Abstract
A 54-year-old woman with cutaneous malignant melanoma developed Vogt-Kayanagi-Harada (VKH)-like uveitis induced by dabrafenib/trametinib therapy. Dabrafenib was discontinued but she continued to use trametinib due to the risk of disease progression. Intraocular inflammation resolved after cessation of dabrafenib and administration of topical and systemic corticosteroids. Our patient outlines the importance of recognizing VKH-like uveitis as a consequence of dabrafenib/trametinib therapy in melanoma patients and highlights a question about the potential role of each drug in developing uveitis.

Abstract
Bisphosphonates such as zoledronic acid are an important part of adjuvant therapy to reduce the risk of recurrence in early-stage breast cancer. Uveitis remains one of the lesser-known side effects of zoledronic acid; prompt recognition is essential to ensure patients receive appropriate and timely care to help prevent permanent vision loss. We report a case of anterior uveitis in a postmenopausal woman who presented with visual symptoms after receiving the first dose of zoledronic acid. This case report serves to educate and increase awareness of the risk of uveitis in patients who are given zoledronic acid. This is the first and only reported case of zoledronic acid when used in the adjuvant setting for the treatment of breast cancer.

Abstract
Juvenile idiopathic arthritis (JIA), the most common chronic rheumatologic condition in childhood, remains a cause of significant morbidity, particularly in those with spondyloarthropathy, including psoriatic arthritis (PsA) and enthesitis-related arthritis (ERA). While secukinumab was recently approved for the treatment of children and adolescents with ERA and PsA, there is limited published data on its use in JIA, particularly in refractory cases, despite its efficacy in the treatment of adult arthritis. We aim to examine the use of this therapy in JIA in a single pediatric rheumatology center. A retrospective chart review was performed and 10 JIA patients who received treatment with secukinumab were identified. Data extracted included disease activity, patient demographics, comorbidities, medications, and laboratory data. Seven ERA, 2 PsA, and 1 poly JIA patient were treated with secukinumab at our center between April 2011 and July 2021. These patients had notably resistant disease, with a mean disease-modifying antirheumatic drug (DMARD) failure rate of 3.8. One hundred percent of patients who underwent magnetic resonance imaging (MRI) after being on at least 3 months of secukinumab therapy demonstrated improvement in their MRI findings. One patient developed a flare of uveitis while on secukinumab therapy, with no other adverse events recorded in our patients. Secukinumab therapy was recently approved for children and adolescents with ERA and PsA, and may offer an efficacious option given its demonstrated improvement in imaging and joint examination, as well as qualitative reports of pain, even in those who have failed other therapies. However, caution may be warranted in those with a history of uveitis and warrants further study.

Epidemiol Rev 2022; 44:2-16. [PMID: 35442407 PMCID: PMC10362938 DOI: 10.1093/epirev/mxac001] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Revised: 02/01/2022] [Accepted: 03/03/2022] [Indexed: 12/29/2022] Open
Abstract
The uveitides consist of >30 diseases characterized by intraocular inflammation. Noninfectious intermediate, posterior, and panuveitides typically are treated with oral corticosteroids and immunosuppression, with a similar treatment approach for most diseases. Because these uveitides collectively are considered a rare disease, single-disease trials are difficult to impractical to recruit for, and most trials have included several different diseases for a given protocol treatment. However, measures of uveitis activity are disease specific, resulting in challenges for trial outcome measures. Several trials of investigational immunosuppressive drugs or biologic drugs have not demonstrated efficacy, but design problems with the outcome measures have limited the ability to interpret the results. Successful trials have included diseases for which a single uveitis activity measure suffices or a composite measure of uveitis activity is used. One potential solution to this problem is the use of a single, clinically relevant outcome, successful corticosteroid sparing, defined as inactive uveitis with a prednisone dose ≤7.5 mg/day coupled with disease-specific guidelines for determining inactive disease. The clinical relevance of this outcome is that active uveitis is associated with increased risks of visual impairment and blindness, and that prednisone doses ≤7.5 mg/day have a minimal risk of corticosteroid side effects. The consequence of this approach is that trial visits require a core set of measures for all participants and a disease-specific set of measures, both clinical and imaging, to assess uveitis activity. This approach is being used in the Adalimumab Versus Conventional Immunosuppression (ADVISE) Trial.

