A 3-year-old, intact male, mixed breed dog was presented with a complaint of acute blindness. Ten days previously, the area where the dog was walking came under a rocket attack, and a rocket landed and exploded 300 meters away from the dog. Physical examination was unremarkable. Ophthalmoscopic examination revealed posterior segment fibrin clots and extensive vitreal hemorrhage in the right eye. A total retinal detachment (360 degrees retinal dialysis) with no evidence of hemorrhage was noted in the left eye. There was no sign of any penetrating ocular trauma, and it was assumed that the posterior segment findings were primary injuries caused by the blast wave itself. Following anti-inflammatory treatment, partial vision was restored in the right eye. Surgical re-attachment of the retina was discussed and declined by the owner. This report describes, for the first time, vitreal hemorrhage and retinal detachment as the sole injuries caused by an explosive blast wave.
