ABSTRACT
Vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been rapidly developed to prevent coronavirus disease 2019 (COVID-19) pandemic. There is increasing safety concerns regarding COVID-19 vaccines. We report a 78-year old woman who was presented with tetraparesis, paresthesias of bilateral upper extremities, and urinary retention of one-day duration. Three weeks before these symptoms, she was vaccinated with CoronaVAC vaccine (Sinovac Life Sciences, China). Spine magnetic resonance imaging showed longitudinally extensive transverse myelitis (TM) from the C1 to the T3 spinal cord segment. An extensive diagnostic workup was performed to exclude other possible causes of TM. We suggest that longitudinally extensive TM may be associated with COVID-19 vaccination in this case. To the best of our knowledge, this is the first report of longitudinally extensive TM developing after CoronaVac vaccination. Clinicians should be aware of neurological symptoms after vaccination of COVID-19.

OBJECTIVES: Headache is the most common complaint in cerebral venous sinus thrombosis (CVST) and it may sometimes be the only symptom in these patients. This retrospective and prospective study was an investigation of any differences in terms of clinical risk factors, radiological findings, or prognosis in patients with CVST who presented with isolated headache (IH) and cases with other concomitant findings (non-isolated headache [NIH]). METHODS: A total of 1144 patients from a multicenter study of cerebral venous sinus thrombosis (VENOST study) were enrolled in this research. The demographic, biochemical, clinical, and radiological aspects of 287 IH cases and 857 NIH cases were compared. RESULTS: There were twice as many women as men in the study group. In the IH group, when gender distribution was evaluated by age group, no statistically significant difference was found. The onset of headache was frequently subacute and chronic in the IH group, but an acute onset was more common in the NIH group. Other neurological findings were observed in 29% of the IH group during follow-up. A previous history of deep, cerebral, or other venous thromboembolism was less common in the IH group than in the NIH group. Transverse sinus involvement was greater in the IH group, whereas sagittal sinus involvement was greater in the NIH group. The presence of a plasminogen activator inhibitor (PAI) mutation was significantly greater in the IH group. CONCLUSION: IH and CVST should be kept in mind if a patient has subacute or chronic headache. PAI, which has an important role in thrombolytic events, may be a risk factor in CVST. Detailed hematological investigations should be considered. Additional studies are needed.

Headache is a common symptom of cervical artery dissections (CAD). Sometimes, it can be the only symptom and mimic migraine. We aimed to investigate headache characteristics and previous history of migraine in CAD patients, and to compare headache features between patients with internal carotid artery dissection (ICAD) and vertebral artery dissection (VAD). We investigated 53 CAD patients (n = 28 with ICAD, n = 25 with VAD). Demographic and clinical data were evaluated retrospectively. Headache information was obtained from the patient interviews with a structured questionnaire (based on the International Headache Society criteria). The patients with headache were assessed by headache specialist with a face-to-face interview. Headache was evaluated according to International Classification Committee of the International Headache Society ICHD. Headache (n = 38, 71.7%) was the most common symptom in CAD patients, which was mostly thunderclap, throbbing, intense and ipsilateral to dissection. Headache frequency and neck pain were significantly higher in VAD patients (p = 0.002, p < 0.001, respectively). Photophobia and phonophobia were also more common in patients with VAD (p < 0.001, p < 0.001, respectively). 29 (54.7%) of CAD patients had a prior history of headache, that 20 (37.7%) of them met the migraine criteria. CAD should be considered in patients with severe unilateral throbbing headache with phonophobia and photophobia, even in patients with a history of migraine. Phonophobia and photophobia may be more common symptoms in VAD patients. Because headache commonly precedes the development of cerebral ischemic events, it needs prompt and accurate diagnosis and treatment.

