| Abstrakt: | Purpose: To evaluate a patient with multiple evanescent white dot syndrome with multimodal imaging including high-resolution spectral-domain optical coherence tomography. Methods: The patient was evaluated with wide-field color and autofluorescence imaging, microperimetry, and near-infrared imaging. Spectral-domain optical coherence tomography was performed using an instrument capable of 3- μ m axial resolution, the high-resolution Heidelberg Spectralis. Results: A 28-year-old woman developed photopsias and a scotoma in the field of vision of her left eye. She had multiple whitish spots with granularity in her fovea, consistent with the diagnosis of multiple evanescent white dot syndrome. She had supportive fluorescein angiographic and autofluorescence findings. Because of the high resolution and good layer contrast, it was possible to create en face slab images of the external limiting membrane, ellipsoid zone, interdigitation zone, and retinal pigment epithelium. The external limiting membrane showed no abnormalities. There were multiple regions of decreased reflectance in the ellipsoid zone slab but even more prominent changes in the interdigitation zone. The retinal pigment epithelium showed nearly no variation in layer reflectivity. With resolution of symptoms, the color and autofluorescence images returned to normal, the defects in the ellipsoid zone almost completely resolved, and the interdigitation zone continued to show abnormalities. Conclusion: Although past studies concluded that the ellipsoid zone was the main region of involvement in multiple evanescent white dot syndrome, high-resolution spectral-domain optical coherence tomography suggests the interdigitation zone was more prominently affected in this case. |
