Normal test scores in the Farnsworth-Munsell 100 hue test.
ABSTRACT One hundred and sixty persons aged from 10 to 69 years (106 women, 54 men) with healthy eyes were studied with the Farnsworth-Munsell 100 hue (FM100) test. The mean of the results in the total scores and in the individual box scores in the right and left eye were calculated. The total score was also separately calculated in women and men. The test was administered under the illumination of Macbeth Easel lamp, 1000 lux, and the right eye was tested first. The results were calculated in six different age groups, 10-19 years, 20-29 years, etc. The mean of the total scores in the right eye varied from 7.44+/-2.46 (SD) to 10.07+/-2.03 in different age groups and in the left eye from 7.56+/-2.36 to 10.16+/-2.68. The scores changed significantly with the age: the correlation between the age and the test scores by linear regression gave significant results, in the right eye (R = 0.308, P = 0.0001), and in the left eye (R = 0.246, P = 0.0021). The present study with the normal error scores in the FM100 test and its individual boxes in persons aged 10-69 years gives clinicians working with colour vision defects a possibility to estimate the normality or abnormality of the results in their patients.

ABSTRACT: The purpose of the study was to determine whether the use of a GABAergic antiepileptic drug (AED), tiagabine, affects color vision and contrast sensitivity. Twenty newly diagnosed patients with partial epilepsy (aged 19-72 years), receiving tiagabine as their initial monotherapy for 5-41 months were examined. Color vision was examined with the Standard Pseudoisochromatic Plates 2 (SPP2), with the Farnsworth-Munsell 100 Hue Test (FM100) and with the Color Vision Meter 712 (CVM) anomaloscope. Contrast sensitivity was measured with the Pelli-Robson letter chart. Three patients excluded from the color vision evaluation for congenital red-green color vision defects. Seven out of 17 patients (41%) had acquired color vision deficit examined with the FM100. The CVM anomaloscope revealed minor defects in two patients. Contrast sensitivity function was within normal ranges. The present study suggests that AED therapy with tiagabine, like with other established and newer AEDs may interfere with color perception.Epilepsy Research 01/2006; 67(3):101-7. · 2.24 Impact Factor

ABSTRACT: The eye and visual system are valuable in many areas of translational research such as stem cell therapy, transplantation research and gene therapy. Changes in many ocular tissues can be measured directly, easily and objectively in vivo (e.g. lens transparency; retinal blood vessel calibre; corneal endothelial cell counts) and so the eye may also be a uniquely useful site as a model of ageing. This review details cellular, molecular and epigenetic mechanisms related to ageing within the eye, and describes ocular parameters that can be directly measured clinically and which might be of value in ageing research as the translational "window to the rest of the body". The eye is likely to provide a valuable model for validating biomarkers of ageing at molecular, epigenetic, cellular and clinical levels. A research agenda to definitively establish the relationship between biomarkers of ageing and ocular parameters is proposed.Ageing research reviews 12/2012; · 5.62 Impact Factor
