A Visual Field Test is a diagnostic procedure used to measure a person's peripheral vision. During the test, patients look straight ahead while lights or objects are presented in their side vision. The goal is to identify any blind spots or areas of reduced vision, which can indicate various eye conditions or neurological issues. This test is commonly performed by eye care professionals, such as optometrists or ophthalmologists. It helps in diagnosing conditions like glaucoma, retinal diseases, and neurological disorders. Early detection through visual field testing can lead to timely treatment and better management of these conditions.
