BACKGROUND: Migraine is a neurovascular disease and has been reported as a risk factor for ocular vascular complications. Our study aimed to compare the retinal vessel density and perfusion density between migraine patients and healthy subjects by optical coherence tomography angiography (OCTA).
METHODS: In this prospective study, 23 patients with migraine with aura (MWA) and 31 patients with migraine without aura (MWOA), and 32 age- and gender-matched healthy controls (HC) were enrolled. The vessel density (VD) and perfusion density (PD) were evaluated in a 6 × 6 mm scan of the macula and optic nerve head (ONH) with the Cirrus HD-OCT 5000 device. The measurement area is divided into three areas: center (c), inner ring (ir), outer ring (or) (with diameters of 1, 3, and 6 mm respectively), and nine subfields, according to the Early Treatment Retinopathy Study grid.
RESULTS: The macular cVD, cPD, and temporal orVD in MWA and MWOA groups were significantly reduced than those of HC. On optic nerve head OCTA, patients with MWA had decreased cVD, average irVD, inferior irVD, and temporal orVD compared with HCs while MWOA had reduced cVD than HC group. In addition, PD was not significantly different among MWA, MWOA, and HC groups in any measure in the optic nerve head. The Migraine Disability Assessment Score (MIDAS) and attack frequency were significantly inversely correlated with cVD, cPD, irVD, and irPD of macula and ONH.
CONCLUSIONS: Vessel and perfusion density of macula were reduced in both MWA and MWOA. Vessel density, but not perfusion density of ONH was decreased in MWA. The migraine severity and attack frequency were significantly inversely correlated with vessel and perfusion density of macula and ONH.
