Experimentally induced Vogt-Koyanagi-Harada disease in two Akita dogs.

We have investigated whether a Vogt-Koyanagi-Harada (VKH)-like disease can be induced in Akita dogs by immunizing them with tyrosinase related protein 1 (TRP1), and compared the alterations induced to those of Akita dogs with a spontaneously occurring disease that resembles human VKH disease. Two Akita dogs were immunized with a peptide mixture of human TRP1. The changes in the eyes were followed by slit-lamp biomicroscopy, ophthalmoscopy, and fluorescein angiography (FA).
