    Topography of patchy retinal whitening during acute perfused retinal vein occlusion by optical coherence tomography and adaptive optics fundus imaging
    Purpose. During perfused retinal vein occlusions, patchy retinal opacification due to acute neuronal swelling may be present. This may be difficult to document using conventional imaging techniques. Methods. Three-dimensional topography of focal retinal opacification was documented in a patient with hemiretinal vein occlusion by combining en face adaptive optics (AO) imaging with high-resolution optical coherence tomography (OCT). Results. Patchy retinal opacification in the macula was faintly visible by color fundus photography with no angiographic correlation. Adaptive optics and OCT imaging showed that these areas were located in the plexiform layers while the nerve fiber layer remained spared. During follow-up, visual ...
