Purpose:
To describe three patients with idiopathic multifocal choroiditis (MFC) who showed foci of foveal outer retinal hyperreflectivity on optical coherence tomography.
Methods:
Retrospective review of electronic health records and multimodal imaging from three patients with MFC.
Results:
Three consecutive white patients with MFC (two male and one female) presented with unilateral foveal outer retinal hyperreflectivity in the eye with active MFC. In all cases, the lesions persisted for at least 1 month. Optical coherence tomography demonstrated finger-like projections of hyperreflectivity extending from the retinal pigment epithelium and through disrupted interdigitation and ellipsoid zones into the outer nuclear layer, with some aspects of the lesions reaching the inner limiting membrane. Visual recovery varied in the three affected eyes.
Conclusion:
Foveal outer retinal hyperreflectivity is a novel optical coherence tomography finding in eyes with active MFC. Additional studies will be required to address the prevalence and prognostic importance of foveal outer retinal hyperreflectivity.
