Haag-Streit Octopus 900

Advanced Perimetry for Diagnostic Flexibility

The HAAG-STREIT OCTOPUS 900 is the epitome of advanced perimetry, offering unparalleled diagnostic flexibility for comprehensive visual field analysis, assessment, and patient tracking. Designed to seamlessly integrate into practice environments, it facilitates standard central and peripheral visual field testing with minimal duration, ensuring high patient throughput and effective practice management.

Equipped with full field standard white-on-white perimetry capabilities, the OCTOPUS 900 performs threshold testing in just 2-4 minutes in the central visual field. Its unique 90-degree cupula allows for full 180-degree peripheral testing, enabling disability assessments, binocular driving tests, and more.

  • Comprehensive Perimetry: Addresses major perimetry needs with diagnostic flexibility.
  • Efficient Testing: Performs standard white-on-white threshold testing in 2-4 minutes.
  • Peripheral Testing: Enables full 180-degree peripheral testing for comprehensive assessment.
  • Reliable Results: Automatically recognizes fixation losses for trustworthy outcomes.


OCTOPUS 900 automatically detects fixation losses and adjusts patients accordingly to ensure optimal test conditions and consistently trustworthy results. Its true Goldmann Kinetic perimetry functionality allows for defining kinetic vectors with various characteristics, while user-defined templates aid in generating fast and reproducible results for standard isopters, blind spot mapping, and specialized examinations.

The innovative TOP fast-threshold strategy further enhances efficiency by reducing examination time by nearly 80%, compared to traditional strategies. Tendency Oriented Perimetry (TOP) algorithm systematically considers threshold value correlations in neighboring locations, making it easy for patients to understand the test nature and facilitating quicker testing sessions.

Additional features such as cluster analysis, polar analysis, and results presentation enhance the OCTOPUS 900’s utility and reliability, making it a preferred choice for clinicians seeking advanced perimetry solutions.
