Senile retinoschisis was found in 30 out of 315 pairs of eyes taken from cadavers. The retinal splitting occurred primarily as a result of the confluence of peripheral cystoid degeneration (Blessig's spaces or Iwanoff's cysts). There is no reason to suppose that two different forms of retinoschisis are present if the vessels are located in the inner layer. Based on reticular cystoid degeneration, there was only once case which could have represented another types of splitting. Here the vessels were located in the outer layer; the inner layer consisted only of the vitreous membrane. External spaces in the layer are the main causal factor for the development of retinoschisis detachment.
在取自尸体的315只眼中，有30只发现存在老年性视网膜劈裂。视网膜劈裂主要是由于周边囊样变性（布累西格间隙或伊万诺夫囊肿）融合所致。如果血管位于内层，就没有理由认为存在两种不同形式的视网膜劈裂。基于网状囊样变性，只有1例可能代表另一种类型的劈裂。在此例中，血管位于外层；内层仅由玻璃体膜组成。该层中的外部间隙是视网膜劈裂脱离发展的主要病因。
