In 41 persons with chronic conjunctivitis, 28 persons with pterygium and 61 eye-healthy persons the Vitamin A and carotene blood level have been examined. All persons with chronic conjunctivitis and pterygium have subjective eye disturbances. In persons with chronic conjunctivitis the vitamin A blood level was lower (men 32 mcg%, women 20 mcg%). In almost all persons with chronic conjunctivitis and pterygium delayed dark adaptation was recorded and the skin-mucosal changes are more frequent.
