Common Causes of Oscillopsia

Oscillopsia is a visual disturbance where individuals perceive the environment as moving or oscillating when it is actually stationary. This condition can arise from a variety of underlying issues, particularly those related to the vestibular system, neurological conditions, and eye movement disorders. In this blog, we will explore the common causes of oscillopsia, helping you understand the potential origins of this unsettling symptom.

Vestibular Disorders

The vestibular system, located in the inner ear, plays a crucial role in maintaining balance and coordinating eye movements. When this system is compromised, it can lead to oscillopsia.

1. Vestibular Neuritis

Vestibular neuritis is an inflammation of the vestibular nerve, which sends balance and head position information from the inner ear to the brain. This condition can cause vertigo, dizziness, and oscillopsia due to the disrupted communication between the inner ear and the brain.

2. Ménière's Disease

Ménière's disease is a disorder of the inner ear that causes episodes of vertigo, hearing loss, tinnitus, and a feeling of fullness in the ear. The fluctuating inner ear pressure and fluid levels can affect the vestibular system, leading to oscillopsia during vertigo attacks.

3. Benign Paroxysmal Positional Vertigo (BPPV)

BPPV is caused by the displacement of tiny calcium crystals within the inner ear. These crystals can move into the semicircular canals, causing brief episodes of vertigo triggered by head movements. The abnormal signals sent to the brain can result in oscillopsia.

Neurological Conditions

Certain neurological conditions can affect the brain's ability to process sensory information, leading to oscillopsia.

1. Multiple Sclerosis (MS)

MS is a chronic autoimmune disease that affects the central nervous system, leading to the degradation of the myelin sheath that surrounds nerve fibers. When the nerve pathways that control eye movements are damaged, it can cause nystagmus (involuntary eye movements) and oscillopsia.

2. Stroke

A stroke can damage areas of the brain responsible for balance and eye movement control. This damage can disrupt the normal processing of visual and vestibular information, resulting in oscillopsia.

3. Migraines

Some individuals experience vestibular migraines, which can cause vertigo and oscillopsia. The exact mechanisms are not fully understood, but it is believed that abnormal neural activity during a migraine can affect the vestibular system.

Eye Movement Disorders

Disorders affecting the muscles or nerves that control eye movements can lead to oscillopsia.

1. Nystagmus

Nystagmus is a condition characterized by rapid, involuntary eye movements. These movements can be horizontal, vertical, or rotational, and can cause the visual field to appear as if it is moving. Nystagmus can be congenital or acquired due to neurological or vestibular conditions.

2. Internuclear Ophthalmoplegia (INO)

INO is a disorder caused by damage to the nerve pathways that coordinate eye movements, specifically the medial longitudinal fasciculus. This condition results in the inability to move both eyes in the same direction, leading to double vision and oscillopsia.

3. Ocular Myasthenia Gravis

Ocular myasthenia gravis is an autoimmune disorder that affects the muscles controlling eye and eyelid movements. Muscle weakness can lead to misalignment of the eyes and unstable vision, resulting in oscillopsia.

Other Contributing Factors

While vestibular disorders, neurological conditions, and eye movement disorders are the primary causes of oscillopsia, other factors can contribute to this symptom.

1. Head Injuries

Trauma to the head or neck can damage the vestibular system or the brain areas involved in visual processing, leading to oscillopsia.

2. Medications

Certain medications, especially those affecting the central nervous system, can cause side effects that include oscillopsia. Drugs used to treat epilepsy, anxiety, and depression are among those that may have such effects.

3. Alcohol and Substance Use

Excessive consumption of alcohol or the use of certain substances can impair the vestibular system and eye movements, leading to temporary or prolonged oscillopsia.


Oscillopsia is a complex symptom with multiple potential causes. Understanding these causes can help in diagnosing and treating the underlying conditions. If you or someone you know is experiencing oscillopsia, it is essential to seek medical advice for proper evaluation and management.
