一名儿童非孔源性视网膜脱离与牵牛花盘进行了第一次玻璃体切除术，然后，几个月后，视神经鞘开窗。后一种手术导致视网膜复位。它还产生了一个活检标本，证实了在这种情况下，低分化的视网膜组织的神经周围出血，类似于先天性视神经小窝。从组织学上以及通过睫状体平坦部注入玻璃体腔的气体在视神经鞘中从窗口冒出的事实证明了玻璃体腔与神经周围空间的连续性。作者认为，牵牛花盘和视凹具有相似的解剖学特征，不同程度多于种类，并且在这些情况下，视神经周围的低分化组织的多孔性突出到蛛网膜下腔，使得视网膜下液的几个来源成为可能。
A child with nonrhegmatogenous retinal detachment associated with morning glory disc underwent first a vitrectomy and then, some months later, an optic nerve sheath fenestration. The latter procedure led to retinal reattachment. It also produced a biopsy specimen that confirmed the perineural hemiation of poorly differentiated retinal tissue in this condition, similar to that in congenital pit of the optic nerve. It demonstrated continuity of the vitreous cavity with the perineural space, both histologically and by the fact that gas injected through the pars plana into the vitreous cavity bubbled out the window in the optic nerve sheath. The authors suggest that morning glory disc and optic pit share similar anatomic features, differing more in degree than in kind, and that the porous nature of the poorly differentiated tissue herniated around the optic nerve into thesubarachnoid space in these conditions makes several sources of subretinal fluid possible.
