Abstract
PURPOSE To evaluate the possible effects of migraine on retinal nerve fibre layer (RNFL), ganglion cell-inner plexiform layer (GC-IPL), macular thickness and retinal arteriolar and venular diameters (CRAE, CRVE) in a population-based birth cohort. METHODS 375 migraineurs and 1489 healthy controls were included in this cross-sectional cohort study. RNFL, GC-IPL and macular thickness parameters were measured by spectral domain optical coherence tomography (OCT), and vascular parameters were measured from fundus photographs. Migraine was determined by a questionnaire and specific features were selected as covariates (gender, smoking status, systolic blood pressure, refraction and diabetes). RESULTS There were no statistically significant differences between healthy controls and migraineurs in average RNFL (p = 0.123), macular (p = 0.488) or GC-IPL (p = 0.437) thickness. Migraine did not have a significant effect on any of the macular or GC-IPL subfields. For RNFL subfields, only temporal inferior was borderline significantly increased in migraineurs (p = 0.039) in adjusted results. No statistically significant differences were found between study groups on retinal vascular calibres CRAE (p = 0.879), CRVE (p = 0.145) or AVR (p = 0.259). GC-IPL thickness was found to be positively correlated with CRAE and CRVE in both study groups as GC-IPL thickness increased together with the increase in CRAE and CRVE (p-trend < 0.001 in both), and a similar trend was detected with central macular subfield thickness and systolic (p-trend < 0.001) and diastolic (p-trend = 0.010) blood pressure, but only in the control group. CONCLUSION There were no remarkable differences between migraineurs and healthy controls in retinal vascular or structural parameters in our study.

Abstract
Background Activation of the trigeminal vascular system in migraine releases vasoactive neurotransmitters, causing abnormal vasoconstriction, which may affect the ocular system, leading to retinal damage. The purpose of our study was to determine whether there are differences in each retinal layer between migraine patients and healthy subjects. Methods 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). Results The mean ages of the migraine patients and controls were 36.29 ± 9.45 and 36.45 ± 9.27 years, respectively. Thirty-four patients (89.48%) in both groups were female. The mean disability score was 19.63 ± 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. Conclusions 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.

Abstract
BACKGROUND Migraine is characterized by recurrent episodes of unilateral, pulsating headaches. At the cerebral and ocular levels, it is recognized that the vascular narrowing and loss of blood flow are transient; however, the chronic nature of migraine may result in long-term functional and structural changes in these structures. It could result in axonal loss and an alteration in the thickness of the retinal nerve fiber layers (RNFL). This study aimed to measure the RNFL thickness, which provides a useful indication of the state of the axons and the loss of ganglion cells in migraine patients, and to find out if RNFL thickness and the clinical features of migraine are correlated. MATERIALS AND METHODS Sixty patients with migraine and 60 age-gender-matched controls were recruited. A complete neurological and ophthalmological examination was performed, and spectral-domain optical coherence tomography (SD-OCT) was done to measure RNFL. RESULTS All quadrants of the retina on both sides showed non-statistically significant differences in RNFL thickness between migraine patients and controls (p-value >0.05). Furthermore, in all retinal quadrants on both sides, there was no statistically significant difference in RNFL thickness between migraine patients with aura and those without aura (p-value >0.05). Significant correlations were found between the duration of migraine disease and the superior RNFL thickness of both eyes, as well as the inferior RNFL in the right eye. There was also a significant correlation between the headache attack duration and RNFL thickness of the superior retina (p<0.05), Conclusion: Our key finding was that when comparing migraine patients to controls, RNFL thickness did not significantly change; however, the duration of migraine disease did significantly affect RNFL thickness.

Abstract
Migraine is one of the world's most debilitating disorders, and it has recently been shown that changes in the retina can be a potential biomarker for the disease. These changes can be detected by optical coherence tomography (OCT), which measures retinal thickness, and optical coherence tomography angiography (OCTA), which measures vessel density. We searched the databases Google Scholar, ProQuest, Scopus, and Web of Science for studies in English using OCT and OCTA in migraineurs, using the search terms "optical coherence tomography," "OCT," "optical coherence tomography angiography," "OCTA" and "migraine." We found 73 primary studies, 11 reviews, and 8 meta-analyses pertaining to OCT and OCTA findings in migraineurs. They showed that migraineurs had reduced retinal thickness (via OCT), retinal vessel density, and greater foveal avascular zone area (via OCTA) than controls. OCTA changes reflect a perfusion compromise occurring in migraineurs as opposed to in healthy controls. OCT and OCTA deficits were worse in migraine-with-aura and chronic migraine than in migraine-without-aura and episodic migraine. Certain areas of the eye, such as the fovea, may be more vulnerable to these perfusion changes than other parts. Direct comparison between study findings is difficult because of the heterogeneity between the studies in terms of both methodology and analysis. Moreover, as almost all case-control studies were cross-sectional, more longitudinal cohort studies are needed to determine cause and effect between migraine pathophysiology and OCT/OCTA findings. Current evidence suggests both OCT and OCTA may serve as retinal markers for migraineurs, and further research in this field will hopefully enable us to better understand the vascular changes associated with migraine, perhaps also providing a new diagnostic and therapeutic biomarker.

