Neuropediatrics . 2003 Sep; 34(4):219-23. PMID: 12973665
Congenital nystagmus is a rare condition mainly characterised by rhythmic, conjugate, and horizontal oscillations of both eyes that persist in the vertical gaze. This disorder is usually noticed in the...

Strabismus . 2001 Nov; 9(3):143-63. PMID: 11704879
Purpose: The purpose of the present study was to accurately document the oculomotor misalignments and instabilities associated with the non-decussating retinal-fugal fiber syndrome, a rare inborn, isolated, achiasmatic condition. To...

Victor J, Apkarian P, Hirsch J, Conte M, Packard M, Relkin N, et al.
Cereb Cortex . 2000 Jan; 10(1):2-22. PMID: 10639391
Functional neuroimaging, psychophysical and electrophysiological investigations were performed in a patient with non-decussating retinal-fugal fibre syndrome, an inborn achiasmatic state in which the retinal projections of each eye map entirely...

van t Ent D, Apkarian P
Clin Neurophysiol . 1999 Jul; 110(6):1058-72. PMID: 10402093
Objective: To study cortical potentials associated with suppression of intended motoric actions. Methods: Electro-encephalographic activity was recorded in a Go/NoGo reaction time paradigm. Subjects viewed computer-generated pacing stimuli, which provided...

Electroencephalogr Clin Neurophysiol . 1999 Jan; 107(4):263-76. PMID: 9872444
To study hemispheric lateralization of cortical potentials associated with motoric and non-motoric function, cortical activity was recorded accompanying either finger extension or saccadic eye movements in a contingent negative variation...

Bour L, Apkarian P
Invest Ophthalmol Vis Sci . 1996 Nov; 37(12):2475-84. PMID: 8933764
Purpose: Contrast sensitivity functions (CSFs) were measured under various optical conditions in healthy observers together with CSFs from selected patients. Threshold increases across the spatial frequency range were compared with...

In the present overview, practical application of the visual evoked potential (VEP) in paediatric neuro-ophthalmology is described across a wide range of ophthalmogenetic disorders, including albinism, Pelizaeus-Merzbacher disease and spastic...
