Efficacy of Argon Laser Photoablation for Conjunctival Cysts

This paper aims to study the efficacy and safety of argon laser photoablation for conjunctival cysts.

A retrospective chart was reviewed in 23 eyes of 23 patients receiving argon laser photoablation to treat conjunctival cysts at Quzhou People’s Hospital from December 2020 to February 2023. Results of success rate, subconjunctival hemorrhage, conjunctival scarring and ocular irritation were recorded for analysis.

All patients were followed up for 12 months. Complete resolution occurred after a single laser session in 19 eyes (82.6%). Two cases succeeded after the second laser treatment (the final success rate was 91.3%). One case recurred again after the second laser session, but it was smaller than before, and he refused treatment again. One case stopped laser photoablation for massive subconjunctival hemorrhage during treatment, and she chose surgical excision later on. No conjunctival granuloma was observed after argon laser photoablation. Ocular irritation usually disappears within one week.

Argon laser photoablation is a safe and effective treatment for conjunctival cysts in an outpatient clinic, especially for small fixed cysts.
