Figure 3

Asymptomatic retinochoroiditis in the right eye, detected in baseline examination (VA 0.0) of a 27-year-old man in a presumed waterborne toxoplasmosis outbreak, Brazil. A) Fundus photograph showing minimal vitreous haze; box indicates enlarged area on B); green arrows indicate multiple subtle and confluent gray-whitish punctate retinal infiltrates. C) Fundus fluorescein angiography. Pink arrows indicate leakage at the site of some of the punctate lesions. D) Fundus fluorescein angiography with red-free reflectance. Green line indicates site of optical coherence tomography scan. Yellow arrows indicate changes in the area of active focuses. E) Spectral-domain optical coherence tomography showing retinal thickening, and numerous overlying hyper-reflective dots. Blue arrows indicate multifocal hyper-reflectivity at the inner retinal layers. Scale bars indicate 200 µm. VA, visual acuity.
