Myxomatous embolization resulting in unilateral amaurosis.

A patient with sudden, painless monocular blindness is an uncommon emergency department presentation. Despite often futile attempts to treat the blindness, most clinicians search for a source of possible embolization. A patient is presented that developed monocular blindness without a clinically apparent source. Advanced diagnostic imaging showed a previously undetected atrial myxoma. The salient clinical features, diagnostic techniques, and therapeutic interventions for this uncommon cardiac tumor are discussed.
