Test, visual field: A test which measures the extent and distribution of the field of vision.

The visual field test may be done by a number of methods including what are termed confrontation, tangent screen exam and automated perimetry.

Although the test may seem tedious, it is not painful or uncomfortable.

Many diseases can adversely affect the visual fields including glaucoma, strokes, high blood pressure (hypertension), diabetes, multiple sclerosis, and overactivity of the thyroid gland (hyperthyroidism). Medications can also affect the visual fields, including antimalaria medicines such as chloroquine/ATABRINE and hydroxychloroquine/PLAQUENIL.
