Abstract
To report the imaging findings of a single case of paracentral acute middle maculopathy associated with bilateral Purtscher-like retinopathy in the setting of recent viral illness.
Case report, multimodal imaging.
A 21-year-old woman who awoke with sudden-onset bilateral finger count vision in the setting of a recent viral illness. Initial examination and imaging was consistent with a bilateral Purtscher-like retinopathy with evidence of paracentral acute middle maculopathy and ellipsoid zone thickening and hyperreflectivity on spectral domain optical coherence tomography (OCT). Baseline fluorescein angiography and OCT angiography revealed normal perfusion and flow, respectively. All laboratory investigation was negative for possible causative etiology. The patient was followed for 6 months with steady visual improvement to 20/20 in both eyes. En face OCT demonstrated near-complete restoration of the ellipsoid layer. The patient still noted bilateral scotomas which were mapped out on microperimetry and found to correlate to en face OCT findings.
Purtscher-like retinopathy in the setting of recent viral illness is a rare cause of vision loss that may be associated with the finding of paracentral acute middle maculopathy on spectral domain OCT. Despite poor presenting vision, in the presence of normal perfusion near total visual recovery is possible.