[PMID: 36399176 PMCID: PMC10050064 DOI: 10.1007/s00417-022-05893-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 08/31/2022] [Accepted: 11/03/2022] [Indexed: 11/19/2022] Open
Abstract
Abstract
Purpose
To evaluate the effectiveness of 0.19-mg fluocinolone acetonide implant (FAi) for preventing inflammatory relapses in noninfectious uveitis with posterior segment involvement in standard clinical practice. Further, to assess the value of remission induction therapy with intraocular and periorbital administered high-dose corticosteroids before FAi.
Methods
A retrospective cohort study in a tertiary referral center specialized in uveitis management. The primary study outcomes were the best-corrected visual acuity (BVCA) and central retinal thickness (CRT) within a 12-month observation period. The secondary outcomes were intraocular pressure (IOP) and intraocular inflammation. The main safety measures were IOP increase and cataract formation.
Results
In total, 76 eyes of 57 patients received FAi. Locally administered high-dose corticosteroids were applied in 68.4% of all eyes before FAi. BCVA remained stable within the 12-month observation period (63.21 vs. 62.95, difference 0.26 letters; 95% CI: − 6.31 to 6.84; p > 0.9). Significant CRT reduction upon FAi was sustained after 12 months (362.7 vs. 309.1 μm, difference 53.57 μm; 95% CI: 1.55 to 105.6; p = 0.04). Intraocular inflammation was reduced until 9 months of follow-up (0.82 vs. 0.3, difference 0.53; 95% CI: 0.11 to 0.95; p = 0.007). A mean IOP increase (13.68 vs. 15.6; difference − 1.92; 95% CI: − 3.85 to 0.004; p = 0.0507) and cataract development (20% of all phakic eyes) were noted.
Conclusion
We observed similar levels of FAi effectiveness for the treatment of noninfectious uveitis in standard clinical practice compared to previous randomized clinical trials. Moreover, remission induction therapy before FAi can benefit patients with increased baseline uveitis activity.

Abstract
BACKGROUND/AIMS To investigate the incidence, severity of COVID-19 infection and the outcomes in patients with uveitis treated with biologic agents during COVID-19 pandemic. METHODS In this prospective study, we included all patients with uveitis treated with biologic agents and tested for COVID-19 infection between May 2020 and October 2020. RESULTS A total of 59 patients were identified. Behçet's disease was the most common diagnosis (64.4%). Infliximab was the most frequent biologic agent used (61%). Nine (15.3%) patients were tested positive for COVID-19. None of the patients with positive COVID-19 test developed any COVID-19-related symptoms during follow-up. Of the nine patients with positive COVID-19 test, only two patients had uveitis flare-up after the biologic suspension. CONCLUSION Uveitis patients under biologic therapy can be silent carriers for COVID-19.

Abstract
Introduction Green tea extract (GTE) alleviated ocular inflammations in endotoxin-induced uveitis (EIU) rat model induced by lipopolysaccharide (LPS) but the underlying mechanism is unclear. Objectives To investigate the systematic and local mechanisms of the alleviation by untargeted metabolomics using liquid chromatography-tandem mass spectrometry. Methods Sprague-Dawley rats were divided into control group, LPS treatment group, and LPS treatment group treated with GTE two hours after LPS injection. The eyes were monitored by slip lamp and electroretinography examination after 24 hours. The plasma and retina were collected for metabolomics analysis. Results In LPS treated rats, the iris showed hyperemia. Plasma prostaglandins, arachidonic acids, corticosteroid metabolites, and bile acid metabolites increased. In the retina, histamine antagonists, corticosteroids, membrane phospholipids, free antioxidants, and sugars also increased but fatty acid metabolites, N-acetylglucosamine-6-sulphate, pyrocatechol, and adipic acid decreased. After GTE treatment, the a- and b- waves of electroretinography increased by 13%. Plasma phosphorylcholine lipids increased but plasma prostaglandin E1, cholanic metabolites, and glutarylglycine decreased. In the retina, tetranor-PGAM, pantothenic derivatives, 2-ethylacylcarinitine, and kynuramine levels decreased but anti-oxidative seleno-peptide level increased. Only phospholipids, fatty acids, and arachidonic acid metabolites in plasma and in the retina had significant correlation (p < 0.05, r > 0.4 or r < -0.4). Conclusions The results showed GTE indirectly induced systemic phosphorylcholine lipids to suppress inflammatory responses, hepatic damage, and respiratory mitochondrial stress in EIU rats induced by LPS. Phospholipids may be a therapeutic target of GTE for anterior chamber inflammation.

