Abstract
Primary Sjogren's syndrome (pSS) is often concomitant with fibromyalgia (FM). Salivary gland sonography aids in the diagnosis of pSS. We aimed to discover, in primary FM patients, the presence of pSS in undiagnosed patients through salivary gland sonography. We prospectively recruited 42 primary FM patients. FM symptoms were evaluated based on the revised Fibromyalgia Impact Questionnaire (FIQR). Salivary gland sonography was performed. Patients with positive findings underwent salivary gland biopsy. Comparisons were undertaken using the Mann-Whitney U tests and Chi-squared test. In primary FM patients, the prevalence of dry eye was 83%, and dry mouth was 90%. The salivary gland sonographic score did not differ between patients with and without dry eye/mouth. One patient with a positive finding at salivary gland sonography had a positive result of salivary gland biopsy. In the other four patients who received salivary gland biopsy, despite negative findings in salivary gland sonography, only one had a positive result of salivary gland biopsy. To be noted, scores evaluated by salivary gland sonography were negatively associated with levels of pain (rho = -0.360, p= 0.023) and levels of sleep quality (rho = -0.447, p = 0.004). Our pilot study demonstrated the potential of salivary gland biopsy in detecting undiagnosed pSS in primary FM patients.

Ketenci S, Uzuner B, Durmuş D, Polat M. Frequency of idiopathic intracranial hypertension with ultrasound in patients with fibromyalgia: Relation with function, central sensitization, and neuropathic pain. Int J Rheum Dis 2024; 27:e15066. [PMID: 38334253 DOI: 10.1111/1756-185x.15066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 01/14/2024] [Accepted: 01/22/2024] [Indexed: 02/10/2024]
Abstract
OBJECTIVE The purpose of this study was to evaluate the prevalence of idiopathic intracranial hypertension (IIH) in fibromyalgia (FMS) patients by utilizing ultrasound to measure the optic nerve sheath diameter (ONSD), a marker of elevated intracranial pressure and also to investigate the relationship with function, fatigue, quality of life (QOL), central sensitization (CS) and neuropathic pain. METHODS The study encompassed 80 female FMS patients and 75 healthy controls. Ultrasound was employed to measure the average ONSD in both groups. Conditions potentially elevating intracranial pressure were ruled out following neurological assessments. Pain (via visual analog scale, VAS), function (revised Fibromyalgia Impact Questionnaire, r-FIQ), QOL (Short Form-36, SF-36), fatigue (fatigue severity scale, FACIT), CS (Central Sensitization Scale), and neuropathic pain (Douleur Neuropathique-4) were evaluated. RESULTS The average ONSD was significantly higher in the patient group than the control group. Patients with ONSD >5.5 mm consistent with IIH were categorized as Group 1 (n = 54, 67.5%), while those with a diameter of 5.5 mm and below-formed Group 2. VAS pain (p = .033) and FIQ-R scores (p = .033) were significantly higher in Group 1 than Group 2. Headache was found more common in Group 1. CONCLUSION This study unveils a substantial occurrence (67.5%) of IIH in FMS patients, suggesting shared pathophysiological mechanisms contributing to symptoms like fatigue, headache, and cognitive dysfunction. Additionally, these findings implicate heightened functional impairment, CS, headache, and fatigue in FMS patients with IIH.

Abstract
PURPOSE To estimate the risk of incidence of optic neuritis and identify the high-risk group among patients with fibromyalgia (FM). DESIGN Population-based cohort study. METHODS A nationwide, population-based study was conducted using data from the Korean National Health Claims database from 2012 to 2021. This study included all the patients with FM from the entire South Korean population aged 20-79 years (FM group). Moreover, those with pain but not diagnosed with FM were considered as the non-FM group. A cohort was established by classifying it into the FM and non-FM groups during the recruitment period. A log-rank analysis was used to compare the risk of optic neuritis incidence between the FM group and non-FM group. Cox proportional hazards regression analysis was performed to calculate the adjusted hazard ratio (HR). The cohort was analyzed by stratifying according to age and sex. RESULTS The FM and non-FM groups included 479,892 and 479,892 participants, respectively. The incidence rate of optic neuritis was 35.65/100,000 person-years in the FM group; the HR was significantly higher in the FM group than in the non-FM group (HR 2.11, 95% CI 1.84-2.41; P < .001). The mean interval between the onset of FM and incident optic neuritis was 2.4 ± 1.8 years. The risk increased significantly in men aged 60-79 years (HR 3.37, 95% CI 2.54-4.48) and in women aged 20-39 years (HR 2.07, 95% CI 1.38-3.22). CONCLUSION We quantified the risk of optic neuritis through a long-term follow-up, which could contribute to understanding the pathophysiology and estimating the general health care burden associated with FM in a practical setting. Great attention should be paid to its risk in older men and younger women.

