The Utility of Ocular Imaging in Traumatic Optic Nerve Avulsion: A Case Report

Objective: To describe a detailed presentation and the utility of ocular imaging, both ultrasound orbital computed tomography (CT), to confirm diagnosis traumatic ONA in which megadose steroid would give no advantage. Case Presentation: A five-year-old boy came with unilateral sudden visual loss after incidentally falling his left eye struck handlebar parked bicycle. His had light perception, ophthalmoplegia, showing 4+ relative afferent pupillary defect. hallmark "pit" sign pale retina without tear were noted. B-scan displayed retinal step sign, vitreous hemorrhage front optic canal, lamina cribrosa defect, edematous retina, retracted nerve. Orbital scan showed disruption nerve-globe junction. Steroid infusion was decided not be given. Conclusion: Ocular especially ultrasound, along thorough examination, is satisfactorily adequate ONA.
