Figure 5

Asymptomatic late retinochoroiditis in right eye detected in follow-up examination at month 37 (visual acuity 0.0) in 28-year-old woman from a presumed waterborne toxoplasmosis outbreak, Brazil. A) Fundus photograph showing focal retinal whitening with indistinct borders. B) Spectral-domain optical coherence tomography showing hyper-reflectivity, disorganization, and thickening of inner retinal layers (blue arrow), and numerous overlying hyper-reflective dots at the overlying vitreous and fusiform thickening of underlying choroid (yellow arrows). Scale bars indicate 200 µm.
