Manual Organisation
1. Manual Organisation This manual is divided into four sections: 1. Introduction and Device description, 2. The installation of the software and the perimeter, 3. The set up for and performance of a test, and the saving and reviewing of the results, and 4. A reference section that elaborates on the introduction given in 2. In discussing the normal interaction between the software and those involved in a particular operation, test or test review, the manual uses the term Clinician to refer to the person operating the equipment, and Patient to refer to the person undergoing the test. The manual describes the M700 USB and M730 USB Automated Perimeter instrument models and software upgrades of all Automated Perimeters to Studio 5. Software Conventions The term Application Button refers to the circular button in the top left of the menu bar. This button can have different icons but is always in the same position on the ribbon bar. When navigating the application button menu we use the following format: Application Button > Import.
When referring to menu selection, the terminology Home > Patient > New means click on the Home ribbon bar tab, then look for the Patient group on the ribbon bar and click on the New icon. This format conforms to the Tab > Group > Action system for identifying menu items in a ribbon bar menu system.

Medmont Automated Perimeter
Introduction
2. Introduction The Automated Perimeter software is designed as a component of Medmont’s integrated clinical environment called Medmont Studio. Medmont Studio is an extensible software framework that allows the controlling software for different medical instruments to be fully integrated into a single working environment. See the Medmont Studio documentation for help on installing and using the Studio environment.
Variants The Automated Perimeter may be configured at purchase as a number of optional variants. M700 USB C standard model incl. CCD camera for fixation video monitoring. M700 USB CR, additional Red light perimetry @650nm M730 Focus Max 30 degree field, incl. stray light shroud
Intended Purpose The Medmont Automated Perimeter performs rapid and reliable screening and threshold tests of visual fields, while providing comprehensive control over the test and detailed information on its progress. The clinical applications of visual field testing using the Automated Perimeter can include tests for Glaucoma, Flicker Perimetry, Binocular Testing (including Driving Tests), Neurological Testing, Macula Testing, Peripheral Vision Testing and others. Easily followed instructions enable a clinician to quickly perform accurate visual field tests, as well as providing the ability to easily design custom fields and tests. Testing of the visual field is carried out using the technique of static perimetry, with the stimulus targets being a set of rear illumination Light Emitting Diodes (LEDs). In the text the LEDs are referred to as light points. Testing may select from two fields of different coloured stimuli, one green set and one red set (variant R model).

Introduction
Fixation performance is monitored by the Heijl-Krakau technique, with random stimuli presentations in the blind spot or (optionally) using continuous video tracking of the patient’s iris. The patient's fixation performance is continuously displayed to the clinician both statistically and visually. The Medmont Automated Perimeter shall only be used as described in this manual and only for the intended purpose.

Clinical Results, Accuracy and Age Normals The Automated Perimeter is delivered to the end user quality tested and calibrated as per specifications. While the device has exceptional long-term stability, it is not the responsibility of Medmont to police the accuracy of the device after delivery. The device is calibrated and referenced against the Medmont Age Normal standard displayed as a dB scale. Electrical Safety of System To ensure the safety of the Automated Perimeter system, all associated equipment connected to it must be compliant to EN/IEC60950 and powered by an isolation transformer compliant with medical standard EN/IEC60601-1, UL2601 or CSA22.2#601-1. Any open communication port on the PC must be covered with provided port covers when the device is used in a patient environment. When networking to another computer, either the use of a network device with electrical separation of I/Os or wireless network may be used. Please contact your distributor, as network performance may be affected. Radiation The Automated Perimeter emits radiation in the visual range in the distinct wavelength of 565nm. The levels of intensity of this illumination are below any levels known to be hazardous. Electromagnetic Interference Strong electromagnetic interference from unprotected devices or portable and mobile RF communications equipment or mains disturbances (voltage dips, transient surges) or electrostatic discharge may affect the performance or results of the Automated Perimeter. Avoid using the device while such high interference is present. See Troubleshooting on page 131 for particular effects and solutions. The device is compliant with medical standard 8