Abstract
OBJECTIVE To evaluate and compare choroidal thickness (CT) between patients with Meniere's disease (MD) and a control group. METHODS This case-control analytical study was conducted on 37 subjects with MD and 37 healthy subjects. Subfoveal CT (SCT), large choroidal vessel (LCV) layer thickness, and mean subfoveal LCV thickness/mean SCT ratio were measured using enhanced-depth imaging optical coherence tomography (EDI-OCT) in the eyes on the MD side (ipsilateral), the contralateral eyes, and the control group. RESULTS A statistically significant difference was observed in the mean SCT values between the ipsilateral and control groups after adjustment for age, sex, and migraine (p = 0.04). Moreover, there was a statistically significant difference between the mean subfoveal LCV thickness values and the mean subfoveal LCV thickness/mean SCT ratio between the ipsilateral and control groups (p = 0.006, and p < 0.001, respectively). Patients with a duration of disease over three years had a greater mean subfoveal LCV thickness/mean SCT ratio (67.35 ± 11.56 and 60.66 ± 11.27, respectively), which was statistically insignificant (p = 0.08). CONCLUSION We found a thicker choroid and Haller layer, and a greater subfoveal LCV thickness/SCT ratio on the MD side compared to the controls. Furthermore, patients with a greater duration of disease had a lower subfoveal LCV thickness/SCT ratio. These findings may reflect the role of the trigeminal vascular system (TVS) and neurovascular pathophysiology in MD patients. More extensive studies are required to reach more definitive conclusions about the association between CT and MD. LEVEL OF EVIDENCE 4 Laryngoscope, 134:1889-1893, 2024.

Abstract
OBJECTIVE To determine if there are changes in structure and function of the retinal vasculature during and between migraine attacks using optical coherence tomography angiography (OCTA). BACKGROUND Migraine attacks commonly include visual symptoms, but the potential role of the retina in these symptoms is not well understood. OCTA is a rapid, non-invasive imaging technique that is used to visualize the retinal microvasculature with high spatial resolution in a clinical setting. In this study we used OCTA to quantify different features of the retinal vasculature in patients with migraine during and between attacks, as well as in healthy controls (HCs). METHODS We performed a prospective cohort study of 37 patients with migraine with aura (MA) (median [interquartile range, IQR] age of 37 [14] years, 86% female) and 30 with migraine without aura (MO) (median [IQR] age of 37 [17] years, 77% female) and 20 HCs (median [IQR] age of 35 [7] years, 50% female). Macular OCTA scans were obtained for all participants for the interictal analysis. In 12 MA and eight MO, scans were captured both during and outside of migraine attacks and five HCs had initial and repeat scans. In addition to analyzing the morphology of the foveal avascular zone, we calculated the vessel flux index (VFI), which is an indicator of retinal perfusion and conventional metrics (such as vessel area density) in the foveal and parafoveal regions. RESULTS There was a significant difference in the parafoveal VFI in the ictal state between the groups (p = 0.009). During migraine attacks there was a significant reduction in the parafoveal region VFI in MA (-7%, 95% confidence interval [CI] -10% to -4%; p = 0.006) and MO (-7%, 95% CI -10% to -3%; p = 0.016) from their interictal baseline as compared to the change between repeat scans in HCs (2%, 95% CI -3% to 7%). Interictally, there was a mean (standard deviation [SD]) 13% (10%) (p = 0.003) lower blood perfusion in the MA group as compared to the MO group in the foveal region (mean [SD] 0.093 [0.023] vs. 0.107 [0.021], p = 0.003). Interictal analysis also revealed higher circularity in the superficial foveal avascular zone in the MA group compared with the MO group (mean [SD] 0.686 [0.088] vs. 0.629 [0.120], p = 0.004). In addition, interictal analysis of the patients with MA or MO and unilateral headache showed increased retinal vascular parameters consistent with greater perfusion in the eye ipsilateral to the side of the pain as compared with the contralateral eye. CONCLUSIONS These results indicate that perfusion is reduced in MA and MO in the parafoveal retina during the ictal period. Interictally, the foveal retina in MA has reduced perfusion when compared to the foveal retina in MO. Patients with unilateral headache showed interictal asymmetry of retinal perfusion between eyes. These results indicate that changes in retinal perfusion could be a part of migraine pathophysiology, and that distinct retinal vascular signatures identified with OCTA could represent biomarkers for migraine.

Abstract
Introduction Headache is a widely prevalent illness that negatively impacts people's lives, leaving them functionally incapable of performing regular everyday tasks. The global burden of headache is 40%, of which migraine accounts for 47%. Objective This study aims to determine the frequency of migraine among medical students of Lahore and its characteristics, associated triggers, and relievers among medical students. Methodology A cross-sectional study was conducted in medical colleges after obtaining ethical approval. Migraine was diagnosed using the criteria provided in the International Classification of Headache Disorders, Third Edition (ICHD-3), and data on triggers, relief, and demographics were collected. The information is analyzed using SPSS 22. Result The data were collected from 522 medical students. The average age of the students was 21.3 ± 2.0 SD (in years). About 146 (28.0%) of the medical students have migraine according to ICHD-3 criteria and were diagnosed initially. Gender was insignificantly associated with migraine (P-value=0.32). Students with psoriasis, hypertension, and polycystic ovarian syndrome were statistically significantly related to migraines with a P-value=0.002. Dehydration is the most frequent aggravator, and adequate sleep is the most frequent reliever of migraine. Conclusion The findings show a high frequency of migraine. They are similar in both genders, depicting that stressful lifestyles, inadequate sleep patterns, and bizarre dietary habits make them more prone to migraine episodes. So, further, detailed studies should be done on evaluating triggers and relievers of migraine and their interrelations with migraine so we can focus on preventive strategies, diagnosis, and treatment of migraine.

Abstract
BACKGROUND Migraine is a neurovascular disease that can cause ocular and systemic ischemic damage. Despite from aura, a limited number of studies have considered the effect of the chronic migraine in cases without aura. Our aim was to evaluate the differences in the retinal and optic disk microvasculature among episodic and chronic migraine cases without aura using optical coherence tomography angiography (OCTA) imaging. METHODS 45 cases with migraine, and 25 control subjects were included in this prospective, cross-sectional study. OCTA was performed at 3 × 3 mm and 6 × 6 mm of the macula and at 4.5 × 4.5 mm of the optic disk. Retinal nerve fiber layer (RNFL) thickness, ganglion cell complex thickness, and vessel densities of the optic nerve and macula were compared among the three groups: a control group, an episodic migraine without aura (EMWOA) group, and a chronic migraine without aura (CMWOA) group. RESULTS In EMWOA group, circumpapillary vascular density (cpVD) was not decreased significantly in any quadrants (all, p>0.05). Compared to the control group, CMWOA group had significantly lower RNFL thickness in superior-temporal quadrants (p = 0.002 and 0.006, respectively), while cpVD differed only in the temporal quadrant and temporal inferior sector (p = 0.002 and p = 0.009, respectively). CONCLUSIONS Temporal peripapillary perfusion is valuable in the follow-up of chronic migraine cases. Longitudinal studies are needed to determine the place of OCTA in the follow-up of migraine.

