Comparisons of choroidal blood flow velocity between initial-onset acute uveitis associated with Vogt-Koyanagi-Harada disease and acute central serous chorioretinopathy

OBJECTIVES

Acute central serous chorioretinopathy (CSC) and Vogt-Koyanagi-Harada (VKH) disease in the acute uveitic phase are characterized by serous retinal detachment caused by dysfunction of the choroid. The aim of this study is to compare blood flow velocity and pulse waveform parameters in the choroid between these two diseases.

METHODS

In this study, 25 patients (50 eyes) with VKH disease, 21 patients (27 eyes) with CSC and 15 healthy controls (30 eyes) were studied. Laser speckle flowgraphy (LSFG) was performed at presentation.

RESULTS

Choroidal mean blur rate (MBR), representing blood flow velocity in choroidal vessels, was significantly lower in the eyes affected by VKH disease compared with the healthy control and CSC eyes. CSC eyes had a significantly higher MBR compared with healthy controls. Among the analyzed pulse waveform parameters, blow-out time (BOT), falling rate (FR) and flow acceleration index (FAI) changed significantly. BOT value was significantly lower in CSC eyes than in healthy control and VKH eyes. FR and FAI values were significantly lower in VKH eyes than in healthy control and CSC eyes. There was a strong positive correlation between MBR and FAI.

CONCLUSIONS

Our findings confirm different pathophysiology of these two diseases. Assessment of choroidal blood flow velocity and haemodynamics with LSFG provides useful information to differentiate acute CSC and initial-onset acute uveitis associated with VKH disease.

Clinical profile and evolution of patients with juvenile-onset Behçet's syndrome over a 25-year period: insights from the AIDA network

Behçet's syndrome (BS) represents an understudied topic in pediatrics: the main aims of our study were to characterize demographic and clinical features of a cohort of BS patients with juvenile-onset managed in three tertiary referral centers in Italy, evaluate their evolution in the long-term, and detect any potential differences with BS patients having an adult-onset. Medical records of 64 juvenile-onset and 332 adult-onset BS followed-up over a 2-year period were retrospectively analyzed and compared. Mean age ± SD of first symptom-appearance was 10.92 ± 4.34 years with a female-to-male ratio of 1.06:1. Mucocutaneous signs were the most frequent initial manifestations, followed by uveitis. Throughout the disease course, genital aphthae (76.56%) and pseudofolliculitis (40.63%) prevailed among the mucocutaneous signs, while major organ involvement was represented by gastrointestinal and ocular involvement (43.75 and 34.38%, respectively). No significant differences emerged for both mucocutaneous signs and specific major organ involvement between juvenile-onset and adult BS patients. After excluding nonspecific abdominal pain, juvenile-onset BS patients were less frequently characterized by the development of major organ involvement (p = 0.027). Logistic regression detected the juvenile-onset as a variable associated with reduced risk of long-term major organ involvement (OR 0.495 [0.263-0.932], p = 0.029). In our cohort, juvenile-onset BS resembled the clinical spectrum of adult-onset patients. Pediatric patients with a full-blown disease at onset showed a more frequent mucocutaneous involvement. In addition, patients with juvenile-onset seemed to develop less frequently major organ involvement and had an overall less severe disease course.

Immunopathophysiology and clinical impact of uveitis in inflammatory rheumatic diseases: An update

BACKGROUND

Uveitis is one of the most frequent ophthalmologic manifestations in rheumatology. Uveal inflammation can underlie a systemic inflammatory rheumatic disease (SIRD) in approximately 30% of cases with a significant burden on the quality of life since it represents a cause of blindness in up to 20% of cases in Western countries.

METHODS

In this review, we provide a comprehensive overview of the pathophysiology of uveitis associated with SIRDs. According to our literature survey on the epidemiology of uveitis among SIRDs, spondyloarthritides, Behçet's disease and sarcoidosis get the major impact.

RESULTS

In Behçet's uveitis, the key players are highly polarized Th1 and Th17 lymphocytes, natural killer T cells and γδ T cells. All contribute to a great destructive inflammatory environment with the most serious visual damage resulting from the involvement of the posterior segment of the eye. In contrast, spondyloarthritides-related uveitis derives from a complex interaction between genetic background and extra-ocular inflammatory mediators originating from enthesitis, arthritis, psoriatic lesions and microbiome pro-inflammatory alterations. In such conditions, the immune infiltration of CD4+ T cells, Th17 and natural killer cells along with pro-inflammatory cytokines, TNF-α among all, leads to intraocular inflammation. Lastly, granuloma formation represents the primary hallmark lesion in sarcoid uveitis. This suggests a profound link between the innate system that mainly recruits activated macrophages and adaptive system involving by Th1, Th17 and Th17.1 cells.

CONCLUSIONS

Awareness among rheumatologists of a potential severe ocular involvement generates new insights into targeted therapeutic approaches and personalized treatments for each patient.

Intravitreal Steroid Treatment for Uveitis Associated with Dabrafenib and Trametinib for Metastatic Cutaneous Melanoma

Purpose: To report a case of bilateral retinal inflammation under long-term therapy with dabrafenib/trametinib for metastatic cutaneous melanoma.Methods: Retrospective chart review.Results: A 59-year-old patient with metastatic cutaneous melanoma diagnosed in 2004 under treatment with dabrafenib/trametinib since 2014 presented to our department with intraretinal hemorrhage and extrafoveal macula edema on the right eye and optic disc swelling on the left eye. The patient did not report visual complaints. After cessation of dabrafenib/trametinib and subconjunctival and intravitreal corticosteroid injections, optic disc swelling on the left eye recovered after 6 months. The macula edema on the right eye was treated with one intravitreal anti-VEGF (vascular endothelial growth factor) injection after encroaching upon the fovea 10 months after initial presentation. The final visual acuity was 20/20 on both eyes.Conclusion: Even after years of treatment with low dose dabrafenib/trametinib, ocular toxicity can develop. Such cases can respond well to intravitreal corticosteroids.

Visual Dysfunction in Multiple Sclerosis and its Animal Model, Experimental Autoimmune Encephalomyelitis: a Review

Visual disabilities in central nervous system autoimmune diseases such as multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE), are important symptoms. Past studies have focused on neuro-inflammatory changes and demyelination in the white matter of the brain and spinal cord. In MS, neuro-inflammatory lesions have been diagnosed in the visual pathway; the lesions may perturb visual function. Similarly, neuropathological changes in the retina and optic nerves have been found in animals with chronic EAE. Although the retina and optic nerves are immunologically privileged sites via the blood-retina barrier and blood-brain barrier, respectively, inflammation can occur via other routes, such as the uvea (e.g., iris and choroid) and cerebrospinal fluid in the meninges. This review primarily addresses the direct involvement of the blood-retina barrier and the blood-brain barrier in the development of retinitis and optic neuritis in EAE models. Additional routes, including pro-inflammatory mediator-filled choroidal and subarachnoid spaces, are also discussed with respect to their roles in EAE-induced visual disability and as analogues of MS in humans.

Uveitis for the non-ophthalmologist

The uveitides are a heterogeneous group of diseases characterized by inflammation inside the eye. The uveitides are classified as infectious or non-infectious. The non-infectious uveitides, which are presumed to be immune mediated, can be further divided into those that are associated with a known systemic disease and those that are eye limited,-ie, not associated with a systemic disease. The ophthalmologist identifies the specific uveitic entity by medical history, clinical examination, and ocular imaging, as well as supplemental laboratory testing, if indicated. Treatment of the infectious uveitides is tailored to the particular infectious organism and may include regional and/or systemic medication. First line treatment for non-infectious uveitides is corticosteroids that can be administered topically, as regional injections or surgical implants, or systemically. Systemic immunosuppressive therapy is used in patients with severe disease who cannot tolerate corticosteroids, require chronic corticosteroids at >7.5 mg/day prednisone, or in whom the disease is known to respond better to immunosuppression. Management of many of these diseases is optimized by coordination between the ophthalmologist and rheumatologist or internist.

The Effect of Adalimumab in Korean Patients with Refractory Noninfectious Uveitis

We sought to analyze the efficacy of adalimumab in active noninfectious uveitis, and evaluate its efficacy and safety for the management of refractory noninfectious uveitis in Korean patients. A retrospective observational study was conducted. A total of 23 eyes of 14 Korean patients with noninfectious uveitis refractory to conventional treatment, including corticosteroid and immunosuppressive agents, were treated with adalimumab between December 2017 and February 2020. The primary outcomes were vitreous haziness grades, anterior chamber cell grades, and central macular thickness measured prior to injection and at 1, 3, 6, and 12 months after the first adalimumab injection. Among the 23 eyes, 14 eyes (60.9%) were diagnosed with panuveitis and 9 eyes (39.1%) with posterior uveitis [mean follow-up period: 22.3 months (7-27)]. The most common etiologic diagnoses requiring adalimumab injection were Behçet's disease (9 eyes, 39.1%), followed by undifferentiated inflammation (6 eyes, 26.1%), Vogt-Koyanagi-Harada disease (3 eyes, 13.0%), psoriasis (2 eyes, 8.7%), serpiginous chorioretinopathy (2 eyes, 8.7%), and systemic lupus erythematosus (1 eye, 4.3%). At the 1-year follow-up after the first injection, anterior chamber cell grade decreased from 0.5±0.4 to 0.3±0.4, and vitreous haziness grade decreased from 1.1±1.1 to 0.3±0.5 (p<0.05). Central macular thickness improved from 347.2±98.1 μm to 264.3±61.1 μm (p<0.05). Adalimumab injection in patients with refractory noninfectious uveitis decreased the anterior chamber cell grade, vitreous haziness grade, and central macular thickness with no severe side effect. Overall, adalimumab injection may, therefore, be an effective and relatively safe treatment modality for noninfectious uveitis in Korean patients.

