[Untersuchung des Tränenfilms und histologische Untersuchung der Augenlider von Möpsen].

Objectives: To determine if qualitative tear film and histological changes of the eyelid margins in pugs compared to other brachycephalic dogs could be potential contributing factors to the high prevalence of corneal diseases in this breed.

Methods: Ophthalmic examin ation (including tear film break-up time [TFBUT] and meibometry) was undertaken on three groups (pugs with and without ophthalmologic abnormalities as well as on other brachycephalic breeds with history of ophthalmologic abnormalities). Histology of eyelid tissue obtained during medial canthoplasty was performed, using hematoxylin-eosin and oil-red-O-staining.
