Glaucoma is a sight threatening disease that often goes unnoticed, until it becomes very severe. The worst part of it is, once you lose the vision, you will be unable to recover it even after you start treatment. The best way to monitor for glaucoma is to see your eye doctor on a regular basis. He or she will be able to test you by checking your eye pressure and perform other test to determine the absence or presence of glaucoma. For some people, glaucoma testing may be extensive and may require repeating tests annually. Since glaucoma treatment is indefinite, we as eye care providers want to be certain before starting a patient on drops or recommend surgical intervention.