Quantitative Analysis of the Choriocapillaris in Uveitis Using En Face Swept-Source Optical Coherence Tomography Angiography

PURPOSE

To perform a quantitative analysis of choriocapillaris (CC) flow deficits (FDs) in patients with uveitis.

DESIGN

Retrospective cross-sectional study.

METHODS

Swept-source optical coherence tomography based angiography (SS-OCTA) macular volume scans (3 × 3 mm and 6 × 6 mm) were obtained using the Plex Elite 9000. En face CC images were generated and analyzed using an automated FD identification algorithm. Three quantitative metrics were determined for each eye: FD number (FDN), mean FD size (MFDS), and FD density (FDD). Quantitative metrics were compared between uveitis and control eyes. The uveitis cohort was further subdivided by the presence or absence of choroidal involvement, and quantitative metrics were compared between subgroups and normal control subjects.

RESULTS

A total of 38 eyes from 38 control subjects and 73 eyes from 73 uveitis subjects were included in this study. Eyes with uveitis have significantly larger CC MFDS (3- × 3-mm scans; P < .0001; 6- × 6-mm scans; P < .0001) and higher FDD (P = .0002; P = .0076, respectively) compared to control eyes. Additional analysis determined that these differences were due to the choroidal disease subgroup, which demonstrates significantly larger MFDS (3 × 3 = 1,108 μm²; 6 × 6 = 1,104 μm²) compared to both normal control eyes (752 μm²; P < .0001; 802 μm²; P < .0001, respectively) and uveitis patients without choroidal involvement (785 μm²; P < .0001; 821 μm²; P < .0001, respectively). No significant differences were found between the quantitative metrics of control subjects and patients without choroidal involvement.

CONCLUSIONS

Automated quantification of CC can identify pathological FDs and provide quantitative metrics describing such lesions in patients with uveitis. Posterior uveitis patients have significantly larger CC FDs than patients with other forms of uveitis.

Importance of pediatric rheumatologists and transitional care for juvenile idiopathic arthritis-associated uveitis: a retrospective series of 9 cases

BACKGROUND

Juvenile idiopathic arthritis-associated uveitis (JIA-U) is a serious condition associated with the risk of blindness. However, pediatric rheumatologists rarely encounter cases of blindness, because most patients reach adulthood during the course of follow-up before blindness occurs. Here, we report the progress of 9 patients with JIA-U, including 2 patients who became blind after the transition period. We aimed to highlight the importance of the role of pediatric rheumatologists and transitional care in preventing blindness associated with JIA-U.

CASE PRESENTATION

We conducted a retrospective analysis of the case records of 9 JIA-U patients (1 male, 8 female; median age 16.8 years, range 5.5-19.8 years). All patients presented with oligo-juvenile idiopathic arthritis (oligo-JIA) (one presented with extended oligo-JIA); the median age of uveitis onset was 5.0 years (range 3.0-13.0 years), and the onset of uveitis preceded the onset of arthritis in 2 patients. The median disease duration was 12.5 years (range 3.5-24.7 years); 4 patients had anti-nuclear antibody (ANA) positivity (≧1:160) (all with a homogeneous and speckled-pattern subtype). All patients were negative for rheumatoid factor. Eight patients received methotrexate, 7 patients received one or more biologic drugs (etanercept, infliximab, adalimumab, and golimumab), and 6 patients required ophthalmic surgery at an early age (≦ 18 years). Two patients developed blindness after the transition period. Medical examination by pediatric rheumatologists and use of biologics had been delayed in both patients. One patient developed depression after transition and interrupted her own treatment.

CONCLUSIONS

The reason for blindness in the 2 patients was thought to be the delay in the commencement of treatment and failure to provide transitional care. Inflammation is difficult to control in JIA-U even with appropriate treatment. Pediatric rheumatologists must be informed about the risk of JIA-U blindness, especially after transition. To ensure a good prognosis, the specialized treatment with the involvement of pediatric rheumatologists is necessary early on, and consideration for transitional medicine is essential. Therefore, this report reaffirms the importance of planned transitional care that has been advocated for globally.

[Clinical features of patients with Behcet's uveitis]

Objective: To characterize the clinical features of patients with Behcet's uveitis. Methods: Retrospective case series study. Medical records of patients who were diagnosed as Behcet's uveitis in Peking Union Medical College Hospital between January 1998 and November 2015 were retrospectively reviewed. Information about the clinical manifestation, complication, best corrected visual acuity (logarithm of the minimum angle of resolution) and medication was collected. The correlation of visual acuity and the disease course, as well as inflammation relapse times before and after biological agents applied was analyzed. Chi square test and Wilcoxon signed-rank test were applied for statistical analysis. Results: A total of 132 patients (233 eyes) with Behcet's uveitis were included, among which 104 (78.8%) were male and 28 (21.2%) were female, with statistically significant difference (χ(2)=43.76, P<0.01). The average age at the onset of uveitis was (28.9±8.7) years, with most patients at 21-40 years (102 cases, 77.3%). Oral aphthae (132 cases, 100.0%) were the most frequent extraocular manifestations, followed by dermatologic lesions (103 cases, 78.0%), genital ulcers (90 cases, 68.2%), arthritis (44 cases, 33.3%) and positive pathergy test (39 cases, 29.5%). Ocular involvement was bilateral in 76.5% (101 cases) of the patients, and panuveitis was the most common type (110 cases, 83.3%). Complications were seen in 80.7% (188/233) of the eyes, with cataract (58.8%, 137/233) and macular edema (59.1%, 114/193) being the most common anterior and posterior segment complications, respectively. At the eighth year of uveitis, best corrected visual acuity decreased to less than 0.3 in 20.9% (9/43) of the eyes, and more than 1.0 in 39.5% (17/43) of the eyes. A combination of glucocorticoids and immune modulators remained the first line therapy (97.0%, 128/132) for Behcet's uveitis. For 16 refractory cases, an addition of biological agents significantly reduced the inflammation relapse [0.5 (0.0, 1.5) times per year vs. 4.0 (1.0, 5.5) times per year, Z=-2.81, P=0.005]. Conclusions: Behcet's uveitis mainly affects working-age males and manifests as bilateral panuveitis. Complications are commonly seen in uveitic eyes. Patients' visual acuity is significantly impaired. A combination of glucocorticoids and immune modulators is effective for most patients, but for refractory cases, an addition of biological agents provides better effects.

A C-terminal peptide from type I interferon protects the retina in a mouse model of autoimmune uveitis

Experimental autoimmune uveitis (EAU) in rodents recapitulates many features of the disease in humans and has served as a useful tool for the development of therapeutics. A peptide from C-terminus of interferon α1, conjugated to palmitoyl-lysine for cell penetration, denoted as IFNα-C, was tested for its anti-inflammatory properties in ARPE-19 cells, followed by testing in a mouse model of EAU. Treatment with IFNα-C and evaluation by RT-qPCR showed the induction of anti-inflammatory cytokines and chemokine. Inflammatory markers induced by treatment with TNFα were suppressed when IFNα-C was simultaneously present. TNF-α mediated induction of NF-κB and signaling by IL-17A were attenuated by IFNα-C. Differentiated ARPE-19 cells were treated with TNFα in the presence or absence IFNα-C and analyzed by immmunhistochemistry. IFNα-C protected against the disruption integrity of tight junction proteins. Similarly, loss of transepithelial resistance caused by TNFα was prevented by IFNα-C. B10.RIII mice were immunized with a peptide from interphotoreceptor binding protein (IRBP) and treated by gavage with IFNα-C. Development of uveitis was monitored by histology, fundoscopy, SD-OCT, and ERG. Treatment with IFNα-C prevented uveitis in mice immunized with the IRBP peptide. Splenocytes isolated from mice with ongoing EAU exhibited antigen-specific T cell proliferation that was inhibited in the presence of IFNα-C. IFNα-C peptide exhibits anti-inflammatory properties and protects mice against damage to retinal structure and function suggesting that it has therapeutic potential for the treatment of autoimmune uveitis.

Comparison Between Methotrexate and Mycophenolate Mofetil Monotherapy for the Control of Noninfectious Ocular Inflammatory Diseases

PURPOSE

To compare mycophenolate mofetil (MMF) to methotrexate (MTX) as corticosteroid-sparing therapy for ocular inflammatory diseases.

DESIGN

Retrospective analysis of cohort study data.

METHODS

Participants were identified from the Systemic Immunosuppressive Therapy for Eye Diseases Cohort Study. Demographic and clinical characteristics were obtained via medical record review. The study included 352 patients who were taking single-agent immunosuppression with MTX or MMF at 4 tertiary uveitis clinics. Marginal structural models (MSM)-derived statistical weighting created a virtual population with covariates and censoring patterns balanced across alternative treatments. With this methodological approach, the results estimate what would have happened had none of the patients stopped their treatment. Survival analysis with stabilized MSM-derived weights simulated a clinical trial comparing MMF vs MTX for noninfectious inflammatory eye disorders. The primary outcome was complete control of inflammation on prednisone ≤10 mg/day, sustained for ≥30 days.

