VISUAL fIELD ANALYZER AP-50

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.

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

Elliptically shaped measurement bowl requires lower test roomillumination conditions. Electronically controlled backgroundillumination assures stable measurement conditions.

Standard test fields and conditions

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

Defect progress analysis

Regression analysis module allows user to track changes in field of vision in time, using easy for interpenetration graphs. Multiple examination results of the same patient can be used for the analysis. Regression curves can be presented i absolute dB values, in relation to hill of vision or age normative values or particular global parameters like PD or AD. Analysis of the data can be limited to particular area of vision field like periphery or center, or can cover entire tested field of vision.

Multiple methods of examination data presentation

To better visualize possible vision field defects user has reach set of data presentation modes available to choose from. Result maps can be displayed as:
– numeric values, pattern grade or grey scale
– absolute values in dB, as relative to hill of vision, age normal related, defect probability
– defect curve (Bebie graph)
– normalized vales

Data safety

Automatic backup file generator frees the operator for creating copies of examination data.Auto-backup function can start automatically with period and in location defined by the user.This function assures safety of patient records.
