Automated Confrontation Visual Field Tester (ACV)
The Automated Confrontation Visual Field Tester (ACV) is an automated LED gross confrontational visual field tester that is cost effective and easy to use testing both eyes in less than a minute. The ACV is more accurate and sensitive than using finger confrontation methods. The AVC was developed by Jeffrey Cooper, MS, OD, FAAO, Clinical Professor, SUNY State College of Optometry; evaluated and standardized by Sherry J. Bass, MS, OD, FAAO, Distinguished Teaching Professor, SUNY State College of Optometry.
The ACV instrument is a compact, black, rectangular instrument with a 1.0-mm red light-emitting diode (LED) positioned 11.25 cm apart at each of its four corners with a fixation hole at the center. The device presents automated, randomized patterns of lit LEDs and the patient is asked to identify the number of lights seen. The eye care professional views the tested eye though the device to ensure fixation on the center and is able to validate the patient’s response with the four indicators on the rear panel while the patient identifies the presentations of the random LED pattern on the front. Determination of visual field loss is an important part of any comprehensive eye examination.
The ACV measures approximately 4.75" x 6.75" (12 cm x 17 cm) and is powered by 2 standard AA batteries.
