Color vision in patients with retrobulbar neuritis in multiple sclerosis

Retrobulbar neuritis is often the first and unrecognized clinical sign of multiple sclerosis. The prevalence of disturbances in color vision (activated dyschromatopsia) in patients with retrobulbar neuritis varies from study to study. The assessment of color vision in patients can be carried out throuhg a whole range of diffferent diagnostic methods and tests, which is indispensible for a high-quality workup. Diagnostic methods for examination of color vision include methods of denomination, comparison, discrimination and egalization, while diagnostic tests include dichotomous, qualitative and quantittive tests. During the examination of color vison we use the so-called color equipment, which commmonly includes pseudoisochromatic tables (Ishihara and Stilling), anomaloscopes and panel test. The prevalence of color vision disturabanes in patients with retrobulbar neuritis in multiple sclerosis varies significantly from 15% to 70%, mostly around 50% of cases. Pseudoisochromatic Ishihara tables are most often used for research purposes, which is definitely inadequate for proper diagnosis of color vision disturbances. The diagnosis of active color vision impairment requires the use of more subtle diagnostic methods as well as the use of different and mores sopisticated diagnostic methods and tests from the color equipment available in order to achieve the best possible workup and monitoring of the disease and treatment.
