To identify preoperative, perioperative and postoperative risk factors that influence the success of pterygium surgery.
This is a prospective study of thirty-six patients with primary or recurrent pterygia. A detailed anamnesis and an ophthalmological examination were performed looking for the following factors: age, race, latitude and altitude of the main place of residence, hours of exposure to the sun, use of protective measures against UV-radiation, classification of pterygium, width of the pterygium at limbus, surgical technique (conjunctival autograft plus suturing versus tissue glue), graft alterations (misapposition, granuloma, haemorrhage, oedema, retraction or necrosis), and postoperative symptoms (foreign-body sensation, pain). The examinations were performed 2 and 7 days and 2, 6 and 12 months after surgery. In addition, recurrence was defined as any growth of conjunctiva into the cornea.
A logistic regression and a survival analysis have been used to perform data analysis. A total number of 36 patients completed a one year follow-up. A total of 13 patients were born and lived in Spain, and 26 came from other countries, mostly Latin America. A total number of 8 males (no women) presented a recurrence, mainly between 2 and 6 months. The hours of sun exposure through their life was independently related to surgical success. Pterygia of less than 5 mm of base width showed a weak positive correlation with recurrence. None of the other factors considered were significantly related to recurrence.
Male gender and high sun exposure are strongly and independently related to surgical success after the removal of pterygia.
确定影响翼状胬肉手术成功的术前、术中和术后危险因素。
这是一项对 36 例原发性或复发性翼状胬肉患者进行的前瞻性研究。详细的病史采集和眼科检查，寻找以下因素：年龄、种族、主要居住地的纬度和海拔、暴露在阳光下的时间、使用防紫外线辐射的保护措施、翼状胬肉的分类、角膜缘处翼状胬肉的宽度、手术技术（结膜自体移植加缝合与组织胶）、移植物改变（错位、肉芽肿、出血、水肿、回缩或坏死）和术后症状（异物感、疼痛）。术后 2 天、7 天和 2 个月、6 个月和 12 个月进行检查。此外，复发定义为结膜任何向角膜生长。
使用逻辑回归和生存分析进行数据分析。共有 36 例患者完成了一年的随访。共有 13 例患者出生并居住在西班牙，26 例患者来自其他国家，主要来自拉丁美洲。共有 8 名男性（无女性）出现复发，主要在 2 至 6 个月之间。一生中暴露在阳光下的时间与手术成功率独立相关。基底宽度小于 5 毫米的翼状胬肉与复发呈弱正相关。其他考虑的因素均与复发无显著相关性。
男性和高阳光暴露与翼状胬肉切除术后手术成功有强烈的独立相关性。
