Color Vision Defects
Abstract
Photorefractive keratectomy (PRK) has been extensively studied in the literature and its potential application in aircrew has not gone unnoticed. Complication rates following corneal refractive surgery (CRS), including PRK and laser in-situ keratomileusis (LASIK), remain low, with most patients achi...

Human Mutation (31)7 2010
Abstract
We identified three novel mutations in the pore-forming region of CNGA3 (L363P, G367V, and E376K) in patients diagnosed with achromatopsia. We assessed the expression and function of channels with these three new and two previously described mutations (S341P and P372S) in a heterologous HEK293 cell...

Abstract
The customized booth demonstrated illumination meeting CIE standards. The total error scores were overestimated by the classical and moment of inertia methods in all groups for room illumination compared with booth illumination, however overestimation was more significant in the diabetes group....

Abstract
We detected impaired responses using S-cone ERG and blue-on-yellow perimetry OS. We diagnosed this case as acute damage of the blue cone. CONCLUSION: S-cone damage can be determined by electro-physiological and psychophysical examinations in cases of unilateral color abnormality....

Abstract
Purpose. Color-vision deficiency is associated with abnormalities in color matching and color discrimination, but its impact on the ability of people to judge the constancy of surface colors under different lights (color constancy) is less clear. This work had two aims: first, to quantify the degree...

Abstract
We present three patients in whom the initial diagnosis of NTG was eventually revealed to be chiasmal compression secondary to a pituitary tumour. Case 1: a 79-year-old woman was treated for NTG for several months before a bitemporal haemianopia developed and imaging showed a pituitary tumour. Case...

Abstract
The control group had no difficulties in selecting the appropriate beads, while the experimental group had significantly more mistakes, particularly with colors in the blue-violet spectrum. Average scores for the total number correct for the control and experimental groups were 36 (100%) and 27 (74....

Abstract
Genetic analysis of two Pakistani families with retinal disease enabled the establishment of the correct diagnosis of achromatopsia. Two novel mutations were identified in CNGA3 and CNGB3 that are both specifically expressed in cone photoreceptors. Re-evaluation of the clinical status revealed that...

Abstract
Genetic analyses provided direct confirmation of compound heterozygosity. The compound heterozygote showed Schmidt's sign, consistent with an extreme skew in her L : M cone ratio and usually associated with protan carrier status. CONCLUSION: Apart from Schmidt's sign, we found the colour vision of t...

There was no evidence of significant associations between exposure parameters and CCI. This is true for the analyses with all participants as well as for those with the subgroups with high-long versus low-short exposure. Thus, no exposure related changes in the relevant variables were found during t...

Many sunglass tints currently permitted for drivers and riders cause a measurable decrement in the ability of color deficient observers to detect and recognize traffic signals. In general, combinations of signals and sunglasses of similar colors are of particular concern. This is prima facie evidenc...

Abstract
Cone and cone-rod dystrophies can be divided according to the disease course into stationary and progressive disorders or by the genetic mode of inheritance into autosomal-recessive, autosomal-dominant, and X-linked traits. To date, seven genes for autosomal-recessive and nine for autosomal-dominant...

Ocular complications from topical cocaine abuse are rare. Impaired color vision, as in our patient, has been reported in cocaine-withdrawn patients. To our knowledge, this is the first described case of a bilateral and symmetric maculopathy associated with long-term intranasal cocaine use. To avoid...

John Dalton was born in the 18th century and was recognized mainly for his work on the chemical atomic theory and “Dalton's Law” for the partial pressure of gases. However, during his lifetime he was already recognized for his theories on “colorblindness,” with which he was afflicted. He was...

Abstract
The mild clinical phenotype observed is consistent with the residual activity of a severely hypomorphic mutant RPE65. Reduction to <10% of wild-type RPE65 activity by homozygous P25L correlates with almost complete rod function loss and cone amplitude reduction. Functional survival of cones is possi...

Passing the Farnsworth lantern test does not ensure that DCV pilots can distinguish PAPI signal colors. The criterion for passing the lantern test should be made more stringent. In addition the design of PAPI signals can be improved by a better choice of the white color and by providing a redundant...