Abstract
PURPOSE To examine the incidence of uveitis in children prescribed prostaglandin analogs (PGAs) for glaucoma. METHODS In this dual-center cohort study, the medical records of consecutive patients <18 years old treated with a PGA between January 1, 2012, and December 31, 2018, were reviewed retrospectively. Patients with all forms of glaucoma, including those with a prior history of uveitis, were included. Patients who had been on a PGA prior to their first recorded visit were excluded. Patient charts were reviewed for new or recurrent uveitis during the first year of PGA therapy. RESULTS A total of 103 children (147 eyes) were included, with a total PGA exposure of 1,352 child-months. Ninety-eight children (142 eyes) tolerated the PGA without an episode of uveitis. Five patients with a documented prior history of uveitis experienced a unilateral episode of uveitis. A review of their medical records identified prescribed or unscheduled decrease in topical steroids or immunosuppressive medication as the most likely cause of uveitis recurrence. CONCLUSIONS This study provides further evidence that PGAs are unlikely to induce uveitis in children being treated for glaucoma and suggests that this may also be true in those with a history of uveitis. We are unable to evaluate whether PGAs make recurrence more likely or the tapering of steroids more difficult.

Abstract
PURPOSE To compare the relapse rate of sight-threatening noninfectious uveitis (NIU) in patients treated with infliximab (IFX) or adalimumab (ADA). DESIGN Observational retrospective multicenter study. METHODS A total of 330 patients (median age, 36 years; interquartile range, 27-54), 45.2% men) with sight-threatening NIU (ie, retinal vasculitis and/or macular edema) treated with anti-tumor necrosis factor [TNF]-α agents (IFX intravenously at 5 mg/kg at weeks 0, 2, 6, and every 4 to 6 weeks or ADA subcutaneously at 80 mg, then 40 mg every 2 weeks). Data were obtained retrospectively from patients' medical records. Main outcome measures were relapse rate, complete response of NIU, corticosteroid sparing effect, and safety. RESULTS Main etiologies of uveitis included Behçet disease (27%), idiopathic juvenile arthritis (5.8%), and sarcoidosis (5.5%). The estimated relapse rate at 6 months after introduction of biological agents was 13% (95% CI = 0.009-0.16). IFX was associated with less relapse risk than ADA (hazard ratio [HR] = 0.52, 95% CI = 0.36- 0.77, P = .001). ADA and IFX were comparable in terms of complete response rate of NIU as well as corticosteroid-sparing effect. Behçet disease was associated with higher odds of complete response (HR = 2.04, 95% CI = 1.16 -3.60, P = .01] and lower relapse rate (HR = 0.53, 95% CI = 0.33-0.85, P = .009) than other causes of NIU with anti-TNF-α agents. CONCLUSIONS In sight-threatening NIU, IFX seems to be associated with a lower relapse rate than ADA.

Abstract
Exogenous ganglioside GM1 has been reported to exert an immunomodulatory effect. We investigated the anti-inflammatory effect of GM1 ganglioside on endotoxin-induced uveitis (EIU) in rats and RAW 264.7 macrophages. Methods: EIU was induced in Lewis rats by administering a subcutaneous injection of lipopolysaccharide (LPS). GM1 was injected intraperitoneally for three consecutive days prior to the LPS injection. Twenty-four hours after the LPS injection, the integrity of the blood-aqueous barrier was evaluated by determining the protein concentration and number of infiltrating cells in the aqueous humor (AqH). Immunohistochemical and Western blot analyses of the iris-ciliary body (ICB) were performed to evaluate the effect of GM1 on the LPS-induced expression of cyclooxygenase-2 (COX-2) and intercellular adhesion molecule-1 (ICAM-1). The effect of GM1 on proinflammatory mediators and signaling cascades was examined in LPS-stimulated RAW 264.7 cells using Western blotting and immunofluorescence staining to further clarify the underlying anti-inflammatory mechanism. Results: GM1 significantly reduced the protein concentration and number of infiltrating cells in the AqH of rats with EIU. GM1 also decreased the LPS-induced expression of the ICAM-1 and COX-2 proteins in the ICB. In RAW 264.7 cells, GM1 inhibited the proinflammatory mediators induced by LPS, including inducible nitric oxide synthase (iNOS), COX-2, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6), and this inhibitory effect was potentially mediated by suppressing transforming growth factor-β-activated kinase 1 (TAK1) and reactive oxygen species (ROS)-mediated activation of nuclear factor-κB (NF-κB) and mitogen-activated protein kinases (MAPKs). Conclusions: Based on this study, GM1 may be a potential anti-inflammatory agent for ocular inflammatory diseases.

