Abstract
Following viral infection, the innate immune system senses viral products, such as viral nucleic acids, to activate innate defence pathways, leading to inflammation and apoptosis, control of cell proliferation, and consequently, threat to the whole body. The ocular surface is exposed to the external environment and extremely vulnerable to viral infection. Several studies have revealed that viral infection can induce inflammation of the ocular surface and reduce tear secretion of the lacrimal gland (LG), consequently triggering ocular morphological and functional changes and resulting in dry eye disease (DED). Understanding the mechanisms of DED caused by viral infection and its potential therapeutic strategies are crucial for clinical interventional advances in DED. This review summarizes the roles of viral infection in the pathogenesis of DED, applicable diagnostic and therapeutic strategies, and potential regions of future studies.

J Cataract Refract Surg 2024; 50:644-650. [PMID: 38334413 DOI: 10.1097/j.jcrs.0000000000001423] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Accepted: 02/03/2024] [Indexed: 02/10/2024]
Abstract
This is a pooled analysis from 2 phase III clinical trials investigating a water-free topical cyclosporine 0.1% for the treatment of moderate to severe dry eye. The analyses included 1162 patients: 35% with cataract, 20% with pseudophakia, and 45% without cataract. Demographics or baseline characteristics were comparable across groups except for age and vision. The cyclosporine-treated patients achieved large mean improvements from baseline by day 15: -3.7 in patients without cataract, -3.2 in patients with cataract, and -3.1 in pseudophakic patients. These improvements were statistically significantly higher compared with the respective vehicle groups. In the cataract subgroup, 59% of patients treated with cyclosporine achieved ≥3 grade improvements in corneal staining score, as early as day 15. The magnitude of the effect and early onset of action make this new cyclosporine solution a promising candidate for preoperative management of ocular surface in patients undergoing cataract surgery.

Abstract
OBJECTIVES Dry eye is a common condition that can decrease the quality of life. This survey-based study of persons with dry eye investigated self-reported treatments (initial, current), out-of-pocket expenses, time spent on self-management, sources of care, and sources of information about their condition. METHODS Online dry eye newsletters and support groups were emailed a link to an electronic survey asking members to participate. Survey respondents were not required to answer every question. RESULTS In total, 639 persons with self-reported dry eye responded (86% women, 14% men [n=623]; mean ± SD age, 55 ± 14 years [n=595]). Artificial tears were the most reported intervention (76% initially, 71% currently). The median (interquartile range) out-of-pocket treatment cost annually was $500 ($200-$1,320 [n=506]). In addition, 55% (n=544) estimated 5 to 20 min daily on self-management; 22% spent an hour or more. Ophthalmologists provided most dry eye care (67%, n=520). Only 48% (n=524) reported that their primary source of dry eye information came from their eye care clinician. CONCLUSIONS Artificial tears are the primary treatment for dry eye. Ophthalmologists provide most dry eye care, but half of patients report that their eye care provider is not their primary source of information. Almost one fourth of patients spend an hour or more daily on treatments.

Abstract
PURPOSE To determine the changes in keratometry measurements and refraction in patients having the thermo-mechanical periorbital skin treatment, Tixel®, to treat dry eye disease (DED). METHODS A multi-centre, prospective, non-masked study was conducted. DED patients were recruited in 3 international centres and were evaluated in 5 visits separated by an interval of 2 weeks except for the last visit which took place after 18 weeks from visit 1. The same clinical examination was performed at all visits: OSDI questionnaire, tear stability, keratometry, best corrected visual acuity and refraction. Tixel® treatment was applied at the first 3 visits. RESULTS 89 participants (24 males/65 females; mean age: 55.0 ± 14.2 years) were included: 20 presented moderate DED symptoms and 69 severe DED symptoms. Significant differences were found for the spherocylindrical refraction (vector analysis) between visit 1 and visits 2 and 3. Following cumulative analysis, 11.86 % and 16.94 % of participants had more than 0.5 dioptre (D) change in mean keratometry and keratometric astigmatism, respectively, at 3 months post-treatment. A total of 5.40 % had a sphere and cylinder change greater than 0.50D and 16.21 % had the axis changed more than 10 degrees (vector analysis). These changes were particularly significant in patients with severe DED symptoms. CONCLUSIONS Keratometry readings and refraction can change following thermo-mechanical skin treatment for DED, especially in those patients with severe DED symptoms. This should be considered as potential errors in intraocular lens calculations may be induced.

Heliyon 2024; 10:e31181. [PMID: 38807885 PMCID: PMC11130690 DOI: 10.1016/j.heliyon.2024.e31181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Revised: 05/06/2024] [Accepted: 05/12/2024] [Indexed: 05/30/2024] Open
Abstract
Purpose This study aimed to explore the practices of optometrists in Hong Kong towards diagnosing and managing dry eye disease (DED). Methods From September 2021 to March 2022, an online questionnaire was distributed to optometrists in Hong Kong through several professional associations. The questionnaire included questions about the importance and usefulness of various diagnostic tests, as well as inquiries about management strategies and recommended follow-up schedules for DED. Responses were compared between optometrists who were more or less proactive in continuing education to identify potential differences. Results The analysis included 68 valid responses. Sixty-one of them were Part 1 optometrists that represents 5.5 % of registered Part 1 optometrists back in 2022. Assessment of clinical symptoms was the most commonly performed investigation (93 %) and considered the most important (75 %) procedure in DED assessments, followed by corneal staining and fluorescein tear break-up time. Traditional diagnostic tests were preferred over newer methods, such as osmolarity, which were not yet commonly used. Unpreserved lubricants (90 %) and lid hygiene (63 %) were the primary treatments recommended for mild DED. Optometrists who had more experience and frequent participation in continuing education were more confident in diagnosing and managing DED, and more likely to recommend omega-3 supplements for moderate DED. Conclusion The diagnostic and management strategies of optometrists in Hong Kong were generally consistent with the recommendations of the Dry Eye Workshop II report. However, standardized DED questionnaires and newer diagnostic tools were not commonly used. Evidence-based optometric care for dry eye management should be encouraged in Hong Kong optometric practice.

Abstract
PURPOSE To evaluate the role of topical cyclosporine A 1% (CsA) as an adjuvant therapy in patients with acute Stevens-Johnson syndrome (SJS). METHODS This is a randomised controlled trial in which 44 patients (88 eyes) with acute SJS, presenting within 3 months from the onset of the disease, were enrolled and randomised. Group A (n=44 eyes) patients received treatment with topical CsA 1% along with standard therapy consisting of topical corticosteroids, antibiotics and lubricants. Group B (n=44 eyes) patients received topical saline drops in combination with standard therapy. Various ocular surface parameters were assessed at baseline and the 6-month follow-up. RESULTS The mean age of patients (years) was 23.9±15.1 in the CsA group and 26.0±18.7 in the control group (p=0.6840). The mean time from disease onset to presentation (days) was 17.0±14.0 and 12.9±11.3 in CsA and control groups, respectively (p=0.1568). At presentation, the mean grades of severity scores of various parameters were comparable. At 6 months, both groups showed a significant improvement in the mean severity grades of conjunctival hyperaemia (A, p=0.001; B, p=0.0001), mucocutaneous junction involvement (A, p=0.001; B, p=0.0001) and meibomian gland involvement (A, p=0.0471; B, p=0.006). Compared with baseline, the grades of corneal keratinisation (baseline, 0.48±0.7; 6 months, 1.02±0.8; p=0.0015) and neovascularisation (baseline, 1.07±1.2; 6 months, 1.57±1.0; p=0.0412) worsened after 6 months of CsA therapy. Intergroup comparison of grades of various parameters however did not reveal any significant difference at 6 months. CONCLUSIONS Adjuvant treatment with topical CsA is not superior to standard therapy, in cases of acute SJS.

Abstract
PURPOSE To investigate changes in the ocular surface and subjective symptoms during a three months administration of 3% diquafosol long-acting (DQL) eye drops. STUDY DESIGN Prospective observational study. METHODS DQL eye drops were administered as the sole treatment for all patients, including those in the group where DQL eye drops were newly prescribed (New DQL) and the group who switched from 3% diquafosol (DQS) eye drops (Switched DQL) in this prospective study. Each group underwent assessment of tear meniscus height (TMH), ocular surface disease index (OSDI), fluorescein break-up time (FBUT), fluorescein score, and Schirmer 1 test before DQL administration, at one month, and at three months. Changes in ocular surface scores and subjective symptoms at each time point were analyzed. RESULTS The study included a total of 63 eyes of 63 patients, with a mean age of 60.3 ±14.6 (SD). Among them, 29 patients (20 women) were in the New DQL group, and 34 patients (24 women) were in the Switched DQL group. Both the New DQL and Switched DQL groups showed significant improvements in TMH, OSDI, FBUT, Fluorescein Score, and Schirmer 1 test after three months of DQL eye drop administration. CONCLUSION DQL eye drops have the potential to improve ocular scores and subjective symptoms in patients with DE over a three months period, regardless of whether it is newly initiated or as a switch from DQS eye drops.

