An ocular fistula in association with frontal abscess in a dog
Case study: A 3-year-old rottweiler dog was given an at-home veterinary service for massive bloody ocular and nasal discharges, which made the animal unable to have proper vision and breath. At first glance, the dog had a swollen head and neck, and was in huge pain, which made the situation inappropriate for examination. So it was decided to sedate the dog. A combination of Ketamine and Acepromazine was used intramuscularly. Having the dog sedated, with caution, the ocular discharges were clean using cotton. Ocular examination revealed that the cornea was intact, however, the substantial conjuctivitis was evident.
We had a suspicion that the dog was bitten, but, by what. Taking a comprehensive history and visiting the kennel, we were convinced that he had a bee sting, as the sting site was found just above the right eyelid. Unfortunately, secondary infection had caused a massive frontal abscess which gradually opened its way into the right orbit so that the discharges were drained off from the eye and nostril of the same side.
The dog was then put on: Penicillin + streptomycin, enrofluxacin, meloxicom and chlorpheniramine, for three consecutive days.
The following day, the dog had another at-home visit. The frontal and neck swelling was reduced to half. There was no sign of ocular and nasal discharge. Conjunctivitis of the right eye was less and the eye was more open. Then medication was switched to Clindamycin 300 mg and Cephalexine 500 mg. Eye examination was performed few times for possible neurological induced keratoconjunctivitis sica (KCS). He gradually recovered and returned to normal.
