意大利米兰IRCCS Ospedale San Raffaele大学眼科系的Romano F近日在Optom Vis Sci发表了一篇文章,他们在脉络膜毛细血管和视网膜血管丛患者双侧牵牛光盘异常的情况下,通过光学相干断层扫描血管造影的方法,描述视神经盘血管改变的过程。

意大利米兰IRCCS Ospedale San Raffaele大学眼科系的Romano F近日在Optom Vis Sci发表了一篇文章,他们在脉络膜毛细血管和视网膜血管丛患者双侧牵牛光盘异常的情况下,通过光学相干断层扫描血管造影的方法,描述视神经盘血管改变的过程。

牵牛花盘异常是一种视盘的先天性异常。光学相干断层扫描血管造影显示,这种病症具有浅表和深层毛细血管丛的血管稀疏和径向毛细血管周围毛细血管丛的血管增加的症状。他们推测这种充血代表了异常血管发生的代偿机制。

一名24岁的白人到他们的眼科部门(米兰San Raffaele医院)就诊,患者称他的左眼视力下降,而他的右眼视力下降并不明显(20/20)。眼底镜检查显示,双侧漏斗状视神经盘凹陷,中央有大量胶质组织,视网膜血管从椎间盘缘径向出现,在左眼中更为明显。这些症状被认为与双侧牵牛花盘异常有关。视盘的光学相干断层扫描血管造影显示,周围毛细血管浅层、深层毛细血管丛和脉络膜毛细血管具有明显的血管稀疏症状,而桡动脉周围毛细血管网的血管增加。

基于这些观察,他们认为,桡动脉周围毛细血管丛的充血可能是由于牵牛花盘异常引起的血管发生的补偿机制,这种异常的血管发生机制导致患者患病。
