Histopathology of a clinically observed pipestem sheathed vessel in the retina was studied by electron microscopy. This vessel was characterized by a marked increase and disarrangement of collagen fibrils in the media and adventitia, and invasion of the cytoplasmic processes of Müller cells into the adventitia. The lumen of the vessel was extremely narrow but was preserved with healthy endothelial cells. It is suggested that increased and disarranged collagen fibrils in the vessel wall is related mainly to the ophthalmoscopic appearance of the pipestem sheathing. The infiltration of glial cells in the vessel wall may be of less significance to the pipestem sheathing.
通过电子显微镜研究了临床上观察到的视网膜中烟斗柄样鞘状血管的组织病理学。该血管的特征是中膜和外膜中胶原纤维显著增加且排列紊乱，以及 Müller 细胞的胞质突起侵入外膜。血管腔极其狭窄，但保留有健康的内皮细胞。提示血管壁中胶原纤维增加和排列紊乱主要与烟斗柄样鞘膜的检眼镜表现有关。血管壁中胶质细胞的浸润对烟斗柄样鞘膜的意义可能较小。
