Idiopathic Horner's syndrome in collie dogs.

Seven cases of idiopathic Horner's Syndrome in the Collie are described. Five males and two females presented with unilateral miosis, ptosis of the upper eyelid, enophthalmos and protrusion of the third eyelid. Thorough examination, pharmacological testing with phenylephrine, complete blood counts and radiography of the tympanic bullae and thorax were performed. The etiology was not identified in any of the cases. Clinical signs improved with pharmacologic testing within 20-40 min. In five dogs, total resolution of clinical signs was observed at 4 and 16 weeks after their initial appearance. Pharmacological testing suggested that the deficit could be at the preganglionic neuron.

Uveodermatological syndrome (Vogt-Koyanagi-Harada-like syndrome) with generalized depigmentation in a Dachshund.

A 3-year-old, female, black and tan Dachshund was referred with visual impairment, bilateral anterior and posterior uveitis, poliosis, and generalized dermal depigmentation. Complete blood counts and biochemical parameters, including T3 and T4, were normal. The skin biopsy showed lichenoid dermatoses with dermal infiltration of histiocytes and lymphocytes suggesting uveodermatological syndrome. Medical treatment was initiated with oral prednisone and azathioprine, and topical prednisolone and atropine. The clinical signs improved, vision was retained, and the skin began to repigment 2 months following the initiation of therapy.
