Effects of stimulus size and luminance on oscillopsia in congenital nystagmus [PDF]

open access: yesVision Research, 2003
Although the absence of oscillopsia is a common feature of congenital nystagmus (CN), it is occasionally noted by patients under poor viewing conditions and has been provoked in laboratory settings with stabilised images.

The mechanism of oscillopsia and its suppression

Annals of the New York Academy of Sciences, 2011
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 ...

Chewing Oscillopsia

Archives of Neurology, 1984
A 60-year-old man had a history of frontal headaches and chewing-related oscillopsia. Examination disclosed a retro-orbital epidermoid cyst that had eroded through the lateral orbital wall and under the temporalis muscle. The illusion of movement was due to mechanical displacement of the tumor mass and eye by contraction of the temporalis muscle ...

Retrobulbar botulinum toxin for treatment of oscillopsia [PDF]

open access: yesAustralian and New Zealand Journal of Ophthalmology, 1994
AbstractTwo cases are presented in which multiple episodic retrobulbar botulinum toxin injections have diminished incapacitating acquired oscillopsia and nystagmus and improved visual acuity. One transient ptosis occurred in six procedures. Improvement duration averaged approximately three months.

Oscillopsia associated with pseudoaccommodation in pseudophakia

Journal of Cataract and Refractive Surgery, 2020
Oscillopsia associated with near fixation after multifocal intraocular lens (IOL) implantation has not been fully recognized. A 46-year-old woman presented with shaking of vision in both eyes during near fixation after uneventful implantation of a single-piece multifocal posterior chamber IOL in both eyes.

Oscillopsia: causes and management

Current Opinion in Neurology, 2011
Oscillopsia is an illusion of an unstable visual world. It is associated with poor visual acuity and is a disabling and distressing condition reported by numerous patients with neurological disorders. The goal of this study is to review the recent findings in the various pathophysiological mechanisms of oscillopsia and the potential treatments ...

Radiation-induced oscillopsia in nasopharyngeal carcinoma patients

International Journal of Radiation Oncology Biology Physics, 2005
To apply a battery of audiovestibular function tests and magnetic resonance imaging (MRI) to investigate the causes of oscillopsia in nasopharyngeal carcinoma (NPC) patients after irradiation (RT).Of 300 NPC patients, 12 (4%) developed oscillopsia after RT. The mean accumulated radiation dose to the nasopharynx was 112 +/- 30 Gy. Each patient underwent

Oscillopsia and the Influence of Stress and Motivation in Fusion Maldevelopment Nystagmus Syndrome [PDF]

open access: yes, 2013
C1 - Journal Articles RefereedPURPOSE: We examined factors influencing perceptual stability in observers with fusion maldevelopment nystagmus syndrome (FMNS). In addition, we also investigated the effect of visual demand, task-related physiologic stress,

Voluntary Nystagmus Associated With Oscillopsia

Archives of Neurology, 1966
IN THE course of a routine neurological examination, we encountered a patient with voluntary nystagmus associated with oscillopsia. The fact that each phenomenon has been rarely encountered and the association of the two is even more unusual has prompted this communication.
