Retinal Changes in a Patient with a Traumatic Orbital Subperiosteal Hematoma and Superior Ophthalmic Vein Compression

Purpose: We describe a case with retinal alterations similar to those of nonischemic central retinal vein occlusion, but also with superior ophthalmic vein compression attributable to a traumatic, subperiosteal orbital hematoma.Case summary: A 13-year-old male presented with left periorbital edema, a decrease in vision, and diplopia after blunt periorbital trauma. In ophthalmological evaluations, the best-corrected visual acuity (BCVA) was 0.4 (20/50) and a severe supraduction limitation was apparent (grade -4). Fundus examination revealed optic disc swelling, retinal vein dilation/tortuosity, and an arteriovenous transit time delay of 26s. Fluorescein angiography evidenced optic disc leakage. Ocular sonography and orbital magnetic resonance imaging revealed a superior subperiosteal hematoma in the left orbit accompanied by superior ophthalmic vein compression. We scheduled emergency hematoma evacuation. One month later, the BCVA had increased to 1.0 (20/20) and ocular movement was no longer limited. Orbital computed tomography showed that the superior ophthalmic vein compression had resolved and that the abnormalities observed in the initial fundus examination and fluorescein angiography had improved.Conclusions: Retinal changes that resemble nonischemic central retinal vein occlusion including retinal venous dilation and tortuosity may develop after a traumatic, orbital subperiosteal hematoma. Compressive obstruction of the superior ophthalmic vein may then be in play. Early surgical intervention featuring hematoma evacuation may prevent irreversible visual deterioration.
