Argon laser photoablation may treat superficial conjunctival nevus
Argon laser photoablation may be used to treat superficial conjunctival nevus instead of surgical excision, according to a study.
The 3-year retrospective, interventional case series analyzed records of 263 eyes of 230 patients who had undergone argon laser photoablation. The average argon laser spot size was 200 µm with a duration of 0.1 second and power of 321.5 ± 9.23 mW.
One session was required for complete nevus removal in 212 eyes (81%), two sessions were required for complete removal in 46 eyes (17%), and three sessions were required for complete removal in five eyes (2%). Complete removal of the conjunctival nevus occurred in all patients after it was rubbed with a cotton-tipped swab immediately after photoablation.
No significant complications were reported. One patient experienced recurrence 1 year after photoablation, which was attributed to overexposure to ultraviolet radiation.
