Summary
Migraine patients on medication accurately perceive visual verticality during headache-free periods. Subjective visual vertical (SVV) testing shows no significant difference compared to controls, even with motion sickness.
Area of Science:
- Neuroscience
- Ophthalmology
- Vestibular System
Background:
- Migraine is a complex neurological disorder.
- Otolith function is crucial for spatial orientation.
- Subjective visual vertical (SVV) assesses otolith-mediated perception.
Purpose of the Study:
- To investigate otolith function in migraine patients.
- To measure static subjective visual vertical (SVV) in migraineurs.
- To compare SVV in migraine patients and controls, with and without kinetosis.
Main Methods:
- Forty-seven migraine patients and 96 controls participated.
- Kinetosis was identified via questionnaire.
- SVV was measured using an infrared line adjustment in a dark room with head stabilization.
Main Results:
- Migraine patients showed no significant SVV deviation compared to controls.
- Aura presence did not impact SVV results.
- Dizziness, non-specific vertigo, or kinetosis did not significantly influence SVV.
Conclusions:
- Migraine patients on prophylactic medication maintain normal visual verticality perception when headache-free.
- Abnormal SVV in a headache-free migraine patient is unlikely due to migraine itself.
- Otolith function appears preserved in migraine patients during interictal periods.

Equilibrium and Balance
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
Depth Perception and Spatial Vision
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.
