Product code: VFAP50

The AP-50 is a lightweight desktop auto perimeter, ideally suited for glaucoma diagnosis and busy mobile clinicians.

The AP-50 uses LED back projection of stimuli in white colour, and offers a wide range of strategies, test fields and 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 includes regression analysis and standardised presentation and printing of examination results.

The AP-50 Auto Perimeter is compatible with any PC computer running Windows.

Small device size with extensive features​ 

The elliptically shaped measurement bowl significantly reduces the size of the AP-50, yet the diagnostic value is comparable to a full field perimeter

Easy to use interface

Requires only minimal training to operate and connects to any Windows PC (PC sold separately)

Compact and lightweight design

Weighing only 9kg, the AP-50 is an ideal desktop clinical tool which can be easily transported, set up and used, including in remote sites.

Less affected by ambient light conditions

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


Standard test fields and conditions

Tests include central 30, central 24, and macula; all tests allow for easy data comparison with other perimeter systems and dedicated glaucoma tests are included

Binocular testing

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