Organized Lymphoid Tissue in EALT

Organized lymphoid follicles in the human conjunctiva have been reported in different numbers in individuals with a macroscopically normal conjunctiva (as reviewed in [28]). Apart from the fact that most of these studies investigated only small tissue biopsies or selected con-junctival areas which do not represent the whole organ as found later, the amount of follicles also varies with age [44].

Recent results in normal whole-mount tissues of the human conjunctiva have shown that even in an old age population about 60 % of tissues contain organized lymphoid follicles with a distinct topographical distribution. They cumulate in the tarso-orbital zone and have a high (>80%) bilateral symmetry [28]. In the lacrimal drainage system, a similar lymphoid tissue occurs and was termed, according to the international nomenclature, lacrimal drainage-asso ciated lymphoid tissue (LDALT) [22] with lym-phoid follicles in roughly half of the tissues (about 41% [45], 44% [22] or up to 56% of old age body donors [24]).
