Abstract
ABSTRACT Dry eye is an increasingly common ocular condition with significant impact on quality of life due to eye discomfort and blurred vision complaints. In addition, the financial burden of dry eye on both patients and society is substantial. Although there has been a recent explosion of research in the field since 2002 with the approval of the first prescription topical treatment (Restasis, Allergan Inc, Irvine CA), dry eye lags behind other ophthalmic conditions where clinically meaningful outcome measures are closely tied with the metrics by which their therapeutics are evaluated. Unfortunately, current practice is such that physicians largely rely on patient symptoms to evaluate dry eye, and these do not always correlate with objective ocular surface and tear film parameters. In patients with severe dry eye, the patient-reported symptoms are likely dampened because of the neurotrophic state of the ocular surface, which accompanies any long-standing inflammatory ocular condition. Therefore, staining of the corneal and conjunctival surface using vital dyes is an invaluable dry eye test to provide information normally not visible during routine slit-lamp examination. The landmark article by Bron, Evans, and Smith published in Cornea in 2003 provides excellent guidance to clinicians to highlight and quantify ocular surface parameters in patients with dry eye. Validation studies correlating conjunctival or corneal staining with tangible quality-of-life parameters and metrics to measure those are needed to verify ocular surface staining as a clinically meaningful dry eye outcome to be used in clinical practice and clinical trials.

Abstract
SIGNIFICANCE Dry eye disease causes ocular pain, blurred vision, reduced visual quality of life, and reduced workplace performance. This disease is underreported and underdiagnosed despite being highly prevalent in optometric care. PURPOSE This study aimed to explore the vision-related quality of life of patients with dry eye disease and the potential benefits of screening for dry eye disease in Norwegian optometric practice. METHODS This study adopted an observational, prospective, cross-sectional design. All patients between 18 and 70 years of age who were examined between June 8 and July 5, 2018, at Erøy Optikk, Kristiansand, Norway, were invited to participate. Dry eye disease was assessed according to Tear Film & Ocular Surface Society International Dry Eye Workshop II report recommendations. Vision-related quality of life was assessed with the National Eye Institute 25-item Visual Function Questionnaire. RESULTS Forty-nine patients participated in the study; 29 (59%) were female, and 29 (59%) had dry eye disease. The patients with dry eye disease reported significantly more ocular pain and (vision-specific) role difficulties than the patients without dry eye disease. After adjusting for age, sex, and habitual visual acuity, dry eye disease was found to be an independent predictor of both ocular pain ( r2 = 0.328, P = .001) and (vision-specific) role difficulties ( r2 = 0.240, P = .02). Both habitual visual acuity and dry eye disease were predictors of reduced general vision, a reduced score for near activity and reduced (vision-specific) mental health. CONCLUSIONS Dry eye disease was an independent predictor of ocular pain (vision-specific), role difficulties, and reduced general vision, near vision, and (vision-specific) mental health. Optometrists should consider dry eye disease as a cause of reduced vision and quality of vision. Furthermore, we propose that screening for dry eye disease in Norwegian optometric practice can promote better vision and health among patients.

Abstract
Vision loss from advanced glaucoma is currently irreversible and impairs functional visual ability to effectively perform everyday tasks in a number of distinct functional domains. Vision rehabilitation strategies have been demonstrated to be effective in low vision populations and should be utilized in persons with advanced glaucoma to reduce disability and improve quality of life. Initial challenges to rehabilitation include an incomplete understanding of vision rehabilitation by the physician and patient, motivation to integrate rehabilitation into the plan of care, and availability of suitable providers to deliver this care. Physicians, working with well-trained vision rehabilitation providers can maximize function in important visual domains customized to the patient based on their needs, specific complaints, severity/pattern of visual damage, and comorbidities. Potential rehabilitative strategies to be considered for reading impairment include spectacle correction, visual assistive equipment, and sensory substitution, while potential strategies to facilitate driving in those deemed safe to do so include refractive correction, lens design, building confidence, restriction of driving to safer conditions, and avoiding situations where cognitive load is high. Mobility is frequently disrupted in advanced glaucoma, and can be addressed through careful distance refraction, behavior modification, home modification, mobility aids, walking assistance (i.e., sighted guide techniques), and smartphone/wearable technologies. Visual motor complaints are best addressed through optimization of lighting/contrast, sensory substitution, IADL training, and education. Special rehabilitative concerns may arise in children, where plans must be coordinated with schools, and working adults, where patients should be aware of their rights to accommodations to facilitate specific job tasks.

Abstract
PurposeTo investigate binocular dynamic visual acuity (DVA) for patients with dry eye disease (DED).MethodsThe prospective study included DED patients. The binocular DVA at 40 and 80 degrees per second (dps), Ocular Surface Disease Index (OSDI), tear meniscus height (TMH), tear film break-up time first (TBUTF), corneal fluorescein staining (CFS), eyelid margin abnormalities and meibomian gland (MG) abnormalities morphology and function were evaluated. A deep learning model was applied to quantify the MG area proportion. The correlation between DVA and DED parameters was analyzed.ResultsA total of 73 DED patients were enrolled. The age, OSDI, CFS, MG expressibility, secretion quality, and eyelid margin abnormalities were significantly positively correlated with the DVA for 40 and 80 dps (all P < 0.05). The MG area proportion in the upper eyelid was negatively correlated with DVA at 40 dps (R = −0.293, P < 0.001) and at 80 dps (R = −0.304, P < 0.001). Subgroup analysis by MG grade demonstrated that the DVA of patients with severe MG dropout (<25% of the total area) was significantly worse than other mild and moderate groups, both in 40 and 80 dps (all P < 0.05). The patients with CFS showed worse 40 (P < 0.001) and 80 dps (P < 0.001) DVA than the patients without CFS.ConclusionBinocular DVA is significantly associated with DED symptoms and signs. The DED patients with CFS and severe MG dropout and dysfunction have worse DVA.

