The Harderian gland is located in the eye orbit and is part of orbital glands complex. The gland is present in almost all vertebrates, i.e., amphibians (except the completely aquatic ones), reptiles, birds, mammals, but not in fish. Among mammals it was described in the Marsupialia and most Eutheria. This review includes data on the Harderian gland structure and cytology of its secretory epithelium. Location of the gland in the eye orbit, its structure and relative size vary in different mammals. Ultrastructural characteristics of its epithelial cells also vary. There are structural differences not only between protein-, mucus- and lipid-synthesizing cells, but within each of these groups too. The chemical nature of the Harderian gland secretory product is species specific.
哈德氏腺位于眼眶内，是眶腺复合体的一部分。几乎所有脊椎动物都有该腺体，即两栖动物（完全水生的除外）、爬行动物、鸟类、哺乳动物，但鱼类没有。在哺乳动物中，有袋类动物和大多数真兽类动物都有该腺体。这篇综述涵盖了哈德氏腺的结构及其分泌上皮细胞的细胞学数据。该腺体在眼眶中的位置、结构和相对大小在不同哺乳动物中有所不同。其上皮细胞的超微结构特征也存在差异。不仅蛋白质合成细胞、黏液合成细胞和脂质合成细胞之间存在结构差异，而且在这些细胞组中的每一组内部也存在差异。哈德氏腺分泌产物的化学性质具有物种特异性。
