Abstract
Dry eye syndrome (DES) is a tear film disorder caused by increased tear evaporation or decreased production. The heavy workload on the eye and the increased usage of digital screens may decrease blink frequency, leading to an increased evaporation rate and an upsurge in the incidence and severity of DES. This study aims to assess the severity of DES symptoms and the risk factors among university students. A cross-sectional study was conducted at Umm AlQura University to evaluate the severity of DES among students and explore its potential association with digital screen use. Validated questionnaires were used to assess the severity of DES and digital screen usage. The study included 457 participants, of which 13% had symptoms suggestive of severe DES. Furthermore, multiple risk factors had a significant association with the severity of DES, including gender, use of monitor filters, monitor and room brightness, and smoking habits. DES symptoms were prevalent among university students, particularly female students. Although there was no significant association with the duration of screen usage and collage distribution. Other factors however, such as the usage of screen monitors and the brightness of both the monitor and the room, were significantly associated with the severity of DES symptoms.

Abstract
INTRODUCTION To compare the efficacy and safety of a homeopathic eye drop medicinal product (Homeoptic®) with 0.9% sodium hydrochloride eye drops (Larmabak®) in patients with mild-to-moderate dry eye disease (DED). METHODS Prospective, single-masked, observer-blinded, multicentre study on adult patients. Non-inferiority primary endpoint of the relative change between treatment groups in a composite Visual Analogue Scale (VAS) score covering five symptoms of DED, namely pain, itching, sensation of dry eye, impression of foreign body presence and burning, after 30 days of treatment. Details of all Adverse Events (AEs) were recorded and analysed. RESULTS Ninety three patients were randomised to each treatment arm. At Day 30, the mean VAS symptom score was 26.0 ± 18.8 in the Homeoptic® group and 32.8 ± 21.2 Larmabak® group. Homeoptic® was demonstrated to be non-inferior to Larmabak®: the mean treatment difference of -7 being below the 10 mm upper limit of the 95% CI ([-12.9; -1.0]) pre-set as significant. The superiority of Homeoptic® over Larmabak® was then established with detection of a significant difference between the two treatment groups (p = 0.022). Significant differences between the treatment groups in favour of Homeoptic® were also detected in isolated VAS scores for the symptoms dry eye sensation (p = 0.009) and burning (p = 0.004). Results of ocular surface staining tests to estimate corneal and conjunctival damage as well as patient satisfaction were also significantly in favour of Homeoptic®. No new safety concerns were identified. CONCLUSION Homeoptic® is more effective than Larmabak® at relieving the symptoms of DED and constitutes an effective treatment for mild-to-moderate DED.

Abstract
Disease biomarkers in tears are crucial for clinical diagnosis and health monitoring. However, the limited volume of tear samples, low concentration of tear biomarkers, and complex tear composition present challenges for precise testing. We introduce a spot-on testing platform of metal-organic framework (MOF)-based surface-enhanced Raman scattering (SERS) capillary column, which is capable of target molecules selective separation and enrichment for tear biomarkers in situ detection. It consists of Au nanostars for effective SERS signal and a porous MOF shell for separating impurities through molecular sieving effect. This platform allows for simultaneous collection and detection of tear, capturing the disease biomarker malondialdehyde in tears with a 9.38 × 10-9 mol/L limit of detection. Moreover, we designed a hand-held device based on this tubular SERS sensor, successfully diagnosing patients with dry eye disease. This functional capillary column enables noninvasive and rapid diagnosis of biomarkers in biofluids, providing potential for disease diagnosis and healthcare monitoring.

Abstract
PURPOSE In this review, we aimed to investigate the literature on sex-specific prevalence of meibomian gland dysfunction (MGD) and to determine whether women or men are more at risk for MGD. METHODS A search was conducted on PubMed using the terms: (Sex OR Gender OR prevalence) AND (Meibomian gland). RESULTS Twenty-four relevant studies on MGD prevalence were identified, including 10 population-based and 14 hospital-based studies. Among the population-based studies, five studies reported higher rates among men, three studies found no differences, and one study observed higher rates among women. In the hospital-based studies, 10 studies reported no difference, two found higher rates among men, and one found higher among women. In the reviewed literature, there was a considerable variation between studies in terms of quality, sample size, age ranges, diagnostic criteria. CONCLUSIONS While most of the population-based studies suggest a higher prevalence among men, the majority of clinic-based studies show no significant difference. Further research with larger samples and standardized criteria is needed to determine whether men are indeed more susceptible to MGD.

