Purpose of Review: Cyclosporine is a versatile immunomodulatory drug commonly employed in modern medicine. Although cyclosporine was initially used to prevent solid organ transplant rejection, its indications have extended to treat many inflammatory or autoimmune diseases. Cyclosporin is available for use in oral, intravenous, and topical forms, including eye drops to treat corneal and ocular surface conditions. It is naturally advantageous to administer cyclosporin directly into the eye, avoiding potential and dose limiting systemic adverse effects. However, the transition from systemic to topical administration has been a challenging one. This report reviews the evolution of ophthalmic cyclosporine treatment and explores its clinical impacts and future research directions., Recent Findings: Latest advancements in formulations - from oil-based solutions to nanomicelle and gel systems and waterless formulations - have improved the therapeutic efficacy and tolerability of topically applied cyclosporine, demonstrating greater effectiveness in treating ocular surface parameters compared to oil-based solution., Summary: Cyclosporine continues to be a safe and effective immunomodulatory drug in the field of ophthalmology to treat various chronic inflammatory ocular surface diseases and dry eye. Currently, there are several commercially available topical preparations available for ophthalmic use each with unique formulation and clinical outcomes., (Copyright © 2024 Wolters Kluwer Health, Inc.

Gavin Li,1 Esen Karamursel Akpek,2 Sumayya Ahmad1 1Department of Ophthalmology at the Icahn School of Medicine at Mount Sinai, New York, NY, USA; 2Ocular Surface Disease Clinic, Wilmer Eye Institute, Johns Hopkins University School of Medicine, Baltimore, MD, USACorrespondence: Sumayya Ahmad, New York Eye and Ear Infirmary, Icahn School of Medicine at Mount Sinai, 2520 30th Avenue, Long Island City, New York, NY, 11102, USA, Tel +1 (301)-473-3930, Fax +1 718-808-7757, Email sumayya.ahmad@gmail.comAbstract: Understanding the association between ocular surface disease and glaucoma is important for improving adherence to treatment and introducing practical solutions. While topical antihypertensive medications for glaucoma are well tolerated according to short-term studies, there is little evidence on their long-term effects. Since they are often required for many years, the effects of these drops on the ocular surface become important in regard to quality of life and adherence. In this nonsystematic review performed in April 2022, we summarize what is known about the relationship between glaucoma and ocular surface disease. Specifically, we examine how each class of topical glaucoma drops affects the ocular surface. We then review the treatment of ocular surface disease for patients on topical glaucoma therapy. Finally, we discuss treatments that may reduce or eliminate the burden of topical medications.Keywords: glaucoma, ocular surface disease, adherence

Purpose: To evaluate a commercially available dexamethasone intracanalicular insert to treat dry eye., Design: Single-center, double-masked randomized controlled trial., Participants: Patients with clinically significant aqueous-deficient dry eye (combined ocular surface staining score, ≥ 3 [0-12]; corneal fluorescein staining score, ≥ 2 [0-6]; and Schirmer's wetting, < 10 mm at 5 minutes in both eyes) with symptoms (dryness, eye discomfort, or visual fatigue, ≥ 30 [0-100]) despite treatment with at least 1 prescription drop and deemed candidates for topical steroid therapy., Methods: Seventy-five adult patients were enrolled. A 1:1 randomization sequence was used to determine which eye of each patient would receive the treatment (dexamethasone 0.4-mg intracanalicular insert with 30-day elution time) or sham (collagen plug). The fellow eye received the opposite treatment. Patients were masked to treatment assignment. Follow-up visits (at weeks 2, 4, and 6) were performed by a masked investigator., Main Outcome Measures: Dry eye parameters and patient symptoms were used for efficacy, and intraocular pressure (IOP) was used for safety assessment., Results: The severity of dry eye was comparable between the treatment arms (fellow eyes) at baseline. Eyes that received the dexamethasone insert showed significantly less corneal staining at week 4 (mean difference [MD], -0.55; 95% confidence interval [CI], -0.91 to -0.19) and conjunctival staining at week 4 (MD, -0.68; 95% CI, -1.05 to -0.30) and week 6 (MD, -0.34; 95% CI, -0.65 to -0.02). Schirmer's wetting was comparable between the two treatment arms. Although the patients reported less dryness in eyes that received the insert at week 4 (MD, -5.5; 95% CI, -11.4 to 0.4), no statistically significant differences were found in any patient-reported symptoms. At week 4, dexamethasone-treated eyes were more likely to show an IOP increase (by 5-10 mmHg; 9 eyes vs. 1 eye; relative risk, 9.00; 95% CI, 1.14-71.0). All cases of increased IOP were managed with short-term topical β-blockers and subsided., Conclusions: The dexamethasone intracanalicular insert may be considered a dropless dual treatment for clinically significant aqueous-deficient dry eye when topical steroid treatment is deemed appropriate., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2024 American Academy of Ophthalmology.

Objective: To assess the feasibility of using artificial intelligence (AI) to improve readability of online cataract surgery patient education materials (PEMs) in English and Spanish., Participants: Websites with information dedicated to educating patients about cataract surgery., Design: Comparative cross-sectional study., Methods: The first 50 patient-oriented websites containing PEMs related to cataract surgery were identified through online search. Website authorship was categorized as an institution, private practice, or medical organization. Websites were assessed qualitatively for information accuracy, the presence of narrative video content, and multilingual availability. Readability of PEMs was assessed using five validated reading formulas. A natural language processing platform was used to simplify PEMs in English and Spanish. Converted PEMs were reassessed for readability and accuracy., Results: A total of 32 institution, 7 private practice, and 11 medical organization sites were included. The overall average original reading grade level was 11.68 ± 1.59. After conversion, overall reading grade level improved to 7.94 ± 0.82 (p < 0.01). The first 10 results had better readability (10.40 ± 1.59) and reading ease (57.51 ± 9.24) compared to the subsequent 40 results (11.99 ± 1.43; p = 0.01; 47.64 ± 8.59; p < 0.01). Converted simplified Spanish text had an average reading ease score of 61.17 ± 5.39 (8-9th grade level). Native Spanish text reading ease improved from 57.41 ± 5.24 to 71.78 ± 5.24 (p < 0.01) following conversion (7th-grade level)., Conclusion: AI conversion can enhance the readability of online PEMs on cataract surgery, while maintaining accuracy and content integrity, thereby improving accessibility and comprehensibility for a wider audience., (Copyright © 2024 Canadian Ophthalmological Society.

