Introduction: This study aimed to reveal whether retinal nerve fiber layer (RNFL), ganglion cell layer (GCL) inner plexiform layer, and choroidal layer (CL) thicknesses differed in patients with migraine. Optical coherence tomography (OCT) was used to measure these neurovascular structural changes and determine the relationship between these structures and cranial white matter hyperintensities (WMHs). Methods: This retrospective comparative registry study included a total of 155 individuals aged 18-55 (mean, 33.50 +/- 8.34), consisting of 110 migraine patients and 45 healthy controls. Results: RNFLs were thinner in the migraine group than the control group but not to a statistically significant degree. However, in both eyes, peripapillary RNLF thickness in some specific quadrants was found to be significantly thinner in the patient group than the control group. GCLs were significantly thinner in the migraine group than the control group. CLs were significantly thicker in the migraine group than in the control group. There was no significant difference between the OCT parameters of patients with and without WMH. An inverse correlation was found between disease duration and CL thickness. CLs were significantly thicker in patients in attack periods than those in attack-free periods. There was no significant difference between the OCT parameters of the migraine with aura and migraine without aura subgroups. Discussion/Conclusions: Retinal neural and vascular structures might be affected in migraine sufferers, including those in subgroups. Rebound vasodilation may cause alterations in CL thickness during a migraine attack. Factors other than hypoperfusion may contribute to the pathophysiology responsible for the formation of WMH.
