Fundus photograph, left eye. Macular whitening with a foveal cherry-red spot can be observed in the affected eye. Also present are two foci of intraretinal hemorrhage and two Roth spots in the macular periphery.

Roth spots in the macular periphery (Figure 1). Retinal vessels were of normal caliber with no visible emboli or boxcar segmentation.
Macular optical coherence tomography. Imaging demonstrates a significant increase in central subfield thickness with obliteration of the foveal contour. Edema and hyperreflectivity obscure the distinction between the inner retinal layers.

Macular OCT demonstrated hyper-reflectivity of the inner retina with edema and a loss of definition between layers (Figure 2).
Brain magnetic resonance imaging with contrast. A circumscribed lesion with ring enhancement and hyperintensity on the T1-weighted image (a) with surrounding edema visible on the T2-weighted image (b).
