The ESAW Perimeter Priestley Smith PPP-399 is a specialized ophthalmic instrument designed for accurate charting of the visual field. It features a semi-circular metallic arc (330 mm radius) mounted on a sturdy vertical stand, allowing full rotation and precise fixation with a tightening screw. The arc is graduated from 0° to 90°, with a movable 10 mm white test object for visual field mapping.

A circular black disc houses a graduated scale and chart frame to hold perimeter chart paper securely. A movable pin-punch pointer marks the readings directly on the chart. For patient comfort, it includes an adjustable chin rest and a detachable leveling bar to ensure accurate alignment during testing.

This affordable perimeter for labs and clinics in India is built with export-quality materials, making it ideal for ophthalmology training, medical diagnostics, and vision research across India, Africa, Europe, Asia, and the USA.