Abstract
Background Laser therapy has been proven as an effective technique for managing ophthalmological disorders. To guide future research, we conducted a bibliometric analysis of laser applications in eye diseases from 1990 to 2022, aiming to identify key themes and trends. Methods We retrieved 3027 publications from the Web of Science Core Collection (WoSCC). Bibliometrix was used for science mapping of the literature, while VOSviewer and CiteSpace were applied to visualize co-authorship, co-citation, co-occurrence, and bibliographic coupling networks. Results From a co-citation reference network, we identified 52 distinct clusters. Our analysis uncovered three main research trends. The first trend revolves around the potential evolution of corneal laser surgery techniques, shifting from the treatment of refractive errors to broader applications in biomedical optics. The second trend illustrates the advancement of laser applications in treating a range of disorders, from retinal and ocular surface diseases to glaucoma. The third trend focuses on the innovative uses of established technologies. Conclusion This study offers significant insights into the evolution of laser applications in ophthalmology over the past 30 years, which will undoubtedly assist scientists in directing further research in this promising field.

Clin Ophthalmol 2024; 18:1329-1339. [PMID: 38765455 PMCID: PMC11100494 DOI: 10.2147/opth.s458715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Accepted: 04/28/2024] [Indexed: 05/22/2024] Open
Abstract
Purpose To assess changes in symptoms and ocular surface signs following a bilateral sutureless treatment of dehydrated amniotic membrane (dAM) under a specialised bandage contact lens (sBCL) in patients with moderate-to-severe dry eye disease (DED). Patients and Methods In this prospective pre-post interventional study, 35 patients diagnosed with moderate-to-severe DED, with an Ocular Surface Disease Index (OSDI) score >30 on current treatment, were enrolled. Assessments were conducted at baseline (day -30), after 30 days run-in with no additional treatment (day 0 - control), and 30 days post sBCL+dAM treatment (day 30 - treatment). Intervention involved two successive bilateral 4-5 day sutureless applications of dAM (17mm diameter, with a 6 mm central aperture, Omnigen® VIEW) under an 18mm sBCL (OmniLenz®). Symptomatology and ocular signs were measured using OSDI, Dry Eye Questionnaire-5 (DEQ-5), Symptom Assessment iN Dry Eye (SANDE), and other ocular surface health indicators including non-invasive breakup time, corneal and conjunctival staining, and lid wiper epitheliopathy length and width (LWE). Results While symptomatology remained stable during the 30-day no-treatment run-in, 1-month post-dAM treatment, there was a significant reduction in OSDI scores (from 55.8 to 32.3, p<0.001), DEQ-5 (from 14.6 to 10.0, p<0.001), SANDE frequency (from 65.2 to 43.6, p<0.001), and SANDE severity (from 59.8 to 41.1, p<0.001). Additionally, there was a notable decrease in the width of LWE staining, from grade 2 (50-75% of the lid wiper) to grade 1 (25-50% of the lid wiper) (p=0.011). Conclusion A bilateral 8-10-day treatment duration with dAM applied with sBCL demonstrated a 31 to 42% improvement in symptomatology and a decrease in ocular surface signs of mechanical stress. This innovative bilateral treatment approach offers a promising treatment modality for patients with refractory moderate-to-severe DED.

[PMID: 38703931 DOI: 10.1016/j.ijpharm.2024.124192] [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: 03/08/2024] [Revised: 04/21/2024] [Accepted: 04/30/2024] [Indexed: 05/06/2024]
Abstract
Ocular delivery is the most challenging aspect in the field of pharmaceutical research. The major hurdle for the controlled delivery of drugs to the eye includes the physiological static barriers such as the complex layers of the cornea, sclera and retina which restrict the drug from permeating into the anterior and posterior segments of the eye. Recent years have witnessed inventions in the field of conventional and nanocarrier drug delivery which have shown considerable enhancement in delivering small to large molecules across the eye. The dynamic challenges associated with conventional systems include limited drug contact time and inadequate ocular bioavailability resulting from solution drainage, tear turnover, and dilution or lacrimation. To this end, various bioactive-based nanosized carriers including liposomes, ethosomes, niosomes, dendrimer, nanogel, nanofibers, contact lenses, nanoprobes, selenium nanobells, nanosponge, polymeric micelles, silver nanoparticles, and gold nanoparticles among others have been developed to circumvent the limitations associated with the conventional dosage forms. These nanocarriers have been shown to achieve enhanced drug permeation or retention and prolong drug release in the ocular tissue due to their better tissue adherence. The surface charge and the size of nanocarriers (10-1000 nm) are the important key factors to overcome ocular barriers. Various nanocarriers have been shown to deliver active therapeutic molecules including timolol maleate, ampicillin, natamycin, voriconazole, cyclosporine A, dexamethasone, moxifloxacin, and fluconazole among others for the treatment of anterior and posterior eye diseases. Taken together, in a nutshell, this extensive review provides a comprehensive perspective on the numerous facets of ocular drug delivery with a special focus on bioactive nanocarrier-based approaches, including the difficulties and constraints involved in the fabrication of nanocarriers. This also provides the detailed invention, applications, biodistribution and safety-toxicity of nanocarriers-based therapeutcis for the ophthalmic delivery.

Abstract
INTRODUCTION To assess the efficacy and safety of the combination of microblepharoexfoliation (MBE), intense pulse light (IPL) and meibomian gland expression (MGX) for treatment of meibomian gland dysfunction (MGD). METHODS This was a prospective, parallel-control trial conducted from April 2022 to January 2023. Participants were assigned to receive either three sessions of MBE-IPL-MGX treatment and home-based therapy (treatment group) or home-based therapy alone (control group). Outcome measures were assessed at baseline and after 2-month follow-up. RESULTS Seventy eyes of 70 patients were enrolled. MBE-IPL-MGX treatment achieved better improvements than home-based therapy in ocular surface disease index (OSDI) and symptom assessment in dry eye (SANDE) scores, noninvasive tear film break-up time (NIBUT), lipid layer grade (LLG), loss area meibomian gland (LAMG) and meibomian gland yielding secretion score (MGYSS). The mean differences between the two groups were as follows: OSDI (- 11.23 ± 4.68 points, P < 0.001), SANDE (- 24.63 ± 13.41 points, P < 0.001), NIBUT (1.3 ± 1.57 s, P = 0.033), LLG (0.4 ± 0.04 points, P = 0.003), LAMG (- 2.85 ± 1.69%, P = 0.023) and MGYSS (7.5 ± 2.32 points, P < 0.001). In addition, the increment (Δ) of MGYSS after MBE-IPL-MGX treatment was significantly higher in MGD grades 2 and 3 (all P < 0.001). CONCLUSIONS MBE-IPL-MGX treatment is an effective and well-tolerated procedure that improves dry eye symptoms and signs as well as meibomian gland secretions in patients with MGD. In addition, this treatment is recommended for MGD grades 2 and 3.

Abstract
ABSTRACT Dry eye disease is a common multifactorial condition that may be idiopathic or associated with autoimmune conditions, such as Sjogren syndrome. Commensal microorganisms modify immune responses, so it is relevant to understand how they modify such immune-mediated diseases. Microbiota in the gut regulate inflammation in the eye, and conversely, severe inflammation of the ocular surface results in alteration of gut microbiome. The conjunctiva microbiome can be analyzed using 16S or shotgun metagenomics. The amount of microbial DNA in ocular surface mucosa relative to human DNA is limited compared with the case of the intestinal microbiome. There are challenges in defining, harvesting, processing, and analyzing the microbiome in the ocular surface mucosa. Recent studies have shown that the conjunctiva microbiome depends on age, presence of local and systemic inflammation, and environmental factors. Microbiome-based therapy, such as the use of oral probiotics to manage dry eye disease, has initial promising results. Further longitudinal studies are required to investigate the alteration of the conjunctival microbiome after local therapy and surgery.

