Research output: Contribution to journalArticle


The aim of this study was to assess the morphology of superficial bulbar conjunctival cells collected by impression cytology or by scraping.
Freshly procured sheep eyes from a slaughterhouse were washed and then conjunctival impression cytology (CIC) samples taken from the nasal aspect of the bulbar conjunctiva on a Biopore Millicell filter unit, or cells scraped from the same location and smeared onto glass slides. After alcohol fixation, all samples were stained with Giemsa. Cell images were obtained by light microscopy at 200× magnification, and subjected to morphometry.
