Maintaining good eye health goes beyond routine eye exams and vision correction. Visual field testing is a valuable diagnostic tool that plays a crucial role in detecting and monitoring various eye conditions. In this article, we’ll explore what visual field testing is, what to expect during the procedure, and why it matters for your eye health.
Understanding Visual Field Testing
Visual field testing, also known as perimetry, is a diagnostic procedure that assesses your peripheral vision or side vision. It measures the extent and quality of your visual field, helping optometrists detect abnormalities or signs of eye diseases that may not be noticeable in a regular eye exam.
Why Visual Field Testing Matters
Visual field testing is essential for several reasons:
Detecting Eye Diseases: Visual field tests can identify eye diseases such as glaucoma, which often affect peripheral vision before causing central vision problems. Early detection allows for timely intervention and treatment.
Monitoring Progression: For patients with conditions like glaucoma or macular degeneration, visual field testing helps monitor disease progression over time. It allows optometrists to adjust treatment plans as needed.
Assessing Neurological Conditions: Visual field tests can also aid in diagnosing neurological conditions like brain tumours or multiple sclerosis, which can affect peripheral vision.
What to Expect During Visual Field Testing
Visual field testing typically involves the following steps:
Preparation: You’ll be seated in a dimly lit room and asked to focus on a fixed point, usually a light in the centre of a dome-shaped device.
Testing: During the test, small lights or dots will appear at various locations within your peripheral vision. Your task is to indicate when you see these lights by pressing a button or verbally responding.
Each Eye is Tested: The test is usually performed separately for each eye, and the results are then combined for a comprehensive assessment.
Duration: The test may take around 15-30 minutes to complete.
