Visual Field Testing

A visual field test measures how much 'side' vision you have. It is a straightforward test, painless, and does not involve eye drops. Essentially lights are flashed on, and you have to press a button whenever you see the light. Your head is kept still and you have to place your chin on a chin rest. 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. Your optometrist may ask only for a driving licence visual field test, which takes 5-10 minutes. If you have just asked for a driving test or the clinic doctor advised you have one, you will be informed of the result by the clinic doctor, in writing, in a few weeks. 
 
Normally the test is carried out by a computerised machine, called a Humphrey. Occasionally the manual test has to be used, a Goldman. For each test you have to look at a central point then press a buzzer each time you see the light.  

Dear TSO Patients,

In the interest of protecting the health of our patients and staff, we only see patients with urgent issues per CDC and American Optometric Association recommended guidelines. If you had a routine eye exam scheduled, we will reschedule you for a later date. We are working behind closed doors at this time to see only urgent medical patients. If you have eyeglasses or contact lenses that you need to pick up, please call our office and a staff member will deliver them to your car in the parking lot or we can mail them to you at no-cost. If you have an urgent medical appointment, please call our office to check in and we will come out to get you when it is time. We are implementing these rules to minimize contact to protect you and our staff. We apologize for any inconvenience this may cause. We are available by phone during normal business hours if you need us: 817-241-2914.

Thank you for your support.

Drs. Hassett, Noorali, and Your TSO Staff