Abstract
Vision loss is a common, devastating complication of cerebral strokes. In some cases the complete contra-lesional visual field is affected, leading to problems with routine tasks and, notably, the ability to read. Although visual information crucial for reading is imaged on the foveal region, readers often extract useful parafoveal information from the next word or two in the text. In hemianopic field loss, parafoveal processing is compromised, shrinking the visual span and resulting in slower reading speeds. Recent approaches to rehabilitation using perceptual training have been able to demonstrate some recovery of useful visual capacity. As gains in visual sensitivity were most pronounced at the border of the scotoma, it may be possible to use training to restore some of the lost visual span for reading. As restitutive approaches often involve prolonged training sessions, it would be beneficial to know how much recovery is required to restore reading ability. To address this issue, we employed a gaze-contingent paradigm using a low-pass filter to blur one side of the text, functionally simulating a visual field defect. The degree of blurring acts as a proxy for visual function recovery that could arise from restitutive strategies, and allows us to evaluate and quantify the degree of visual recovery required to support normal reading fluency in patients. Because reading ability changes with age, we recruited a group of younger participants, and another with older participants who are closer in age to risk groups for ischaemic strokes. Our results show that changes in patterns of eye movement observed in hemianopic loss can be captured using this simulated reading environment. This opens up the possibility of using participants with normal visual function to help identify the most promising strategies for ameliorating hemianopic loss, before translation to patient groups.

Abstract
Dry eye disease (DED) represents an important public health problem causing visual discomfort which affects the quality of life. This paper investigates the current comprehension of DED on life quality and vision. METHODS This research consists of a cross-sectional study of 121 patients, with a mean age of 70 ± 9 years, diagnosed with DED. All patients were treated in the University Clinic for Ophthalmology in "St. Spiridon" Emergency Hospital, Iasi. For all patients, we evaluated visual acuity on the Snellen chart, tear breakup time (TBUT), Schirmer I test scores, and contrast sensitivity. For this study, we used the Visual Functioning Questionnaire-25 (VFQ-25) version 2000, modified and adapted for this research (19 items). RESULTS Prior to treatment, patients had very high difficulty reading a text in a newspaper or on TV, reading prices on products in shops, or recognizing people they already met. Performing manual work or favorite activities was also very difficult. Post-treatment visual challenges improved in the majority of cases, regardless of the treatment method used. CONCLUSIONS We found that symptomatic dry eye disease was associated with reduced ability in performing several important vision-related daily tasks and has a significant impact on life quality and visual performance.

Abstract
Background Dry eye disease (DED) is a multifactorial disease of the ocular surface, which affects the quality of life and work efficiency of affected patients. The traditional Chinese medicine formula Qiju Dihuang Pill (QJDHP) has a good therapeutic effect on DED. However, the pharmacological mechanism is not clear. Objective To explore the mechanism of QJDHP in the treatment of DED based on network pharmacology. Method The active components in QJDHP were screened in Traditional Chinese Medicine Systems Pharmacology (TCMSP), and putative molecular targets of QJDHP were identified using the SwissTargetPrediction database. DED-related targets were screened by GeneCards and OMIM. We established protein-protein interaction (PPI) and core targets and corresponding active compound network by Cytoscape to identify the core targets and main compounds of QJDHP against DED. DAVID database was utilized for Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Molecular docking was used to evaluate the binding activity between key active compounds and core targets. Results The results of network pharmacology showed that 253 targets of QJDHP were related to DED. PPI network analysis showed the 18 core targets. The binding affinity of docking results ranged from -5.7 to -9.3 kcal/mol, indicating a good docking effect. The results of GO enrichment analysis showed that the mechanism of QJDHP in the treatment of DED mainly involved biological processes such as apoptosis, oxidative stress, response to estrogen, angiogenesis, and the regulation of transcription factors. KEGG analysis showed that QJDHP may be regulated by the TNF signaling pathway, Toll-like receptor signaling pathway, MAPK signaling pathway, and estrogen signaling pathway in the treatment of DED. Conclusion In this study, we demonstrated the multicomponent, multitarget, and multichannel action mechanism of QJDHP in the treatment of DED and provided a foundation for further drug development research.

Abstract
Background and objective Dry eye disease (DED) is one of the most common reasons why patients seek eye care. With increasing age, widespread adoption of technology, and environmental changes, its prevalence has been on the rise, and will likely increase further. Meibomian gland dysfunction (MGD) is the most common cause of DED; however, for a variety of reasons, it is currently underrecognized. We aimed to determine the etiology of DED from a sample of patients visiting our center with dry eye symptoms and study the characteristics of those diagnosed with MGD. Methodology We conducted this prospective observational study from 2016 to 2018. We included patients with two or more dry eye symptoms and excluded those with systemic conditions or structural issues causing dry eye. Each patient underwent a detailed evaluation of the dry eye, including the Ocular Surface Disease Index (OSDI) questionnaire, Oxford corneal staining, Schirmer test 1, tear film break-up time (TBUT), tear meniscus height, and non-contact meibography. All patients subsequently received appropriate treatment. Patients with MGD were evaluated once again after one month. Results We included 250 patients in the study. Their mean (standard deviation) age was 45.3 (16.9) years, and 138 (55%) of them were males. Grittiness and itching were the most common symptoms. MGD was the most common diagnosis, seen in 100 (40%), followed by chronic allergic conjunctivitis. Patients with MGD were more likely to be elderly and had significantly worse DED parameters. Over half of all MGD cases were mild or less severe. With appropriate treatment, all DED metrics improved significantly. Conclusions MGD was the most common cause of DED in our sample. Patients with MGD were more likely to be elderly and had more severe DED, consistent with other studies in the literature. With specific treatment of MGD, there was a significant improvement in the patients' condition. DED is a growing ocular health issue that causes great detriment to patients’ quality of life and finances. Our findings support the need for a detailed evaluation and specific treatment of patients presenting with dry eye symptoms.

Abstract
Outcome measures used to assess efficacy of dry eye therapeutics have not been consistently applied in clinical settings, nor have they been shown to correlate with functional outcomes. We propose that corneal staining, a clinically meaningful dry eye parameter, should be used as a standard objective outcome measure across all clinical trials evaluating dry eye treatments. We justify this based on evidence regarding its relationship to vision and vision related quality-of-life. In addition, corneal staining has been shown to correlate with ocular surface inflammation, a well elucidated aspect of dry eye pathophysiology and an active area in therapeutics research. No one outcome measure explored herein correlates perfectly to this heterogenous disease. However, there is mounting evidence showing the correlation between corneal staining and functional visual indices. We hope that future clinical trials will standardize corneal staining as a measure to determine the efficacy of interventions and justify their clinical utility.