Abstract
BACKGROUND Retinal migraine is a diagnosis of exclusion and is characterized by repeated episodes of transient monocular blindness associated with migraine. We report a case of systemic lupus erythematosus with acute episodes mimicking retinal migraines. CASE REPORT A 46-year-old woman with a history of migraine with aura since her 20s and Evans syndrome presented with episodic transient monocular blindness. Retinal migraine was considered as the cause, and migraine prophylaxis initially reduced its frequency. After 5 months, the frequency increased, with chilblain-like lupus lesions on her extremities. Laboratory testing revealed lymphopenia and hypocomplementemia, fulfilling the diagnostic criteria for systemic lupus erythematosus, which may have caused Evans syndrome and transient monocular blindness, mimicking retinal migraines. After intravenous methylprednisolone and rituximab therapy, the transient monocular blindness episodes did not recur. CONCLUSION Given the clinical presentation, systemic lupus erythematosus should be considered as a cause of transient monocular blindness and should be distinguished from retinal migraine.

Abstract
Background Migraine is a common and distressing neurological condition characterised by recurrent throbbing headaches, nausea and heightened sensitivity to light and sound. Accumulating evidence suggests that cerebral arteries dilate during migraine, causing distal microvessels to constrict, which could activate nociceptors and cause onset of headache pain. If so, preventing or attenuating chronic microvascular constriction, and promoting a dilatory phenotype, may reduce frequency and/or severity of migraines. The primary aim of the L-Arginine and Aged Garlic Extract (LARGE) trial is to investigate whether oral treatment with dietary nutraceuticals, L-arginine and aged garlic extract (AGE), both systemic vasodilatory agents, will alleviate migraine frequency, duration and severity in adults with chronic frequent episodic migraines. Methods The study is a randomised double-blind placebo-controlled phase-II single-site clinical trial conducted in Perth, Australia. The target sample is to recruit 240 participants diagnosed with chronic frequent episodic migraines between 18 and 80 years of age. Participants will be randomised to one of four treatment groups for 14 weeks (placebo induction for 2 weeks, followed by 12 weeks on one of the respective treatment arms): placebo, L-arginine, AGE, or a combination of L-arginine and AGE. The doses of L-arginine and AGE are 1.5 g and 1 g daily, respectively. The primary outcome is to assess migraine response using change in migraine frequency and intensity between baseline and 12 weeks. Secondary outcomes include the impact of L-arginine and/or AGE on photosensitivity, retinal vessel changes, and blood biomarker concentrations of vascular tone, following a 12-week intervention. Discussion The protocol describes the oral administration of 2 nutraceutical-based interventions as possible prophylactic treatments for chronic frequent episodic migraines, with potential for direct clinical translation of outcomes. Potential limitations of the study include the fixed-dose design of each treatment arm and that in vivo neuroimaging methods, such as magnetic resonance imaging (MRI), will not be conducted to determine putative cerebro-vasodilatory changes to coincide with the outcome measures. Dose-response studies may be indicated. Trial registration The trial was retrospectively registered with the Australian New Zealand Clinical Trials Registry ACTRN12621001476820 (Universal Trial Number: U1111-1268-1117) on 04/08/2021. This is protocol version 1, submitted on 25/11/2022. Supplementary Information The online version contains supplementary material available at 10.1186/s12883-023-03149-y.

Abstract
Recent developments in high-resolution optical coherence tomography allow evaluation of even the slightest changes of choroidal thickness in various disorders, including migraine. In this review, we analyze the choroidal thickness measurements reported in various studies that compare results between migraineurs and healthy individuals. We searched PubMed, Scopus, and EMBASE to identify relevant literature reporting choroidal thickness in the migraineurs' different macular regions compared with healthy controls. A fixed-effects or random-effects model was applied for the meta-analysis based on the heterogeneity level. Moreover, subgroup analyses, meta-regression, publication bias, and quality assessment were also performed. We identified ten studies involving 580 migraineurs (173 with aura, 128 without aura, and 279 without specification for the presence of aura) and 407 healthy controls to be included in this meta-analysis. Results indicated that average choroidal thickness was significantly decreased in the migraine cases (SMD, -1.28; 95% CI, -2.47 to -0.08; P = 0.04) compared to healthy individuals. Furthermore, both with aura (SMD, -1.16; 95% CI, -1.39 to -0.92; P < 0.0001) and without aura migraine patients (SMD, -0.81; 95% CI, -1.28 to -0.34; P < 0.001) had significantly thinner subfoveal choroid compared to healthy controls. Moreover, subfoveal choroidal thickness in the migraineurs with aura was significantly lower than those without aura (SMD, -0.45; 95% CI, -0.84 to -0.05; P = 0.03). The alterations in choroidal thickness, suggestive of migraine's neurovascular pathophysiology, were tentatively confirmed by this study's findings. Further longitudinal studies with more diverse settings are required to derive more definitive conclusions.

