Why an Automated Confrontation Field Test Is a Must for Accurate Diagnosis?

An automated confrontation field test is a way to measure your visual field, or how much you can see to each side while focusing your eyes on a central point (peripheral vision). Conducting a visual field test is called perimetry.

One measure of your visual function is to read letters on a visual acuity chart. This is a measure of your central vision and is the most critical part of your vision. However, that is only one a measure of your visual function. Another aspect is your overall visual field, sometimes referred to as peripheral vision. Although many people mistake it as simply a peripheral vision test, an automated confrontation field tester is actually designed to measure the overall field of vision as it is interpreted by the brain in four neurological quadrants. Different parts of your brain control different parts of your visual field. Results of an automated confrontation field tester can sometimes help physicians made a diagnosis.

Measuring Your Visual Field using Automated Confrontation Field Tester

There are different ways to conduct a visual field examination but testing via automated confrontation field tester is the most effective way to measure the four quadrants of a visual field. This is the most common way used to measure confrontation neurologic visual fields. Both ophthalmologist and optometrists use automated confrontation field tester to perform confrontation visual fields during a comprehensive eye examination. It is performed by having the doctor or technician sits at the center with the patient.

While using automated confrontation field tester, one eye is covered. The other eye focuses directly on the technician’s eye and either one, two or four fingers are held in each of the four quadrants. The patient is not allowed to move their eye or look at the fingers but must respond with how many fingers the technician is holding up. After all four quadrants are tested, the other eye is measured.

When a visual field deficit is discovered with the finger counting method, or if the physicians suspect visual field changes; a more formal method will be used called automated perimetry. An automated confrontation field tester is a computerized instrument that measures the field with different lights of different sizes and brightness. An automated confrontation field tester is able to conduct several different types of field tests in a standardized fashion.

Automated Confrontation Field   

A threshold test measures an individual’s just barely detectable vision and quantifies how sensitive a patient may or may not be of detecting points that are considered normal. These maps of visual sensitivity are very important in diagnosing diseases of the visual system. Different patterns of visual loss are found with diseases of the eye, optic nerve central nervous system.

Abnormal Visual Field Test without Automated Confrontation Field Test Ensures:

ü  Glaucoma

ü  Diabetes

ü  High Blood Pressure

ü  Multiple Sclerosis

ü  Optic Nerve Glioma

ü  Hyperthyroidism

ü  Pituitary Gland Disorders

ü  Central Nervous System Problems, such as a tumor that is compressing one of the visual parts of your brain

Once a visual field defect is detected, doctors will usually repeat the test a couple of times to confirm the results. An automated confrontation field tester gives the result fast. However, the results are somewhat dependent upon the test taker. Once a person has completed at least one test, they usually perform better the second time around. Final assessments are usually not made until after the patient has repeated the test at least twice and sometimes even a third time. Because automated confrontation field testing units also have a computer in them, the reliability of the test can be tracked. Certain statistics are calculated to rule out user error and give the doctor some measure of reliability.
