Figure 3. Electroretinograms of the
patients affected with membrane-type frizzled-related protein, and
related oculopathy. Electroretinograms (ERGs) and pattern ERGs of
subject III-1 of family 4 (A), II-1 of family 1 (B), and
III-3 of family 2 (C) show severely decreased rod photoreceptor
function and moderately affected cone photoreceptor function. There is
a moderate decrease in macular function, as shown by the pattern ERGs.
Though similar ERG findings are seen in individual III-2 of family 2 (D),
pattern ERG is relatively well preserved, compared to normal case (E).
