Patient-reported burden of dry eye disease in the UK: a cross-sectional web-based survey

Feasibility of partial-orbit irradiation as a treatment strategy for patients with orbital mucosa-associated lymphoid tissue lymphoma

OBJECTIVE

For early-stage orbital mucosa-associated lymphoid tissue lymphoma (MALToma), radiotherapy (RT) is known to be the treatment of choice. The classical recommended treatment field is the entire ipsilateral orbit, exposing normal orbital structures such as the lacrimal gland and lens, which are sensitive to moderate doses of radiation, to the full treatment dose. Herein we aimed to evaluate the clinical outcomes and dosimetric values in patients with orbital MALToma who received RT.

DESIGN

This study was a retrospective study.

PARTICIPANTS

Forty patients with orbital MALToma treated with curative RT.

METHODS

The patients were classified into the conjunctival RT (n = 23), partial-orbit RT (n = 10), and whole-orbit RT (n = 7) groups. The treatment outcomes and dosimetric values of the orbital structures were reviewed.

RESULTS

We found the 5-year local, contralateral orbit, and overall relapse rates to be 5.0%, 5.9%, and 16.0%, respectively. Local relapse events occurred in 2 patients in the conjunctival RT group. No relapse was observed in the partial-orbit RT group. Whole-orbit RT caused significantly higher rates of dry eyes during treatment. The partial-orbit RT group showed a significantly lower ipsilateral eyeball mean dose and ipsilateral eyelid mean dose than the other groups.

CONCLUSION

Partial-orbit RT showed encouraging clinical, toxicity, and dosimetric outcomes in patients with orbital MALToma and has the potential to be a treatment option for such patients.

New advances in medical management of dry eye: optimizing treatment strategies for enhanced relief

PURPOSE

Dry eye disease (DED) is a prevalent ocular surface disease that is conventionally characterized by tear film hyperosmolarity and instability. This review presents a summarized classification of DED, followed by a comprehensive discussion of the most recent topical and systemic medications and clinical recommendations for selecting the most appropriate option for each patient.

METHODS

An extensive literature search was conducted on electronic databases, such as PubMed, Scopus, and Web of Science, using keywords including "dry eye syndrome," "ocular surface disease," "medical management," "artificial tears," "topical immunomodulators," and "meibomian gland dysfunction."

RESULTS

The underlying reasons for DED can range from insufficient aqueous tear production to increased tear evaporation. Recent literature has provided a more in-depth understanding of the pathophysiology of DED by examining the tear film's lipid, aqueous, and mucin layers. However, despite these advancements, medical management of patients with symptomatic DED has not fully reflected this modernized knowledge of its pathophysiology.

CONCLUSION

To develop a rationalized strategy for treating DED, it is crucial to have updated knowledge of therapeutic options, their mechanisms of actions, and indications based on the DED type and underlying causes.

Optometrists need to incorporate their understanding of the impact of dry eye disease in their patient management

SIGNIFICANCE

The impact of dry eye disease on patients' daily lives is understood by optometrists, but they seldom use this understanding in their patient management.

PURPOSE

Dry eye disease can significantly impact a person's daily life and is known to cause psychological symptoms. Treating and managing patients with dry eye disease can be challenging, as an approach based solely on signs is unlikely to reflect patients' true burden. Because optometrists play a crucial role in the care of dry eye disease patients, it is necessary to examine their awareness of the negative impact of dry eye disease on patients' daily lives and how they manage this during their consultation time, including diagnosis and management.

METHODS

This study has an exploratory, qualitative research design. Twelve semistructured online interviews were conducted with optometrists in second-line eye care through a convenience sample. The interviews were recorded, transcribed verbatim, and analyzed after a thematic analysis.

RESULTS

The main findings were that few optometrists actively asked about patients' perceived burden, many optometrists did not mention all the possible treatment options or practical advice that could benefit dry eye disease patients, and few were aware of the possible help that other health care providers could provide, besides the optometrist.

CONCLUSIONS

Dutch optometrists are aware of the impact that dry eye disease can have on their patients' daily lives, but seldom use this information as part of their management plan.

