— The Farnsworth‐Munsell 100‐Hue test is frequently used to assess acquired colour vision defects. In diabetic retinopathy the acquired defect is a mild or severe type III (Tritan) defect which may be coupled with poor overall hue discrimination. In consequence, error scores are often high and the 100‐Hue polar diagram is difficult to interpret. In this study the averaging method of analysis proposed by Dain and Birch is used to examine 120 100‐Hue plots obtained by patients with proliferative diabetic retinopathy. These plots have either moderate (150–300) or high error scores (>300). The method of analysis is found to be effective in determining whether a Tritan defect is present or not.