Abstract
PURPOSE To evaluate the risk factors associated with clinically important intraocular pressure (IOP) elevation with topical difluprednate treatment in patients with non-infectious uveitis. DESIGN Retrospective cohort study. METHODS Fifty-four eyes of 54 patients with non-infectious uveitis treated with topical difluprednate at the current institution were included. Demographics and clinical characteristics of uveitis patients were collected. The main outcome measure was development of clinically important IOP elevation defined as IOP ≥21 mmHg and an increase of ≥10 mmHg from baseline. RESULTS A clinically important IOP elevation was observed in 17 patients (31.5%). The mean time to clinically important IOP elevation was 7.4±4.8 weeks (range 3-19). Statistically significant risk factors for incident clinically important IOP elevation were being a child (adjusted hazard ratio [aHR] 7.85 [95% CI 1.48-41.56], P = .02) and concurrent use of systemic steroids (aHR 5.31 [95% CI 1.18-24.00], P = .03). Patients with concurrent systemic corticosteroids developed clinically important IOP elevation earlier than those without systemic corticosteroid (mean 5.7±3.4 [range 3-14] vs 10.4±5.7 [range 4-19] weeks, P = .05). Incident IOP ≥30 mmHg occurred in 7 patients (13.0%). All patients responded well to the cessation of difluprednate and/or use of topical antiglaucomatous agents and no eyes required glaucoma surgery. CONCLUSIONS This study demonstrated that clinically important IOP elevation is common in uveitis patients with topical difluprednate treatment. Children and patients with concurrent systemic corticosteroids are at substantial risk of developing clinically important IOP elevation.

Abstract
Purpose The purpose of this study was to elucidate the effects of interleukin (IL)-38 on experimental autoimmune uveitis (EAU) and its underlying mechanisms. Methods Mice with EAU were treated with IL-38, and the retinas and cervical draining lymph nodes (CDLNs) were analyzed by flow cytometry. Single-cell RNA sequencing (scRNA-seq) was conducted to analyze the immune cell profiles of CDLNs from normal, EAU, and IL-38-treated mice. Results Administration of IL-38 attenuated EAU symptoms and reduced the proportion of T helper 17 (Th17) and T helper 1 (Th1) cells in the retinas and CDLNs. In scRNA-seq analysis, IL-38 downregulated the IL-17 signaling pathway and reduced the expression of Th17 cell pathogenicity-related genes (Csf2 and Il23r), findings which were also confirmed by flow cytometry. In vitro, IL-38 reduced the granulocyte-macrophage colony-stimulating factor (GM-CSF) stimulation function of IL-23 and inhibited IL-23R expression in Th17 cells. Moreover, when co-cultured with Th17 cells, IL-38 prevented IL-23 production in antigen-presenting cells (APCs). Conclusions Our data demonstrate the therapeutic effect of IL-38 on EAU, and suggest that the effect of IL-38 may be caused by dampening of the GM-CSF/IL-23R/IL-23 feedback loop between Th17 cells and APCs.

Abstract
Uveitis is one of the main causes of blindness worldwide, and therapeutic alternatives are worthy of study. We investigated the effects of piperlongumine (PL) and/or annexin A1 (AnxA1) mimetic peptide Ac2-26 on endotoxin-induced uveitis (EIU). Rats were inoculated with lipopolysaccharide (LPS) and intraperitoneally treated with Ac2-26 (200 µg), PL (200 and 400 µg), or Ac2-26 + PL after 15 min. Then, 24 h after LPS inoculation, leukocytes in aqueous humor, mononuclear cells, AnxA1, formyl peptide receptor (fpr)1, fpr2, and cyclooxygenase (COX)-2 were evaluated in the ocular tissues, along with inflammatory mediators in the blood and macerated supernatant. Decreased leukocyte influx, levels of inflammatory mediators, and COX-2 expression confirmed the anti-inflammatory actions of the peptide and pointed to the protective effects of PL at higher dosage. However, when PL and Ac2-26 were administered in combination, the inflammatory potential was lost. AnxA1 expression was elevated among groups treated with PL or Ac2-26 + PL but reduced after treatment with Ac2-26. Fpr2 expression was increased only in untreated EIU and Ac2-26 groups. The interaction between Ac2-26 and PL negatively affected the anti-inflammatory action of Ac2-26 or PL. We emphasize that the anti-inflammatory effects of PL can be used as a therapeutic strategy to protect against uveitis.