Purpose: The aim of this study was to report long-term outcomes of patients who have undergone Boston type I keratoprosthesis (KPro) surgery., Methods: This study was a retrospective review. Inclusion criteria were KPro surgery between 2006 and 2012 and at least 10 years of follow-up. Demographics, ocular history, surgery indication, clinical variables, and postsurgical outcomes were recorded. Descriptive statistical analysis was performed., Results: We identified 75 patients with KPro implantation, and 17 patients with at least 10 years of follow-up (median = 11.1 years; range, 10.0-12.8 years) were included. Of 17 eyes, 11 (64.8%) had their original device in situ, 3 (17.6%) had their second device in situ, 1 (5.9%) had the device removed and replaced with a donor keratoplasty, and 2 (11.8%) were enucleated. At the last follow-up, 11 eyes (64.7%) were able to maintain improvement in vision, 5 (29.4%) had worsened vision, 1 (5.9%) had stable vision, and 9 (52.9%) had visual acuity

Purpose: The purpose of this study was to investigate the impact of demographic characteristics and psychiatric comorbidity on the prevalence of dry eye disease in the American geriatric population., Methods: Data were collected from a 2011 nationwide sample of Medicare beneficiaries aged 65 years and older (N = 1,321,000). Age, sex, race/ethnicity, residential area, climate region, and income, along with psychiatric comorbidities including depression and anxiety, were collected. Multivariable logistic regression models were used to assess the relationship between demographic and psychiatric factors and the prevalence of dry eye disease., Results: Among 21,059 patients with clinically significant dry eye, women had higher odds of having dry eye compared with men [odds ratio (OR) 2.03, 95% confidence interval (1.97-2.10)]. Asian and Native American patients had increased odds of having dry eye compared with White patients [OR 1.85 (1.69-2.02) and OR 1.51 (1.19-1.93)], while Black patients were less likely to have dry eye [OR 0.83 (0.79-0.87)]. Patients aged 75 to 84 years and 85+ were more likely to have dry eye compared with those aged 65 to 74 years [OR 1.49 (0.45-1.53) and OR 1.54 (1.48-1.60)]. Having both depression and anxiety were associated with higher odds of having dry eye [OR 2.38 (2.22-2.55)] compared with having depression alone [OR 1.95 (1.86-2.04)] or anxiety alone [OR 2.22 (2.10-2.35)]., Conclusions: Significant racial and regional disparities in dry eye prevalence were found. Psychiatric association with dry eye varied with age, sex, race, and residence region. Further research is needed to comprehend the underlying mechanisms, implications, and to address disparities in the diagnosis and management of dry eye., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2024 Wolters Kluwer Health, Inc.

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., (Copyright © 2024 The Author(s).

Purpose: We sought to introduce the materials, design, and biocompatibility of a flexible and suturable artificial corneal device., Methods: Single-piece, fully synthetic, optic-skirt design devices were made from compact perfluoroalkoxy alkane. The skirt and the optic wall surfaces were lined with a porous tissue ingrowth material using expanded polytetrafluoroethylene. Full-thickness macroapertures around the skirt perimeter were placed to facilitate nutrition of the recipient cornea. Material properties including the skirt's modulus of elasticity and bending stiffness, optic light transmission, wetting behavior, topical drug penetrance, and degradation profile were evaluated., Results: The final prototype suitable for human use has a transparent optic with a diameter of 4.60 mm anteriorly, 4.28 mm posteriorly, and a skirt outer diameter of 6.8 mm. The biomechanical and optical properties of the device closely align with the native human cornea with an average normalized device skirt-bending stiffness of 4.7 kPa·mm4 and light transmission in the visible spectrum ranging between 92% and 96%. No optical damage was seen in the 36 devices tested in fouling experiments. No significant difference was observed in topical drug penetrance into the anterior chamber of the device implanted eye compared with the naïve rabbit eye., Conclusions: The flexibility and biocompatibility of our artificial cornea device may offer enhanced tissue integration and decreased inflammation, leading to improved retention compared with rigid keratoprosthesis designs., Translational Relevance: We have developed a fully synthetic, flexible, suturable, optic-skirt design prototype artificial cornea that is ready to be tested in early human feasibility studies.

Sjögren's disease (SjD) is a systemic autoimmune exocrinopathy with key features of dryness, pain, and fatigue. SjD can affect any organ system with a variety of presentations across individuals. This heterogeneity is one of the major barriers for developing effective disease modifying treatments. Defining core disease domains comprising both specific clinical features and incorporating the patient experience is a critical first step to define this complex disease. The OMERACT SjD Working Group held its first international collaborative hybrid meeting in 2023, applying the OMERACT 2.2 filter toward identification of core domains. We accomplished our first goal, a scoping literature review that was presented at the Special Interest Group held in May 2023. Building on the domains identified in the scoping review, we uniquely deployed multidisciplinary experts as part of our collaborative team to generate a provisional domain list that captures SjD heterogeneity., Competing Interests: Declaration of competing interest Valerie Devauchelle reports receinving funds for consulting to Novartis, Abbvie, Fresenius Kabi.

Purpose: To assess the web accessibility and readability of patient-oriented educational websites for cataract surgery., Design: Cross-sectional electronic survey., Participants: Websites with information dedicated to educating patients about cataract surgery., Methods: An incognito search for "cataract surgery" was performed using a popular search engine. The top 100 patient-oriented cataract surgery websites that came up were included and categorized as institutional, private practice, or medical organization according to authorship. Each site was assessed for readability using 4 standardized reading grade-level formulas. Accessibility was assessed through multilingual availability, accessibility menu availability, complementary educational video availability, and conformance and adherence to the Web Content Accessibility Guidelines (WCAG) 2.0. A standard t test and chi-square analysis were performed to assess the significance of differences with regard to readability and accessibility among the 3 authorship categories., Main Outcome Measures: The main outcome measures were the website's average reading grade level, number of accessibility violations, multilingual availability, accessibility menu availability, complementary educational video availability, accessibility conformance level, and violation of the perceivable, operable, understandable, and robust (POUR) principles according to the WCAG 2.0., Results: A total of 32, 55, and 13 sites were affiliated with institutions, private practice, and other medical organizations, respectively. The overall mean reading grade was 11.8 ± 1.6, with higher reading levels observed in private practice websites compared with institutions and medical organizations combined (12.1 vs. 11.4; P = 0.03). Fewer private practice websites had multiple language options compared with institutional and medical organization websites combined (5.5% vs. 20.0%; P = 0.03). More private practice websites had accessibility menus than institutions and medical organizations combined (27.3% vs. 8.9%; P = 0.038). The overall mean number of WCAG 2.0 POUR principle violations was 17.1 ± 23.1 with no significant difference among groups. Eighty-five percent of websites violated the perceivable principle., Conclusions: Available patient-oriented online information for cataract surgery may not be comprehensible to the general public. Readability and accessibility aspects should be considered when designing these resources., Financial Disclosure(s): The author(s) have no proprietary or commercial interest in any materials discussed in this article., (Copyright © 2023 American Academy of Ophthalmology.

