Figure 4.

Full-field ERG responses for one normal and three affected individuals homozygous for ARL3 p.(Arg99Ile) variant. Two responses (green and orange) have been superimposed for each ERG condition to show reproducibility. ERG responses of affected individuals of both families revealed moderately to severe reduction in photopic amplitudes OU, but normal scotopic, except IV:05 of family LUSG04 who had poor scotopic rod responses but normal scotopic combined responses OU (possibly insufficient dark adaptation time) and IV:03 of family LUSG03.