Electroacupuncture for mild-to-moderate dry eye: study protocol for a multicentre, randomised, single-blind, sham-controlled trial

INTRODUCTION

Dry eye (DE) is a multifactorial ocular surface disease causing considerable medical, social and financial implications. Currently, there is no recognised long-term, effective treatment to alleviate DE. Clinical evidence shows that electroacupuncture (EA) can improve DE symptoms, tear secretion and tear film stability, but it remains controversial whether it is just a placebo effect. We aim to provide solid clinical evidence for the EA treatment of DE.

METHODS AND ANALYSIS

This is a multicentre, randomised, sham-controlled trial. A total of 168 patients with DE will be enrolled and randomly assigned to EA or sham EA groups to receive 4-week consecutive treatments and follow-up for 24 weeks. The primary outcome is the change in the non-invasive tear break-up time (NIBUT) from baseline to week 4. The secondary outcomes include tear meniscus height, the Schirmer I test, corneal and conjunctival sensation, the ocular surface disease index, corneal fluorescein staining, the numerical rating scale and the Chinese DE-related quality of life scale.

ETHICS AND DISSEMINATION

The trial protocol and informed consent were approved by the Ethics Committee of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine Affiliated to Shanghai University of Traditional Chinese Medicine (identifier: 2021-119), Shanghai Eye Disease Prevention and Treatment Center (identifier: 2022SQ003) and Eye and ENT Hospital of Fudan University (identifier: 2022014).

Correlation and Level of Agreement between the Ocular Surface Disease Index and the Symptom Assessment in Dry Eye Questionnaires: A Survey-Based Study

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.

Relationship between clinical parameters and quality of life in primary Sjögren's Syndrome: a prospective study

OBJECTIVES

To quantify the impact of dry eye disease (DED) on health and vision related quality of life (HR-QOL, VR-QOL) in patients with Primary Sjögren's Syndrome (pSS).

METHODS

Thirty-four participants with a confirmed diagnosis of pSS as per the 2016 ACR EULAR criteria participated. Main outcome measures included ocular surface parameters and HR-QOL and VR-QOL questionnaires. Clinical examination included visual acuity, Schirmer I testing, ocular surface staining (OSS) and measurement of tear film breakup time. The questionnaires included Ocular Surface Disease Index, National Eye Institute Visual Function Questionnaire-25, Short Form-36 (SF-36) and EULAR Sjogren's Syndrome Patient Reported Index.

RESULTS

Despite the majority of participants (28 female, 6 male, mean age 61.3 years) having attained LogMAR 0.3 or better visual acuity, participants scored low on VR-QOL measures, representing DED related fluctuation in functional vision. All participants suffered from moderate to severe DED. OSS did not correlate with DED symptoms or QOL parameters. Lubricant usage and symptom severity had a statistically moderate to strong negative correlation with VR-QOL and HR-QOL. This was most evident in relation to physical and physiological wellbeing. Compared with normative data, participants had a lower HR-QOL in all scales of the SF-36 ((MD = 9.91 ± 5.16); t(7) = 5.43, p = 0.001).

CONCLUSIONS

Participants with pSS have a lower perceived QOL especially in relation to physical and mental wellbeing, correlating to severity of DED symptoms and treatment burden. Clinical signs do not align with symptoms. Therefore, clinicians should remain cognisant, adjusting treatment in accordance with patient reported perceptions.

Patient-reported burden and overall impact of dry eye disease across eight European countries: a cross-sectional web-based survey

OBJECTIVE

Dry eye disease (DED) is a multifactorial disease involving the tears and ocular surface. It impacts a patient's quality of life (QoL) and ability to perform daily activities. This study assessed the burden of self-reported DED among adults in eight European countries.

DESIGN

Online cross-sectional survey.

SETTING

General population in France, Italy, Germany, Greece, the Netherlands, Portugal, Spain and Sweden.

PARTICIPANTS

Adults aged ≥18 years with (n=6084) and without (n=6161) self-reported DED were recruited via emails and screened.

MAIN OUTCOME MEASURES

All participants completed National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25) and EuroQol-5 Dimension-5 Level Questionnaire (EQ-5D-5L). All DED participants completed the Eye Dryness Score (EDS) Visual Analogue Scale, and Ocular Comfort Index and Work Productivity and Activity Impairment Questionnaire: Specific Health Problem questionnaires. In addition, half of the respondents with DED completed Survey A (Impact of Dry Eye on Everyday Life) and the other half completed Survey B (Standard Patient Evaluation of Eye Dryness Questionnaire) and Dry Eye Questionnaire-5.

