Fluocinolone intravitreal implant (Iluvien) for macular edema secondary to immune recovery uveitis in patient with acute myeloid leukemia

PURPOSE

To report the use of Fluocinolone intravitreal implant (Iluvien) for the treatment of persistent cystoid macular edema (CME) due to immune recovery uveitis syndrome in a patient with previous cytomegalovirus retinitis and acute myeloid leukemia.

DESIGN

Case report.

METHODS

The clinical history of a patient who received an Iluvien implant in one eye for the treatment of cystoid macular edema due to immune recovery uveitis syndrome, previously treated with peribulbar Triamcinolone and intravitreal Dexamethasone injections, was reviewed.

RESULTS

A 48-year-old woman presented with cystoid macular edema due to immune recovery uveitis syndrome. The patient had a history of cytomegalovirus retinitis 3.5 years prior, secondary to immunosuppressive treatment for an acute myeloid leukemia. Three periocular triamcinolone injections and two dexamethasone intravitreal implants were performed, but the edema recurred, so fluocinolone intravitreal implant was used, achieving a sustained control of the condition at one year of follow-up.

CONCLUSION

The Fluocinolone intravitreal implant may be an effective treatment for persistent CME in patients with immune recovery uveitis syndrome.

Hyper-Reflective Outer Nuclear Layer (HONL) in Vogt-Koyanagi-Harada Disease and Sympathetic Ophthalmia

PURPOSE

To describe the optical coherence tomography (OCT) findings of hyper-reflective outer nuclear layer (HONL) in two cases of stromal choroiditis (Vogt-Koyanagi-Harada disease - VKH, and sympathetic ophthalmia - SO).

METHODS

Case report.

RESULTS

Clinical and imaging findings of two patients (37-year-old female with VKH and 34-year-old male with SO) have been described. Both patients showed typical features of the disease with subretinal fluid accumulation and choroidal thickening on OCT. However, OCT of both patients at the initial visit revealed HONL, which was unusual in these conditions. During follow-up, OCT scans revealed thinning and atrophy of the outer retinal layers, irregular thickening of the retinal pigment epithelium, and irregular autofluorescence pattern on autofluorescence imaging.

CONCLUSIONS

The presence of HONL may serve as a poor prognostic factor in VKH and SO, resulting in thinning and atrophy of the outer retinal layers.

C-reactive protein-complement factor H axis as a biomarker of activity in early and intermediate age-related macular degeneration

Purpose

To determine and compare the serum levels of complement Factor H (FH), monomeric C-Reactive Protein (mCRP) and pentameric C-Reactive protein (pCRP) in patients with age-related macular degeneration (AMD) and to correlate them with clinical, structural and functional parameters.

Methods

Cross-sectional observational study. One hundred thirty-nine individuals (88 patients and 51 healthy controls) from two referral centers were included and classified into three groups: early or intermediate AMD (n=33), advanced AMD (n=55), and age and sex matched healthy controls (n=51). Serum levels of FH, mCRP, and pCRP were determined and correlated with clinical and imaging parameters.

Results

Patients with intermediate AMD presented FH levels significantly lower than controls [186.5 (72.1-931.8) µg/mL vs 415.2 (106.1-1962.2) µg/mL; p=0.039] and FH levels <200 µg/mL were associated with the presence of drusen and pigmentary changes in the fundoscopy (p=0.002). While no differences were observed in pCRP and mCRP levels, and mCRP was only detected in less than 15% of the included participants, women had a significantly higher detection rate of mCRP than men (21.0% vs. 3.8%, p=0.045). In addition, the ratio mCRP/FH (log) was significantly lower in the control group compared to intermediate AMD (p=0.031). Visual acuity (p<0.001), macular volume (p<0.001), and foveal thickness (p=0.034) were significantly lower in the advanced AMD group, and choroidal thickness was significantly lower in advanced AMD compared to early/intermediate AMD (p=0.023).

Conclusion

Intermediate AMD was associated in our cohort with decreased serum FH levels together with increased serum mCRP/FH ratio. All these objective serum biomarkers may suggest an underlying systemic inflammatory process in early/intermediate AMD patients.