Diagnostics (Basel) 2022; 13:diagnostics13010005. [PMID: 36611297 PMCID: PMC9818823 DOI: 10.3390/diagnostics13010005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 11/24/2022] [Accepted: 11/29/2022] [Indexed: 12/24/2022] Open
Abstract
The purpose of this study is to determine the possible alterations that may occur in the thickness of the retinal nerve fibre layer (RNFL), ganglion cell layer (GCL), and macular thickness in patients with chronic migraines compared with healthy controls. Hence, we examined some of the possibilities that are offered by optical coherence tomography (OCT) in order to study different neurological diseases and to study its application, in this case, how it may be applied to patients with chronic migraines. This was an observational cross-sectional study in adults aged 18-65 years. The study group consisted of 90 patients (90 eyes) with chronic migraines who met the inclusion criteria, and 90 healthy controls (90 eyes) matched for age and sex. Retinal thickness was measured by spectral domain OCT (SD-OCT). The thickness of the superior quadrant of the peripapillary RNFL, as well as the mean thickness in the macula, RNFL macular, and GCL was significantly thinner in chronic migraine patients than in healthy controls (p ≤ 0.05). Chronic migraines are associated with a decrease in retinal thickness which is detectable by an OCT diagnostic technique. The quantification of the axonal damage could be used as a biomarker to help in the diagnosis and monitoring of this pathology. Further studies will be needed to confirm these findings.

Abstract
Abstract
Background
Migraine is a common, chronic, multifactorial neurovascular disorder. It may result in hypoperfusion of other areas other than the brain, as the eye. It may lead to change of the retinal nerve fiber layers (RNFL) thickness and axonal loss even up to severe damage of the eye structures, including the retina with frequent headache attacks. This study aimed to quantify the thickness of RNFL which gives a good idea about the condition of axons and loss of ganglion cells in migraine patients. Also, to detect if there is any correlation between these measurements and clinical characteristics of migraine.
Results
The RNFL thickness was significantly thinner in patients with migraine compared to healthy controls in all quadrants of retina in both sides (p value < 0.05). However, there was no significant difference in RNFL thickness in migraine patients with aura compared to patients without aura in all retinal quadrants in both sides (p value > 0.05). The headache intensity was negatively correlated with RNFL thickness in the inferior (r = − 0.342, P = 0.031) and nasal (r = − 0.349, P = 0.027) quadrants on LT side, also there was a significant positive correlation between RNFL thickness and both of nausea and tolerability in the RT superior quadrant (r = 0.467, P = 0.002); (r = 0.322, P = 0.043), respectively, but there was no significant correlation found between the RNFL thickness and disability, attacks duration, disease duration and frequency in all retinal quadrants on both sides (P > 0.05).
Conclusion
The main conclusion of our work was that RNFL thickness was significantly affected in migraine patients in comparison to healthy controls, but there were no significant impact of the migraine characteristics including aura, severity, frequency, or duration of headache attacks on RNFL thickness.

Abstract
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.

Abstract
PURPOSE To evaluate retinal nerve fiber layer (RNFL) thickness in children with migraine, with and without aura, compared to healthy controls using optical coherence tomography (OCT). METHODS In this cross-sectional case-control study, patients with a diagnosis of migraine with aura (MwA) or without aura (MwoA) were considered and healthy children were included as controls. Age, sex, duration of migraine, number of episodes per month, duration of episodes, and use of prophylactic treatment with magnesium were recorded. All patients underwent complete ophthalmologic, neurologic, and pediatric examination. Optic nerve OCT images were obtained using Heidelberg Spectralis OCT (Heidelberg Engineering) and mean global RNFL thickness and the average thickness for each sector were noted. RESULTS Thirty-seven children were included: 17 with migraine (9 MwoA and 8 MwA) and 20 controls, the mean age being 13.8 ± 2.9 (range: 8 to 16) and 13.4 ± 2.5 (range: 7 to 16) years, respectively. No significant differences in RNFL thickness were found when comparing all patients who had migraine with healthy controls. However, children with MwA showed statistically significant reductions in RNFL thickness in the temporal (mean difference: 7.83; 95% CI: 0.52 to 15.14, P = .027) and inferior-temporal (mean difference: 16.06; 95% CI: 1.95 to 30.16, P = .027) sectors compared to patients with MwoA. None of the other sectors showed statistically significant differences between groups (all P > .05). In the migraine group, negative correlations were detected between the number of episodes per month and RNFL thickness in the nasal-superior quadrant (r = -.420; P = .021). CONCLUSIONS Children with MwA may present a decrease in RNFL thickness, which is associated with the number of episodes per month. [J Pediatr Ophthalmol Strabismus. 20XX;X(X):XX-XX.].

Abstract
To compare the foveal avascular zone (FAZ), macular and peripapillary vessel density and retinal nerve fiber layer (RNFL) thickness between pediatric migraine patients and healthy subjects. A total of 108 eyes of 54 children with migraine without aura and 94 eyes of 47 age- and gender-matched healthy subjects were included. Capillary vessel density (CVD) in superficial (SCP) and deep (DCP) retinal capillary plexus, peripapillary region, FAZ, and RNFL thickness were analyzed by optical coherence tomography-angiography. The mean ages were 12.4 ± 3.3 years (range 6-18) in patients with migraine and 12.6 ± 2.9 years (range 5-18) in healthy controls (p = 0.742). The mean FAZ area measured 0.27 ± 0.09 mm2 in the pediatric migraineurs and 0.26 ± 0.09 mm2 in healthy controls (p = 0.53). There was no significant difference in any measurement of SCP, DCP, peripapillary CVD, and RNFL thickness between study groups (p > 0.05 for all). The pediatric migraine disability assessment test (PedMIDAS) negatively correlated with some of the CVD and RNFL measurements in pediatric migraine patients (p < 0.05). The macular and peripapillary microvasculature were not significantly different during an attack-free period in pediatric migraine patients than in healthy subjects.

