What is Sita faster?

What is Sita faster?

SITA™ Faster is the newest addition to the SITA family of testing strategies for the Humphrey® Field Analyzer 3 (HFA3) perimeter. b. SITA Faster testing takes about two-thirds of the time required by SITA Fast and about half the time required by SITA Standard.

How much is a visual field machine?

The goal of advances in visual field testing is to provide accurate, reproducible information in a patient-friendly amount of time, and the current gold standard is static automated threshold perimetry. Such a machine costs $25,000 to $30,000, requires electricity, and is not portable.

What is the Humphrey visual field test?

The Humphrey visual field is a diagnostic test to measure visual fields, or perimetry. The Humphrey visual field test measures the entire area of peripheral vision that can be seen while the eye is focused on a central point.

What is a 30-2 visual field test?

30-2: Measures 30 degrees temporally and nasally and tests 76 points. Used for general screening, early glaucoma and neurological conditions.

What is Sita visual field?

Purpose. test visual field loss. Usually referred to as SITA, the Swedish interactive thresholding algorithm is a method to test for visual field loss, usually in glaucoma testing or monitoring.

What is Sita standard?

4. The Swedish Interactive Thresholding Algorithm (SITA) Standard was developed for the Humphrey Field Analyzer (HFA; Carl Zeiss, Meditec) in the 1990s and allows VF testing to be performed in about half the time taken by older full-threshold strategies,5-7 with no significant decrease in precision.

What does a Phoropter do?

A phoropter is an instrument used to test individual lenses on each eye during an exam. If, during an eye examination, your doctor has discovered a vision problem like nearsightedness, farsightedness or astigmatism, it’s likely that one of the next steps you’ll take will involve a phoropter.

What is Octopus visual field?

The Octopus Polar Analysis projects local visual field defects along the nerve fibers to the optic disk and displays them oriented as structural results. This makes structure-function correlation almost intuitive. Polar Analysis is available in both single field and trend view.

Are your eyes dilated for a visual field test?

Part of a glaucoma examination is formal visual field testing, where your peripheral, or side vision, is tested. Ideally, your eyes are not dilated during this test.

What is a 120 point visual field test?

Esterman visual field perimetry is a binocular testing method which is also available on the HFA. The test consists of 120 white test points shown with equal, non-adjustable suprathreshold light intensity of 10 dB and examines more than 130° of the field.
