Spectrum of ophthalmic findings in Lassa fever (Lassa fever) survivors.
(A) A Lassa fever survivor with a history of a penetrating corneal injury shows uveal prolapse nasally, traumatic cataract and focal posterior synechiae temporally. (B) Another Lassa fever survivor shows macular chorioretinal scar and smaller satellite lesions temporal to the nerve. The visual acuity was 20/200. (C) One Lassa fever survivor shows multifocal scars varying from 100–200 microns within the superotemporal arcade (yellow arrows) but the fovea is spared.

Visual acuity impairment observed in Lassa fever survivors.
Fig 2.
Scatter plot of logMAR visual acuity with medians represented by horizontal bars.
Lassa fever survivors with any eye disease showed worse visual acuity than those patients with normal eye examination (p<0.0001). Eyes with anterior segment or posterior segment also showed worse visual acuity when compared to those without disease (p<0.0001 for anterior segment comparison and p<0.013 for posterior segment disease).
