Visual Field Testing

A visual field test measures the range of your peripheral or “side” vision to assess whether you have any blind spots (scotomas), peripheral vision loss or visual field abnormalities. It is a straightforward and painless test that does not involve eye drops but does involve the patient's ability to understand and follow instructions.

An initial visual field screening can be carried out by our North Columbus optometrist by asking you to keep your gaze fixed on a central object, covering one eye and having you describe what you see at the periphery of your field of view. For a more comprehensive assessment, special equipment might be used to test your visual field. In one such test, you place your chin on a chin rest and look ahead. Lights are flashed on, and you have to press a button whenever you see the light. The lights are bright or dim at different stages of the test. Some of the flashes are purely to check you are concentrating. Each eye is tested separately and the entire test takes 15-45 minutes. These machines can create a computerized map out your visual field to identify if and where you have any deficiencies.

VEP Technology Used By Our North Columbus Optometrist

The VEP Vision Testing System helps eye care professionals at Golden Triangle Eye Clinic detect vision deficits, including glaucoma and other neuro-visual disorders.

Glaucoma is the second leading cause of blindness in the world, reports the World Health Organization. According to Prevent Blindness America, glaucoma is often called the “sneak thief of sight” because half of all patients who have it do not know it. Many optic nerve disorders are asymptomatic since central vision may not be affected until later stages of the disease. Also, diagnosis and management of optic nerve disorders are often based on structural or visual field tests which are limited in their ability to detect disease early.

The VEP allows clinicians to objectively assess vision disorders often earlier than traditional vision tests because it uses Visual Evoked Potential (VEP) technology and software to evaluate the entire vision system from the eye to the visual cortex. It records the electrical response of a patient’s entire vision system and provides easy-to-read reports that give the doctor a simple way to evaluate optic nerve function.
