Visual Field Testing
A visual field assessment is a non-invasive diagnostic instrument used to monitor your central and peripheral vision and provide information on the function of the retina, optic nerve and brain. Visual field assessments are commonly used for conditions such as glaucoma, however it can be used to assess damage caused by tumours, strokes and other conditions affecting your optic nerve.
The Humphrey Matrix instrument uses frequency doubling technology (FDT). This enables the detection of visual field defects in the very early stages. This has particular significance for patients with glaucoma as most people are unaware that they are developing the condition until the disease is well established. Earlier detection of subtle visual fields in early glaucoma with this highly specific assessment method improves the success of treatment in glaucoma to help prevent avoidable vision loss.
