Abstract

PURPOSE: To evaluate the relationships between retinal changes identified by optical coherence tomography in patients with migraine with aura or migraine without aura and the duration and severity of the disease, as measured by the questionnaire.
METHODS: In this cross-sectional study, 16 patients with migraine with aura and 15 patients with migraine without aura were compared with 16 age- and sex-matched controls without migraine. Retinal parameters were assessed using optical coherence tomography, and disease severity was evaluated using scores.
RESULTS: Foveal choroidal thickness was significantly reduced in migraine patients to controls (p=0.040). Negative correlations were observed between disease duration and total macular thickness (p=0.037), ganglion cell complex thickness (p=0.017), and choroidal thickness (p=0.039) in the migraine without aura Group. Additionally, scores showed an inverse correlation with peripapillary retinal nerve fiber layer thickness (p=0.027) in the migraine without aura Group.
CONCLUSION: Individuals with migraine exhibited significant choroidal thinning compared with controls. Longer disease duration was associated with reduced total macular, ganglion cell complex, and choroidal thickness, while greater migraine-related disability correlated with thinner peripapillary retinal nerve fiber layers.
