· Heterochromia was observed in a six-month-old Dutch pigmented rabbit and the rabbit was examined for general and eye anomalies. The rabbit showed a blue eye with fundus hypochromia on the right and a brown eye with partial fundus hypochromia on the left. White fur (white forelock) was present, but deafness was not apparent although no objective audiologic examination was performed. Histology studies of both eyes revealed that significantly fewer pigment cells in iris stroma and less pigmentation in retinal pigment epithelium and choroid in the right eye than in the left eye.
