PURPOSE Leber's hereditary optic neuropathy (LHON) is a maternally inherited disease resulting in loss of central vision and dyschromatopsia, caused by mitochondrial DNA point mutations. However, only a subset of the mutation carriers becomes affected, with a higher penetrance in males. This study was conducted to investigate chromatic losses in asymptomatic carriers of the LHON mutation. MET...
The HRR pseudoisochromatic plate (pip) test was originally designed as a screening and diagnostic test for color vision deficiencies. The original HRR test is now long out of print. We evaluate here the new 4th edition of the HRR test, produced in 2002 by Richmond Products. The 2002 edition was compared to the original 1955 edition for a group of subjects with normal color vision and a group wh...
Two families are described in which the Ehlers-Danlos syndrome is apparently transmitted as an X-linked recessive character. The results of tests for the Xg blood groups and for colour vision show that the locus for the Ehlers-Danlos syndrome is not close to that for the Xg groups nor very close to the locus for deutan colour-blindness.The clinical features of this variety of the Ehlers-Danlos ...
et. al, 1968/1969) and give an estimate of 0-23 for the recombination fraction with 9500 confidence limits of 0-13 to 0 43. These results confirm the linkage relationships between deutan colour blindness and Becker muscular dystrophy but since the loci for Duchenne muscular dystrophy and colour blindness are not within measurable distance of each other these results indicate that the Becker and...
In the past, equine color vision was tested with stimuli composed either of painted cards or photographic slides or through physiological testing using electroretinogram flicker photometry. Some studies produced similar results, but others did not, demonstrating that there was not yet a definitive answer regarding color vision in horses (Equus caballus). In this study, a pseudoisochromatic plat...
