Fig. 6. Loss of vision after strabismus surgery is very uncommon. This 45-year-old woman had received orbital radiation prior to her strabismus surgery. The surgery was performed with retrobulbar anesthesia. Four days after the operation, vision was decreased from 20/20 to light perception. It is presumed that there was injection of the anesthetic into or around the optic nerve that caused compromise of the central retinal artery. The fundus photograph was taken 4 days after the procedure.
