vision/eye
• at 1 month of age, photopic flash electroretinographs (ERGs) show an elevated stimulus intensity threshold and a decrease in amplitude of b-waves with the prolongation of implicit time
• at 1 month of age, photopic flicker ERGs are unrecordable
• however, overall structure and retinal layer thickness is normal up to at least 3 months of age
• at 1 month of age, scotopic flash ERGs show a loss of a-waves, an elevated stimulus intensity threshold, and a severe reduction in b-wave amplitudes
