Ocular manifestations of juvenile Sjögren's disease.

PURPOSE OF REVIEW: This review aims to enhance understanding of juvenile Sjögren's disease (jSjD) by exploring diagnostic criteria, ocular clinical features, ancillary ophthalmic testing, and management strategies specific to this rare pediatric condition. RECENT FINDINGS: Unlike adults, children with jSjD often present with recurrent parotitis and extra-glandular symptoms before developing sicca symptoms. Adult SjD classification criteria do not consider pediatric-specific symptoms and physiological differences. Underutilization of diagnostic tests such as the ocular staining score (OSS) and Schirmer I may result in an incomplete understanding of the prevalence of keratoconjunctivitis sicca in jSjD. SUMMARY: Timely referral to an ophthalmologist can address perceived feasibility issues with respect to ocular features in jSjD. Management of keratoconjunctivitis sicca in jSjD includes improving ocular surface lubrication and decreasing inflammation. Recognition of pediatric-specific clinical features and development of universally accepted jSjD classification criteria will allow for better identification of potential participants for future jSjD studies.

Outcomes of Uveitic Macular Edema in the First-line Antimetabolites as Steroid-Sparing Treatment Uveitis Trial.

PURPOSE: To evaluate the outcomes of uveitic macular edema at 6 and 12 months in patients treated with methotrexate or mycophenolate mofetil. DESIGN: Subanalysis of a block-randomized, observer-masked, multicenter clinical trial. PARTICIPANTS: Patients were enrolled in the First-line Antimetabolites as Steroid-sparing Treatment (FAST) Uveitis Trial between August 2013 and August 2017. METHODS: Patients were randomized to oral methotrexate 25 mg weekly or mycophenolate mofetil 1.5 g twice daily for 12 months, along with a corticosteroid taper. In addition to standardized clinical examination, all patients underwent spectral-domain OCT imaging at each visit. At the 6-month primary end point, patients who achieved treatment success continued the same treatment for a subsequent 6 months, and treatment failures switched to the other treatment group. MAIN OUTCOME MEASURES: Prespecified 6-month primary outcome and 12-month outcomes of central subfield thickness and visual acuity. RESULTS: Of 216 patients in the FAST Trial, 42 eyes (30 patients) in the methotrexate group and 55 eyes (41 patients) in the mycophenolate group had uveitic macular edema. Baseline median central subfield thickness was 359 µm and 342 µm in the methotrexate and mycophenolate groups, respectively. At 12 months, for those who stayed on the same treatment, macular thickness decreased from baseline by 30.5 µm (interquartile range [IQR], -132.3 to 4.0) and 54 µm (IQR, -95.5 to -4.5) in the methotrexate and mycophenolate groups, respectively (P = 0.73). In patients who switched treatment at 6 months, macular thickness decreased from baseline by 12.5 µm (IQR, -32.3 to -0.5) and 50 µm (IQR, -181.0 to -10.0) in the methotrexate and mycophenolate groups, respectively (P = 0.34). At 12 months, 7 of 19 eyes (37%) on methotrexate had resolution of macular edema compared with 15 of 25 eyes (60%) on mycophenolate (P = 0.10). For those who switched treatments, 8 of 17 eyes (47%) on methotrexate and 6 of 11 eyes (55%) on mycophenolate had resolution of macular edema (P = 0.92). CONCLUSIONS: Treatment with methotrexate or mycophenolate mofetil for uveitic macular edema results in similar improvements in macular thickness at 6 and 12 months. At 12 months, approximately half of eyes in each antimetabolite group still had persistent macular edema.

Preliminary Screening Questionnaire for Sjögren's Syndrome in the Rheumatology Setting.