Abstract
PURPOSE To determine the visual outcome and postoperative complications of cataract surgery in patients with ocular surface disorders (OSDs). SETTING Tertiary eyecare center in North India. DESIGN Retrospective observational study. METHODS Patients with various OSDs with stabilized ocular surfaces who underwent cataract surgery during this period and had a minimum postoperative follow-up of 6 weeks were included. The primary outcome measures were postoperative corrected distance visual acuity (CDVA) at 6 weeks, best CDVA achieved, and postoperative complications. RESULTS The study included 20 men and 24 women. A total of 55 eyes were evaluated: Stevens-Johnson syndrome (SJS) 35 eyes, ocular cicatricial pemphigoid (OCP) 4 eyes, 8 eyes with dry eye disease (DED), 6 eyes with chemical injury and 2 eyes with vernal keratoconjunctivitis (VKC). The mean duration of OSD was 33.9 ± 52.17 months. The median preoperative CDVA was 2.0 (interquartile range [IQR], 1.45 to 2.0). The median CDVA ever achieved was 0.50 (IQR, 0.18 to 1.45) at 2 months and the median CDVA at 6 weeks was 0.6 (IQR, 0.3 to 1.5). Maximum improvement in CDVA was noted in patients with DED and SJS and the least in OCP. Phacoemulsification was performed in 47.27% eyes with intraoperative complications noted in 9% eyes. Postoperative surface complications occurred in 12 (21.82%) eyes. Other postoperative complications occurred in 9 (16%) eyes. CONCLUSIONS Cataract surgery outcome can be visually rewarding in patients with OSDs provided ocular surface integrity is adequately maintained preoperatively and postoperatively.

Abstract
This study aimed to investigate the efficacy and safety of trigeminal parasympathetic pathway (TPP) stimulation in the treatment of dry eye. A comprehensive search for randomized clinical trials was performed in seven databases (MEDLINE, Embase, CENTRAL, etc.) up to 28 February 2023. After screening the suitable studies, the data were extracted and transformed as necessary. Data synthesis and analysis were performed using Review Manager 5.4, and the risk of bias and quality of evidence were evaluated with the recommended tools. Fourteen studies enrolling 1714 patients with two methods (electrical and chemical) of TPP stimulation were included. Overall findings indicate that TPP stimulation was effective in reducing subjective symptom score (standardized mean difference [SMD], -0.45; 95% confidence interval [CI], -0.63 to -0.28), corneal fluorescence staining (mean difference [MD], -0.78; 95% CI, -1.39 to -0.18), goblet cell area (MD, -32.10; 95% CI, -54.58 to -9.62) and perimeter (MD, -5.90; 95% CI, -10.27 to -1.53), and increasing Schirmer's test score (SMD, 0.98; 95% CI, 0.65 to 1.31) and tear film break-up time (SMD, 0.57; 95% CI, 0.19 to 0.95). Compared to inactive or low-activity stimulation controls, it has a higher incidence of adverse events. Therefore, TPP stimulation may be an effective treatment for dry eye, whether electrical or chemical. Adverse events are relatively mild and tolerable. Due to the high heterogeneity and low level of evidence, the current conclusions require to be further verified.

Abstract
INTRODUCTION To evaluate the short-term efficacy of cyclosporine A (CsA)-0.1% cationic emulsion (CE) in patients with dry eye disease (DED) and mitigation of the inflammatory flares triggered by desiccating stress environments. METHODS A single-center non-randomized clinical trial was performed at a tertiary care setting. Twenty patients with DED treated with CsA 0.1% CE were exposed to a normal controlled environment (NCE) (23 °C, 50% relative humidity) and an adverse controlled environment (ACE) (23 °C, 10% relative humidity, 0.43 m/s localized airflow) during baseline and the 1- and 3-month visits. Patients underwent the following evaluations: conjunctival hyperemia and staining, corneal fluorescein staining (CFS) using the Oxford and Cornea and Contact Lens Research Unit (CCLRU) scale, meibomian gland (MG) secretion quality, Dry Eye Questionnaire-5, Symptom Assessment in Dry Eye (SANDE II), and Change in Dry Eye Symptoms Questionnaire. Multivariate models were adjusted for statistical analysis. RESULTS Nineteen women and one man (mean age, 58.9 ± 12.3 years) completed the study. All symptom questionnaires, CFS, conjunctival hyperemia and staining, and MG secretion quality improved (p ≤ 0.003) with 1 month of treatment; improvements were maintained after 3 months (p ≤ 0.02), except for SANDE II (p ≥ 0.07). The CFS worsening (total CCLRU) after baseline ACE exposure (from 8.6 to 10.1) was higher, although not significant (p = 0.64), compared with 1 month (from 5.4 to 5.8) and 3 months (from 5.0 to 5.9) after treatment. CONCLUSION Topical CsA-0.1% CE improved DED signs and symptoms after 1 month of treatment under controlled environmental conditions. Future studies should confirm the benefit of CsA-0.1% CE in desiccating stress environments. TRIAL REGISTRATION ClinicalTrials.gov identifier, NCT04492878.

Abstract
BACKGROUND To assess the efficacy of curcuminoids (curcumin, demethoxycurcumin, bisdemethoxycurcumin [BDC]) and their analogs (tetrahydrocurcumin [THC], tetrahydrodemethoxycurcumin [THDC], tetrahydrobisdemethoxycurcumin) in reducing inflammatory cytokines and their toxicity to primary human corneal limbal epithelial cells, these cells were cultured and exposed to these compounds. METHODS The PrestoBlue assay assessed cell viability after treatment. Anti-inflammatory effects on hyperosmotic cells were determined using real-time polymerase chain reaction and significance was gauged using one-way analysis of variance and Tukey's tests, considering p-values < 0.05 as significant. RESULTS Curcuminoids and their analogs, at 1, 10, and 100 µM, exhibited no effect on cell viability compared to controls. However, cyclosporin A 1:500 significantly reduced cell viability more than most curcuminoid treatments, except 100 µM curcumin and BDC. All tested curcuminoids and analogs at these concentrations significantly decreased mRNA expression levels of tumor necrosis factor-α, interleukin (IL)-1β, IL-6, IL-17 A, matrix metallopeptidase-9, and intercellular adhesion molecule-1 after 90 mM NaCl stimulation compared to untreated cells. Furthermore, proinflammatory cytokine levels from hyperosmotic cells treated with 1, 10, and 100 µM curcumin, 100 µM BDC, 100 µM THC, 1 and 100 µM THDC mirrored those treated with cyclosporin A 1:500. CONCLUSION The anti-inflammatory efficiency of 1 and 10 µM curcumin, 100 µM THC, 1 and 100 µM THDC was comparable to that of cyclosporin A 1:500 while maintaining cell viability.

Abstract
CLINICAL RELEVANCE This clinical trial was conducted as part of the marketing procedures for a medical device comprising artificial tears containing Artemia salina extract with dinucleotides. These molecules previously demonstrated secretagogue properties by enhancing the production of aqueous, mucinous, and lipidic components of the tears. BACKGROUND After confirming the efficacy of artificial tears containing Artemia salina extract in an animal model, this study proceeded to evaluate their efficacy and safety on dry eye participants. METHODS A randomised controlled clinical trial was performed on 36 dry eye participants (41.6 ± 20.6 years). Half of the participants were treated with saline solution as a placebo for four weeks, while the other half were treated with artificial tears containing Artemia salina, randomly assigned. After a wash-out period of two weeks, the treatments were crossed for another four weeks. Participants were assessed at baseline and after one week, two weeks, and four weeks. Efficacy variables were: eye dryness frequency (primary), eye comfort, visual satisfaction, tear secretion, tear break-up time, corneal staining, conjunctival staining, and conjunctival hyperaemia. Safety variables were: high- and low-contrast visual acuity, intraocular pressure, and eye fundus images analysis. RESULTS Compared with the baseline, the saline solution showed no significant changes in any of the studied variables after four weeks of treatment (p ≥ 0.05). However, the topical instillation of the artificial tears with Artemia salina for four weeks significantly improved eye dryness frequency (p = 0.014) and corneal staining (p = 0.010). No systemic or ocular adverse events were reported during the clinical trial. CONCLUSION The topical instillation of artificial tears containing Artemia salina in mild to moderate dry eye participants for four weeks slightly improved their symptoms related to eye dryness frequency and reduced corneal damage, with no undesirable side effects observed.

Abstract
Dry eye disease (DED) incidence is continuously growing, positioning it to become an emergent health issue over the next few years. Several topical treatments are commonly used to treat DED; however, reports indicate that only a minor proportion of drug bioavailability is achieved by the majority of eye drops available on the market. In this context, enhancing drug ability to overcome ocular barriers and prolonging its residence time on the ocular surface represent a new challenge in the field of ocular carrier systems. Therefore, research has focused on the development of multi-functional nanosystems, such as nanoemulsions, liposomes, dendrimers, hydrogels, and other nanosized carriers. These systems are designed to improve topical drug bioavailability and efficacy and, at the same time, require fewer daily administrations, with potentially reduced side effects. This review summarizes the different nanotechnologies developed, their role in DED, and the nanotechnology-based eyedrops currently approved for DED treatment.

