Defining the needs and preferences of patients with dry eye disease

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.

The Ins and Outs of Clusterin: Its Role in Cancer, Eye Diseases and Wound Healing

Clusterin (CLU) is a glycoprotein originally discovered in 1983 in ram testis fluid. Rapidly observed in other tissues, it was initially given various names based on its function in different tissues. In 1992, it was finally named CLU by consensus. Nearly omnipresent in human tissues, CLU is strongly expressed at fluid-tissue interfaces, including in the eye and in particular the cornea. Recent research has identified different forms of CLU, with the most prominent being a 75-80 kDa heterodimeric protein that is secreted. Another truncated version of CLU (55 kDa) is localized to the nucleus and exerts pro-apoptotic activities. CLU has been reported to be involved in various physiological processes such as sperm maturation, lipid transportation, complement inhibition and chaperone activity. CLU was also reported to exert important functions in tissue remodeling, cell-cell adhesion, cell-substratum interaction, cytoprotection, apoptotic cell death, cell proliferation and migration. Hence, this protein is sparking interest in tissue wound healing. Moreover, CLU gene expression is finely regulated by cytokines, growth factors and stress-inducing agents, leading to abnormally elevated levels of CLU in many states of cellular disturbance, including cancer and neurodegenerative conditions. In the eye, CLU expression has been reported as being severely increased in several pathologies, such as age-related macular degeneration and Fuch's corneal dystrophy, while it is depleted in others, such as pathologic keratinization. Nevertheless, the precise role of CLU in the development of ocular pathologies has yet to be deciphered. The question of whether CLU expression is influenced by these disorders or contributes to them remains open. In this article, we review the actual knowledge about CLU at both the protein and gene expression level in wound healing, and explore the possibility that CLU is a key factor in cancer and eye diseases. Understanding the expression and regulation of CLU could lead to the development of novel therapeutics for promoting wound healing.

Effect of OTX-101 in Patients with Dry Eye Disease at Day 14 of Treatment: Ocular Surface Endpoint Results from the Phase 2b/3 Clinical Trial

Dry eye disease (DED) is a multifactorial disorder characterized by loss of tear film homeostasis, which initiates a cycle of ocular surface inflammation and damage. As ocular discomfort symptoms associated with DED can decrease quality of life, affected patients prefer treatments that rapidly improve the underlying disease process. OTX-101 0.09% (CEQUA®) is indicated to increase tear production in patients with DED. The current analysis assessed early efficacy of OTX-101 0.09% in adult patients with bilateral DED by evaluating ocular surface endpoints after 14 days of treatment in the phase 2b/3 trial. In this randomized, double-masked, vehicle-controlled, dose-ranging study, patients received one drop of OTX-101 0.05%, OTX-101 0.09%, or vehicle per eye twice daily for 84 days. Corneal staining, conjunctival staining, tear breakup time (TBUT), and modified Symptom Assessment iN Dry Eye (SANDE) total global symptom score were assessed at baseline and Days 14, 28, 42, 56, and 84/early discontinuation. Overall, 455 patients were randomized (OTX-101 0.05%, n=151; OTX-101 0.09%, n=152; vehicle, n=152); only baseline and Day 14 results for the approved OTX-101 0.09% formulation and vehicle are presented. Least squares (LS) mean (standard error [SE]) change from baseline in conjunctival staining score was -1.3 (0.1) for OTX-101 and -1.0 (0.1) for vehicle. LS mean (SE) change from baseline in corneal staining score was -1.1 (0.17) for OTX-101 and -0.7 (0.17) for vehicle. LS mean (SE) change from baseline in TBUT was 0.52 (0.15) for OTX-101 and 0.36 (0.15) for vehicle. LS mean (SE) change from baseline in modified SANDE total global symptom score was -4.93 (1.54) for OTX-101 and -9.1 (1.54) for vehicle. OTX-101 0.09% demonstrated a numerically greater treatment effect compared with vehicle in conjunctival staining, corneal staining, and TBUT after 14 days.

