Cilioretinal arteries were noted to accompany pits of the optic disc in 16 of 25 cases (64%). Fourteen of the 16 cases were found to have 2 cilioretinal arteries (86%). The cilioretinal arteries were directly related to the pit of the disc and emerged either from the bottom or the margin of the pit in a proportion of 86%. This finding reinforces the assumption that the optic disc pit belongs to the same spectrum of congenital anomalies which also includes optic disc coloboma, megalopapilla and morning glory syndrome. A fluorescein angiography study showed hyperfluorescence of the pit in 12/16 cases and in particular in all the cases in which both cilioretinal arteries emerged from the pit. Hypofluorescence was noted in 7/9 cases in which the pit was not associated with cilioretinal arteries. Our findings could support the view that hyperfluorescence of the pit, which is not a constant phenomenon, mostly depends on the presence of cilioretinal arteries emerging from the pit.
在25例患者中，有16例（64%）发现睫状视网膜动脉与视盘凹陷相伴。这16例中有14例（86%）有2条睫状视网膜动脉。睫状视网膜动脉与视盘凹陷直接相关，86%的情况下从凹陷底部或边缘发出。这一发现强化了视盘凹陷属于先天性异常范畴的假设，该范畴还包括视盘缺损、视乳头过大和牵牛花综合征。荧光素血管造影研究显示，16例中有12例视盘凹陷呈高荧光，特别是在两条睫状视网膜动脉均从凹陷发出的所有病例中。在9例视盘凹陷与睫状视网膜动脉无关的病例中，有7例出现低荧光。我们的发现支持这样一种观点，即视盘凹陷的高荧光并非恒定现象，主要取决于从凹陷发出的睫状视网膜动脉的存在。