Abstract
Lupeol is a pentacyclic triterpene with known anti-inflammatory effects. However, its role in the treatment of noninfectious uveitis has not been explored. This work investigated anti-inflammatory activity of lupeol in ocular tissues with in vitro and in vivo models. First, we evaluated the effect of lupeol (100 µM) on inflammatory response induced by lipopolysaccharide (LPS) in retinal pigment epithelium cells (ARPE-19) by measuring levels of released interleukins (IL-6 and IL-8). Then, we investigated the anti-inflammatory action of intravitreal lupeol in a rodent model of panuveitis induced by Mycobacterium bovis Calmette-Guérin Bacillus (BCG). Rats were submitted to electroretinography and clinical analyses on days 3, 7, and 15 after uveitis induction. In addition, histopathological analysis, and indirect quantification of myeloperoxidase (MPO) and N-acetylglucosaminidase (NAG) in the posterior segment were performed. Treatment with lupeol (100 µM) significantly decreased IL-6 and IL-8 levels in comparison to untreated LPS-activated ARPE-19 cells. This reduction was similar to that detected in ARPE-19 cells treated with dexamethasone. The results of the in vivo assay demonstrated that intravitreal lupeol is able to modulate inflammation in the anterior and posterior segment of the rat eyes, indicating that it should be further investigated as a novel potential candidate for management of uveitis.

Abstract
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.

The association between immune checkpoint or BRAF/MEK inhibitor therapy and uveitis in patients with advanced cutaneous melanoma. Eur J Cancer 2021; 144:215-223. [PMID: 33373866 DOI: 10.1016/j.ejca.2020.11.027] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 10/20/2020] [Accepted: 11/15/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND Treatment with immune checkpoint and BRAF/MEK inhibitors has significantly improved the survival of patients with advanced cutaneous melanoma and other metastatic malignancies. Therapy-related uveitis is a rare ocular adverse event, which may potentially lead to legal blindness. The epidemiology of treatment-related uveitis is currently insufficiently known. PATIENTS AND METHODS In this cohort study, we asked whether exposure to either immune checkpoint or BRAF/MEK inhibitors was associated with a higher risk of developing uveitis compared with the general population. Based on a Bayesian framework, we estimated the probability of developing uveitis with a right-censored, exponential survival model using data from the Zurich Melanoma Registry. The registry included all adult patients treated for advanced cutaneous melanoma between January 2008 and December 2018 at the University Hospital of Zurich, Switzerland. RESULTS In total, 304 patients (64%) were treated with immune checkpoint and 186 patients (38%) with BRAF/MEK inhibitors. Median follow-up time was 74 days (interquartile range: 57-233 days). Eleven patients developed uveitis and 30 patients died. We estimated the probability of developing uveitis per year in the general population as 0.05% (95% credibility interval [CrI]: 0.02%-0.1%). Corresponding posterior probabilities of treatment-related uveitis were 3.48% (95% CrI: 0.93%-7.49%) and 5.04% (95% CrI: 2.07%-9.19%) for immune checkpoint or BRAF/MEK inhibitors (posterior probability for difference: 76%). CONCLUSIONS Immune checkpoint and particularly BRAF/MEK inhibitor therapies are associated with an increase in the risk of developing uveitis. Treatment-related uveitis is not associated with systemic adverse events of immune checkpoint or BRAF/MEK inhibitors.

