Glaucoma is a disease of the eye that, if untreated, damages the optic nerve resulting in a loss of vision. The optic nerve, located in the back of the eyeball, sends visual information to the brain for it to create an image. The initial symptoms of glaucoma is loss of peripheral vision, or side vision.
The damage caused by glaucoma to the optic nerve originates by increased intraocular, inside the eye,pressure inside the eyeball. It occurs when excess fluid accumulates in the eye usually secondary to poor drainage. The loss of vision caused by glaucoma is usually irreversible.
Canaloplasty is a treatment for glaucoma that attempts to correct the drainage problem to decrease the intraocular pressure thus saving the remaining vision of the patient. It has been reported that Canaloplasty reduces the intraocular pressure by forty percent. The procedure consists of placing a micro catheter into the eyes internal draining duct called the Schlemm’s canal. This catheter alleviates the increased intraocular pressure by helping drainage through the canal. The drainage can remain in place for years maintaining the canal open for drainage.
The risks of the procedure include bleeding which has been reported in thirty percent of the patients. The bleeding usually stops spontaneously and the blood is reabsorbed. A temporary post surgical increase in intraocular pressure has also been reported in some patients. This increase is the result of swelling in the area caused by the operation and recedes in time. In six percent of the cases a blister may develop in the area of the incision that also resolve spontaneously. As in all surgical procedures infection may present in a small number of cases. These are usually treated with antibiotics with excellent responses. Rarely, low intraocular pressure may be a result of the procedure. Surgical revision, the need to perform additional surgery, may be necessary in some cases.