Abstract
OBJECTIVE This study aimed to evaluate ocular vascularity in young adult migraine patients with visual aura and without visual aura. MATERIAL AND METHODS The study included 30 patients with migraine with visual aura (MWVA), 30 patients with migraine without visual aura (MWOVA), and 30 healthy control subjects, all between ages ≥18 and <45. Migraine patients were applied Headache Impact Test (HIT) and Migraine Disability Assessment Scale (MIDAS). Retinal nerve fiber layer thickness and ocular vascularity of all participants were evaluated with optical coherence tomography (OCT) and OCT angiography (OCTA). RESULTS The MWVA group had significantly lower superficial and deep foveal vascular density values compared to the control group (p = 0.039, p = 0.028, respectively). The foveal avascular zone was significantly enlarged in the MWVA group compared to the control group (p = 0.033). MWVA patients had significantly lower whole optic disc, optic disc inside, peripapillary, superior hemisphere, inferior hemisphere, superior quadrant, and temporal quadrant vascular density values compared to the control group (p < 0.05 all), while there was no significant difference in the nasal quadrant (p = 0.083). Migraine attack frequency, MIDAS, and HIT were negatively correlated with ocular vascular density values. CONCLUSION The results of our study indicate that young adult patients with MWVA are at risk of decreased ocular vascularity and that this risk may increase with frequency and severity of migraine attacks.

Abstract
PURPOSE To compare optical coherence tomography angiography (OCTA) findings in cases with migraine and healthy controls. METHODS Thirty-eight eyes of 19 patients with migraine with aura and 38 eyes of 19 healthy subjects were enrolled in this prospective and comparative study. All patients and healthy controls were evaluated with OCTA (Triton, Topcon®, Tokyo, Japan). Central macular thickness (CMT), optic disc parameters (such as retinal nerve fibre layer [RNFL] thickness and rim and disc areas), foveal avascular zone (FAZ) and parafoveal superficial vessel density (VD) measurements were analysed. RESULTS The optic disc rim area was significantly larger in the migraine group compared to the control group (p = 0.009). In OCTA measurements, the FAZ area was significantly larger in migraine patients (p = 0.001). The parafoveal superficial VD measurements were found to be lower in the migraine patients in all quadrants, but not statistically significant. Weak negative correlations were found between superior parafoveal VD and disease duration in migraine patients. CONCLUSION Migraine with aura was associated with optic disc rim changes, but without any remarkable foveal vascular decrements. It is possible for migraine to cause structural changes due to its chronic nature.

Abstract
BACKGROUND Migraine is one of the most common disabling diseases in the world. Its recurrent attacks may lead to abnormalities in the structure of the brain and retina. An increasing number of studies have investigated retinal nerve fiber layer (RNFL) thickness alterations in migraine by the optical coherence tomography (OCT); however, no consensus has yet reached. METHOD We searched Pubmed, Embase, and Web of Science databases to identify studies that investigated RNFL thickness in migraine by OCT measurement and performed a meta-analysis of eligible studies. RESULTS Twenty-six studies were included in the meta-analysis, comprising 1530 migraine patients and 1105 healthy controls. The mean RNFL thickness was thinner in the migraine group compared to the control group (SMD =- 0.53). In the subgroup analyses, RNFL thickness were decreased most significantly in the superior (SMD = - 0.71) and inferior (SMD = - 0.63) quadrants among all quadrants. Migraine with aura (SMD = - 0.91) showed a greater effect size of RNFL thickness reduction than migraine without aura (SMD =- 0.47). Spectral-domain OCT (SMD = - 0.55) seems more sensitive to detect RNFL thickness reduction than time-domain OCT (SMD = - 0.44). In addition, age, sex, disease duration, attack frequency, and intraocular pressure were not significantly associated with RNFL thickness. CONCLUSIONS The findings from our comprehensive meta-analysis with large datasets strengthen the clinical evidence of the RNFL thickness reduction in migraine. RNFL thickness via spectral-domain OCT measurement demonstrates the potential role in differentiating patients with migraine, especially migraine with aura, from healthy controls.

Our work aimed to investigate if the retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) thickness are affected in patients with chronic migraine to improve the understanding of the etiology and pathophysiology of migraine.
Subjects and methods
A case-control study conducted on 30 patients with chronic migraine and 30 aged and sex-matched healthy controls. Subjects underwent full neurological and ophthalmological history, ophthalmological examination, and measuring RNFL and GCL thickness using the spectral domain-optical coherence tomography (SD-OCT).
Results
RNFL thinning (average, superior, inferior, nasal, and temporal) was significantly more in patients with chronic migraine than healthy control (P = 0.001, 0.022, 0.045, 0.034, and 0.001, respectively). No statistically significant difference was found between chronic migraine patients and healthy controls regarding GCL thickness (average, superior, and inferior) (P value ˃ 0.05).
The average RNFL thickness was significantly thinner in migraine with aura (MwA) than migraine without aura (MwoA) (P = 0.006). The average GCL thickness was thinner in MwA than MwoA (P = 0.039). No statistically significant difference was found between the eyes on the side of the headache and the eyes of the contralateral side regarding RNFL and GCL thickness (P value ˃ 0.05). Age at onset, disease duration, headache frequency, and headache intensity showed an insignificant correlation with OCT parameters.
Conclusion
Retinal changes could be an association with chronic migraine that may be used as a biomarker.

Abstract
PURPOSE Migraine is thought to be a neurovascular disorder and increases the likelyhood to develop ischemic complications. Studies have shown that vascular disorders such as ischemic optic neuropathy, retinal artery and vein obstructions are more common in patients with migraine. This study aimed to evaluate the differences between retinal and optic disc microvasculature between migraine patients with and without aura and healthy controls using optical coherence tomography angiography (OCTA) imaging. METHODS Thirty-three patients with migraine and 28 healthy subjects were included in this prospective cross sectional study. Optical coherence tomography angiography imaging was performed for the macula and optic disc. Vessel densities (VD) and choriocapillaris flow values were compared between three groups: control group, migraine with aura (MWA), and migraine without aura (MWOA). RESULTS There was no difference between the three groups for the VDs of the foveal, perifoveal, parafoveal, and the whole area. The choriocapillaris flow of patients with MWA was significantly less than that of the MWOA and control groups. The VDs of the optic disc revealed no significant difference between the three groups. CONCLUSION A lack of choriocapillaris autoregulatory mechanisms may be a possible cause of the decrease in choriocapillaris flow in patients with MWA.