Abstract
PURPOSE As ocular dryness and glaucoma are more prevalent with increasing age, understanding how the tear film affects tonometry is important. The present study aims to understand the impact that changes in the tear film have on intraocular pressure (IOP), corneal hysteresis, and corneal resistance factor measurements. METHODS Cross-sectional research was conducted and 37 patients were assessed. The tear film lipid layer and the non-invasive break-up time (NIBUT) were evaluated using the Tearscope Plus (Keeler, Windsor, UK). Dry eye symptoms were evaluated using the Ocular Surface Disease Index (OSDI) questionnaire. IOP was measured using rebound tonometry and the Ocular Response Analyzer (ORA, Reichert). Corneal biomechanical properties were measured using ORA. RESULTS It was found that an increase in the IOP measured with the iCare was directly correlated with the subclass that evaluated symptomatology associated with environmental factors (r = 0.414, p<0.05, Spearman). Goldmann-correlated IOP (IOPg) and Corneal-compensated IOP (IOPcc) values were statistically significantly different between the various interferometric patterns (p<0.05). It was also found that an increase in the corneal biomechanical properties measured with ORA was directly correlated with the overall scores obtained when using the OSDI and some of its subclasses. CONCLUSIONS Tear film interferometric patterns were shown to have some impact on the IOP measured using ORA. The IOP measured with iCare seems to be related to the symptomatology obtained from OSDI. Corneal biomechanical properties were related to the OSDI total score and some of its subclasses. An increase in symptomatology was associated with an increase in the measured biomechanical properties of the cornea.

Abstract
PURPOSE We aimed to describe changes in the geographic distribution of self-reported visual impairment (VI) over the last decade (2010-2019) in the U.S. METHODS Our study was an analysis of publicly available data collected between 2010 and 2019 from the Census Bureau American Community Survey. RESULTS The mean overall prevalence of self-reported VI from 2010 to 2019 was 2.31% in the United States, and there was a significant increase in VI over the past decade from 2.25% in 2010-2014 to 2.37% in 2015-2019 (p < .001). VI was significantly higher in rural counties (3.58%), compared to urban (3.10%) or metropolitan counties (2.18%) (p < .001). In terms of geographic region, the South of the United States had the highest rate of VI (2.63%) (p < .001). For age groups > 17-years-old in the 2010-2019 data, women had higher rates of VI compared to men. CONCLUSIONS Prevalence of self-reported visual impairment has risen and disproportionately affects certain communities. This includes individuals living in the South, in rural counties, and women.

Abstract
PURPOSE To investigate the effects of humidity and temperature on dry eye disease (DED). METHODS A retrospective, clinic-based study was conducted on DED patients undergoing dry eye treatment. Patients were followed up at least twice, and symptoms and signs were evaluated using the Symptoms Assessment Questionnaire in Dry Eye (SANDE) score, tear secretion, tear film breakup time (TBUT), ocular staining score, and tear osmolarity. Mean humidity and temperature values for 1 week before ocular examinations were used as the environmental exposure level. The relationship between humidity and temperature, with DED clinical parameters was analyzed in single- and multi-environmental factor models. RESULTS The study included 33 patients with a mean age of 53.9 ± 12.2 years. The low humidity group showed significantly higher SANDE scores (p = 0.023) and tear osmolarity (p = 0.008), and the low temperature group had higher SANDE scores (p = 0.004), ocular staining scores (p = 0.036), and tear osmolarity (p < 0.001). In the linear mixed model, single factor analysis showed that an increase in humidity resulted in decreased SANDE scores (p = 0.043), and an increase in temperature led to a decrease in SANDE score (p = 0.007), ocular staining score (p = 0.007), and tear osmolarity (p = 0.012). In the multifactor analysis, changes in humidity had no significant effect on dry eye parameters, but an increase in temperature was significantly correlated with decreased SANDE score (p = 0.026), ocular staining score (p = 0.024), and tear osmolarity (p = 0.002). CONCLUSIONS Lower temperature led to aggravated symptoms and signs of DED and the effect of temperature on DED was more pronounced than humidity. Tear osmolarity was the most sensitive clinical parameter to be affected by climate factors in DED patients.

