The Automated Confrontation Visual Field Tester is an automated LED gross confrontational visual field tester. It is cost effective, easy to use and fast (both eyes can be tested in less than a minute). The ACVT is more accurate and sensitive than using finger confrontation methods. The ACV tester consists of a black unit measuring 12 cm by 17 cm. Four 1.0 mm red LEDs are positioned 11.25 cm apart, which results in an angular separation of 15 degrees when the device is 60 cm from the patient. The tester is powered by 2 AA batteries.
