3 INTRODUCTION 3.1 OCTOPUS Perimeter 900 The OCTOPUS 900 is an automatic projection perimeter for the examination of the whole field of sight (90°). The system is divided into an examination element (OCTOPUS 900) and a control unit (notebook computer or PC). The examination element communicates with the external PC via an Ethernet link. The OCTOPUS 900 is controlled using the software installed on the PC. The perimeter may be controlled, if required, from a fully-lit adjacent room. The integrated, automatic patient-fixation control function guarantees the reliability of diagnosis. The OCTOPUS 900 is suitable for both clinical and investigational purposes, as its flexibility is virtually unlimited. Thanks to its spherical, Goldmann-type cupola design, the OCTOPUS 900 tests the entire field of sight (up to 90° eccentricity). The flexibility of this appliance allows it to deal with all perimetry tasks, both in the 30° and 90° range, using kinetic, static or flicker perimetry. New PC and perimetry software can be downloaded and updated by going to www.octopus.ch.

OCTOPUS 900 Service Manual

3.1.1 Housing Optical and electronic components are protected from light and dust by five housing covers. They can be removed in just a few moments for the purpose of servicing. Once the four screws in the back panel have been removed, the panel, hood and both IR covers can be lifted out. The optical unit and electronic components of the OCTOPUS 900 are now accessible. Always disconnect the appliance from the mains power supply before opening it. The removal of housing components must only be carried out by suitably-trained specialists who are qualified and authorized to do so.

3.1.2 Cupola The cupola of the OCTOPUS 900 has a diameter of 600mm, and thus conforms to the Goldmann standard. Test zones with eccentricity up the following levels can be measured: Nasal Temporal Superior Inferior

• • • •

60° 89° 60° 70°

3.1.3 Head rest A wide, ergonomically-designed forehead rest allows the patient to remain in a comfortable position while examination is taking place. 3.1.4 Chinrest with sensors The four buttons on the control panel are used to adjust the chin support, and thus the position of the head. Fine adjustment can also be carried out from the control unit (PC) using the computer mouse. Sensors in the chin rest detect if the patient’s head is correctly positioned. 3.1.5 Refractive lens holder module An automatic swivel arm allows the refractive lens holder to swing in an out during the examination, without having to alter the position of the patient. This swivel arm can be operated either from the control panel or on-screen with the computer mouse. Once the refractive lens holder has been swung in, it can be fine-adjusted to the correct distance with respect to the eye being examined.

!

CAUTION

Always use the control-panel buttons on the device itself or on-screen control from the PC to swivel the refractive lens holder in an out. Do not attempt to move the refractive lens holder manually.

3.1.6 Refractive lens holder Refractive lenses can be used during examinations within 30° eccentricity. The corresponding lenses are inserted before the test begins. The refractive lens holder can be tipped forward by about 25° to make it easier to load the refractive lenses.

3.1.7 Patient-response button The patient-response button is connected to the underside of the head-support mounting (RJ11 jumper cable). 3.1.8 Mains connection The Ethernet connection socket is located at the back of the appliance. Always use a crossed Ethernet cable for a direct PC connection or a straight Ethernet cable for a connection through a network switch (shielded cable of category 5e), designed to transmit reliably at 100MHz. This network connection is electrically isolated, with electrical strength of 4kV, in conformity with IEC / EN 60601-1. 3.1.9 Light sources LEDs are fitted for the purposes of periphery or background lighting, fixation help and stimulus. LEDs do not emit any heat, so no active cooling system is required in this respect. 3.1.10 Light intensities The intensity of stimulus and periphery light is measured by independent light-sensors and compared to the preset default values every time the perimeter is switched on. 3.1.11 Stimulus The stimulus light is projected indirectly into the cupola via a mirror unit. The user-defined programs offer a selection of five different diaphragm diameters (Goldmann I - V). Stimulus intensity-damping is infinitely adjustable via the electronic control system. Stimulus presentations of 100-500ms are permitted. A mechanical lock und optical damping elements are no longer required. White stimulus for W/W perimetry and optional blue und red stimulus for B/Y and R/W are possible. Stimulus intensity is detected by a light sensor, which also serves as a reference point for the system of coordinates for test locations. The stimulus LED has a service life of >20,000h and is thus maintenance-free. 3.1.12 Periphery or background lighting White background brightness amounts to 31.4 or 4asb for W/W perimetry. You can also select a yellow background with 31.4asb for B/Y perimetry. Background brightness is based on two light sources, each fitted with several LEDs. The background LEDs have a service life of >20,000h and are thus maintenance-free. Background brightness is detected by a separate light sensor. 3.1.13 Fixation marks Three different fixation marks can be selected and their brightness infinitely adjusted by electronic means. The light source is a maintenance-free green LED with a service life of >20,000h.

3.1.14 Fixation control The eye being examined is illuminated with IR LEDs, photographed by a CMOS camera and shown on the LCD display. The built-in, automatic fixation-control function guarantees the reliability of diagnosis. Precise positioning of the eye being examined is carried out by motorized fine-adjustment of the chin rest. 3.1.15 Diagnosis data All diagnosis data are transferred via the Ethernet connection to the control unit (PC / Laptop) for processing and saving to a database. The use of a second Ethernet connection (LAN card) allows these data to be exported to a server. Diagnosis data can also be printed out using a printer connected to the control unit. 3.2 Octopus 900 control unit / PC A standard PC can be used as a control unit for the Perimeter.
