To determine the efficacy and safety of argon laser photocoagulation of pinguecula by evaluating 1-year outcomes.
Twenty-one eyes of 15 patients treated with argon laser photocoagulation (photocoagulation group) and 23 eyes of 16 patients treated with surgical excision (excision group) were retrospectively reviewed. Cosmetic outcome was evaluated by patient's self-report on a 5-grade scale (excellent, good, acceptable, poor, and very poor), and evaluation of treatment outcome was based on objective findings of anterior segment photography and anterior segment optical coherence tomography.
Overall cosmetic results were excellent or good in 90.5% of laser-treated cases and 78.6% of surgically treated cases. There was no significant difference in cosmetic outcome (P = 0.15). Nineteen (90.5%) and 17 (63.9%) cases demonstrated complete removal of pingueculae after laser photocoagulation and surgical excision, respectively. The anatomic outcome was not significantly different between the 2 groups (P = 0.25). Subconjunctival hemorrhage and conjunctival scarring with an irregular surface occurred less frequently in the photocoagulation group than in the excision group [34.8% vs. 0% (P = 0.003) and 30.4% vs. 4.8% (P = 0.048), respectively].
Argon laser photocoagulation is an effective and safe method for removing a pinguecula for cosmetic purposes. The method facilitates control of the extent and depth of removal and thus minimizes conjunctival defects and other complications.
通过评估 1 年的结果，确定氩激光光凝治疗翼状胬肉的疗效和安全性。
回顾性分析 15 例 21 眼接受氩激光光凝（光凝组）和 16 例 23 眼接受手术切除（切除组）的患者。通过患者的 5 级自我报告评估美容效果（优秀、良好、可接受、差和非常差），并通过眼前段摄影和眼前段光学相干断层扫描的客观发现评估治疗效果。
激光治疗组和手术治疗组的整体美容效果分别为 90.5%和 78.6%为优秀或良好。美容效果无显著差异（P=0.15）。19 例（90.5%）和 17 例（63.9%）激光光凝和手术切除后翼状胬肉完全切除。两组解剖结果无显著差异（P=0.25）。光凝组结膜下出血和结膜瘢痕发生率低于切除组[34.8%比 0%（P=0.003）和 30.4%比 4.8%（P=0.048）]。
氩激光光凝是一种有效且安全的治疗翼状胬肉的方法，可用于美容目的。该方法有助于控制切除的范围和深度，从而最大限度地减少结膜缺损和其他并发症。