Abstract
BACKGROUND Migraine is one of the most common disorders and its pathophysiological mechanisms are still under research, oxidative stress being emphasized as an important contributor. This study aimed to analyze the retinal nerve fiber layer (RNFL) thickness and oxidative/anti-oxidant balance in migraine patients. METHODS Two groups of subjects were evaluated: a group of patients with migraine and a control group of healthy volunteers. RNFL thickness was assessed for all subjects by the ocular coherence tomography spectral domain (OCT-SD). The oxidative stress parameter, namely nitric oxide (NOx), malondialdehyde (MDA), and total oxidative stress (TOS) were assessed. The antioxidant capacity of plasma was evaluated by assessing the level of catalase, and total anti-oxidative (TOS) capacity. Migraine severity was graded using the Migraine Disability Assessment Score (MIDAS) questionnaire. RESULTS All the oxidative stress parameters (NOx, MDA, and TOS) were significantly increased, and both parameters for anti-oxidative status were significantly decreased in the migraine group compared with the control group (p < 0.0001). Significant correlations with all the quadrants and different oxidative stress parameters were found, most involved being temporal quadrant. A significant positive correlation between catalase and macular RNFL thickness (inner ring, temporal quadrant) in migraine patients, for both eyes, was observed (p = 0.014 for the right eye and p = 0.12 for the left eye). CONCLUSION The assessment of the oxidative stress/anti-oxidative balance together with RFLN thickness can constitute a promising method to evaluate the progression of the diseases. It can also contribute to the estimation of the efficiency of various therapies targeting oxidative stress and associated inflammation.

Altered Macular Vasculature in Migraine Patients without Aura: Is It Associated with Ocular Vasculature and White Matter Hyperintensities? J Ophthalmol 2020; 2020:3412490. [PMID: 32351718 PMCID: PMC7174908 DOI: 10.1155/2020/3412490] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2019] [Accepted: 03/30/2020] [Indexed: 11/17/2022] Open
Abstract
Aim We aimed to determine the alterations in macular and optic nerve vasculature in patients with migraine without aura using optical coherence tomography-angiography (OCTA). We also aimed to determine whether there were clinical differences and alterations in ocular structures in migraine cases with white matter hyperintensities (WMH) using magnetic resonance imaging (MRI). Materials and Methods. The study group comprised patients with migraine without aura and age- and sex-matched healthy controls. Detailed histories of the patients with migraine were recorded including the disease duration, number of attacks in the last month, and attack durations. Visual evoked potentials (VEP) were recorded in all migraine patients. The migraine disability assessment (MIDAS) questionnaire was administered to all patients. The patients were divided into two groups as migraine with WMHs and migraine without WMHs. All subjects underwent a complete neurological and ophthalmological examination. Only the right eyes of the patients were included in the study. Retinal imaging was performed using OCT and OCTA. Results A total of 66 migraine patients (29 with WMH and 37 without WMH) and 43 healthy controls were included in this study. Among the migraine patients, disease duration, attack frequency in the last month, attack durations, and the visual analogue scale (VAS), MIDAS, and VEP scores were all similar between those with and without WMHs. There was no significant difference between the groups regarding the ganglion cell complex, foveal, and retinal nerve fiber layer thicknesses. The superficial or deep vascular perfusion densities of the optic disc were also similar between the groups. The foveal avascular zone (FAZ) was significantly larger (P=0.034), and both superficial and deep macular vascular densities were significantly lower in the migraine groups compared with the healthy controls (P=0.001). There was no significant difference concerning the FAZ size or vascular densities between the migraine groups with and without WMHs. In the correlation analysis performed between the migraine patients, the FAZ size was correlated with age and VAS and MIDAS scores while both superficial and deep macular vascular densities were negatively correlated with age and VAS and MIDAS scores. Conclusion We suggest that for not only migraine with aura but also migraine without aura, neurovascular structures play an important role in pathogenesis, and novel studies are warranted to elucidate the alterations in these and determine the significance of WMHs in these patient groups.

Abstract
PURPOSE To compare the choroidal thickness (CT) of the affected eyes with the contralateral eyes in the active period and in the remission period in Posner-Schlossman syndrome (PSS) using EDI-OCT. PATIENTS AND METHODS This prospective longitudinal study included 15 patients with PSS and 15 age- and sex-matched healthy subjects. All subjects underwent complete ophthalmologic examinations, and EDI-OCT was conducted to measure macular CT (mCT) at the subfoveal locations and at 0.5, 1.0 and 2.0 mm superior, inferior, nasal and temporal to the fovea. The mean measurements at each location were used for analysis. Linear regression analysis was performed to analyse the correlation between the choroidal thickness and IOP, and the correlation between the choroidal thickness and episode time. RESULTS The mean mCT was significantly thinner in affected eyes than in contralateral eyes in the acute phase (p = 0.010) but were not different in the remission phase (p = 0.404). The mean mCT was significantly increased in the remission phase compared to that in the acute phase in the affected eyes (p = 0.000). The mCT of healthy subjects was significantly thicker than in the affected eyes (p = 0.020) and similar to the fellow eyes of PSS patients (p = 0.357) in the acute phase. Linear regression analyses show negative correlations between the mCT changes and IOP changes in the affected eyes compared to those in the fellow eyes in the acute period (R2 = 0.396, p = 0.033) and between the mCT changes and IOP changes from the acute period to the remission period in the affected eyes (R2 = 0.372, p = 0.027). Linear regression analyses show positive correlations (age- and sex-matched) between the CT changes and episode time from the affected eyes to the fellow eyes in the acute period (R2 = 0.492, p = 0.012). CONCLUSIONS The mCT values of the PSS-affected eyes were significantly thinner than those of the fellow eyes in the acute phase and in the remission phase, and this change was correlated with IOP reduction and episode time.