Abstract
Artificial intelligence (AI) has emerged as a transformative force with great potential in various fields, including healthcare. In recent years, AI has garnered significant attention due to its potential to revolutionise ophthalmology, leading to advancements in patient care such as disease detection, diagnosis, treatment and monitoring of disease progression. This study presents a comprehensive analysis of the research trends and collaborative networks at the intersection of AI and ophthalmology. In this study, we conducted an extensive search of the Web of Science Core Collection to identify articles related to 'artificial intelligence' in ophthalmology published from 1968 to 2023. We performed co-occurrence keywords and co-authorship network analyses using VOSviewer software to explore the relationships between keywords and country collaboration. We found a remarkable surge in articles applying AI in ophthalmology after 2017, marking a turning point in the integration of AI within the medical field. The primary application of AI shifted towards the diagnosis of ocular disease, which was particularly evident through keywords such as glaucoma, diabetic retinopathy and age-related macular degeneration. Analysis of the collaboration networks of countries revealed a global expansion of ophthalmology-related AI research. This study provides valuable insights into the evolving landscape of AI integration in ophthalmology, indicating its growing potential for enhancing disease detection, diagnosis, treatment planning and monitoring of disease progression. In order to translate AI technologies into clinical practice effectively, it is imperative to comprehend the evolving research trends and advancements at the intersection of AI and ophthalmology.

Are artificial intelligence chatbots a reliable source of information about contact lenses? Cont Lens Anterior Eye 2024; 47:102130. [PMID: 38443210 DOI: 10.1016/j.clae.2024.102130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 02/12/2024] [Accepted: 02/20/2024] [Indexed: 03/07/2024]
Abstract
INTRODUCTION Artificial Intelligence (AI) chatbots are able to explain complex concepts using plain language. The aim of this study was to assess the accuracy of three AI chatbots answering common questions related to contact lens (CL) wear. METHODS Three open access AI chatbots were compared: Perplexity, Open Assistant and ChatGPT 3.5. Ten general CL questions were asked to all AI chatbots on the same day in two different countries, with the questions asked in Spanish from Spain and in English from the U.K. Two independent optometrists with experience working in each country assessed the accuracy of the answers provided. Also, the AI chatbots' responses were assessed if their outputs showed any bias towards (or against) any eye care professional (ECP). RESULTS The answers obtained by the same AI chatbots were different in Spain and the U.K. Also, statistically significant differences were found between the AI chatbots for accuracy. In the U.K., ChatGPT 3.5 was the most and Open Assistant least accurate (p < 0.01). In Spain, Perplexity and ChatGPT were statistically more accurate than Open Assistant (p < 0.01). All the AI chatbots presented bias, except ChatGPT 3.5 in Spain. CONCLUSIONS AI chatbots do not always consider local CL legislation, and their accuracy seems to be dependent on the language used to interact with them. Hence, at this time, although some AI chatbots might be a good source of information for general CL related questions, they cannot replace an ECP.

Klin Monbl Augenheilkd 2024; 241:421-425. [PMID: 38653304 DOI: 10.1055/a-2243-5519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 04/25/2024]
Abstract
BACKGROUND Ocular surface disorder after ocular radiation therapy, even though commonly reported, is often overlooked. Any delay in diagnosis may lead to complications that threaten vision. The presented case highlights the clinical outcome of a severe post-radiation disorder of the ocular surface, the importance of intensive therapy, and the limitations of further surgical interventions. CASE PRESENTATION A 34-year-old woman was referred for a second opinion due to a years-long history of pain and redness in her right eye (OD) after proton beam therapy for recurrent iris melanoma. The patient then developed post-radiation retinopathy with macula edema, secondary glaucoma, cataract, as well as a severe ocular surface disorder with corneal decompensation and band keratopathy. Several surgical treatments have been attempted, including phacoemulsification with IOL implantation and trabeculectomy with mitomycin C. Due to refractory glaucoma, Baerveldt glaucoma drainage was then necessary. Given the worsening clinical presentation of post-radiation ocular surface disorder with progressing band keratopathy, the possibility of penetrating keratoplasty (PKP) was discussed. CONCLUSION The continuous worsening of clinical symptoms of the disorder of the ocular surface after proton beam radiotherapy can be the result of a post-radiation syndrome. Gradual expansion of ischemia, vasculitis, and inflammatory mediators compresses the retinal tissue, leading to recurrent macular edema as well as to secondary glaucoma and corneal decompensation. Band keratopathy is occasionally noted and seems to result from severe post-radiation disorder of the ocular surface. However, PKP would typically be indicated in cases of corneal perforation, uncontrolled infectious keratitis, or for improving vision in the presence of corneal opacification, none of which applied to our patient. Furthermore, post-radiation keratopathy implies compromised corneal stromal lymphogenesis and angiogenesis, both of which are now considered essential conditions for allograft rejection. Moreover, a previously performed Baerveldt glaucoma drainage surgery can affect the survival rate of the endothelial cells of the recipient cornea. Therefore, a penetrating or endothelial keratoplasty should be viewed as a high-risk procedure. In this instance, the rigorous treatment of the severe ocular surface disorder was crucial. We managed our patient's complex situation by following the latest guidelines set by the Tear Film & Ocular Surface Society and aimed to alleviate the symptoms as effectively as possible. In conclusion, careful decision-making regarding surgical treatment options should be considered, taking into account the complexities and potential risks involved.

Abstract
Perfluorohexyloctane ophthalmic solution (Miebo®) is a single-entity, water-, steroid- and preservative-free, first-in-class semifluorinated alkane that is approved in the USA for the treatment of the signs and symptoms of dry eye disease (DED). DED is often linked with meibomian gland dysfunction (MGD), which causes an excessive evaporation of tears. Perfluorohexyloctane ophthalmic solution stabilizes the lipid layer of the tear film and inhibits tear evaporation by forming a monolayer at the air-liquid interface. In the phase III GOBI and MOJAVE trials in adults with DED associated with MGD, one drop of perfluorohexyloctane ophthalmic solution instilled in each eye four times daily over 8 weeks resulted in statistically significant and clinically meaningful improvements in the signs and symptoms of DED compared with hypotonic saline (0.6%). The agent was generally well tolerated, with most ocular adverse events being mild or moderate in severity. The efficacy and tolerability of perfluorohexyloctane ophthalmic solution was sustained for up to 52 weeks in an extension study (KALAHARI). As the first and currently the only prescription treatment approved in the USA directly addressing the pathophysiology of excessive tear evaporation, perfluorohexyloctane ophthalmic solution is a valuable emerging option for the management of DED.

Abstract
Climate change is a threat to human health and wellbeing across the world. In recent years, there has been a surge in awareness of this crisis, leading to many countries and organisations setting "net-zero" targets. This entails minimising carbon emissions and neutralising remaining emissions by removing carbon from the atmosphere. At the 2022 United Nations Climate Change Conference (COP27), commitments to transition away from fossil fuels and augment climate targets were underwhelming. It is therefore imperative for public and private sector organisations to demonstrate successful implementation of net-zero and set a precedent for the global political consensus. As a top 10 world employer, the United Kingdom National Health Service (NHS) has pledged to reach net-zero by 2045. The NHS has already taken positive steps forward, but its scale and complexity as a health system means stakeholders in each of its services must highlight the specifications for further progress. Dry eye disease is a chronic illness with an estimated global prevalence of 29.5% and an environmentally damaging care pathway. Moreover, environmental damage is a known aggravator of dry eye disease. Worldwide management of this illness generates copious amounts of non-recyclable waste, utilises inefficient supply chains and involves recurrent follow-up appointments and prescriptions. By mapping the dry eye disease care pathway to environmental impact, in this review we will highlight seven key areas in which reduced emissions and pollution could be targeted. Examining these approaches for improved environmental sustainability is critical in driving the transformation needed to preserve our health and wellbeing.

