Chris, elevated interocular pressure, IOP, is a precursor to glaucoma. I would first discuss with your optometrist when you should begin seeing an ophthalmologist as delay in obtaining treatment for glaucoma may lead to irreversible loss of vision.
The optometrist can administer a visual field test which consists of clicking a button whenever you see a flash of light. That will identify any loss.
Treatment begins with eye drops. There's also laser treatments and stents that are often placed during cataract surgery. I've had the lot.
The good news is that glaucoma can be well controlled.
Transport Canada Medical requires annual ophthalmologist reports.
