Understanding Visual Field Testing: What It Is and Why It Matters for Your Eye Health

At Tower Clock Eye Center, we are committed to providing comprehensive eye care, including advanced diagnostic tools like visual field testing. This crucial exam helps detect and monitor a range of eye and neurological conditions, ensuring our patients receive the area’s most accurate diagnoses and personalized treatment plans.

What Is Visual Field Testing?

Visual field testing, also known as perimetry, measures your peripheral (side) vision. The test identifies gaps or changes in your field of vision that may not be noticeable during a routine eye exam. By assessing your entire visual range—both central and peripheral—this test helps detect issues that could otherwise go unnoticed.

Why Is Visual Field Testing Important?

Visual field tests are essential in diagnosing and monitoring conditions such as:

• Glaucoma – One of the most common uses of visual field testing, this exam helps detect early signs of vision loss caused by increased eye pressure.
• Neurological Disorders – Conditions like strokes, brain tumors, or optic nerve damage can impact your visual field.
• Retinal Diseases – Disorders affecting the retina, such as retinitis pigmentosa, may show distinct patterns of vision loss.
• Ptosis and Eyelid Abnormalities – Drooping eyelids or other structural issues can obstruct your field of vision.

What to Expect During the Test

Visual field tests are non-invasive and typically performed in-office. You’ll sit at a machine and focus on a central point while lights or patterns appear in your peripheral vision. Each time you see a light, you press a button. Your responses help map out your visual field and identify any blind spots.

At Tower Clock Eye Center, we use state-of-the-art equipment to ensure accuracy, comfort and efficiency throughout your visual field test.

Who Should Get a Visual Field Test?

We may recommend visual field testing if you:

• Have a family or personal history of glaucoma
• Are experiencing unexplained vision changes
• Have been diagnosed with high eye pressure (ocular hypertension)
• Suffer from neurological symptoms such as headaches, visual aura, or sudden vision loss
• Are taking medications that can affect vision (such as hydroxychloroquine)

Routine testing is also part of ongoing care for patients with chronic eye conditions.