Effect of sodium hyaluronate eye drops combined with tobramycin, dexamethasone and pranoprofen eye drops in the treatment of dry eye after phacoemulsification

Purpose

To investigate the clinical effect of sodium hyaluronate eye drops combined with tobramycin, dexamethasone, and pranoprofen eye drops in the treatment of dry eye after phacoemulsification.

Methods

Medical records of 188 patients with dry eye after phacoemulsification, treated in our hospital from August 2020 to August 2021, were included and divided into groups based on the type of dry eye treatment. Patients in the control group (n = 90) were treated with tobramycin, dexamethasone, and pranoprofen eye drops. Patients in the test group (n = 98) were treated with sodium hyaluronate, tobramycin, dexamethasone, and pranoprofen eye drops. The tear secretion test (TST), film rupture time (BUT), corneal fluorescence staining (FS) score, levels of interleukin (IL)-6, and tumor necrosis factor (TNF)-α before the treatment and at 1 month follow-up, the overall total effective rate and the number of completely cured cases were compared between the two groups. Multiple linear regression was used to calculate coefficients for predicting clinical variables. Ordinal logistic regression was used to compute coefficients and odds ratios for predicting effective scores.

Results

The total effective rate in the observation group (99%) was significantly higher than that in the control group (80.00%). After the treatment, the TST and BUT indexes of the observation group were higher compared to the control group, and the FS score of the observation group was lower than that of the control group. TNF-α and IL-6 levels of the observation group were lower compared to the control group. Logistic regression analysis demonstrated that the differences in the effective rate and clinical variables between the two groups remained significant after adjusting for the effect of age.

Conclusion

A combination of sodium hyaluronate, tobramycin, dexamethasone, and pranoprofen eye drops for the treatment of dry eye after phacoemulsification can improve the curative effect, reduce corneal fluorescein staining and inflammatory factor index levels compared to the treatment regimen lacking sodium hyaluronate eye drops.

Patient perspectives on dry eye disease and chronic ocular surface pain: Insights from a virtual community-moderated dialogue

PURPOSE

To understand patients' perspectives on living with dry eye disease (DED), and on the unmet needs in DED and chronic ocular surface pain (COSP) management.

METHODS

A moderated, structured discussion with patients with ocular surface diseases and healthcare professionals (HCPs) was conducted using a virtual platform to capture patients' journey with DED, their opinion on unmet needs, and design and conduct of clinical trials in DED and COSP.

RESULTS

Nine participants, including four patient representatives from patient organisations, one ophthalmologist and one optometrist participated in the discussion. Patients had DED of varying severity and aetiology; three patients had Sjögren's. Over 4 weeks, 785 posts were entered on the platform. Prior to diagnosis, patients rarely associated their symptoms with DED. Convenience and symptomatic relief scored higher than treating the disease. Patients expressed the need for plain language information and dialogue with knowledgeable and sensitive HCPs. Online forums and social media were suggested as key recruitment resources, whereas convenience and safety concerns were highlighted as main barriers to enrolment. The need for the inclusion of outcome measures that have a real impact on patients' experience of their condition was highlighted. Both target product profiles were received positively by participants, highlighting the twice-daily dosing regimen and convenience of the products. Participants acknowledged the value of digital tools and suggested the need to feel valued post-trial.

CONCLUSIONS

This moderated dialogue provided actionable insights on the unmet needs in DED and useful inputs for consideration when designing future clinical trials for DED and COSP.

Living with presbyopia: experiences from a virtual roundtable dialogue among impacted individuals and healthcare professionals

BACKGROUND

Presbyopia is a common progressive vision disorder characterised by an inability to focus on near objects. The emergence of newer treatment options in addition to spectacles or contact lenses highlights the importance of assessing patient/user preferences.

METHODS

People with presbyopia and healthcare professionals (HCPs) took part in a moderated, structured discussion of specific questions on a virtual advisory-board platform. The objective was to better understand unmet needs and the experience of living with the condition. Closed and open questions were included.