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., (Copyright © 2023 Elsevier Inc.

Purpose: To examine the ocular signs and symptoms in participants of the Sjögren's International Collaborative Clinical Alliance cohort, and to compare them across Sjögren's disease (SjD) status., Methods: Our study population comprised 3380 Sjögren's International Collaborative Clinical Alliance participants who had no missing data relevant to this study. Participants' SjD status was assessed using the updated 2016 American College of Rheumatism/European League Against Rheumatism SjD classification criteria. Participants completed baseline questionnaires of ocular symptoms and underwent ocular examinations. Differences in the ocular signs and symptoms between SjD and non-SjD groups were assessed. We used multivariable linear and linear mixed-effects models to investigate the impact of SjD on Ocular Surface Disease Index-6 and OSS., Results: Among 1532 participants classified as SjD, their Ocular Surface Disease Index-6 did not clinically differ from those classified as non-SjD (adjusted difference, -0.97; 95% confidence interval, -1.52 to -0.41). However, SjD participants exhibited an elevated ocular staining score (adjusted difference, 3.47; 95% confidence interval, 3.36-3.57; P < 0.001) compared with non-SjD participants. In addition, SjD was associated with increased odds of ocular signs, such as reduced tear break-up time, abnormal Schirmer I test, and corneal abnormalities, and was strongly related to more intense corneal and conjunctival staining, as well as additional corneal staining points., Conclusions: SjD is associated with a higher risk of ocular signs and pathology compared with non-SjD, whereas ocular symptoms remain similar. In addition, corneal abnormalities and corneal staining patterns could serve as a potential biomarker in identifying SjD-related dry eye.

Purpose: This study aimed to review the demographics, clinical characteristics, and long-term outcomes of therapeutic penetrating keratoplasty (TPK) performed in a tertiary eye care hospital., Methods: Case records of 149 therapeutic transplants (135 patients) that were performed during the calendar year 2016 were retrospectively analyzed, and outcomes were measured until 3 years of follow-up. Information on demographics, presentation characteristics, keratoplasty indications, offending microbe, and secondary surgical interventions was studied. The final outcome was classified in terms of therapeutic, anatomical, and functional outcomes., Results: The median age of the recipients was 55 years with 61% men. The most common indications for TPK were perforated infectious ulcer (45.9%), nonhealing ulcers (29.9%), and graft infections (17.4%). Fungal etiology was noted in 61.2% and bacterial etiology in 17.4% of the eyes. Therapeutic success was achieved in 130 eyes (89%) at the end of 1 month. Anatomical success was achieved in 130 (98.5%) and 88 patients (86.3%) at the end of 1 and 6 months, respectively. At the 6-month time point, 78 patients (76.5%) attained functional success with vision better than light perception. Three-year follow-up data were available for 23.7% of recipients, of which only 12 patients (37.5%) retained a clear graft either after a primary therapeutic or secondary optical keratoplasty., Conclusion: Therapeutic keratoplasty is highly effective in eradicating infection and providing anatomical integrity. However, timely intervention can aid in achieving the best functional outcome., Competing Interests: None

Purpose: To report the biological stability and postoperative outcomes of a second-generation, single-piece, flexible synthetic cornea in a rabbit model., Methods: Device materials and design were amended to enhance biointegration. Optic skirt design devices were made from compact perfluoroalkoxy alkane with porous expanded polytetrafluoroethylene ingrowth surface overlying the skirt and optic wall. Sixteen devices were implanted into intrastromal pocket in rabbit eyes. Rabbits were randomly assigned to 6- and 12-month follow-up cohorts (n = 8 in each) postoperatively. Monthly examinations and optical coherence tomography assessed cornea-device integration, iridocorneal angle, optic nerve, and retina., Results: There were no intraoperative complications. All devices were in situ at exit, with clear optics. No retroprosthetic membrane, glaucoma, cataract formation, or retinal detachment was observed. Two rabbits in the 6-month group had mild, focal anterior lamella thinning without retraction adjacent to the optic near tight sutures. Three postoperative complications occurred in the 12-month group. One rabbit diagnosed with endophthalmitis was euthanized on day 228. Mild sterile focal retraction of anterior lamella occurred in two rabbits, which were terminated on days 225 and 315. Light microscopic examination of enucleated globes demonstrated fibroplasia with new collagen deposition into the porous scaffold without significant inflammation, encapsulation, or granuloma formation., Conclusions: Clinical evaluations, imaging, and histopathological findings indicate favorable outcomes of this synthetic corneal device in a rabbit model. Early feasibility studies in humans are being planned., Translational Relevance: Favorable 12-month results of the device in rabbits demonstrate vision-restoring potential in corneally blind individuals at high risk of failure with donor keratoplasty.

Purpose of Review: Ocular surface disease is a prevalent, diverse group of conditions that cause patient discomfort and decreased visual acuity and present considerable expense to both patients and healthcare systems. Autologous serum eye drops are a topical treatment modality derived from the patient's own blood. Use of serum eye drops for ocular surface disease has been promising due to biochemical similarities to endogenous tears., Recent Findings: Use of serum eye drops for moderate to severe ocular surface diseases such as dry eye, corneal epithelial defects, and inflammatory conditions has become more prevalent. Recent studies have demonstrated that the use of serum eye drops is well-tolerated by patients and associated with improvement in patient-reported outcomes and objective dry eye parameters. Production of serum eye drops may vary, treatment costs can be significant, and the quality of evidence for serum eye drop use published from randomized controlled trials is modest, particularly for long-term treatment. Accessibility remains an area for improvement and may be complemented by allogeneic serum eye drops., Summary: Serum eye drops are frequently used as a safe, well-tolerated, and effective treatment for ocular surface disease. Further research is needed to assess long-term outcomes and improve accessibility., (Copyright © 2021 Wolters Kluwer Health, Inc. All rights reserved.)

Purpose: To assess whether cross-linking the carrier donor cornea of the Boston Keratoprosthesis (BKPro) improves retention of the device in participants at high risk for keratolysis., Design: Prospective, double-masked, randomized clinical trial., Methods: In this multicenter study, 68 adult participants who were scheduled for BKPro implantation were enrolled. Masked participants were randomized to receive either a cross-linked (CXL) or non-cross-linked (non-CXL) donor corneal carrier. The Kaplan-Meier event-free survival was determined by the product-limit method and compared by the log-rank test to examine whether survival curves were different between the CXL and non-CXL groups. The primary outcome of the study was time from surgery to BKPro removal. The secondary endpoint was 12-month retention rate., Results: A total of 68 participants were enrolled and randomized 1:1 to each group. The average age at the time of surgery was 62 (range = 24-89) years, and 42 participants (62%) were male. The overall BKPro retention rate was 70% during a mean follow-up time of 93 (range = 6-201) weeks. Twenty BKPros were removed, 10 in the CXL group and 10 in the non-CXL group, with 18 requiring removal because of sterile keratolysis. There was no difference in the time to removal between the groups during the study (P = .910). At 12 months, there was no significant difference in the retention rate in the CXL group (94%) vs the non-CXL group (82%, P = .150)., Conclusions: In this prospective study, cross-linking of the carrier cornea prior to BKPro implantation did not reduce the incidence of sterile keratolysis or increase device retention among participants at high risk for retention failure., (Copyright © 2022 Elsevier Inc.

