“…This finding was consistent with the results of the study of Gandhi et al, but not consistent with the results of the study of Kara. 13,14 This difference can be related to differences in the techniques used for RNFL thickness measured. It should be noted that the area of the optic disc after the age of 10 is not related to the person's age.…”

Background: Headache is one of the most disturbing symptoms with common neurological signs. Variations in optic nerve perfusion quality or retinal microcirculation may end up in peripapillary retinal nerve fiber layer (RNFL) thickness in patients with migraine. The aim of this study was to investigate the retinal nerve fiber layer (RNFL) thickness in patients with migraine.Methods: This cross-sectional study was conducted by including thirty patients diagnosed with migraine and thirty normal individuals. Patients were evaluated in groups including migraine with and without aura and controls. Retinal nerve fiber layer (RNFL) thickness was measured using stratus optical coherence tomography (OCT) and then was compared in case and control groups. All data were analyzed using SPSS software version 16.Results: RNFL thickness was significantly thinner in migraine patients compared to the control group. Symmetricity of RNFL showed significantly reduction in patients with migraine compared to standard value (95% vs 68%). Comparison of NRR area between patients and standard value showed significantly reduced values (P=0.0001). Mean value of optic disc area showed significantly reduced value compared to standard value about 2.35 m2 (P=0.0001).Conclusions: This study suggests that migraine leads to a reduction in the peripapillary RNFL thickness and to thinning in choroidal structures. These findings can be explained by a chronic ischemic insult related to migraine pathogenic mechanisms.

“…It has been shown that RNFL thinning occurs at different quadrants, and there are also studies regarding the relation between migraine and retrobulbar blood flow alterations. [15][16][17][18][19][20][21] According to Kara et al, 30 the retrobulbar circulation and flow haemodynamics in the left vertebral artery may be altered in both headache and headache-free periods in migraineurs without aura. Glenn et al 31 reported a case of complicated migraine due to bilateral retinal infarction.…”

The aim of this study was to determine whether retinal nerve fibre layer (RNFL) thickness is correlated with cerebral white matter lesions (WML) in migraine patients. Forty migraine and 40 healthy subjects were included in this study. The difference in RNFL thickness between the control and a migraine group with WML and a migraine group without WML were investigated using analysis of variance (ANOVA). A Tukey post hoc test was conducted to determine from which group the difference originated. Lower RNFL thicknesses were observed in the migraine patient group where WML was detected using magnetic resonance imaging (MRI), compared with the control group and with the migraine group with no WML. Statistically significant difference was found between the three groups in terms of RNFL thickness. Although there was a statistically significant difference between the control and the migraine group with WML detected with MRI, no statistically significant difference was found in terms of RNFL thickness between the control and the migraine group with no WML related to Tukey post hoc test. Moreover, there was a statistically significant difference between migraine patients with WML and patients without WML in terms of retinal nerve fibre layer thickness. The results indicate that reduction in RNFL detected via optical coherence tomography may be related to cerebral WML in migraine patients. Further studies by neurologists and ophthalmologists are necessary to determine the clinical relevance of the relation between RNFL and cerebral WML. ARTICLE HISTORY

“…In one study by Kara et al in which Doppler ultrasound was used to demonstrate retinal vascular changes and perfusion in migraine patients, the resistance in the central retinal artery and posterior ciliary artery was found to be higher in migraine patients than in the control group (14) . In another study by Martinez et al, who compared 70 migraine patients and 53 normal individuals using OCT, the mean RNFL thickness was determined to be normal in migraine patients, but the RNFL thickness in the temporal quadrant was significantly thinner (4) .…”

Espessuras da camada de fibras nervosas retinianas, complexo de células ganglionares e coroide na enxaqueca ABSTRACTPurpose: To evaluate the thicknesses of the peripapillary retinal nerve fiber layer (RNFL), ganglion cell complex (GCL), and choroid layer using spectral domain optical coherence tomography (SD-OCT) for investigating the effects of vascular changes on the eye and optic nerve in patients who have migraine with aura. Methods: Forty-five patients who had migraine with aura (migraine group) and 45 healthy individuals (control group) were enrolled in the study. Age, gender, duration after migraine diagnosis, intraocular pressure, and axial length measurements were recorded in each case. RNFL, GCL, and choroid layer thicknesses were measured using SD-OCT in all participants. Results: The mean age was 36.1 ± 6.7 (20-45) years in the migraine group and 35.7 ± 8.6 (19-45) years in the control group. There was no significant difference in the RNFL thicknesses of the temporal and nasal quadrants (p>0.05). The RNFL thicknesses of the superior and inferior quadrants were significantly lower in the migraine group compared with those in the control group (p=0.001, p<0.01, respectively). Measurements for the superior and inferior GCL were not significantly different between the groups (p>0.05). Subfoveal, temporal, and nasal choroidal thickness measurements at 500 µm, 1000 µm, and 1500 µm were significantly lower in the migraine group than in the control group (p=0.001; p<0.01, respectively). Conclusions:Compared with the controls, the RNFL and choroid layer were determined to be thinner in patients who had chronic migraine with aura. de 36,1 ± 6,7 (20-45) anos no grupo enxaqueca e 35,7 ± 8,6 (19-45) Keywords

Color Doppler sonography of orbital and vertebral arteries in migraineurs without aura

Abstract: The retrobulbar circulation and flow hemodynamics in the left VA may be altered in both headache and headache-free periods in migraineurs without aura. The differences found between migraineurs and control subjects may implicate autonomic dysfunction in migraineurs.
