Relatively enhanced S cone function in the Goldmann-Favre syndrome.

Abstract excerpt

Using electrophysiologic and psychophysical tests that measure rod, midspectral, and S (blue) cone function, we studied four patients with the Goldmann-Favre syndrome, an autosomal recessive vitreoretinal degeneration. With spectral electroretinography, the predominant signal was from the S cones. With dark-adapted perimetry, all patients had severely reduced rod sensitivities and subnormal midspectral cone...