Importance: Dry eye disease (DED) is a common public health problem with significant impact on vision-related quality of life and well-being of patients. Medications with rapid onset of action and a good tolerability profile remain an unmet need., Objective: To assess efficacy, safety, and tolerability of a water-free cyclosporine ophthalmic solution, 0.1% (CyclASol [Novaliq GmbH]), applied twice daily in DED compared with vehicle., Design, Setting, and Participants: CyclASol for the Treatment of Signs and Symptoms of Dry Eye Disease (ESSENCE-2) was a phase 3, multicenter, randomized, double-masked, vehicle-controlled clinical study conducted from December 5, 2020, to October 8, 2021. Following a 14-day run-in period with an artificial tear administered 2 times per day, eligible participants were randomly assigned 1:1 to the treatment groups. Patients with moderate to severe DED were included in the study., Interventions: Cyclosporine solution vs vehicle administered 2 times per day for 29 days., Main Outcomes and Measures: The primary end points were changes from baseline in total corneal fluorescein staining (tCFS; 0-15 National Eye Institute scale) and in dryness score (0-100 visual analog scale) at day 29. Conjunctival staining, central corneal fluorescein staining, and tCFS responders were also assessed., Results: A total of 834 study participants were randomly assigned to cyclosporine (423 [50.7%]) or vehicle (411 [49.3%]) groups at 27 sites. Participants had a mean (SD) age of 57.1 (15.8) years, and 609 (73.0%) were female individuals. The majority of participants self-identified in the following race categories: 79 Asian (9.5 %), 108 Black (12.9%), and 635 White (76.1%). Participants treated with cyclosporine solution had greater improvement in tCFS (-4.0 grades) than the vehicle group (-3.6 grades) at day 29 (change [∆] = -0.4; 95% CI, -0.8 to 0; P = .03). The dryness score showed treatment benefits from baseline in both groups: -12.2 points for cyclosporine and -13.6 points for vehicle (∆ = 1.4; 95% CI, -1.8 to 4.6; P = .38). In the cyclosporine group, 293 participants (71.6%) achieved clinically meaningful reductions of 3 grades or higher in tCFS vs 236 (59.7%) in the vehicle group (∆ = 12.6%; 95% CI, 6.0%-19.3%; P < .001). These responders showed greater improvement in symptoms at day 29 including dryness (∆ = -4.6; 95% CI, -8.0 to -1.2; P = .007) and blurred vision (Δ = -3.5; 95% CI, -6.6 to -4.0; P = .03) compared with nonresponders., Conclusions and Relevance: The ESSENCE-2 trial confirmed that treatment with a water-free cyclosporine solution, 0.1%, results in early therapeutic effects on the ocular surface compared with vehicle. The responder analyses suggest that the effect is clinically meaningful in 71.6% of participants in the cyclosporine group., Trial Registration: ClinicalTrials.gov Identifier: NCT04523129.

Purpose: To develop a screening questionnaire to identify patients with dry eye with a high likelihood of having underlying Sjögren syndrome (SS)., Methods: This was a cross-sectional study of participants with dry eye complaints who were self-referred or referred by an ophthalmologist to the Sjögren's International Collaborative Clinical Alliance study. Symptoms and ocular surface examination findings were candidate predictors. Univariable and multivariable logistic regression analyses were performed to estimate odds ratios (ORs) and 95% confidence intervals (95% CI) for the association of a symptom and/or ocular sign with SS. Area under the receiver operating characteristic curve (AUC) was used to summarize the predictive ability of different regression models and the derived likelihood score., Results: Four questions were statistically significant in the final multivariable model: 1) Is your mouth dry when eating a meal? [Yes = OR 1.63 (1.18-2.26)]; 2) Can you eat a cracker without drinking a fluid or liquid? [No = OR 1.46 (1.06-2.01)]; 3) How often do you have excessive tearing? [None of the time = OR 4.06 (1.81-9.10)]; and 4) Are you able to produce tears? [No = OR 2.24 (1.62-3.09)]. The SS likelihood score had an AUC of 0.70 (95% CI, 0.66-0.73), and when including tear break-up time and conjunctival staining, it yielded an AUC of 0.79 (95% CI, 0.77-0.82)., Conclusions: This questionnaire can be used to identify patients with dry eye with a high likelihood of having SS. With future refinement and validation, this screening tool could be used alone or in combination with examination findings to identify patients with SS earlier, thereby facilitating better clinical outcomes., Competing Interests: V.

Purpose: Systemic implications necessitate the identification of dry eye patients with Sjögren syndrome (SS). This study aims to explore the utility of tear MUC5AC and inflammatory cytokine levels in the differential diagnosis of SS-related dry eye., Methods: A prospective, observational, case-control study was conducted on 62 patients (those with a definitive diagnosis of SS dry eye, non-SS dry eye, and age-matched healthy controls with no dry eye). Clinical evaluations included the following tests in the order listed here: noninvasive tear break-up time, osmolarity, tear sampling, Schirmer test without anesthesia, and ocular surface staining (lissamine green for conjunctiva and fluorescein for cornea). Tear MUC5AC levels were assessed with enzyme-linked immunosorbent assay, and cytokines [interferon-gamma, tumor necrosis factor alpha, interleukin (IL)-6, IL-17a, IL-1β, IL-8, IL-10, and IL-12p70] were measured using a Luminex assay in a masked fashion., Results: The Bulbar conjunctival lissamine green staining score was significantly greater in patients or controls with SS versus non-SS dry eye. This greater conjunctival staining was associated with a reduction in tear MUC5AC (B = -17.8 ng/mL, 95% confidence interval = -31.8 to -3.9, P = 0.01). Among the tear cytokines, a significant association was found between IL-8 levels (hazard ratio [HR] = 1.002, 95% confidence interval = 1.000-1.003, P = 0.03) and SS diagnosis. When patients were stratified based on tear MUC5AC levels, significantly increased tear IL-8 levels were detected in patients with SS dry eye but not with non-SS dry eye, in comparison with healthy controls., Conclusions: Tear levels of goblet cell-specific MUC5AC combined with IL-8 can potentially serve as a useful biomarker for differential diagnosis of SS dry eye from non-SS dry eye.

