The three animals had a history of recent travel to\/from other countries. The young adult cat imported from Spain presented an intermittent unilateral ocular discharge. During in-depth ophthalmic examination, a single alive nematode was removed from the conjunctival compartment of the affected eye. Referring to the canine cases, an adult female dog originated from Kenya presented epiphora and mucous whitish-grey discharge of the right eye. During flushing of the nasolacrimal duct two small, thin and long nematodes were removed. Furthermore, a male Borzoi racing dog with regular visit to racing tracks in different countries presented ocular mucous discharge. At ophthalmologic examination, two transparent-whitish vital nematodes were removed. All nematode specimens of the three cases were morphologically identified as adult <jats:italic>T. callipaeda<\/jats:italic> parasites. The animals were treated orally with milbemycin oxime (2.0\u00a0mg\/kg; cat) or milbemycin oxime\/praziquantel (0.5\u00a0mg\/kg and 5.0\u00a0mg\/kg; dogs) twice with 1-week interval resulting in complete resolution of symptoms. The repeated introduction of patent <jats:italic>T. callipaeda-<\/jats:italic>infected animals, especially from southern and eastern endemic countries, will ease the establishment of ophthalmic thelaziosis in Northern Europe. The male fruit fly, <jats:italic>Phortica variegata<\/jats:italic>, an intermediate host of <jats:italic>T. callipaeda<\/jats:italic>, is endemic within European countries. Considering the clinical and zoonotic relevance of ophthalmic thelaziosis, enhanced disease awareness of European medical and veterinarian doctors and in-depth eye examination for proper detection of <jats:italic>T. callipaeda<\/jats:italic> are crucial for appropriate anthelmintic treatments and to limit spreading of the infection.<\/jats:p>","DOI":"10.1007\/s00436-020-06785-2","type":"journal-article","created":{"date-parts":[[2020,7,5]],"date-time":"2020-07-05T22:02:31Z","timestamp":1593986551000},"page":"3099-3104","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Ophthalmic Thelazia callipaeda infections: first feline and new canine imported cases in Germany"],"prefix":"10.1007","volume":"119","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2217-9983","authenticated-orcid":false,"given":"Silva","family":"L.
