我们用生物显微镜检查了视神经与玻璃体之间的关系，在16个连续的视神经凹陷患者的17只眼睛中，表现出与黄斑相关的浆液性脱离。后玻璃体附着15眼（88%）；后玻璃体部分脱离，两条眼的玻璃体链终止于视窝（12%）。在无后玻璃体脱离的15只眼中，11只（73%）有异常的Cloquet管，其明显浓缩并终止于眶窝边缘。在眼球运动中，我们观察到异常的Cloquet管前后运动，并观察到覆盖眶窝的半透明膜的脉动。我们的研究结果表明，异常Cloquet管对视神经窝的玻璃体内牵引可能在黄斑脱离的发展中起作用。
We examined biomicroscopically the relationship between the optic nerve and the vitreous in 17 eyes of 16 consecutive patients with pits of the optic nerve that demonstrated an associated serous detachment of the macula. The posterior vitreous was attached in 15 eyes (88%); the posterior vitreous was partially detached with a vitreous strand terminating at the optic pit in two eyes (12%). Of the 15 eyes without posterior vitreous detachment, 11 (73%) had an anomalous Cloquet's canal that was markedly condensed and terminated at the margin of the pit. During ocular movement, we observed a back-and-forth movement of the anomalous Cloquet's canal and a pulsating translucent membrane that covered the pit. Our findings suggest that the intravitreal traction on the optic pit by the anomalous Cloquet's canal may have a role in the development of macular detachment.
