Clinical Reasoning: A 62-Year-Old Woman With Transient Vision Loss.

Transient visual loss (TVL) is a common complaint in the Emergency Department, with numerous possible etiologies. Prompt evaluation and management of TVL can potentially prevent progression to permanent visual loss. In this case, a 62-year-old female presented with acute, painless, unilateral TVL. Two weeks prior to presentation, the patient reported bitemporal headaches and paresthesia of the distal extremities. A review of systems revealed chronic fatigue, cough, diffuse arthralgias, and decreased appetite for the previous six months. This case highlights the diagnostic approach to patients with TVL. Some common and rare causes associated with this clinical manifestation are briefly reviewed.
