Glaucoma, lighting and color vision. An investigation into their interrelationship.
The results of a study on color vision capacity performed with a view to further analyzing glaucomatous dyschromatopsia are reported. The Farnsworth-Munsell 100-hue test was used in a population of 52 subjects (104 eyes) with daylight fluorescent lighting and low-tension halogen lighting. Photocolorimetric observations with each type of lighting were made. It was found that halogen lighting increased the glaucomatous subjects' mean score, the number of dyschromatopsia and the number of blue-yellow dyschromatopsia axes. The authors conclude that halogen lighting is preferable for the Farnsworth-Munsell 100-hue test in glaucoma and confirm the predominance of blue-yellow dyschromatopsia axes in glaucoma.
