En-Face Optical Coherence Tomography of Acute Syphilitic Posterior Placoid Chorioretinopathy.

PURPOSE

To report a unique case series of acute syphilitic posterior placoid chorioretinopathy (ASPPC) correlating en-face optical coherence tomography (OCT) with standard imaging modalities.

METHODS

In this retrospective case series, multimodal imaging was performed in three ASPPC patients at the time of disease presentation.

RESULTS

Clinical and laboratory findings were consistent with the diagnosis of ASPPC. In all the study patients, multiple hyperreflective dot-like lesions distributed in the macular area and observed with en-face OCT at the level of retinal pigment epithelium (RPE) corresponded to the nodular RPE elevations on cross-sectional OCT and to the hyperautofluorescent spots on fundus autofluorescence. In addition, the cross-sectional OCT scans showed disorganization of the outer retinal bands and punctate choroidal hyperreflectivity.

CONCLUSION

By combining en-face OCT with multimodal imaging analysis, we propose that a primary inflammation at the level of the choroid may be the pathogenic mechanism for the occurrence of outer retinal band abnormalities.
