AIM: To explore retinal microvascular changes in migraine patients using meta-analysis.METHODS: The National Library of Medicine PubMed, Embase, and Cochrane Library were searched to find relevant studies, and the search period was from the creation of database to June 2023. Two investigators independently screened the literatures, extracted data, and evaluated the quality of included studies using the NOS scale. STATA15.0 was used for Meta-analysis and publication bias evaluation, sensitivity analysis was performed for results with large heterogeneity, and the funnel plot and Egger were used to assess the publication bias of the literature.RESULTS:A total of 12 studies, including 217 patients(252 eyes)with migraine with aura(MA), 283 patients(388 eyes)with migraine without aura(MO), and 374 healthy individuals(479 eyes), were included in this Meta-analysis. Several optical coherence tomography angiography(OCTA)indicators, including foveal avascular zone(FAZ)macular or optic disc perfusion density were compared and analyzed. The Meta-analysis results showed that compared with healthy controls, patients with MA had a significant increase in FAZ area and perimeter, a significant decrease in perfusion density of the macular deep capillary plexus(mDCP)except for the fovea, and a significant decrease in perfusion density of the radial peripapillary capillaries(RPC)around the optic disc; the FAZ parameters were significantly increased in MO, while the differences in perfusion density of the macular superficial capillary plexus(mSCP), mDCP and RPC were not statistically significant, except for the perfusion density in the parafovea mDCP.CONCLUSIONS: Both MA and MO patients had an enlarged FAZ area, patients with MA had a significant decrease in mDCP perfusion density, and migraine patients had some degree of retinal ischemia. |