INTRODUCTION: Cerebral venous and sinus thrombosis (CVST) may lead to cerebral edema and increased intracranial pressure; besides, ischemic or hemorrhagic lesions may develop. Intracerebral hemorrhages occur in approximately one-third of CVST patients. We assessed and compared the findings of the cerebral hemorrhage (CH) group and the CVST group. MATERIALS AND METHODS: In the VENOST study, medical records of 1,193 patients with CVST, aged over 18 years, were obtained from 35 national stroke centers. Demographic characteristics, clinical symptoms, signs at the admission, radiological findings, etiologic factors, acute and maintenance treatment, and outcome results were reported. The number of involved sinuses or veins, localizations of thrombus, and lesions on CT and MRI scans were recorded. RESULTS: CH was detected in the brain imaging of 241 (21.1%) patients, as hemorrhagic infarction in 198 patients and intracerebral hemorrhage in 43 patients. Gynecologic causes comprised the largest percentage (41.7%) of etiology and risk factors in the CVST group. In the CH group, headache associated with other neurological symptoms was more frequent. These neurological symptoms were epileptic seizures (46.9%), nausea and/or vomiting (36.5%), altered consciousness (36.5%), and focal neurological deficits (33.6%). mRS was ≥3 in 23.1% of the patients in the CH group. DISCUSSION AND CONCLUSION: CVST, an important cause of stroke in the young, should be monitored closely if the patients have additional symptoms of headache, multiple sinus involvement, and CH. Older age and parenchymal lesion, either hemorrhagic infarction or intracerebral hemorrhage, imply poor outcome.

PURPOSE: The aim of this study is to evaluate the presence and prognostic impact of early seizures in cerebral venous sinus thrombosis patients (CVST). METHOD: VENOST is a retrospective and prospective national multicenter observational study. CVST patients with or without epileptic seizures (ES) were analyzed and compared in terms of demographic and imaging data, causative factors, clinical variables, and prognosis in a total of 1126 patients. RESULTS: The mean age of the patients in the ES group was 39.73 ± 12.64 and 40.17 ± 14.02 years in the non-ES group (p > 0.05). Epileptic seizures were more common (76.6 %) in females (p < 0.001). Early ES occurred in 269 of 1126 patients (23.9 %). Epileptic seizures mainly presented in the acute phase (71.4 %) of the disease (p < 0.001). Majority of these (60.5 %) were in the first 24 h of the CVST. The most common neurological signs were focal neurologic deficits (29.9 %) and altered consciousness (31.4 %) in the ES group. Superior sagittal sinus (SSS) and cortical veins (CV) involvement were the most common sites of thrombosis and the mostly related etiology were found puerperium in seizure group (30.3 % vs 13.9 %). Patients with seizures had worse outcome in the first month of the disease (p < 0.001) but these did not have any influence thereafter. CONCLUSIONS: In this largest CVST cohort (VENOST) reported female sex, presence of focal neurological deficits and altered consciousness, thrombosis of the SSS and CVs, hemorrhagic infarction were risk factors for ES occurrence in patients with CVST.

AIM: Systemic lupus erythematosus (SLE) is an unusual risk factor for cerebral venous sinus thrombosis (CVST). As few CVST patients with SLE have been reported, little is known regarding its frequency as an underlying etiology, clinical characteristics, or long-term outcome. We evaluated a large cohort of CVST patients with SLE in a multicenter study of cerebral venous thrombosis, the VENOST study, and their clinical characteristics. MATERIAL AND METHOD: Among the 1144 CVST patients in the VENOST cohort, patients diagnosed with SLE were studied. Their demographic and clinical characteristics, etiological risk factors, venous involvement status, and outcomes were recorded. RESULTS: In total, 15 (1.31%) of 1144 CVST patients had SLE. The mean age of these patients was 39.9 ± 12.1 years and 13 (86.7%) were female. Presenting symptoms included headache (73.3%), visual field defects (40.0%), and altered consciousness (26.7%). The main sinuses involved were the transverse (60.0%), sagittal (40.0%), and sigmoid (20.0%) sinuses. Parenchymal involvement was not seen in 73.3% of the patients. On the modified Rankin scale, 92.9% of the patients scored 0-1 at the 1-month follow-up and 90.9% scored 0-1 at the 1-year follow-up. CONCLUSIONS: SLE was found in 1.31% of the CVST patients, most frequently in young women. Headache was the most common symptom and the CVST onset was chronic in the majority of cases. The patient outcomes were favorable. CVST should be suspected in SLE patients, even in those with isolated chronic headache symptoms with or without other neurological findings.

