We describe a case of recurrent spontaneous vitreous haemorrhage due to congenital retinal arterial loop. The pre-optical coherence tomography showed the loop to be intraretinal rather than pre retinal. Thus the term pre retinal arterial loop is a misnomer. The arterial loop is in the superficial layer of retinal nerve fiber layer. We also demonstrated preretinal posterior hyaloid tissue attached on the retinal arterial loop, which may be the cause of traction and spontaneous recurrent VH.
我们描述了一例因先天性视网膜动脉环导致的复发性自发性玻璃体出血病例。光学相干断层扫描术前显示该环位于视网膜内而非视网膜前。因此,视网膜前动脉环这一术语是用词不当。动脉环位于视网膜神经纤维层的浅层。我们还证实视网膜动脉环上附着有视网膜后玻璃体前界膜组织,这可能是牵拉和自发性复发性玻璃体出血的原因。
