In the reliability study of Good et al (2005; 1.12 § 0.12 for the Wrst and 1.10 § 0.12 for the second examination) lower CCI values were shown.…”

“…This underlines the critical remarks on the precision of the measurements which were cited above. In Table 4 an increase of explained CCI variances can be observed from the Wrst (12-16%) to the second (19-26%) measurement, which also suggests the necessity for a discussion of the reliability of this method (Good et al 2005). However, with higher portions of explained variance the exposure-related variances did not change markedly.…”

“…The colour confusion index is 1.0, if the arrangement of the caps is correct and increases with the number and the degree of permutations. The test was administered twice per examination for the right eye to increase the reliability of the measurements (Good et al 2005). In the statistical evaluations the measure CCI was used.…”

Both acute styrene exposure levels of 40 ppm (range of standard deviation up to 54 ppm) and long term exposures to 27 ppm (range of standard deviation up to 44 ppm with higher exposure levels in the past) for a period of about 15 years were not identified as causing elevated risks for the investigated parameters of colour vision and contrast sensitivity. This statement contradicts the published results for styrene-related colour vision deficiencies but it seems to be compatible with published results for contrast sensitivity due to styrene exposure.

“…Each eligible eye was tested and the child was asked to place the 15 colored caps in order. The Lanthony desaturated test was always performed twice to check for repeatability [17]. The color vision tests were performed under daylight conditions obtained by a D65 (illuminant D) light source at 270 lux.…”

Cone function in children with a history of preterm birth

Color vision was examined by psychophysical tests and photopic color full-field electroretinography (ERG) in formerly preterm children, and compared with those of full-term children. In a prospective case-control study, 25 patients with a history of preterm birth 7-14 years of age were divided into three groups: group I, laser-treated retinopathy of prematurity [ROP] (n = 7); group II, spontaneously regressed ROP (n = 8); group III, no ROP (n = 10). Age-matched full-term born children comprised the control group (n = 8). Color vision was assessed by Fansworth D15 and Lanthony desaturated D15 tests. The cone function was tested using photopic full-field ERG. Besides the ISCEV standard stimuli, blue light on amber background was also used (S-cone ERG). The correlation between ERG parameters and prematurity or ROP was determined. We found no significant differences between any patient group and the control group in the results of the psychophysical tests, and implicit times of the ERG responses. The ERG b-wave amplitudes were significantly lower in group I (laser-treated ROP) compared to controls, for 2 of 4 stimulus conditions i.e. the standard (P = 0.028) and S-cone (P = 0.017) single flash ERGs. The general estimating equation model statistics found a significant effect of prematurity on the b-wave amplitudes (P = 0.025, standard, P = 0.014, S-cone ERG). A slightly reduced photopic ERG b-wave amplitude may be associated with prematurity.

“…Although some previous reports have proven that this quantitative scoring system using the D-15DS was useful for screening 8 and correlated with the score of the 100-hue test, 12,13 the reference intervals were investigated with only a small sample size 3,14,15 and adequate discrimination values are still unclear. In general, the 90th or 95th percentile value in a normal population is important for colour vision testing.…”

Purpose To better understand the reference values and adequate discrimination values of colour vision function with described quantitative systems for the Lanthony desaturated D-15 panel (D-15DS). Methods A total of 1042 Japanese male officials were interviewed and underwent testing using Ishihara pseudoisochromatic plates, standard pseudoisochromatic plates part 2, and the D-15DS. The FarnsworthMunsell (F-M) 100-hue test and the criteria of Verriest et al were used as definitive tests. Outcomes of the D-15DS were calculated using Bowman's Colour Confusion Index (CCI). The study design included two criteria. In criterion A, subjects with current or past ocular disease and a best-corrected visual acuity less than 0.7 on a decimal visual acuity chart were excluded. In criterion B, among subjects who satisfied criterion A, those who had a congenital colour sense anomaly were excluded. Results Overall, the 90th percentile (95th percentile) CCI values for criteria A and B in the worse eye were 1.70 (1.95) and 1.59 (1.73), respectively. In subjects satisfying criterion B, the area under the receiver operating characteristic curve was 0.951 (95% confidence interval, 0.931-0.971). The CCI discrimination values of 1.52 or 1.63 showed 90.3% sensitivity and 90% specificity, or 71.5% sensitivity and 95% specificity, respectively, for discriminating acquired colour vision impairment (ACVI). ConclusionWe provided the 90th and 95th percentiles in a young to middle-aged healthy population. The CCI is in good agreement with the diagnosis of ACVI. Our results could be helpful for using D-15DS for screening purposes.
