The authors determined the frequency and scleral coordinates of vortex vein exit sites in 46 autopsy eyes to provide topographic data that will enable surgeons to locate these vessels more precisely.
Forty-six autopsy eyes were examined under a dissecting microscope to measure the frequency of vortex veins and the cord lengths between the vortex vein scleral exit sites and the limbus, rectus muscle insertions, and oblique muscle insertions.
Data from this study showed that 32 (70%) of the 46 individual eyes studied had more than four vortex veins. The number of second or third vortex veins found in the nasal quadrants was significantly higher than the number found in the temporal quadrants (P < 0.01). Statistical analyses of the measurements provided mean values for distances between vortex vein scleral exit sites and the three nearest extraocular muscle insertions; these positions among eyes were found to be relatively uniform (standard deviation, 0.7-2.5 mm).
The authors suggest that the majority of adult eyes encountered by a surgeon will have more than four vortex vein exit sites and that more vortex veins may be expected in the nasal quadrants than in the temporal quadrants. This study delineates the locations of vortex vein exit sites so that surgeons can reliably predict their surface positions to avoid vessel laceration and its ensuing complications.
作者测定了46只尸眼涡静脉穿出部位的频率和巩膜坐标，以提供地形学数据，使外科医生能够更精确地定位这些血管。
在解剖显微镜下检查46只尸眼，测量涡静脉的频率以及涡静脉巩膜穿出部位与角膜缘、直肌附着点和斜肌附着点之间的索带长度。
本研究数据显示，在研究的46只眼中，有32只（70%）的涡静脉超过4条。在鼻象限发现的第二或第三涡静脉数量显著高于颞象限（P<0.01）。对测量数据的统计分析提供了涡静脉巩膜穿出部位与三个最近眼外肌附着点之间距离的平均值；发现这些位置在各眼之间相对一致（标准差为0.7 - 2.5毫米）。
作者认为，外科医生遇到的大多数成年眼的涡静脉穿出部位会超过4个，并且预计鼻象限的涡静脉比颞象限更多。这项研究描绘了涡静脉穿出部位的位置，以便外科医生能够可靠地预测其表面位置，避免血管撕裂及其随之而来的并发症。
