TESTING FOR GLAUCOMA
At Nicola Eye Care we only use and maintain the most advanced and diagnostically powerful equipment available. During testing your doctor will:
- Assess your ocular health, particularly the inner eye
- Evaluate your visual field
- Confirm the type and severity of glaucoma
One indicator of glaucoma is elevated intraocular (inner eye) pressure (IOP). Tonometry is the process of measuring this pressure – if yours falls outside of normal bounds, it is indicative of a problem. Our state-of-the-art non contact tonometer administers a softer, quieter air puff than older machines, and simultaneously measures, the thickness of your cornea, allowing us to determine the accuracy of our measurements. If needed, we will perform contact tonometry for more precise IOP measurement.
This imaging technique creates an extremely detailed, 3D picture of the retinal nerve fibre layer (RNFL) as it exits the optic nerve head inside the eye. Glaucoma causes thinning of the RNFL that leads to vision loss. This very sensitive test allows us to measure changes to your ocular health before you have lost any vision, and allows us to monitor very closely for progressive changes over time.
Glaucoma destroys side vision, and this exam tells your doctor exactly how limited your visual field has become. We can detect tiny flaws in the peripheral vision, so even if you are in the earliest stages of glaucoma, diagnosis is possible.