Abstract
Purpose The purpose of this study was to introduce a novel dry eye rat model induced by aerosol exposure of particulate matter (PM). Methods A total of 30 female Sprague Dawley (SD) rats divided into 3 groups: the control group, the low-level exposed group, and the high-level exposed group. The rats in the experience groups were directly exposed to PM samples in the exposure chamber over 14 days. The clinical observation, including tear volume, corneal fluorescein staining, breakup time (BUT), inflammation index, corneal irregularity score, and corneal confocal microscopy. Eyeballs were collected on day 14 for hematoxylin and eosin (H&E) staining and PAS staining. TUNEL assay, CD45, and Ki67 immunostaining was performed and corneal ultrastructural changes were detected by electron microscopy. IL-1β, TNF-α, IFN-γ, and NF-κB Western blot analysis were used to observe the possible pathogenesis. Results In the PM-treated groups, the number of layers in the corneal epithelium and corneal nerve fiber length were significantly decreased compared with that of the control group. The number of corneal epithelial microvilli and chondriosome/desmosomes were drastically reduced in PM-treated groups. Confocal microscopy and CD45 immunohistochemistry showed inflammatory cell infiltration in the PM-treated groups. PM caused apoptosis of corneal and conjunctival epithelial cells while leading to abnormal epithelial cell proliferation, meanwhile, conjunctival goblet cells in the PM-treated group were also significantly reduced. PM significantly increased the levels of IL-1β, TNF-α, IFN-γ, and p-NF-κB-p65 in the cornea. Conclusions Aerosol exposure of PM can reduce the stability of tear film and cause the change of ocular surface, which is similar to the performance of human dry eye, suggesting a novel animal model of dry eye.

Ocular manifestations and biomarkers of Gulf War Illness in US veterans. Sci Rep 2021; 11:6548.

Abstract
Gulf War Illness (GWI) is a multisystem disease with variable presentations, making diagnosis difficult. Non-invasive biomarkers would aid in disease diagnosis. We hypothesized that the eye could serve as a biomarker for GWI. We performed a retrospective case–control study using a sample of 1246 patients seen during a 5-month period in an optometry clinic. We identified veterans who were active duty during the Gulf War Era and either had a questionnaire-based diagnosis of GWI (cases) or did not (controls). Medical records were reviewed for eye and medical co-morbidities, medication use, and retinal macular and nerve fiber layer (NFL) thicknesses based on optical coherence tomography (OCT) images. Compared to controls (n = 85), individuals with GWI (n = 60) had a higher frequency of dry eye symptoms (50% vs 32.9%, p = 0.039). Multivariable analysis revealed average retinal NFL thickness (odds ratio; OR = 0.95), cup-to-disc ratio (OR = 0.005), age (OR = 0.82), and PTSD (OR = 20.5) were predictors of a GWI diagnosis. We conclude that GWI is associated with dry eye symptoms and RNFL thinning may serve as a biomarker for disease.

Abstract
Fibromyalgia is a chronic, widespread pain syndrome of unclear etiology characterized by fatigue, sleeping problems, cognitive disorders, somatic complaints, and severe pain in parts of the body at the time of physical activity, with no laboratory findings specific to the disease or diagnostic tests. Fibromyalgia can be associated with ocular symptoms (foreign body sensation, irritation) and visual disturbances (blurred vision), coexisting with dry eye syndrome and reduced corneal sensitivity. Cases of scleritis, including the necrotizing form, accompanying fibromyalgia have been reported. Changes in the eye may contribute to the pathogenesis of fibromyalgia. Research shows the choroid to be significantly thinner in patients with fibromyalgia, revealing changes in optic disc perfusion and a decreased retinal nerve fiber layer thickness. There are also thin corneal stromal nerves with diminished sub-basal plexus nerve density. Pathological changes and functional abnormalities of small nerve fibers are observed in patients with fibromyalgia. Corneal confocal bio-microscopy is a new noninvasive method to evaluate small nerve fiber morphology, serving as an alternative for skin biopsies, and reveals new possibilities in diagnostics and finding innovative therapies for this disease. Fibromyalgia remains a challenge for ophthalmologists, and further studies are required to evaluate ocular involvement. It may be that future diagnostic criteria for fibromyalgia will contain ophthalmic examination modalities. Observed ocular changes and their pathomechanisms may constitute new targets for therapy to improve the quality of life of patients with fibromyalgia.

