Traumatic Central Retinal Vein Occlusion: A Case Report

Here we report a healthy 48-year-old man who experienced severe loss of vision in the left eye due to central retinal vein occlusion (CRVO) after head trauma. The patient was visited by us three days after the trauma. All systemic workups were normal. Anterior segment examination showed subconjunctival hemorrhage in the left eye. Anterior chamber was deep and clear and intraocular pressure was normal. Relative Afferent Pupillary Defect (RAPD) was negative. A dilated fundoscopic examination of the left eye revealed a moderately congested optic nerve with dilated and tortuous retinal veins scattered throughout the fundus with dot, blot, and flame-shaped hemorrhages. A few yellowish white cotton-wool spots were also seen. A fluorescein angiogram in the left eye confirmed a nonischemic CRVO. Although isolated CRVO following trauma is a rare condition, ophthalmologists should be aware of the potential for blunt head trauma causing CRVO.