RESULTS

Nine individuals (age 40 to 70 years) with presbyopia participated, from Australia, China, France, Italy, Ireland, Japan and the US. One ophthalmologist and one optometrist represented the perspective of HCPs. Over two weeks, 621 posts were entered on the platform. There was widespread agreement that the often stated association between age and presbyopia was unfortunate. Some participants had developed presbyopia at 30-45 years of age. What is more, the association with age was seen as implying a natural process, reducing the incentive to treat. Instead there was a call for an action-oriented view of presbyopia as a condition which may be effectively treated in the future. All participants experienced dealing with presbyopia as burdensome, affecting quality of life to varying degrees. When considering new treatments, convenience was the most important factor. The option to administer drops when needed was considered favourable, but short-acting treatments may not reduce inconvenience compared with spectacles. Participants viewed a therapy that targets the underlying cause of the condition favourably compared with symptomatic treatment. Side effects would severely reduce the appeal of drops. For clinical trials in presbyopia, patient-reported outcomes should be mandatory and need adequately to capture quality of life. Studies in presbyopia must be designed to minimise the inconvenience to participants in order to counter the risk of high drop-out rates.

CONCLUSIONS

The interactive format provided insights into living with presbyopia, particularly the negative impact on quality of life, subjects' openness to new therapies, and the need to move away from considering the condition an unavoidable and intractable consequence of ageing.

Patient Preferences to Assess Value IN Gene Therapies: Protocol Development for the PAVING Study in Hemophilia

Introduction: Gene therapies are innovative therapies that are increasingly being developed. However, health technology assessment (HTA) and payer decision making on these therapies is impeded by uncertainties, especially regarding long-term outcomes. Through measuring patient preferences regarding gene therapies, the importance of unique elements that go beyond health gain can be quantified and inform value assessments. We designed a study, namely the Patient preferences to Assess Value IN Gene therapies (PAVING) study, that can inform HTA and payers by investigating trade-offs that adult Belgian hemophilia A and B patients are willing to make when asked to choose between a standard of care and gene therapy.

Methods and Analysis: An eight-step approach was taken to establish the protocol for this study: (1) stated preference method selection, (2) initial attributes identification, (3) stakeholder (HTA and payer) needs identification, (4) patient relevant attributes and information needs identification, (5) level identification and choice task construction, (6) educational tool design, (7) survey integration, and (8) piloting and pretesting. In the end, a threshold technique survey was designed using the attributes “Annual bleeding rate,” “Chance to stop prophylaxis,” “Time that side effects have been studied,” and “Quality of Life.”

Ethics and Dissemination: The Medical Ethics Committee of UZ KU Leuven/Research approved the study. Results from the study will be presented to stakeholders and patients at conferences and in peer-reviewed journals. We hope that results from the PAVING study can inform decision makers on the acceptability of uncertainties and the value of gene therapies to patients.

Trends in Dry Eye Disease Management Worldwide

Dry eye disease (DED) is a condition frequently encountered in ophthalmology practice worldwide. The purpose of this literature review is to highlight the worldwide trends in DED diagnosis and therapy amongst practitioners and determine if a more uniform approach to manage this multifactorial condition has developed over the past two decades. A manual literature search utilizing PubMed was conducted to obtain papers with survey results relating to ophthalmology and optometry diagnosis and treatment of dry eye from January 2000 to January 2020. This did not include data from clinical trials as we were only interested in community clinical practice trends. The terms “dry eye” and “survey” were searched in combination with one or more of the following words or phrases: prevalence, diagnosis, treatment, therapy, etiology, risk factors, therapy, and quality of life. Papers were selected based on their direct applicability to the subject and were only included if they contained relevant survey data from community practitioners. The available literature suggests common trends worldwide in the diagnosis and treatment of DED. These trends have not modified substantially over the past two decades. Practitioner education on the benefits of measuring tear film homeostasis could increase its use as a diagnostic tool to complement current tools. Of the results found, 75% of the papers were published after 2006 and only one paper after 2017. More recent survey results are required to determine if research into DED pathophysiology is altering the current trend in DED management.