Purpose: The purpose of this study was to report the adverse effects of the COVID-19 pandemic on the clinical outcomes of infectious keratitis in South India., Methods: Two hundred fifty-eight patients presented with infectious keratitis at 6 tertiary care centers when strict travel restrictions were in place from March 24 to May 31, 2020. Case records were collected retrospectively and analyzed for demographics, type of initial treatment, length of delay in presentation, microbiological diagnosis, clinical course, and final treatment outcome., Results: The mean age of the patients was 49.2 years, with most of them (61.2%) being male. Forty-one patients (15.9%) did not receive any treatment for at least a week after the onset of symptoms. One hundred eight patients (41.9%) presented with severe ulcer (32 had a frank perforation). Resolution of the infection was achieved only in 103 patients (45.6%). A total of 90 patients (39.8%) with ulcers had a perforation, yet only 29 patients (32.2%) could receive keratoplasty because of the unavailability of donor tissues. At the end of 6-month follow-up, 47 patients had anatomical failure (loss of globe) and 12 additional patients had functional failure (total permanent vision loss)., Conclusions: Delay in presentation and acute shortage of donor corneal tissues for emergency keratoplasty because of the COVID-19 pandemic had a grave impact, resulting in irreversible blindness in a significant number of patients., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2021 Wolters Kluwer Health, Inc.

Objective: Although symptom relief is a critical aspect for successful drug development in Sjögren's disease, patient experiences with Sjögren's-related symptoms are understudied. Our objective was to determine how pain, dryness, and fatigue, the cardinal symptoms of Sjögren's disease, drive cluster phenotypes., Methods: We used data from the Sjögren's International Collaborative Clinical Alliance (SICCA) Registry and a Sjögren's Foundation survey. We performed hierarchical clustering of symptoms by levels of dryness, fatigue, and pain. Using international and US cohorts, we performed multiple logistic regression analysis to compare the clusters, which included comparisons of differences in symptoms, quality of life (QoL), medication use, and systemic manifestations., Results: Four similar clusters were identified among 1,454 SICCA registrants and 2,920 Sjögren's Foundation survey participants: 1) low symptom burden in all categories (LSB); 2) dry with low pain and low fatigue (DLP); 3) dry with high pain and low to moderate fatigue (DHP); and 4) high symptom burden in all categories (HSB). Distribution of SICCA registrants matching the symptom profile for each cluster was 10% in the LSB cluster, 30% in the DLP cluster, 23% in the DHP cluster, and 37% in the HSB cluster. Distribution of survey participants matching the symptom profile for each cluster was 23% in the LSB cluster, 14% in the DLP cluster, 21% in the DHP cluster, and 42% in the HSB cluster. Individuals in the HSB cluster had more total symptoms and lower QoL but lower disease severity than those in the other clusters. Despite having milder disease as measured by laboratory tests and organ involvement, individuals in the HSB cluster received immunomodulatory treatment most often., Conclusion: We identified 4 symptom-based Sjögren's clusters and showed that symptom burden and immunomodulatory medication use do not correlate with Sjögren's end-organ or laboratory abnormalities. Findings highlight a discordance between objective measures and treatments and offer updates to proposed symptom-based clustering approaches., (© 2022 The Authors.

Objective: To assess anti-Ro52 and anti-Ro60 serologic profiles as markers of clinically relevant phenotypic subsets of patients with Sjögren's syndrome (SS)., Methods: From a cohort of 839 consecutive patients with suspected or established SS seen in our multidisciplinary SS center, we compared the association of key phenotypic features in 390 patients who fulfilled SS classification criteria and in the parent cohort, stratifed by the presence of both anti-Ro60 and anti-Ro52, anti-Ro60 alone, and anti-Ro52 alone., Results: The SS cohort included 227 patients (58%) with both anti-Ro60 and anti-Ro52, 65 (17%) with anti-Ro60 alone, 58 (15%) with anti-Ro52 alone, and 40 (10%) with neither antibody. Those with both anti-Ro60 and anti-Ro52 had a significantly increased prevalence of abnormal ocular surface staining, focal lymphocytic sialadenitis with focus score ≥1, antinuclear antibody ≥1:320, anti-SSB/La, rheumatoid factor, and IgG ≥15.6 gm/liter (P < 0.0016 for all). The groups with isolated anti-Ro52 and anti-Ro60 were equivalent to each other in their phenotypic associations, except for rheumatoid factor, which was higher in the anti-Ro52 alone group. The associations of these Ro antibody serologic profiles were similar in the parent cohort, except for additional associations with salivary gland enlargement and parotid gland ultrasound score., Conclusion: SS patients with both anti-Ro60 and anti-Ro52 antibodies are distinguished by a higher prevalence of markers of B-cell hyperactivity and glandular inflammation. Antibody reactivity to both Ro60 and Ro52 may thus serve as an important inclusion criterion for SS patients in clinical trials where the therapeutic agent targets pathways mediating these pathogenic abnormalities., (© 2021 American College of Rheumatology.)

Differentiating patients with Sjögren's syndrome (SS)-associated dry eye from non-SS dry eye is critical for monitoring and appropriate management of possible sight- or life-threatening extraglandular complications associated with SS. We tested whether reduced tear levels of immunoregulatory thrombospondin (TSP)-1, which also inhibits matrix metalloproteinase (MMP)-9, would reflect SS pathogenesis aiding the identification of patients with SS-dry eye. Total of 61 participants, including healthy controls (n = 20), patients with non-SS dry eye (n = 20) and SS-dry eye (n = 21) were enrolled prospectively. Tear TSP-1 and MMP-9 levels were measured using a custom magnetic bead-based multi-plex assay in a masked manner. Analyte concentrations were assessed further according to ocular surface and tear film parameters. Relative to median tear TSP-1 (308 ng/ml) and MMP-9 (1.9 ng/ml) levels in the control group, significantly higher proportion of patients with SS-dry eye than non-SS had lower tear TSP-1 levels (55% vs. 29%, odds ratio [OR] = 3, 95% confidence interval [CI] = 1.64 to 5.35, p < 0.05) and higher tear MMP-9 levels (65% vs. 24%, OR = 5.8, 95% CI = 4.46 to 19.81, p < 0.05), respectively. The tear TSP-1/MMP-9 ratio was significantly reduced in patients with SS-dry eye compared to non-SS (B = -2.36, 95% CI = -3.94 to -0.0.79, p < 0.05), regardless of tear MMP-9 levels. Patients with a lower ratio were 2.3 times more likely to have SS (OR = 0.28, 95% CI = 0.1 to 0.75, p < 0.05). This ratio showed significant inverse correlations with clinical parameters (conjunctival and corneal staining scores). Our results denote that tear TSP-1/MMP-9 ratio can be useful in identifying patients with dry eye with underlying SS and used as a screening test., (© 2022 The Authors.