Abstract
PURPOSE To evaluate the effects of topical 0.05% cyclosporine A on Ocular Surface Disease Index (OSDI) score and ocular surface parameters after small incision lenticule extraction (SMILE) for myopia. METHODS In this study, 151 patients who underwent SMILE were randomized into the control group (71 eyes) and the 0.05% cyclosporine A group (80 eyes). Both groups received standard treatment during the 1 month after SMILE. Over the next 3 months, The control group continued standard therapy (0.3% sodium hyaluronate) and the 0.05% cyclosporine A group received additional 0.05% cyclosporine A. OSDI total and subscale scores, non-invasive tear break-up time (NIBUT), tear lipid layer thickness (LLT), and tear meniscus height (TMH) were assessed preoperatively and postoperatively. RESULTS Compared to baseline, the OSDI scores significantly increased in both groups (P < .001). The 0.05% cyclosporine A group exhibited lower OSDI total scores after administering 0.05% cyclosporine A versus the control group (P = .026). At 1 month of follow-up, NIBUT, LLT, and TMH values significantly decreased in both groups compared to baseline (P < .05). The 0.05% cyclosporine A group exhibited higher NIBUT, LLT, and TMH versus the control group, returning to preoperative values after 2 months. Overall, the OSDI total score and NIBUT values during follow-up were not significantly different between the two groups; however, the LLT and TMH values were significantly different between the two groups (P < .001 and .041, respectively) by repeated measures analysis of variance. CONCLUSIONS Topical 0.05% cyclosporine A was effective in relieving subjective dry eye symptoms and maintaining ocular surface stability in the early postoperative period of SMILE.

Varenicline solution nasal spray for dry eye disease in Chinese patients: a randomized phase 3 trial. THE LANCET REGIONAL HEALTH. WESTERN PACIFIC 2024; 45:101032. [PMID: 38440130 PMCID: PMC10909742 DOI: 10.1016/j.lanwpc.2024.101032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 01/18/2024] [Accepted: 01/29/2024] [Indexed: 03/06/2024]
Abstract
Background Dry eye disease has a high prevalence and exerts a significant negative effect on quality of life. In China, there are currently no available nasal sprays to promote natural tear production in patients with dry eye disease. We therefore evaluated the efficacy and safety of OC-01 (varenicline solution) nasal spray versus vehicle in Chinese patients with dry eye disease. Methods This was a randomized, multicenter, double-masked, vehicle-controlled, phase 3 clinical trial conducted at ophthalmology departments in 20 hospitals across China (NCT05378945). Eligible patients had a diagnosis of dry eye disease based on patient symptoms, Eye Dryness Score (EDS), Schirmer's Test (with topical anesthesia) Score (STS), and corneal fluorescein staining (CFS) score. Participants were randomly assigned 1:1 using an Interactive Web Response System (IWRS) to receive OC-01 0.6 mg/mL twice daily (BID) or vehicle nasal spray. Participants, investigators, and sponsor were all masked to treatment assignment. The primary endpoint was the percentage of subjects in the intention-to-treat population achieving ≥10 mm improvement in STS from baseline at week 4. Findings In total, 340 patients were randomized from 21 July 2022 to 04 April 2023, 78.8% were female. Patients in the OC-01 group (n = 176) had significantly higher achievement of ≥10 mm improvement in STS (35.8% [n = 63] versus 17.7% [n = 29], stratified odds ratio: 2.67, 95% CI: 1.570-4.533, p = 0.0002) and a significantly greater increase from baseline STS (least-squares mean difference [SE]: 3.87 [0.794], p < 0.0001) at week 4 versus the vehicle group (n = 164). In addition, OC-01 led to a numerically greater reduction in mean EDS from baseline at week 4 compared to the vehicle group (LS mean [SE] difference: -1.3 [2.20]; 95% CI: -5.64 to 2.99, p = 0.5467). The most common adverse event was mild, transient sneezing (78% of OC-01 administrations). No serious adverse events related to nasal administration occurred. Interpretation OC-01 (varenicline solution) nasal spray BID has clinically meaningful efficacy for reducing the signs (as measured by STS) and may improve the symptoms (as measured by EDS) of dry eye disease, with an excellent safety and tolerability profile, in the Chinese population.

Efficacy of meibomian gland expression combined with Home-Based therapy in the management of dry eye Disease: A systematic review and Meta-Analysis. Cont Lens Anterior Eye 2024; 47:102107. [PMID: 38135593 DOI: 10.1016/j.clae.2023.102107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 12/05/2023] [Accepted: 12/13/2023] [Indexed: 12/24/2023]
Abstract
PURPOSE To compare the effectiveness of meibomian gland expression (MGX) combined with home-based therapy versus home-based therapy alone for the treatment of dry eye disease (DED) caused by meibomian gland dysfunction (MGD). METHODS A systematic review of randomized controlled studies (RCTs), reporting the effects of MGX combined with home-based therapy in 2 databases, PubMed and Web of Science, was performed according to the PRISMA statement. The search period was until August 20, 2023. According to the heterogeneity, a random or fixed effects model was performed in the meta-analysis. The standardized mean difference (SMD) was calculated to analyze dry eye symptoms (DES) score, tear film break-up time (TBUT), total corneal fluorescein staining (tCFS) and meibomian glands expressibility (MGE). All analyses were performed by RevMan Web, version 5.7. The Cochrane risk of bias tool was used to analyze the quality of the studies selected. RESULTS Two RCTs with a total of 99 patients were included. The studies reported that MGX combined with home-based therapy improves DES score, TBUT, tCFS and MGE compared to the home-based therapy. However, the meta-analysis indicated that MGX combined with home-based therapy only seems to be beneficial in reducing DES score (SMD -0.49; 95 % CI: -0.89 to -0.08; P = 0.02; I2 = 0 %). In addition, although TBUT, tCFS and MGE reported a slight trend in favor of MGX combined with home-based therapy, it was non-significant. CONCLUSIONS While MGX combined with home-based therapy seem to show some evidence of alleviating dry eye symptoms, there is insufficient evidence to conclude the effects of this treatment definitively particularly in improving dry eye signs caused by MGD, such as TBUT, tCFS and MGE. Therefore, further RCTs are needed to elucidate these results.

Abstract
New Korean guidelines for the diagnosis and management of dry eye disease were developed based on literature reviews by the Korean Dry Eye Guideline Establishment Committee, a previous dry eye guideline by Korean Corneal Disease Study Group, a survey of Korean Dry Eye Society (KDES) members, and KDES consensus meetings. The new definition of dry eye was also proposed by KDES regular members. The new definition by the regular members of the KDES is as follows: "Dry eye is a disease of the ocular surface characterized by tear film abnormalities and ocular symptoms." The combination of ocular symptoms and an unstable tear film (tear breakup time <7 seconds) was considered as essential components for the diagnosis of dry eye. Schirmer test and ocular surface staining were considered adjunctive diagnostic criteria. The treatment guidelines consisted of a simplified stepwise approach according to aqueous deficiency dominant, evaporation dominant, and altered tear distribution subtypes. New Korean guidelines can be used as a simple, valid, and accessible tool for the diagnosis and management of dry eye disease in clinical practice.

Abstract
Dry eye disease (DED) is a multifactorial condition affecting the ocular surface. It is characterized by loss of tear film homeostasis and accompanied by ocular symptoms that may potentially result in damage to the ocular surface and even vision loss. Unmodifiable risk factors for DED mainly include aging, hormonal changes, and lifestyle issues such as reduced sleep duration, increased screen exposure, smoking, and ethanol consumption. As its prevalence continues to rise, DED has garnered considerable attention, prompting the exploration of potential new therapeutic targets. Recent studies have found that when the production of ROS exceeds the capacity of the antioxidant defense system on the ocular surface, oxidative stress ensues, leading to cellular apoptosis and further oxidative damage. These events can exacerbate inflammation and cellular stress responses, further increasing ROS levels and promoting a vicious cycle of oxidative stress in DED. Therefore, given the central role of reactive oxygen species in the vicious cycle of inflammation in DED, strategies involving antioxidants have emerged as a novel approach for its treatment. This review aims to enhance our understanding of the intricate relationship between oxidative stress and DED, thereby providing directions to explore innovative therapeutic approaches for this complex ocular disorder.

