• Flicker fusion threshold intensities were measured as a function of flicker frequency for
patients with Best macular dystrophy having normal or near-normal Snellen visual acuity.
These data were found to differ from normal in ways that may be interpreted to be an
abnormal elevation of the foveal cone threshold, a loss of cone temporal resolution, or both.
The results led to the conclusion that Best macular dystrophy affects the neurosensory retina
even when Snellen visual acuity is normal.(Arch Ophthalmol95: 991-994, 1977)