OBJECTIVE: Sjögren's syndrome (SS) is frequently undetected or misdiagnosed as other rheumatologic diseases. We aimed to develop an SS screening questionnaire for the rheumatology practice. METHODS: We developed the Sjögren's Syndrome Screening Questionnaire (SSSQ) via secondary analysis of data from 974 participants referred by rheumatologists to the Sjögren's International Collaborative Clinical Alliance (SICCA) study. Participants answered 88 questions regarding symptoms, medical history, and demographics. They underwent ocular, dental, and serologic tests and were classified as SS or non-SS using the 2016 American College of Rheumatology/European League Against Rheumatism classification criteria. We conducted univariate and multivariate logistic regression to identify questions most discriminative of SS, from which we derived an individual's likelihood of SS ("SSSQ score"). RESULTS: Five questions were significantly discriminative of SS in the multivariate analysis (p < 0.05): (1) Can you eat a cracker without drinking a fluid/liquid? (no: odds ratio [OR], 1.39; 95% confidence interval [CI], 1.06-1.82]); (2) How would you describe your dental and oral health in general? (fair/poor: OR, 1.68; 95% CI, 1.04-2.75); (3) During the last week, have you experienced tearing? (none of the time: OR, 2.26; 95% CI, 1.23-4.34); (4) Are you able to produce tears? (no: OR, 1.62; 95% CI, 1.12-2.37); and (5) Do you currently smoke cigarettes? (no: OR, 2.83; 95% CI, 1.69-4.91). SSSQ score ≥7 (possible range, 0-11) distinguishes SS from non-SS patients with 64% sensitivity and 58% specificity (area under receiver operating characteristic curve, 0.65). CONCLUSIONS: The SSSQ is a simple 5-item questionnaire designed to screen for SS in clinical practice, with a potential impact to reduce delays in diagnosis.

Health- and Vision-Related Quality of Life in a Randomized Controlled Trial Comparing Methotrexate and Mycophenolate Mofetil for Uveitis.

PURPOSE: To evaluate changes in health-related and vision-related quality of life (VRQoL) among patients with noninfectious uveitis who were treated with antimetabolites. DESIGN: Secondary analysis of a randomized controlled trial. PARTICIPANTS: Patients with noninfectious uveitis from India, the United States, Australia, Saudi Arabia, and Mexico. METHODS: From 2013 through 2017, 216 participants were randomized to receive 25 mg weekly oral methotrexate or 1.5 g twice daily oral mycophenolate mofetil. Median changes in quality of life (QoL) were measured using Wilcoxon signed-rank tests, and differences between treatment groups were measured using linear mixed models, adjusting for baseline QoL score, age, gender, and site. Among Indian patients, VRQoL scores from a general scale (the National Eye Institute Visual Function Questionnaire [NEI-VFQ]) and a culturally specific scale (the Indian Visual Function Questionnaire [IND-VFQ]) were compared using Pearson correlation tests. MAIN OUTCOME MEASURES: Vision-related QoL (NEI-VFQ and IND-VFQ) and health-related QoL (HRQoL; physical component score [PCS] and mental component score [MCS] of the Medical Outcomes Study 36-Item Short Form Survey [SF-36v2]) were measured at baseline, the primary end point (6 months or treatment failure before 6 months), and the secondary end point (12 months or treatment failure between 6 and 12 months). RESULTS: Among 193 participants who reached the primary end point, VRQoL increased from baseline by a median of 12.0 points (interquartile range [IQR], 1.0-26.1, NEI-VFQ scale), physical HRQoL increased by a median of 3.6 points (IQR, -1.4 to 14.9, PCS SF-36v2), and mental HRQoL increased by a median of 3.0 points (IQR, -3.7 to 11.9, MCS SF-36v2). These improvements in NEI-VFQ, SF-36v2 PCS, and SF-36v2 MCS scores all were significant (P < 0.01). The linear mixed models showed that QoL did not differ between treatment groups for each QoL assessment (NEI-VFQ, IND-VFQ, PCS SF-36v2, and MCS SF-36v2; P > 0.05 for all). The NEI-VFQ and IND-VFQ scores for Indian participants were correlated highly at baseline and the primary and secondary end points (correlation coefficients, 0.87, 0.80, and 0.90, respectively). CONCLUSIONS: Among patients treated with methotrexate or mycophenolate mofetil for uveitis, VRQoL and HRQoL improved significantly over the course of 1 year and did not differ by treatment allocation. These findings suggest that antimetabolites could improve overall patient well-being and daily functioning.

Neuropathic Pain in the Eyes, Body, and Mouth: Insights from the Sjögren's International Collaborative Clinical Alliance.

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.

Primary vitreoretinal lymphoma: empowering our clinical suspicion.

