Glaucoma is a condition in which the eye pressure, also known as intra-ocular pressure (IOP), is too high and thus causes damage to the optic nerve of that eye. Damage to the optic nerve results in progressive loss of peripheral or side vision. Only if suitable medication and Laser treatments have failed to correct the condition, surgery will be considered
Glaucoma surgery is a delicate microsurgical procedure. In this operation, a small piece of the clogged trabecular meshwork is removed to create an opening and a new filtering pathway is made for the fluid to exit the eye. For the new pathway, a small filtering bleb is created from conjunctival tissue. (The conjunctiva is the clear covering over the white of the eye.) The new drainage system allows fluid to leave the eye, enter the bleb, and then pass into the capillary blood circulation (thereby lowering the eye pressure).
