“…Clinically, contrast sensitivity becomes relevant for several eye diseases such as cataract [6][7][8], glaucoma [9,10], amblyopia [11,12], multiple sclerosis [13][14][15], macular degenerations [16,17], and diabetic retinopathy [18,19]. The knowledge of the smallest perceivable contrast is also essential in order to verify the success of ocular surgeries e.g.…”

Since contrast sensitivity (CS) relies on the accuracy of stimulus presentation, the reliability of the psychophysical procedure and observer's attention, the measurement of the CS-function is critical and therefore, a useful threshold contrast measurement was developed. The Tuebingen Contrast Sensitivity Test (TueCST) includes an adaptive staircase procedure and a 16-bit gray-level resolution. In order to validate the CS measurements with the TueCST, measurements were compared with existing tests by inter-test repeatability, testretest reliability and time. The novel design enables an accurate presentation of the spatial frequency and higher precision, inter-test repeatability and test-retest reliability compared to other existing tests. 429-441 (1946). 4.

“…Arden & Jacobson (1978) used black and white gratings in glaucoma screening and demonstrated losses at low spatial frequencies in patients with glaucoma and ocular hypertension. The incidence of false-positive and false-negative results was too high, however, even after improvement of the technique by others (Atkin et al 1979;Lundh 1985a). Measuring contrast sensitivity peripherally seemed to improve accuracy, but was tiI..4e-eonsuming (Lundh 1985b;FalcaoReis et al 1990).…”

ABSTRACT.Purpose: To evaluate a new test for peripheral colour contrast sensitivity as a tool for early diagnosis of glaucoma.Patients andMethodc Peripheral colour contrast sensitivity was measured by a computer and colour monitor system developed by Arden and co-workers. The monitor displays an annulus subtending 25" at the retina. During the test, 45" of the annulus is removed in one of four quadrants. The patient is asked to identify this quadrant, first at suprathreshold levels and then as the colour contrast between the annulus and the background is vaned in order to establish the threshold for identification. The tested colours were varied along the protan, deutan and tritan colour confusion axes, respectively. Thirty-three normal subjects, 22 glaucoma patients and 69 ocular hypertensive patients were examined. The ocular hypertensive patients were divided into a low risk group, a medium risk group and a high risk group. Results: The colour contrast thresholds for the glaucoma group and the high risk ocular hypertensive group were significantly (p < 0.001) higher for all three colour axes compared with the normal group. There were also significant (p < 0.05-0.001) differences for all axes between the glaucoma group on the one hand and the ocular hypertensive low risk group on the other hand. There were, however, overlaps in colour contrast thresholds between all groups. Conclusion: Although there is a large and statistically significant difference in average colour contrast thresholds between normals and glaucoma patients, it was difficult to find an appropriate cut-off point to separate the two groups. Further studies must clarify the influence of early stages of common diseases such as cataract, diabetes and age-related maculopathy on colour contrast sensitivity.