OBJECTIVE: This study was performed to determine the rate of cerebral venous sinus thrombosis (CVST) among cases of Behçet's disease (BD) included in a multicentre study of cerebral venous sinus thrombosis (VENOST). METHODS: VENOST was a retrospective and prospective national multicentre observational study that included 1144 patients with CVST. The patients were classified according to aetiologic factors, time of CVST symptom onset, sinus involvement, treatment approach and prognosis. RESULTS: BD was shown to be a causative factor of CVST in 108 (9.4%) of 1144 patients. The mean age of patients in the BD group was 35.27 years and 68.5% were men, whereas in the non-BD CVST group, the mean age was 40.57 years and 28.3% were men (P < 0.001). Among the aetiologic factors for patients aged 18-36 years, BD was predominant for men, and puerperium was predominant for women. The onset of symptoms in the BD group was consistent with the subacute form. The transverse sinuses were the most common sites of thrombosis, followed by the superior sagittal sinuses. The most common symptom was headache (96.2%), followed by visual field defects (38%). CONCLUSIONS: BD was found in 9.4% of patients in our VENOST series. Patients with BD were younger and showed a male predominance. The functional outcome of CVST in patients with BD was good; only 12% of patients presenting with cranial nerve involvement and altered consciousness at the beginning had a poor outcome (modified Rankin Score ⩾2).

INTRODUCTION: The Type D personality was reported as an important indicator of adverse clinical outcomes and quality of life in various diseases. The objective of this study was to investigate the relationships between the Type D personality and clinical features and the effect of Type D personality on quality of life in patients with multiple sclerosis (MS). METHODS: Seventy-four patients with MS participated in this study. Clinical parameters of the patients were recorded and disability was assessed using the Expanded Disability Status Scale (EDSS). Patients were examined with the Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Type D Scale (DS14), and 36-Item Short-Form Health Survey (SF-36). RESULTS: BDI and BAI scores were significantly higher and mental subscale of the SF-36 scores were significantly lower in Type D compared to nonType D (p<0.001, p=0.001, and p<0.001, respectively). The total DS14 scores were found to be positively correlated with EDSS, BDI, and BAI and negatively correlated with SF-36 mental subscale (p=0.02, p<0.001, p<0.001, and p<0.001, respectively). Multivariate linear regression analysis indicated that the total DS14 score was independently associated with the mental component of SF-36 (p<0.001). CONCLUSION: The Type D personality traits may worsen the quality of life, particularly the mental component, in patients with MS. Consequently, the assessment of MS patients by brief and valid DS14 may be valuable for clinical practice.
ABSTRACT
OBJECTIVES: This study aimed to investigate the effect of temperament and character traits on perceived social support and quality of life in patients with epilepsy (PWE). METHODS: Fifty-two PWE and 54 healthy controls were included in this study. Demographics and clinical data were recorded. Temperament and Character traits were investigated using Temperament and Character Inventory (TCI), Perceived Social Support was evaluated by Multidimensional Scale of Perceived Social Support Scale (MSPSS), and quality of life was assessed using a 36-Item Short-Form Health Survey (SF-36). Participants also completed the Hospital Anxiety Depression Scale (HADS). RESULTS: TCI and MSPSS scores showed no significant difference between the groups (p>0.05). Mental and physical subscales of SF-36 were significantly lower in PWE than the controls (p=0.012, p=0.020, respectively). Multiple linear regression analysis indicated that Reward Dependence and Cooperativeness were independent predictors for perceived social support, and Persistence score was an independent predictor for the physical subscale of SF-36 even after adjustment for confounding background variables (p<0.05, for all). CONCLUSION: Temperament and character traits may affect perceived social support and quality of life in PWE. Thus, an evaluation of temperament and character traits may play a significant role in preventing negative effects on perceived social support and quality of life in PWE.

The present study aimed to examine the frequency of restless legs syndrome (RLS) in pediatric patients with migraine and tension-type headache (TTH) and to investigate accompanying migrainous symptoms, sleep characteristics, as well as levels of serum ferritin between the pediatric migraine patients with RLS and those without RLS. We included 65 consecutive patients diagnosed with migraine, 20 patients with TTH, and 97 headache-free children in our study. Demographic, clinical, and laboratory data were noted. The presence of a primary headache was diagnosed using the ICHD-II criteria, and RLS was determined with face-to-face interviews conducted by an experienced neurologist based on the revised International RLS Study Group criteria for pediatrics. The frequency of RLS in pediatric migraine and TTH patients was significantly higher than in the controls (p = 0.0001 and p = 0.025, respectively). The frequencies of allodynia, vertigo/dizziness, and self-reported frequent arousals were significantly higher, and serum ferritin levels were significantly lower in migraine patients with RLS compared to those without RLS (p = 0.05, p = 0.028, p = 0.02, and p = 0.038, respectively). Our study suggests that the frequency of RLS is higher in pediatric migraine and TTH patients compared to controls. Therefore, pediatric headache patients should be questioned about the presence of RLS, as this co-occurrence may lead to more frequent accompanying migrainous symptoms and sleep disturbances.

