Visual field tests measure the total area that is seen while the eye is directed straight ahead. The total visual field with both eyes open is approximately 180° horizontally and 155° vertically. A visual field of less than 60° will start to significantly impact on a person’s ability to move about within the environment. The Octopus 900 performs standard white-on-white threshold testing in just 2–4 minutes in the central visual field. With its comprehensive test library for central and peripheral tests and its flexible printouts both in Octopus and HFA-format it covers all your clinical needs. Machine based tests aid diagnostics by allowing a detailed printout of the patient's visual field.

The Esterman tests a total field extent that approximates 145 degrees rather than “extends to 160 degrees temporally on both sides.” The Esterman tests (both binocular and monocular) use the same stimulus intensity as the other Humphrey screening tests, which would obviously differ from a threshold test. Se hela listan på eyewiki.aao.org Given the subjective nature of the test, it’s essential to differentiate true, disease-related defects and abnormalities from artifact and noise. Evaluating visual field results from any perimeter can be confusing and daunting at times, especially when attempting to cohesively link all the data together.