Orbital/ocular inflammatory involvement in VEXAS syndrome: Data from the international AIDA network VEXAS registry

VEXAS syndrome is a recently described monogenic autoinflammatory disease capable of manifesting itself with a wide array of organs and tissues involvement. Orbital/ocular inflammatory manifestations are frequently described in VEXAS patients. The objective of this study is to further describe orbital/ocular conditions in VEXAS syndrome while investigating potential associations with other disease manifestations. In the present study, twenty-seven out of 59 (45.8 %) VEXAS patients showed an inflammatory orbital/ocular involvement during their clinical history. The most frequent orbital/ocular affections were represented by periorbital edema in 8 (13.6 %) cases, episcleritis in 5 (8.5 %) patients, scleritis in 5 (8.5 %) cases, uveitis in 4 (6.8 %) cases, conjunctivitis in 4 (6.8 %) cases, blepharitis in 3 (5.1 %) cases, orbital myositis in 2 (3.4 %) cases. A diagnosis of systemic immune-mediated disease was observed in 15 (55.6 %) cases, with relapsing polychondritis diagnosed in 12 patients. A significant association was observed between relapsing polychondritis and orbital/ocular involvement in VEXAS syndrome (Relative Risk: 2.37, 95 % C.I. 1.03-5.46, p = 0.048). Six deaths were observed in the whole cohort of patients after a median disease duration of 1.2 (IQR=5.35) years, 5 (83.3 %) of which showed orbital/ocular inflammatory involvement. In conclusion, this study confirms that orbital/ocular inflammatory involvement is a common finding in VEXAS patients, especially when relapsing polychondritis is diagnosed. This makes ophthalmologists a key figure in the diagnostic process of VEXAS syndrome. The high frequency of deaths observed in this study seems to suggest that patients with orbital/ocular involvement may require increased attention and more careful follow-up.

Effectiveness and Safety of Biosimilars in Pediatric Non-infectious Uveitis: Real-Life Data from the International AIDA Network Uveitis Registry

INTRODUCTION

Since many biological drug patents have expired, biosimilar agents (BIOs) have been developed; however, there are still some reservations in their use, especially in childhood. The aim of the current study is to evaluate the efficacy and safety of tumor necrosis factor (TNF) inhibitors BIOs as treatment for pediatric non-infectious uveitis (NIU).

METHODS

Data from pediatric patients with NIU treated with TNF inhibitors BIOs were drawn from the international AutoInflammatory Disease Alliance (AIDA) registries dedicated to uveitis and Behçet's disease. The effectiveness and safety of BIOs were assessed in terms of frequency of relapses, risk for developing ocular flares, best-corrected visual acuity (BCVA), glucocorticoids (GCs)-sparing effect, drug survival, frequency of ocular complications, and adverse drug event (AE).

RESULTS

Forty-seven patients (77 affected eyes) were enrolled. The BIOs employed were adalimumab (ADA) (89.4%), etanercept (ETA) (5.3%), and infliximab (IFX) (5.3%). The number of relapses 12 months prior to BIOs and at last follow-up was 282.14 and 52.43 per 100 patients/year. The relative risk of developing ocular flares before BIOs introduction compared to the period following the start of BIOs was 4.49 (95% confidence interval [CI] 3.38-5.98, p = 0.004). The number needed to treat (NNT) for ocular flares was 3.53. Median BCVA was maintained during the whole BIOs treatment (p = 0.92). A significant GCs-sparing effect was observed throughout the treatment period (p = 0.002). The estimated drug retention rate (DRR) at 12-, 24-, and 36-month follow-up were 92.7, 83.3, and 70.8%, respectively. The risk rate for developing structural ocular complications was 89.9/100 patients/year before starting BIOs and 12.7/100 patients/year during BIOs treatment, with a risk ratio of new ocular complications without BIOs of 7.1 (CI 3.4-14.9, p = 0.0003). Three minor AEs were reported.

CONCLUSIONS

TNF inhibitors BIOs are effective in reducing the number of ocular uveitis relapses, preserving visual acuity, allowing a significant GCs-sparing effect, and preventing structural ocular complications.

Anti-retinal Antibodies in Sarcoidosis

PURPOSE

To measure, characterize, and evaluate the clinical significance of anti-retinal antibodies in patients with sarcoid uveitis.

SUBJECTS/METHODS

Prospective study of anti-retinal antibodies in 45 patients with biopsy-proven sarcoidosis (25 with and 20 without uveitis). Results were compared with patients with confirmed infectious uveitis (n = 40) and non-infectious uveitis (n = 40).

