automated perimeter

An automated perimeter is a sophisticated eye test device used to measure a person's visual field, or the area they can see without moving their eyes. It uses computers and sensors to project lights or patterns across a wide area, then tracks how and when the person detects them. This test helps detect and monitor conditions like glaucoma or other neurological issues that affect peripheral (side) vision. Because it is automated, it provides precise, reproducible results quickly, reducing the need for manual effort and enabling eye care professionals to assess visual function accurately.