RESULTS

The time to success was shorter (more favorable) for MMF than MTX (hazard ratio = 0.68, 95% confidence interval: 0.46-0.99). Adjusting for covariates, the proportion achieving success was higher at every point in time for MMF than MTX from 2 to 8 months, then converges at 9 months. The onset of corticosteroid-sparing success took more than 3 months for most patients in both groups. Outcomes of treatment (MMF vs MTX) were similar across all anatomic sites of inflammation. The incidence of stopping therapy for toxicity was similar in both groups.

CONCLUSIONS

Our results suggest that, on average, MMF may be faster than MTX in achieving corticosteroid-sparing success in ocular inflammatory diseases.

Time Trade-off Utility Values in Noninfectious Uveitis

PURPOSE

To investigate time trade-off (TTO) utility values in patients with noninfectious uveitis and determine whether patient demographics and clinical characteristics are associated with utility scores.

DESIGN

Time trade-off utility analysis.

METHODS

Setting: A tertiary care uveitis center in San Francisco, California, USA.

PATIENT POPULATION

One hundred and four consecutive adults with noninfectious uveitis, enrolled between November 2016 and February 2017.

MAIN OUTCOME MEASURES

TTO utility values, as collected by an interviewer-guided survey. Information regarding general health, ocular symptoms, and religion was also collected and medical record review was conducted to record anatomic location of uveitis, disease activity, visual acuity, and treatments. Multivariable regression analysis with backward selection was used to identify variables associated with TTO values.

RESULTS

Median TTO score was 0.975 (interquartile range [IQR]: 0.8-1.0), corresponding to trading a median 1.28 years of remaining life for healthy eyes (IQR: 0-6.29). Regression analysis revealed that worse eye visual acuity, >6 months of oral corticosteroid use, and current antidepressant use were associated with lower TTO scores (P = .008, P = .006, P = .008, respectively), controlling for age and sex. In particular, patients who had been taking oral corticosteroids for more than 6 months, regardless of dose, were 10.5 times more likely to trade 20% or more years of remaining life (TTO ≤0.8) than patients not taking oral corticosteroids (95% confidence interval: 2.3, 48.1; P = .002).

CONCLUSIONS

Patients with noninfectious uveitis had measurable, though modest, reductions in quality of life, as assessed by TTO, and these decreases were significantly associated with visual acuity in the worse eye and long-term oral corticosteroid use.

Pattern and diagnostic evaluation of systemic autoinflammatory diseases other than familial Mediterranean fever among Arab children: a multicenter study from the Pediatric Rheumatology Arab Group (PRAG)

To define the spectrum and phenotypic characteristics of systemic autoinflammatory diseases (SAIDs) other than familial Mediterranean fever (FMF) in Arab children and to delineate diagnostic evaluation. Data retrospectively collected on patients with clinical and/or genetically proven SAIDs other than FMF at 10 tertiary Arab pediatric rheumatology clinics from 1990 to 2018. The collected data comprised the clinical findings and diagnostic evaluation including genetic testing, the provided treatment and the accrual damage related to SAIDs. A total of 144 patients (93 female) with a median age at onset of 2.5 (range 0.1-12) years were enrolled. The initial diagnosis was inaccurate in 49.3%. Consanguinity rate among parents was 74.6%. The median time-to-diagnosis for all SAIDs was 2.5 (range 0.1-10) years. There were 104 patients (72.2%) with a confirmed diagnosis and 40 patients with suspected SAIDs. Seventy-two had monogenic and 66 patients with multifactorial SAIDs while six patients had undifferentiated SAIDs. The most frequent monogenic SAIDs were LACC1 mediated monogenic disorders (n = 23) followed by CAPS (12), TRAPS (12), HIDS (12), and Majeed's syndrome (6). The most frequent multifactorial SAIDs was CRMO (34), followed by PFAPA (18), and early onset sarcoidosis (EOS) (14). Genetic analysis was performed in 69 patients; 50 patients had genetically confirmed disease. Corticosteroid used for 93 patients while biologic agents for 96 patients. Overall, growth failure was the most frequent accrual damage (36%), followed by cognitive impairment (13%). There were three deaths because of infection. This study shows a heterogenous spectrum of SAIDs with a high number of genetically confirmed monogenic diseases; notably, LACC1 associated diseases. Hopefully, this work will be the first step for a prospective registry for SAIDs in Arab countries.

Dexamethasone Intravitreal Implant Injection in Eyes with Comorbid Hypotony

PURPOSE

To evaluate outcomes in patients with hypotony treated with intravitreal dexamethasone implant (Ozurdex).

DESIGN

Retrospective cohort study.

PARTICIPANTS

Thirteen patients (15 eyes) that received a total of 99 dexamethasone implant injections on occasions at which the intraocular pressure was low, meeting the definition of statistical hypotony.

METHODS

The medical records of 13 patients (15 consecutive eyes) receiving 1 or more intravitreal dexamethasone implants between December 2014 and April 2017 were reviewed retrospectively. Hypotony was defined as intraocular pressure less than 6.5 mmHg. The indications for intravitreal dexamethasone implant injection were intermediate or posterior uveitis (86.7%), diabetic macular edema (13.3%), and/or cystoid macular edema (6.7%).

MAIN OUTCOME MEASURES

The primary outcome measures were safety outcomes and best visual acuity within 6 months of the final intravitreal dexamethasone implant injection in a hypotonous eye.

RESULTS

In 15 eyes (13 patients), 99 injections were administered to eyes under circumstances of hypotony. Uveitic cystoid macular edema or diabetic macular edema was reduced after treatment in all cases. No complications were noted during the injection procedure. Three complications were noted in 2 patients after injection. Pseudophakodonesis and mild vitreous hemorrhage immediately after injection were noted in 1 patient, and a case of delayed-onset vitreous hemorrhage with pigment release was noted in another. All 3 complications resolved without intervention. The primary end point of this study-mean visual acuity-was stable over the follow-up period. In patients with hypotony whose intraocular pressure normalized during the follow-up period, this was attributable to management of glaucoma surgery-related complications rather than an effect of the intravitreal dexamethasone implant.

CONCLUSIONS

Intravitreal dexamethasone implant injection is a reasonable treatment option for patients with comorbid hypotony in whom clinical findings warrant treatment with a sustained-delivery intravitreal steroid implant. Further studies, including imaging of zonules before and after intravitreal dexamethasone implant injection in a hypotonous eye, could help define risks to intraocular lens stability with this procedure.

Evaluating the Impact of Uveitis on Visual Field Progression Using Large-Scale Real-World Data

PURPOSE

To compare rates of visual field (VF) loss in uveitis patients with glaucoma against patients with primary open-angle glaucoma (POAG) and explore the association between intraocular pressure (IOP) and rate of VF loss.

DESIGN

Retrospective cohort study.

METHODS

Anonymized VFs and IOP measurements extracted from the electronic medical records of 5 regionally different glaucoma clinics in England. A total of 205 eyes with diagnosis of uveitis plus glaucoma were compared with 4600 eyes with POAG only. Minimum inclusion criteria were ≥4 visits within a 4-year window. Relative risk (RR) of being a "rapid progressor" (mean deviation [MD] loss ≥1.5 dB/year) was calculated. A mixed-effects model (MEM) and a pointwise VF progression analysis of pattern deviation were used to confirm differences between the groups. Longitudinal IOP mean, range, and variability were compared with rate of VF progression.

RESULTS

Median (interquartile range) baseline MD in the uveitis and POAG groups was -3.8 (-8.7, -1.5) dB and -3.1 (-6.6, -1.2) dB, respectively. The uveitis and POAG groups had 23 of 205 (11%) and 331 of 4600 (7%) "rapidly progressing" eyes, respectively. Age-adjusted RR for "rapid progression" in uveitic vs POAG eyes was 1.9 (95% confidence interval: 1.8-2.0). The MEM confirmed that uveitic eyes (-0.49 dB/year) showed higher rates of VF progression than the POAG group (-0.37 dB/year; P < .01). IOP range and variability were higher in the "rapidly progressing" uveitic eyes.

CONCLUSIONS

Our analysis suggests that VF loss occurs faster in glaucoma patients with uveitis than those without uveitis. The risk of progressing rapidly in glaucoma with uveitis is almost double than in those without uveitis. Early identification of "rapid progressors" may enable targeted intervention to preserve visual function in this high-risk group.

Adalimumab in Juvenile Idiopathic Arthritis-Associated Uveitis: 5-Year Follow-up of the Bristol Participants of the SYCAMORE Trial

PURPOSE

To determine longer-term outcomes of participants enrolled from a single center in the SYCAMORE trial, a randomized placebo-controlled trial of adalimumab vs placebo in children with juvenile idiopathic arthritis-associated uveitis (JIA-U) uncontrolled on methotrexate.

DESIGN

Retrospective interventional case series.

METHODS

Medical records of all 28 SYCAMORE participants recruited at the Bristol Eye Hospital were reviewed at approximately 3-monthly intervals up to 5 years from the trial randomization date. Uveitis activity, treatment course, visual outcomes, ocular complications, and adverse events were recorded. Data are presented using summary statistics.

RESULTS

Following withdrawal of the investigational medicinal product (IMP), 25 of the 28 participants were started on adalimumab for active JIA-U. Of the 12 participants in the active treatment arm of the SYCAMORE study, 11 (92%) were restarted on adalimumab after withdrawal of the IMP for active JIA-U (median time to flare 188 days [range 42-413 days). Two participants stopped adalimumab for uncontrolled JIA-U. One participant had a reduction in vision to 0.3 owing to cataract. Mean visual acuity for the remaining 27 participants was -0.04 (right eye) and -0.05 (left eye).

