Figure 4. Electrooculography tracings. There is inter- and intrafamilial variability in the electrooculographic (EOG) findings. Individual II:2 is the only unaffected subject, with no clinical evidence of Best disease, and clearly normal EOG light rises. Both individuals II:3 and proband 2 demonstrate near-normal EOG light rises, which is atypical for Best disease.
