Haag-Streit Octopus 300
Haag-Streit · Model Octopus 300
The Octopus 300 is the compact perimeter for every glaucoma practice. It even fits in a corner and produces accurate results without a dark room. The Octopus 300 incorporates both Short-Wavelength Automated Perimetry (SWAP) and Flicker Perimetry for early glaucoma detection. Central field standard white-on-white perimetry Automatically recognizes fixation losses Fast-thresholding strategy Cluster analysis - high sensitivity and specificity EyeSuite Perimetry software - included Octopus Blink Control Pupil position control Automated eye tracking Contact control Printout and graphics representation results.
Key tips
- ·Verify laser output with a real power meter, not the unit's own display - the display can drift independently of true output.
- ·Take "the image looks a little off" reports seriously - optical alignment drift is usually gradual, not sudden.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Projection / stimulus fault
HighSymptoms: Stimuli not projected, wrong intensity, uneven bowl illumination, fixation target not visible.
Root cause: Projection / bowl-illumination LED or lamp at end of life, a filter / shutter fault, or the projection mechanism.
Fixation / gaze-monitoring fault
MediumSymptoms: Excessive fixation losses, the eye / video monitor blank, gaze check will not calibrate.
Root cause: Eye-monitor camera / IR illuminator, or head / chin positioning.
Patient-response button fault
MediumSymptoms: Response-button presses not registered.
Root cause: Response button or cable fault.
Chin-rest / head-positioning drive fault
MediumSymptoms: Chin rest / trial-lens holder will not move to command.
Root cause: Positioning drive motor or its control.
PC / data / printer fault
LowSymptoms: Tests will not save, transfer (EyeSuite) or print.
Root cause: PC, network, or printer.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Optical alignment / calibration check
- ·Lamp or laser output verification
- ·Annual full PM
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Projection / stimulus fault
- Confirm the bowl illumination is even and the fixation target is visible.
- Replace the projection / bowl-illumination LED / lamp if dim or out.
- Run the instrument self-test / calibration.
- Check the filter and shutter operate.
- Escalate a projection-mechanism fault to Haag-Streit service.
Symptom: Fixation / gaze-monitor fault
- Confirm the patient is correctly positioned with the correct trial lens.
- Clean the eye-monitor camera window.
- Re-run gaze / fixation initialization.
- Check the eye-monitor camera and IR illuminator.
- Replace the camera module if calibration still fails.

The firm recalled the device after learning of a possible deviation in the stimulus luminance of the Perimeter OCTOPUS 101.
- RECALL
Currently there is a possibility, at the start of the perimetry examination, for the background illumination of the cupola not to turn on. If no illumination of cupola occurs, data obtained from the examination could provide the doctor with results that would appear to be better than actual.

A patient record may be linked to an incorrect/inconsistent set of calculation results under specific circumstances when using EyeSuite Software version i2.000.
- RECALL
During the creation of the Lenstar LS 900 software, the ability to perform a manual adjustment of the retinal thickness measurement was not disabled for products targeted for US distribution. The current software installed allows the user to manually alter the retinal thickness measurement, which could modify the automatic axial eye length measurement resulting in the selection of an incorrect in