Abstract
PURPOSE Our aim was to summarize key aspects of the pathomechanism and the ocular involvements of rheumatic and systemic autoimmune diseases. METHODS Apart from a paper in French (Morax V, Ann Oculist 109:368-370, 1893), all papers referred to in this article were published in English. All the materials were peer-reviewed full-text papers, letters, reviews, or book chapters obtained through a literature search of the PubMed database using the keywords ocular manifestations; pathogenesis; systemic inflammatory rheumatic diseases; rheumatoid arthritis; osteoarthritis; fibromyalgia; systemic lupus erythematosus; seronegative spondyloarthritis; ankylosing spondylitis; reactive arthritis; enteropathic arthritis; psoriatic arthritis; systemic sclerosis; polymyalgia rheumatica and covering all years available. Some statements articulated in this paper reflect the clinical experience of the authors in their tertiary-referral center. RESULTS Ophthalmic disorders are categorized by anatomical subgroups in all rheumatic diseases. The most common ocular manifestations are diverse types of inflammations of different tissues and dry eye disease (DED). CONCLUSION The eye could be a responsive marker for the onset or aggravation of an immune reactivation in many rheumatic diseases, furthermore, ocular findings can antedate the diagnosis of the underlying rheumatic disease. By recognizing ocular manifestations of systemic rheumatic diseases it might be possible to avoid or at least delay many long term sequelae.

Abstract
Dry eye disease (DED) has become common on a global scale in recent years. There is a wide prevalence of DED in different countries based on various ethnicities and environment. DED is a multifactorial ocular disorder. In addition to advanced age and gender, such factors as living at high altitude, smoking, pterygium, prolonged use of consumer electronics or overingesting of caffeine or multivitamins are considered to be the major risk factors of DED. We report the DED epidemiology in Taiwan firstly in this article. According to the pathophysiological factors and changes inthe composition of the tear film in DED, it can be categorized into several subtypes, including lipid anomaly dry eye, aqueous tear deficiency, allergic and toxic dry eye among others. Each subtype has its own cause and disease management; therefore, it is important for ophthalmologists to identify the type through literature review and investigation. The management of DED, relies not only on traditional medications such as artificial tears, gels and ointments, but also newer treatment options such as acupuncture, SYL1001, and nanomedicine therapy. We also conducted a comprehensive literature review including common subtypes and treatment of DED. Clearly, more clinical trials are needed to assess the efficacy and safety of the various treatments and common subtypes of DED.

Abstract
BACKGROUND To investigate the incidence and prevalence of dry eye disease (DED) in Taiwan and to explore its potential risk factors. METHODS Population-based longitudinal data from 2000 to 2013 based on Taiwan National Health Insurance Research Database were used in this study. To explore potential risks factor of interest, patients who had DED diagnosis before the exposure were excluded. Each patient from the exposure and his/her matched non-exposure controls were followed until either the diagnosis of DED or censorship. Kaplan-Meier method was used to compare the hazard of DED between cohorts. Stratified Cox proportional hazard models were applied to estimate the adjusted effect. RESULTS The age-adjusted prevalence for men and women were 6.81% and 16.16%, respectively. The age-gender rate of the same period was 549 per 105 person-years. The propensity-adjusted hazard ratio of DED is 1.816 for the presbyopia versus non-presbyopia (with 95% CI = [1.737, 1.897] with p value < 0.0001). CONCLUSIONS The DED incidence for women peaked at age 50-74, while that for men peaked at age ≧ 75. The incidence in young people seems stable both for women and for men. While exploring the factors of DED, there is a significant association between presbyopia and DED even after matching age/gender and comorbidity conditions. Further clinical studies are needed to justify whether the corrective refractive treatment such as presbyopic glasses to treat the frequently hyperopic status of these patients could be beneficial to both dry eye and presbyopic condition.

