Spectrum of Imaging Characteristics of Birdshot Chorioretinopathy.

Abstract

Birdshot chorioretinopathy (BSCR) is a bilateral, chronic posterior uveitis with characteristic clinical and imaging findings. Multimodal imaging including optical coherence tomography, fluorescein, and indocyanine green angiography is useful in diagnosis, as well as monitoring disease activity. Cystoid macular edema, choroidal thickening and infiltration, ellipsoid loss, and vasculitis are important imaging markers for disease activity. The purpose of this case series is to discuss the spectrum of disease presentations and highlight both common and atypical imaging characteristics of BSCR that may provide clinical insight to allow for better identification and treatment of disease.
