Özet
Case PresentationA 29-year-old man was referred to the emergency department with periorbital edema, pain, and sudden loss of vision in the right eye following blunt trauma with a compressed air hose.In ophthalmological examination, visual acuity in the right eye was no light perception.The right pupil was dilated and nonreactive to light.Proptosis, chemosis, conjunctival laceration, and subconjunctival air bubbles were observed on anterior segment examination of the right eye.The cornea and lens were clear. Posterior segment examination revealed the presence of retinal AbstractA 29-year-old man presented with a sudden loss of vision after a closed-globe injury.At presentation, he had no light perception in the right eye and the right pupil was dilated and nonreactive to light.On ophthalmological examination, the area of the optic nerve head was excavated, suggesting optic nerve avulsion.Magnetic resonance imaging scan showed optic nerve avulsion without rupture of the optic nerve sheath.Four months after the injury, the patient's visual acuity remained unchanged.Gliosis developed at the avulsion site.Closed-globe injuries may cause severe posterior injury even if there is no anterior damage in the eye.To prevent unnecessary treatment, trauma patients should be examined carefully appropriate imaging to confirm the diagnosis.
