“…That is, the increment threshold is defined by solving the following equation for ΔC via computer iteration: (2) We arbitrarily chose θ = 5, but this value again does not affect results as long as θ is much less than R Max . Increment thresholds were calculated in this manner for both unadapted and adapted conditions and the ratio taken to compute threshold elevations.…”

“…However, interictal visual discomfort has been reported to be linked not only to light intensity, but also to specific spatial and temporal properties of the visual input. In particular, spatial and temporal frequencies close to the peak of the human contrast sensitivity function (3-5 c/deg stripes and 10-20 Hz flicker) are most aversive (2)(3)(4)(5). Flicker is particularly bothersome to individuals with migraine.…”

“…In addition, people show more aversion to striped patterns if they are headache sufferers particularly if the headaches are migraines. Marcus and Soso (1989) showed that when viewing epileptogenic striped patterns, 82% of migraine suffers demonstrated aversion whist only 18% of a control group did so. There was no difference between migraine with and without aura.…”

Migraine is a common, chronic, multi-factorial, neuro-vascular disorder typically characterised by recurrent attacks of unilateral, pulsating headache and autonomic nervous system dysfunction. Migraine may additionally be associated with aura; those focal neurological symptoms that may precede or sometimes accompany the headache. This review describes the optometric aspects of migraine headache. There have been claims of a relationship between migraine headaches and errors of refraction, binocular vision anomalies, pupil anomalies, visual field changes and pattern glare. The quality of the evidence for a relationship between errors of refraction and binocular vision and migraine is poor. The quality of the evidence to suggest a relationship between migraine headache and pupil anomalies, visual field defects and pattern glare is stronger. In particular the link between migraine headache and pattern glare is striking. The therapeutic use of precision-tinted spectacles to reduce pattern glare (visual stress) and to help some migraine sufferers is described.

“…Hyperexcitability has been inferred from an over-response to sensory stimuli; for example, migraineurs show more signs of aversion to achromatic gratings than control groups (3,4).…”

Cortical hyperexcitability in migraine and aversion to patterns

et al. 2012

Background-Patients with migraine are averse to certain visual stimuli, such as flicker and striped patterns that evoke paroxysmal EEG activity in patients with photosensitive epilepsy. Migraineurs demonstrate a hyper-responsiveness to such stimuli, and there is debate as to whether the aversion and hyper-responsiveness are due to a hyperexcitability of the cortex similar to that in patients with photosensitive epilepsy. In these patients grating patterns with certain spatial characteristics can be epileptogenic, depending critically on their movement. If the contours of the grating drift continually, the grating is not epileptogenic, but if the contours are static or if their direction is repeatedly and rapidly reversed so as to vibrate, the grating then becomes highly epileptogenic.