Abstract
PURPOSE The Ocular Surface Disease Index (OSDI) is the most frequently used dry eye disease (DED) questionnaire, and the Symptom Assessment iN Dry Eye (SANDE) is the simplest and quickest to apply. We analyze the correlation and level of agreement between these two questionnaires in a large DED heterogeneous population to evaluate their performance and potential interchangeability. METHODS Prospective, multicenter longitudinal survey-based study performed on patients diagnosed with DED by 99 ophthalmologists from 20/32 Mexican states. Questionnaires were applied in two consecutive visits to analyze the correlation between OSDI and SANDE to evaluate patients with DED clinically. Level of agreement was evaluated with Bland-Altman analysis, and internal consistency of instruments was evaluated individually and combined with Cronbach's alpha index. RESULTS 3421 patients studied: 1996 (58.3%) women and 1425 (41.7%) men, aged 49.5 ± 15.4 years; 995 (29.1%) patients had aqueous-deficient, 1086 (31.7%) evaporative, and 1340 (39.2%) mixed DED subtypes. Normalized baseline scores were 53.7 (OSDI) and 54.1 (SANDE). After 36.3 ± 24.4 days between visits, scores were reduced to 25.2 (OSDI) and 21.8 (SANDE) points (p < .001). A positive correlation between questionnaires was found at baseline (R = 0.592; p < .001), follow-up (R = 0.543; p < .001) and change between visits (R = 0.630; p < .001). Using both questionnaires together improved the overall reliability of symptom evaluation at baseline (α = 0.7), follow-up (α = 0.7), and both (α = 0.7), compared to individual application (OSDI α = 0.5, SANDE α = 0.6)-the same improvements applied to all DED subtypes. Bland-Altman analysis revealed a differential bias of -0.41% at baseline and +3.6% at follow-up visits between OSDI and SANDE. CONCLUSIONS We validated the correlation (high precision) between questionnaires in a large-scale population, demonstrating improved reliability (high accuracy) in evaluating DED when used together, challenging their interchangeable use. These results open a venue to improve recommendations toward a more precise and accurate diagnostic and therapeutic evaluation of DED by using OSDI and SANDE concurrently.

Abstract
BACKGROUND Patients with Diabetes mellitus (DM) are at risk of developing dry eye disease (DED). We investigated routine laboratory parameters in patients with type 2 DM (T2D) and T2D-DED to identify potential inflammatory markers. METHODS A retrospective study of 241 randomly selected patients (30 DED non-diabetic, 120 T2D, and 91 with T2D-DED). The neutrophil-to-lymphocyte ratios (NLR), CRP-to-albumin ratios (CAR), and the glycosylated haemoglobin A1c (HbA1c) results were correlated between groups. RESULTS The NLR and HbA1c were significantly higher in the T2D-DED group (p≤0.001 and 0.0001, respectively) when compared with T2D and DED non-diabetic groups. CAR was insignificantly high in the three groups (p=0.192). A positive correlation was identified between CAR and NLR in T2D-DED patients (p= 0.008). CONCLUSION In T2D-DED patients, NLR was significantly high and positively correlate with CAR. These results predicate diabetes with dry eye complications, and biomarker-mediated inflammation may have important roles in DED pathogenesis.

There is a significant unmet need for therapeutics to treat ocular surface barrier damage, also called epitheliopathy, due to dry eye and related diseases. We recently reported that the natural tear glycoprotein CLU (clusterin), a molecular chaperone and matrix metalloproteinase inhibitor, seals and heals epitheliopathy in mice subjected to desiccating stress in a model of aqueous-deficient/evaporative dry eye. Here we investigated CLU sealing using a second model with features of ophthalmic preservative-induced dry eye. The ocular surface was stressed by topical application of the ophthalmic preservative benzalkonium chloride (BAC). Then eyes were treated with CLU and sealing was evaluated immediately by quantification of clinical dye uptake. A commercial recombinant form of human CLU (rhCLU), as well as an rhCLU form produced in our laboratory, designed to be compatible with U.S. Food and Drug Administration guidelines on current Good Manufacturing Practices (cGMP), were as effective as natural plasma-derived human CLU (pCLU) in sealing the damaged ocular surface barrier. In contrast, two other proteins found in tears: TIMP1 and LCN1 (tear lipocalin), exhibited no sealing activity. The efficacy and selectivity of rhCLU for sealing of the damaged ocular surface epithelial barrier suggests that it could be of therapeutic value in treating BAC-induced epitheliopathy and related diseases.

