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. 相似文献

Objective: Glaucoma is an optic nerve disease that may result in rapid loss of vision. Early detection of acute glaucoma and aggressive treatment is important to preserve vision. Continued treatment is indicated in chronic glaucoma to alleviate discomfort associated with chronic elevated intraocular pressure.
Etiology: In primary glaucoma, an abnormal iridocorneal angle results in obstruction to outflow of aqueous humor. In secondary glaucoma, an otherwise normal iridocorneal angle is obstructed by abnormalities such as a luxated lens, neovascular membranes or inflammatory material.
Diagnosis: The diagnosis is made by a combination of clinical signs such as corneal edema, mydriasis, decreased vision, episcleral hyperemia, and confirmed by measuring an elevation in intraocular pressure. Complete ophthalmic examination, knowledge of breed predisposition to various ocular diseases and gonioscopy will aid in distinguishing between primary and secondary glaucoma
Therapy: Aggressive medical management is important in acute glaucoma. Surgical procedures are often indicated after initial emergency medical treatment of acute glaucoma. Chronic, painful blind eyes are best treated with one of various surgical procedures.
Prognosis: The prognosis for maintaining vision or regaining temporarily lost vision in acute glaucoma is related to numerous factors including time between onset of clinical signs and appropriate treatment, etiology of the glaucoma, initial response to therapy and client compliance. 相似文献
