Cone Dystrophy in Patient with Homozygous RP1L1 Mutation

Figure 4

Full-field electroretinograms (ERGs). Full-field ERGs recorded from Case II-2 are shown. The dark-adapted 0.01, dark-adapted 3.0, light-adapted 3.0, and light-adapted 3.0 flicker ERGs are shown. The results of dark-adapted 0.01 and dark-adapted 3.0 ERGs show a slight reduction of the b-wave amplitudes of the right eye although the amplitudes are within normal limit of our institutional age-matched standard. The amplitudes of the b-wave of light-adapted 3.0 and light-adapted 3.0 flicker responses are markedly reduced in both eyes.
