What is Sita fast test?

Purpose. In Humphrey visual field (VF) testing measurements from SITA Fast (Swedish Interactive Testing Algorithm) are thought to be more variable than those from SITA standard, yet some clinical centers routinely use SITA Fast on patients because the test is quicker to administer.

Is Sita fast full threshold?

Simply put, SITA testing is quicker for patients (approximately 50% faster than testing with the Full-Threshold strategy), because this testing strategy adapts throughout the test in response to patients’ performance.

What is SITA perimetry?

Ann Arbor, MI-The Swedish Interactive Threshold Algorithm (SITA) is one of the newer generations of perimetry basic detection devices used in glaucoma to evaluate visual fields. The others are short wavelength automated perimetry and frequency doubling technology.

What does Hvf 24 2 mean?

24-2: Measures 24 degrees temporally and 30 degrees nasally and tests 54 points. Used for neuro-ophthalmic conditions and general screening as well as early detection of glaucoma. 30-2: Measures 30 degrees temporally and nasally and tests 76 points. Used for general screening, early glaucoma and neurological conditions.

What does ght outside normal limits mean?

GHT outside normal limits is displayed when at least one zone is at p <1%. This finding has been show to have 94% specificity. 11. GHT borderline is displayed when the p value is between 1% and 3%. Generalized depression indicates that the most sensitive test points are less than 50% of normal.

What is threshold in perimetry?

The limits of the visual field are mapped to lights of different sizes and brightness. With threshold static automated perimetry, a computer program is selected. The most commonly used one tests the central 30° of the visual field using a six degree spaced grid.

What is foveal threshold?

Foveal Threshold is the minimum amount of luminance increment on a uniform background that can be detected by the patient at coordinates 0,0 (relative to the center of the patient’s fixation). See Section C. 8.26. 4.1.

What does Sita stand for in aviation?

Société Internationale de Télécommunications
SITA or Société Internationale de Télécommunications Aéronautiques, was founded in February 1949 by eleven airlines in order to bring about shared infrastructure cost efficiency by combining their communications networks.

What is borderline glaucoma mean?

For mild or borderline glaucoma—meaning an optic nerve that looks somewhat suspicious but still functions—your doctor may want to monitor you indefinitely, until the condition changes or worsens, and then begin treatment. Doctors use the term “glaucoma suspect” to describe people with borderline findings.

Which is better SITA Fast or standard visual field test?

The standard test is better for early detection, while the SITA-Fast test tends to show variable results and is less sensitive. 1 The fixation losses are also noted here. Visual field testing is an important diagnostic consideration in the evaluation of patients with many different types of pathologies.
