Objective: To examine ultrasonographic abnormalities in eyes with traumatic hyphema obscuring intraocular structures. Design: Retrospective clinical study. Setting: The ophthalmology services of a private practice and university veterinary teaching hospital. Animals: Twenty‐two dogs, 6 cats, 3 horses, and 2 birds. Measurements and main results: Medical records were reviewed for signalment, history, ophthalmic examination, ultrasonographic findings, treatment, and outcome in all patients that presented to the ophthalmology service with trauma‐induced hyphema obscuring intraocular structures. Thirty‐three patients were included and there were 35 affected eyes (17 left and 18 right). Abnormalities noted on ophthalmic examination included hyphema obscuring intraocular details beyond the iris (100%), corneal laceration (23%), iris prolapse (23%), fibrin clotting within the anterior chamber (17%), and subconjunctival and periocular bruising (17%). Ocular ultrasonography revealed the presence of either vitreous hemorrhage or a retinal detachment in 32 of 35 eyes (91%) with traumatic hyphema. Of the remaining 3 eyes, ocular ultrasonography revealed a lens luxation with posterior eye wall rupture in 1 eye and collapsed globes in the other 2 eyes. Twelve eyes were enucleated and 23 were treated medically. Ten of the medically treated eyes were lost to follow‐up. Blindness was noted in all the affected eyes upon their final discharge and recheck examination. Conclusions: Ocular ultrasonography revealed vitreous hemorrhage or a retinal detachment in 32 eyes (91%) with traumatic hyphema. Blindness was noted on the last available examination of every eye. The prognosis for vision in an eye with traumatic hyphema obscuring intraocular detail is poor.
