A four-year-old Yorkshire Terrier presented with a relatively sudden onset unilateral (left) painful eye. There were no other problems but the owners considered that the dog had experienced some discomfort during the previous 2 days. On the morning of the consultation there had been marked blepharospasm and excessive lacrimation. Examination revealed conjunctival and episcleral congestion and a diffuse mild corneal edema. There was a faint misty appearance to the anterior chamber and the pupil was constricted.
