The conjunctiva of the dog has a smooth surface on the inside of the upper and lower lid and of the bulbus oculi. In these areas the conjunctiva is covered by a stratified squamous epithelium, the polygonal surface cells of which have microvilli and microplicae which are different in number and show a great variety of shapes. In the passage towards the fornix conjunctivae a stratified cuboidal epithelium is to be discerned. In the fornix itself, the conjunctiva is arranged in small folds which are protruded by goblet cells and the openings of lacrimal glands. Here a stratified cuboidal or columnar epithelium can be observed which at the electron microscopic level shows in all epithelial layers--mostly however in the stratum superficiale--morphological signs of enhanced metabolic activities. The bulbar surface of the third eyelid which is covered by a stratified squamous epithelium has a three-dimensional moulded pattern of pads and grooves. The structure of the conjunctival epithelium to some extend is age dependent.
犬的结膜在上、下眼睑内侧以及眼球表面具有光滑的表面。在这些区域，结膜被复层鳞状上皮覆盖，其多边形表面细胞具有数量不同且形状各异的微绒毛和微褶。在向结膜穹窿移行的过程中，可辨认出复层立方上皮。在结膜穹窿本身，结膜呈小皱襞排列，有杯状细胞和泪腺开口突出。此处可观察到复层立方或柱状上皮，在电子显微镜下，所有上皮层——但主要是表层——均显示出代谢活动增强的形态学迹象。第三眼睑的眼球表面被复层鳞状上皮覆盖，具有垫和沟的三维模压图案。结膜上皮的结构在一定程度上取决于年龄。
