Optic nerve damage treatment in Canada: glaucoma, optic neuritis and the multiple sclerosis question
Two very different problems dominate: glaucoma, which is silent, and optic neuritis, which is sudden. Each calls for a different response.
Glaucoma: silent and common
Pressure inside the eye, thin corneas, family history and age all raise the risk. Side vision narrows first, so people often notice nothing until much has been lost. Regular eye exams, with pressure checks and a look at the nerve, are the best protection for anyone with a relative who has glaucoma.
Treatment aims to lower pressure with drops, laser or surgery.
Optic neuritis and MS
Optic neuritis causes pain with eye movement and a sudden drop in vision, usually in one eye and often in younger adults. Canada has one of the world’s higher rates of multiple sclerosis, and optic neuritis can be its first sign. For that reason an MRI of the brain is often arranged.
Most people recover much of their sight over weeks, but follow-up matters.
Everyday protection
Control blood pressure and blood sugar, avoid tobacco and keep follow-up visits. If drops sting or cause redness, tell your doctor rather than stopping them.

Who should be screened for glaucoma?
People with a family history, diabetes, high myopia or steroid use, and everyone as they age.
Is glaucoma painful?
The common type is painless, which is why it is missed.
How often are checks needed?
Often every three to six months after diagnosis.