PURPOSE OF REVIEW: Vitreoretinal lymphoma (VRL) is well known as a masquerade syndrome. However, delays in diagnosis are common particularly because of the small volume of tissue that is used for investigative studies. We outline the current diagnostic tests available to clinicians and provide a glimpse of possible future novel diagnostics. RECENT FINDINGS: The use of spectral domain ocular coherence tomography to identify subretinal lesions has proven to be a reliable ally to clinicians. Nevertheless, the diagnostic gold standard remains cytology, which requires a skilled pathologist. Molecular tests, including MYD88 polymerase chain reaction testing has further refined our diagnostic capabilities. Metagenomic deep sequencing is a newer molecular test that offers the ability to identify any mutation associated with lymphoma development and may offer more sensitive testing in the future. SUMMARY: Clinicians have developed a strong acumen for suspecting VRL based upon clinical features, which can further be supported by a variety of imaging modalities. Delays in diagnosis continue to occur particularly because of the small volume of ocular fluid available for testing and because current tests offer a biased approach in terms of limited scope of detecting a specific mutation or cytopathologic feature(s). Newer molecular techniques feature an expanded scope of detecting any mutation associated with lymphomatous development.

Effect of Corticosteroid-Sparing Treatment With Mycophenolate Mofetil vs Methotrexate on Inflammation in Patients With Uveitis: A Randomized Clinical Trial.

Importance: Methotrexate and mycophenolate mofetil are commonly used immunomodulatory therapies for achieving corticosteroid-sparing control of noninfectious uveitis, but there is uncertainty about which drug is more effective. Objective: To compare the effect of methotrexate and mycophenolate for achieving corticosteroid-sparing control of noninfectious intermediate uveitis, posterior uveitis, and panuveitis. Design, Setting, and Participants: The First-line Antimetabolites as Steroid-sparing Treatment (FAST) uveitis trial screened 265 adults with noninfectious uveitis requiring corticosteroid-sparing immunosuppressive therapy from 9 referral eye centers in India, the United States, Australia, Saudi Arabia, and Mexico between August 22, 2013, and August 16, 2017. Follow-up ended on August 20, 2018. Interventions: Patients were randomized to receive oral methotrexate, 25 mg weekly (n = 107), or oral mycophenolate mofetil, 3 g daily (n = 109). Main Outcomes and Measures: The primary outcome was treatment success at 6 months, which was defined as having control of inflammation in both eyes, no more than 7.5 mg prednisone daily and less than or equal to 2 drops of prednisolone acetate 1%, and no treatment failure due to safety or intolerability. Patients underwent follow-up to 12 months while receiving the same treatment or switched to the other antimetabolite, depending on their 6-month outcome. Results: Among 216 patients who were randomized (median age, 38 years; 135 (62.5%) women), 194 (89.8%) completed follow-up through 6 months. Treatment success occurred in 64 (66.7%) patients in the methotrexate group vs 56 (57.1%) in the mycophenolate group (difference, 9.5% [95% CI, -5.3% to 21.8%]; odds ratio [OR], 1.50 [95% CI, 0.81 to 2.81]; P = .20). Among patients with posterior uveitis or panuveitis, treatment success was achieved in 58 (74.4%) in the methotrexate group vs 42 (55.3%) in the mycophenolate group (difference, 19.1% [95% CI, 3.6% to 30.6%]; OR, 2.35 [95% CI, 1.16 to 4.90]; P = .02); whereas among patients with intermediate uveitis treatment success occurred in 6 (33.3%) in the methotrexate group vs 14 (63.6%) in the mycophenolate group (difference, -30.3% [95% CI, -51.6% to 1.1%]; OR, 0.29 [95% CI, 0.08 to 1.05]; P = .07; P for interaction = .004). Elevated liver enzymes were the most common nonserious laboratory adverse event, occurring in 14 patients (13.0%) in the methotrexate group and 8 patients (7.4%) in the mycophenolate group. Conclusions and Relevance: Among adults with noninfectious uveitis, the use of mycophenolate mofetil compared with methotrexate as first-line corticosteroid-sparing treatment did not result in superior control of inflammation. Further research is needed to determine if either drug is more effective based on the anatomical subtype of uveitis. Trial Registration: ClinicalTrials.gov Identifier: NCT01829295.

Ocular manifestations of cytomegalovirus in immunocompetent hosts.

