The Octopus 900 kinetic perimetry gives all the advantages a manual Goldmann perimeter offers and beyond. Stimulus sizes I to V and intensities 1a to 4e are defined using Goldmann type sliders. The angular velocity determines stimulus speed and both a white and red stimulus are available.
Norm isopters offer guidance on where to place vectors and on how to interpret patient responses. The dark and light bands represent 25–75% and 5–95% of healthy normals of the same age respectively. Coordinates are optionally displayed to guide vector placement.
Reaction time vectors are placed in the patient’s visible area. The average time between stimulus appearance and patient response is then considered the patient’s reaction time and patient responses are adapted accordingly. This better reflects the actual isopter size.
The kinetic perimetry on an Octopus 900 functions similarly to a drawing program. Stimulus trajectories are typically defined by drawing straight vector along, which the stimuli move at constant speed. Static points are available for spot checking. To form isopters, patient responses are connected manually or automatically.
For full flexibility, any shape of stimulus trajectory is possible using a guided vector. For even more control, stimulus can be manually guided by using the mouse like the handle in a manual Goldmann perimeter.
Kinetic templates standardize testing while maintaining full testing flexibility to individualize whenever needed. Translate clinical testing methodology into an individual template or alternatively, benefit from available templates .
