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.

Abstract 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

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.

Purpose: To report the case of a patient who presents with multiple progressive ocular diseases who is diagnosed with concurrent primary Sjögren's syndrome and isolated ocular sarcoidosis. Observation: A 60-year-old woman was referred for dry eye disease, bilateral interstitial keratitis, anterior uveitis, and progressive glaucoma. There was clinical suspicion of an autoimmune etiology due to her ocular history, risk factors, and presentation. Thorough diagnostic testing revealed both primary Sjögren's syndrome and ocular sarcoidosis. After 2.5 years of systemic treatment and follow up, the patient currently remains stable. Conclusions and importance: Autoimmune disease may underlie those with progressive ocular disease with an unknown etiology. More than one autoimmune disease may be the cause of ocular findings, especially for patients with a complicated presentation. Proper awareness, clinical suspicion, and diagnosis of these diseases can greatly improve a patient's condition and prevent future ocular and systemic complications.

PurposeTo report the significance of extraglandular ocular involvement and long-term systemic morbidity and mortality in primary Sjögren's Syndrome (SS).MethodsThis 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.ResultsOne 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.ConclusionsSS patients with serious ocular manifestations, particularly men, may be at greater risk for mortality due to SS complications. The eye seems to be the barometer of systemic disease activity.

Background. Diagnostic criteria for Sjögren’s syndrome (SS) are continually being updated in pursuit of more precise and earlier diagnosis to prevent its complications. Owing to the high rate of false negative traditional serological markers, the need for better serological testing remains. Objective. To investigate the clinical significance of three recently discovered novel autoantibodies, anti-salivary gland protein 1 (SP1), anti-carbonic anhydrase 6 (CA6), and anti-parotid secretory protein (PSP), in a cohort of dry eye patients with suspected underlying inflammatory/autoimmune disease. Methods. Medical records of 136 patients with a primary diagnosis of dry eye who underwent laboratory testing between April 2014 and July 2017 were reviewed retrospectively. Data regarding demographic information, ocular and systemic symptoms, previous medical diagnoses, serological test results, and minor salivary gland biopsy results were collected. Dry eye evaluations included tear osmolarity, Schirmer test without anesthesia, conjunctival lissamine green staining, and corneal fluorescein staining in the order listed here. Results. Of the 136 patients, 9 (9/136, 6.6%) presented with a history of SS, and 9 additional patients (9/127, 7%) received a new diagnosis of SS as a result of evaluations. Fifty-six patients (56/136, 41%) tested positive for at least one of the novel autoantibodies. Fifty-four percent (6/11) of patients with primary SS who underwent the novel serological testing had a positive anti-PSP. Of those, 2 (2/11, 18%) had negative traditional serology and had to undergo minor salivary gland biopsy for definitive diagnosis. Anti-CA6 was associated with increased corneal and conjunctival staining after adjusting for age, sex, and other serologic markers (HR=1.5, 95% CI=1.20-1.97, and p=0.009 and HR=1.4, 95% CI=1.04-1.76, and p=0.02, respectively). Conclusions. This cross-sectional study demonstrated that anti-CA6 is seen in patients with severe aqueous-deficient dry eye. Whether these patients have an early stage of SS or a different type of autoimmune condition may be determined through longitudinal studies.

A 31-year-old male patient was admitted with the complaint of decreased vision in both eyes. He underwent multiple pars plana vitrectomy and silicone oil injection operations due to bilateral retina detachment after rocket projectile explosion in his hands at the age of 15. The right eye was pre-phthisical after choroidal hemorrhage that occurred during combined silicone oil extraction and penetrating keratoplasty. The aphakic and vitrectomized left eye had corneal conjunctivalisation of seven dials, deep and superficial stromal neovascularization and history of immunological graft rejection. As the estimated success rate for repeat penetrating keratoplasty was low, Boston type 1 keratoprosthesis surgery was performed. Postoperatively, visual acuity was 0.2 Snellen lines. Macular scar and optic nerve atrophy limited further visual gain. In this study, we aimed to review the current literature about Boston type keratoprosthesis surgery, which should be evaluated as an alternative when conventional penetrating keratoplasty success is deemed to be low.

ObjectiveThe 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.MethodsParticipants 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.ResultsA 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.ConclusionCompared 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.

ObjectiveTo 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.MethodsParticipants 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.ResultsA 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.ConclusionsWe 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.