RESULTS

Among sarcoidosis patients, anti-retinal antibodies were positive in 23/25 patients with uveitis and in 15/20 without uveitis [P = ns]. The most common antigens recognized were carbonic anhydrase II (14/23) and α-enolase (6/23). Anti-carbonic anhydrase II autoantibodies were infrequently detected in sarcoidosis patients without uveitis (2 out 15, P < .001), in patients with infectious uveitis (1 out 18, P < .001), and in patients with non-infectious uveitis (8 out 37, P < .001).

CONCLUSIONS

Anti-retinal antibodies recognizing carbonic anhydrase II are common in sarcoid uveitis. Although not fully sensitive and specific, they might be a useful non-invasive diagnostic tool for the diagnosis of sarcoid uveitis.

Knowledge and Current Practices in Monogenic Uveitis: An International Survey by IUSG and AIDA Network

INTRODUCTION

This study aims to explore awareness, knowledge, and diagnostic/therapeutic practices in monogenic uveitis (mU) among uveitis experts.

METHODS

This is an explorative, cross-sectional survey study. An anonymous, semi-structured, electronic survey was delivered to uveitis experts from the Autoinflammatory Diseases Alliance (AIDA) Network and International Uveitis Study Group (IUSG). We included respondents answering ≥ 50% of the survey.

RESULTS

Seventy-seven participants rated their knowledge of mU as proficient (3.9%), adequate (15.6%), sufficient (16.9%), or poor (63.6%). When asked about the first mU gene they thought of, 60.4% mentioned NOD2, 3.9% mentioned NLRP3 or MEFV, and 49.4% provided incorrect or no answers. Success rates in clinical scenarios varied from 15.6% to 55.8% and were higher for ophthalmologists working in multidisciplinary teams (p < 0.01). Genetic testing was ordered for suspected mU by 41.6% of physicians. The availability of molecular techniques did not significantly differ based on geography (p > 0.05). The public healthcare system ensured a higher percentage of tests prescribed were obtained by patients compared to private insurances (p < 0.00). In terms of disease-modifying anti-rheumatic drugs (DMARDs), tumor necrosis factor-α inhibitors were the most familiar to uveitis experts. The difficulties with off-label therapy procedures were the primary barrier to DMARDs prescription for patients with mU and correlated inversely with the obtained/prescribed drug ratio for interleukin-1 (p < 0.01) and interleukin-6 (p < 0.01) inhibitors.

CONCLUSIONS

This survey identifies proficiency areas, gaps, and opportunities for targeted improvements in patients care. The comprehensive outputs may inform evidence-based guidelines, empowering clinicians with standardized approaches, and drive an AIDA Network-IUSG unified effort to advance scientific knowledge and clinical practice.

Recovery course of persistent posterior subretinal fluid after successful repair of rhegmatogenous retinal detachment

PURPOSE

To investigate best corrected visual acuity (BCVA), subretinal fluid (SRF) absorption time or ellipsoid zone (EZ) restoration time and various variables in patients with persistent SRF after successful primary repair of rhegmatogenous retinal detachment (RRD).

METHODS

This retrospective multicenter study allowed independent analysis of the healing pattern by two observers based on composite of serial cross-sectional macular optical coherence tomography (OCT) scans. Univariate and multivariate analyses were implemented.

RESULTS

One hundred and three cases had persistent SRF after pars plana vitrectomy, scleral buckling, or pneumatic retinopexy. By univariate analysis, SRF resolution time correlated positively with the number of retinal breaks (p < 0.001) and with increased myopia (p = 0.011). Using multivariate analysis, final BCVA (log MAR) correlated positively with age, duration of RRD, initial BCVA (OR = 3.28; [95%CI = 1.44-7.47]; p = 0.015), and SRF resolution time (OR = 0.46 [95%CI 0.21-1.05]; p = 0.049). EZ restoration time was longer with increasing number of retinal tears (OR = 0.67; [95%CI 0.29-1.52]; p = 0.030), worse final BCVA, and presence of macula-off RRD (OR = 0.26; [95%CI 0.08-0.88]; p = 0.056). SRF resolution time correlated marginally with prone position.

CONCLUSIONS

Residual posterior SRF is more common in eyes with multiple breaks or in myopic eyes. Final BCVA is better in younger subjects and in eyes with shorter duration of RRD. Persistent SRF is a self-limited disorder with a mean resolution of 11.2 months with good visual prognosis improving from a mean baseline logMAR of 1.08 to 0.25 at one year.