Migraine and asthma are comorbid chronic disorders with episodic attacks thought to involve inflammatory and neurological mechanisms. The objective of the present study is to investigate the relationship of asthma features between the asthma patients with migraine and those without migraine headache. A cross-sectional study was conducted from October 2015 to June 2016. Physician-diagnosed asthma patients aged 18 years and above were included. Demographic data, pulmonary function test and treatment of asthma were recorded. Asthma control was assessed using the asthma control test (ACT) and asthma control questionnaire (ACQ). The diagnosis of migraine was made by the neurologist with face-to face examinations based on the International Classification of Headache Disorders, third edition beta (ICHD-III-beta) criteria. Data about the age at onset, frequency of headache attacks, duration of headache attack, the presence of aura, and severity of headache were recorded. The severity of headache was evaluated using visual analogue scale (VAS). Overall 121 asthma patients were included in this study. Migraine was found to be present in 32 (26.4%) of patients. No statistically significant difference was found between asthma group and asthma with migraine groups in terms of pulmonary function test parameters. The mean ACT score in asthma with migraine patients group was significantly lower than the asthma groups. Morever, in the group asthma with migraine, a negative significant correlations were found between ACT scores with VAS scores. This study demonstrates that migraine headache may be associated with poor asthma control. On the other hand, it should not be forgotten that ACT is a subjective test and can be affected from by many clinical parameters.

OBJECTIVE: The present study aims to analyze the levels of resistin, tumor necrosis factor alpha (TNF-α), interleukin (IL)-1ß, IL-6, IL-18, and C-reactive protein (CRP) in patients with Alzheimer's disease (AD) and also investigate a potential relationship between resistin levels and TNF-α, IL-1ß, IL-6, IL-18, and CRP levels in patients with AD. METHODS: The study included fifty patients with AD and 30 healthy controls with normal cognitive functions. The serum resistin, TNF-α, IL-1ß, IL-6, IL-18, and CRP levels were assessed. We performed a Mini-Mental State Examination (MMSE) to evaluate the general cognitive performance. RESULTS: The mean serum resistin, IL-1ß, IL-18, and TNF-α levels were significantly higher in patients with AD compared with the controls (p=0.026, p=0.002, p=0.003, and p=0.038, respectively). The IL-6 and CRP levels did not differ between the groups (p=0.874 and p=0.941). The resistin levels were positively correlated with the levels of CRP and IL-18 (r=0.526, pï¼0.001; r=0.402, p=0.004, respectively). MMSE scores and inflammatory markers were not correlated (pï¼0.05 for all). CONCLUSION: Serum resistin levels were significantly increased and correlated with some inflammatory markers in AD patients, suggesting that resistin might play a role in the inflammatory process of AD.
ABSTRACT
Cardiac autonomic dysfunction assessed by the presence of arrhythmia, by the methods, such as heart rate variability or blood pressure variability, and by the electrocardiographic abnormalities is common in Guillain-Barré syndrome (GBS). The goal of present study was to analyze the P-wave dispersion (PWD), which is the non-invasive marker of atrial arrhythmia, in GBS patients and to compare those with healthy individuals. Thirty-five patients with GBS (mean age 53.6 ± 15.5 years) and 35 healthy controls (mean age 49.2 ± 14.1 years) were included to this study. Demographic and clinical information of the patients with GBS were assessed retrospectively. A 12-lead surface electrocardiogram was acquired from all participants. Minimum and maximum P-wave duration and PWD were measured in the patients with GBS and healthy controls. Maximum P-wave duration and PWD were significantly longer, and minimum P-wave duration was significantly lower in the patients with GBS rather than the control group (p = 0.037, p < 0.001, p = 0.007, respectively). GBS disability scores were positively correlated with the maximum P-wave duration (p = 0.015, r = 0.406) and PWD (p = 0.001, r = 0.525). We found that PWD was significantly prolonged in GBS patients compared with the controls. The increased PWD which is cheap, quick, non-invasive and feasible electrocardiographic marker may be related to increased risk for atrial fibrillation in patients with GBS.