PurposeTo develop a screening questionnaire to identify patients with dry eye with a high likelihood of having underlying Sjögren syndrome (SS).MethodsThis 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.ResultsFour 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).ConclusionsThis 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.

PurposeTo evaluate the ocular signs and tests for keratoconjunctivitis sicca (KCS) in the absence of a gold standard.MethodsCross-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.ResultsA 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.ConclusionsOSS 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.

PurposeTo identify a screening strategy for dry eye patients with a high likelihood of having Sjogren syndrome (SS) through the evaluation of the association of ocular surface tests with the extraocular signs used for the diagnosis of SS.DesignMulticenter cross-sectional study.MethodsThe Sjogren's International Clinical Collaborative Alliance (SICCA) registry enrolled 3514 participants with SS or possible SS from 9 international academic sites. Ocular surface evaluation included Schirmer I testing, tear breakup time (TBUT), and staining of the cornea (0-6 points) and conjunctiva (0-6 points). Multivariate logistic regression analysis was performed to identify predictive factors for (1) histopathologic changes on labial salivary gland (LSG) biopsies (positive = focus score of ≥1 focus/4 mm2) and (2) positive anti-SSA/B serology.ResultsThe adjusted odds of having a positive LSG biopsy were significantly higher among those with an abnormal Schirmer I test (adjusted OR = 1.26, 95% CI 1.05-1.51, P = .014) and positive conjunctival staining (for each additional unit of staining 1.46; 95% CI 1.39-1.53, P < .001) or corneal staining (for each additional unit of staining 1.14; 95% CI 1.08-1.21, P < .001). The odds of having a positive serology were significantly higher among those with an abnormal Schirmer I test (adjusted OR = 1.3; 95% CI 1.09-1.54, P = .004) and conjunctival staining (adjusted OR = 1.51; 95% CI 1.43-1.58, P < .001).ConclusionsIn addition to corneal staining, which was associated with a higher likelihood of having a positive LSG biopsy, conjunctival staining and abnormal Schirmer I testing are of critical importance to include when screening dry eye patients for possible SS, as they were associated with a higher likelihood of having a positive LSG biopsy and serology.

This retrospective analysis of pooled data from 2 clinical trials using cyclosporine 0.1% in the treatment of dry eye showed larger improvement in corneal staining, compared with vehicle, by day 15. 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.

PurposeTo determine the intra-observer and inter-observer reliability of a novel ocular staining score among trained ophthalmologists.DesignReliability analysis within a prospective, observational, multicenter cohort study.MethodsThose enrolled in the National Institutes of Health-funded Sjögren's International Collaborative Clinical Alliance (SICCA) who presented for follow-up at the University of California San Francisco, Aravind Eye Hospital, Johns Hopkins University, and the University of Pennsylvania were included. Study participants were graded using the ocular staining score by at least 2 masked SICCA-trained ophthalmologists. The primary outcome for this study was the intraclass correlation coefficient (ICC) for the total ocular staining score. ICCs were also calculated for tear break-up time (TBUT) and conjunctival and corneal staining.ResultsTotal ocular staining score had an ICC of 0.91 for the right eye (95% confidence interval [CI] 0.85-0.96) and 0.90 for the left eye (95% CI 0.83-0.97). Corneal staining (right eye 0.86, 95% CI 0.76-0.93, left eye 0.90, 95% CI 0.81-0.95) and conjunctival staining (right eye 0.87, 95% CI 0.80-0.93, left eye 0.85, 95% CI 0.75-0.93) demonstrated excellent agreement. The ICC for TBUT was slightly lower (right eye 0.77, 95% CI 0.64-0.89; left eye 0.81, 95% CI 0.68-0.90).ConclusionsPrevious studies have shown that the ocular staining score is correlated with other diagnostic components of Sjögren syndrome. In this study, we demonstrate high reliability in grading among trained ophthalmologists, completing the validation of this test.