Graefes Arch Clin Exp Ophthalmol 2024:10.1007/s00417-024-06431-y. [PMID: 38520515 DOI: 10.1007/s00417-024-06431-y] [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: 11/15/2023] [Revised: 02/20/2024] [Accepted: 02/27/2024] [Indexed: 03/25/2024] Open
Abstract
PURPOSE The healthcare system is responsible for around 5% of CO2 emissions globally and in Germany. So far, there are no data on the amount of waste from dry eye disease (DED) therapy in ophthalmology. The aim of this project was to evaluate the amount and type of waste from single- and multi-dose units (SDU/MDU) generated by eyedrops used to treat DED in Germany. METHODS The net waste weight (outer/inner packaging, instruction leaflet, empty container) from factory-sealed products was determined using a precision scale. Based on prescription data from PharMaAnalyst, a database of medical prescriptions from over 70 million patients in Germany, the total annual waste volume for 2016-2021 and the net weight of a 30-day treatment were calculated. RESULTS The total annual waste volume increased significantly (p < 0.0001) from 7.13 tons in 2016 to 20.64 tons in 2021. A 30-day treatment with MDUs (without/with filter) results in a significantly lower mean waste volume (paper: SDU 24.3 ± 18.7 g; MDU 4.8 ± 1.7 g/8.8 g ± 1.7 g; SDU/MDU p = 0.0003, with filter p = 0.0034; plastic: SDU 35.0 ± 4.0, MDU 6.6 ± 0.7 g/ 15.1 g ± 5.8 g, SDU/MDU p < 0.0001, with filter p < 0.0001). CONCLUSION Prescription-based treatment of DED in Germany causes an increasing and substantial waste volume. The use of SDUs is considerably more resource-intensive than MDUs. Due to the large and rising number of patients suffering from DED improvements in packaging could considerably reduce the CO2 footprint of DED treatment.

Abstract
In the Middle East and Northern Africa (MENA), dry eye disease (DED) is often misdiagnosed or overlooked. This review summarizes a series of conversations with ophthalmologists in the region around a variety of climatic, lifestyle, and iatrogenic factors that contribute to specific features of DED in the MENA region. These considerations are further classified by patient lifestyle and surgical choices. All statements are based on discussions and formal voting to achieve consensus over three meetings. Overall, a deeper understanding of the disease characteristics of DED specific to MENA can better guide local eyecare practitioners on appropriate management and follow-up care. Additionally, population-based studies and patient and physician education on ocular surface diseases, together with the use of culturally appropriate and language-specific questionnaires can help ease the public health burden of DED in this region.

Abstract
Traditional Chinese Medicine has a long history in ophthalmology in China. Over 250 kinds of Traditional Chinese Medicine have been recorded in ancient books for the management of eye diseases, which may provide an alternative or supplement to current ocular therapies. However, the core holistic philosophy of Traditional Chinese Medicine that makes it attractive can also hinder its understanding from a scientific perspective - in particular, determining true cause and effect. This review focused on how Traditional Chinese Medicine could be applied to two prevalent ocular diseases, glaucoma, and cataract. The literature on preclinical and clinical studies in both English and Chinese on the use of Traditional Chinese Medicine to treat these two diseases was reviewed. The pharmacological effects, safety profile, and drug-herb interaction of selected herbal formulas were also investigated. Finally, key considerations for conducting future Traditional Chinese Medicine studies are discussed.

Abstract
PURPOSE OF REVIEW The purpose of this article is to review the available strategies to successfully identify and manage ocular surface disease (OSD) pre, intra and post-cataract surgery. RECENT FINDINGS Cataract surgery and OSD have an intricate relationship: the surgical procedure can induce or exaggerate OSD symptoms, while OSD can negatively impact surgical refractive outcomes and increase the rate of postoperative complications. SUMMARY Improving the health and stability ocular surface is the key to enhance post cataract surgery refractive outcomes and avoid complications. This is pivotal for patients affected by severe OSD, but is also important for patients with minimal signs or symptoms. A correct diagnosis and a stepwise approach are the keys to improve the quality of life of such patients.

Abstract
Physiological wound healing of the cornea is a complex process and involves numerous multifactorial tissue processes. A proper wound healing, especially without the formation of light-scattering scars, is essential to preserve the integrity and function of the cornea. Misdirected wound healing is of vast clinical relevance as it can lead to corneal fibrosis and the loss of optical transparency with subsequent reduction of visual acuity, up to blindness. In addition to the understanding of the pathophysiological mechanisms, the knowledge of therapeutic concepts and options for treating corneal wound healing disorders and fibrosis is essential to counteract a permanent damage of the cornea as early as possible. Nowadays, various pharmacological and surgical options are available for treatment. The decision, appropriate selection and indication for the optimal treatment depend primarily on the genesis and clinical appearance of the corneal wound, fibrosis or scar. The treatment of wound healing disorders ranges from the use of topical therapy and supportive measures up to tissue replacement procedures. As long as the mechanical stability of the cornea is intact and wound healing processes are still ongoing, a pharmacological modulation is reasonable, which is discussed in this article.

Abstract
The amniotic membrane is a single epithelial layer of the placenta. It has anti-inflammatory, anti-scarring, anti-angiogenic and possibly bactericidal properties. The basement membrane of the amniotic membrane acts as a substrate to encourage healing and re-epithelialisation. It has been used in many ocular surface diseases including persistent epithelial defects (corneal or conjunctival), chemical or thermal burns, limbal stem cell deficiency, cicatrising conjunctivitis, ocular graft versus host disease, microbial keratitis, corneal perforation, bullous keratopathy, dry eye disease, corneal haze following refractive surgery and cross-linking, band keratopathy, ocular surface neoplasia, pterygium surgery, and ligneous conjunctivitis. This review provides an up-to-date overview of amniotic membrane transplantation including the structural and biological properties, preparation and application, clinical indications, and commercially available products.

Abstract
Purpose To establish a robust and objective method to evaluate (SPK) superficial punctate keratopathy in a murine dry eye model by developing a reliable photographic system. Design Experimental study. Subjects A murine dry eye model was generated by exorbital lacrimal gland excision. Sham-operated mice were used as healthy controls. For the sham operation, an incision was made without touching the gland. Methods A photographic system was constructed, consisting of an LED lamp and a digital camera fitted with a zoom lens and sharp cut filter. SPK was detected by applying fluorescein solution. To validate the system, SPK was compared between dry eye mice and healthy control mice, and diquafosol (DIQUAS ophthalmic solution 3%; Santen Pharmaceutical Co., Ltd.) or cyclosporine (PAPILOCK Mini ophthalmic solution 0.1%; Santen Pharmaceutical Co., Ltd.) was used to dry eye mice. Main Outcome Measures SPK was evaluated using the parameters of fluorescence score and fluorescein-stained area. Results The photographs clearly indicated SPK in dry eye mice. A fluorescence score of 0 to 9 could be easily assessed, and the fluorescein-stained area was quantifiable. The fluorescein-stained area correlated with fluorescence score (correlation coefficient: 0.98), with good interobserver reliability (intraclass correlation coefficient: 0.999). The fluorescein-stained area increased significantly in dry eye mice compared with that of healthy controls (P < 0.0001). Both types of therapeutic eye drops decreased the fluorescein-stained area relative to saline-treated mice (P < 0.05 in diquafosol vs. saline; P < 0.01 in cyclosporine vs. saline). Conclusions This newly developed system is a robust alternative for quantitative evaluation of SPK in a murine dry eye model.

Abstract
Purpose To compare the effect of treatment with preservative-free dexamethasone, NSAIDs and trehalose/hyaluronic acid eye drops with the preservative benzalkonium chloride containing dexamethasone and NSAIDs after cataract surgery in dry versus non-dry eyes. Patients and Methods In this prospective randomized intervention study, dry eye tests were performed before and 6 weeks after cataract surgery. Patients were considered as having dry eye, SDE (sign of dry eye), if at least one of the following dry eye tests were abnormal; corneal fluorescein staining (CFS), non-invasive keratograph breakup time (NIKBUT) or tear osmolarity. Patients with SDE were randomly assigned to one of two groups. Group 1 patients were treated with dexamethasone and bromfenac eye drops with the preservative benzalkonium chloride (BAC). Group 2 patients were treated with preservative-free dexamethasone and preservative-free diclofenac, as well as a preservative-free lubricant with trehalose and hyaluronic acid both before and after surgery. Patients with normal tear film status acted as the control group (group 3) and received same treatment as group 1. Results A total of 215 patients were enrolled six weeks after surgery, the number of patients with SDE decreased significantly in groups 1 and 2 (p <0.001). Subjective symptoms and objective measures including osmolarity, NIKBUT, CFS, and tear film thickness (TFT) improved after surgery, tear production remained unchanged, while corneal sensitivity and meibomian gland dysfunction (MGD) parameters worsened. In the control group with normal tear-film status, SDE increased significantly after the surgery (p <0.001). There were no statistically significant differences in tear film parameters between the three groups after surgery. Conclusion After cataract surgery, patients with mild to moderate dry eyes may experience improved tear film status and reduced symptoms. However, we found no additional beneficial effect on dry eye parameters with treatment with preservative-free dexamethasone, NSAIDs, and lubricants compared to preservative-containing eye drops.

