Chemical cautery

Verrucae are self-limiting but can be very serious in the immunosuppressed. Treatment is primarily cosmetic but also prevents further dissemination. Most verrucae lesions resolve spontaneously after several months to years therefore therapy should be conservative. Because the lesions are localized to the epidermis, most treatments are limited to this level and should not result in scarring. Benign treatments include topical applications of irritants salicylic acid and lactic acid, applied under an occlusive barrier, can be purchased over the counter. More advanced treatment modalities include cryotherapy, surgical removal, or electro-or chemical cautery. Neither of these cautery methods is suitable for lesions on the lid margin because of the risk to the ocular surfece. 

There are a number of surgical techniques and procedures used to treat eyelid and periocular lesions and anomalies. These techniques include chemical and thermal cautery, used to destroy tissue incision, used to cut into and/or separate tissue and excision, used to remove tissue.
