant is a tube that is placed into the anterior chamber (fluid filled space between the iris and cornea) of the eye that shunts the aqueous humor from the eye. The fluid is drained into a reservoir located back away from the cornea under the conjunctiva (the outer coating covering over the sclera or white part of the eye).
Indications for Use of the Baerveldt Glaucoma Implant (Shunt)
In years past, the glaucoma shunt devices were used in people who had failed with the more traditional glaucoma surgery called trabeculectomy. They were used in certain eye diseases or ocular tissue statuses such as previous eye surgery that has scarred the conjunctiva, neovascular glaucoma, and glaucoma secondary to uveitis did not have good outcomes with trabeculectomy. The Baerveldt implant is now gaining more acceptance as a primary surgical treatment for people with glaucoma that are not controlled with ocular glaucoma medications and laser treatment for glaucoma (selective laser trabeculoplasty).
Success Rate for the Baerveldt Glaucoma Implant (Shunt)
The typical success rate for lowering the intraocular pressure 1 year after the eye surgery is in the range of 14 to 18 mHg with an average final eye pressure in the range of 11mHg and 14 mHg. The success rate is approximately 70% 1 year after surgery.
Complications Associated with the Baerveldt Glaucoma Shunt
Shallow anterior chamber
Tube corneal touch
Cystoid macular edema
The Baerveldt glaucoma implant (shunt) has a successful record of treating glaucoma that has not been well controlled with glaucoma ocular medications and laser treatment (selective laser trabeculoplasty). The shunt is being used more commonly as the primary surgical treatment for glaucoma.
