VS-V GT Medical Vision Screener (with Glare Test) Vision testing created to test basic visual functions as well as contrast and glare sensitivity capabilities. Testing these additional functions allows you to perform procedure code (CPT) 92284 Dark Adaptation Exam for diagnosis of: 365.11 – Glaucoma – Open Angle – Primary 366.16 – Cataract – Nuclear Sclerosis 366.17 – Cataract – Mature 746.85 – Cataract – Senile Mature Fulfilling the Dark Adaptation Exam needs of ophthalmologist the VS-V GT Medical Vision Screener is designed for rapid yet accurate evaluations. The VS-V GT Medical blends technological convenience with more than 80 years of vision testing research, expertise and excellence. Like its predecessors, the VS-V GT features several unique competitive advantages—such as testing in reflected light rather than with backlit targets to mirror everyday visual function. Now available with Keystone View's Visionary Software, which allows one to control the Vision Screener and record results with simple clicks of the mouse.
