Personalized Simulations of Colour Vision Deficiency

Colour vision deficiency (CVD) affects the everyday lives of a large number of people, but it is difficult for others – even friends and family members – to understand the experience of having CVD. Simulation tools can help provide this experience; however, current simulations are based on general models that have several limitations, and therefore cannot accurately reflect the perceptual capab...

Colour vision in vitamin A deficiency

suggests, as do our data, that responses to 1-x-OHD, and I-ax, 25-(OH)2D, are different enough to have important implications in treatment. Although hypercalcaemia remains a serious risk with all vitamin D derivatives the rapid reversal that is possible after I-x, 25-(OH),D, treatment makes this agent preferable to calciferol and possibly to 1-x-OHD,. This is particularly so in patients in whom...

Acquired colour vision deficiency in patients receiving digoxin maintenance therapy.

BACKGROUND/AIMS Disturbances of colour vision are a frequently reported sign of digoxin toxicity. The aim of this study was to investigate the incidence of acquired colour vision deficiency in elderly hospitalised patients receiving maintenance digoxin therapy. METHODS 30 patients (mean age 81.3 (SD 6.1) years) receiving digoxin were tested using a battery of colour vision tests (Ishihara, AO...
