Purpose:
To report a case of a branch retinal artery occlusion (BRAO) associated with a prepapillary vascular loop in a patient with papilledema.
Observations:
A 22-year-old woman presented with sudden superior visual field loss in the left eye. Initial examination demonstrated mild optic disc edema bilaterally. The diagnosis of idiopathic intracranial hypertension was made and treatment with acetazolamide was initiated. During follow-up examination bilateral prepapillary vascular arterial loops and a BRAO in the left eye were diagnosed. Over time the initially dense superior arcuate visual field defect improved.
Conclusions And Importance:
We report a case of BRAO and prepapillary loops in a patient with coexisting papilledema. The initial symptoms of unilateral visual field loss were falsely attributed to the presence of papilledema and the BRAO was only detected on subsequent examination. The case highlights the importance of correlating the presenting chief complaint with the examination findings to reach the correct diagnosis.