Purpose: The purpose of this study was to report trends in the prevalence of early graft failure after endothelial keratoplasty in the United States., Methods: Descemet membrane endothelial keratoplasty (DMEK) and Descemet stripping automated endothelial keratoplasty (DSAEK) graft volumes were collected from records maintained by 6 major eye banks in the United States from January 1, 2013, to December 31, 2018. The prevalence and presumed cause of early graft failures (defined as a graft with persistent edema or regrafted within 8 weeks after keratoplasty) each year were sourced from surgeon-reported adverse events. Failed graft cases from the 3 eye banks were compared with nonfailures at the donor and recipient levels to perform subset analysis of factors associated with early graft failure., Results: A total of 51,887 endothelial keratoplasty tissues were distributed during the study period; 72% were DSAEK grafts. The total number of early graft failures reported was 168 of 14,284 (1.18%) for DMEK and 322 of 37,603 (0.86%) for DSAEK. Early DMEK failures decreased from 2013 (7.69%) to 2018 (0.68%). In generalized linear mixed model analyses adjusting for donor tissue characteristics, recipient age, and diagnosis, an association of borderline significance was found between higher donor age and early failure [odds ratio (95% confidence interval): 1.03 (1.00-1.05); unit change of 1 yr] and DSAEK [odds ratio 1.02 (1.00-1.04); unit of change 1 yr] cases., Conclusions: The proportion of early graft failures in DMEK decreased over time and was comparable with failure rates in DSAEK at the end of the study period.

To gain insight into the Sjögren's disease (SjD) patient experience using a survey generated by patients and providers. We evaluated the results of the 2016 Sjögren's Foundation survey, with 25 questions designed in a collaborative effort between the Foundation, patients with SjD, SjD provider experts, and a marketing research company. We used descriptive statistics to provide a thorough understanding of SjD demographics, symptoms, quality of life (QoL), cost, and treatments. Analyses revealed high symptoms, QoL, and financial burdens in SjD. Dry mouth and eye were the most commonly reported symptoms (94 and 93%, respectively). The most frequent extra-glandular symptoms included fatigue, dry or itchy skin, and morning stiffness. The top three aspects of QoL most impaired included (i) sex life (53%), (ii) participating in hobbies/social activities/extracurricular activities (52%), and (iii) job/career or ability to work (49%). SjD respondents commonly reported taking health food supplements/remedies, vitamin D, and exercising, in addition to taking treatments for symptomatic dryness. SjD costs were high, including a total yearly cost, on average, of $2026 for dental care. SjD respondents reported that dryness and risk factors for lymphoma and fatigue are essential to address with new therapies. In this comprehensive overview of the SjD experience, we demonstrated a high burden of disease to SjD respondents, including symptoms, QoL, and financial burden. We also identify the top goals of therapy for new systemic SjD therapies. Key Points • The top three symptoms or signs that patients with Sjögren's hope new treatments will address are dryness, fatigue, and reduction in lymphoma or blood cancer risk • The top aspects of quality of life reported to be impaired by Sjögren's are sex life, hobbies, social activities and extracurricular activities, job/career or ability to work, and finding the correct word during conversations • Patients with Sjögren's have a yearly mean dental cost of $2026 but also have high costs associated with prescription medications, healthcare appointments, over-the-counter medications, alternative therapies, and medical equipment., (© 2022.

Objective: The objective of this study was to examine the association of smoking with Primary Sjögren syndrome (pSS) classification and pSS diagnostic test results. We hypothesized that past and current smokers would have lower odds of being classified as having Sjögren syndrome (SS) and lower odds of having abnormal individual SS diagnostic test results compared with nonsmokers., Methods: Participants with suspected or established pSS were enrolled into the Sjögren's International Collaborative Clinical Alliance (SICCA) registry and had oral, ocular, and rheumatologic examinations performed; blood and saliva samples collected; and labial salivary gland biopsy examinations performed; they also completed questionnaires at baseline. Logistic regression was used to determine whether smoking status was associated with pSS classification and individual pSS diagnostic test results., Results: A total of 3514 participants were enrolled in SICCA. A total of 1541 (52.9%) met classification criteria for pSS. Compared with never smokers, current smokers had reduced odds of being classified as having pSS, reduced odds of having a focus score ≥ 1 and serologic positivity for anti-SSA/anti-SSB antibodies, and lower odds of having abnormal signs or test results of dry eye disease. Compared with never smokers, past smokers did not have a statistically significant reduction in odds of being classified as having pSS and of having abnormal individual pSS diagnostic test results., Conclusion: Compared with never smokers, current smokers in the SICCA cohort had lower odds of being classified as having pSS, lower odds of exhibiting abnormal signs and test results for dry eye disease, and lower odds of having a labial salivary gland biopsy supportive of pSS classification. Such negative associations, however, do not suggest that current smoking is of any benefit with respect to pSS., (© 2021 The Authors.

Purpose: Managing glaucoma after Boston type 1 keratoprosthesis (KPro) surgery remains challenging. We herein assessed the fitness of commonly used clinical tests to evaluate glaucoma in KPro eyes versus eyes with penetrating keratoplasty (PK) as controls., Methods: Sixteen patients with KPro and 14 patients with PK tested in an identical manner. After the 10-2 visual field with size V stimulus, intraocular pressure (IOP) was estimated with palpation by the first observer. Then, retinal nerve fiber layer (RNFL) thickness analysis was performed twice using optical coherence tomography by an ophthalmic photographer, before and after a short break. After the second observer estimated the IOP, the visual field was repeated. Finally, color photographs of the optic disk were captured by an ophthalmic photographer. The cup-to-disk ratio was assessed by 2 masked observers, at 2 different time points, in a random manner. Agreements between and within observers and reliability of repeated measurements were evaluated using the intraclass correlation coefficient (ICC) and Bland-Altman plots., Results: Inter-rater agreement of palpation IOP estimate was moderate for eyes with KPro (ICC = 0.47) and fair for eyes with PK (ICC = 0.27). Visual field and RNFL thickness showed high test-retest reliability in both KPro and PK eyes (ICC > 0.80 for both). Inter-rater agreement of cup-to-disk ratio assessments was substantial in eyes with both KPro (ICC = 0.62) and PK (ICC = 0.70)., Conclusions: The 10-2 visual field and RNFL thickness seem sufficiently repeatable and might allow the detection of glaucoma progression in KPro eyes. Such testing is important, given limited inter-rater agreement regarding the palpation IOP estimate., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2021 Wolters Kluwer Health, Inc.

