BACKGROUND We sought to investigate the association between blood pressure levels and prevalence of acquired color vision impairment in middle-aged Japanese men. METHODS Participants underwent color vision testing, ophthalmological examination, standardized interview, physical record examination, and venous blood examination. Cardiovascular disease risk factors were determined based on blood ...

m In the detection of color vision deficiencies, the focus is not only on the disturbed color axis, but also on the degree of disturbed color vision. Therefore, in order to find out the normal sum of errors, we evaluated this color test in a normal population. Methods: 95 subjects (m:f=71:24) without any ocular or general chronic disease were tested monocularly with tie desaturated Roth 26 HUE ...

Abstract Soil color has historically been estimated visually, but inaccuracies with this method have documented, including disagreement in evaluators, blindness, and differences physical books due to weathering. As new technologies become available soil scientists, a reliable digital determine the field could offer solution these inaccuracies. This research aimed assess if visual estimates of m...

Performance of recently proposed multispectral imaging system for fast acquisition of two dimensional distribution of reflectance spectrum is experimentally studied. The system operation is based on a subspace vector model in which any reflectance spectrum is described in the compressed form as a linear combination of few spectral functions. A key element of the proposed system is a light sourc...

Clinical color-vision tests are evaluated within the framework of a model of chromatic discrimination in terms of cone excitation. The motivation for this study was to derive a method for evaluation of test design, test sensitivity, and observer performance. The discrimination model is based on the assumption that chromatic discrimination is mediated in two independent channels, one for short-w...

AIM To evaluate the effects of chronic smoking on color vision in young subjects. METHODS This study included 91 smokers and 88 non-smokers (a total of 179 volunteers) without any ophthalmologic and systemical disorders. The subjects were between 18-40 years of age with a best corrected visual acuity (BCVA) of 20/20, normal anterior and posterior segment examinations and normal intraocular pr...

OBJECTIVE The aims of our study were to evaluate whether deficits in color vision exist in epileptic adolescents, to study if monotherapy with valproic acid (VPA) and carbamazepine (CBZ) can affect color vision, and to determine the possible relationship between abnormal color vision tests and AEDs dosage and their serum concentrations. PATIENTS We examined 45 epileptic patients before the be...
