A Caucasian male in his 40s was referred by his primary care doctor for evaluation after experiencing blurry vision associated with frontal headaches for a week. Despite his headaches, he denied having eye pain. He was otherwise healthy, with no past medical or ocular history. Prior to referral, his symptoms prompted magnetic resonance imaging of the brain, orbits, and cervical spine which were unremarkable. Laboratory test results for the presence of Lyme disease, rapid plasma reagin, antinuclear antibodies, angiotensin-converting enzymes, and erthrocyte sedimentation rates were normal.
