To determine the prevalence of various causes of tearing among patients referred to an oculoplastic clinic.
A prospective study on all patients seen in an oculoplastic clinic with a chief complaint of tearing. The cause of tearing was determined on the basis of the anatomical location of the primary etiology.
This study included 357 patients with a mean age 53.9 years. Punctal stenosis was the most common etiology, affecting 37.8% of the patients. Among patients with punctual stenosis, 63.4% were women over 50-year-old (P = 0.001); 55.6% had tearing for less than 6 months (P = 0.038), and all of them had associated chronic blepharitis. The remaining study participants had dry eye with reflex tearing (27.7%), nasolacrimal duct obstruction (10.1%), canalicular obstruction (4.2%), entropion or ectropion (3.4%), pterygium (1.7%), megalo-caruncle (1.7%), and functional tearing (1.7%).
The outcomes of this study indicate the most common cause of tearing is punctal pathology. Therefore, slit lamp evaluation with careful attention to the punctum is warranted in all patients with tearing.
确定转诊至眼整形门诊的患者中各种流泪原因的患病率。
对所有因流泪为主诉前来眼整形门诊就诊的患者进行前瞻性研究。根据主要病因的解剖位置确定流泪原因。
本研究纳入357例患者，平均年龄53.9岁。泪点狭窄是最常见的病因，影响37.8%的患者。在泪点狭窄患者中，63.4%为50岁以上女性（P = 0.001）；55.6%的患者流泪时间少于6个月（P = 0.038），且所有患者均伴有慢性睑缘炎。其余研究参与者有干眼伴反射性流泪（27.7%）、鼻泪管阻塞（10.1%）、泪小管阻塞（4.2%）、睑内翻或睑外翻（3.4%）、翼状胬肉（1.7%）、巨大泪阜（1.7%）和功能性流泪（1.7%）。
本研究结果表明，流泪最常见的原因是泪点病变。因此，对于所有流泪患者，进行裂隙灯检查并仔细观察泪点是必要的。
