Clinical, neurophysiological, biochemical and morphological features of eyes in Persian cats with mannosidosis.

The clinical, neurophysiological, morphological and biochemical manifestation of eyes from Persian kittens affected with alpha-mannosidosis were studied. Clinically the disease is characterized by progressive corneal and lenticular opacification. In addition there is asymmetry in shape and latency of signal conductions which were demonstrated by visual evoked potential studies. Morphological and histochemical studies revealed vacuolization of various ocular cell types which stained positively with Concanavalia ensiformis agglutinin (Con A) and wheat germ agglutinin (WGA). Biochemical studies illustrated low activity of acid alpha-mannosidase in cultured keratocytes and abnormal storage of partially degraded oligosaccharides in these cells, in vitreous humor and lens. This comprehensive study of ocular alpha-mannosidosis demonstrates enzyme deficiency which leads to abnormal storage of oligosaccharides in affected cells and is manifested by morphological alterations and functional impairment.

Ketoconazole therapy in a dog with systemic cryptococcosis.

A 2-year-old dog had bilateral chorioretinitis and a cough. Systemic cryptococcosis was diagnosed by evaluating a trans-tracheal aspirate and a cryptococcal latex-particle agglutination antigen titer. Clinical remission was achieved with ketoconazole administration, an imidazole antifungal agent. Serial antigen titers were used to monitor treatment, which was continued for 12 months. Ketoconazole therapy was well tolerated by the dog.

Keratoconjunctivitis sicca associated with sulfonamide therapy in dogs.

During a 4-year period, keratoconjunctivitis sicca developed in 14 dogs treated with sulfonamides (13, sulfasalazine; 1, sulfadiazine and trimethoprim). Diagnosis was made in 3 dogs by clinical signs and in 11 by evaluation of the Schirmer tear test. Management of the problem included discontinuance of the sulfonamide, then use of ophthalmic preparations topically and antibiotics systemically. Pilocarpine was administered orally and topically to 11 dogs, with variable success. Lacrimation remained inadequate in 10 dogs and returned to normal in 3. One dog was lost to follow-up. Parotid salivary duct transpositions were performed in 3 dogs (in 2 successfully) with severe, unresponsive keratoconjunctivitis sicca.