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

Purpose: To evaluate the clinical performance and biocompatibility of a novel synthetic corneal device., Methods: Synthetic, single-piece, foldable, suturable, optic-and-skirt design prototype devices were fabricated using expanded polytetrafluoroethylene. A combination of intralamellar and full-thickness penetrating techniques was used for implantation. A topical antibiotic-steroid regimen was used postoperatively. Rabbits were examined weekly using penlight and at monthly intervals under an operating microscope with integrated optical coherence tomography. Optical quality, retention, and complication rates at 3 and 6 months were assessed., Results: Nineteen rabbits underwent surgery. There were no device-related intraoperative complications. Creation of lamellar pocket was problematic in 2 younger rabbits with inadequate chamber depth. Two rabbits had early postoperative infectious keratitis attributed to bandage contact lens wear, which was ceased. Rabbits were treated using fourth-generation fluoroquinolone drops and did well over a period of 6 months without device extrusion or further complications. Four other rabbits had late postoperative infectious keratitis because of exposed suture(s), which progressed to endophthalmitis. One rabbit had sterile keratolysis and retraction of the anterior corneal lamella. There was no retinal detachment, glaucoma, anterior or posterior synechiae, or cataract formation in any of the rabbits. All devices remained in situ with clear optics without spoliation. Light microscopic examination of the globes demonstrated intact epithelium overlying the skirt and new collagen integration into the porous structure of the skirt without significant inflammation., Conclusion: Our results demonstrated favorable short-term anatomical clinical outcomes of this novel synthetic corneal prosthesis. Further studies are warranted to characterize the biointegration of this device.

Purpose: To identify barriers and facilitators to adopting deep anterior lamellar keratoplasty (DALK) for nonendothelial corneal pathology., Methods: An anonymous survey consisting of 22 multiple choice and free text questions was designed to gather information on demographic factors of surgeons and DALK surgical practices. The survey was emailed to members of the kera-net, a global online corneal surgeon/surgery platform., Results: A total of 100 surgeons completed the survey, most of whom practice in the United States (73%). Most surgeons (89%) reported performing DALK. Surgeons who did not learn DALK during fellowship (34%) tended to be in practice for higher numbers of years (P < 0.001). Surgeons in private practice are more likely to perform DALK versus those in other settings (92.7% vs. 80.8%, P = 0.087). Surgeons performing more corneal surgeries (at least 100 per year) are more likely to perform DALK than those who perform fewer than 100 per year (52% vs. 14%, P = 0.01). Surgeons who perform Descemet membrane endothelial keratoplasty are more likely to perform DALK than those who do not (81.7% vs. 18.3%, P = 0.014). There was also a positive correlation between PK and DALK surgical volumes (Spearman rank correlation coefficient = 0.57, P < 0.001). The main reasons for surgeon preference for DALK over PK were a desire to preserve the endothelium, intraoperative safety, and decreased complications. Longer surgical time and low patient volume were cited as barriers to adoption of DALK., Conclusions: Alterations in DALK technique that reduce surgical time and providing more learning opportunities for DALK might improve adoption., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2020 Wolters Kluwer Health, Inc.

Purpose: Among adult individuals with dry eye, assess the self-reported impact of the COVID-19 pandemic on (1) dry eye-related visual function, (2) reading efficiency, and (3) dry eye treatments used., Methods: In June-July 2020, we conducted an online survey of adults with dry eye who spent at least somewhat more time at home during the pandemic than before. Consistent with TFOS DEWS II guidelines, we categorized respondents into mild, moderate, or severe dry eye based on treatment usage., Results: We included 388 respondents: 97 respondents (25%) with mild, 80 (21%) with moderate, and 211 (54%) with severe dry eye. In all three groups, screen/reading time generally doubled during the pandemic. Reduced work-related efficiency was noted by a considerable proportion of respondents (moderate dry eye: 51%, mild: 39%, and severe: 38%). Compared with respondents with mild dry eye, respondents with moderate dry eye were considerably more likely to note worsening symptoms: eye pain (OR = 2.57, 95% CI 1.22-5.41), headache from eye symptoms (OR = 2.34, 95% CI 1.11-4.90), and difficulty concentrating because of eye symptoms (OR = 2.79, 95% CI 1.37-5.66). Respondents with moderate dry eye with Sjögren's syndrome were most likely to note these. Respondents with severe dry eye were more likely than respondents with mild dry eye to report losing access to dry eye-related treatments (OR = 2.62, 95% CI 1.36-5.03)., Conclusions: The COVID-19 pandemic-related eye strain may be impacting symptoms, performance, and ultimately employment, especially for those with moderate dry eye. This may be compounding the already-high dry eye-related societal burden., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Objective: To define the association between oral and systemic manifestations of Sjögren syndrome (SS) and quality of life (QOL)., Methods: We analyzed a cross-sectional survey conducted by the Sjögren's Foundation in 2016, with 2961 eligible responses. We defined oral symptom and sign exposures as parotid gland swelling, dry mouth, mouth ulcers/sores, oral candidiasis, trouble speaking, choking or dysphagia, sialolithiasis or gland infection, and dental caries. Systemic exposures included interstitial lung disease, purpura/petechiae/cryoglobulinemia, vasculitis, neuropathy, leukopenia, interstitial nephritis, renal tubular acidosis, autoimmune hepatitis, primary biliary cholangitis, or lymphoma. Outcomes included SS-specific QOL questions generated by SS experts and patients., Results: Using multivariable regression models adjusted for age, sex, race, and employment, we observed that mouth ulcers or sores, trouble speaking, and dysphagia were associated with poor quality of life. The following oral aspects had the greatest effect on the following QOL areas: (1) mouth ulcers/sores on the challenge and burden of living with SS (OR 4.26, 95% CI 2.89-6.28); (2) trouble speaking on memory and concentration (OR 4.24, 95% CI 3.28-5.48); and (3) dysphagia on functional interference (OR 4.25, 95% CI 3.13-5.79). In contrast, systemic manifestations were associated with QOL to a lesser extent or not at all., Conclusion: Oral manifestations of SS, particularly mouth ulcers or sores, trouble speaking, and dysphagia, were strongly associated with worse QOL. Further study and targeted treatment of these oral manifestations provides the opportunity to improve quality of life in patients with SS., (Copyright © 2021 by the Journal of Rheumatology.)

