Glaucoma is a leading cause of blindness in the world. In the most common form, raised Intraocular Pressure (IOP) causes damage to the optic nerve, which eventually leads to irreversible loss of vision. Unfortunately, the patient is not aware of any problem with their vision until very late in the disease process – where most of the damage has been done. That is why we, at the Vision Institute recommend regular eye checks to the over-40’s population, so that the diagnosis can be made at the earliest possible stage. The initial treatment will consist of eye drops to lower the IOP, therefore slowing or halting the progression of the disease. Only a small percentage of patients will require some form of surgery to control the IOP. When surgery is required, special medicines called “antimetabolites” (5-Fluorouracil or Mitomycin C) are sometimes used, to allow better control of the IOP. This may allow the patient to be completely free of drops. Regular checks, usually at 6-monthly intervals with IOP measuring and annual visual field testing are then required.
