Objective: To evaluate the influence of the extent of color-vision deficiency on visual shade-matching ability. Materials and methods: Six groups were investigated: the control group (N = 68), the protan medium deficiency (PMED) group (N = 5), the protan strong deficiency (PSTD) group (N = 5), the deutan mild deficiency (DMID) group (N = 5), the deutan medium deficiency (DMED) group (N = 5) and the deutan strong deficiency (DSTD) group (N = 8). The color vision of the participants was evaluated monocularly using the Hardy-Rand-Rittler (HRR) test and on an HMC Anomaloskop MR (Rayleigh test). The final exam on a Toothguide Training Box consisted of 15 lightness–chroma–hue tasks. The color difference (ΔE* ab) and the shade-matching score (ΣΔE* ab) were computed. The means and the standard deviations for the ΣΔE* ab were calculated. An independent t-test was used for statistical analyses of the data and a comparison of means (α = .05) for protan groups and a one-way analysis of variance (ANOVA) and a post-hoc Bonferroni test (α = .05) for deutan groups. Results: The PSTD group had a mean ΣΔE* ab of 63.38 ± 9.52, which means their selections were significantly worse in comparison to the PMED group (ΣΔE* ab = 47.62 ± 9.88, p = 0.033). The selections of the control group were significantly better in comparison to all groups with color-vision deficiency (control – PMED, p = 0.031; control – PSTD, p < 0.0001; control – DMED, p < 0.0001; control – DSTD, p < 0.0001), except in comparison with DMID group (p = 0.082). The comparisons between deutan groups were not significantly different (DMID – DMED, p = 0.352; DMID – DSTD, p = 0.323; DMED – DSTD, p = 1.000). Conclusion: Participants with strong protan color-vision deficiency are worse at shade matching than participants with medium protan color-vision deficiency. [ABSTRACT FROM AUTHOR] |
| Abstract (Croatian): |
Cilj: Željelo se procijeniti utjecaj stupnja oštećenja kolornoga vida na sposobnost vizualnog određivanja boje. Materijali i metode: Ispitano je šest skupina: kontrolna skupina (N = 68), skupina sa srednjom protanopijom (PMED) (N = 5), skupina s jakom protanopijom (PSTD) (N = 5), skupina s blagom deuteranopijom (DMID) (N = 5), skupina sa srednjom deuteranopijom (DMED) (N = 5) i skupina s jakom deuteranopijom (DSTD) (N = 8). Kolorni vid sudionika ocijenjen je monokularno primjenom Hardy-Rand-Rittlerova testa (HRR) i na HMC anomaloskopu MR (Rayleighev test). Završni test sastojao se od 15 zadataka za određivanja svjetline – zasićenja – nijanse s pomoću Toothguide Training Boxa. Izračunata je razlika u boji (ΔE*ab) i ocjena je podudaranja boja (ΣΔE*ab). Izračunati su prosjeci i standardne devijacije za ΣΔE*ab. Za statističku analizu podataka upotrijebljen je neovisni t-test i usporedba sredina (α = 0,05) za skupine s protanopijom te jednosmjerna analiza varijance (ANOVA) i Bonferronijev post-hoc test (α =,05 ) za skupine s deuteranopijom. Rezultati: Skupina s PSTD-om imala je prosječnu vrijednost za ΣΔE*ab od 63,38 ± 9,52, što znači da su odabiri ispitanika bili značajno lošiji u usporedbi sa skupinom s PMED-om (ΣΔE*ab = 47,62 ± 9,88, p = 0,033). Odabiri u kontrolnoj skupini bili su značajno bolji u usporedbi sa svim skupinama s poremećajem kolornoga vida (kontrola – PMED, p = 0,031; kontrola – PSTD, p <0,0001; kontrola – DMED, p <0,0001; kontrola – DSTD, p < 0,0001), osim u usporedbi sa skupinom s DMID-om (p = 0,082). Usporedbe između skupina s deuteranopijom nisu se značajno razlikovale (DMID – DMED, p = 0,352; DMID – DSTD, p = 0,323; DMED – DSTD, p = 1,000). Zaključak: Sudionici s jakom protanopijom lošije su sparivali uzorke boja u odnosu prema sudionicima sa srednjom protanopijom. [ABSTRACT FROM AUTHOR] |
