视网膜周边部囊胞样变性是对于摘出的眼球锯齿缘附近见到的小囊胞样病变所引起的病理组织学名称,也有的报告者称为Blessig囊-Iwanoff囊胞。在外网状层形成的小囊胞腔,它们可相互融合,在视网膜内形成复杂的网眼状隧道。这种隧道靠从视网膜内层向外层伸长的多数细柱支撑着。在临床上,若用检眼镜观察视网膜周边部囊胞样变性,在视网膜锯齿缘的稍后面可见到小的红颗粒状 Cystic degeneration of the peri-retinal area is a histopathological name for the cystic-like lesions seen near the extirpated ocular jagged edges, and some authors report it as Blessig sac-Iwanoff cysts. In the outer reticular layer formed small cell cavities, they can be integrated with each other in the retina to form a complex mesh tunnel. The tunnel is supported by many thin columns extending from the inner retina to the outer layer. Clinically, if ophthalmoscopy is used to observe cystic degeneration of the peripheral portion of the retina, a small red granule may be seen slightly behind the serrate edge of the retina