Abstract
Underlying pathophysiological mechanism of migraine is not all clear; however, recent reports suggested that neurovascular system is involved. We aimed to evaluate the retinal vessel densities of migraine patients with and without aura and the associations with white matter hyperintensities (WMH), using optical coherence tomography angiography (OCTA). We recruited 28 migraine with aura (MWA) patients, 26 migraine without aura (MWO) and age and sex-matched 34 healthy controls in our study. All participants were evaluated with optical coherence tomography (OCT) and OCTA for optic nerve parameters and retinal vessel densities with RTVue XR AVANTI. On macular OCTA, superficial and deeper retinal foveal vessel density (VD) were significantly lesser in MWA and MWO than controls. On optic nerve OCTA, whole optic disc, peripapillary, superior hemisphere, superior layer and temporal layer VD were significantly lesser in MWA and MWO. In group of MWA with the WMH, deeper foveal VD and superior hemisphere VD, average RNFL, superior hemisphere and superior layer were significantly lesser and also foveal avascular zone was significantly larger than the group of without WMH. Alterations of VD in patients with migraine are showed in our study. In addition, in group of MWA these alterations have associations with WMH. Supporting these findings with further reports can be useful to understand the pathophysiology of this disease.

Abstract
Purpose: To investigate the factors in migraine that have the highest significance on retinal and choroidal layers’ thickness. Methods: Ninety patients with migraine and 40 age-matched healthy participants were enrolled in this observational, cross-sectional study. After full ophthalmological examination, spectral domain-optical coherence tomography was done for all patients measuring the thickness of ganglion cell layer and retinal nerve fiber layer. Enhanced depth imaging technique was used to measure the choroidal thickness. Results: There was significant thinning in the superior and inferior ganglion cell layers, all retinal nerve fiber layer quadrants, and all choroidal quadrants (except for the central subfield) in migraineurs compared to controls. The duration of migraine was significantly correlated with ganglion cell layer, retinal nerve fiber layer, and all choroidal quadrants, while the severity of migraine was significantly correlated with ganglion cell layer and retinal nerve fiber layer only. Multiregression analysis showed that the duration of migraine is the most important determinant factor of the superior retinal nerve fiber layer quadrant (β = −0.375, p = 0.001) and in all the choroidal quadrants (β = −0.531, −0.692, −0.503, −0.461, −0.564, respectively, p < 0.001), while severity is the most important determinant factor of inferior, nasal, and temporal retinal nerve fiber layer quadrants (β = −0.256, −0.335, −0.308; p = 0.036, 0.005, 0.009, respectively) and the inferior ganglion cell layer hemisphere (β = −0.377 and p = 0.001). Conclusion: Ganglion cell layer, retinal nerve fiber layer, and choroidal thickness are significantly thinner in patients with migraine. The severity of migraine has more significant influence in the thinning of ganglion cell layer and retinal nerve fiber layer, while the duration of the disease affected the choroidal thickness more.

Abstract
Migraine is a chronic disease characterized by unilateral, pulsating, and often moderate-to-severe recurrent episodes of headache with nausea and vomiting. It affects approximately 15% of the general population, yet the underlying pathophysiological mechanisms are not fully understood. Optical coherence tomography (OCT) is a safe and reproducible diagnostic technique that utilizes infrared wavelengths and has a sensitivity of 8–10 μm. It can be used to measure thinning of the retinal nerve fiber layer (RNFL) in some neurological disorders. Although ophthalmologists are often the first specialists to examine patients with migraine, few studies have addressed the involvement of the optic nerve and retino-choroidal structures in this group. We reviewed the literature on the etiological and pathological mechanisms of migraine and the relationship between recurrent constriction of cerebral and retrobulbar vessels and ischemic damage to the optic nerve, retina, and choroid. We also assessed the role of OCT for measuring peripapillary RNFL thickness and macular and choroidal changes in migraine patients. There is considerable evidence of cerebral and retrobulbar vascular involvement in the etiology of migraine. Transitory and recurrent constriction of the retinal and ciliary arteries may cause ischemic damage to the optic nerve, retina, and choroid in patients with migraine. OCT to assess the thickness of the peripapillary RNFL, macula, and choroid might increase our understanding of the pathophysiology of migraine and facilitate diagnosis of retino-choroidal compromise and follow-up of therapy in migraine patients. Future studies should determine the usefulness of OCT findings as a biomarker of migraine.

Abstract
Purpose Migraine, particularly with aura, has been associated with ocular and systemic ischemic complications, but there are limited data on the ocular vasculature in migraine. We used optical coherence tomography angiography (OCTA) to assess perfusion of the macula and optic nerve in migraine patients, with (MA) and without (MO) aura, compared to healthy controls (HC). Methods We recruited 15 MA (mean age 42 years), 12 MO (mean age 46 years), and 22 HC (mean age 39 years) participants from neurology and neuro-ophthalmology clinics. Participants underwent optical coherence tomography and 3 × 3 mm OCTA of the macula and optic nerve. Foveal avascular zone area was automatically measured using AngioVue software, and vessel density was calculated as blood vessel length divided by scan area (mm-1) after skeletonization of OCTA images. Results On macular OCTA, MA participants had an enlarged foveal avascular zone area when compared with HC (0.300 ± 0.019 vs. 0.220 ± 0.066 mm2, P = 0.006). In addition, superficial foveal vessel density was decreased in MA participants when compared with MO participants (7.8 ± 0.31 vs. 9.3 ± 0.44, P = 0.04) and HC (7.8 ± 0.31 vs. 9.4 ± 0.21 mm-1, P = 0.002). On optic nerve OCTA, the MA participants had reduced superior peripapillary vessel density when compared with the MO participants (12.0 ± 0.45 vs. 14.0 ± 0.38 mm-1, P = 0.031) and HC (12.0 ± 0.45 vs. 14.1 ± 0.53 mm-1, P = 0.035). There were no significant differences between the MO and HC groups. Conclusions Migraine with, but not without, aura was associated with foveal and peripapillary vascular decrements, which may possibly mediate increased risk of ocular and systemic vascular complications in these patients. OCTA could potentially be useful as a biomarker for migraine with aura.

