A five-year-old, male castrated, mixed breed dog presented to the Cornell University Hospital for Animals Ophthalmology Service in December 2014 for suspected glaucoma. The owners reported a one month history of red eyes.
On presentation, the patient was hyperthermic. Two paralumbar subcutaneous soft tissue masses with diameters of 2-3 cm were present. On ophthalmic exam, the pupillary light response was sluggish OU. Intraocular pressures were within normal range OU. Deep corneal neovascularization was present OU. Examination of the anterior chamber revealed 1+ aqueous flare and keratic precipitates OU. Posterior synechiae were present OU. Fundic exam revealed bullous retinal detachment with diffuse retinal hemorrhage and suspected subretinal granulomas OU.
Diagnostics included a complete blood count (CBC), chemistry panel, 4DX snap test, urine antigen test for blastomycosis, Brucella canis agar gel immunodiffusion (AGID) test, cytology from aspirates of the subcutaneous masses, thoracic radiographs, abdominal ultrasound, and cytology from splenic aspirates. An underlying etiology was not found, and a presumptive diagnosis of idiopathic panuveitis was made. The patient was started on both systemic and topical prednisolone and oral doxycycline.
