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 license 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 computerized 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.

A Message to Our Patients

Although the Governor has rescinded the mask mandate, we have been advised by the Texas Optometry Association that Optometrists follow Infection Control Guidance for Healthcare Professionals recommended by the Centers of Disease Control (CDC). In addition, most, but not all, of our employees are vaccinated. We are hoping to have our entire staff vaccinated by May 1st, 2021.

Until all staff members are vaccinated, the continued safety and well-being of our patients and staff is our number one focus. Masks will be required to be worn by all patients, visitors, and staff while in our practice. We will also continue to follow the CDC’s guidelines and recommendations throughout the practice.

We thank you for your understanding and helping us protect our patients, families, and staff.