Abstract
In this study, we explored the effects of particulate matter 2.5 (PM2.5) eye drops on the ocular surface structure and tear function in mice and established a novel animal model for dry eye research. We found that, following treatment with PM2.5, the tear volume and, the tear film break-up time showed statistical differences at each time point (P < 0.05). The FL score of the PM2.5-treated group was higher than that of others (P < 0.05). The average number of corneal epithelial layer cells in groups A and B was significantly lower than that in group C (P < 0.05). Scanning electron microscopy and transmission electron microscopy revealed that the number of corneal epithelial microvilli and corneal desmosomes was drastically reduced in group C. PM2.5 induced apoptosis in the corneal superficial and basal epithelium and led to abnormal differentiation and proliferation of the ocular surface with higher expression levels of Ki67 and a reduced number of goblet cells in the conjunctival fornix in group C. PM2.5 significantly increased the levels of TNF-α, NF-κB p65 (phospho S536), and NF-κB in the cornea. Thus, the topical administration of PM2.5 in mice induces ocular surface changes that are similar to those of dry eye in humans, representing a novel model of dry eye.

Abstract
PURPOSE Idiopathic intracranial hypertension (IICH) is a condition characterized by raised intracranial pressure (ICP), and its diagnosis is established when the opening pressure measured during a lumbar puncture is elevated >20 cm H2O in nonobese patients or >25 cm H2O in obese patients. Papilledema is caused by forced filling of the optic nerve sheath with cerebrospinal fluid (CSF). Other common but underappreciated symptoms of IICH are neck pain, back pain, and radicular pain in the arms and legs resulting from associated increased spinal pressure and forced filling of the spinal nerves with CSF. Widespread pain and also several other characteristics of IICH share notable similarities with characteristics of fibromyalgia (FM) and chronic fatigue syndrome (CFS), two overlapping chronic pain conditions. The aim of this review was to compare literature data regarding the characteristics of IICH, FM, and CFS and to link the shared data to an apparent underlying physiopathology, that is, increased ICP. METHODS Data in the literature regarding these three conditions were compared and linked to the hypothesis of the shared underlying physiopathology of increased cerebrospinal pressure. RESULTS The shared characteristics of IICH, FM, and CFS that can be caused by increased ICP include headaches, fatigue, cognitive impairment, loss of gray matter, involvement of cranial nerves, and overload of the lymphatic olfactory pathway. Increased pressure in the spinal canal and in peripheral nerve root sheaths causes widespread pain, weakness in the arms and legs, walking difficulties (ataxia), and bladder, bowel, and sphincter symptoms. Additionally, IICH, FM, and CFS are frequently associated with sympathetic overactivity symptoms and obesity. These conditions share a strong female predominance and are frequently associated with Ehlers-Danlos syndrome. CONCLUSION IICH, FM, and CFS share a large variety of symptoms that might all be explained by the same pathophysiology of increased cerebrospinal pressure.

Abstract
Background and Aim The clinical association between dry eye syndrome (DES) and chronic fatigue syndrome (CFS) remain unclear with less evidences. We aimed to investigate the relationship between CFS and DES using a national insurance and prospective cohort study. Methods Data from the Longitudinal Health Insurance Database 2000 was applied to estimate the incidence of CFS among patients with DES, and their age- and sex-matched controls without DES over a long-term follow-up period. All participants were CFS free at baseline, before the interval (2005-2007), but were later diagnosed with CFS. DES patients and its relative matched controls were excluded prevalent CFS before the same interval. Results We identified 884 patients with DES and 3,536 matched controls in baseline and estimated the hazard ratios for incident CFS in the follow-up period. Patients with DES had a 2.08-fold considerably increasing risk of developing CFS, compared to non-DES group. An elevated risk of developing CFS remained (1.61-fold risk) even after adjusting for age, sex, and comorbidities. There was a presence of increasing risk in DES-related CFS when CFS-related comorbidities existing (adjusted hazard ratio, 1.98, 95% confidence interval, 1.19-3.29; p < 0.01). The subsequent risk for CFS between DES and non-DES patients was significant increased with three or more annual medical visits, the adjusted risk for CFS was 4.88-fold risk (95% CI, 2.26-10.58, p < 0.001). Conclusion We recommended that physicians should be aware of the increased risk of CFS among DES patients and adequately assess the health impacts among these patients.

