20 wrz 2024 · Among the most widely used VF tests are the 24-2 and 24-2C. The 24-2 exam is derived from the 30-2 protocol and evaluates the central 24 degrees of the retina with fixation centered on the fovea. It has become a standard tool for detecting defects that could indicate glaucoma or other neuro-ophthalmic conditions.
Our discussion focuses on the salient points for proper interpretation of the 24-2 Swedish Interactive Thresholding Algorithm (SITA) full-threshold Humphrey visual field (HVF) (Carl Zeiss Meditec Inc., Dublin, CA).
24-2: Measures 24 degrees temporally and 30 degrees nasally and tests 54 points. ... or 'Within Normal Limits' (no differences) is only considered when the patient has, or is a suspect for, glaucoma. [20] This is only available in 30-2 and 24-2 analyser protocol. ... The visual field index (VFI) reflects retinal ganglion cell loss and function, ...
Look at the pattern. Look at the GHT, mean deviation, VFI, and pattern standard deviation. Compare to the previous visual fields. The visual field test is among the most important tests to learn to interpret as you begin your career in ophthalmology. Learn about the top 5 most common fields!
10 lut 2024 · Kevin M. Miller, MD, who is in practice in Los Angeles, adds that visual fields are best at identifying progression in moderate to severe glaucoma. “Visual fields are terrible indicators of early disease,” he says.
l field testing can be a difficult skill to master and takes continual practice. When interpreting a standard “Central 24-2 Threshold Test,” the baseline visual field test analyzing the central 24 degrees of vision, the results are divided into 3 sections: patient and test details, displays of sensitivities acro.
15 lut 2013 · Although a standard test program and pattern (e.g., 24-2, Threshold) is often selected for the majority of patients, be sure to confirm that the correct test was selected. • Reliability indices. Examining the reliability indices is the next key step in visual field interpretation ( figure 2 ).