OBJECTIVE: Early degeneration of the knees might occur in patients with multiple sclerosis secondary to balance and walking impairment and muscle weakness. The aims of this study were to evaluate the knee joints of patients with multiple sclerosis compared with healthy controls, using ultrasono-graphy, and to investigate whether there is any correlation between femoral cartilage degeneration and disease-related parameters. DESIGN: Study participants were 79 patients with multiple sclerosis and 60 healthy controls. The disease-related parameters, Expanded Disability Status Scale (EDSS), Western Ontario and McMaster Universities (WOMAC) osteoarthritis index, visual analogue scale (VAS) for pain severity, and Berg Balance Scale (BBS) scores were recorded. Femoral cartilage and knee effusion were evaluated using ultrasonography. RESULTS: Femoral cartilages of patients with multiple sclerosis were more degenerated than those of healthy controls. Moreover, patients with multiple sclerosis had more effusion in their knees than did controls. In the multiple sclerosis group there was no correlation between cartilage degeneration grade, amount of effusion, and VAS-pain, BBS, WOMAC and EDSS scores. CONCLUSION: Patients with multiple sclerosis may have more rapid degeneration of the knee cartilage and increased effusion compared with healthy controls. Ultrasonography is an effective method to detect these changes. However, cartilage degeneration was not found to be associated with disease-related parameters in multiple sclerosis.

The aim of this study was to evaluate blink rate (BR), tear tests and corneal parameters by Scheimpflug imaging and also to clarify the associations between the severity of disease and corneal parameters in patients with Parkinson's disease (PD). Forty patients with PD and 40 healthy subjects were included in this study. All participants underwent a detailed neurological and ophthalmological evaluation. The severity of disease was measured according to Hoehn-Yahr (H-Y) scale. BR was determined for participants. Corneal parameters were measured using Pentacam. Additionally, Schirmer test, tear break-up time (TBUT), corneal fluorescein staining, and Ocular Surface Disease Index (OSDI) scores were assessed. Corneal parameters were significantly different between the patients with PD and healthy controls. The mean central corneal thickness (538.95 ± 30.9 µm versus 557.60 ± 26.6 µm, p = 0.005) was significantly reduced in patients with PD compared to healthy controls. The BR and the values of TBUT and Schirmer test scores were significantly lower in patients with PD than in controls. Also, corneal fluorescein staining and OSDI scores were higher in patients with PD than in controls. The BR was significantly negative correlated with the severity of the disease. Factors related to the corneal thickness were BR, TBUT and Schirmer test (p < 0.05 for all). Corneal thickness may decrease in patients with PD which may be affected by reduced BR and tear dysfunction.

PURPOSE: To evaluate retinal nerve fiber layer (RNFL) thickness in migraine patients with unilateral headache. METHODS: A total of 58 patients diagnosed with migraine headache consistently occurring on the same side and 58 age- and sex-matched healthy subjects were evaluated in this cross-sectional study. RNFL thickness was measured using spectral-domain optical coherence tomography, and the side with the headache was compared with the contralateral side as well as with the results of healthy subjects. RESULTS: The mean patient age was 33.05 ± 8.83 years, and that of the healthy subjects was 31.44 ± 8.64 years (p = 0.32). The mean duration of disease was 10.29 ± 9.03 years. The average and nasal RNFL thicknesses were significantly thinner on the side of headache and on the contralateral side compared to control eyes (p < 0.05, for all). Thinning was higher on the side of the headache compared to the contralateral side; however, this difference was not statistically significant. CONCLUSIONS: The RNFL thicknesses were thinner on the side of the headache compared to the contralateral side in the migraine patients with unilateral headache, but this difference was not statistically significant.

We aimed to evaluate the thicknesses of the retinal nerve fiber layer (RNFL) in patients with cerebral infarction (CI) by using optical coherence tomography. This cross-sectional study evaluated 45 patients with CI (patient group) and 45 healthy subjects (control group). All subjects underwent a complete ophthalmic examination including optical coherence tomography. The average, temporal, nasal, inferior, and superior quadrant RNFL thicknesses and in each of 12 sectors around the optic nerve head were obtained. The side with the infarction was compared to the contralateral side among the patients with cerebral infarction, and their measurements were also compared to those of the control group. Patients who had CI only in the middle cerebral artery (MCA) and posterior cerebral artery (PCA) were included in this study. Correlations between the RNFL thicknesses and infarction features were also evaluated. The mean age of the patients was 61.6 ± 12.4 years, and the mean age of the controls was 59.6 ± 11.8 years (p = 0.65). Of the 45 patients with cerebral infarction, 35 (77.7 %) had infarction in the MCA territory, 10 (22.2 %) had infarction in the PCA territory and the mean duration of the disease was 20.2 ± 29.1 months. The average, superior, inferior, and nasal RNFL thicknesses were significantly thinner in both eyes of the patients with CI than in the eyes of the control group (p < 0.05). The average and inferior RNFL thicknesses were significantly more affected in the ipsilateral eyes than in the contralateral eyes (p < 0.031 and p < 0.006, respectively). The amount of reduction in the RNFL thicknesses was not correlated with the infarction features. Significant thinning of the RNFL in patients with CI may result from transneuronal retrograde degeneration. Optical coherence tomography may provide useful information to confirm the process of trans-synaptic retrograde degeneration.

