Visual Field Test
The Zeiss Humphrey Field Analyser provides the gold standard visual field test. Combined with our Zeiss Cirrus HD-OCT, this instrument is essential in the diagnosis and management of Glaucoma. Similarly, conditions such as strokes and pituitary tumours in the brain can cause visual field loss. So it is helpful in those situations too.
How does a visual field test work?
Visual fields testing (also known as computerised perimetry examination) provides the Optometrist with specific information on the status of your vision, in particular, the parts of your peripheral or side vision that you may not even be aware of.
The test itself only takes a few minutes and is completely painless. Your test results are combined over time, so each additional test adds to the overall picture. Furthermore, the technology can extrapolate trends over time. So this provides the Optometrist with some certainty in predicting the future health of your eyes.
How will you benefit from a visual field test?
Over 300,000 Australians currently suffer from glaucoma, which has few symptoms and can lead to blindness. Glaucoma progressively and silently destroys the nerve fibres in the back of your eye. Consequently, sufferers will experience permanent loss of sight.
A visual fields test is capable of picking up the initial stages of this condition before significant loss of sight. There is no cure for glaucoma and damage is permanent, therefore early detection and treatment are essential.
This test is also useful in the diagnosis and management of other health conditions associated with the brain including tumors and strokes. Your ability to safely drive a vehicle also depends on your visual field. To renew your driver’s licence, you may be required to complete this test.
Who should have it?
Visual fields tests are recommended for people over the age of 40 or where there is an increased risk of conditions that can cause irreversible vision loss.
