noted that the Veteran still reported occasional "shades" coming down as those could possibly be either Hollenhorst plaques traversing the retinal artery or transient decompensation of the parieto-occipital territory as described elsewhere due to the effects of chronic stroke.

The examiner reported that no bilateral visual field deficits (which would be the expected visual field deficit corresponding to a stroke) were noted via screening testing as part of that examination.