CONCLUSIONS

Drug-induced remission of JIA-U did not persist when adalimumab was withdrawn after 1-2 years of treatment. Adalimumab was well tolerated and visual acuity outcomes were excellent.

Long-term probability of intraocular pressure elevation with the intravitreal dexamethasone implant in the real-world

PURPOSE

To evaluate the long-term cumulative probability of intraocular pressure (IOP) elevation with the intravitreal dexamethasone implant (IDI) when used to treat different indications: diabetic macular edema, uveitis, retinal vein occlusion.

METHODS

705 IDI injections (429 eyes) were assessed and Kaplan-Meier graphs were generated to assess: the probability of different levels of IOP elevation (IOP≥21, ≥25 or ≥35 mmHg), IOP change ≥10 mmHg, initiation of IOP-lowering treatment, glaucoma surgery, IOP change with repeat injections and IOP elevation in eyes with glaucoma and ocular hypertension (OHT).

RESULTS

The cumulative probability of IOP ≥21, ≥25 and ≥35 mmHg was 50%-60%, 25%-30% and 6%-7% at 12-24 months, respectively. The probability of initiating IOP-lowering medication was 31%-54% at 12-24 months. Glaucoma and OHT eyes had a higher probability of mild IOP elevation (≥21 mmHg, 65.1%, 75% and 57.8%, p = 0.01), yet a similar moderate (≥25 mmHg, 22.3%, 28% and 30.2%, p = 0.91) and severe elevation of IOP (≥35 mmHg, 3.7%, 7.1% and 4%, p = 0.71) as normal eyes. Glaucoma surgery was required in only 0.9% cases (4/429). At baseline, 8.8% of the treated eyes had glaucoma, 6.7% OHT and 16.9% were already on IOP-lowering medication.

CONCLUSIONS

In the long-term (24 months), IOP elevation is common, generally mild (30% IOP, ≥25 mmHg) and well-tolerated, resolving with topical treatment (54%) and rarely requiring surgery (0.9%).

Age-related differences in the clinical features of ocular sarcoidosis

The distribution of age at diagnosis in ocular sarcoidosis has shifted towards the older age groups in developed countries. In systemic sarcoidosis, age-related differences in the clinical presentation, which reflect the therapeutic strategies, was reported. We retrospectively compared 100 consecutive patients from April 2010 to March 2016 who were initially diagnosed with ocular sarcoidosis by International Workshop on Ocular Sarcoidosis criteria. They were classified into elder (>65 years: 50 patients) and younger (≤65 years: 50 patients) groups by the age at diagnosis of uveitis associated with sarcoidosis. All patients received ophthalmic examination to assess the presence of seven intraocular signs and 4 laboratory parameters. Significantly fewer ocular signs (2.8 ± 1.5 and 3.6 ± 1.5; P = 0.0034) and abnormal laboratory results (1.5 ± 1.2 and 2.0 ± 1.2; P = 0.023) were detected in the elder group than in the younger group; statistical differences were found between the groups regarding the frequencies of mutton-fat keratic precipitates (40% and 64%; P = 0.012), vitreous opacities (60% and 78%; P = 0.0059), bilateral inflammation (64% and 80%; P = 0.012), and bilateral hilar lymphadenopathy between the groups (52% and 78%; P < 0.001). Multiple linear regression analysis showed negative correlations between age and number of detected ocular signs (r = −0.36, P < 0.001) and laboratory results (r = −0.20, P = 0.023). The characteristic ocular signs and abnormal laboratory results had a lower frequency in the elder patients compared with the younger patients. Probable or possible ocular sarcoidosis by the international criteria should increase with increased life expectancy in developed countries.

Golimumab in refractory uveitis associated to juvenile idiopathic arthritis: multicentre study of 7 cases and literature review

OBJECTIVES

To assess the efficacy of golimumab (GLM), a fully humanised anti-TNF-α monoclonal antibody, in refractory juvenile idiopathic arthritis (JIA)-associated uveitis.

METHODS

This was a multicentre study of JIA-associated uveitis refractory to standard synthetic immunosuppressive drugs and in most cases to other anti-TNF-α agents. Results were expressed as mean±standard deviation or as median (range or interquartile range). The Wilcoxon signed-rank test was used to compare continuous variables. A literature review of the efficacy of GLM in uveitis related to JIA was also conducted.

RESULTS

We studied 7 patients (5 females; mean age 21.7±7.5 years; 13 affected eyes). Uveitis was bilateral in 6. Cystoid macular oedema (CME) occurred in 3 patients (5 eyes). Besides corticosteroids and synthetic immunosuppressive drugs, patients had received before GLM a median of 2 biologic agents (range 0-3) including adalimumab (n=6), etanercept (n=2), infliximab (n=3) and abatacept (n=2). GLM dose was 50 mg/sc every 4 weeks. After 6 months of therapy the number of anterior chamber cells decreased from 1 [0.25-1.5] to 0 [0-0.5] (p=0.02) and optical coherence tomography (in patients with CME) from 313.6±77.05 to 261.4±75.1 μm (p=0.03). The best-corrected visual acuity increased from 0.5 to 0.62 (p=0.018). Complete remission of uveitis was achieved in 4 of 7 patients after 16.8±11.4 months of follow-up. However, 2 of the seven patients had to be switched to tocilizumab due to inefficacy. Local erythema at the injection site was observed in 2.

CONCLUSIONS

GLM may be considered in the management of refractory JIA-related uveitis.

Different composition of intraocular immune mediators in Posner-Schlossman-Syndrome and Fuchs' Uveitis

Posner-Schlossman-Syndrome (PSS) is clinically characterized by acute, recurrent, mild, unilateral uveitis anterior accompanied by elevated intraocular pressure (IOP). Fuchs´ Uveitis (FU) is a chronic, low-grade-inflammatory disorder, involving anterior uvea and vitreous. The clinical findings show remarkable similarities as well as differences. In our study, we determine the composition of immune mediators in aqueous humor of patients with PSS and FU and evaluate if immune mediators play a crucial role in specific viral intraocular inflammation and IOP rises. Aqueous humor samples from 81 uveitis patients (= eyes) presenting with either PSS or FU were collected at one time point. Local intraocular antibody synthesis to rubella virus was confirmed in 65 patients, whereas 16 were tested positively for human cytomegalovirus. Thirteen patients with PSS and 10 patients with FU were treated with glaucoma medications. Additionally, 11 cataract patients acted as control group. Immune mediator concentrations were measured by Bio-Plex Pro assay. We observed in both PSS (IFN-γ: 174.9 pg/mL; TNF-α: 25.1 pg/mL) and FU (IFN-γ: 25.4 pg/mL; TNF-α: 27.2 pg/mL) groups a significantly increased level of T-helper 1 immune mediators compared to controls (IFN-γ, TNF-α: 0 pg/mL) [median]. Notably, PSS patients (IL-1RA: 73.4 pg/mL; IL-8: 199.4 pg/mL; IL-10: 33.4 pg/mL; IP-10: 126350 pg/mL) showed a stronger and more active ocular inflammatory response, than FU patients (IL-1RA: 4.3 pg/mL; IL-8: 72.4 pg/mL; IL-10: 1.6 pg/mL; IP-10: 57400 pg/mL). Furthermore, a negative correlation between mediators and IOP was seen in the PSS group, potentially caused by acetazolamide-treatment. Our findings show that immune mediators play a crucial role in specific viral intraocular inflammation and influence IOP levels. Remarkable similarities but also significant differences of immune mediator concentrations are apparent in PSS compared to FU. High concentrations of IL-1RA, IL-8, IL-10, and IP-10 correlate with active inflammation in PSS, while FU may trigger chronic inflammation. Our data also substantiated a very similar composition of cytokines in those patients from the PSS group suffering from ocular hypertension and thus offers a potential explanation model for a negative correlation between mediators and IOP.

A Glimpse into Uveitis in the Aging Eye: Pathophysiology, Clinical Presentation and Treatment Considerations

Uveitis describes a group of inflammatory conditions of the eye that have various underlying causes and clinical presentations. Susceptibilities to uveitis in the elderly may be attributed to age-related risk factors such as immunosenescence, increased immunological inflammatory mediators, and autoimmunity. Overall, anterior uveitis is more common than posterior and panuveitis in the general population and also in the elderly. Some causes of uveitis in the elderly are herpes simplex virus, ocular ischemic syndrome, sarcoidosis, and central nervous system lymphoma, and these will be discussed in detail herein. Eye care professionals need to consider the wide differential for uveitis, obtain the appropriate history, conduct a detailed clinical examination, and tailor management to the clinical presentation and underlying cause of disease. The challenges of polypharmacy and nonadherence in the elderly impact patient outcomes and must be taken into consideration when considering treatment.

Color Doppler Imaging in Uveitis

PURPOSE

To evaluate the vascular hemodynamic changes that can be detected with color Doppler imaging (CDI) in diagnosis, differential diagnosis and prognosis of uveitis with different etiologies including Behçet's disease.

METHODS

Four groups consisting of healthy volunteers, uveitis patients with different etiologies and Behçet's disease patients with and without ocular involvement were examined by CDI. Central retinal artery (CRA), posterior ciliary artery (PCA), ophthalmic artery (OA) and central retinal vein (CRV) flow velocities and vascular resistances were measured prospectively by a radiologist blinded to the presence and etiology of uveitis.