PURPOSE OF REVIEW: This review highlights recent studies that have increasingly implicated cytomegalovirus (CMV) as a significant cause of keratouveitis and retinitis in immunocompetent hosts. RECENT FINDINGS: Molecular testing has identified that CMV infection is frequently present in cases of Posner-Schlossman and Fuchs, keratouveitis syndromes previously presumed to be idiopathic conditions. Ocular hypertension and endothelial cell loss are important complications of CMV keratouveitis and are likely mediated by viral invasion of the trabecular meshwork and corneal endothelium. Topical ganciclovir is a well tolerated, effective, and economical therapy. CMV retinitis is possible in the absence of HIV/AIDS. SUMMARY: CMV has long been considered an innocuous infection in the general population, though recent studies have found otherwise. Intraocular reactivation, replication, and invasion of the trabecular meshwork and endothelium lead to recurrent bouts of ocular hypertension and endothelial cell loss, the complications of which may be tempered with initiation of antivirals. Topical ganciclovir is a promising therapy that needs investigation. CMV retinitis, an entity previously believed isolated to the severely immunosuppressed population, has been reported on numerous occasions in presumably immunocompetent individuals, particularly following local steroid injections. Further studies may elucidate the pathogenesis of CMV in immunocompetent populations.

Ocular cicatricial pemphigoid.

PURPOSE OF REVIEW: This review offers recommendations for monitoring disease status in ocular cicatricial pemphigoid as well therapeutic options including local and systemic therapies. RECENT FINDINGS: A negative biopsy on direct immunofluorescence does not preclude a diagnosis of OCP. If a patient's cicatrization is active and/or progressive, systemic immunosuppression should be commenced. SUMMARY: OCP is a chronic systemic autoimmune disease that requires systemic immunosuppression.

Ocular Signs and Testing Most Compatible with Sarcoidosis-Associated Uveitis: A Latent Class Analysis.

Purpose: This study aims to explore the potential subgroups of sarcoidosis-associated uveitis (SAU) within a multicenter cohort of uveitis participants. Design: Cross-sectional study. Participants: A cohort of 826 uveitis patients from a uveitis registry from 19 clinical centers in 12 countries between January 2011 and April 2015. Methods: We employed a latent class analysis (LCA) incorporating recommended tests and clinical signs from the revised International Workshop on Ocular Sarcoidosis (IWOS) to identify potential SAU subgroups within the multicenter uveitis cohort. Additionally, we assessed the performance of the individual tests and clinical signs in classifying the potential subclasses. Main Outcome Measures: Latent subtypes of SAU. Results: Among 826 participants included in this analysis, the 2-class LCA model provided a best fit, with the lowest Bayesian information criteria of 7218.7 and an entropy of 0.715. One class, consisting of 548 participants, represented the non-SAU, whereas the second class, comprised of 278 participants, was most representative of SAU. Snowballs/string of pearls vitreous opacities had the best test performance for classification, followed by bilaterality and bilateral hilar lymphadenopathy (BHL). The combination of 4 tests with the highest classification importance, including snowballs/string of pearls vitreous opacities, periphlebitis and/or macroaneurysm, bilaterality, and BHL, demonstrated a sensitivity of 84.8% and a specificity of 95.4% in classifying the SAU subtypes. In the exploratory analysis of the 3-class LCA model, which had comparable fit indices as the 2-class model, we identified a candidate non-SAU subtype, candidate SAU subtype with pulmonary involvement, and a candidate SAU with less pulmonary involvement. Conclusions: Latent class modeling, incorporating tests and clinical signs from the revised IWOS criteria, effectively identified a subset of participants with clinical features indicative of SAU. Though the sensitivity of individual ocular signs or tests was not perfect, using a combination of tests provided a satisfactory performance in classifying the SAU subclasses identified by the 2-class LCA model. Notably, the classes identified by the 3-class LCA model, including a non-SAU subtype, an SAU subtype with pulmonary involvement, and an SAU subtype with less pulmonary involvement, may have potential implication for clinical practice, and hence should be validated in further research.

Sjögren's Versus Non-Sjögren's Ocular Features: Similar Symptoms, But Significantly Worse Signs.

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.

Risk factors for corneal abrasions in Nepal: a community-based study.

BACKGROUND: South Asia is experiencing rapid urbanization, which may be changing the risk factor profile for ocular trauma. The objective of this study was to compare risk factors for traumatic corneal abrasions in rural versus urban Nepal, and to assess if any risk factors were associated with a poor outcome. METHODS: In a prospective, cross-sectional, community-based study performed as part of a cluster-randomized trial, community health workers from Nepal were trained to diagnose and treat traumatic corneal abrasions. Participants with an abrasion were invited to complete a risk factor survey. The main exposure variable was the object of eye injury, stratified by rural-urban residence. The main outcome measure was a lack of corneal healing after a three-day course of antimicrobials. RESULTS: Of 3657 participants diagnosed with a corneal abrasion, 2265 completed a survey. Eye trauma occurred most frequently during agricultural activities. The most common object of injury was vegetative matter, accounting for approximately 40% of injuries in rural, peri-urban, and urban communities. Wood injuries were more common in rural communities (24%) compared with urban or peri-urban communities (13%). Eye injury from an animal was more likely to result in a non-healing corneal abrasion after 3 days of treatment compared with other types of trauma (prevalence ratio 2.59, 95%CI 1.16-5.76). CONCLUSIONS: Health promotion activities for prevention of corneal ulcers in Nepal should focus on agricultural trauma in both rural and urban areas. Community members experiencing eye trauma from an animal may benefit from early referral to an eye clinic.