Multiple sclerosis (MS) is one of the main chronic inflammatory diseases of the central nervous system that causes functional disability in young people. The aim of this study was to investigate the neutrophil-to-lymphocyte ratio (NLR) in patients with MS and the relationship between the NLR and the severity of the disease. One hundred and two MS patients (31 patients were in relapse; 71 patients were in remission) and 56 healthy controls were included. Complete blood counts as well as demographic and clinical data from MS patients were evaluated retrospectively. The NLRs were calculated for all participants and were compared; the cut-off value was also determined for the NLR and Expanded Disability Status Scale (EDSS). MS patients had a significantly higher NLR (p < 0.001) than the control group. The NLR levels were significantly higher in patients who were in relapse than patients in remission (p = 0.039). The cut-off value for the NLR to predict an MS diagnosis and activity were determined to be 2.04 and 3.90, respectively. The NLRs were directly correlated with erythrocyte sedimentation rate levels (r = 0.795, p < 0.001). Logistic regression analysis with dichotomous EDSS score showed that a high NLR was an independent predictor of the progression of disability. The NLR may be a biomarker that has simple, quick, inexpensive and reproducible properties in MS to predict patient's prognosis.

CONTEXT: Migraine is a frequent and disabling chronic neurological condition with complex pathophysiology. Both cigarette smoking and migraine may cause damage to the optic nerve. OBJECTIVE: The primary objective of this study was to investigate the effect of cigarette smoking on retinal nerve fiber layer (RNFL) thickness in patients with migraine. MATERIALS AND METHODS: Eighty-four consecutive patients diagnosed with migraine (34 smokers and 50 nonsmokers) and 66 age- and gender-matched healthy non-smoker controls were enrolled for this observational cross-sectional study. RNFL thickness was measured using spectral-domain optical coherence tomography (OCT) and then RNFL thickness in patients with migraine who smoke was compared to nonsmoking patients with migraine and healthy subjects. RESULTS: The average, superior, nasal and inferior RNFL thicknesses were significantly thinner in patients with migraine compared to the control group (p < 0.001, p = 0.02, p < 0.001 and p = 0.04, respectively). The average and inferior RNFL thicknesses were significantly reduced in smoker patients with migraine compared to the nonsmokers (p = 0.011, p = 0.045, respectively). Nonsmoker patients with migraine had significantly thinner average and nasal RNFL thicknesses than the control group (p = 0.001, p = 0.001, respectively). CONCLUSION: Cigarette smoking may cause significant RNFL thinning in patients with migraine. OCT may be a feasible technique for determination of smoking-induced ocular damage in patients with migraine.

PURPOSE: To evaluate refractive errors in patients with migraine headache and to compare with healthy subjects. MATERIALS AND METHODS: This prospective case-control study includes patients with migraine and age- and sex-matched healthy subjects. Clinical and demographic characteristics of the patients were noted. Detailed ophthalmological examinations were performed containing spherical refractive error, astigmatic refractive error, spherical equivalent (SE), anisometropia, best-corrected visual acuity, intraocular pressure, slit lamp biomicroscopy, fundus examination, axial length, anterior chamber depth, and central corneal thickness. Spectacle use in migraine and control groups was compared. Also, the relationship between refractive components and migraine headache variables was investigated. RESULTS: Seventy-seven migraine patients with mean age of 33.27 ± 8.84 years and 71 healthy subjects with mean age of 31.15 ± 10.45 years were enrolled (p = 0.18). The migraine patients had higher degrees of astigmatic refractive error, SE, and anisometropia when compared with the control subjects (p = 0.01, p = 0.03, p = 0.02, respectively). CONCLUSION: Migraine patients may have higher degrees of astigmatism, SE, and anisometropia. Therefore, they should have ophthalmological examinations regularly to ensure that their refractive errors are appropriately corrected.