Abstract
We investigated how Src-homology 2-domain phosphatase-1 (SHP-1) regulates the inflammatory response in endotoxin-induced uveitis (EIU), and the signalling pathways involved. One week after intravitreal injection of short hairpin RNA targeting SHP-1 or SHP-1 overexpression lentivirus in rats, we induced ocular inflammation with an intravitreal injection of lipopolysaccharide (LPS). We then assessed the extent of inflammation and performed full-field electroretinography. The concentrations and retinal expression of various inflammatory mediators were examined with enzyme-linked immunosorbent assays and Western blotting, respectively. SHP-1 overexpression and knockdown were induced in Müller cells to study the role of SHP-1 in the LPS-induced inflammatory response in vitro. Retinal SHP-1 expression was up-regulated by LPS. SHP-1 knockdown exacerbated LPS-induced retinal dysfunction and increased the levels of proinflammatory mediators in the retina, which was abrogated by a c-Jun N-terminal kinase (JNK) inhibitor (SP600125). SHP-1 overexpression had the opposite effects. In Müller cells, the LPS-induced inflammatory response was enhanced by SHP-1 knockdown and suppressed by SHP-1 overexpression. SHP-1 negatively regulated the activation of the transforming growth factor-β-activated kinase-1 (TAK1)/JNK pathway, but not the nuclear factor-κB pathway. These results indicate that SHP-1 represses EIU, at least in part, by inhibiting the TAK1/JNK pathway and suggest that SHP-1 is a potential therapeutic target for uveitis.

Abstract
OBJECTIVES To compare the occurrence of non-infectious uveitis based on the type of tumour necrosis factor (TNF) inhibitor used to manage spondyloarthritis in ankylosing spondylitis (AS) patients. METHODS The occurrence (new-onset and recurrence) of uveitis was reviewed retrospectively in AS patients receiving different TNF inhibitor therapies (adalimumab [ADA], infliximab [IFX], etanercept [ETN], and golimumab [GOL]) for the management of spondyloarthritis from 2005 to 2018. Kaplan-Meier analysis was performed to calculate the cumulative occurrence rates of uveitis during TNF inhibitor therapy, and a log-rank test was used to analyse differences between the survival curves. Multivariable Cox proportional-hazards models were used to compute hazard ratios (HRs) of different TNF agents for uveitis occurrence after adjusting for concurrent confounding factors. RESULTS The three-year cumulative occurrence rates of uveitis were significantly different according to the type of anti-TNFs used (23.1% in IFX, 18.5% in ETN, and 11.9% in ADA+GOL group) (p=0.020). The risk of new-onset uveitis was similar for different drugs. However, the IFX group showed a 5.4 times higher risk of recurrence than the ADA+GOL group (p=0.022). After adjusting for other confounding factors, IFX use was independently associated with a more frequent occurrence of uveitis in AS patients (HR=2.01; p=0.011). CONCLUSIONS A significant number of AS patients who received anti-TNF therapy developed uveitis. Different types of anti-TNF drugs were associated with uveitis recurrence. Particularly, chimeric mouse-human monoclonal antibody (IFX) was found to increase the risk of uveitis occurrence compared to humanised monoclonal antibody (ADA or GOL).

Abstract
PURPOSE To report the clinical features, severity, and management of ocular immune-related adverse events (irAEs) in the setting of immune checkpoint inhibitor therapy for metastatic malignancies. METHODS Retrospective chart review at three tertiary ophthalmology clinics. Electronic medical records were reviewed between 2000 and 2017 for patients with new ocular symptoms while undergoing checkpoint inhibition therapy. RESULTS Eleven patients were identified. Ocular irAEs ranged from keratoconjunctivitis sicca to Vogt-Koyanagi-Harada-like findings. Average timing of irAEs from starting checkpoint inhibitor therapy was 15.7 weeks. Ocular inflammation was successfully controlled with corticosteroids in most cases, however three patients discontinue treatment as a result of ocular inflammation with decreased visual acuity, two discontinued due to progression of metastatic disease, and one discontinued due to severe systemic irAEs. CONCLUSION We found a wide spectrum of ocular irAEs associated with immune checkpoint inhibitors. In most cases, ocular AEs did not limit ongoing cancer treatment.

Br J Ophthalmol 2020; 104:1040-1044.