Abstract Background The six-minute walk test (6MWT) is widely used to assess functional capacity and prognosis in patients with idiopathic pulmonary fibrosis (IPF). However, studies on oxygen saturation recovery after the 6MWT in patients with IPF are rare. In our study, we investigated the relationship between oxygen saturation recovery time and dyspnea, fatigue, quality of life, prognostic markers and pulmonary hypertension (PH). Methods In this cross-sectional study, IPF patients diagnosed according to current guidelines and followed up in our Interstitial Lung Disease Outpatient Clinic between 2021 and 2022 were included. Demographics, data from spirometry, diffusion capacity measurement, arterial blood gas analysis, transthoracic echocardiography and the 6MWT were recorded. The oxygen saturation recovery time, distance saturation product (DSP), gender-age-physiology (GAP) index and composite physiological index (CPI) scores were calculated. Dyspnea severity was assessed by the modified Medical Research Council (mMRC) and Dyspnoea-12 (D-12) scales, fatigue severity by the Multidimensional Fatigue Inventory (MFI-20) and quality of life by the St George’s Respiratory Questionnaire (SGRQ). Results Fifty IPF patients (34 men, 16 women, age: 66.8 ± 7.3 years) were included in the study. The mean FVC was 77.8 ± 19.3%, the DLCO was 52.9 ± 17.1%, the 6-minute walk distance (6MWD) was 385.7 ± 90.6 m, the GAP index was 3.5 ± 1.5, and the CPI was 43.7 ± 14.1. Oxygen saturation after the 6MWT reached pretest values at an average of 135.6 ± 73.5 s. The oxygen saturation recovery time was longer in patients with higher GAP index scores (Rs = 0.870, p

Introduction/Background Patients with atopic dermatitis (AD) have greater risk of conjunctivitis and other ocular surface disorders than the general population. In clinical trials of dupilumab in adult patients with moderate-to-severe AD, conjunctivitis and other ocular surface adverse events (AEs) were reported more frequently in patients who received dupilumab than in those who received placebo. Clinical features of ocular AEs in dupilumab-treated patients with AD are not well characterized, and there is a need for consensus on management approaches. Objectives To assess treatment and outcomes for conjunctivitis associated with dupilumab treatment for AD. Methods Treatment patterns and outcomes were assessed during a prospective observational study evaluating conjunctivitis in dupilumab-treated patients with AD (group 1) and a dupilumab-treated reference group of patients with AD without ocular symptoms (group 2). Patients were initially prescribed dupilumab by a dermatologist for treatment of AD. After at least 8 weeks, a patient was eligible to be referred to an ophthalmologist, who then determined final eligibility for the study. Dupilumab-treated patients with AD and conjunctivitis that had newly developed or significantly worsened (group 1) were followed for at least 24 weeks. A reference group of dupilumab-treated patients with AD without ocular symptoms (group 2) was evaluated at baseline visit with the ophthalmologist and Week 4. All ophthalmological treatments were at the discretion of the ophthalmologist, who also assessed conjunctivitis treatment effectiveness. Results A total of 49 patients were enrolled: 35 patients in Group 1 and 14 patients in Group 2. 3 patients in Group 2 who presented with active ocular inflammation at the initial visit were excluded from further analysis. 16 Group 1 patients (46%) and 7 Group 2 patients (64%) had a history of an ocular disorder prior to enrollment. Group 1 patients were diagnosed with AD at a younger age compared with group 2, with longer AD duration. More patients in group 1 reported history of facial AD lesions, including eyelid involvement, and history of AD facial lesions during flares. The most frequent ophthalmological diagnoses in Group 1 were non-infective conjunctivitis (46%), allergic conjunctivitis (26%) and keratoconjunctivitis (14%). The most prominent symptom was itching, followed by redness, grittiness/sandiness, swelling, tearing, burning, stinging, and light sensitivity. Corticosteroid (eye drops) were the most frequently prescribed treatment (n = 46) and their effectiveness was assessed by the ophthalmologist as excellent in 39.1% of uses and very good in 39.1%. Topical calcineurin inhibitors (either tacrolimus ointment or cyclosporin eye drops) were the next most frequently prescribed treatment (n = 31) and their effectiveness assessed as excellent in 45.2% of uses and very good in 12.9%. In participants who completed at least 24 weeks of observation, most events recovered/resolved (21/25 [84.0%]) or were resolving/recovering (3/25 [12.0%]); 1/25 [4.0%] participant had an event that was not recovered/resolved. No participants discontinued treatment with dupilumab. Conclusions Patients with AD treated with dupilumab with prolonged history of AD and facial and/or eyelid lesions may be more prone to developing ocular events. Both topical corticosteroids (eyedrops) and topical calcineurin inhibitors (eyedrops or ointment) resulted in resolution of ocular signs and symptoms and recovery in most patients, without dupilumab discontinuation.