Association between Quality of Life and Visual Acuity in a Randomized Clinical Trial of Patients with Uveitis Taking Antimetabolites.

PURPOSE: To evaluate how changes in visual acuity are associated with changes in quality of life (QoL) among patients with non-infectious uveitis taking antimetabolites. METHODS: This secondary analysis of the multicenter First-line Antimetabolites as Steroid-sparing Treatment (FAST) Uveitis Trial involves 216 participants randomized to methotrexate or mycophenolate mofetil. Vision-related (NEI-VFQ and IND-VFQ) and health-related (PCS and MCS SF-36v2) QoL and visual acuity were measured at baseline and 6-month primary endpoint. RESULTS: Visual acuity was significantly associated and correlated with all QoL measures (Spearman correlation coefficients = 0.5, 0.5, 0.3, and 0.4 for NEI-VFQ, IND-VFQ, SF-36v2 MCS and PCS, respectively). All observed changes in QoL met or exceeded the minimal clinically important difference definition on each scale. Treatment group was not significantly associated with any QoL measure. CONCLUSION: By adding insight beyond visual acuity, QoL provides a more comprehensive picture of the patient experience during uveitis treatment.Abbreviations and Acronyms: QoL = quality of life; VR-QoL = vision-related quality of life; HR-QoL = health-related quality of life; FAST = First-line Antimetabolites as Corticosteroid Sparing Treatment; NEI-VFQ = National Eye Institute Visual Functioning Questionnaire; IND-VFQ = Indian Visual Functioning Questionnaire; SF-36v2 = Medical Outcomes Study 36-Item Short Form Survey; PCS = physical component score; MCS = mental component score; 95% CI = 95% confidence interval; MCID = minimal clinically important difference.

Outcomes in Patients with Vogt-Koyanagi-Harada Disease from the First-line Antimetabolites for Steroid-sparing Treatment Uveitis Trial.

PURPOSE: To compare the effectiveness of methotrexate (MTX) and mycophenolate mofetil (MMF) in achieving corticosteroid-sparing control of uveitis in patients with Vogt-Koyanagi-Harada (VKH) disease. METHODS: A subanalysis of patients with VKH from the First-line Antimetabolites as Steroid-sparing Treatment (FAST) Uveitis Trial, a randomized, observer-masked, comparative effectiveness trial, with comparisons by treatment (MTX versus MMF) and disease stage (acute versus chronic). Individuals with noninfectious uveitis were placed on a standardized corticosteroid taper and block randomized 1:1 to either 25mg weekly oral MTX or 1.5g twice daily oral MMF. The primary outcome was treatment success defined by corticosteroid-sparing control of uveitis at 6 months. Additional outcomes included change in best spectacle-corrected visual acuity (BSCVA), retinal central subfield thickness (CST), and resolution of serous retinal detachment (SRD). RESULTS: Ninety-three out of 216 enrolled patients had VKH; 49 patients were randomized to MTX and 44 to MMF, of which 85 patients (46 on MTX, 39 on MMF) contributed to the primary outcome. There was no significant difference in treatment success by antimetabolite (80.4% for MTX compared to 64.1% for MMF; P=.12) or in BSCVA improvement (P=.78). Methotrexate was superior to MMF in reducing CST (P=.003) and resolving SRD (P=.02). There was no significant difference in treatment success by disease stage (P=.25), but patients with acute VKH had greater improvement in BSCVA (P<.001) and reduction of CST (P=.02) than chronic VKH patients. CONCLUSIONS: MTX and MMF have comparable outcomes as corticosteroid-sparing immunosuppressive therapies for VKH. Visual acuity improvement was greater in acute vs chronic VKH. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT00182929.

Detection of Leptospirosis Genome from the Aqueous Humor of a Patient with Bilateral Uveitis.

