• Three patients with erythematotelangiectatic rosacea were examined using infrared photography. The vascular patterns in the malar areas of all the patients were completely obliterated in the photographs. A review of the results of infrared studies on other cutaneous vascular lesions indicates that the disorder in rosacea is not associated with the superficial, collecting veins.
