All Octopus perimeters offer the physiology-based G and M patterns for central field and macula testing. They are correlated with a nerve fiber bundle map and thus allow testing the points which are most important for a structure-function correlation.
HFA test patterns
For transitioning from HFA
The Octopus 600 offers standard central field test patterns including 24-2, 24-2C, 30-2, 10-2 that are used on the HFA perimeter. This allows for continuity of testing methodology when switching from a HFA perimeter.
TOP & Dynamic strategies
Fast testing strategies
The TOP and Dynamic strategies test the central field in just 2-4 or 6-8 minutes respectively. While the TOP strategy is more patient-friendly, as it starts in the suprathreshold level, the dynamic strategy is more accurate in identifying single, isolated defects.
White-on-white test
Standard testing parameters
The Octopus 600 perimeter offers white-on-white perimetry with a Goldmann III equivalent stimulus. Also referred to as Standard Automated Perimetry SAP.
For consistent use of testing methodologies and easy delegation, the Octopus 600 allows creation of a custom examination list within the testing workflow. This is convenient and reduces operator errors. For easy communication, each test parameter set can be named according to a clinic’s needs.
