Argon laser radiation is used to treat congenital and acquired vascular lesions of the head and neck. Thirteen patients requiring a total of 36 treatments were followed up for a minimum of 1 year to assess the response of the vascular lesion to argon ion radiation. Of the 13 patients, 10 had an excellent result, with the lesion no longer being identifiable. Three of the patients had residual but minimal color remaining in the lesion. There were no complications or hypertrophic scars after 1 year of follow-up. The laser parameters used and the surgical technique followed are outlined.

Colour Contrast

We have assessed the optimal cone contrast sensitivity across eccentricity in human vision of the two cone-opponent mechanisms [L/M or red-green, and S/(L + M) or blue-yellow] and the luminance mechanism. We have used a novel stimulus, termed a ‘sinring’, that is a radially modulated sine-wave arc, Gaussian enveloped in both angular and radial directions. This stimulus overcomes the problem inherent in Gabor stimuli of confounding stimulus spatial frequency, size, and eccentricity and so allows contrast sensitivity to be tracked accurately into the periphery. Our results show that L/M cone opponency declines steeply across the human periphery and becomes behaviourally absent by 25–30 deg (in the nasal field). This result suggests that any L/M cone-opponent neurons found in primate peripheral retina beyond this limit are unlikely to be significant for colour contrast detection measured behaviourally.
