ABSTRACT

Objective To valuate the effect of high energy ultrapulse CO2 laser on congenital melanocytic nevi of the orbit. Methods 46 patient with congenital melanocytic nevi of eyelid, 58 le-sions were vaporized with high energy ultrapulse CO2 laser. The area of the largest one was 3.0 cm×6.0 cm, and the smallest one was 0.3 cm×0.3 cm, with average of 1.3 cm×2.0 cm. The depth of the vaporizing reached the layer of lowest skin, even the orbicularis, aponeurosis and conjunctiva of tarsus, till no melanin on the wound in view, tried the best to reserve the normal follicle of eyelash.

The overall effect was 94.8 % (55/58). And eyelashes were getting growth. Conclusion The treatment of con-genital melanocytic nevus of eyelid with high energy ultrapulse CO2 is a good method. But to be careful in selecting the lesions that may not he too large.