Sanchez V, Cohen NK, Felix E, Galor A. Factors affecting the prevalence, severity, and characteristics of ocular surface pain. EXPERT REVIEW OF OPHTHALMOLOGY 2022; 18:19-32. [PMID: 37009062 PMCID: PMC10062703 DOI: 10.1080/17469899.2023.2157813] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Accepted: 12/06/2022] [Indexed: 12/13/2022]
Abstract
Introduction Ocular surface pain has been traditionally lumped under the umbrella term "dry eye" (DE) but is now understood as its own entity and can occur in the absence or presence of tear dysfunction. Identifying patients at risk for the development of chronic ocular surface pain, and factors contributing to its severity are important in providing precision medicine to patients. Areas covered In this review, we discuss factors linked to the presence and severity of ocular surface pain, including eye related features, systemic characteristics, and environmental findings. We discuss corneal nerves, whose anatomic and functional integrity can be characterized through in vivo confocal microscopy images and testing of corneal sensitivity. We review systemic diseases that are co-morbid with ocular surface pain, including physical and mental health diagnoses. Finally, we identify environmental contributors, including air pollution, previous surgeries, and medications, associated with ocular surface pain. Expert opinion Intrinsic and extrinsic factors contribute to ocular surface pain and must be considered when evaluating an individual patient. These factors can inform the suspected etiology of the pain, and guide management decisions such as tear replacement or medications targeting nerve pain.

[PMID: 35322930 PMCID: PMC9790390 DOI: 10.1111/aos.15130] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Revised: 03/04/2022] [Accepted: 03/12/2022] [Indexed: 12/30/2022]
Abstract
PURPOSE The aim of this study was to describe the clinical ocular surface characteristics in a population-based sample of Finnish elderly people. METHODS This cross-sectional study included 601 subjects (335 females, 266 males) born between the years 1933-1956 and living in Savitaipale, Finland. Ocular surface health was evaluated using a comprehensive set of diagnostic tests. Previous dry eye (DE) diagnosis and history of drug treatment of DE were also recorded. Differences between sexes were estimated with Wilcoxon rank sum test and Fisher's exact test. RESULTS Overall, 10% and 33% of people displayed signs of DE and ocular surface disease (OSD), respectively, and 30% had been previously diagnosed with DE and 36% used some form of drugs for DE. Men displayed more severe signs of meibomian gland dysfunction, blepharitis and conjunctival redness (p < 0.001), while women had higher scores in corneal staining (p = 0.005) and OSD Index (p < 0.001). CONCLUSION Signs of OSD and DE are common among the Finnish elderly population. However, the diagnosis is affected by the diagnostic criteria used and significant differences exist between sexes. Although women were more frequently diagnosed with DE and OSD and experienced more ocular surface irritation, men had more often lid and meibomian gland-related issues. The current diagnostic criteria of DE pose a risk of misclassifying men, who commonly display less severe symptoms in comparison with women yet exhibit more severe clinical signs associated especially with the lid margin.

Abstract
OBJECTIVE Distinguish between EDE severity levels by analysing the MGLA, conjunctival hyperemia and corneal staining. METHODS One hundred participants were recruited based on OSDI, TO, TFBUT, TMH, and LLP to be categorised as healthy (Group 1) or EDE (Group 2). Group 2 was divided into Group 2A (mild symptoms), 2B (moderate), and 2C (severe). MGLA, conjunctival hyperemia, and corneal staining were measured. RESULTS Positive correlation between MGLA, conjunctival hyperemia, and corneal staining were found (all r ≥ 0.221, p ≤ 0.027). Significant differences were found: MGLA between Group 1 vs. 2C and 2C vs. 2A or 2B; conjunctival hyperemia between Group 1 vs. 2A, 2B or 2C; corneal staining between Group 1 vs. 2B or 2C and 2A vs. 2B or 2C (all p ≤ 0.049). CONCLUSION Severe EDE participants have higher MGLA, conjunctival hyperemia, and corneal staining values than healthy, mild, or moderate EDE participants.
