The goal of the study was to determine morphological changes of conjunctiva underlying positive vital staining in TED. 46 patients (92 eyes) with TED were included into the study. Besides routine ophthalmologic examination they underwent impression cytology and histology. According to our results positive conjunctival staining in TED is caused by punctuate epithelial erosions and excessive desquamation of superficial cells. Revealed changes are not specific for TED.