Abstract
BACKGROUND Of the side effects of prostaglandin analogues (PGAs), uveitis and cystoid macular oedema (CME) have significant potential for vision loss based on postmarket reports. Caution has been advised due to concerns of macular oedema and uveitis. In this report, we researched and summarised the original data suggesting these effects and determined their incidence. METHODS Preferred Reporting Items for Systematic review and Meta-Analyses guidelines were followed. Studies evaluating topical PGAs in patients with ocular hypertension or open angle glaucoma were included. MEDLINE, PubMed, EMBASE, CINAHL, Web of Science, Cochrane Library, LILACS and ClinicalTrials.gov were searched between 1946 and 2019. Experimental studies, animal studies and randomised studies with other intraocular pressure-lowering eye drops were excluded. RESULTS 214 studies (28 232 patients) met the inclusion criteria. Using prospective data, the incidence of uveitis and CME among PGA users were 62/28 232 (0.22%) and 25/28 232 (0.09%), respectively. A higher frequency of both uveitis and CME were found among latanoprost users compared with bimatoprost. There were 21 case studies reporting CME including 48 eyes in 43 patients. 47 of 48 eyes (97.9%) had previous incisional ocular surgery. 8 eyes were re-challenged, of which 7 (87.5%) recurred. 7 case studies reported uveitis in 15 eyes of 10 patients. 7 of 15 eyes (46.7%) were either pseudophakic or aphakic. 6 eyes were re-challenged, and all 6 (100%) recurred. CONCLUSIONS Cases of uveitis or CME revealed a confounding effect of ocular surgery, aphakia or subluxed intraocular lens. PGAs may be used in non-surgical patients without concern of causing CME or uveitis. The incidences of PGA-associated CME and uveitis are rare with limited prospective studies on the cause-effect relationship.

Abstract
Vemurafenib is a potent inhibitor of genetically activated BRAF, which is responsible for tumoral proliferation in cutaneous melanoma. A 56-year-old man receiving vemurafenib therapy presented with uveitis. Over the course of the disease, he developed bilateral, granulomatous uveitis with multiple peripheral chorioretinal lesions. Serum angiotensin-converting enzyme levels increased. The patient was diagnosed with probable ocular sarcoidosis related to vemurafenib and was treated with an intravitreal dexamethasone implant. This case is the first report that shows the clinical and angiographic features of a patient with vemurafenib-related sarcoid-like granulomatous uveitis.

Abstract
(1) Background: The cannabinoid 2 receptor (CB2R) is a promising anti-inflammatory drug target and development of selective CB2R ligands may be useful for treating sight-threatening ocular inflammation. (2) Methods: This study examined the pharmacology of three novel chemically-diverse selective CB2R ligands: CB2R agonists, RO6871304, and RO6871085, as well as a CB2R inverse agonist, RO6851228. In silico molecular modelling and in vitro cell-based receptor assays were used to verify CB2R interactions, binding, cell signaling (ß-arrestin and cAMP) and early absorption, distribution, metabolism, excretion, and toxicology (ADMET) profiling of these receptor ligands. All ligands were evaluated for their efficacy to modulate leukocyte-neutrophil activity, in comparison to the reported CB2R ligand, HU910, using an in vivo mouse model of endotoxin-induced uveitis (EIU) in wild-type (WT) and CB2R-/- mice. The actions of RO6871304 on neutrophil migration and adhesion were examined in vitro using isolated neutrophils from WT and CB2R-/- mice, and in vivo in WT mice with EIU using adoptive transfer of WT and CB2R-/- neutrophils, respectively. (3) Results: Molecular docking studies indicated that RO6871304 and RO6871085 bind to the orthosteric site of CB2R. Binding studies and cell signaling assays for RO6871304 and RO6871085 confirmed high-affinity binding to CB2R and selectivity for CB2R > CB1R, with both ligands acting as full agonists in cAMP and ß-arrestin assays (EC50s in low nM range). When tested in EIU, topical application of RO6871304 and RO6871085 decreased leukocyte-endothelial adhesion and this effect was antagonized by the inverse agonist, RO6851228. The CB2R agonist, RO6871304, decreased in vitro neutrophil migration of WT neutrophils but not neutrophils from CB2R-/-, and attenuated adhesion of adoptively-transferred leukocytes in EIU. (4) Conclusions: These unique ligands are potent and selective for CB2R and have good immunomodulating actions in the eye. RO6871304 and RO6871085, as well as HU910, decreased leukocyte adhesion in EIU through inhibition of resident ocular immune cells. The data generated with these three structurally-diverse and highly-selective CB2R agonists support selective targeting of CB2R for treating ocular inflammatory diseases.