RESULTS

Participants with self-reported DED had lower functional vision and lower overall health status than participants without self-reported DED as measured by the NEI-VFQ and EQ-5D-5L, respectively.Increasing self-reported DED severity as measured by the EDS was shown to correspond with worse symptom severity/frequency, lower functional vision, higher impact on work productivity, daily activities and QoL.

CONCLUSION

This study showed that patients' reported burden of self-reported DED was similar across the eight European countries. Those with self-reported DED reported lower health status and functional vision compared to those without self-reported DED and these parameters worsen with increasing disease severity.

Systemic Lupus Erythematosus and Risk of Dry Eye Disease and Corneal Surface Damage: A Population-Based Cohort Study

Systemic lupus erythematosus (SLE) potentially involves multiple parts of the ocular system, including the lacrimal glands and the cornea. The present study sought to assess the risk of aqueous-deficient dry eye disease (DED) and corneal surface damage in patients with SLE. We conducted a population-based cohort study using Taiwan's National Health Insurance research database to compare the risks of DED and corneal surface damage between subjects with and without SLE. Proportional hazard regression analyses were used to calculate the adjusted hazard ratio (aHR) and 95% confidence interval (CI) for the study outcomes. The propensity score matching procedure generated 5083 matched pairs with 78,817 person-years of follow-up for analyses. The incidence of DED was 31.90 and 7.66 per 1000 person-years in patients with and without SLE, respectively. After adjusting for covariates, SLE was significantly associated with DED (aHR: 3.30, 95% CI: 2.88-3.78, p < 0.0001) and secondary Sjögren's syndrome (aHR: 9.03, 95% CI: 6.86-11.88, p < 0.0001). Subgroup analyses demonstrated that the increased risk of DED was augmented among patients with age < 65 years and female sex. In addition, patients with SLE had a higher risk of corneal surface damage (aHR: 1.81, 95% CI: 1.35-2.41, p < 0.0001) compared to control subjects, including recurrent corneal erosion (aHR: 2.98, 95% CI: 1.63-5.46, p = 0.0004) and corneal scar (aHR: 2.23, 95% CI: 1.08-4.61, p = 0.0302). In this 12-year nationwide cohort study, we found that SLE was associated with increased risks of DED and corneal surface damage. Regular ophthalmology surveillance should be considered to prevent sight-threatening sequelae among patients with SLE.

Matching-adjusted indirect comparison of phase 3 clinical trial outcomes of OC-01 (varenicline solution) nasal spray and lifitegrast 5% ophthalmic solution for the treatment of dry eye disease

BACKGROUND: Matching-adjusted indirect comparison (MAIC) is a methodology for cross-study comparisons after adjusting for baseline characteristic imbalances. It is a comparative analytical approach used across therapeutic areas absent head-to-head trial outcomes. OBJECTIVE: To compare the efficacy of OC-01 (varenicline solution) 0.03 mg nasal spray (OC-01 VNS) to lifitegrast 5% ophthalmic solution on tear production and patient-reported eye dryness in patients with dry eye disease (DED) using data from phase 3 clinical trials via MAIC analysis. METHODS: Individual patient data (IPD) from the phase 3 registrational trial of OC-01 VNS and aggregate data from 2 phase 3 trials of lifitegrast in the publicly available XIIDRA New Drug Application were used. Using unanchored MAIC methods, IPD were weighted on clinically relevant baseline variables (age, race, sex, baseline Schirmer's test score [STS], and Eye Dryness Score [EDS]) to produce weighted OC-01 VNS datasets matched to the same lifitegrast datasets' variables. Least-squares (LS) mean change from baseline (CFB) in STS for OC-01 VNS was calculated using the identical analysis of covariance model and covariates used to calculate the same values for lifitegrast in the XIIDRA New Drug Application and was then compared. LS mean EDS (based on a 100- point Visual Analogue Scale) was compared via analysis of covariance in the weighted OC-01 VNS and lifitegrast datasets. OC-01 VNS at 2 and 4 weeks compared to lifitegrast data at 2 and 6 weeks. RESULTS: Data from 511 subjects (n = 260 treated; 251 vehicle control [VC]) in the OC-01 VNS phase 3 trial, 588 (n = 293 treated, 295 VC) in the lifitegrast phase 3 OPUS-1 trial, and 718 (n = 358 treated, 360 VC) in the lifitegrast phase 3 OPUS-2 trial were analyzed. The LS mean STS CFB for OC-01 VNS at 2 and 4 weeks was significantly greater than that for lifitegrast at 2 and 6 weeks in OPUS-1 and OPUS-2 (P < 0.0001 for all comparisons). The LS mean EDS CFB for OC-01 VNS at 2 and 4 weeks was significantly greater than that for lifitegrast at 2 and 6 weeks in OPUS-1 (P < 0.0001 for both comparisons) and at 4 weeks vs lifitegrast at 6 weeks in OPUS-2 (P < 0.0001). CONCLUSIONS: This MAIC analysis demonstrates OC-01 VNS produced significantly greater improvement in mean STS and comparable or greater improvement in EDS compared with lifitegrast in phase 3 trials. These findings suggest a potentially greater magnitude of improvement achieved with OC-01 VNS compared with lifitegrast for the treatment of DED within the conditions of the analysis methodology.

