Case history and examination
Four middle aged brachycephalic dogs (three French Bulldogs, one Pug)
were included in the study. The data breed, gender, age and eye are
listed in table 1. All dogs were examined in general clinical and by
slit-lamp-biomicroscopy (SL 17, Kowa company Ltd, Tokyo/Japan).
The general examination of all dogs in this case report revealed extreme
loud breathing and stridor. All owners stated that their dog was very
exercise and heat intolerant. These were signs of a severe respiratory
brachycephalic syndrome.
The slit lamp examination showed typical signs of brachycephalic ocular
syndrome (BOS) in both eyes and a deep stromal ulcer in one eye (fig.
3). Characteristics and causes of the ulcer, detected bacteria, their
sensitivity to antibiotics, duration of third eyelid flap application,
healing time, vision and transparency of the cornea at time during the
last examination are listed in table 1 too.
Corneal bacteriological swab samples were taken in three cases.
Bacterial swabs were positive with a mono-culture of Streptococcus canis
in case 1 and with Streptococcus canis and Enterobacter cloacae in case
3. From the corneal swab sample in one deep melting ulcer (case 4) no
bacteria could be isolated.
