The purpose of our study was to determine whether there are differences in each retinal layer between migraine patients and healthy subjects.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>A case-control study recruited 38 migraine patients and 38 age- and sex-matched controls. Optical coherence tomography was used to measure the thickness of the peripapillary and macular retinal nerve fiber layer (pRNFL and mRNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), and inner nuclear layer (INL).<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>The mean ages of the migraine patients and controls were 36.29 \u00b1 9.45 and 36.45 \u00b1 9.27 years, respectively. Thirty-four patients (89.48%) in both groups were female. The mean disability score was 19.63 \u00b1 20.44 (indicating severe disability). The superior-outer INL of migraine patients were thicker than controls. Thickness of the GCL at temporal-outer sector and mRNFL at the superior-outer sector of the headache-side eyes was reduced. However, the INL of the headache-side-eye showed negative correlation with the disability score. This is the first study having found thinning of the GCL and mRNFL of the headache-side eyes. The INL was also thickened in migraines but showed negative correlation with the disability score.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Increased INL thickness in migraine patients may result from inflammation. The more severe cases with a high disability score might suffered progressive retinal neuronal loss, resulting in thinner INL than less severe cases.<\/jats:p>\n<\/jats:sec>","DOI":"10.7717\/peerj.17454","type":"journal-article","created":{"date-parts":[[2024,5,27]],"date-time":"2024-05-27T08:41:01Z","timestamp":1716799261000},"page":"e17454","source":"Crossref","is-referenced-by-count":4,"title":["Migraine