Objective: To evaluate how ocular, oral, and bodily neuropathic pain symptoms, which characterize small fiber neuropathies, are associated with Sjögren's syndrome (SS) classification based on the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) criteria., Methods: Participants enrolled in the Sjögren's International Collaborative Clinical Alliance (SICCA) registry had ocular, rheumatologic, oral, and labial salivary gland (LSG) biopsy examinations, blood and saliva samples collected, and completed questionnaires at baseline. We used mixed effects modeling with age, country, gender, and depression being fixed effects and study site, a random effect, to determine if neuropathic pain indicators (assessed via questionnaires) were associated with being classified as SS., Results: A total of 3,514 participants were enrolled into SICCA, with 1,541 (52.9%) meeting the 2016 ACR/EULAR classification criteria for SS. There was a negative association between being classified as SS and experiencing bodily neuropathic pain features of needle-like pain, prickling/tingling sensation, ocular neuropathic pain of constant burning, and constant light sensitivity, and having a presumptive diagnosis of neuropathic oral pain., Conclusions: We found that those classified as SS had lower scores/reports of painful neuropathies compared with those classified as non-SS. Non-SS patients with dry eye disease or symptoms could benefit from pain assessment as they may experience painful small-fiber neuropathies (SFNs). Pain questionnaires may help identify pain associated with SFNs in patients with SS and non-SS dry eye. Future studies would be helpful to correlate self-reports of pain to objective measures of SFNs in those with SS, non-SS dry eye, and healthy controls., (© 2021 World Institute of Pain.)

Purpose: To report occurrence of cicatrizing conjunctivitis as an extraglandular ocular manifestation of primary Sjögren's syndrome (SS)., Methods: Medical charts of all patients with SS evaluated at two tertiary ophthalmological referral centers were reviewed. Patients who demonstrated clinical findings of cicatrizing conjunctivitis were included in this review. Patient and disease-related data including ocular complications, therapies and outcomes were collected., Results: Eight patients with a diagnosisis of SS were noted to have cicatrizing conjunctivitis findings over a period of 11 years (between 2009 and 2020). Mean age of patients was 79. All patients had a negative immunoreactant deposition in conjunctival biopsy. Mean follow-up time was 6 years (range, 18-197 months). Three patients had progression of conjunctival scarring. Worsening of vision occurred in 4 patients due to corneal complications, including ulceration, perforation and scarring., Conclusions: SS is an under-recognized etiology of severe progressive cicatrizing conjunctivitis that can lead to ocular morbidity and loss of vision without appropriate management., (Copyright © 2020 Elsevier Inc.

Purpose: To compare the burden related to dry eye with systemic symptoms of Sjögren syndrome; to estimate the burden related to ocular treatments; and to compare the impact of dry eye and extraocular manifestations of Sjögren syndrome on various aspects of patient life., Design: Cross-sectional study., Methods: We conducted a postal survey of adult patients with a history of physician-diagnosed Sjögren syndrome., Results: The survey was completed by 2,961 patients (mean age 65.1 years, standard deviation 11.7 years), most of whom were women (96%) and white (94%). Forty-one patients younger than 18 years of age were excluded. More than half (53%) experienced severe dry eye (ie, dry eye daily/almost daily with major impact on their life). Corresponding proportions for dry mouth and fatigue were 48% and 45%, respectively. Almost all patients (97%) had used nonprescription eye drops/artificial tears/ointments. Compared with patients who did not experience dry eye, those who experienced significant dry eye (ie, daily/almost daily dry eye) more often agreed that living with Sjögren syndrome made every day a challenge (adjusted odds ratio [OR] 3.81, 95% confidence interval [CI] 2.49 to 5.86) and added a significant emotional burden (adjusted OR 2.22, 95% CI 1.49 to 3.31). Adjusted ORs for the impact of dry eye were generally lower than those for fatigue, but were similar to dry mouth and considerably higher than use of systemic treatments for serious manifestations of the disease and diagnosis of lymphoma., Conclusions: Sjögren-related dry eye is more burdensome than systemic manifestations of the disease. While fatigue has the greatest impact on patient life, the impact of dry eye is comparable to that of other systemic manifestations., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Purpose: To report the significance of extraglandular ocular involvement and long-term systemic morbidity and mortality in primary Sjögren's Syndrome (SS)., Methods: This retrospective, longitudinal cohort study included consecutive patients with primary SS evaluated at a tertiary referral center. An electronic chart review was performed and all available data were extracted from clinic visits between October 1999 and March 2019. The primary outcome measures included occurrence of extraglandular ocular manifestations of SS, serological markers, prevalence of malignancy, and incidence of death., Results: One hundred and twenty-six SS patients with minimum 3 years of follow-up (median 9.6, range 3.0-15.9 years, total of 1,235 patient-years) were included. Of those, 10 patients with inflammatory keratolysis or scleritis had 2.3 times greater likelihood of death compared to the rest of the cohort (OR = 2.3, 95% confidence interval [CI] 0.5 to 4.0, p = 0.01) due to SS related complications. The lifetime prevalence of any malignancy in the entire cohort was 15.5%. The most common hematologic malignancy was non-Hodgkin's lymphoma (4.8%) and the most common solid malignancy was breast cancer (6.0%). Men SS patients were more likely to have a history of or concurrent malignancy compared to women (30.0% versus 13.7%, p = 0.16) and double the mortality (OR = 2.1, 95% CI 0.09 to 1.4, p = 0.04), independent of malignancy., Conclusions: SS patients with serious ocular manifestations, particularly men, may be at greater risk for mortality due to SS complications.

Purpose: To evaluate the ocular signs and tests for keratoconjunctivitis sicca (KCS) in the absence of a gold standard., Methods: Cross-sectional study of participants from the Sjögren's International Collaborative Clinical Alliance (SICCA) registry. Participants had oral/ocular/rheumatologic examinations, blood/saliva samples collected, and salivary gland biopsy. Latent class analysis (LCA) identified clusters of patients based on 3 to 4 predictor variables relating to signs or tests of KCS. The resulting model-based "gold standard" classification formed the basis for estimated sensitivity and specificity associated with these predictors., Results: A total of 3514 participants were enrolled into SICCA, with 52.9% classified as SS. LCA revealed a best-fit model with 2 groups. For the gold standard-positive group, an abnormal tear breakup time, ocular staining score (OSS), and Schirmer I had a sensitivity of 99.5%, 91.0%, and 47.4%, respectively. For the gold standard-negative group, an abnormal tear breakup time, OSS, and Schirmer I had a specificity of 32.0%, 84.0%, and 88.5%, respectively. OSS components (fluorescein and lissamine staining), exhibited a sensitivity of 82.6% and 90.5%, respectively, in the gold standard-positive group, whereas these signs in the gold standard-negative group had a specificity of 88.8% and 73.0%, respectively., Conclusions: OSS and its components (fluorescein and lissamine staining) differentiated 2 groups from each other better than other KCS parameters and had relatively high sensitivity and specificity.
