Perimeter (Field Vision Test)

Perimetry is a visual field test of the eye that checks for problems of peripheral (side) vision. Peripheral vision is used primarily for detecting objects and for directing central vision so it is possible to see those objects in detail.

A loss of peripheral vision results in a condition called tunnel vision and can lead to legal blindness. Severe glaucoma causes the loss of peripheral vision. Advances in automated perimetry have reduced testing times and increased accuracy in visual field testing.

The Octopus® 600 extends the successful HAAGSTREIT product range of visual field analyzers combining the Pulsar method for early glaucoma detection and standard whiteon-white perimetry for long term follow-up in one compact and standalone device. It is the first visual field analyzer that performs standard white-on-white perimetry on an integrated flicker-free screen, using TFT and LED technology
