证明春季结膜炎在穹窿结膜的临床病理。方法：详细记载球（角膜缘）、睑及穹窿结膜的临床表现；对３８眼（２１例）的穹窿结膜（上穹窿３４眼、下穹窿４眼）进行活检，组织切片ＨＥ染色，光学显微镜下观察病理改变。结果：结膜上皮不同程度增生，上皮下淋巴细胞、浆细胞浸润或胶元纤维增生，３８眼标本中３２眼有嗜酸性白细胞、１眼有嗜碱性白细胞浸润。一极轻病例双眼下穹窿结膜只有很少几个淋巴细胞，其中却散在个别嗜酸性白细胞。结论：春季结膜炎的临床病理改变包括穹窿结膜。 Prove the clinical pathology of conjunctivitis in the fornix conjunctiva. Methods: The clinical manifestations of the ball (limbus), eyelid and fornix conjunctiva were recorded in detail. Biopsy was performed in 38 eyes (21 cases) of fornix conjunctiva (34 eyes of superior dome and 4 eyes of inferior fornix). Tissue sections were stained with HE. Observe the pathological changes. Results: There were hyperplasia of conjunctival epithelium, subepithelial lymphocytes, plasma cell infiltration or collagen fiber hyperplasia. Thirty - two eyes of 38 eyes had eosinophilic leukocytes and one had basophilic leukocyte infiltration. In an extremely mild case, there are only a few lymphocytes in the inferior fornix conjunctiva, scattered among individual eosinophils. Conclusion: The clinical pathological changes of spring conjunctivitis include fornix conjunctiva.