Management of inflammation in dry eye disease: Recommendations from a European panel of experts

Introduction

Early initiation of anti-inflammatory therapies is recommended for dry eye disease (DED) to break the vicious cycle of pathophysiology. However, there is limited guidance on how to implement topical ciclosporin (CsA) and corticosteroid treatment into clinical practice. This expert-led consensus provides practical guidance on the management of DED, including when and how to use topical CsA.

Methods

A steering committee (SC) of seven European DED experts developed a questionnaire to gain information on the unmet needs and management of DED in clinical practice. Consensus statements on four key areas (disease severity and progression; patient management; efficacy, safety and tolerability of CsA; and patient education) were generated based on the responses. The SC and an expanded expert panel of 22 members used a nine-point scale (1  =  strongly disagree; 9  =  strongly agree) to rate statements; a consensus was reached if ≥75% of experts scored a statement ≥7.

Results

A stepwise approach to DED management is required in patients presenting with moderate corneal staining. Early topical CsA initiation, alone or with corticosteroids, should be considered in patients with clinical risk factors for severe DED. Patient education is required before and during treatment to manage expectations regarding efficacy and tolerability in order to optimise adherence. Follow-up visits are required, ideally at Month 1 and every 3 months thereafter. Topical CsA may be continued indefinitely, especially when surgery is required.

Conclusion

This consensus fills some of the knowledge gaps in previous recommendations regarding the use of topical corticosteroids and CsA in patients with DED.

Differentiating primary dry eye disease from ocular neuropathic pain: implications for symptom management

CLINICAL RELEVANCE

Eyecare practitioners' management of ocular surface disease is essential in managing increasing dry eye disease (DED) presentations including ocular neuropathic pain (ONP). Topical Proxymetacaine offers a simple, readily available and practical method of detecting ONP in practice and can be used to differentiate ONP from DED by eyecare practitioners, when accompanied with an anterior segment examination.

BACKGROUND

Differentiating DED from ONP presents a significant opportunity to eyecare providers, allowing appropriate treatment choices for more adequate symptom control, greater patient satisfaction, and reduced emergent re-presentations. This study aims to differentiate patients presenting with DED symptoms into DED or ONP using a simple diagnostic tool, which can be used in practice to allocate appropriate treatment options for the patient's respective condition. A comparison of the prevalence of presentations of ONP presenting with DED symptoms in hospital ophthalmology settings and in optometric primary care settings will also be made.

METHODS

Patients with symptoms of DED were opportunistically recruited as they presented to ophthalmology outpatient clinics and primary care optometric services. Patients were then categorised as DED, ONP, or mixed DED/ONP based on their subjective response 30 seconds post-Proxymetacaine Hydrochloride 2% instillation.