Episcleritis and periorbital edema secondary to VEXAS syndrome

VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome is a newly described autoinflammatory entity caused by a UBA-1 gene mutation. Among the most frequent symptoms it produces fever, cytopenias, polychondritis, pulmonary infiltrates and up to 40% ocular involvement such as periorbital edema, uveitis, episcleritis, scleritis and retinal vasculitis. Patients respond to high doses of corticosteroids, however, many end up being refractory to them and to the classic immunosuppressants. We described the case of a 77-year-old male patient with ocular involvement in the form of episcleritis and periorbital edema who was later diagnosed with VEXAS Syndrome. The patient, after failing treatment with immunosuppressants, is currently receiving treatment with oral steroids and tocilizumab. Ophthalmologist must be aware of the ophthalmological affectation of autoinflammatory diseases and especially of this new entity described as the VEXAS Syndrome.

The retinal bacillary layer detachment: Clinical features and outcomes in posterior uveitis

PURPOSE

To describe the clinical characteristics, presentation and response to treatment in posterior uveitis patients with bacillary layer detachment (BLD) seen on optical coherence tomography (OCT).

MATERIALS AND METHODS

Retrospective review of patients with posterior uveitis and SD-OCT scans consistent with BLD. Data collected included demographics, uveitic etiology, treatment and duration of follow-up. Outcome measures included macular volume, central subfoveal thickness and visual acuity.

RESULTS

Sixteen patients (20 eyes) were included. Twelve were female (75%). The mean age was 43.68 ± 14.7 years. The most frequent etiology of the uveitis was Vogt-Koyanagi-Harada (VKH) disease (n=10), followed by sympathetic ophthalmia (n=2). BLD was bilateral in four patients. Eight patients were treated with intravenous methylprednisolone boluses. Immunosuppressive therapies were required in 8 patients. The mean follow-up was 70 months (range: 2.0-216.0).

CONCLUSION

BLD was observed in a series of posterior uveitis cases of various etiologies, showing functional and structural resolution with treatment in most cases.

Ocular involvement in adult and paediatric patients with monogenic autoinflammatory diseases: a Spanish multicentre retrospective study

OBJECTIVES

Ophthalmologic involvement in monogenic autoinflammatory diseases has been explored mainly in paediatric patients. The aim of this study is to characterise ophthalmologic manifestations, therapeutic management and visual outcomes in a Spanish (UVESAI) cohort of adult/paediatric patients with monogenic autoinflammatory diseases.

METHODS

Multicentre and retrospective study of patients with monogenic autoinflammatory diseases and ocular involvement. Eye manifestations, structural complications, treatments used and visual outcomes were analysed, and compared with previous studies.

RESULTS

Forty-six patients (44/2 adults/children; 21/25 adult/paediatric-onset) with monogenic autoinflammatory diseases [cryopyrin associated periodic syndromes (n=13/28.3%), mainly Muckle-Wells syndrome (MWS) (n=11/24%); familial Mediterranean fever (FMF) (n=12/26%); TNF receptor-associated periodic syndrome (TRAPS); (n=9/20%); Blau syndrome (n=8/17%); hyperimmunoglobulin D syndrome (HIDS) (n=2/4.3%), deficiency of adenosine deaminase-2 and NLRC4-Autoinflammatory disease] (one each) were included. Conjunctivitis (n=26/56.5%) and uveitis (n=23/50%) were the most frequent ocular manifestations. Twelve (26.1%) patients developed structural complications, being cataracts (n=11/24%) and posterior synechiae (n=10/22%) the most frequent. Conjunctivitis predominated in TRAPS, FMF, MWS and HIDS (mainly in adults), and uveitis, in Blau syndrome. Seven (8%) eyes (all with uveitis) presented with impaired visual acuity. Local and systemic treatment led to good visual outcomes in most patients. Compared with previous studies mainly including paediatric patients, less severe ocular involvement was observed in our adult/paediatric cohort.

CONCLUSIONS

Conjunctivitis was the most common ocular manifestation in our TRAPS, FMF, MWS and HIDS patients, and uveitis predominated in Blau syndrome. Severe eye complications and poor visual prognosis were associated with uveitis. Adults with monogenic autoinflammatory diseases seem to exhibit a less severe ophthalmologic presentation than paediatric patients.

