Most people don’t know there is a problem in the early stages of glaucoma because it is usually painless, and the side vision tends to be affected first. Sometimes the optic nerve can be damaged, even though the pressure in your eye is within the normal range.
You can use eye drops to lower the pressure in your eyes. All drug treatments carry the possibility of side effects and allergic reactions, and there is also the possibility that they cannot bring the pressure problem completely under control.
Laser treatment may be suitable for you, but often the condition comes back. A viscocanalostomy also carries a lower risk of cataract development than laser treatment.
If you don’t have treatment, your optic nerve will become increasingly damaged. If you leave it untreated you are likely to lose vision in your eye. A viscocanalostomy will not improve your vision but may stop it getting worse.