Abstract
PURPOSE To assess the efficacy, safety, and tolerability of a topical water-free cyclosporine A formulation (CyclASol 0.1% ophthalmic solution) in comparison with vehicle for the treatment of dry eye disease (DED). METHODS Three hundred twenty-eight patients were enrolled in this prospective, 12-week, multicenter, randomized, double-masked, confirmatory, vehicle-controlled clinical study. After a 2-week run-in period, eligible DED patients were randomized 1:1 to either CyclASol 0.1% or vehicle twice daily. The primary efficacy endpoint was change from baseline in total corneal fluorescein staining (National Eye Institute scale), and the second hierarchical primary efficacy endpoint was change from baseline in the Ocular Surface Disease Index score, both at 4 weeks. Secondary efficacy and safety assessments included conjunctival lissamine green staining (Oxford scale), visual analog scales for dry eye symptoms, and adverse event. RESULTS Treatment with CyclASol 0.1% was superior to vehicle in the primary endpoint: total corneal fluorescein staining at week 4 (Δ -0.8; 95% confidence interval, -1.3 to -0.4; P = 0.0002, analysis of covariance). This difference had already reached statistical significance after 2 weeks and was maintained throughout the study. The study did not statistically meet its second hierarchically tested primary endpoint: Ocular Surface Disease Index score (P = 0.2634). However, CyclASol 0.1% treatment showed statistically significant improvement compared with that of vehicle in the eye dryness score at week 4 (Δ -4.783; 95% confidence interval, -9.129 to -0.438; P = 0.0311). CONCLUSIONS CyclASol 0.1% was effective in treating signs and symptoms of DED. It significantly reduced corneal and conjunctival staining and improved ocular dryness compared with vehicle. CyclASol 0.1% was safe and showed excellent tolerability.

Abstract
CLINICAL RELEVANCE Dry eye disease could result in vision-related subjective symptoms even in patients with good best-corrected visual acuity. The standard deviation of corneal power and the surface asymmetry index could be indicators of treatment efficacy in dry eye. BACKGROUND Few studies have examined changes in optical quality before and after dry eye treatment. Here, we evaluated changes in optical quality in patients with dry eye before and after treatment and identified potential indicators of dry eye-treatment efficacy. METHODS Twenty-five right eyes of 25 untreated patients with dry eye were included. The same ocular-surface and optical-quality examinations were performed before and after two-weeks of treatment with hyaluronate in conjunction with fluorometholone eye drops. The Ocular Surface Disease Index, tear film break-up time, and corneal fluorescein staining were measured. Contrast sensitivity was used to measure resolution capability, the double-pass Optical Quality Analysis System to examine the modulation transfer function, Strehl ratio, and objective scattering index, and OPD Scan III to measure anterior corneal aberrations over 4-mm analytical zones including total corneal and high-order aberrations. The standard deviation of corneal power, surface regularity index, and surface asymmetry index were also measured. Paired sample t-tests and Spearman's correlations were used for the analyses. RESULTS The Ocular Surface Disease Index, tear film break-up time, and corneal fluorescein staining improved after two weeks of treatment. Contrast sensitivity in photopic, photopic with glare, scotopic, and scotopic with glare conditions all improved (p < 0.05), as did the modulation transfer function, Strehl ratio, and objective scattering index (p = 0.001, p = 0.008, and p = 0.001, respectively). Total corneal aberrations and the surface regularity index did not significantly differ before and after treatment; corneal high-order aberrations, standard deviation of corneal power, and the surface asymmetry index significantly improved after treatment (p = 0.045, p = 0.019, and p = 0.049, respectively). Changes in standard deviation of corneal power and in surface asymmetry index correlated with change in corneal fluorescein staining (p = 0.006 and p = 0.007, respectively). CONCLUSION Optical quality in patients with dry eye improved after treatment. The standard deviation of corneal power and surface asymmetry index could be indicators of treatment efficacy in dry eye.

Abstract
Dry eye disease is characterized by tear film instability that can result in ocular surface damage. Patients with dry eye disease may experience ocular pain/discomfort and visual disturbances that may negatively impact quality of life. Increased use of digital screens for work, communication, and entertainment, especially during times of pandemic, may contribute to dry eye. Extensive cross-sectional studies have shown that digital screen use duration is associated with an increased risk of severe symptoms and clinical diagnosis of dry eye disease in adults. Smartphone use duration has also been found to be greater in school-age children with dry eye disease than in those without dry eye disease. A commonly accepted hypothesis for the relationship between digital screen use and dry eye disease is that digital screen use changes blinking dynamics, leading to ocular dryness. This review describes evidence that digital screen use is associated with dry eye disease, that digital device use alters blinking dynamics, and that dry eye affects mental health and work productivity in digital screen users. Helpful prevention and management strategies for dry eye disease exist for those who use digital screens.

Purpose TO assess perceptions and implications of COVID-19 infection across the spectrum of individuals with visually impairment (VI) and those with normal sight. Design Prospective cross-sectional comparative study. Methods Setting: institutional. Patients: 232 patients and their caregivers. Four groups were created based on better eye characteristics: blind (best-corrected distance visual acuity [BCDVA] <3/60 or visual field <10 central degrees); severe VI (BCDVA ≤3/60 to <6/60; vertical cup-to-disc ratio ≥0.85 or neuroretinal rim width ≤0.1); moderate VI (BCDVA ≤6/60 to <6/18); or no or mild VI (controls: BCDVA ≥6/18) based on International Classification of Diseases-10 criteria and Foster and Quigley's consensus definition of glaucoma. Procedure: telephone questionnaires. Main outcome measures: differences in perceptions and implications of COVID-19 infection across various levels of VI. Caregiver perceptions were a secondary outcome measure. Results Surveys were completed by 232 participants, with 58 participants in each VI group. Mean age was 58.9 ± 13.2 years old. Greater degrees of VI were associated with older age (P = .008) and lower education level (P = .046). Blind participants more commonly perceived vision as a risk factor for contracting COVID-19 (P = .045), were concerned about access to health care (P <.001), obtained news through word of mouth (P <.001), and less commonly wore masks (P = .003). Controls more commonly performed frequent handwashing (P = .001), were aware of telemedicine (P = .029), and had fewer concerns about social interactions (P = .020) than groups with substantial VI. All caregivers reported more frequent patient care since the COVID-19 pandemic began. Conclusions The pandemic might have had a disproportionate impact on the visually impaired, and evidence-based assessments of COVID-19 health outcomes in this population are warranted.

