case_images: Case 1, Left eye. At admission; Color fundus picture (A) revealing a yellowish white chorioretinitis lesion with fluffy borders, measuring approximately two optic disc diameters inferior to the lower temporal vascular arcade (yellow arrow), along with a severe vitritis. Spectral-domain optical coherence tomography (SD-OCT) section passing through the chorioretinitis area (B) depicting an epiretinal membrane formation, disorganized retinal layers (blue arrow), thickened posterior hyaloid (red arrow) and focally thickened choroid (white arrow). Five months later, the appearance of recurrent chorioretinitis and severe vitritis on color fundus picture (C) and macular SD-OCT revealing the normal foveal contour together with the signs of vitritis and mild epiretinal membrane formation (D). Ten months after the diagnosis; color fundus picture demonstrating the healed chorioretinitis scar at the inferior fundus with no signs of vitritis (E). Spectral-domain OCT section transversing the healed chorioretinitis area delineating the scarring formation and chorioretinal atrophy (F).

case_images: While the right fundus appeared normal, there was a grade 6 vitritis together with a yellowish white two disc-diameter sized chorioretinal lesion at the inferior temporal fundus with fuzzy borders (Figure 1A). Thickened posterior hyaloid, epiretinal membrane (ERM) formation, disorganized retinal layers, and focally thickened choroid were noted on the spectral-domain OCT section passing through the chorioretinitis lesion (Figure 1B). Dilated fundoscopy of the left eye revealed that vitreous was very hazy and there was an active edge adjacent to the previous chorioretinitis lesion at the inferior fundus (Figure 1C). Macular spectral-domain OCT revealed a normal foveal contour, mild ERM, and hyperreflective posterior vitreous dots (Figure 1D). There was no sign of vitritis and the chorioretinitis area looked scarred in the left eye (Figure 1E). Spectral-domain OCT section passing through the lesion depicted the thinned and scarred choroid and retina (Figure 1F).

case_images: Case 2. At admission; approximately two optic disc diameters-wide yellowish white chorioretinitis areas with blurry borders on color fundus pictures of the right (A) and the left (B) eyes close to the upper temporal vascular arcade in association with a severe vitritis. Five months after the diagnosis, color fundus pictures showing the chorioretinal scars with sharp borders (C, right eye; D, left eye).

case_images: Approximately two optic disc diameter-sized yellowish white bilateral asymmetrical chorioretinitis areas with blurry borders were observed on dilated fundus examination at the upper temporal fundus with a grade 4 vitritis (Figure 2A, B). There were bilateral chorioretinal scars with well-demarcated borders with markedly diminished vitreal haze (Figure 2C, D).

case_images: Case 3, Left eye. At admission, color fundus picture (A) depicting the severe vitritis along with a yellow focal chorioretinitis area, measuring approximately two optic disc diameters, located just superotemporal to the upper temporal vascular arcade. Macular spectral-domain optical coherence tomography (SD-OCT) (B) showing the formation of epiretinal membrane (ERM) (red arrow) with normal foveal contour, a hyperreflective aggregated particle at the posterior vitreous area (blue arrow) and severe vitritis. Five months after the diagnosis; vitritis was regressed, chorioretinitis size was diminished and the borders of the chorioretinitis area had sharpened on the color fundus picture (yellow arrow) (C); while macular SD-OCT depicting the normal foveal contour and a mild formation of ERM (red arrow) (D).

case_images: The right fundus was normal whereas there was a yellow focal chorioretinitis area of two optic disc diameters size at the superior temporal fundus together with a grade 7 vitritis in the left eye (Figure 3A). Macular spectral-domain OCT depicted a vitreomacular adhesion with a normal foveal contour in OD, while there was ERM, hyperreflective aggregated particles at the posterior vitreous cortex related to severe vitritis in OS (Figure 3B). The vitreous haze lessened, and the lesion appeared atrophic with sharp borders (Figure 3C). Macular spectral-domain OCT depicted normal foveal contour in OS (Figure 3D).
