VISUAL FIELD TESTING
Visual field testing
A visual field test measures your central and peripheral vision and assesses the potential presence of blind spots called scotomas, which could indicate eye diseases. A blind spot in the field of vision can be linked to a variety of specific eye diseases, depending on the size and shape of the scotoma. When performing a visual field test, your doctor actually maps the visual fields of each eye individually.
This test is most frequently used to detect any signs of glaucoma damage to the optic nerve. It is also very useful for the detection of central or peripheral retinal disease, eyelid conditions such as
ptosis or drooping, optic nerve disease, and diseases affecting the visual pathways within the brain.
