AP-600 Automated Perimeter is a modern diagnostic device for fast and precise testing of a patient's visual field utilizing either static or kinetic perimetry one of many available test strategies. For static perimetry patient’s visual field is assessed by briefly projecting a stimulus of known size, brightness, and location on the inside surface of a roughly hemispherical bowl. Bowl illumination is automatically controlled to establish a desired contrast between the stimulus and the area around it. AP-600 enables to define the sensitivity threshold of the retina in a given area, as well as to make a fast screening test. Perimeter software has built-in many internal mechanisms that increase the reliability of the test results. Testing of a patient is performed automatically, and detailed information about the test progress is continuously presented to the operator on the screen. The friendly and easy user interface allows intuitive movement over available options. The user can view and analyse test results in many different presentation methods including regression analysis. The patient's fixation performance is monitored by one of two possible techniques: One is the Heijl-Krakau technique, with random stimulus presentation in the blind spot region. The second one is based on the built-in digital camera allowing eye-detection during examination and during adjusting the patient's position. Due to auto-detection of the pupil position, it allows a continuous automatic control of the fixation. The patient’s fixation performance is continuously presented to the operator in both cases.
