10 Causes of Nystagmus
Reviewed: Dr. Gromatzky
Cause #5: Tullio Phenomenon
Tullio phenomenon was first described in 1929 by an Italian biologist. He discovered that the associated symptoms include dizziness, nausea, vertigo, and nystagmus. It is usually caused by a fistula in the middle or inner ear causing abnormal sound synchronized pressure changes in the balance organs. It is also one of the common symptoms seen in superior canal dehiscence syndrome.
Patients who are affected often experience symptoms when there is a loud sound and may occur when there are changes in pressure such as during swallowing, nose-blowing, or straining.
