The ophthalmoscope, absolutely, has been precious in assessing optic disc lesions, yet couldn't provide us informa­ tion at the circulate of the attention and optic disc "in vivo".

The electro-oculogram was recorded in the standard manner, described by ARDEN et al. [16], during 12 minutes of dark adaptation, followed by 12 minutes of light adaptation (luminance = 1,700 milli-Iamberts). ). The recording system incorporated a computer of average transients. The electroretinograms were measured in millimicrons, the maximum b-wave being measured from the trough of the a-wave to the peak of the b-wave. Flicker Fusion Frequency of the electroretinogram was recorded to determine whether the response was scotopic (20 Hertz or less), photopic (60 Hertz) or mixed (40 Hertz).