Abstract
Purpose Among adult individuals with dry eye, assess the self-reported impact of the COVID-19 pandemic on (1) dry eye-related visual function, (2) reading efficiency, and (3) dry eye treatments used. Methods In June–July 2020, we conducted an online survey of adults with dry eye who spent at least somewhat more time at home during the pandemic than before. Consistent with TFOS DEWS II guidelines, we categorized respondents into mild, moderate, or severe dry eye based on treatment usage. Results We included 388 respondents: 97 respondents (25%) with mild, 80 (21%) with moderate, and 211 (54%) with severe dry eye. In all three groups, screen/reading time generally doubled during the pandemic. Reduced work-related efficiency was noted by a considerable proportion of respondents (moderate dry eye: 51%, mild: 39%, and severe: 38%). Compared with respondents with mild dry eye, respondents with moderate dry eye were considerably more likely to note worsening symptoms: eye pain (OR = 2.57, 95% CI 1.22–5.41), headache from eye symptoms (OR = 2.34, 95% CI 1.11–4.90), and difficulty concentrating because of eye symptoms (OR = 2.79, 95% CI 1.37–5.66). Respondents with moderate dry eye with Sjögren's syndrome were most likely to note these. Respondents with severe dry eye were more likely than respondents with mild dry eye to report losing access to dry eye-related treatments (OR = 2.62, 95% CI 1.36–5.03). Conclusions The COVID-19 pandemic-related eye strain may be impacting symptoms, performance, and ultimately employment, especially for those with moderate dry eye. This may be compounding the already-high dry eye-related societal burden.

Abstract
ZusammenfassungDas Trockene Auge führt häufig zu Sehstörungen trotz guter Sehleistung in der Standardvisusprüfung. Die Beschwerden treten meist beim Lesen, Arbeiten am Computer und/oder beim Autofahren auf. Grund ist die schlechte optische Qualität der Augenoberfläche beim Trockenen Auge mit Zunahme von topometrischer Irregularität und Asymmetrie, Anstieg des irregulären Astigmatismus, Zunahme der kornealen und okulären Aberrationen höherer Ordnung, Abnahme der Kontrastsensitivität und Zunahme der Lichtstreuung. Die funktionelle Sehschärfe repräsentiert die Visusfunktion im Zeitverlauf und reflektiert die Visusleistung eines Individuums bei täglichen Aktivitäten. Sie ist beim Trockenen Auge signifikant reduziert im Vergleich zu Normalprobanden. Eine Vielzahl von Testmethoden zur Evaluierung der funktionellen Sehschärfe wurde beschrieben. Kein Verfahren hat sich bisher in der täglichen Praxis durchgesetzt.

Abstract
PURPOSE To evaluate demographic and lifestyle factors associated with aqueous deficient and evaporative dry eye disease. METHODS A total of 1125 general public visitors (707 females, mean ± SD age, 33 ± 21, range 5-90 years) at the Royal Society Summer Science Exhibition were recruited in a cross-sectional study. A demographic and lifestyle factor questionnaire was administered, and dry eye symptomology (DEQ-5 score), ocular surface characteristics (conjunctival hyperaemia, and infrared meibography), and tear film parameters (tear meniscus height, non-invasive breakup time, and lipid layer grade) were evaluated for the left eye of each participant within a single session. The diagnostic criteria for dry eye disease subtypes were adapted from the rapid non-invasive dry eye assessment algorithm. RESULTS Overall, 428 (38%) participants fulfilled the diagnostic criteria for dry eye disease, 161 (14%) with aqueous deficient dry eye disease, and 339 (30%) with evaporative dry eye disease. Multivariate logistic regression demonstrated that advancing age, female sex, reduced sleep duration, higher psychological stress, and poorer self-perceived health status were independently associated with aqueous deficient dry eye disease (all p < 0.05). Significant risk factors for evaporative dry eye disease included advancing age, East and South Asian ethnicity, contact lens wear, increased digital device screen exposure, higher psychological stress, and poorer self-perceived health status (all p < 0.05). CONCLUSIONS Both subtypes of dry eye disease were associated with several unique and shared demographic and lifestyle factors. The findings of this study could inform future research design investigating the utility of targeted screening and risk factor modification for the prevention and management of dry eye disease.

Abstract
Clinical relevance: Dry eye disease is a common chronic ocular condition, which is acknowledged to have adverse impacts on quality of life and work productivity.Background: The wide-reaching impacts of dry eye disease on mental health and quality of life have received growing attention in recent years. The purpose of this study was therefore to investigate the relationship between dry eye disease, self-perceived health status, and self-reported psychological stress burden.Methods: Three hundred and twelve community residents (178 females, 134 males; mean ± SD age, 38 ± 21 years) with no major systemic, ophthalmic, or psychiatric conditions (other than dry eye disease), were recruited in a cross-sectional study. Self-perceived health status and self-reported psychological stress burden were assessed, and dry eye symptomology, ocular surface characteristics, and tear film quality were evaluated for each participant within a single clinical session, in accordance with the global consensus recommendations of the Tear Film and Ocular Surface Society Dry Eye Workshop II reports.Results: Multivariate regression analysis, adjusted for age, sex, ethnicity, and contact lens wear, demonstrated that improved self-perceived health status was associated with decreased odds of dry eye disease, aqueous tear deficiency and meibomian gland dysfunction (all p < 0.05). Increased self-reported psychological stress burden was positively associated with dry eye disease, aqueous tear deficiency and meibomian gland dysfunction (all p ≤ 0.01).Conclusion: Dry eye disease is associated with poorer self-perceived health status and greater self-reported psychological stress burden. The findings of this study highlight the wide-reaching impacts of dry eye disease, and the importance of minimising the impacts of the condition with optimised management and actioning inter-disciplinary referral for affected patients where necessary.

