We examined the vitreous of 84 human autopsy eyes by biomicroscopy after staining the gel component with fluorescein and immersing the specimen in water. A noteworthy finding was the presence of a posterior precortical vitreous pocket that was basically located immediately anterior to the posterior fundus surrounded by the temporal vascular arcades. The posterior wall of the posterior precortical vitreous pocket was composed of a thin layer of vitreous cortex. The anterior border was contoured by the formed vitreous. The posterior precortical vitreous pocket seemed to expand or become confluent with adjacent lacunae in the vitreous. The posterior precortical vitreous pocket was present in all of 48 eyes with no or incomplete posterior vitreous detachment and in 19 of 36 eyes with posterior vitreous detachment. An oval-shaped defect of the premacular cortical vitreous was seen in 10 of 36 eyes with posterior vitreous detachment. The posterior precortical vitreous pocket was consistently present in front of the macula regardless of the type of vitreous liquefaction.
我们通过生物显微镜检查了84只人类尸检眼的玻璃体，方法是先用荧光素对凝胶成分进行染色，然后将标本浸入水中。一个值得注意的发现是存在一个皮质前玻璃体后间隙，它基本位于眼底后部紧邻颞侧血管弓的前方。皮质前玻璃体后间隙的后壁由一层薄薄的玻璃体皮质组成。其前缘由已形成的玻璃体勾勒出轮廓。皮质前玻璃体后间隙似乎会扩张或与玻璃体中相邻的腔隙融合。48只无玻璃体后脱离或玻璃体后脱离不完全的眼中均存在皮质前玻璃体后间隙，36只发生玻璃体后脱离的眼中有19只存在该间隙。36只发生玻璃体后脱离的眼中，有10只可见黄斑前皮质玻璃体呈椭圆形缺损。无论玻璃体液化的类型如何，皮质前玻璃体后间隙始终存在于黄斑前方。
