Code	Display	Definition
111825	Visual Field TOP Test Strategy	Tendency Oriented Perimetry. Fast thresholding algorithm. Test strategy makes use of the interaction between neighboring test locations to reduce the test time compared to normal full threshold strategy by 60-80%.In: Morales J, Weitzman ML, Gonzalez de la Rosa M. Comparison between Tendency-Oriented Perimetry (TOP) and octopus threshold perimetry. Ophthalmology, 2000, 107: 134-142.
111836	Visual Field CLIP Test Strategy	Continuous Luminance Incremental Perimetry, which measures at first the individual reaction time of the patient and threshold values in every quadrant. The starting value for the main test is slightly below in individual threshold.
111815	Visual Field SITA-Standard Test Strategy	Swedish Interactive Thresholding Algorithm (SITA). Strategy gains testing efficiency through use of visual field and information theory models.In: Bengtsson B, Olsson J, Heijl A, Rootzen H. A new generation of algorithms for computerized threshold perimetry, SITA. Acta Ophthalmologica Scandinavica, 1997, 75: 368-375.
111826	Visual Field Dynamic Test Strategy	Dynamic strategy is a fast thresholding strategy reducing test duration by adapting the dB step sizes according to the frequency-of-seeing curve of the threshold. Reduction of test time compared to normal full threshold strategy 30-50%.
111837	Visual Field CLASS Strategy	A supra threshold screening strategy. The starting stimuli intensities depend on the classification of the patient's visual hill by measuring the central (fovea) or peripheral (15° meridian) threshold. The result of each dot slightly underestimates the sensitivity value (within 5 dB).
111816	Visual Field SITA-SWAP Test Strategy	Adaptation of SITA testing methods to Blue-Yellow testing.
111827	Visual Field Normal Test Strategy	Traditional full threshold staircase strategy. Initial intensities are presented, based on anchor point sensitivities in each quadrant and based on already known neighboring sensitivities. In a first run, thresholds are changed in 4dB steps until the first response reversal. Then the threshold is changed in 2 dB steps until the second response reversal. The threshold is calculated as the average between the last seen and last not-seen stimulus, supposed to correspond with the 50% point in the frequency-of-seeing curve.
111817	Visual Field SITA-Fast Test Strategy	Similar to SITA-Standard but with less strict criteria for closing test points. Intended for patients who must be tested in the shortest possible time.In: Bengtsson B, Hejl A. SITA Fast, a new rapid perimetric threshold test. Description of methods and evaluation in patients with manifest and suspect glaucoma. Acta Ophthalmologica Scandinavica, 1998, 76: 431-437.
111828	Visual Field 1-LT Test Strategy	One level screening test: Each test location is tested with a single intensity. The result is shown as seen or not-seen. The intensity can either be a 0 dB stimulus or a predefined intensity.
111818	Visual Field Full Threshold Test Strategy	Threshold test algorithm that determines a patient's sensitivity at each test point in the threshold test pattern by adjusting intensity by 4 dB steps until the patient changes their response, and then adjusts the intensity in the opposite direction by 2 dB steps until the patient changes their response again. The last stimulus seen by the patient is recognized as the threshold for that point.The starting values are determined by first thresholding a "primary" point in each quadrant then using the results of each primary point to determine the starting values for neighboring points.
111829	Visual Field 2-LT Test Strategy	Two level screening test: Each test location is initially tested 6 dB brighter than the age corrected normal value.
111819	Visual Field FastPac Test Strategy	Similar to the Full Threshold algorithm except that it steps by 3 dB and only crosses the threshold only once.In: Flanagan JG, Wild JM, Trope GE. Evaluation of FASTPAC, a new strategy for threshold estimation with the Humphrey Field Analyzer, in a glaucomatous population. Ophthalmology, 1993, 100: 949-954.
111830	Visual Field LVS Test Strategy	Low Vision Strategy is a full threshold normal strategy with the exception that it starts at 0 dB intensity and applies stimulus area V.
111820	Visual Field Full From Prior Test Strategy	Identical to Full Threshold except that starting values are determined by the results of a previous test performed using the same test pattern and the Full Threshold test strategy.
111831	Visual Field GATE Test Strategy	German Adaptive Threshold Estimation is a fast strategy based on a modified 4-2 staircase algorithm, using prior visual fields to calculate the starting intensity. In: Chiefer U, Pascual JP, Edmunds B, Feudner E, Hoffmann EM, Johnson CA, Lagreze WA, Pfeiffer N, Sample PA, Staubach F, Weleber RG, Vonthein R, Krapp E, Paetzold J. Comparison of the new perimetric GATE strategy with conventional full-threshold and SITA standard strategies. Investigative Ophthalmology and Visual Science, 2009, 51: 488-494.
111821	Visual Field Optima Test Strategy	Similar to FastPac except that the steps are pseudo-dynamic (differ based on the intensity of the last presentation).
111832	Visual Field GATEi Test Strategy	Similar to GATE. The i stands for initial. If there was no prior visual field test to calculate the starting values, an anchor point method is used to define the local start values.
111822	Visual Field Two-Zone Test Strategy	Suprathreshold testing strategy, in which each point is initially tested using stimulus that is 6 dB brighter than the expected hill of vision. If the patient does not respond, the stimulus is presented a second time at the same brightness. If the patient sees either presentation, the point is marked as "seen"; otherwise it is marked as "not seen".
111833	Visual Field 2LT-Dynamic Test Strategy	A test started as two level screening test. In the course of the test, the threshold of relative defects and/or normal test locations has been quantified using the dynamic threshold strategy.
111823	Visual Field Three-Zone Test Strategy	An extension of the two-zone strategy in which test points where the second stimulus is not seen are presented with a third stimulus at maximum brightness.
111834	Visual Field 2LT-Normal Test Strategy	A test started as two level screening test. In the course of the test, the threshold of relative defects and/or normal test locations has been quantified using the normal full threshold strategy.
111824	Visual Field Quantify-Defects Test Strategy	An extension of the two-zone strategy, in which test points where the second stimulus is not seen receive threshold testing to quantify the depth of any detected scotomas.
111835	Visual Field Fast Threshold Test Strategy	Takes neighborhood test point results into account and offers stimuli with an adapted value to save time.