Clin Ther 2021; 43:613-628. [PMID: 33546885 DOI: 10.1016/j.clinthera.2020.12.023] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Revised: 12/27/2020] [Accepted: 12/31/2020] [Indexed: 11/26/2022]
Abstract
PURPOSE The purpose of this study was to explore the efficacy, safety, and tolerability of a novel cyclosporine formulation for dry eye disease (DED). METHODS This is an exploratory, multicenter, single-blind, randomized, positive-controlled Phase II clinical trial between cyclosporine ophthalmic gel (CyclAGel) and an open-label comparator (Restasis, positive control). A total of 240 eligible patients with moderate to severe DED were randomized to 4 study groups: CyclAGel 0.05%/once daily (QD) (n = 59), CyclAGel 0.05%/BID (n = 60), CyclAGel 0.1%/QD (n = 60), and Restasis 0.05%/BID (n = 61). After receiving BID dosing of hypromellose eye drops during a 2-week run-in period, patients were randomized to the respective treatment group and dosed QD or BID for 12 weeks. Efficacy was assessed based on a number of sign and symptom end points, including eye dryness score (visual analog scale), 6 other parameters of symptoms for dryness (burning/stinging, itching, foreign body sensation, discomfort, sensitivity to light, and pain), and corneal fluorescein staining. The Schirmer test was used to assess dry eye symptoms (visual analog scale severity) at visit 3 (week 2), visit 4 (week 6), and visit 5 (week 12). FINDINGS CyclAGel showed a consistent improvement in eye dryness score and the 6 other parameters of symptoms for dryness, corneal fluorescein staining, breakup time, and Schirmer test scores compared with Restasis over the 12-week treatment period. However, there were no statistically significant differences between CyclAGel and Restasis after baseline corrections were made, and the results of the full analysis set remained consistent with those of the per-protocol set (P > 0.05). Moreover, each CyclAGel-treated group (0.05%/QD, 0.05%/BID, and 0.1%/QD) exerted better effects than the Restasis group, and CyclAGel 0.05%/QD showed the most significant improvement. The number of ocular-related treatment-emergent adverse events was low in all treatment groups, with no serious drug-related treatment-emergent adverse events. IMPLICATIONS CyclAGel showed excellent safety, tolerability, and comfort profiles at 2 concentrations and frequency in moderate to severe DED.

Abstract
Dry eye disease (DED) is one of the most common ocular surface disorders characterised by a deficiency in quality and/or quantity of the tear fluid. Due to its multifactorial nature involving several inter-related underlying pathologies, it can rapidly accelerate to become a chronic refractory condition. Therefore, several therapeutic interventions are often simultaneously recommended to manage DED efficiently. Typically, artificial tear supplements are the first line of treatment, followed by topical application of medicated eyedrops. However, the bioavailability of topical eyedrops is generally low as the well-developed protective mechanisms of the eye ensure their rapid clearance from the precorneal space, thus limiting ocular penetration of the incorporated drug. Moreover, excipients commonly used in eyedrops can potentially exhibit ocular toxicity and further exacerbate the signs and symptoms of DED. Therefore, formulation development of topical eyedrops is rather challenging. This review highlights the challenges typically faced in eyedrop development, in particular, those intended for the management of DED. Firstly, various artificial tear supplements currently on the market, their mechanisms of action, as well as their application, are discussed. Furthermore, formulation strategies generally used to enhance ocular drug delivery, their advantages and limitations, as well as their application in commercially available DED eyedrops are described.

Abstract
PURPOSE To examine the association between modifiable lifestyle factors and dry eye disease. METHODS Three hundred and twenty-two community residents (186 females, 136 males; mean ± SD age, 41 ± 22 years) with no major systemic or ophthalmic conditions (other than dry eye disease) were recruited in a cross-sectional study. A lifestyle factor questionnaire was administered, and dry eye symptomology, ocular surface characteristics, and tear film quality were evaluated for each participant within a single clinical session, in accordance with the global consensus recommendations of the TFOS DEWS II reports. RESULTS A total of 111 (34 %) participants fulfilled the TFOS DEWS II diagnostic criteria for dry eye disease. Multivariate regression analysis demonstrated that advancing age, female sex, East Asian ethnicity, and increased digital screen exposure time were positive risk factors for dry eye disease (all p < 0.05), while increased caffeine consumption was a protective factor (p = 0.04). CONCLUSIONS Increased digital screen exposure time and reduced caffeine consumption were modifiable lifestyle factors associated with higher odds of dry eye disease. These findings might contribute to informing the design of future prospective research investigating the efficacy of preventative intervention and risk factor modification strategies.

Abstract
Purpose: To evaluate the relation of the tear film on the quality of vision comparing parameters in normal patients to those having dry eye disease. Methods: 50 normal and 50 eyes with dry eye disease (DED) were included in the study. Patients were screened for dry eye with Schirmer's test, tear break up time, ocular surface staining, and assessment of meibomian gland disease. Their quality of vision was assessed using the Optical quality analysis system (OQAS). The results of dry eye evaluation were correlated with the parameters on the OQAS especially the mean objective scatter index (OSI). Results: Patients with dry eye and unstable tear film were found to have a significantly worse quality of vision and optical scatter (P < 0.05). They were also noted to have fluctuation of vision between blinks. Conclusion: Tear film optics can have an important bearing on the quality of vision and quality of life. A detailed assessment preoperatively will help improve surgical outcomes and patient satisfaction.

Abstract
PURPOSE To evaluate the comparability, discriminative ability, and optimal thresholds for non-invasive tear film breakup time measurements obtained from the Oculus Keratograph 5M and Medmont E300 in detecting other signs and symptoms of dry eye disease, as defined by the TFOS DEWS II diagnostic criteria. METHODS One hundred and thirty-four participants (53 male, 81 female), with a mean ± SD age of 48 ± 20 years, were recruited into a prospective, investigator-masked, diagnostic accuracy study. Dry eye symptomology, tear film parameters (including non-invasive Keratograph and Medmont breakup time), and ocular surface staining were evaluated in a single clinical session. RESULTS Significant positive correlation was observed between the two automated instruments (p < 0.001), although non-invasive breakup time measurements obtained from the Medmont were significantly longer (p < 0.001), and demonstrated greater intra-subject and inter-subject variability (all p < 0.001). The areas under the ROC curves exceeded 0.65 for both instruments, and the discriminative abilities were comparable (p = 0.53). The Youden optimal diagnostic threshold for non-invasive tear film stability measurements obtained from the Keratograph was ≤8 seconds, and the optimal cut-off for breakup time measurements obtained from the Medmont was ≤14 seconds. CONCLUSIONS Despite significant positive correlation, breakup time measurements obtained from the Keratograph and Medmont were not directly interchangeable. Measurements from the Medmont were significantly longer and demonstrated greater intra-subject and inter-subject variability, although the two automated, non-invasive methods for assessing tear film stability exhibited comparable overall performance in diagnosing dry eye disease.

