PURPOSE/METHODS: We examined a 23-year-old woman who had a sudden onset of floaters after self-induced emesis.
RESULTS/CONCLUSIONS: Examination showed a dense vitreous hemorrhage originating from a rupture site in the wall of the superotemporal branch vein. We postulate a preexisting weakness in the retinal vein wall as a predisposing factor to rupture. This mechanism may explain some cases of vitreous hemorrhage associated with a Valsalva maneuver.
目的/方法：我们检查了一名23岁女性，她在自我催吐后突然出现飞蚊症。
结果/结论：检查发现致密的玻璃体积血，起源于颞上支静脉壁的破裂部位。我们推测视网膜静脉壁预先存在的薄弱是破裂的易感因素。这一机制可能解释了一些与瓦尔萨尔瓦动作相关的玻璃体积血病例。
