A 14-year-old girl developed spontaneous vitreous hemorrhage from the free end of a partially regressed hyaloid artery. Fluorescein angiography confirmed the hemorrhage was from the retinal arterial rather than venous circulation. The vessel became a fibrosed, occluded, and semitransparent thread after 20 months of follow-up evaluation. It was postulated that the rapid eye movement (REM) phase during sleep may create a tractional force and leads to rupture of the freely floating hyaloid artery. A patent persistent hyaloid artery should be included in the list of the causes of vitreous hemorrhage, especially in healthy young people.
一名14岁女孩因部分退化的玻璃体动脉游离端出现自发性玻璃体出血。荧光素血管造影证实出血来自视网膜动脉而非静脉循环。经过20个月的随访评估，该血管变成了一条纤维化、闭塞且半透明的条索。据推测，睡眠期间的快速眼动（REM）阶段可能产生牵拉力，导致自由漂浮的玻璃体动脉破裂。永存玻璃体动脉通畅应列入玻璃体出血的病因清单中，尤其是在健康的年轻人中。