Abstract
PURPOSE The purpose of this study was to evaluate the progression of dry eye disease (DED) symptoms and signs over 2 years through a secondary analysis of data collected from the Dry Eye Assessment and Management study. METHODS Participants who were assigned to omega-3 fatty acid in the first year were rerandomized in the second year to either continue with omega-3 fatty acid or switch to placebo. At baseline, 3, 6, 12, 18, and 24 months, DED symptoms were evaluated by using the Ocular Surface Disease Index and the Brief Ocular Discomfort Index (BODI). DED signs were assessed using conjunctival staining, corneal staining, tear break-up time, Schirmer testing, and keratography measures. Medication usage was documented at each visit. Because the treatment and placebo groups displayed no statistical differences in both signs and symptoms, data from the 43 participants were combined to assess longitudinal changes in symptoms and signs. RESULTS At 3 months after omega-3 fatty acid treatment, there were significant improvements from baseline in Ocular Surface Disease Index and Brief Ocular Discomfort Index scores (all P ≤ 0.002) and less use of artificial tears or gel (P = 0.02), but between 3 and 24 months, no significant changes in symptoms and treatments were observed (P ≥ 0.06). Except for a significant improvement in conjunctival staining score over 2 years (P = 0.001), there were no significant sign changes in corneal staining (P = 0.32), tear break-up time (P = 0.43), Schirmer test (P = 0.09), and additional measures (all P ≥ 0.07). CONCLUSIONS We did not observe a progression of DED signs or symptoms over a 2-year period, except for a probable placebo response in symptoms in the first 3 months and an improvement in conjunctival staining score.

Abstract
PURPOSE This study aims to evaluate the ocular surface characteristics in children diagnosed with uveitis and explore the association between uveitis and dry eye disease (DED). METHODS We included 84 children, 42 with uveitis and 42 healthy children. We performed the OSDI questionnaire and several ocular surface tests, including osmolarity, NITBUT, Schirmer test, and vital staining. We used Fisher's exact test and Mann-Whitney to compare variables and a binomial logistic regression to determine the factors associated with DED. RESULTS The difference in the prevalence of DED between uveitis (54.8%) and healthy (31%) groups was statistically significant (p < 0.05). Most patients with uveitis had mixed DED, and none of the healthy subjects had a severe form of the disease. There were no statistically significant differences in most of the tear film tests. However, all parameters tended to worsen in the uveitis group, and lipid layer thickness was thinner (p < 0.036). The uveitis group exhibited significantly more symptoms (p < 0.05). In the multivariate logistic regression, uveitis was associated with an odds ratio (OR) of 3.0 (95% CI: 1.07-8.42, p < 0.05) for DED. CONCLUSIONS Our findings demonstrate a significantly higher prevalence of DED in children with uveitis compared to their healthy counterparts. Furthermore, our analysis indicates that the risk of DED in pediatric patients with uveitis is threefold higher than in healthy children. Therefore, it is crucial for clinicians to vigilantly monitor the development of DED in pediatric patients with uveitis and consider the implementation of preventive treatments.

Abstract
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.

Abstract
INTRODUCTION Dry eye disorder (DED) is a growing global issue linked to excessive digital screen time. Chinese eye exercise of acupoint (CEA), a set of self-massages on shared Chinese acupuncture (CA), has been used to reduce visual-related ocular symptoms and possibly as an alternative treatment for DED. This study aimed to assess the efficacy and safety of CEA. METHODS A single-blind randomized controlled trial was conducted at Thammasat University Hospital in Thailand, recruiting 56 participants aged 20-60 years, equally divided into two groups: the treatment group with CEA and the control group with standard lid hygiene treatment (STD). The intervention program lasted 12 weeks. MAIN OUTCOME MEASURES Ocular Surface Disease Index (OSDI), tear break-up time (TBUT), Schirmer-I test (SIT), corneal surface staining (CSS), and self-recorded forms for safety and adverse effects were measured at baseline, week 4, and week 12. An independent sample t test, paired t test, and repeated measures (ANOVA) were used to compare results between both groups, study visits, and primary and secondary outcome measurements, respectively. The p values <0.05 were considered statistically significant. RESULTS The characteristics were not statistically different between both groups at the baseline. The mean OSDI scores were significantly reduced in both groups at week 4 and week 12 compared to baseline (p value <0.05). Additionally, both CEA and STD showed significant improvement in TBUT and SIT (p value <0.05). CSS was significantly improved only in the CEA groups (p value <0.05). No significant differences were observed between the study groups, except for SIT at week 12 (p value <0.05). For the safety, there were no adverse side effects in either group. CONCLUSION CEA seemed to be as effective as STD in improving the OSDI, TBUT, and SIT of DED without causing any side effects. Einleitung Das Trockene Auge (Dry eye disorder, DED) ist weltweit ein zunehmendes Problem, das mit übermässiger Bildschirmarbeit zusammenhängt. Die chinesische Augenübung der Akupunkturpunkte (Chinese eye exercise of acupoint, CEA), eine Reihe von Selbstmassagen an gemeinsamen CA-Akupunkturpunkten, wird zur Linderung visusbezogener Augensymptome und als mögliche alternative Behandlung für DED eingesetzt. Mit dieser Studie sollte die Wirksamkeit und Sicherheit von CEA bewertet werden. Methoden Am Thammasat-Universitätsklinikum in Thailand wurde eine einfach verblindete, randomisierte, kontrollierte Studie mit 56 Teilnehmern im Alter von 20 bis 60 Jahren durchgeführt, die zu gleichen Teilen zwei Gruppen zugewiesen wurden: die Behandlungsgruppe mit CEA und die Kontrollgruppe, die die Standard-Lidhygienebehandlung erhielt (STD). Das Interventionsprogramm dauerte 12 Wochen. Die Haupt-Zielkriterien, der Ocular Surface Disease Index (OSDI), die Tränenfilmaufreisszeit (tear break-up time, TBUT), der Schirmer-I-Test (SIT), das Corneal Surface Staining (CSS) und Selbstauskunftsformulare zur Sicherheit und zu unerwünschten Wirkungen wurden zu Beginn der Behandlung, in Woche 4 und in Woche 12 ermittelt. Für den Vergleich der Ergebnisse zwischen den beiden Gruppen, den Studienvisiten bzw. den primären und sekundären Zielkriterien wurden ein t Test für unabhängige Stichproben, ein t Test für paarige Stichproben und eine ANOVA mit Messwiederholungen verwendet. p-Werte <0,05 galten als statistisch signifikant. Ergebnisse Hinsichtlich der Merkmale bestand zwischen den beiden Gruppen kein statistischer Unterschied bei Studienbeginn. In beiden Gruppen fielen die mittleren OSDI-Scores in Woche 4 und Woche 12 im Vergleich zum Ausgangswert signifikant geringer aus ( p-Wert <0,05). Darüber hinaus zeigten sowohl die CEA- als auch die STD-Gruppe eine signifikante Verbesserung der TBUT- und SIT-Werte ( p-Wert <0,05). Das CSS verbesserte sich nur in der CEA-Gruppe signifikant ( p-Wert <0,05). Zwischen den Studiengruppen waren keine signifikanten Unterschiede zu beobachten, ausser beim SIT in Woche 12 ( p-Wert <0,05). Was die Sicherheit betrifft, so traten in beiden Gruppen keine unerwünschten Nebenwirkungen auf. Schlussfolgerung Die CEA schien die OSDI-, TBUT- und SIT-Werte bei DED ebenso wirksam zu verbessern wie die Standardbehandlung, ohne Nebenwirkungen zu verursachen.

Abstract
Demodex blepharitis does not have agreed standardized guidelines. The aim of this study was to classify signs and symptoms and to develop appropriate management strategies for Demodex blepharitis from a consensus of expert advice. METHODS A total of 11 anterior segment experts (ophthalmologists, optometrists and a contact lens optician) working in the United Kingdom participated in a modified 2-round Delphi panel. A mixed-methods approach was adopted and a survey questionnaire for round 1 was formulated, constructed from information in the available literature. Based on panel responses from round 1, feedback was provided and a round 2 questionnaire was formulated. More than two-thirds majority (72%) was used for consensus building. RESULTS Based on the clinical presentation of signs and symptoms along with associated conditions and risk factors, a diagnostic algorithm was proposed for the clinical investigation of Demodex blepharitis. A treatment algorithm was also proposed with first-line and second-line treatment recommendations for Demodex blepharitis. CONCLUSION The recommendation from this study provides the first effort in formulating clinical diagnostic algorithm and management guidelines for Demodex blepharitis. The guidelines include appropriate magnification on the slit lamp, associated signs, symptoms, risk factors and suggested management options. These guidelines can be used in a routine eyecare setting to encourage eyecare practitioners in tailoring the investigation and management of Demodex blepharitis.

