Abstract
INTRODUCTION The lipid layer of the tear film is critical to maintaining the integrity of the tear film and absence in the tear film lipid layer (TFLL) is one of the main causes of evaporative dry eye (EDE) in dry eye disease patients, resulting in excessive evaporation (so-called hyperevaporative dry eye). This study protocol will be designed to assess and compare the effects of intense pulsed light (IPL), heated eye mask (HEM), vectored thermal pulsation system (VTPS) and eyelid massage device (EMD) for improving signs and symptoms of EDE. METHODS AND ANALYSIS Patients with EDE will be randomly divided into IPL, HEM, VTPS and EMD groups and will be followed up for 6 weeks. The primary outcome measure will be non-invasive tear breakup time (NITBUT). The secondary outcome measures will include, TFLL score, meibomian gland quality and expressibility change from baseline conjunctivocorneal staining with fluorescein and lissamine, tear meniscus height, conjunctival hyperaemia (redness score) and ocular surface disease index questionnaire. Additionally, adverse events will be monitored and documented. ETHICS AND DISSEMINATION Ethics approval number: IRB(2023)K019.01. The findings will be shared regardless of the effect's direction. TRIAL REGISTRATION NUMBER NCT05923528.

Abstract
Meibomian glands (MGs), located within the tarsal plate of the eyelid, secrete meibum which is the lipid-rich secretion necessary for stabilizing the tear film and preventing tear evaporation. Changes in the quality and quantity of meibum produced causes MG dysfunction (MGD), the leading cause of evaporative dry eye disease (EDED). MGD is an underdiagnosed disease and it is estimated that, in the US, approximately 70 % of the population over 60 have MGD. Three forms of MGD occur based on their meibum secretion: hyposecretory, obstructive, and hypersecretory MGD. The pathophysiology of MGD remains poorly understood, however aging is the primary risk factor. With age, MGs undergo various age-related changes, including decreased acinar basal cell proliferation, hyperkeratinization, MG atrophy, and eventual MG drop-out, leading to age-related MGD (ARMGD). Additionally, studies have suggested that MGs can suffer inflammatory cell infiltration and changes innervation patterns with aging, which could also contribute towards ARMGD. This review focuses on how the aging process affects the MG, and more importantly, how age-related changes to the MG can lead to MG atrophy and MG drop-out, ultimately leading to ARMGD. This review also highlights the most recent developments in potential therapeutic interventions for ARMGD.

Abstract
Background: Dry eye disease (DED) is a complex ocular surface inflammatory disorder with a multifactorial etiology. Therapies such as intense pulsed light (IPL) and heated eye mask (HEM) have been reported to improve the tear film lipid layer (TFLL) and signs and symptoms of DED. Methods: This randomized study aimed to compare the effects of IPL combined with HEM (IPL+HEM) group, IPL group, and control group in participants with evaporative DED. All participants were examined at baseline (D0), day 21 (D21), day 42 (D42), and day 84 (D84) for noninvasive tear breakup time (NITBUT), TFLL, corneal conjunctival staining (CS), meibomian gland quality (MGQ), meibomian gland expressibility (MGEx), and Ocular Surface Disease Index (OSDI). Results: The mean age of participants was IPL+HEM: 28.06 ± 3.88 years, IPL: 29.88 ± 4.68 years, and control: 28.52 ± 3.77 years. At D84, significant improvements in TFLL (p < 0.05), noninvasive tear breakup time (NITBUT) (p < 0.05), corneoconjunctival staining (CS) (p < 0.05), MGQ (p < 0.05), MGEx (p < 0.05), and OSDI (p < 0.05) were found in the IPL+HEM and IPL groups, whereas the control group had no significant improvements. Furthermore, ΔTFLL significantly correlated with ΔNITBUT (r = -0.678, p < 0.001), ΔCS (r = 0.321, p < 0.001), ΔMGQ (r = 0.669, p < 0.001), ΔMGEx (r = 0.598, p < 0.001), and ΔOSDI score (r = 0.649, p < 0.001). Conclusions: IPL therapy in combination with HEM and IPL therapy only can significantly improve the quality of TFLL and clinically reduce the sign and symptoms of evaporative DED. However, IPL therapy in combination with HEM was found to be more effective than IPL therapy alone.

[PMID: 34840000 DOI: 10.1016/j.jfo.2021.08.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Revised: 07/20/2021] [Accepted: 08/09/2021] [Indexed: 10/19/2022]
Abstract
OBJECTIVES This study aims to evaluate the relationship between application of the MGDRx thermal eyebag and dry eye signs and symptoms in young and older subjects and to compare the results between the two groups. METHODS Thirty young, healthily volunteers between 18 and 31 years of age (23.95±3.94 years) and thirty older subjects between 61 and 90 years of age (77.97±8.11 years) participated in this study. Ocular surface parameters were assessed using the Oculus Keratograph 5M, following the guidelines of the Tear Film and Ocular Surface Dry Eye Workshop II Diagnostic Methodology report. Only subjects with a positive score on at least one questionnaire and an initial Non-Invasive Keratograph Break-Up Time (NIKBUT) under 10seconds were included in the study. After thermal bag self-application in both eyes every day for 2 weeks, the protocol was carried out again. Lid massage was performed after lid warming. Compliance and degree of improvement were also assessed. MAIN RESULTS The young volunteer group showed an improvement in NIKBUT, lipid layer score, upper eyelid gland drop-out percentage and dry eye symptoms over the two week treatment period. Improvements in meibum quality, gland obstruction, telangiectasia scores, and dry eye symptoms were found in the older subjects. Mixed ANOVA revealed better NIKBUT and lipid layer values in the young subjects. Despite the treatment compliance being statistically higher in the older group than in the younger subjects (P=0.002), there were no significant differences in subjective improvement between groups (P=0.097). CONCLUSION Dry eye-related symptoms were improved after thermal bag application, while NIKBUT and lipid layer thickness were improved only in the younger subjects.

