To evaluate the effectiveness of conjunctival cyst removal using a modified method of argon laser photoablation.
Seventeen cases of symptomatic conjunctival cysts were included. After staining the surface of a conjunctival cyst with a dark purple marker, the cyst was incised using a 26-gauge needle. Low-energy argon laser photoablation was then applied around the incision site for a mean of 100 times.
During a mean follow-up period of 13.3 months (range 6-28 months), all conjunctival cysts were successfully corrected by applying either one or 2 laser sessions. Complete resolution occurred after a single laser session in 14 eyes (82.4%). There were 3 cases of recurrence with medium to large cysts, and repeating the same procedure produced surgical success in all of these cases; the conjunctival cyst recurred again after the second laser session in one of the 3 eyes, but this spontaneously regressed without further treatment. No postoperative complications such as conjunctival scarring or persistent ocular irritation were observed.
Our modified method of argon laser photoablation uses staining of the conjunctival cyst surface to increase the amount of thermal laser energy absorbed by the target. This novel technique is simple and effective for treating conjunctival cysts in an outpatient clinic.
评估使用改良氩激光光凝法切除结膜囊肿的效果。
纳入 17 例有症状的结膜囊肿患者。用深紫色标记物标记结膜囊肿表面后，用 26 号针头切开囊肿。然后在切口周围用低能量氩激光光凝，平均应用 100 次。
平均随访 13.3 个月（6-28 个月），所有结膜囊肿通过应用 1 或 2 次激光治疗均成功矫正。14 只眼（82.4%）单次激光治疗后完全消退。3 例中大型囊肿复发，再次重复相同程序后所有病例均手术成功；其中 1 只眼第二次激光治疗后结膜囊肿再次复发，但未经进一步治疗自行消退。未观察到术后并发症，如结膜瘢痕或持续眼刺激。
我们改良的氩激光光凝法使用结膜囊肿表面染色来增加目标吸收的热激光能量。这种新的技术在门诊治疗结膜囊肿既简单又有效。
