In the workup, consider toxoplasmosis and multifocal choroiditis with panuveitis as differential diagnoses. Inquiring about possible time spent in the Ohio-Mississippi River Valley area is important. The Amsler grid should be used to assess the central visual field for each eye. Fluorescein angiography or OCT-A may be used to detect a choroidal neovascular membrane.
