Eye Movement Changes in a Case of Oculocutaneous albinism
|
|
|
|

Abstract
|
|
|
Electronystagmography is an important method for differential diagnosis of central dizzness and peripherial dizzness. The study of eye movement is necessary for balance test.
Albinism is associated with neural anomalies including foveal hypoplasia and aberrant optic pathway projection that result in a variety of oculomotor instability. We present a 38-yearsold man with oculocutaneous albinism who had horizontal
jerk-type
nystagmus, which showed a reverse in direction by any extraneous light stimulation which was documented by electronystagmogram. The mechanism of the nystagmus in this case is uncertain. These findings in albinism have not been reported
previously,
to
our knowledge, and suggest a defect in the visual pathway system. (Korean J Otolaryngol 37 : 5, 1994)
