Purpose: To evaluate and characterize multiple evanescent white dot syndrome abnormalities with modern multimodal imaging modalities., Methods: This retrospective cohort study evaluated fundus photography, fluorescein angiography, indocyanine green angiography, optical coherence tomography, enhanced depth imaging optical coherence tomography, short-wavelength autofluorescence, and near-infrared autofluorescence., Results: Thirty-four multiple evanescent white dot syndrome patients with mean age of 28.7 years were studied (range, 14-49 years). Twenty-six patients were women, and eight were men. Initial mean visual acuity was 0.41 logMAR. Final mean visual acuity was 0.03 logMAR. Fluorescein angiography shows a variable number of mid retinal early fluorescent dots distributed in a wreathlike pattern, which correlate to fundus photography, fundus autofluorescence, and indocyanine green angiography. Indocyanine green angiography imaging shows the dots and also hypofluorescent, deeper, and larger spots, which are occasionally confluent, demonstrating a large plaque of deep retinal hypofluorescence. Optical coherence tomography imaging shows multifocal debris centered at and around the ellipsoid layer, corresponding to the location of spots seen with photography, indocyanine green angiography, and fluorescein angiography. Protrusions of the hyperreflectant material from the ellipsoid layer toward the outer nuclear layer correspond to the location of dots seen with photography, indocyanine green angiography, and fluorescein angiography., Conclusion: Multimodal imaging analysis of the retina in patients with multiple evanescent white dot syndrome shows additional features that may help in the diagnosis of the disease and in further understanding its etiology. Multiple evanescent white dot syndrome is predominantly a disease of the outer retina, centered at the ellipsoid zone, but also involving the interdigitation zone and the outer nuclear layer.

We report four eyes of three otherwise healthy young adults with rapid onset of visual symptoms, unilaterally and bilaterally, with clinical characteristics of acute fovealitis. We detail the clinical history, multimodal imaging, and electrophysiologic tests. Purpose: To describe four eyes of three patients with presumed acute fovealitis to expand the clinical variants of this recently described disorder. Method: The patients underwent a comprehensive ophthalmic examination, including multimodal imaging and electrophysiological tests. Results: Three female patients aged from 18 to 24 years presented sudden central visual disturbances in one or both eyes. The visual acuity ranged from 20/25 to 20/70 in the affected eyes. All of them showed a subtle yellowish lesion in the foveola. Fundus autofluorescence and fluorescein angiography were unremarkable. Optical coherence tomography disclosed focal disarrangement of the outer retinal layers restricted to the fovea and hyperreflective lesions above the external limiting membrane. Multifocal electroretinography responses were attenuated. The electrooculogram response was normal. All patients recovered normal visual acuity and the outer retinal layers. Conclusion: Attenuated multifocal electroretinography foveal response and normal electrooculogram are newly described clinical findings in patients with acute fovealitis. [ABSTRACT FROM AUTHOR]