Abstract
PURPOSE To investigate the impact of ageing on ocular surface parameters, and empirically determine optimal prognostic cut-off ages for clinical markers of dry eye disease, aqueous tear deficiency, and meibomian gland dysfunction. METHODS A total of 1331 community residents (785 females, 546 males; mean ± SD age, 38 ± 19 years) were recruited in a prospective registry-based cross-sectional study. Dry eye symptomology, ocular surface characteristics, and tear film quality were evaluated for each participant within a single clinical session, in accordance with the global consensus recommendations of the TFOS DEWS II reports. RESULTS Multivariate regression analysis demonstrated positive associations between ageing and clinical markers of dry eye disease (all p ≤ 0.001). The Youden-optimal prognostic cut-off ages for signs of meibomian gland dysfunction occurred during the third decade of life (24-29 years); the optimal predictive ages for lid wiper epitheliopathy, tear film instability, hyperosmolarity, and dry eye symptoms occurred during the fourth decade of life (31-38 years); while the optimal prognostic thresholds for signs of aqueous tear deficiency and ocular surface staining occurred in the fifth and sixth decades of life (46-52 years). CONCLUSIONS Advancing age is a significant risk factor for dry eye disease, which represents a growing public health concern with the ageing population worldwide. Signs of meibomian gland dysfunction appeared earlier in the natural history of disease progression, and the brief delay prior to the development of other clinical dry eye signs might represent a window of opportunity for preventative interventions in the young adult age group.

Abstract
BACKGROUND The global prevalence of dry eye disease (DED) ranged from 5% to 50%, accompanied by the yearly increasing trend and younger onset. To date artificial tear serves as a mainstay therapy for DED management. It is noteworthy that, acupuncture has been accepted for treating DED with a time-honored history in China. However, no systematic review has been updated till now, which is focusing on comparing acupuncture vs. artificial tears for DED management. METHODS Eight databases will be searched with the language restrictions of English and Chinese from their inception to July 1, 2020. Randomized controlled trials comparing acupuncture versus artificial tears for DED treatment were enrolled. Identification, research inclusion, data extraction and assessment of the risk of bias were conducted independently by 2 or more reviewers. The primary outcomes were Schirmer I test and tear break-up time. We used Review Manager Software (v.5.3) for assessing the risk of bias and all statistical analyses. RESULTS Based on the evidence obtained, whether the effect of acupuncture was equal to or even better than that of artificial tear therapy in the treatment of DED would be elaborated. CONCLUSION In summary, this review would provide a relatively convincing conclusion on whether acupuncture deserves to be recommended as an adjunct treatment for DED, so as to propose some significant insights for the doctors handling with DED.

Abstract
BACKGROUND Although most patients with visual impairment due to corneal diseases can be treated successfully with surgery, some require visual rehabilitation to restore reading ability. To evaluate the best LVAs especially in terms of reading speed and characterize this specific patient group we performed a prospective, randomized cross-over trial. METHODS All 34 patients underwent a detailed examination (slit-lamp, funduscopy, SD-OCT, ETDRS) as screening. Only patients with corneal diseases without other ocular diseases were included. Reading-speed was assessed with International-Reading-Speed-Texts (IReST) consecutively with five different LVAs (low vision aids) during one day in a randomized cross-over design. Corneal haze was quantified with corneal densitometry (Pentacam). RESULTS Patients were either visually impaired (n = 28), severely impaired (n = 4) or legally blind (n = 2). Patients read significantly faster with LVAs (p < 0.0001). Fastest reading speed could be achieved with video magnifier (CCTV). Optical magnifier and portable-electronic magnifier enabled significantly lower reading speeds (p < 0.01). In a subgroup of patients (VA < 3/60,n = 6) black background enabled patients to read significantly faster compared to white background (p = 0.03). CONCLUSION Patients with low magnification requirement can be treated successfully with optical LVAs and portable-electronic magnifiers. More severely afflicted patients need a CCTV. Black background enables fastest reading-speeds, probably due to less blinding. Visual impairment can be estimated with corneal densitometry. Our trial confirms the capability of LVAs to successfully restore the reading ability in patients with corneal diseases, which is a crucial part of visual rehabilitation. TRIAL REGISTRATION This trial was registered at the German Clinical Trials Register as DRKS00010887 at 09.08.2016.

Abstract
PURPOSE To assess the effects of sustained gazing on visual function of dry eye patients. DESIGN Prospective, comparative before-and-after study. METHODS A total of 176 patients with dry eye and 33 control subjects ≥50 years old were included. Dry eye symptomatology along and clinical parameters were assessed. Out-loud reading speed was measured using the International Reading Speed Test (IReST) as words per minute (wpm). Reading speed was repeated using different IReST excerpts following 30-minute silent reading. RESULTS At baseline, there were no differences between dry eye patients and control subjects with respect to reading speed (172 vs 180 wpm, respectively; P = 0.21) or the time to read the excerpt (33 vs 30 seconds, respectively; P = 0.17). After silent reading, the dry eye patients had decreased reading speed and increases in the length of time to read the passage compared to baseline (161 vs 172 wpm, respectively; P = 0.002; and 38 vs 33 seconds, respectively; P < 0.001). The control subjects did not show significant differences for either parameter. There were significant differences with respect to both parameters between the dry eye and control groups after sustained gazing (161 vs 188 wpm, respectively; P = 0.006; and 38 vs 31 seconds, respectively; P = 0.003). Each 1-point increase in baseline corneal staining score (0-6) led to a 5-wpm reduction in reading speed (95% confidence interval, -8 to -1; P = 0.01). CONCLUSIONS Sustained gazing, such as in silent reading, has a measurable negative impact on visual performance of dry eye patients. Corneal staining represents a clinical parameter relevant to visual function.

Abstract
Importance Dry eye is a common ocular surface condition with significant influence on patient quality of life and societal economic burden. There is an urgent need to prioritize new research for dry eye. Objective To identify and rank research questions and outcomes important to patients with dry eye. Design, Setting, and Participants This study was conducted using the following 6 steps: (1) identifying research questions from a previous survey of clinicians who treat patients with dry eye; (2) identifying outcomes from existing research (systematic reviews and their cited clinical trials in the Cochrane Eyes and Vision US Satellite database of eyes and vision reviews, and National Eye Institute-funded clinical trials registered on ClinicalTrials.gov) as of June 13, 2017; (3) identifying a sample of patients with dry eye from the email subscribers to the online newsletter KeratoScoop; (4) and (5) conducting a 2-round Delphi survey of those patients online in November and December 2017, respectively; and (6) designating and ranking questions and outcomes as important. Main Outcomes and Measures Importance assigned to research questions and outcomes for dry eye. A research question or outcome ranked by at least 75% of patients as 6 or higher on a scale of 0 to 10 was considered important. Results Among the 420 patients from 15 countries who completed both rounds of the Delphi survey, most were 60 years of age or older (233 [56%]), female (348 [83%]), white (393 [94%]), and of non-Hispanic ethnicity (398 [95%]). Among the 12 questions that clinicians had previously prioritized, patients rated 8 as important. The top 3 questions pertained to effectiveness of patient education, environmental modifications, and topical anti-inflammatory eye drops for dry eye. Among the 109 outcomes identified in existing research on dry eye, patients rated 26 as important. Ten of these 26 were unpopular in existing research, with fewer than 10% of 158 studies reporting these outcomes. Of the 10 most important outcomes, 9 were associated with symptoms or quality of life. The 3 outcomes rated most important by patients were ocular burning or stinging, ocular discomfort, and ocular pain. Conclusions and Relevance This study identified research questions and outcomes important to patients with dry eye. A considerable gap was noted between outcomes in existing research on dry eye and outcomes patients consider important. Future research on dry eye should consider addressing the important research questions and outcomes identified herein, taking into account the patient perspective.

