EFNS task force--therapy of nystagmus and oscillopsia.

چکیده
An overview of possible treatment options for oculomotor disorders that prevent clear vision is given. Downbeat nystagmus, upbeat nystagmus, seesaw nystagmus, periodic alternating nystagmus, acquired pendular nystagmus, and saccadic oscillations such as opsoclonus/ocular flutter are discussed. In addition, superior oblique myokymia and vestibular paroxysmia are reviewed. All treatment recommendations available in the literature are classified as class C only. In general, only some of the patients benefit from the treatment.

Intermittent oscillopsia in a case of congenital nystagmus. Dependence upon waveform.
Spontaneous reports of oscillopsia are rare in cases of congenital nystagmus (CN). We examined the relationship between nystagmus waveform characteristics and oscillopsia in one such case. To reduce the patient's nystagmus, she was fitted with contact lenses. We examined the effects of tactile feedback by applying local anesthetic while she wore the lenses. When she was without lenses, we provi...
متن کاملOscillopsia, retinal image stabilization and congenital nystagmus.
Most individuals with congenital nystagmus (CN) do not complain of oscillopsia (visual inconstancy) even though the amount of retinal image slip varies considerably according to gaze angle and CN waveform. We induced oscillopsia in four subjects with CN by artificially stabilizing images upon the retina under several conditions. Every subject reported oscillopsia during retinal image stabilizat...
متن کاملSensitivity to oscillatory target motion in congenital nystagmus.
Despite incessant to and fro motion of their eyes, persons with congenital nystagmus rarely report illusory motion of the visual world (oscillopsia). To determine whether insensitivity to retinal image motion prevents oscillopsia, thresholds for detecting horizontal and vertical oscillatory motion of a luminous dot target were measured in subjects with congenital idiopathic nystagmus and compar...
متن کاملThe mechanism of oscillopsia and its suppression.
We studied the mechanisms of oscillopsia suppression in subjects with infantile nystagmus syndrome, fusion maldevelopment nystagmus syndrome, and acquired nystagmus (AN). Hypothetical possibilities for perceptual stability were the following: (1) epochs of clear and stable vision during foveation periods of nystagmus waveforms; (2) cancellation by efference copy of motor output; (3) a combinati...
متن کاملThe sub-clinical see-saw nystagmus embedded in infantile nystagmus
A transient, decompensated vertical phoria in an individual with infantile nystagmus syndrome (INS) resulted in two images that oscillated vertically-a diplopic oscillopsia. Ocular motor studies during the vertical oscillopsia recreated by vertical prisms, led to the identification of a sub-clinical see-saw nystagmus (SSN), present under the prism-induced diplopic condition. Retrospective analy...
