Purpose: Photophobia is a debilitating clinical condition that disrupts the ability to use vision for everyday tasks in bright lighting conditions. The goal of the study is to develop a methodology to study the neural basis of photophobia and the contribution of the melanopic pathway to its etiology with differential chromatic responses by means of standard electroencephalographic recording equipment.
Methods: We introduce and validate the approach of recording wavelength-specific electroretinographic (ERG) responses from the face electrodes of the high-density whole-head electroencephalography recording system under light-adapted conditions.

Recent electrophysiologic studies have focussed attention on the X-linked adrenoleukodystrophy (ALD) and its myeloneuropathic variant. No organized studies are, however, yet available on its relatively recently described neonatal variant. We conducted electroencephalographic, electroretinographic and evoked response studies in 2 patients with neonatal ALD.

Electroretinographic and electroencephalographic studies were conducted in a 12-year-old boy with nephronophthisis, chronic hepatic fibrosis, mental retardation and tapetoretinal degeneration (Senior-Boichis syndrome). Markedly reduced ERG amplitudes and flat oscillatory potentials were found in the proband. Delayed scotopic implicit time and reduced amplitudes of the beta-wave were found in the mother's ERG.
