Oscillopsia
Oscillopsia
Oscillopsia (/ɒˌsɪləʊˈɒpsɪə/) is a visual disturbance in which objects in the visual field appear to oscillate. The severity of the effect may range from a mild blurring to rapid and periodic jumping. The term is derived from the Greek words "oscillo" meaning 'to swing' and "opsia" meaning 'view'.
Causes
Oscillopsia is most commonly caused by conditions that affect the vestibular system, which is responsible for maintaining balance, posture, and the body's orientation in space. This includes conditions such as vestibular neuritis, Meniere's disease, and vestibular migraine. It can also be caused by rapid eye movement during nystagmus.
Symptoms
The primary symptom of oscillopsia is a perception that the surrounding environment is constantly in motion. This can lead to difficulty focusing on objects, problems with depth perception, and balance issues. Other symptoms may include dizziness, nausea, and difficulty reading or seeing in low light.
Treatment
Treatment for oscillopsia typically involves treating the underlying cause. This may include medications, physical therapy, or surgery. In some cases, special glasses or contact lenses may be used to reduce the symptoms.
