[Nystagmus and torticollis in albinism (author's transl)]. 1980

H F Piper

Two pairs of albinotic brothers, a severely myopic albino and an aged albinotic woman patient were examined; visual acuity was 0.2. In the nystagmogram there were varied rhythmic wave-forms with 1) oscillations of high frequency; 2) slow arrhythmic movements; 3) deviation tendencies with a fast nystagmus component. In three cases the better eye was used in adduction (latent nystagmus), in another in abduction (alternating nystagmus), and in two cases the direction of the jerks changed in accordance with the intended range of vision. The head was turned to the side of the fast component by motoric control or moved quickly, synchronized with the nystagmus. Another two patients presented with an atypical form of head-tilting, looking upward at an extreme angle or closing the weaker eye. Lowering of the eyelids and compensatory movements of the head were caused by photophobia or myopia, i.e., by sensory control.

D009759	Nystagmus, Pathologic	Involuntary movements of the eye that are divided into two types, jerk and pendular. Jerk nystagmus has a slow phase in one direction followed by a corrective fast phase in the opposite direction, and is usually caused by central or peripheral vestibular dysfunction. Pendular nystagmus features oscillations that are of equal velocity in both directions and this condition is often associated with visual loss early in life.

D004585	Electrooculography	Recording of the average amplitude of the resting potential arising between the cornea and the retina in light and dark adaptation as the eyes turn a standard distance to the right and the left. The increase in potential with light adaptation is used to evaluate the condition of the retinal pigment epithelium.	EOG,Electrooculograms,Electrooculogram

D000417	Albinism	General term for a number of inherited defects of amino acid metabolism in which there is a deficiency or absence of pigment in the eyes, skin, or hair.
D014103	Torticollis	A symptom, not a disease, of a twisted neck. In most instances, the head is tipped toward one side and the chin rotated toward the other. The involuntary muscle contractions in the neck region of patients with torticollis can be due to congenital defects, trauma, inflammation, tumors, and neurological or other factors.
