![]() ![]() Migraine accommodation autonomic dysfunction ocular higher order aberrations pupil size visual function. ![]() The accommodation status of the eye seems to be affected by this autonomic dysfunction. Our results suggest the presence of a subtle oculosympathetic hypofunction in patients with migraine during the ictal period compared to the interictal period. Comparing symptomatic and non-symptomatic sides in 17 migraine patients with unilateral headache, no significant difference was found in any of the measurements in both ictal and interictal periods. In addition, no ictal or interictal period measurements were statistically significantly different from the controls. No significant change was observed in HOAs during migraine attack. There was a significant increase in the accommodative response to accommodative stimulus of 1.5 to 5 D during migraine attack. The mean pupil size significantly decreased during migraine attack (5.85 ± 0.19 mm) compared with the interictal phase (6.05 ± 0.19 mm) in the patients with migraine ( p = 0.012). Patients with migraine were measured twice during the interictal phase and during migraine attack. Spherical, coma, trefoil aberration, and root mean square (RMS) of total HOAs were assessed. Accommodative responses to accommodative stimulus ranging from 0 to 5 diopters (D) in increments of 0.5 D were recorded. This is usually due to weakness of the iris dilator muscles, not to a problem with the iris constrictors. As you get older, your pupils tend to grow smaller. ![]() It’s normal for a newborn to have small pupils for up to two weeks. Measurements were performed using a Hartmann Shack aberrometer. Both newborns and older adults may have small pupils. This prospective, case-control study included 48 eyes of 24 patients with migraine and 48 eyes of 24 age and sex-matched healthy controls. To evaluate the pupil size, accommodation, and ocular higher-order aberrations (HOAs) in patients with migraine during migraine attacks and compare them with interictal period and healthy controls. ![]()
