Forte R; Saleh M, Aptel F, et al. - This study was undertaken to investigate the status of the cone photoreceptors using adaptive optics flood illumination ophthalmoscopy in patients with birdshot chorioretinopathy and to explore their correlation with optical coherence tomography (OCT) angiography. Researchers reviewed 17 patients with birdshot chorioretinopathy applying standard automated perimetry, color vision testing, fluorescein angiography, indocyanine green angiography, spectral domain OCT, enhanced depth imaging OCT, and adaptive optics flood illumination ophthalmoscopy (rtx1, Imagine Eyes, Orsay, France) in a 90 × 90-μm area at 1.5° temporal of the fovea and OCT angiography (Spectralis OCT2, Heidelberg Engineering, Heidelberg, Germany). This study enrolled a control group of 12 healthy patients (12 eyes) matched for age, gender, and refractive error for adaptive optics flood illumination ophthalmoscopy, spectral domain OCT, and OCT angiography. The outcomes of this research exhibit that birdshot chorioretinopathy can result in a reduction in cone density and establishment of macular vascular abnormalities even in the presence of preserved visual function.
