Perimetry

Perimetry is a visual test that measures a person's field of vision. It determines how well you can see in different directions, including peripheral (side) vision, which is crucial for detecting vision problems. During the test, you focus on a central point and signal when you see lights or objects appear in your peripheral vision. This helps doctors identify conditions like glaucoma, brain injuries, or diseases that affect the optic nerve. Overall, perimetry is an essential tool in assessing eye health and diagnosing potential visual impairments.
