To demonstrate the role of ocular lymphatic involvement in aiding the drainage and resolution of subconjunctival hemorrhage.
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.
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.
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.
证明眼部淋巴管参与在结膜下出血引流和消散中的作用。
我们报告了一例63岁的白种女性患者,在白内障手术中结膜下注射麻醉剂后发生结膜下出血。术中使用光学相干断层扫描对结膜-提上睑肌筋膜深层和中层空间内的这些结构进行成像。
可见结膜下出血,且在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,在含有类似瓣膜小叶的分隔结构内存在血液,表明其起源于淋巴管。术后即刻观察到结膜下出血迅速消散。
结膜下出血的消散可能得到结膜淋巴管的辅助。我们的研究结果证实,淋巴结构在协助从结膜下间隙清除大分子方面可能发挥着未被充分认识的作用。
