Glaucoma is a condition which is usually associated with higher than normal pressure in the eye. If it is not treated, glaucoma can result in damage to the optic nerve, which leads to a deterioration in vision. Unfortunately, the damage caused by glaucoma is not often apparent to you in the early stages, which is why your optometrist will check for it at every visit. Glaucoma is treated successfully with eye drops in most cases, but sometimes a glaucoma operation is necessary to control the pressure in the eye. Lifetime monitoring of glaucoma is necessary, to ensure that it is adequately controlled by the treatment prescribed. Initially, I see patients every 2-3 months, but this is extended up to annually once the glaucoma is stable.
