Henson 5000 visual field test for glaucoma

Henson 5000 visual field test for glaucoma

Just had our Henson bowl perimeter overhauled by Hanson instruments. The visual field instrument is part of our excellent range of equipment in the consulting room in Earls Colne near Halstead Essex. A visual field instrument is used to detect early changes in the side of the vision. The edges of the vision are affected by issues such as glaucoma and restrictions in blood flow such as TIAs. A TIA is a temporary ischeamic attack and affects the nutrition to an area of the body, e.g. the eye. Detection of an early field defect can help in the early diagnosis of glaucoma and strokes. Allergan has recently launched an app to show the vision loss related to glaucoma.

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. Binocular field tests are usually done for a DVLA driving test. We can do these for class one only.