RESULTS

The peak systolic and end-diastolic velocities in CRA and PCA in Behçet's disease with ocular involvement were significantly lower than all other groups (p < 0.001). Peak systolic and end-diastolic velocities in CRA were lower than the control group in Behçet's disease patients without ocular involvement (p < 0.001) but there were no differences in PCA and OA flow velocity (p > 0.05). In the uveitis group, CRA and CRV flow velocities were significantly lower than in the control group (p < 0.001).

CONCLUSIONS

According to our results, uveitis in Behçet's disease is associated with significant reductions of CRA and PCA flow velocities when compared with other types of uveitis and healthy subjects. In cases without ocular involvement, CRA flow velocities were lower than the control group, but there were no real differences in the PCA and OA values. This suggests that vasculitic involvement of PCA is more specific to Behçet's disease and occurs later in the course of the disease. The results also suggest that it may be possible to detect and follow hemodynamic changes in Behçet's disease with CDI before clinical findings of ocular involvement become evident.

Diagnostic Function of 3D Optical Coherence Tomography Images in Diagnosis of Vogt-Koyanagi-Harada Disease at Acute Uveitis Stage

BACKGROUND This study analyzed the macular 3D-OCT images of Vogt-Koyanagi-Harada disease (VKH) in uveitis, explored the characteristics of 3D-OCT images of the macular region of VKH, and assessed which characteristics contribute most to VKH diagnosis. MATERIAL AND METHODS The 3D-OCT examination of 25 cases of VKH was performed on the macular area, and the image characteristics were analyzed. RESULTS Our study included a total of 50 eyes from 25 cases of VKH patients, 10 males and 15 females, aged 17 to 64 years, mean (39.44±11.60) years old. According to OCT B-scan images, 49 (98%) eyes had ERD, 49 (98%) eyes had nerve retinal edema, 36 (72%) eyes had endometrium-like structure (including cysts), 5 (10%) eyes had RPE folds, 35 (70%) eyes had changes in the internal septum, 49 (98%) eyes had RPE monolayer structure outside the ERD region. In ILM-RPE thickness, 49 (98%) eyes had retinal irregular thickening and 31 (62%) eyes had radial stripe changes. In ILM contour figure, 50 eyes (100%) showed exceptional uplift, 5 (10%) eyes had small focal uplift for PED on the RPE surface, and 48 (96%) eyes had wavy ups and downs. CONCLUSIONS In OCT B-scan imaging, the ERT, retinal edema of the retina, and the RPE monolayer structure outside the range are most likely to occur in VKH. The ILM-RPE thickness chart in 3D reconstruction showed irregular thickening of the retina. The ILM contour graph showed abnormal uplift, and RPE surface wavy ups and downs in VKH most likely to occur.

Immunosuppression for the Uveitides

The uveitides are a collection of more than 30 diseases characterized by intraocular inflammation. Many cases of juvenile idiopathic arthritis-associated uveitis, many cases of intermediate uveitis, and most cases of posterior and panuveitides requiring treatment are treated with corticosteroids and immunosuppression. Disease-specific, time-updated modeling of clinical data for several uveitides suggests superior prevention of ocular complications and visual outcomes with immunosuppression. These studies also suggest that oral corticosteroids at doses low enough for safe long-term therapy (i.e., <7.5 mg/day) are ineffective, implying that immunosuppression should be part of the initial regimen. The Multicenter Uveitis Steroid Treatment (MUST) Trial and Follow-up Study was a randomized comparative effectiveness trial comparing systemic therapy with oral corticosteroids and immunosuppression with regional corticosteroid treatment. It demonstrated that, when used properly, oral corticosteroids and immunosuppression can be given safely for up to 7 years with no evident increased risk of systemic side effects compared with regional corticosteroid therapy, except for greater antibiotic use for infections. The Systemic Treatment for Eye Diseases (SITE) Cohort Study suggested long-term safety for this approach, when the immunosuppressive agents were antimetabolites or calcineurin inhibitors. Thus, oral corticosteroids and immunosuppression may be a preferred initial therapy for many noninfectious, intermediate, posterior, and panuveitides. Nonalkylating-agent immunosuppression has a low rate of sustained, drug-free remissions, <10%/year. Nonalkylating-agent immunosuppression for >3 years with control of the inflammation for >2 years is associated with a decreased risk of relapse after discontinuing immunosuppression. Alkylating agents can induce sustained drug-free remissions but likely increase the lifetime risk of cancer. Biologics, which target specific cytokines and pathways, hold promise for the future. Monoclonal antibodies directed against tumor necrosis factor (TNF)-α have been studied most often, and one, adalimumab, is U.S. Food and Drug Administration approved for the treatment of noninfectious, intermediate, posterior, and panuveitides.

Guidance on Noncorticosteroid Systemic Immunomodulatory Therapy in Noninfectious Uveitis: Fundamentals Of Care for UveitiS (FOCUS) Initiative

TOPIC

An international, expert-led consensus initiative to develop systematic, evidence-based recommendations for the treatment of noninfectious uveitis in the era of biologics.

CLINICAL RELEVANCE

The availability of biologic agents for the treatment of human eye disease has altered practice patterns for the management of noninfectious uveitis. Current guidelines are insufficient to assure optimal use of noncorticosteroid systemic immunomodulatory agents.

METHODS

An international expert steering committee comprising 9 uveitis specialists (including both ophthalmologists and rheumatologists) identified clinical questions and, together with 6 bibliographic fellows trained in uveitis, conducted a Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol systematic review of the literature (English language studies from January 1996 through June 2016; Medline [OVID], the Central Cochrane library, EMBASE, CINAHL, SCOPUS, BIOSIS, and Web of Science). Publications included randomized controlled trials, prospective and retrospective studies with sufficient follow-up, case series with 15 cases or more, peer-reviewed articles, and hand-searched conference abstracts from key conferences. The proposed statements were circulated among 130 international uveitis experts for review. A total of 44 globally representative group members met in late 2016 to refine these guidelines using a modified Delphi technique and assigned Oxford levels of evidence.

RESULTS

In total, 10 questions were addressed resulting in 21 evidence-based guidance statements covering the following topics: when to start noncorticosteroid immunomodulatory therapy, including both biologic and nonbiologic agents; what data to collect before treatment; when to modify or withdraw treatment; how to select agents based on individual efficacy and safety profiles; and evidence in specific uveitic conditions. Shared decision-making, communication among providers and safety monitoring also were addressed as part of the recommendations. Pharmacoeconomic considerations were not addressed.

CONCLUSIONS

Consensus guidelines were developed based on published literature, expert opinion, and practical experience to bridge the gap between clinical needs and medical evidence to support the treatment of patients with noninfectious uveitis with noncorticosteroid immunomodulatory agents.

The eye involvement in monogenic autoinflammatory diseases: literature review and update

Monogenic autoinflammatory diseases (AIDs) are rare entities characterised by improper activation of the innate immune system. This in turn determines recurrent episodes of systemic inflammation characterised by fever, which is variously combined with a wide range of inflammatory manifestations involving the skin, joints, serous membranes, gastrointestinal tract, and central nervous system. As shown by research efforts conducted during the last decade, the eye is not exempt from the systemic inflammatory process and may be involved in almost all of the most frequent AIDs, with several distinct peculiarities. Ocular affections may severely impact patients' quality of life due to orbital pain, impairment of visual acuity, and/ or long-term, sight-threatening complications. Consequently, in the context of a multidisciplinary team, ophthalmologists should be aware of ocular manifestations related to these disorders as they may have a dominant diagnostic weight in patients with a challenging presentation as well as a salient role in therapeutic choice in sight-threatening situations. This review describes a variety of aspects of ophthalmologic involvement in AIDs, looking at both well-recognised eye manifestations as well as rarely reported ocular presentations, with a particular focus on the recent literature.

Ocular Emergencies: Red Eye

"Red eye" is used as a general term to describe irritated or bloodshot eyes. It is a recognizable sign of an acute/chronic, localized/systemic underlying inflammatory condition. Conjunctival injection is most commonly caused by dryness, allergy, visual fatigue, contact lens overwear, and local infections. In some instances, red eye can represent a true ocular emergency that should be treated by an ophthalmologist. A comprehensive assessment of red eye conditions is required to preserve the patients visual function. Severe ocular pain, significant photophobia, decreased vision, and history of ocular trauma are warning signs demanding immediate ophthalmological consultation.

Treatment of rheumatoid arthritis with biologics may exacerbate HTLV-1-associated conditions: A case report

RATIONALE

There are roughly 5 to 10 million persons infected with human T-lymphotropic virus type 1 (HTLV-1) worldwide, and the safety of treating this population with biologics remains poorly understood.

PATIENT CONCERNS AND DIAGNOSIS

An HTLV-1-infected 66-year-old female with HTLV-1 uveitis (HU) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Her HU had been in remission and her HAM/TSP symptoms had been managed effectively with oral steroids for years. However, she developed severe rheumatoid arthritis (RA) after failing to respond well to conventional anti-rheumatic agents.

INTERVENTIONS

She was administered two intravenous 8mg/kg doses of the biologic tocilizumab.

OUTCOMES

Subsequently, her RA symptoms resolved, but she suffered a recurrence of HU and exacerbation of HAM/TSP symptoms. When she was switched back to steroid-based treatment, HU and HAM symptoms both improved, but RA symptoms again worsened. Finally, an attempt to substitute the biologic abatacept and reduce the steroids failed when HAM/TSP symptoms again became aggravated.

LESSONS

To the best of our knowledge, this represents the first report worldwide of a biologic aggravating HTLV-1-associated conditions. This report suggests that caution is advised when using biologics to treat HTLV-1-infected patients, though further research is required to clarify the situation.

