Nomograms for the assessment of Farnsworth-Munsell 100-hue test scores.

Although the Farnsworth-Munsell 100-hue test is a sensitive means of evaluating congenital and acquired color vision deficiencies, using the data it provides involves complex calculations. We have developed two nomograms that permit the clinician to determine quickly and easily whether a given score is normal for the patient's age and whether the difference between fellow eyes is within the normal range.