Abstract
One of the most compelling features of dry eye disease (DED) is that it occurs more frequently in women than men. In fact, the female sex is a significant risk factor for the development of DED. This sex-related difference in DED prevalence is attributed in large part to the effects of sex steroids (e.g. androgens, estrogens), hypothalamic-pituitary hormones, glucocorticoids, insulin, insulin-like growth factor 1 and thyroid hormones, as well as to the sex chromosome complement, sex-specific autosomal factors and epigenetics (e.g. microRNAs). In addition to sex, gender also appears to be a risk factor for DED. "Gender" and "sex" are words that are often used interchangeably, but they have distinct meanings. "Gender" refers to a person's self-representation as a man or woman, whereas "sex" distinguishes males and females based on their biological characteristics. Both gender and sex affect DED risk, presentation of the disease, immune responses, pain, care-seeking behaviors, service utilization, and myriad other facets of eye health. Overall, sex, gender and hormones play a major role in the regulation of ocular surface and adnexal tissues, and in the difference in DED prevalence between women and men. The purpose of this Subcommittee report is to review and critique the nature of this role, as well as to recommend areas for future research to advance our understanding of the interrelationships between sex, gender, hormones and DED.

Abstract
The subcommittee reviewed the prevalence, incidence, risk factors, natural history, morbidity and questionnaires reported in epidemiological studies of dry eye disease (DED). A meta-analysis of published prevalence data estimated the impact of age and sex. Global mapping of prevalence was undertaken. The prevalence of DED ranged from 5 to 50%. The prevalence of signs was higher and more variable than symptoms. There were limited prevalence studies in youth and in populations south of the equator. The meta-analysis confirmed that prevalence increases with age, however signs showed a greater increase per decade than symptoms. Women have a higher prevalence of DED than men, although differences become significant only with age. Risk factors were categorized as modifiable/non-modifiable, and as consistent, probable or inconclusive. Asian ethnicity was a mostly consistent risk factor. The economic burden and impact of DED on vision, quality of life, work productivity, psychological and physical impact of pain, are considerable, particularly costs due to reduced work productivity. Questionnaires used to evaluate DED vary in their utility. Future research should establish the prevalence of disease of varying severity, the incidence in different populations and potential risk factors such as youth and digital device usage. Geospatial mapping might elucidate the impact of climate, environment and socioeconomic factors. Given the limited study of the natural history of treated and untreated DED, this remains an important area for future research.

Abstract
OBJECTIVE Previous studies have suggested an association between dry eye and migraine. In a busy ophthalmologist clinic, quick identification of dry eye in migraine sufferers may improve their quality of life. Tear osmolarity is an objective and reliable tool for diagnosing dry eye. It has not been investigated in any population with migraine. Using tear osmolarity and questionnaires, we aimed to explore the relationship between dry eye and clinical symptoms in patients with migraine. DESIGN Prospective cross-sectional study. PARTICIPANTS Thirty-four adults with migraine sequentially recruited from a single neurologist's practice. METHODS Patients were assessed for subjective and objective signs of migraine and dry eye by using the Migraine Disability Assessment Score, the Ocular Surface Disease Index, and tear osmolarity (TearLab). Headache characteristics were compared by using χ2, Fisher's exact, and Mann-Whitney U tests. Osmolarity scores were compared with scores for headache features. RESULTS Median age of patients was 38 years, and 76.5% were females. Severe migraine disability was reported in 75.6%, and 34.5% reported moderate to severe dry eye symptoms. Objectively, 49.5% had evidence of dry eye, significantly higher than the 20% recognized in the general population (p < 0.0001). Aura was found to occur more frequently with dry eye (43.8% vs 5.9%; p = 0.02). Those with daily headaches were also more likely to have higher tear osmolarity with marginal significance (median osmolarity 310 mOsm/L vs 299 mOsm/L; p = 0.08). CONCLUSIONS Patients with migraine, especially those with aura, appear more likely to have dry eye, as indicated by tear osmolarity. Tear osmolarity may also be greater in those who suffer from daily headaches.
