The art of using the perimeter; measurement of the field of vision.
A diagnostic technique that measures a patient's visual field; initially performed manually, but development of automated, computerized techniques has led to high-quality, reproducible results.
A method of mapping the visual field to determine defects in this field.
Also known as the visual field test. A test that produces a map of the complete field of vision, to check whether there is damage to any area of vision.
(puh-RIM-ih-tree): A diagnostic test. Method of charting extent of an eye's field of vision with test objects of various sizes and light intensities. Aids in detection of damage to sensory visual pathways.
A test that measures your side or peripheral vision.
visual field testing of the retina, used primarily for the detection of damaged optic nerve fibers caused by glaucoma
Method of charting extent of visual field as seen by the stationary eye. Aids in the detection of damage to the sensory visual pathways. See Free Eye Tests.
Visual field examination.
A diagnostic exam also known as the visual field test, which measures the degree of damage to your vision. Each eye is tested separately and the length of the test can vary based upon the patient's level of glaucomatous damage.
Perimetry is the systematic measurement of differential light sensitivity in the visual field by the detection of the presence of test targets on a defined background. Visual field testing can be performed clinically with confrontational field testing keeping the subject's gaze fixed while presenting objects at various places in their visual field. This is generally used to explore the extreme boundaries of the visual field.
