Perimeter Priestley Smith
Product Code : EL-LE-12303
Eduscope India is a leading Perimeter Priestley Smith
Quick Answer: The Perimeter Priestley Smith is an instrument for accurate charting of the field of vision, built around a pivoted metallic arc on a vertical stand.
As a scientific instruments manufacturer India resource, it has a circular black disc to read the meridian, with the arc shaped as a semicircle of 330mm radius that can rotate in any direction and be fixed at any position with a tightening screw. A scale and circular chart frame at the back of the disc holds the chart paper in position, and a metallic graduated scale with a movable pin-punch pointer marks directly onto the perimeter chart paper. The arc itself is graduated from 0° to 90° with a movable test object - a white color spot of 10mm diameter painted on a circular disc - that moves along with the arc, while an adjustable chin rest and a detachable leveling bar are fixed in front of the metallic arc for the patient. It pairs naturally with EduScope India's Perimeter, Lister Type for a fuller range of visual field testing instruments.
