Glaucoma is a group of eye conditions that affect the health of optic nerve, which is vital for good vision. The nerve damage is often caused due to the high pressure in the eye. The most common reason of this pressure is overproduction of a fluid called aqueous humor. If the drainage system does not work properly, the fluid can't flow out at its normal rate and the eye pressure increases resulting in Glaucoma.
Glaucoma is treated by lowering the eye pressure (intraocular pressure). Depending on the patient’s situation and type of the glaucoma he/she has, there are different options for treatment. One of the options is called Trabeculectomy.
Trabeculectomy is the common non-lasik procedure to lower the pressure in the eye. During trabeculectomy procedure, a small hole is made in the wall of the eye and a flap is created over this hole to allow fluid to escape the eye.
Trabeculectomy is recommended if medical treatments or laser trabeculoplasty have failed to bring the eye pressure low enough. Drainage tubes, such as Ahmed valve, are another option to treat glaucoma.
Please note that, none of the mentioned treatments can cure the damaged caused by glaucoma. Thus, it is recommended to visit an ophthalmologist regularly to be able to recognize this decease on the early stages.