Abstract
PURPOSE To comprehensively review the efficacy and safety of OC-01 varenicline nasal spray versus vehicle nasal spray (VNS) in the treatment in dry eye disease (DED). METHODS A systematic review that included full-length randomized controlled studies (RCTs), as well as post hoc analyses of RCTs reporting new findings on OC-01 VNS treatment in three databases, PubMed, Scopus and Web of Science, was performed according to the PRISMA statement. The search period included studies published between December 2021 and September 2023. The Cochrane risk of bias tool was used to analyze the quality of the studies selected. RESULTS A total of 8 studies were included in this systematic review. OC-01 VNS treatment achieved higher improvement than vehicle in all reported variables. The mean differences between both groups were in favor of OC-01 VNS treatment and were as follow: eye dryness score base on a visual analogue scale (EDS-VAS) of -7.5 ± 2.2 points [-11.6 to -5.6], Schirmer test (ST) with anesthesia of 6.6 ± 2.3 mm [4.9 to 11.8] and total corneal fluorescein staining (tCFS) of -1.2 ± 0.01 points [-1.2 to -1.1]. Similar improvements were reported with OC-01 VNS 0.03 mg and 0.06 mg. Adverse events (AEs) were 15.5 ± 19.4 % [-13 to 80.5] higher in the OC-01 VNS group with an overall adherence > 93 %. CONCLUSIONS OC-01 VNS improves dry eye symptoms and signs with a satisfactory tolerability. Therefore, OC-01 VNS seems to be a safe and effective treatment that could be recommended in patients with DED. This new treatment could be particularly useful in those patients who have difficulties with the administration of traditional topical therapies.

Abstract
INTRODUCTION To evaluate the efficacy and safety of Quantum Molecular Resonance (QMR) treatment in patients with severe dry eye disease (DED), as well as its effects on aqueous-deficient (ADDE), evaporative (EDE), and mixed (MDE) dry eye. METHODS In this prospective, interventional study, 81 patients were randomly allocated to received four treatment sessions of QMR at 1-week intervals (Rexon-Eye®, Resono Ophthalmic, Trieste, Italy) (QRM group) or tear substitute four times daily, containing 0.15% sodium hyaluronate and 3% trehalose (Thealoz Duo®, Thea Pharma, France) (SH-TH group). Outcome measures included ocular surface disease index (OSDI) questionnaire, tear meniscus height (TMH), tear breakup time (TBUT), non-invasive breakup time (NIBUT), corneal fluorescein staining (CFS), lipid layer thickness (LLT), tear film osmolarity (OSM), and meibomian gland dysfunction (MGD) grade, which were assessed at baseline and 1-month and 3-month follow-up. RESULTS The QMR group achieved better improvements than the SH-TH group in OSDI and SANDE questionnaires, NIBUT, LLT, and CFS. The mean differences between the groups were as follows: OSDI (- 12.4 ± 0.25 points, P = 0.01), SANDE (10.6 ± 1.7 points, P = 0.01), NIBUT (2 ± 0.25 s, P = 0.01), LLT (18.7 ± 0.7 nm, P = 0.01), and CFS (1.2 ± 0.1 points, P = 0.02). In subgroups analysis, QMR treatment demonstrated a beneficial role to improve DED symptoms and signs in ADDE, EDE, and MDE. CONCLUSION QMR is an effective and well-tolerated treatment that seems to improve DED symptoms and signs in patients with severe DED. However, further studies are needed to confirm this.

Abstract
PURPOSE Dry eye disease has public health and economic significance. Platelet-rich plasma is rich in anti-inflammatory agents and growth factors, both beneficial for ocular surface repair. This study aimed to conduct a systematic review and meta-analysis to summarize the benefits of platelet-rich plasma for treating dry eye disease and its adverse effects. METHODS Prospective comparative studies using platelet-rich plasma as monotherapy for dry eye disease were included for efficacy assessment. Before-after studies were included for adverse events assessment. Data sources included PubMed, Google Scholar, Web of Science, and Scopus. A systematic review and meta-analysis protocol was pre-registered on PROSPERO (CRD42022347982). PRISMA guidelines were followed. The National Health Institute (NIH) quality assessment tool for before-after studies, the Cochrane risk of bias tool (RoB2), and the methodological index for non-randomized studies were used to assess the risk of bias. Heterogeneity was assessed using the I2 statistic. RESULTS 19 studies (10 comparative and 9 before-after) were included in the systematic review and meta-analysis. The occurrence rate of adverse effects was 2.6 % (95 % CI: 0.5 - 4.7). The pooled standardized mean difference (SMD) for dry eye symptoms was 0.81 (95 % CI: 0.25 - 1.37; I2 = 82 %; p < 0.00001; Z = 2.84, p = 0.004); tear quality was 0.44 (95 % CI: 0.06 - 0.81; I2 = 67 %; p = 0.003; Z = 2.26, p = 0.02); tear quantity was 0.45 (95 % CI: 0.03 - 0.88; I2 = 74 %; p = 0.0003; Z = 2.10, p = 0.04); and corneal staining 0.72 (95 % CI: 0.14 - 1.30; I2 = 85 %; p < 0.00001; Z = 2.43, p = 0.02). CONCLUSION The current study shows that platelet-rich plasma is efficacious in managing dry eye disease, significantly reducing dry eye signs and symptoms. Such significant improvements could translate to improved quality of life.

Abstract
Dry eye disease (DED) is a highly prevalent and debilitating condition. Hyaluronic acid (HA) is a naturally occurring glycosaminoglycan that has a long history as a safe and effective DED treatment. HA is frequently used as a comparator when assessing other topical DED treatments. This study aims to summarise and critically evaluate the literature describing all isolated active ingredients that have been directly compared with HA in the treatment of DED. A literature search was conducted in Embase using Ovid on the 24th of August 2021 and in PubMed including MEDLINE on the 20th of September 2021. Twenty-three studies met the inclusion criteria, 21 of which were randomised controlled trials. Seventeen different ingredients representing six treatment categories were compared with HA treatment. Most measures showed no significant difference between treatments, suggesting either equivalency of treatments or that studies were underpowered. Only two ingredients were represented in more than two studies; carboxymethyl cellulose treatment appears equivalent to HA treatment, while Diquafosol treatment appears superior to HA treatment. Drop-frequency varied from one to eight drops daily. No single study explained the choice of drop frequency. Nine studies used a HA concentration of 0.1% which may be below therapeutic levels. Nine studies reported using preserved formulations, six of them with differences in preservatives between the compared groups. Thirteen studies were financially linked to industry. No major complications were reported. Studies were not designed to find differences in treatment effects for different types or severities of DED. HA is a good comparator treatment when assessing other DED treatments, although consensus after decades of use is still lacking for best choice of concentration, molecular weight and drop tonicity. Well-designed studies are needed to determine an evidence-based standard for HA treatment to be used as comparator.

Abstract
PURPOSE To report the heterogeneity in methodology of clinical trials submitted to the US Food and Drug Administration (FDA) for approval of topical dry eye treatments. DESIGN Comparative analysis of clinical trials' methods. METHODS We reviewed the online, publicly available FDA database, application review files, ClinicalTrials.gov registry records, and journal articles for each FDA-approved topical dry eye treatment. For each trial, we extracted information about the study, patient demographics, treatment names and doses, sample size in each arm, and the measurement instrument in a systematic fashion. RESULTS Fourteen trials were included that assessed 5 topical treatments for dry eye (cyclosporine 0.05%, cyclosporine 0.09%, lifitegrast 5%, and loteprednol 0.25% eye drops and varenicline 0.03-mg nasal spray). Median treatment duration was 12 weeks (range, 2-24 weeks). In all trials, treatments, including varying concentrations of the same treatment, were compared with vehicle. Twelve trials (85.7%) evaluated a primary clinician-measured clinical sign, and 10 trials (71.4%) evaluated a primary patient-reported symptom. Corneal staining was the most frequently evaluated clinical sign primary outcome, reported in half (6 of 12) of the trials, and was graded using 4 different scoring systems. Conjunctival staining, conjunctival hyperemia, and tear production were each measured using 2 different scoring systems. Ocular discomfort, the only patient-reported symptom primary outcome, was measured using 5 different instruments. CONCLUSION A variety of outcome measures were used in these clinical trials. Clinically meaningful dry eye outcome measures and standardized measurements can optimize the assessment of and comparison of therapeutic benefits.
