Frey AP-50 Visual Field Analyzer

AP-50 is a desktop model, lightweight and fully featured modern static automated perimeter ideal for glaucoma diagnosis and specific requirements of occupational medicine and busy mobile clinicians. AP-50 uses LED back projection of stimulus in white color, and offers a wide range of strategies, test fields and reach set of test parameters to assure quick and precise measurement. Control of fixation is performed automatically using the built-in camera or by controlling the position of the blind spot. Built-in data analysis include regression analysis and standardized ways of presenting and printing examination results. Perimeter AP-50 can work with any PC computer running the Windows operating system.

Description

Reduced device size thanks to novel measurement bowl design

Elliptically shaped measurement bowl realizes significantly reduces size of the device yet diagnostic value of AP-50 is comparable to full field perimeters. Full central 30 degree of patient vision with extension to 50 degree temporally allows precise test nasal step where early glaucoma often commences early in the disease progression.

Small size, compact and light weight

AP-50 dimensions of only 548 x 382 x 450 mm and weight only 9kg makes the device an ideal desk top clinical tool which can be easily transported, set up and installed anytime, anywhere including remote sites.

Less demanding for ambient light conditions

Elliptically shaped measurement bowl requires lower test room illumination conditions. Electronically controlled background illumination assures stable measurement conditions.

Standard test fields and conditions

Standard test fields like Central 30, Central 24, Macula are available all allow for easy data comparison with other perimeter systems. Precise testing in nasal step dedicated glaucoma tests are included.

Binocular testing

AP-50 fulfils specific visual field testing requirements for drivers and occupational medicine. Measurement range covers up to 160 degrees temporally, and both eyes can be tested simultaneously.
