Fluorescein angiography (FA) and indocyanine green angiography (ICGA) of acute syphilitic posterior placoid chorioretinitis in the right eye at presentation. (a) Early frame of FA shows hypofluorescence (yellow arrowhead) of the placoid lesion which appears hyperfluorescent in the late frames (b). (c), (d) ICGA shows hypocianescence of the placoid lesion (green arrowhead) throughout the whole examination.

Colour fundus photograph (CFP) and fundus autofluorescence (FAF) changes of acute syphilitic posterior placoid chorioretinitis in the right eye over time. (a) CFP shows a yellow placoid lesion (white arrowhead) at the posterior pole which gradually fades 1 week after presentation (b) and 2 weeks after presentation (c). FAF shows increased AF in correspondence of the placoid lesion at presentation (d) with gradual normalisazion of the AF 1 week after presentation (e) and 2 weeks after presentation (f).

MMI revealed spontaneous improvement of the placoid lesion (Figure 2 (Fig. 2), Figure 3 (Fig. 3)).
(a) Spectral domain optical coherence tomography (SD-OCT) scan of the right eye at presentation shows disruption of the ellipsoid zone (white asterisks), nodular thickening of the retinal pigment epithelium (yellow arowheads) and punctate hyperreflectivity in the inner choroid (white arrows). SD-OCT scan 1 week after presentation (b) and 2 weeks after presentation (c) show gradual recovery of the ellipsoid zone and retinal pigment epithelium.
