Visual Field Testing

Request Appointment

Visual Field Testing is Simple and Accurate, Allowing Us to Gain Insight Into Eye Diseases like Glaucoma and Neurological Conditions Like a Stroke or Brain Tumour.

A Simple But Important Diagnostic Tool

Visual field testing measures your field of vision, and is the gold standard for detecting Glacouma and following its progression. It is a simple, non-invasive test to perform.

What Does a Visual Field Test Measure?
  • How far up, down, left, and right you are able to see without having to move your eyes, neck, or head
  • Visual accuracy across your visual field
  • Responsiveness to various stimuli/light across your visual field
Painless, Non-Invasive, and Accurate

A visual field test does not require any activity that would cause discomfort. It involves placing your head on a cushion and following our instructions as we test various aspects of your visual field. When performed properly, a visual field test can give us important information about your eye health.

When undergoing a visual field test, it is imperative that you provide accurate information regarding what you are seeing. Often, patients will try to “do well” on the test, making the data collected unreliable as a result. So long as you are honest in your responses, the visual field test will produce an accurate result.

What a Visual Field Test is Looking For

A visual field test can provide information on:

  • The development of Glaucoma
  • Various eyelid conditions (ptosis, drooping)
  • Optic nerve damage

Test Performed During a Visual Field Test

A visual field test is quite low-tech in comparison to some of the other testing equipment we have access to, but it remains an important diagnostic tool.

During a visual field test we will perform:

  • Confrontation visual field test – While standing or sitting still, and with one eye covered, we will place objects in your field of vision and ask you to provide feedback on what you’re seeing.
  • Amsler grid test – While looking at a fixed point within a larger square grid, we will ask you to interpret various points on the grid. This test helps us determine visual acuity across various points in your field of vision.

Next Steps

A Visual Field Test is Part of Our Comprehensive Eye Exam

Our eye exams for adults, children, and senior citizens are detailed, leveraging many different types of test – such as the visual field test – and advanced optometric equipment. An eye exam lasts for roughly one hour (more if you have questions) and is typically covered by your vision benefits (OHIP provides coverage for minors and senior citizens). For most people, an eye exam once every 12-24 months is sufficient.

NTOC Testimonials

  • Since 2004, Dr. Peacock and Dr. Amarnath of NTOC have very capably managed my eye care needs in conjunction with my Ophthalmologist. As a regular patient at their clinic, I can attest to their competence and to their hightech equipment. The NTOC Optometrists have an excellent working relationship with the two Ophthalmologists who have privileges at Stevenson Memorial Hospital. This is so important to their patients who are determined to require the next level of eye care. Their staff are very pleasant, friendly and helpful. NTOC is a great place to entrust your eyes.

    J.J. Paul Whiteside, CMA, FCMA, Alliston

  • Dr. Amarnath and Dr. Peacock have been more than accommodating under both our planned and emergency situations. NTOC always provides flexible options and they are always happy to see us. Each visit is a very positive experience. The services and products they provide are comprehensive, but not high-pressured, and they provide service and guarantees that are much higher than industry standards. We totally enjoy and appreciate being their patients and recommend NTOC without reservation.

    Maryann & Gordon Foy, Alliston

  • When I experienced a serious eye condition in 2006, I was very impressed with the knowledge, expertise, and quick response by Dr. Amarnath and his team at NTOC. I was referred to an eye specialist the very same day, and my follow-up care was thorough and efficient, even to this day. This team works with absolute professionalism, and I would highly recommend them to my family and friends.

    Gregg Fullarton, Cookstown

  • I have been a patient of Dr. Peacock since 2002, and find him to be very competent and thorough. Dr.Peacock genuinely listens to any concerns I have about my eyes, and takes the time to enquire with interest about my family. His team is always pleasant, polite and helpful, making me feel very comfortable when I visit the clinic.

    Patricia Murphy, New Tecumseth

  • I was very impressed with my first visit. From the moment I walked in, the staff was more than friendly and she did her best to explain procedures and tests that would be done today. I am a very nervous eye patient and Dr. Peacock did everything to ease my tensions and explain all procedures. When choosing my glasses, I felt very confident in her suggestions and was very pleased with the time taken to ensure the correct choice and fit. All in all, I am thrilled with my choice of optometrist office. And, I look forward to my next visit. Something I have never experienced before. Thank you.
