You look at a dot in the middle of the grid and describe any areas that may appear wavy, blurry or blank. Trend-based progression will determine the rate of progression. If a patient experiences non-glaucomatous loss due to vascular occlusion, ischemic optic neuropathy or panretinal laser, it is necessary to establish a new baseline for visual field testing as well as change the tests used in progression analysis. CPT Assistant indicates "Code 92081 is designated as a unilateral or bilateral procedure.

Gaze tracking measures up to one degree, whereas traditional fixation monitoring is sensitive for three degrees (half the size of the physiologic blind spot). Know if a test is reliable; fixation losses greater than 20% can indicate poor reliability, but improper mapping of the blind spot can cause false elevation of this index. Points straddle the mid-line, allowing for better identification of glaucomatous defects. For instance, if testing was performed at age 59 and, on subsequent examinations, age 60, the second test would be compared with a different database than the first test.

Keep in mind that detecting progression often takes two or more years. False Negatives This is when the patientat first responds to a dim light, but later in the test does not respond to a brighter light in that same location. However, we often see patients who demonstrate significant RNFL loss prior to repeated visual field defects as well as patients progressing on their fields without detectable progression of RNFL or ganglion cell loss. Swedish Interactive Thresholding Algorithm (SITA) Standard in 24-2 pattern with stimulus size III is generally the preferable test for most routine glaucoma and neurological testing.4 Clinicians often have the misconception that SITA Fast strategy is an easier test for patients who have difficulty taking a SITA Standard or full threshold strategy test.