Abstract
SIGNIFICANCE Patients with dry eye frequently report difficulty with reading. However, the impact of dry eye on reading has not been studied in detail. This study shows the unfavorable effect of dry eye on reading speed and offers mechanisms that may be responsible. PURPOSE The purpose of this study was to evaluate the impact of dry eye signs as well as symptoms on both short-duration out-loud and prolonged silent reading. METHODS This study included 116 patients with clinically significant dry eye, 39 patients with dry eye symptoms only, and 31 controls, 50 years or older. After the Ocular Surface Disease Index (OSDI) questionnaire, objective testing of dry eye (tear film stability studies, Schirmer's test, and ocular surface staining) was performed. Total OSDI score and two subscores (vision related and discomfort related) were calculated. A short-duration out-loud reading test and a 30-minute sustained silent reading test were performed. Reading speed for each test was calculated as words per minute (wpm) and compared across the three groups. RESULTS Patients with clinically significant dry eye read slower than controls measured with sustained silent reading test (240 vs. 272 wpm, P = .04), but not with short-duration out-loud reading test (146 vs. 153 wpm, P = .47). Patients with dry eye symptoms only did not have slower reading speed measured using either reading test as compared with controls. However, vision-related OSDI subscore independently was associated with slower reading speed (P = .02). Multivariable regression models demonstrated that each 1-point (between 0 and 6) increase in corneal staining score led to a 10-wpm decrease in sustained silent reading speed (P = .01). CONCLUSIONS This study demonstrates a significant negative impact of dry eye (particularly presence of corneal staining) on prolonged reading. Prolonged reading task may serve as an objective clinically relevant test to measure the impact of dry eye on vision-related quality of life.

Abstract
BACKGROUND Topical cyclosporine A (also known as ciclosporin A) (CsA) is an anti-inflammatory that has been widely used to treat inflammatory ocular surface diseases. Two CsA eyedrops have been approved by US Food and Drug Administration for managing dry eye: Restasis (CsA 0.05%, Allergan Inc, Irvine, CA, USA), approved in 2002, and Cequa (CsA 0.09%, Sun Pharma, Cranbury, NJ, USA), approved in 2018. Numerous clinical trials have been performed to assess the effectiveness and safety of CsA for dry eye; however, there is no universal consensus with regard to its effect. OBJECTIVES To assess the effectiveness and safety of topical CsA in the treatment of dry eye. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2018, Issue 2); Ovid MEDLINE; Embase.com; PubMed; Latin American and Caribbean Health Sciences Literature Database (LILACS); ClinicalTrials.gov; and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). We did not use any date or language restrictions in the electronic search for trials. We last searched the electronic databases on 16 February 2018. SELECTION CRITERIA We included randomized controlled trials (RCTs) of people with dry eye regardless of age, sex, severity, etiology, or classification of dry eye. We included RCTs in which different concentrations of topical CsA were compared with one another or with artificial tears, placebo, or vehicle. We also included RCTs in which CsA in combination with artificial tears was compared to artificial tears alone. DATA COLLECTION AND ANALYSIS We followed the standard Cochrane methodology and assessed the certainty of the evidence using GRADE. MAIN RESULTS We included 30 RCTs (4009 participants) with follow-up periods ranging from 6 weeks to 12 months. We studied dry eye of various severity and underlying causes. The interventions investigated also varied across RCTs: CsA versus artificial tears; CsA with artificial tears versus artificial tears alone; and in some studies, more than one concentration of CsA. Artificial tears were used as adjunctive to study medication in all but five trials. Almost all trials had deficiencies in the reporting of results (e.g. reporting P values or direction only), precluding the calculation of between-group estimates of effect or meta-analysis.Eighteen trials compared topical CsA 0.05% plus artificial tears versus vehicle plus artificial tears or artificial tears alone. One trial reported subjective symptoms of dry eye at 6 months and the results were in favor of CsA (mean difference (MD) -4.80, 95% confidence interval (CI) -6.41 to -3.19; low-certainty evidence). Two trials reported MD in ocular surface dye staining at 6 months, but the results were inconsistent in these two trials (MD -0.35, 95% CI -0.69 to -0.01 in one and MD 0.58, 95% CI 0.06 to 1.10 in the other; low-certainty evidence). Four trials reported MD in Schirmer test scores at 6 months and the estimates ranged from -4.05 (95% CI -6.67 to -1.73) to 3.26 (95% CI -1.52 to 5.00) (low-certainty evidence). Three trials reported risk ratio (RR) of improved Schirmer test scores at 6 months; estimates ranged from 0.98 (95% CI 0.83 to 1.17) to 3.50 (95% CI 2.09 to 5.85) (low-certainty evidence). Four trials reported MD in tear film stability measured by tear break-up time at 6 months and the estimates ranged from -1.98 (95% CI -3.59 to -0.37) to 1.90 (95% CI 1.44 to 2.36) (low-certainty evidence). Three trials reported RR of improved tear break-up time at 6 months and the estimates ranged from 0.90 (95% CI 0.77 to 1.04) to 4.00 (95% CI 2.25 to 7.12) (low-certainty evidence). Three trials reported frequency of artificial tear usage at 6 months without providing any estimates of effect; the direction of effect seem to be in favor of CsA (low-certainty evidence). Because of incomplete reporting of the results data or considerable statistical heterogeneity, we were only able to perform a meta-analysis on mean conjunctival goblet cell density. Mean conjunctival goblet cell density in the CsA treated group may be greater than that in the control group at the end of follow-up at four and 12 months (MD 22.5 cells per unit, 95% CI 16.3 to 28.8; low-certainty evidence). All but two trials reported adverse events that included burning and stinging. Participants treated with CsA may be more likely to have treatment-related adverse events than those who treated with vehicle (RR 1.33, 95% CI 1.00 to 1.78; low-certainty evidence).Other comparisons evaluated were CsA 0.05% plus artificial tears versus higher concentrations of CsA plus artificial tears (4 trials); CsA 0.05% versus placebo or vehicle (4 trials); CsA 0.1% plus artificial tears versus placebo or vehicle plus artificial tears (2 trials);CsA 0.1% cationic emulsion plus artificial tears versus vehicle plus artificial tears (2 trials); CsA 1% plus artificial tears versus placebo plus artificial tears (3 trials); and CsA 2% plus artificial tears versus placebo plus artificial tears (3 trials). Almost all of these trials reported P value or direction of effect only (mostly in favor of CsA), precluding calculation of between-group effect estimates or meta-analyses. AUTHORS' CONCLUSIONS Despite the widespread use of topical CsA to treat dry eye, we found that evidence on the effect of CsA on ocular discomfort and ocular surface and tear film parameters such as corneal fluorescein staining, Schirmer's test, and TBUT is inconsistent and sometimes may not be different from vehicle or artificial tears for the time periods reported in the trials. There may be an increase in non-serious, treatment-related adverse effects (particularly burning) in the CsA group. Topical CsA may increase the number of conjunctival goblet cells. However, current evidence does not support that improvements in conjunctival mucus production (through increased conjunctival goblet cells) translate to improved symptoms or ocular surface and tear film parameters. All published trials were short term and did not assess whether CsA has longer-term disease-modifying effects. Well-planned, long-term, large clinical trials are needed to better assess CsA on long-term dry eye-modifying effects. A core outcome set, which ideally includes both biomarkers and patient-reported outcomes in the field of dry eye, is needed.

