A 79-year-old male presented with a complaint of decreased visual acuity in his left eye for the past 4 days. He also described a “dirty cobweb” in the left eye that was immobile. He denied flashes, scotomata, and curtains.
The visual acuity OD had been count fingers for the previous 10 years secondary to a presumed branch retinal vein occlusion. He had a history of mild cataracts OU. He was diabetic but there was no history of diabetic retinopathy or other ocular disease.
The patient had originally reported to his primary care physician one week earlier with complaints of increased fatigue, short-term memory loss, lower extremity weakness, and headache. He had been hunting in the Florida panhandle one week prior to the onset of his symptoms and sustained numerous mosquito bites.
