Laser Treatment for Glaucoma
Glaucoma laser surgery is performed to lower intraocular pressure by increasing the drainage of aqueous fluid or reducing the amount produced. The type of laser surgery used depends on the type of glaucoma that the patient has. The length of time that the pressure remains lowered depends upon factors including the type of glaucoma, the type of laser surgery, and the patient's symptoms.
Once glaucoma has been diagnosed, treatment should begin as soon as possible to help minimize the risk of permanent vision loss. There is no cure for glaucoma, so treatment focuses on relieving symptoms and preventing further damage from occurring. Most cases of glaucoma can be treated with eye drops, laser or microsurgery. The best treatment for your individual case depends on the type and severity of the disease, and can be discussed with your doctor.
- Eye drops are used to reduce fluid production in the front of the eye or to help drain excess fluid, but can lead to redness, stinging, irritation or blurry vision. Patients should tell their doctor about any allergies they have to minimize the risk of side effects.
- Laser surgery for glaucoma aims to increase the outflow of fluid from the eye or eliminate fluid blockages through laser trabeculoplasty, iridotomy or cyclophotocoagulation.
- Microsurgery involves a surgical procedure called a trabeculectomy, which creates a new channel to drain fluid from the eye and reduce the pressure that causes glaucoma. Surgery is often performed after medication and laser procedures have failed.
