目的：分析先天性泪腺皮肤瘘伴异位泪腺的临床表现，总结其治疗方案。方法：采用病例研究与文献回顾方法，记录1例确诊为先天性泪腺皮肤瘘伴异位泪腺患儿的外观照片、泪道探查冲洗情况、泪腺瘘管数字减影检查、泪腺瘘管CT造影检查等结果。予患者行泪腺瘘管下段及异位泪腺切除+泪腺瘘管上段转位结膜囊吻合代泪腺导管术，术中切除的病变组织行病理检查，术后随访。以“泪腺瘘”、“异位泪腺”为检索词，在 PubMed、CNKI 数据库中进行文献检索，检索到相关文献共 25 篇。结果：患儿为男性，5岁，眼科检查于左眼上睑中外1/3处见直径约1 mm瘘口，瘘口皮肤凹陷并有簇状毛发生长，有透明液体从瘘口阵发性流出。泪器检查示左上睑皮肤瘘管开口朝外上方，瘘管探查从瘘口进针，瘘管先是内下方走行再向外下走行，在距皮面3.5 mm处有一软性抵抗，加压不能突破，冲洗液原路反流，无脓液或血性液体反流。左眼泪腺瘘管数字减影检查示左眼泪腺瘘管造影剂存留，瘘管深部存在扇形腔隙。泪腺瘘管CT造影结果显示左眼外侧泪腺高密度影。术后随访6个月，患儿左眼上睑切口愈合好，未见瘘管复发，转位的泪腺瘘管成功将泪液引流入上穹隆结膜囊内。结论：先天性泪腺瘘同时合并先天性泪腺异位和毛发异位者临床上罕见，术前详细检查和精确诊断对指导治疗很有帮助；在明确主泪腺是正常的情况下，完整切除异位的泪腺组织，并行泪腺瘘管转位吻合于上穹隆结膜囊代泪腺导管术，是一种较好的治疗选择。

Objective: To demonstrate the clinical characteristics and surgical effects of congenital lacrimal gland cutaneous fistula with ectopic lacrimal gland. Methods: Observational case study and literature review. The results of appearance photographs, lacrimal duct probing and irrigation, digital subtraction imaging of the lacrimal fistula, and CT scanning of lacrimal fistula in a patient diagnosed with lacrimal gland cutaneous fistula with ectopic lacrimal gland were recorded. The surgical treatment for the patient was explored. The surgical strategy entailed resecting the lower segment of the lacrimal gland fistula and ectopic lacrimal gland, combined with transposing the upper segment of lacrimal gland fistula for conjunctival sac anastomosis, instead of using lacrimal gland catheter. Pathological examination and postoperative follow-up were conducted. Results: Ophthalmic examination revealed a fistula with a diameter of approximatedly 1 mm in medial-temporal 1/3 of the upper eyelid of the left eye. The skin surrounding the fistula was sunken and covered with tufts of hair. There was a paroxysmal discharge of clear fluid from the fistula. Lacrimal examination showed that the opening of the fistula on the skin of the left upper eyelid was directed outward and upward. Fistula exploration was conducted through the opening. The fistula tract initially coursed medially and caudally, then laterally and caudally. At a depth of 3.5mm from the dermal surface, a soft resistance was encountered that could not be overcome with forced pressure. The irrigation fluid refluxed along its original pathway, with no pus or bloody fluid regurgination. Digital subtraction imaging of the lacrimal fistula in the left eye demonstrated that contrast media remained and formed fanshaped spaces in the depth of the fistula. CT results of lacrimal fistula revealed a high density of lacrimal gland in left eye. During outpatient follow-up six months after surgery, the incision on the left upper eyelid was observed to have healed well, with no recurrence of the fistula The transposed lacrimal fistula successfully diverted tears into the conjunctival sac of the upper fornix. Conclusions: Congenital lacrimal gland cutaneous fistula combined with congenital ectopic lacrimal gland and ectopic hair is rare in clinical practice. Detailed preoperative examination and accurate diagnosis are extremely beneficial for guiding treatment. When the main lacrimal gland is normal, a better treatment choice involves completely removing the ectopic lacrimal gland tissue and transferring the lacrimal gland fistula to the conjunctival sac of the upper fornix to replace the lacrimal gland catheter.

前段巨眼(anterior megalophthalmos, AM)是一种罕见的双侧非进展性先天性眼前段扩大疾病，表现为大角膜、角膜厚度正常或轻中度变薄、前房明显加深、睫状环扩大和悬韧带松弛。早期症状可仅表现为角膜散光和屈光不正等，并发性白内障和晶状体脱位是AM患者视力下降的主要原因。眼前段解剖结构的异常使AM患者的白内障手术具有很大的挑战性。首先，极端前房深度引起的有效晶状体位置(ELP)预测误差及公式选择不当是导致其术后较大屈光误差的主要原因；其次，悬韧带松弛易导致晶状体脱位、后囊膜破裂和玻璃体脱出等术中并发症的发生；由于超大囊袋及悬韧带松弛，人工晶状体(IOL)偏心甚至脱位也是术后常见的并发症。因此，需根据患者悬韧带情况、晶状体混浊程度采取合适的手术方式及谨慎选择IOL的类型。采用手法小切口晶状体囊外摘除术，可避免超声乳化的高灌注压对悬韧带的进一步损伤，增加手术的安全性；植入光学面及襻宽大的IOL术后具有较好的稳定性；新公式如Barrett Universal Ⅱ、Kane和EVO等公式具有较好的屈光预测准确性。然而，目前关于AM患者的白内障手术治疗报道仍属于个案报道，未来还需要更大样本量的临床研究进一步证实。

脉络膜破裂大部分是由撞击引起的对冲伤，冲击力通过玻璃体传导眼底引起，因此一般脉络膜破裂会有比较明确的外伤或者钝挫伤病史。本文将报告1例16岁体校男生在无明显外伤史出现多发性脉络膜破裂伤，通过查阅文献发现有文献报道在隐匿性假性黄色瘤(pseudoxanthoma elasticum，PXE)疾病中可在无明显外伤或轻微外伤出现脉络膜破裂，并根据文献复习考虑本病例为隐匿性PXE可能。

Most of the choroidal rupture is mostly caused by impact injury, and the impact force is caused by the vitreous conduction through the fundus. Therefore, the choroidal rupture generally has a clear history of trauma or blunt trauma. This article will report a case of a 16-year-old boy in a sports school who developed multiple choroidal ruptures without obvious trauma history. Through literature review, it was found that choroidal rupture can occur without obvious or minor trauma in subtle pseudoxanthoma elasticum (PXE) disease, and based on literature review, this case was considered as a possibility of subtle PXE.
