If glaucoma is not controlled with the help of medicines, if the side effects of the medicines are not well tolerated and the patient is non-compliant, or cannot afford the cost of the medicines, the second option is LASER TREATMENT, which is given to open up the drainage area for the fluid.
(Glaucoma Filtering Microsurgery or “By-pass” surgery of eye) The operation for glaucoma is the only option left for patients in whom the eye pressure is not controlled with medication or laser. It is also the treatment of choice in non-compliant patients, and in infants and children with glaucoma. Filtering microsurgery involves creating a drainage hole with the use of a small surgical tool, to bypass the blockage in the eye’s trabecular meshwork (the eye’s drainage system). This opening helps increase the flow of fluid out of the eye and thereby reduce the eye pressure.
