The distribution of pseudo-exfoliation (PE) material as well as the finer details of its surface has been studied by scanning electron microscopy on the surfaces facing the posterior chamber. The specimens were fixed in glutaraldehyde and OSO4 and dried by the critical point method, after careful dissection of the anterior hyaloid surface. Granules and plaques of PE material were found to attach to the iris, to the ridges of the ciliary processes, to the zonules, and along radial stripes on the anterior hyaloid surface, one for each zonule touching this surface. It seems as if the PE material is located mainly on sites on contact between two surfaces. In high mangnification it is found that the surface of the PE material is formed by an irregular meshwork of fibrils, the diameter of which is about 550-700 A. The fibrils are characteristically coiled, partly into regular spirals. The hypothesis is put forward that these fibrils are formed by a condensation of mucopolysaccharides forming the ground substance of the PE material.
通过扫描电子显微镜对面向后房的表面进行研究，分析了假性剥脱（PE）物质的分布及其表面的更细微细节。在仔细解剖前玻璃体表面后，将标本用戊二醛和四氧化锇固定，并采用临界点干燥法干燥。发现PE物质的颗粒和斑块附着于虹膜、睫状突嵴、悬韧带以及前玻璃体表面的放射状条纹上，每条接触该表面的悬韧带对应一条条纹。似乎PE物质主要位于两个表面的接触部位。在高倍放大下发现，PE物质的表面由直径约为550 - 700埃的不规则纤维网构成。这些纤维的特征是呈螺旋状，部分呈规则螺旋。有人提出假说，这些纤维是由构成PE物质基质的粘多糖凝聚形成。