RESULTS

Twenty-one patients were recruited, including 12 patients from ophthalmologic outpatient clinics and nine patients from primary care optometric services. Twelve patients were identified to have primary DED, while nine patients were identified to have ONP. 43% of patients presenting with DED symptoms had features of neuropathic pain in ophthalmologic outpatient presentations compared to 44% of patients in primary care optometric services.

CONCLUSION

Categorising DED and ONP patients by their response to Proxymetacaine can be used as a simple diagnostic tool in guiding future patient management and can be indicative of their potential response to topical therapies. The use of topical Proxymetacaine and the resultant change in ocular pain score can facilitate selection of patients who may benefit from centrally acting neuropathic pain agents over topical ocular therapy.

Chinese Version of the Vision-Related Quality of Life (NEI-VFQ-25) among Patients with Various Ocular Disorders: A Pilot Study

Background and Objectives: Subjective visual function is currently becoming an increasing appreciation in assessing the health-related quality of life. This study aimed to assess the vision-related quality of life (VRQOL) among patients with refractive errors, keratoconus, senile cataract, and age-related macular degeneration (AMD) using the Chinese version of the National Eye Institute Visual Function Questionnaire 25 (NEI-VFQ-25). Materials and Methods: The questionnaire of NEI-VFQ-25 was filled out in a clinical setting or by telephone/mail. Univariate and multivariate analyses were used to determine which factors are associated with the NEI-VFQ-25. Results: From June 2018 to January 2019, 28 patients with refractive error, 20 patients with keratoconus, 61 with senile cataracts, and 17 with AMD completed the questionnaire NEI-VFQ-25. There were significant differences in the NEI-VFQ-25 subscale of general vision (p = 0.0017), ocular pain (p = 0.0156), near activities (p = 0.0002), vision-specific social functioning (p = 0.007), vision-specific mental health (p = 0.0083), vision-specific dependency (p = 0.0049), color vision (p < 0.0001), peripheral vision (p = 0.0065), and total score (p < 0.0001) among four disease groups, respectively. The multiple linear regression revealed that the best-corrected visual acuity (BCVA) and disease group were important factors of the total NEI-VFQ-25. After adjusting for BCVA, patients with AMD had a worse total NEI-VFQ-25 score than patients with refractive error, keratoconus, or senile cataracts. Conclusions: Among the patients with four ocular disorders and a broad vision spectrum from normal, partial sight, low vision to legal blindness, the BCVA of their better eye was the most important factor in the VRQOL.

Dry Eye Disease Among Mongolian and Han Older Adults in Grasslands of Northern China: Prevalence, Associated Factors, and Vision-Related Quality of Life

Purpose: Dry eye disease (DED) is projected to have increasing public health burden in China with the aging population. No published studies on the epidemiology of DED have been found in grasslands. We estimated DED prevalence among older adults living in grasslands of northern China and investigated its associated factors and impact on vision-related quality of life (VR-QoL). Methods: A multistage cluster random sampling technique was used to select Mongolian and Han participants aged over 40 from November 2020 to May 2021 in this area. An assessment of DED was performed with Ocular Surface Disease Index (OSDI) questionnaire, Schirmer's I test (ST), and Tear film break up time (TBUT). All the participants completed the Chinese version of National Eye Institute Visual Function Questionnaire (NEI-VFQ-25) assessing VR-QoL. Results: Of the 1,400 enumerated residents, 1,287 were examined. The overall age and gender standardized prevalence of DED was 34.5%, of which, 32.6% of Mongolian and 35.4% of Han had DED. In a multivariate model, statistically significant associations were found with advancing age [odds ratio (OR) 1.03, 95% confidence interval (CI) 1.02-1.04], female gender (OR 1.32, 95% CI 1.04-1.68), smoking (OR 0.7, 95% CI 0.5-0.98), anti-fatigue eye-drop use (OR 0.56, 95% CI 0.41-0.77), milk product intake (OR 0.55, 95% CI 0.39-0.77), number of household members (OR 0.8, 95% CI 0.72-0.88). DED was associated with lower scores on VR-QoL (β= -0.14, P < 0.01). Similar results were observed when analyses were stratified by ethnicity. Conclusions: The novelty-associated factors for DED in the grasslands area were anti-fatigue eye drop use, milk product intake, and number of household members. DED and its components were associated with VR-QoL. Further prospective studies are needed to confirm these findings.
