Patient focused – improved patient comfort
Visual field testing is a joint enterprise between clinician and patient. Visual field testing, otherwise known as perimetry, is a team effort. A patient who is well supported, and where every effort is made to maximize comfort, improves reliability in visual field testing. This increased reliability in visual field testing translates to greater accuracy and efficacy in diagnosis and management for the clinician. In turn, this improves patient outcomes and satisfaction throughout the patient journey, which may be decades long. Frey has delivered improved patient comfort with a chinrest design focused on comfort and stability. The patient’s head is supported throughout the examination. The AP-300 has improved ventilation for the patient, which reduces stress and improves patient comfort.

Rapid Testing Times

Efficient testing is reliably delivered with screening and fast threshold strategies and enhanced fixation methods. Patients with advanced visual field loss are supported with the use of pattern calibration and neurological test methods.

Modes of Operation

Static Test Mode

The AP-300 emits motionless stimuli of variable luminance in order to determine a patient's threshold. There is a dim light in a specific location, and if the patient cannot see it, the intensity of the stimulus increases. The patient’s responses are then compared to those from an individual in a control group who is of an equivalent age.
The exam is defined by Test and Strategy, all stimulus colors and sizes are available for the static tests, and the results are more reliable and of a higher quality.


Kinetic Test Mode
A dedicated test strategy
The test involves a stimulus with a fixed size, intensity, and speed that is moving from the periphery to the centre of the measurement bowl. The test is repeated with different stimulus sizes and intensities in order to define unique isotopes.



Automated Kinetic and Static Perimeter with Embedded PC with Mount with Monitor AP-300 frey - us ophthalmic
Static Test Parameters
Two new parameters can be configured:
  • Stimulus Size
  • Stimulus Color
The backlight illumination color is white for all of the tests, except for the blue on yellow test. For the blue on yellow test, the size of the stimulus is Goldman V.
It is important to select the appropriate test strategy and we test almost twice as many points than our competitors for the same field of vision. In addition, the AP-300 provides a fast scan and smart threshold that further improves testing accuracy.

Kinetic Test Parameters
Kinetic testing is selected by the Kinetic strategy.
  • Any parameters that are not applicable for the kinetic test are disabled automatically.
  • All of the parameters for the test are defined on the test screen level.

Kinetic Test - Results
The Kinetic test results are presented in the form of isotopes, with each one in different colour.
Each isotope links points of the patient’s response to the stimulus entering the sensitive area.

Targeted Perimetry
Perimetry examination results can be presented over a fundus image. Furthermore, the orientation of the stimulus position is calculated using fovea and blind spot position, but each of these have to be marked by the operator.

Fundus Overlay Function
This is a unique approach that allows selective retinal areas to be tested. The stimulus locations are set based on the patient’s fundus image, while the area and density of the test points are set manually.

Fundus Overlay View
The Automated Perimeter software allows users to overlay the exam results with the fundus images that are taken by the fundus camera. In order to get the overlay, after selecting the option “Fundus Overlay”, load the fundus image from the file or select the image from the ones that have already been saved.
The next step is the selection of two orientation points, which are used for the calculation of positions for the exam results. These points are a fovea and a blind spot. Press the button marked “Fovea,” and click the fovea position on the fundus image. Next, press the button marked “blind spot,” and click the blind spot position on the fundus image. The exam results are now displayed on the fundus image. The overlay can then be saved by using option “Save overlay”.

Fixation Control
AP-300 Automated Perimeter has two mechanisms of fixation control.

Heijl-Krakau Method
This is a classic method that checks the blind spot position by assessing a total of 11 points randomly to ensure that the position of the eye is correct.

Method of Eye Position
The AP-300 facilitates fixation analysis with the use of a video camera that allows the pupil to be constantly monitored. The advantage of this method is that it rejects the patient's responses if there is no fixation.


Automated Kinetic and Static Perimeter with Embedded PC with Mount with Monitor AP-300 frey - us ophthalmic
Reliability
Reliable automated fixation control supports the patient and clinician with a built-in camera and automated eye tracking. This increases the repeatability and reliability of the data capture.

Automatic Pupil Detection
If the automatic method of fixation monitoring is used, the software will detect the current position of the eye. There is no need to keep the eye in the center of the image during the test, although it is still important that the patient looks into the fixation point all the times. The eye positioning control feature can be obtained from the screen, from the joystick, or through the software. In addition, the chinrest can be moved up – down and right - left.

Advanced Techniques
Previously, glaucoma was not diagnosed until the disease was in its advanced stage. Currently, we have new technologies that offer early detection of this condition.

The Blue Perimeter Yellow (B-Y)
Blue perimeter yellow, also known as automated short wavelength perimetry (SWAP), demonstrates an enhanced ability to detect early visual field loss in comparison to standard white-on-white (W-W) perimetry.

