Colour contrast sensitivity assessment in monozygotic and dyzigotic twins

The purpose of the study. To determine colour perception within pairs of monozygotic (MZ) twins and dizygotic (DZ) twins established by the Farnsworth–Munsell 100 hue (F-M 100). Material and methods. 10 MZ twins and 6 DZ  twins were tested. The computerised F-M program was used for colour discrimination. Results. The results of F-M 100 test in MZ and DZ twins showed 175.45±153.4 vs.91.17 ±57.0, P=0.17; Conclusion. Colour contrast sensitivity assessment was statistical diference worse in MZ than in DZ. Key words: monozygotic twins, dizygotic twins, colour vision, visual acuity.
