The presence of eukaryotic cells in a scraping of an infected cornea suggests the possibility of a parasitic infection, such as Acanthamoeba keratitis.

Herpetic keratitis is caused by the herpes simplex virus and may show viral inclusion bodies, but would not necessarily involve the observation of eukaryotic cells. Ophthalmia neonatorum is a condition of neonatal conjunctivitis caused by exposure to pathogens during birth. Trachoma and trichiasis are both caused by repeated infections with Chlamydia trachomatis, but may not involve the observation of eukaryotic cells.
