Blindness characterized by dilated, unresponsive pupils and ophthalmoscopic evidence of optic nerve atrophy and retinal degeneration developed in a 5-year-old llama. Lesions were not progressive during 2 months of observation. The llama was euthanatized and necropsied. Histopathologic findings included chorioretinitis, optic neuritis, and encephalitis characterized by mononuclear perivascular infiltration. Attempts to prove an infectious cause were unsuccessful.
