Evaluation of the Preferential Hyperacuity Perimeter (PHP) Device, for Testing Intermediate AMD Patients, During Routine Eye Clinic Operation

Principal Investigator

Richard Rosen, M.D.

Enrollment Status

Completed

Objective

To evaluate the fitness and validate the ability of the Notal Vision Macular Computerized Psychophysical Test (MCPT), a Preferential Hyperacuity Perimeter (PHP) Professional device, to detect CNV patients and differentiate them from intermediate AMD patients in a better manner than does the Amsler Grid.

Study Results

One hundred fifty patients participated in the trial. The PHP had greater sensitivity, although with a relatively high rate of false-positive results for healthy individuals, than the Amsler grid in detecting AMD-related lesions.