BACKGROUND: Leptospira species are difficult to culture. Thus, when there is suspicion for an infectious etiology to uveitis, bacterial cultures may fail to identify Leptospira. We describe a case of leptospirosis-associated uveitis that evaded culture and molecular assays. DNA sequencing of the aqueous fluid showed the presence of Leptospira spp. METHODS: Retrospective case review of clinical and laboratory features of a patient with ocular leptospirosis is presented. RESULTS: DNA sequencing identified the genome of Leptospirosis spp. in the aqueous humor. CONCLUSION: Metagenomic sequencing, by virtue of its unbiased nature, can be a helpful adjunctive test when a strong clinical suspicion for intraocular infection persists despite negative routine culture and molecular assays.

Efficacy of the Fluocinolone Acetonide (Yutiq) Intravitreal Implant as Monotherapy for Uveitis.

PURPOSE: To evaluate the efficacy of the fluocinolone acetonide intravitreal implant (Yutiq) as monotherapy for uveitis. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients at a single academic health-care institution. METHODS: Medical record review of patients with non-infectious uveitis actively suppressed on an alternative anti-inflammatory regimen who received a fluocinolone acetonide implant. The primary outcome was continued control of inflammation based on clinical examination, optical coherence tomography, and fluorescein angiography. RESULTS: Thirteen patients (19 eyes) received an implant. Median follow-up was 6 months. Uveitis control was achieved in 14 eyes (74%), though three (21%) required a topical steroid after insertion. The remaining five eyes (26%) required additional intraocular treatments. CONCLUSION: The fluocinolone acetonide implant may not suffice as monotherapy for all patients with uveitis, but it may be effective as an adjunctive treatment. We propose a clinical workflow for the selection and treatment of patients who may benefit from it.

Prevalence of Epstein-Barr Virus in Patients with Intraocular Inflammation.

The relationship between Epstein-Barr virus (EBV) infection and uveitis is unclear. We conducted an observational cross-sectional study to determine the prevalence of EBV in uveitis and to describe the clinical features of EBV-positive uveitis cases. This study was carried out at the F.I. Proctor Foundation at the University of California, San Francisco. All patients with suspected infectious uveitis who underwent unbiased metagenomic deep sequencing (MDS) were included. Demographics, testing information, and clinical features were documented. Eleven out of 288 patients with suspected infectious uveitis had EBV detected by RNA-seq in intraocular fluid. The prevalence of EBV in uveitis in our study sample is 4%. Three out of 11 EBV-positive eyes (27%) were found to have biopsy-proven vitreoretinal lymphoma. Future studies are needed to determine if EBV may drive the development of vitreoretinal lymphoma and if its presence should heighten the suspicion of vitreoretinal lymphoma.

Central Corneal Subbasal Nerve Plexus Abnormalities in Sjögren Disease: A Pilot Study.

PURPOSE: Small-fiber neuropathy (SFN) is known to be associated with Sjögren disease (SjD), and in vivo corneal confocal microscopy can identify features compatible with SFN. Here, we performed a descriptive study to identify features of SFN of the corneal subbasal nerve plexus using in vivo confocal microscopy. METHODS: We recruited 10 participants from the Sjögren's International Collaborative Clinical Alliance (SICCA), 1 new participant (in an effort to expand the SICCA cohort), and 22 healthy controls. All participants underwent slit-lamp examination and in vivo confocal microscopy of the central corneal subbasal nerve plexus centered about the central whorl to create a 30-image montage. Each image was analyzed with automated software (ACCmetrics, Manchester, United Kingdom) to produce 7 nerve metrics. We performed t-tests and age-adjusted regressions to make comparisons of nerve metrics between participants with SjD and healthy controls. RESULTS: Most nerve metrics were significantly lower in participants with SjD compared with healthy controls. The mean corneal nerve fiber density was found to be 3.5 mm/mm 2 in participants with SjD compared with 10.6 mm/mm 2 in healthy controls (95% confidence interval, -8.4 to -0.93; P = 0.02). Within the 11 participants with SjD, 22 eyes were analyzed on confocal microscopy, and 16 of those eyes (from 9 individuals) did not have an identifiable central whorl. Within the 22 healthy controls, 22 eyes (right eye alone) were analyzed on confocal microscopy, and 21 of those eyes had an identifiable central whorl. CONCLUSIONS: SjD exhibits lower corneal nerve metrics compared with healthy controls. These findings suggest that features compatible with SFN can distinguish SjD from healthy controls and may serve as a potential novel biomarker in identifying SjD.
