Visual Field Testing
The visual field is the entire area that we can see when we focus on a central point, including our peripheral or side vision.
When you come in for a comprehensive eye exam at Hanna Eye Care, Dr. Muneer N. Hanna may recommend a visual field test. This is a quick and painless exam that checks for blind spots or loss of peripheral vision. It determines if you have any vision loss in the side, upper, or lower areas of your visual field.
Why is visual field testing important?
Visual field testing is a crucial aspect of eye care, whether you are at risk for eye diseases or simply want to ensure your visual health. This test is fast and easy, allowing Dr. Hanna to evaluate your peripheral vision and identify any blind spots or concerns. By identifying any problems early on, you and your doctor can work together to develop a plan to prevent further damage to your eyesight and maintain your visual health.
Who should get visual field testing?
Dr. Hanna may recommend visual field testing if you have certain risk factors, such as:
- A family history of glaucoma or other eye diseases
- A history of eye injuries or surgeries
- Diabetes or high blood pressure
- A history of migraines or other neurological conditions
- Taking certain medications that can affect your vision
As we grow older, our eyes become more susceptible to certain conditions. For this reason, Dr. Hanna may suggest regular visual field testing once you reach 40 years old, even if you don’t have any specific risk factors. By staying on top of regular eye exams, including visual field testing, you can help maintain the health and well-being of your eyes for years to come.
