ABSTRACT
PURPOSE:
To evaluate the effectiveness of conjunctival cyst ablation using pattern scan laser photoablation.METHODS:
Ninety-four cases of symptomatic conjunctival cysts were included. After staining the surface of a conjunctival cyst with a dark-purple marker pen, an incision was made into the conjunctival cyst using a 26-gauge needle. Low-energy photoablation using 3 × 3 grids of spots was then applied around the incision site for a mean of 50 times. The laser spots were 400 µm in size, the power delivered ranged from 400 to 450 mW, and the duration of each laser pulse was 80 ms.RESULTS:
During a mean follow-up period of 6.5 months (range 6-16 months), 84 cases of conjunctival cysts (89.4%) were successfully corrected by conducting either 1 or 2 laser sessions. The cyst was completely resolved after a single laser session in 74 cases (78.7%). There were 20 cases of recurrence, which involved fixed, thick, and large cysts. The conjunctival cyst recurred again after the second laser session in 2 of the 12 eyes in which the procedure was repeated. The remaining 8 cases were observed without additional treatment. No postoperative complications such as conjunctival scarring or persistent ocular irritation were observed.CONCLUSIONS:
Pattern scan laser photoablation of a conjunctival cyst with the adjunctive use of cyst surface staining to increase the amount of thermal laser energy absorption is a simple and effective method for treating conjunctival cysts in an outpatient clinic.