Abstract
INTRODUCTION Dry Eye (DE) is a multifactorial condition with a variable clinical presentation. This highly prevalent disease has multiple symptoms and signs that often do not correlate with one another. As such, the diagnosis of DE can be challenging to make, and a systematic approach must be taken. AREAS COVERED We review the different methods commonly utilized to evaluate a patient complaining of DE symptoms. Included in this review are clinical examination techniques, point of care tests, and imaging techniques. EXPERT OPINION DE is an umbrella term that encompasses different etiologies and pathophysiological mechanisms. The current definition recognizes tear instability, high osmolarity, inflammation, and neuro-sensory dysfunction as causative entities. The approach to DE begins with a systematic assessment of symptoms and signs, evaluating for both nociceptive and neuropathic sources of symptoms. Future research is needed to develop tests that assess neurosensory status in DE and couple point of care tests with therapeutic algorithms.

Purpose We evaluated the relationship between ocular surface clinical tests and quality of vision in patients with dry eye disease (DED). Methods In this study, 136 eyes of 72 dry eye patients were evaluated retrospectively using the ocular surface disease index (OSDI), measurement of tear film break-up time (TBUT), the Oxford score, Van Bijsterveld score, and Schirmer I test. Quality of vision was assessed with the optical quality analysis system (OQAS) using the objective scatter index (OSI) recorded over 20 seconds without blinking. Correlations between dry eye symptoms and signs, and OSI measurements were evaluated. Results The OSI and OSI standard deviation (OSI SD) were correlated with TBUT (r = -0.21, P = 0.013 and r = -0.18, P = 0.038, respectively), Oxford score (r = 0.31, P = 0.0002 and r = 0.18, P = 0.032, respectively), and the Van Bijsterveld score (r = 0.33, P = 0.0001 and r = 0.25, P = 0.003, respectively). The OSI also was correlated with the Schirmer test (r = -0.19, P = 0.025), OSDI (r = 0.17, P = 0.04), and the ocular symptoms subscale of the OSDI (r = 0.21, P = 0.01). OSI SD was correlated with the environmental triggers subscale of the OSDI (r = 0.21, P = 0.016). Conclusions Quality of vision measured with the OQAS was correlated with dry eye symptoms and signs. The OQAS could be a useful tool to better evaluate visual function in patients with DED. Translational Relevance The OQAS provides a better understanding of patient complaints about alteration of vision quality. It might be useful to integrate this objective system in severity assessments and follow-up of DED, especially for treatment evaluations.

Abstract
BACKGROUND The aim of this research is to initiate a 5-year natural history study of dry eye disease (DED) using objectively assessed and patient-reported outcomes, to explore the hypothesis that DED is a progressive condition that has substantive and measurable impacts not only on the ocular surface, but on quality of life and visual functioning. Our objective for this report is to examine the baseline data. METHODS A multicenter, prospective, controlled, observational study of Level 2 (mild-to-moderate) DED patients based on International Task Force Delphi Panel severity grading, and controls, documented baseline measures (including tear film biomarkers and quality of life). Tear cytokine concentrations were also measured in the tear film. Patients were using artificial tears as needed. RESULTS Two hundred seventeen DED patients and 67 gender- and age-matched controls were enrolled. A majority were females and Caucasian and groups did not differ significantly in terms of gender, race, or age. Differences between DED and matched controls, at baseline, included mean scores for Ocular Surface Disease Index (31.7 vs 4.1, P < 0.0001), Schirmer test (5.7 vs 15.3 mm, P < 0.0001), corneal staining (1.4 vs 0.2, P < 0.0001), conjunctival staining (1.4 vs 0.3, P < 0.0001), and tear break-up time (5.7 vs 8.5 s, P < 0.0001). Tear cytokines levels were determined and included interferon-γ, interleukin (IL)-1β, IL-2, IL-4, IL-6, IL-8, tumor necrosis factor-α, epidermal growth factor, IL-13, IL-17, IL-1α, and inducible protein-10. The mean levels of IL-8 and IL-6 were slightly higher in the DED group at baseline. Blurred vision was reported as moderate/severe/very severe at baseline in 57.6% of DED patients vs.10.5% of normal controls (P < 0.0001). DED patients reported greater reductions in work and non-work productivity, as well as greater need for visits to ophthalmologists during the prior year. CONCLUSIONS In this report of the baseline findings of a 5-year natural history study of DED, a striking disease burden is observed with regard to blurred vision, productivity, and visits to eye care practitioners in mild to moderate DED patients compared to normal subjects of similar ages and genders.
