摘要

目的探讨眼淋巴受累在结膜下出血引流和治疗中的作用。方法我们报告一例63岁的白人女性，在白内障手术中使用结膜下麻醉剂后出现结膜下出血。术中使用光学相干断层扫描对深、中结膜tenon空间内的这些结构进行成像。结果结膜下出血可见，出血部位附近出现囊状充血结构。术中光学相干断层扫描证实了血液存在于结构中，这些结构包含让人想起瓣膜小叶的分区，表明它们起源于淋巴。结膜下出血在术后迅速消退。结论结膜下出血可在结膜淋巴管的辅助下得到解决。我们的研究结果证实，淋巴结构可能在协助结膜下间隙清除大分子方面发挥着被低估的作用。

Drainage of subconjunctival hemorrhage through conjunctival lymphatic pathways

Purpose

To demonstrate the role of ocular lymphatic involvement in aiding the drainage and resolution of subconjunctival hemorrhage.

Methods

We present the case of a 63-year-old Caucasian female who developed a subconjunctival hemorrhage following the administration of a subconjunctival anesthetic during cataract surgery. Intraoperative optical coherence tomography was utilized to image these structures within the deep and middle conjunctival-Tenon's space.

Results

Subconjunctival hemorrhage was visualized and saccular blood-filled structures developed adjacent to sites of hemorrhage. Intraoperative optical coherence tomography confirmed the presence of blood within structures containing partitions reminiscent of valvular leaflets, indicating their lymphatic origin. Rapid resolution of the subconjunctival hemorrhage was noted during the immediate postoperative period.

Conclusion

Subconjunctival hemorrhage may have its resolution assisted by conjunctival lymphatic vessels. Our findings confirm that lymphatic structures may play an under-appreciated role in assisting the clearance of macromolecules from the subconjunctival space.

期刊介绍： The American Journal of Ophthalmology Case Reports is a peer-reviewed, scientific publication that welcomes the submission of original, previously unpublished case report manuscripts directed to ophthalmologists and visual science specialists. The cases shall be challenging and stimulating but shall also be presented in an educational format to engage the readers as if they are working alongside with the caring clinician scientists to manage the patients. Submissions shall be clear, concise, and well-documented reports. Brief reports and case series submissions on specific themes are also very welcome.
