How do you read visual field results?
The visual threshold is the intensity of stimulus seen 50% of the time at each location. The threshold values of each tested point are listed in decibels in the sensitivity plot. Higher numbers mean the patient was able to see a more attenuated light, and thus has more sensitive vision at that location.
What is a Henson eye test?
Allergan has recently launched an app to show the vision loss related to glaucoma. Henson. Above is an image for our Henson 5000 bowl perimeter. The instrument can be used to screen one eye at a time or for both eyes together. The test for both eyes is called a binocular field test.
What is a Henson Field Analyser?
The Henson 9000 visual field screener is the perfect tool for glaucoma screening and management, enabling eye care professionals to detect glaucoma and monitor progression. The 9000 offers sensitive, specific and fast suprathreshold and threshold screening.
What is a Henson 9000?
The Henson 9000 is a compact, easy-to-use perimeter for detecting and monitoring changes to visual fields. It features innovative, time-saving tests and analytical tools that enhance patient experience and practice efficiency. Tests can often be extended to include detailed mapping of the central 10 degrees.
What is a nasal step visual field defect?
Nasal step defects are caused by optic nerve disorders that affect the long, arching axons that originate temporal to the macula, entering the disc superiorly or inferiorly. A nasal step may begin as a small depression above or below (and respecting) the horizontal meridian in the nasal visual field (see Figure 3–8A).

Why choose the Henson 9000 for threshold testing?
Threshold testing accuracy and speed are no longer mutually eclusive. Over and above all the advantages of Henson screening technology, the Henson 9000 also allows you to conduct the standard threshold tests used in the detection and management of glaucoma.
