The sensitive Cluster Analysis groups visual field defects along nerve fiber bundles, combining high sensitivity with strong specificity to detect early glaucomatous changes. At the other end of the spectrum, the Octopus 900 provides Stimulus V testing with normative data, ensuring reliable detection of late-stage changes.

The Octopus Polar Analysis puts the optic nerve head in the spotlight by projecting local visual field defects along the nerve fiber bundles onto the optic disc. This enables a straightforward correlation with structural defects when comparing visual fields with OCT. Combining structure and function is key to achieving a comprehensive assessment of glaucoma progression. 

In addition to a comprehensive library of visual field patterns, including the most common glaucoma patterns, Octopus perimeters offer physiology-based G and M patterns for central field and macula testing. These patterns are correlated with a nerve fiber bundle map, enabling targeted testing at the points most critical for structure–function correlation.
