PURPOSE
To describe features characteristic of vitreous hemorrhage in patients with Terson syndrome observed through a microsurgical scope.
METHODS
Between May 2015 and February 2019, 12 eyes of 10 patients with vitreous hemorrhage occurring after subarachnoid hemorrhage (SAH) underwent pars plana vitrectomy.
RESULTS
During vitreous surgery, we found 10 of 12 eyes did not have posterior vitreous detachment (PVD). Furthermore, we observed in 9 of the 10 eyes without PVD (90.0%) that there was no hemorrhage in the posterior vitreous cavity at the posterior pole while we removed vitreous hemorrhage. We confirmed that this clean space could be the posterior precortical vitreous pocket (PPVP).
CONCLUSION AND IMPORTANCE
Terson syndrome may have no hemorrhage in the PPVP regardless of the presence of severe vitreous hemorrhage. The cases presented in our study may suggest one of the mechanisms of Terson syndrome.
目的
描述通过显微手术显微镜观察到的Terson综合征患者玻璃体积血的特征。
方法
2015年5月至2019年2月，对10例蛛网膜下腔出血（SAH）后发生玻璃体积血的患者的12只眼进行了玻璃体切除术。
结果
在玻璃体手术过程中，我们发现12只眼中有10只没有玻璃体后脱离（PVD）。此外，在10只没有PVD的眼中，有9只（90.0%）在清除玻璃体积血时后极部玻璃体后间隙没有出血。我们证实这个无血空间可能是皮质下玻璃体后间隙（PPVP）。
结论及意义
无论是否存在严重玻璃体积血，Terson综合征患者的PPVP可能都没有出血。我们研究中的病例可能提示了Terson综合征的一种发病机制。