Quantifying Retinal Microvascular Changes in Uveitis Using Spectral-Domain Optical Coherence Tomography Angiography

PURPOSE

To quantify retinal capillary density and morphology in uveitis using spectral-domain optical coherence tomography angiography (SD-OCTA).

DESIGN

Cross-sectional, observational study.

METHODS

Healthy and uveitic subjects were recruited from 2 tertiary care eye centers. Prototype SD-OCTA devices (Cirrus; Carl Zeiss Meditec, Inc, Dublin, California, USA) were used to generate 3 × 3-mm² OCTA images centered on the fovea. Subjects were placed into 3 groups based on the type of optical microangiography (OMAG) algorithm used for image processing (intensity and/or phase) and type of retinal segmentation (automatic or manual). A semi-automated method was used to calculate skeleton density (SD), vessel density (VD), fractal dimension (FD), and vessel diameter index (VDI). Retinal vasculature was assessed in the superficial retinal layer (SRL), deep retinal layer (DRL), and nonsegmented retinal layer (NS-RL). A generalized estimating equations model was used to analyze associations between the OCTA measures and disease status within each retinal layer. A P value < .05 was accepted as significant. Reproducibility and repeatability were assessed using the intraclass correlation coefficient (ICC).

RESULTS

The SD, VD, and FD of the parafoveal capillaries were lower in uveitic eyes compared with healthy eyes in all retinal segments. In addition, SD and VD were significantly lower in the DRL of subjects with uveitic macular edema. There was no correlation in any capillary parameters and anatomic classification of uveitis.

CONCLUSIONS

Quantitative analysis of parafoveal capillary density and morphology in uveitis demonstrates significantly lower capillary density and complexity. SD-OCTA algorithms are robust enough to detect these changes and can provide a novel diagnostic index of disease for uveitis subjects.

Anti-TNFα Treatment for HLA-B27-Positive Ankylosing Spondylitis-Related Uveitis

PURPOSE

To assess the long-term efficacy of the most widely used anti-tumor necrosis factor alpha (TNFα) agents for treatment of HLA-B27-positive ankylosing spondylitis (AS)-related uveitis.

DESIGN

Retrospective cohort study.

METHODS

The medical records of 143 patients with HLA-B27-positive AS who visited Seoul St. Mary's Hospital and were taking an anti-TNFα agent for at least 1 year were studied. Subjects were divided into 3 groups according to anti-TNFα treatment: Group 1 (infliximab, 66), Group 2 (adalimumab, 45), and Group 3 (etanercept, 32).

RESULTS

Mean age was 41.0 ± 13.0 years, and 97 patients (67.8%) were male. Mean follow-up period was 70.6 ± 37.9 months. In cases of active ocular inflammation at the onset of anti-TNFα treatment, patients showed improved activity of uveitis after 24.0 ± 15.0 days (Group 1), 17.9 ± 6.0 days (Group 2), and 25.9 ± 18.0 days (Group 3). After the anti-TNFα treatment, 71 of 94 patients (32 [76.2%] in Group 1, 26 [78.8%] in Group 2, and 13 [68.4%] in Group 3) remained without uveitis relapse. A reduction in the number of systemic medications was achieved in 129 patients (90.2%). Twenty-eight cases of minor side effects were observed, and 4 cases were tuberculosis leading to discontinuation of anti-TNFα treatment.

CONCLUSIONS

Infliximab, adalimumab, and etanercept were effective for treating and reducing the number of uveitis relapses in HLA-B27-positive AS. However, the risk of serious infections was noted, so ophthalmologists should consider the possibility that prolonged use of biologic agents may result in systemic side effects.

[Association between optical coherence tomography findings and visual acuity of Behcet's disease-associated uveitis patients during remission stage]

OBJECTIVE

To study the relationship between the structure of macular central fovea and the best-corrected visual acuity (BCVA) during remission stage of Behcet's disease associated uveitis.

METHODS

Retrospective case series studies. The study covered 51 patients (79 eyes) during remission stage of Behcet's disease-associated uveitis from Peking Union Medical College Hospital in a three-year period from January 2012 to January 2015. There were 40 males, 11 females with the average age of 31.5 ± 6.9 years old (ranging from 18 to 46). All the patients received a complete set of ophthalmic examination, including BCVA, intraocular pressure, slit-lamp microscope, ophthalmoscope and frequency domain optical coherence tomography (OCT). All the eyes were divided into 4 groups according to central macular thickness (CMT) (the thick CMT group: CMT ≥ 130 µm; the thin CMT group: CMT < 130 µm) and the existence of ellipsoid zone. Group 1: thick CMT and ellipsoid (+); Group 2: thick CMT and ellipsoid (-); Group 3: thin CMT and ellipsoid (+); Group 4: thin CMT and ellipsoid (-). Sight disparity among multiple groups was tested with Kruskal Wallis, while the difference between two groups was tested with Mann-Whitney U test. Bonferroni correction was conducted when necessary.

RESULTS

The mean CMT was (151.4 ± 62.3) µm in all eyes (43 eyes in thick CMT group, 36 eyes in thin CMT group). According to grouping rule, there were 32 eyes in group 1, 11 eyes in group 2, 2 eyes in group 3 and 34 eyes in group 4. The BCVA of thick CMT group was better than that of thin CMT group (logMAR0.1 and logMAR1.0) (z = -6.88, P < 0.01). In addition, the BCVA of ellipsoid (+) group was better than the ellipsoid (-) group. (log MAR0.1 and log MAR1.0) (z = -6.60, P < 0.01).

CONCLUSION

Thick CMT and intact ellipsoid zone usually associated with relatively better BCVA in Behcet's disease-associated uveitis patients.

Ocular and systemic features of sarcoidosis and correlation with the International Workshop for Ocular Sarcoidosis diagnostic criteria

PURPOSE

To describe the ocular and systemic features in biopsy proven (definite) and non-biopsy proven (clinical) ocular sarcoidosis and to compare the ocular features with those proposed by the International Workshop for Ocular Sarcoidosis (IWOS).

METHODS

Retrospective chart review of 83 patients who attended a tertiary referral uveitis clinic and were diagnosed with sarcoidosis. Patients were divided into two groups based on the type of diagnosis: those who had tissue biopsy confirmed diagnosis 'definite sarcoidosis' (n= 42; 50.60 %) and those who had 'clinical sarcoidosis' (n= 41; 49.40%). Ocular and systemic manifestations, including lung function tests and bronchoalveolar lavage findings were compared in the two groups. The ocular features were also compared with the categories laid down by the International Workshop on Ocular Sarcoidosis (IWOS).

RESULTS

The mean age at presentation was 38.75 years (SD=12.33), 55.42% patients were female and mean follow-up was 24.35 months (SD=18.35). Trabecular meshwork nodules and/or tent-shaped PAS (category II of IWOS) were observed more frequently in patients with biopsy proven sarcoidosis (26.19 % v/s 9.76%; p=0.08). After logistic regression analysis, the predictor coefficient curve showed area under curve of 0.7262. Lymphocytosis (38.61% and 28.02%, p=0.93) and monocytosis (55.11% and 53.83%, p=0.56) on bronchoalveolar lavage analysis was present in both the groups, highlighting presence of granulomatous disease.

CONCLUSION

This study suggests high reliability for the clinical diagnosis of ocular sarcoidosis in patients with signs recommended by IWOS and that our diagnostic criteria are consistent with that of the IWOS.

The role of sex in uveitis and ocular inflammation

Uveitides can be due to non-infectious and infectious etiologies. It has been observed that there is a gender difference with a greater preponderance of non-infectious uveitis in women than in men. This review will describe both non-infectious and infectious uveitides and describes some of the current autoimmune mechanisms thought to be underlying the gender difference. It will specifically look at non-infectious uveitides with systemic involvement including juvenile idiopathic arthritis, spondyloarthopathies, sarcoidosis, Behçet’s disease, and Vogt-Koyanagi-Harada disease and at uveitides without systemic involvement including sympathetic ophthalmia, birdshot chorioretinitis, and the white dot syndromes. Infectious uveitides like acute retinal necrosis, progressive outer retinal necrosis, and cytomegalovirus mediated uveitis will be mentioned. Different uveitides with female- or male- predominance are presented and discussed.

Long-term clinical outcome and causes of vision loss in patients with uveitis

PURPOSE

To evaluate the long-term clinical and functional outcome, risks, and causes of vision loss and burden of disease among patients with uveitis.

DESIGN

Cross-sectional study.

PARTICIPANTS

The study included 1076 patients diagnosed with uveitis who attended the uveitis clinic at Moorfields Eye Hospital, London, United Kingdom, between 2011 and 2013.

METHODS

Information was gathered from the notes of all patients who were examined in the clinic.

MAIN OUTCOME MEASURES

Best-corrected visual acuity (BCVA), causes of moderate vision loss (MVL; 20/50-20/120), and severe vision loss (SVL; ≤ 20/200).