Flicker (Critical Fusion Blink)
Glaucoma affects sensitivity to blinking lights.
FFC analyzes a patient's ability to see alterations of light to dark stimuli in different locations of the visual field.
It also measures early neuronal suffering, thereby detecting glaucoma in its early stages.

Single Printout
AP-300 utilizes the simplest form of print, which contains one big graphical map representing the exam results. This will be printed in the same form that is chosen on the "Results" screen in "Single mode". When "Single mode" is not selected, the dB level map in grey scale will be printed by default. The advantage of the "Single printout" option is the very high readability of the print.

Automated Kinetic and Static Perimeter with Embedded PC with Mount with Monitor AP-300 frey - us ophthalmic
Multiple Printout Options
Users have the option to use 1 out of 7 available printout standards. HFA type printouts are predefined and static perimetry standard printouts are also available (FREY, Medmont, etc.). The printouts are in grey scale and in color.

Pattern Calibration
The AP-300 was designed to reduce test duration for patients with significant loss of vision field.
Earlier examination can be used as the starting point of a new test.
"Pattern" examination defines the starting point for a new examination. In addition, blind stimulus locations from "pattern" examination are tested with the highest stimulus intensity.
All test parameters are identical to the reference exam and the parameters are selected during the start of a new test in the “Test parameters window”.

Pattern Multiple Driver Test Options
5 different driver test programs
Visual monitoring of both patient’s eyes

LED LIGHT SOURCE
  • All AP-300 light sources are LEDs
  • The system is maintenance free
  • It demonstrates high light source stability over the time
  • Real white on white perimeter
  • White stimulus 4000K color temperature
  • White background illumination 4000K temperature
  • HFA devices use CCFL lamps for background illumination and halogen bulb for stimulus



Self Diagnostic
Before and after each test, the AP-300 performs a self-diagnostic cycles in which:
  • Stimulus intensity is verified by an internal sensor.
  • Any error related to mechanical misalignment and light source intensity drift is minimized.
  • Dust or dirt collected in the optical path is detected.
  • Background illumination is stabilized in order to allow the test to start.
  • Ambient light influence is minimized.

Reliability
Reliable automated fixation control supports the patient and clinician with a built-in camera and automated eye tracking. This increases the repeatability and reliability of the data capture.

Regression Analysis – Static Perimetry
The AP software is equipped with a set of options that allow a user to observe changes in a patient’s vision in many different ways. The first possibility is the simple comparison of results, which was described in the previous section. A second possibility that is much more advanced, is regression analysis which helps the user observe the regression or progression of a patient’s vision over time.
At least two patients’ exam results are needed to perform regression analysis. The exams should be conducted using the same strategy, but on different days.
The patient’s name, age, and the eye that was tested will be listed on the left top part of the screen. A combo box located on the middle top portion of the screen lets the user choose one of five parameters that will be used to calculate and display the regression graph. The following parameters can be selected:
  • Decibel level
  • Hill of Vision decibel level
  • Age Normal Deviation decibel level
  • Pattern defect (PD)
  • Average defect (AD)

The combo box is available when ‘Single mode’ is selected (on the right bottom of the screen). ‘Combo mode’ displays all five modes of the regression graphs together.

Test Editing
This function allows a user to define a custom test field. It is especially convenient for cases where only a part of the patient’s visual field should be examined, for example, the area where visual field loss was observed during earlier examinations. Using a custom test field in this manner can decrease both the patient’s discomfort and the examination time.
The affected eye (left or right) and the test field name that will be used as a pattern should be selected before test editing begins. The following test fields are available by default:
  • Central 22˚
  • Central 30˚
  • Driving
  • Full
  • Glaucoma
  • Macula
  • Peripheral
  • Wide

The combo box is available when "Single mode" is selected (on the right bottom of the screen). ‘Combo mode’ displays all five modes of the regression graphs together.

Hill of Vision Probability Map
A "Hill of vision probability map" shows the probability of Hill of Vision defects for every single point of a field. The probabilities are calculated from the differences between the theoretical and calculated hills of vision. The lower the probability, the bigger the defect in the field of vision.

Complete Analysis Modes
The AP-300 reliability and functionality is reinforced by complete analysis modes. These analysis modes are backed up by world population statistics.
The shaded maps have enhanced 3D function.


Age Normal Map
An Age Normal map displays the differences between the age normal values and the values obtained from the test. Therefore, the Age Normal map reflects the difference between the theoretical dB level map and the measured one.
Accordingly, an Age Normal map can be drawn in the following formats: numerical, grey scale, color scale, pattern scale, and 3D graph.
