How will my optometrist diagnose glaucoma?

As part of your ongoing routine care, your optometrist will regularly monitor your intra-ocular pressure (IOP) and carefully examine your optic nerve.  Should there be concern about glaucoma, further investigation may be recommended, including automated visual field analysis (AVF, or side vision testing), corneal thickness measurement, and optical coherence tomography (OCT, specialized imaging of the optic nerve and retina).  For Ontarians aged 20 to 64, these procedures are not insured by OHIP unless a diagnosis of glaucoma is confirmed, and their cost is the responsibility of the patient or their private insurer.