RESULTS

The study included 1799 eyes of 1076 patients with an average follow-up of 7.97 ± 0.17 years (median, 5.6 years; range, 1 month-54 years; 8159 patient-years; 14 226 eye-years). Average BCVA remained stable for patients with anterior uveitis (20/30 at baseline to 20/33 at 10 years), as well as for those with nonanterior uveitis (20/50 at baseline to 20/47 at 10 years). Vision loss was noted in 19.2% of eyes, with an incidence for MVL of 0.01 per eye-year or 0.02 per patient-year and for SVL of 0.01 per eye-year or 0.02 per patient-year. Patients were more at risk of vision loss if they had non-anterior uveitis disease, vitreous opacities, retinal detachment, cystoid macular edema (CME), macular scarring, macular hole, optic neuropathy, or macular ischemia. Chronic CME was the most common cause of MVL (3.55%), and macular scarring was the most common cause for irreversible SVL (4%). Among 525 patients (48.7%) who received oral prednisolone, 320 (61%) required a dose of more than 40 mg/day and 130 (24.8%) also required 1 or more second-line agents. Patients were reviewed on average 33.7 ± 0.7 times or 5.9 ± 0.46 times/year.

CONCLUSIONS

Long-term functional outcome among uveitis patients is good, with BCVA remaining stable for more than 10 years of follow-up. In cases when vision loss occurs, it is related mainly to retinal changes. The burden on clinical services is similar regardless of the severity of disease or the risk of vision loss.

[Alternation of retinal complement system in a mouse model of lipopolysaccharide- induced uveitis]

OBJECTIVE

To investigate the activation of the complement system in the retina in a mouse model of endotoxin-induced uveitis (EIU).

METHODS

Balb/c mice were randomly divided into control group and lipopolysaccharide (LPS)-induced EIU group. Twenty-four hours after modeling, the expressions of the major complement components of the classical pathway (CP), mannose-binding lectin (MBL) pathway, alternative pathway (AP), and terminal pathway in the retina were determined by quantitative RT-PCR. Western blotting was employed to examine the protein expressions of the key components of the complement system involved in the CP and AP pathways in the retina.

RESULTS

s Normal mouse retina expressed a variety of complement components that were involved mainly in the CP and AP pathways. The expressions of the complement components involved in the CP and AP pathways were up-regulated in the retina of mice with EIU. Although MASP1 and MASP2 were detected in the retina in both the EIU and control groups, their expressions were weak and showed no significant difference between the two groups.

CONCLUSION

The AP and CP but not the MBL pathways of the complement system are activated in the retina of mice with EIU, suggesting a role of the activated complement system in the pathological process of EIU.

Visual acuity and microperimetric mapping of lesion area in eyes with inflammatory cystoid macular oedema

PURPOSE

  To evaluate the effect of fluid accumulation on local visual function in inflammatory cystoid-macular-edema (ICME).

METHODS

  This cross-sectional study applied optical-coherence-tomography over a 12×12 fovea-centered field in 50 patients with ICME and mapped the extent of fluid-filled spaces in various retinal layers, of subretinal-fluid and of diffuse-edema. Regression analysis examined effect of planimetric fluid-distribution on best-corrected-visual-acuity (BCVA) and mean microperimetric-sensitivity.

RESULTS

  BCVA decreased with increasing central-neuroretinal-thickness (r= 0.52, p= 0.001), total central-retinal-thickness, including subneuroretinal-fluid (r= 0.41, p= 0.006), total cystoid-and-diffuse edema-area (r= 0.35, p= 0.036) and cystoid inner-nuclear-layer area (r= 0.39, p= 0.02). Mean retinal-sensitivity decreased with increasing diffuse edema-area (r= -0.86, p<0.0001), total cystoid-and-diffuse edema-area (r= -0.54, p= 0.001), cystoid inner-nuclear-layer area (r= -0.46, p= 0.008) and cystoid ganglion-cell-layer area (r= -0.6, p=0.049), central-neuroretinal-thickness (r= -0.42, p= 0.028) and total central-retinal-thickness (r= -0.34, p= 0.039). In multivariate-analyses BCVA was best described by central-neuroretinal-thickness, duration of edema, total cystoid-and-diffuse edema-area and cystoid inner-nuclear-layer area (R(2) = 0.5, p= 0.002). Mean retinal-sensitivity was best described by diffuse edema-area, total cystoid-and-diffuse edema-area and central-neuroretinal-thickness (R(2) = 0.75, p< 0.0001). Subretinal-fluid area and cystoid outer-nuclear/Henle's layer area had no effect on either BCVA or microperimetry.

CONCLUSIONS

  Thickening of the neurosensory-fovea, not subfoveal-fluid, had major impact on both BCVA and retinal-sensitivity. The extent of edema in inner retinal layers also had major impact on both of these two functional parameters. Visual-impairment seems to differ depending on the layers involved, thus different types of fluid accumulation may potentially be given varying treatment priorities.

Dexamethasone intravitreal implant (Ozurdex) for the treatment of pediatric uveitis

PURPOSE

To report our experience using Ozurdex (Allergan, Irvine, CA), a biodegradable intravitreal implant containing of 0.7 mg of dexamethasone approved for use in adults with noninfectious uveitis in adults, in the treatment of pediatric uveitis.

METHODS

The medical records of consecutive patients with noninfectious posterior uveitis who were unresponsive to standard treatment and subsequently received the Ozurdex implant from March 2011 to March 2013 were retrospectively reviewed.

RESULTS

A total of 14 eyes of 11 patients (mean age, 10.1 years; range 4-12) received 22 Ozurdex implants during the study period. Of the 11 patients, 7 had idiopathic intermediate or posterior uveitis, 1 had sympathetic ophthalmia, 2 had juvenile idiopathic arthritis, and 1 had sarcoidosis. All patients were uncontrolled with standard treatment, including topical or sub-Tenon's or systemic corticosteriods and/or immune-modulation. Visual acuity improved after Ozurdex implant in 5 of 8 patients (63%). Intraocular inflammation was controlled or improved after 17 of 22 of implants (12 eyes [77%]). The frequency of topical corticosteroids was decreased and/or discontinued after 18 of 22 implants (12 eyes [82%]). Complications included implant migration into the anterior chamber (4 aphakic eyes), increased intraocular pressure (5 eyes), and progression of a preexisting cataract (1 eye). The uveitis reoccurred in 57% of eyes at 4.3 months (2-7 months) after injection.

CONCLUSIONS

The Ozurdex implant in combination with systemic immunomodulatory therapy resulted in improved visual acuity, control of intraocular inflammation, and a decrease in corticosteroid use. In the majority of eyes the uveitis reoccurred around 4 months after injection. The adverse events in our study are similar to those identified in adult studies.

The frequency and outcome of uveitis in patients with newly diagnosed juvenile idiopathic arthritis in two 4-year cohorts from 1990-1993 and 2000-2003

OBJECTIVES

To retrospectively compare the frequency and outcome of uveitis between two cohorts of patients with newly-onset juvenile idiopathic arthritis (JIA) separated by a 10 year interval.

METHODS

The diagnosis of JIA was made in 239 patients in 1990-1993 and in 240 patients in 2000-2003 by paediatric rheumatologists at the Rheumatism Foundation Hospital, Heinola, Finland. An ophthalmologist examined all the patients regularly and diagnosed uveitis. The demographics of the patients, type of JIA, frequency, medical treatment and outcome of uveitis were documented.

RESULTS

The main outcome measures were the frequency and outcome of uveitis, the number of complications and the best corrected visual acuity (BCVA), need of corticosteroids and other immunosuppressive treatment. The frequency of uveitis was higher (25% vs. 18%) in the earlier cohort. The visual outcome was ≥0.5 in all JIA-uveitis patients except one in the earlier cohort. Complications were fewer (21% vs. 35%) and uveitis was milder according to the Standardisation of Uveitis Nomenclature (SUN) criteria in the later cohort. Remission of uveitis (33% vs. 42%) and arthritis (20% vs. 23%) in JIA-uveitis patients was similar in both cohorts after a follow-up of 6.6 and 5.9 years, respectively. Systemic corticosteroids were more commonly used (25% vs. 7%) in JIA-uveitis patients of the earlier cohort but the use of methotrexate was equal in both cohorts (65% vs. 67%).

CONCLUSIONS

In this study with early and aggressive treatment and close monitoring the outcome of JIA-uveitis patients was favourable and visual loss was avoided in most cases.

Behcet's disease: systemic and ocular manifestations

AIM

The aim of this study was to evaluate if patients with Behcet's disease who have ocular involvement have a more severe form of this disease as compared to patients with Behcet's disease alone.

METHODS

A total of 99 patients were included in the study. 76 patients were used as part of the examined group, and 23 patients formed a control group.

RESULTS

The following are the results of examined and control groups, respectively: recurrent oral aphthous ulcers 89.5%, 95.7%; genital ulcers 61.8%, 97.0%; articular involvement 72.4%, 65.2%; vasculitis 81.6%, 60.9%; positive pathergy test 25.0%, 47.8%. Higher frequency of genital ulcerations was noted in control group (P = 0.001). More than two major criteria were met in 100% of the cases. HLA B51 was present in 78.9% of the cases in the examined group and 43.5% of the cases in control group; thus there is significant difference between them (P = 0.001). Visual acuity >0.5 occurred in 76% (examined group). Most frequent ocular manifestations in the examined group were retinal periphlebitis 81.6%, periphlebitis and periarteritis 65%, and serofibrinous uveitis 63.2%. Macular edema as a complication was present in 63.2%. The majority of patients (55.3%) were treated with combined therapy consisting of cyclosporine A and systemic corticosteroids. In 38.2% of patients, laser photocoagulation was used on retinal periphery.

