perimetry
Perimetry is a visual field test that measures a person's peripheral vision. It helps detect any changes or loss in vision that may indicate eye conditions such as glaucoma, retinal diseases, or neurological disorders. During the test, patients focus on a central point while lights are flashed in different areas of their vision.
The results are plotted on a chart, showing the sensitivity of vision in various parts of the visual field. This information assists eye care professionals in diagnosing and monitoring eye health, ensuring timely intervention if any issues are detected.
