Diagnostic tests help to confirm a diagnosis of glaucoma and to verify that your glaucoma is under control.

These tests are part of a clinical examination in that their findings must be reviewed in conjunction with an eye examination. These tests are divided into ones that test "form", such as the the HRT nerve scan and pachymetry, and those that assess "function", such as visual field testing.

We generally aim to repeat visual field tests every 4-6 months then less frequently once results are stable for several visits in a row. The visual field test becomes a more valuable test once there is an established "defect".

HRT nerve head scans can often find subtle changes in the optic nerve before any change is detected from a visual field test. However, repeating this test more often than every 6 months has not been shown to be beneficial.

We encourage patients to have their visual fields and HRT scans at regular intervals, even if they may not see Dr. Schertzer on that visit. As these tests are prone to fluctuation, Dr. Schertzer is looking for any consistent changes that show up on repeated testing to correlate with clinical findings when he sees you.

Secondly, when the cornea is thin, it is more likely that the other support structures of the eye, such as those surrounding the optic nerve are also thin and more prone to getting damage to the nerve itself or its blood supply.


Services - Diagnostic Testing - Visual Field Testing

Tests of your optic nerve form and function need to be considered along with your clinical exam at the office to help decide whether a change in your treatment is required. A change on just one visual field test often needs to be confirmed by repeat testing and by correlating with the HRT nerve scan and the clinical findings.


Services - Diagnostic Testing - HRT Nerve Head Scanning

The sophisticated software that is part of the HRT scanner, when manipulated by someone who is very comfortable with the program, can be the most sensitive test to determine if someone is beginning to develop glaucoma or, if they already have glaucoma, tell if they are getting worse and might need a change in treatment.


Services we offer - West Coast Glaucoma Center

In addition to seeing patients by referral for glaucoma, we follow patients with established glaucoma and those at high risk of developing glaucoma, often in collaboration with the referring eye care professional. We have the full range of diagnostic testing at our facility, including two visual field machines, an HRT nerve head scanner, two pachymetries, ultrasound, and other imaging devices.


Services - Gloucoma Consultations with Dr. Schertzer

His practice is restricted to patients who either have or have significant risk factors for developing glaucoma such as family history, high myopia, characteristic optic nerve or visual field changes, or raised intraocular pressure. Dr. Robert Schertzer sees new patients by referral only from other ophthalmologists, optometrists, family doctors and other physicians.