Comparative analysis of induced vs. spontaneous models of autoimmune uveitis targeting the interphotoreceptor retinoid binding protein

Animal models of autoimmunity to the retina mimic specific features of human uveitis, but no model by itself reproduces the full spectrum of human disease. We compared three mouse models of uveitis that target the interphotoreceptor retinoid binding protein (IRBP): (i) the "classical" model of experimental autoimmune uveitis (EAU) induced by immunization with IRBP; (ii) spontaneous uveitis in IRBP T cell receptor transgenic mice (R161H) and (iii) spontaneous uveitis in Autoimmune Regulator (AIRE)(-/-) mice. Disease course and severity, pathology and changes in visual function were studied using fundus imaging and histological examinations, optical coherence tomography and electroretinography. All models were on the B10.RIII background. Unlike previously reported, IRBP-induced EAU in B10.RIII mice exhibited two distinct patterns of disease depending on clinical scores developed after onset: severe monophasic with extensive destruction of the retina and rapid loss of visual signal, or lower grade with a prolonged chronic phase culminating after several months in retinal degeneration and loss of vision. R161H and AIRE(-/-) mice spontaneously developed chronic progressive inflammation; visual function declined gradually as retinal degeneration developed. Spontaneous uveitis in R161H mice was characterized by persistent cellular infiltrates and lymphoid aggregation, whereas AIRE(-/-) mice characteristically developed multi-focal infiltrates and severe choroidal inflammation. These data demonstrate variability and unique distinguishing features in the different models of uveitis, suggesting that each one can represent distinct aspects of uveitis in humans.

[Efficiency evaluation of non-infectious uveitis]

Authors compared clinical and economic effeciency of treatment of the classical corticosteroids therapy and modern immunosuppressive treatment or their combination. Retrospective evaluation carried out in 2012, covering 2006-2011, monitored sample of 27 patients, 16 women and 11 men, 45 eyes with disabilities. The average age in the last year of follow-up monitoring was 30.2, ranging from 14 to 76 years. The mean duration of disease for the whole sample is 16.5 years with a range from 6 to 36 years. Three basic diagnoses were included in investigated group: chronic iridocyclitis in 59 % of eyes, intermediate uveitis in 30 % of eyes and sympathetic ophthalmia in 11 % of eyes. The optimal treatment not be determined, however, combined corticosteroid sparing therapy was the most beneficial to maintain in terms of visual acuity with minimal side effects and cost effectiveness. Successful outcomes of treatment were observed for intermediate uveitis, because the visual acuity improved in nine letetters of ETDRS chart in the study. Satisfactory treatment was proved in chronic iridocyclitis and sympathetic ophthalmia in general, because visual acuity improved in a few letters of ETDRS chart, in the same line as in the beginning of the six-year follow-up. Rounded average annual prize for treatment including pharmacotherapy, outpatient and inpatient care and laboratory follow-up was in chronic iridocyclitis € 990, in intermediate uveitis € 310 and sympathetic ophthalmia € 1550. Pharmacotherapy exceeded the financial appraisal of specialized medical and inpatient care in total cost. Key words: uveitis, corticosteorids, immunosuppression, costeffectivness.

Use of optical coherence tomography and electroretinography to evaluate retinal pathology in a mouse model of autoimmune uveitis

Experimental autoimmune uveoretinitis (EAU) in mice is a model for human autoimmune uveitis. Longitudinal follow-up is only possible by non-invasive techniques, but the information obtained by visual fundus examination can be limited. We therefore evaluated the efficacy of optical coherence tomography (OCT) and electroretinography (ERG) to monitor pathological and functional changes of the retina in vivo. OCT imaging and ERG recording as a measure of visual function were compared with visual fundoscopic imaging and histology findings in the same mouse. Our results showed that OCT imaging of the retina was well correlated with clinical and histological observations in mice during EAU. However, OCT imaging was more sensitive than fundoscopic imaging in detecting the cell infiltrates at the early phase of disease onset. Furthermore, by allowing multi-layer cross- and horizontal-sectional visualizations of retinal lesions longitudinally in a noninvasive fashion, OCT added information that could not be obtained by fundoscopic and histological examinations. Lastly, retinal thickness obtained by OCT imaging provided a key indicator reflecting disease activity, which showed a close association with visual dysfunction as measured by ERG recordings in EAU mice. Thus, our findings demonstrate that OCT is a highly sensitive and reliable technique, and a valuable method for the semi-quantitative evaluation of retinal inflammation in vivo in the mouse.

Retinal blood flow velocity in patients with active uveitis using the retinal function imager

BACKGROUND

Previous studies suggest a link between macular edema and retinal blood flow velocity (RBFV). The effects of inflammation in the retinal blood vessels are not clearly understood. We want to evaluate the differences in retinal blood flow velocities of patients with active uveitis and healthy controls using the retinal function imager (RFI) and determine the correlation between retinal blood flow velocity and central macular thickness in uveitis patients.

METHODS

Twenty-eight eyes of 24 patients with active anterior uveitis and 51 eyes of 51 normal control subjects were enrolled. Retinal blood flow velocities evaluated by RFI and central macular thickness evaluated by optical coherence tomography (SLO-OCT) were obtained. Differences among the groups were assessed using Stata statistical software.

RESULTS

Ten eyes had uveitic cystoid macular edema (CME). Median (first quartile, third quartile) venous velocity for uveitic eyes with CME, uveitic eyes without CME, and controls were 2.09 (1.92, 2.44), 2.64 (2.32, 2.86), and 2.82 (2.39, 3.53) mm/s respectively. Median (first and quartile) arterial velocity for uveitic eyes with CME, uveitic eyes without CME, and controls were 3.79 (3.61, 4.09), 3.46 (2.86, 4.12), and 3.93 (3.35, 4.65) mm/s. Uveitic eyes with CME had significantly lower venous velocity than controls (P = 0.044). There was a strong linear relationship between venous velocity and central retinal thickness (P = 0.007).

CONCLUSIONS

Retinal venous velocities were significantly decreased in eyes with uveitic CME relative to controls. Decreased venous velocity was correlated with increased central retinal thickness in uveitic eyes.

Favourable outcome after cataract surgery with IOL implantation in uveitis associated with juvenile idiopathic arthritis

PURPOSE

Management of uveitic cataract in patients with juvenile idiopathic arthritis (JIA) is challenging, and intraocular lens (IOL) implantation is controversial. This study investigated the outcome after minimally invasive surgery with IOL implantation.

METHODS

Retrospective analysis after phacoemulsification with in-the-bag IOL implantation was performed in 16 patients (17 operations) with ANA-positive JIA-associated chronic uveitis. In these patients, 25 G capsulectomy and anterior vitrectomy was performed and they received an intravitreal triamcinolone (TA) injection.

RESULTS

  Mean age at uveitis onset was 5 ± 2 years, and surgery was performed at a mean age of 11 ± 2.2 years. Preoperatively, uveitis was inactive in all patients, and visual acuity was logMAR 0.8 ± 0.44; additional uveitis complications were present in all patients, and 15 patients were receiving systemic immunosuppression/biologicals. After surgery (mean follow-up 26.5 ± 11.7 months), presence of cystoid macular oedema, papilloedema, ocular hypertension/glaucoma and hypotony did not increase compared with baseline. There was no significant worsening of AC inflammation (by cell numbers and laser flare values). IOL deposits persisted in four patients, and synechiae developed in eight. The visual acuity was improved (≥2 lines) in all patients (mean logMAR 0.3 ± 0.24). Retrolental membrane formation was not noted. Secondary capsular opacification was observed in seven patients, requiring Nd:YAG capsulotomy in five of them.

CONCLUSIONS

Phacoemulsification and in-the-bag IOL implantation may improve visual outcome in JIA-associated uveitis with minimally invasive surgical technique and intravitreal TA injection. Well-controlled uveitis with appropriate use of topical steroids and systemic immunosuppression or biologicals appears as a perioperative requirement.

Three-year visual and anatomic results of administrating intravitreal bevacizumab in inflammatory ocular neovascularization

OBJECTIVE

To assess the 3-year visual outcome of intravitreal bevacizumab in inflammatory ocular neovascularization.

DESIGN

Experimental study.

METHODS

Retrospective multicenter consecutive case series in 81 patients with inflammatory ocular neovascularization refractory to standard therapy and treated with intravitreal bevacizumab. The outcome measures included improvement of best corrected visual acuity expressed as logarithm of minimum angle of resolution (logMAR) and paired comparison decrease in central foveal thickness by optical coherence tomography.

RESULTS

Mean best corrected visual acuity improved from baseline 0.699 (6/30 or 20/101) (SD 0.434) to 0.426 (6/16 or 20/53) (SD 0.428) (n = 81; p < 0.001), a gain of 2.7 lines (median 3 injections; 81 eyes; 81 patients). Paired comparisons revealed significant central foveal flattening at 3 years of 97.9 μm (n = 51; p < 0.001). In a subgroup analysis, visual improvement was significant for ocular histoplasmosis (p = 0.026); multifocal choroiditis (p = 0.05); serpiginous choroiditis (p = 0.028); ocular toxoplasmosis (p = 0.042); and punctate inner choroidopathy (p = 0.015). In a subgroup analysis, foveal flattening was significant for ocular histoplasmosis (p = 0.004); multifocal choroiditis (p = 0.007); serpiginous choroiditis (p = 0.011); and punctate inner choroidopathy (p = 0.001). Of the group, 5 eyes developed submacular fibrosis, 1 eye retinal pigment epithelial tear, and 1 eye macular ischemia in the context of vasculitis.

CONCLUSION

At 3 years, intravitreal bevacizumab sustained significant visual improvement of 2.7 lines and significant foveal flattening of 98 μm in a wide variety of inflammatory ocular diseases without major complications after a median of 3 injections.