Abstract
PURPOSE To evaluate the thickness of the peripapillary retinal nerve fiber layer (RNFL), total macula, macular ganglion cell layer (GCL), inner plexiform layer (IPL), and choroid in pediatric migraine patients and compare the values with healthy subjects. METHODS This observational and cross-sectional study included 40 patients in the migraine group and 40 healthy control subjects. The thickness of the peripapillary RNFL, total macula, GCL, and IPL was analyzed with spectral-domain optic coherence tomography, while choroidal thickness was analyzed with the enhanced depth imaging protocol. All measurements of the migraine patients were taken in the attack-free period. Right eye selected per subject was included in the study. RESULTS There was no significant difference between the 2 groups in age or sex (p>0.05). The peripapillary RNFL thickness was not significantly different between the 2 groups in any quadrant. The total macula, GCL, and IPL thickness were also not significantly different in the 9 separate macular areas defined on the basis of the Early Treatment Diabetic Retinopathy Study (p>0.05). The choroidal thickness at 5 different measurement points was not statistically significantly different between migraine patients during the attack-free period and the healthy subjects (p>0.05). CONCLUSIONS Childhood migraine does not cause changes in posterior ocular structure parameters.

Abstract
Aim To compare the relationship between white matter hyperintensities (WMH) on brain magnetic resonance imaging and retinal nerve fiber layer (RNFL), choroid, and ganglion cell layer (GCL) thicknesses in migraine patients and healthy subjects. We also assessed the role of cerebral hypoperfusion in the formation of these WMH lesions. Methods We enrolled 35 migraine patients without WMH, 37 migraine patients with WMH, and 37 healthy control subjects examined in the Neurology outpatient clinic of our tertiary center from May to December 2015. RFNL, choroid, and GCL thicknesses were measured by optic coherence tomography. Results There were no differences in the RFNL, choroid, or GCL thicknesses between migraine patients with and without WMH ( p > 0.05). Choroid layer thicknesses were significantly lower in migraine patients compared to control subjects ( p < 0.05), while there were no differences in RFNL and GCL thicknesses ( p > 0.05). Conclusions The ‘only cerebral hypoperfusion’ theory was insufficient to explain the pathophysiology of WMH lesions in migraine patients. In addition, the thinning of the choroid thicknesses in migraine patients suggests a potential causative role for cerebral hypoperfusion and decreased perfusion pressure of the choroid layer.

Abstract
Background The aim of this study was to assess the intraocular pressure and ocular biometric parameters in migraine patients during acute migraine attacks and compare them with painless period and healthy controls using a new optical biometer AL-Scan. Methods In this prospective, case–control study, the axial length, corneal curvature radius, anterior chamber depth, central corneal thickness, and pupil size of 40 migraine patients during acute migraine attacks and painless period and 40 age- and sex-matched healthy subjects were measured using a AL-Scan optical biometer (Nidek Co., Gamagori, Japan). All patients underwent a complete ophthalmic examination before the measurements. IOP and biometer measurements were taken at the same time of day (10:00–12:00) in order to minimize the effects of diurnal variation. Results There was not a statistically significant difference in intraocular pressure between the migraine patients during acute migraine attacks (15.07 mmHg), painless period (14.10 mmHg), and the controls (15,73 ± 0,81). Also, the ocular biometric parameters did not significantly vary during the acute migraine attacks. Conclusions Further studies are needed to evaluate the etiopathologic relationship between intraocular pressure and ocular biometric parameters and acute migraine attack.

Abstract
This study investigated whether migraine influences the risk of primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG) in Taiwan.We retrieved the data analyzed in this study from the National Health Insurance Research Database in Taiwan. We included 17,606 newly diagnosed migraine patients without preexisting glaucoma and randomly selected and matched 70,423 subjects without migraine as the comparison cohort. The same exclusion criteria were also applied to comparison subjects. Multivariate Cox proportion-hazards regression model was used to assess the effects of migraines on the risk of glaucoma after adjusting for demographic characteristics and comorbidities.The cumulative incidence of POAG was higher in the migraine cohort than that in the comparison cohort (log-rank P = 0.04). The overall incidence of POAG (per 10,000 person-years) was 9.62 and 7.69, respectively, for migraine cohort and nonmigraine cohort (crude hazard ratio [HR] = 1.24, 95% confidence interval [CI] = 1.01-1.54). After adjusting the covariates, the risk of POAG was not significantly higher in the migraine cohort than in the comparison cohort (adjusted HR [aHR] = 1.15, 95% CI = 0.93-1.42). The cumulative incidence of PACG did not differ between the migraine cohort and the comparison cohort (log-rank test P = 0.53). The overall incidence of PACG was not significantly higher in the migraine cohort than that in the comparison cohort (7.42 vs 6.84 per 10,000 person-years), with an aHR of 1.04 (95% CI = 0.82-1.32).This study shows that migraines are not associated with a higher risk either in POAG or in PACG.

Abstract
AIM To investigate the alterations in foveal retinal thickness (FT) values in patients with migraine and to reveal the correlations between FT and clinical characteristics of migraine disease. METHODS This study included sixty-eight eyes of 34 migraine patients [twenty-eight eyes of 14 patients with aura (group 1), and forty eyes of 20 patients without aura (group 2)] and forty eyes of 20 healthy volunteer who served as the control group (group 3). FT values were measured by optical coherence tomography (OCT) in each group. RESULTS Mean age of patients in group 1, 2, and 3 was 34.0± 6.82, 35.2±10.12, and 35.1± 6.85 years, respectively (p=0.84). Mean FT was 211.07±7.36, 220.0±12.01, and 221.85±12.27 in groups 1, 2, and 3, respectively. There was statistically significance among the group 1-2 and 1-3 (p=0.002 and p< 0.001). There was no statistically significance between group 2-3 (p=0.88). CONCLUSION This study suggests that in particular migraine with aura may lead to a reduction in FT values. This finding can be explained by the blood flow decrease theory in migraine; however larger studies seem mandatory.