Abstract
Wearable electronic devices that can monitor physiological signals of the human body to provide biomedical information have been drawing extensive interests for sustainable personal health management. Here, we report a human pilot trial of a soft, smart contact lens and a skin-attachable therapeutic device for wireless monitoring and therapy of chronic ocular surface inflammation (OSI). As a diagnostic device, this smart contact lens enables real-time measurement of the concentration of matrix metalloproteinase-9, a biomarker for OSI, in tears using a graphene field-effect transistor. As a therapeutic device, we also fabricated a stretchable and transparent heat patch attachable on the human eyelid conformably. Both diagnostic and therapeutic devices can be incorporated using a smartphone for their wireless communications, thereby achieving instantaneous diagnosis of OSI and automated hyperthermia treatments. Furthermore, in vivo tests using live animals and human subjects confirm their good biocompatibility and reliability as a noninvasive, mobile health care solution.

Abstract
OBJECTIVE To determine whether the combination of meibomian gland expression (MGX) with intense-pulsed light (IPL) has a better efficacy to treat meibomian gland dysfunction (MGD) than IPL alone. METHODS One hundred patients with MGD were randomly divided into three groups: MGX, IPL, and IPL+ MGX. Clinical parameters included the Ocular Surface Disease Index (OSDI), tear meniscus height (TMH), noninvasive keratograph tear breakup time (NIBUT), redness, meibomian gland dropout, tear breakup time (TBUT), corneal fluorescent staining (CFS), eyelid margin score, meibomian gland secretion function, and Schirmer I tests were collected before treatment and at 1 and 3 months after treatment. Compare the indexes of each group before and after treatment and also compare the differences of each group on follow-up. RESULTS Compared to the baseline, OSDI, TBUT, and meibomian gland secretion function in IPL group improved throughout the follow-up period (all P < .05) and part of the meibomian gland secretion function increased continuously. OSDI, TBUT, lower eyelid margin scores, and meibomian gland secretion function in IPL + MGX group improved at the both follow-up visits (all P < .05), and continued improvement in meibomian gland secretion function can be observed. Lower meibomian gland dropout and CFS reduced at 1 month and 3 months respectively in IPL ± MGX group (P = .001,P = .001).Compared to IPL group, only CFS has reduction in IPL + MGX group at 1-month (P < .001), CFS, upper and lower MGYCS were improved at the 3 months (P = .037,P = .014, P = .049). CONCLUSIONS MGX may have synergistic effect when combined with IPL therapy, and the effect can last at least 3 months.

Abstract
The most prevalent type of meibomian gland dysfunction (MGD), which is obstructive, is the main cause of evaporative dry eye and is characterized by changes in the meibum composition and duct obstruction. Eyelid hygiene has usually been the most common clinical approach. However, alternative therapies for MGD are emerging on the market. Some warming and humidity devices have led to an improvement in the signs and symptoms in MGD patients. Likewise, eyelid massaging and cleaning devices are also beneficial for ocular signs and symptoms; however, patients usually need more than one session to maintain the therapeutic effect. Thermal pulsation has been reported to be more efficient than other strategies, and the effects can last up to 12 months. Moreover, intense pulsed light therapy has been demonstrated to improve ocular signs and symptoms alone and in combination with other therapies. Proper counseling of clinicians considering MGD status and patient compliance will help patients to undergo the adequate technique that best suits their condition.

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
PURPOSE To determine the effectiveness of the Aurai water propelled, heating Eye Massager (AEM) in managing dry eye disease and its effects on the ocular adnexa. METHODS This prospective, randomised cross-over study enrolled 15 participants (aged 25.8 ± 5.45 years, 5 male). Participants wore a smart watch 24 h a day to track their sleeping cycle and heart rate for 4 weeks, using the AEM twice a day for 2 of those weeks. A cycle of 6 min of a controlled heat and vibration pattern in the morning and another cycle in the evening were applied with the AEM. Primary outcomes of symptomatology (Ocular Surface Disease Index (OSDI) and Symptom Assessment iN Dry Eye (SANDE)), tear film and ocular surface homeostasis markers (osmolarity, non-invasive breakup time (NIKBUT), tear meniscus height (TMH), lipid layer thickness and ocular staining) and safety measures (ocular redness and intraocular pressure), were assessed at baseline, after 2 weeks of AEM use and after 2 weeks of no treatment (in random-sequence). Sleeping tracking (ST) and heart rate/blood oxygen detection over these periods was also assessed. RESULTS There was a significant change in OSDI score from 34.3 ± 19.5 at baseline to 18.8 ± 17.5 after treatment (p = 0.001) and also for the SANDE (5.7 ± 2.4 vs 3.7 ± 2.1; p = 0.001). Heart rate was not affected by treatment (p = 0.956), nor sleep pattern (p = 0.529), but this varied by day (p = 0.001). Tear film and ocular surface homeostasis, the ocular adnexia and safety measures were not affected by treatment (p > 0.05). CONCLUSION The Aurai water propelled Eye Massager may reduce the severity of symptoms of dry eye, but there were no detectable effects on tear stability and ocular surface disease from two weeks use.
