1. A medical test that measures the full extent of the visual field, including peripheral vision, typically used to detect eye diseases such as glaucoma.
Usage: medical/ophthalmology; also called visual field testing

Examples

• The ophthalmologist ordered perimetry to check for signs of glaucoma.
• During perimetry, the patient looks straight ahead while lights appear at different locations in the visual field.
• Regular perimetry is important for monitoring patients with a family history of glaucoma.
• The results of the perimetry test showed a slight defect in the patient's peripheral vision.
• Automated perimetry has become the standard method for assessing visual field loss in clinical practice.