Demystifying Ocular Syphilis - A Major Review

Syphilis, caused by the spirochaete, Treponema pallidum, continues to be a public health challenge globally with its rates steadily increasing in the past few years. The disease is transmitted through small breaks in the skin during sexual contact, or via congenital transmission in utero, either across the placenta or by contact with an active genital lesion during delivery. Estimated 5.7-6 million new cases are detected every year worldwide in the 15-49 years age group. An increased incidence has been reported in most populations with particular clusters in special groups like men who have sex with men, female sex workers, and their male clients. Ocular syphilis has a varied presentation and is considered a great mimicker in all cases of uveitis. The laboratory diagnosis of syphilis is predominantly based on serological tests including TPHA and VDRL. Parenteral penicillin is the cornerstone of treatment for all stages of ocular syphilis.

Herpetic Anterior Uveitis Multicentre Longitudinal Study (The UVHER Project). Baseline Characteristics

PURPOSE

The aim of the UVHER project is to evaluate the risk of development of optic nerve damage in patients with herpetic anterior uveitis (AU) prospectively followed over 2 years. Herein, we described the baseline characteristics.

METHODS

This is a multicentre, prospective study. An aqueous humour tap was performed. Only patients with a positive PCR were included. Clinical characteristics, optical coherence tomography (OCT) parameters and visual field (VF) abnormalities were registered.

RESULTS

27 patients were included: 18 Herpes Simplex (HSV), one Varicella Zoster (VVZ), and 8Cytomegalovirus (CMV). Patients with HSV-AU had severe inflammation, iris atrophy and corneal involvement. In patients with CMV-AU, less inflammation and medium-to-large keratic precipitates were observed. OCT showed a thinner RNFL and GCL in CMV-AU patients in comparison to HSV patients. VF showed abnormalities in six cases.

CONCLUSIONS

Patients in the UVHER cohort showed the typical clinical manifestations of herpetic AU. In CMV patients, optic nerve damage was observed at baseline, and in HSV patients, inflammation was more severe.

Efficacy and Safety of Adalimumab in Pediatric Non-infectious Non-anterior Uveitis: Real-life Experience From the International AIDA Network Uveitis Registry

INTRODUCTION

Scientific evidence of the effectiveness of the tumor necrosis factor inhibitor adalimumab (ADA) in pediatric patients with non-infectious non-anterior uveitis is still limited. The aim of this study is to investigate the therapeutic role of ADA in a cohort of pediatric patients with non-anterior uveitis.

METHODS

This is an international multicenter study analyzing real-life data referred to pediatric patients treated with ADA for intermediate uveitis/pars planitis, posterior uveitis and panuveitis. Data were drawn from the AutoInflammatory Disease Alliance (AIDA) registry for patients with uveitis.

RESULTS

Twenty-one patients (36 affected eyes) were enrolled, and all patients benefited from ADA administration. In detail, 11 patients (19 affected eyes) did not experience further ocular inflammation after ADA introduction; 10 cases (17 affected eyes) showed a significant clinical improvement consisting of a decrease in severity and/or frequency of ocular relapses. The number of ocular flares dropped from 3.91 to 1.1 events/patient/year after ADA introduction (p = 0.0009); macular edema and retinal vasculitis were respectively observed in 18 eyes and 20 eyes at the start of ADA and in 4 eyes and 2 eyes at the last assessment. The mean daily glucocorticoid dosage significantly decreased from 26.8 ± 16.8 mg/day at the start of ADA to 6.25 ± 6.35 mg/day at the last assessment (p = 0.002). Intermediate uveitis/pars planitis (p = 0.01) and posterior uveitis (p = 0.03) were more frequently observed in patients with full response to ADA; panuveitis (p = 0.001) was significantly more frequent among patients continuing to experience uveitic flares. This could be related to a higher use of systemic glucocorticoids (p = 0.002) and conventional immunosuppressants (p = 0.007) at the start of ADA when treating intermediate uveitis/pars planitis. Regarding the safety profile, only one adverse event was reported during ADA treatment, consisting of the development of generalized adenopathy.

CONCLUSIONS

ADA proved to have an effective therapeutic role in all pediatric patients with non-anterior uveitis enrolled in the study. An overall glucocorticoid-sparing effect was observed despite the severity of cases enrolled. A more aggressive treatment of panuveitis and posterior uveitis at start of ADA could increase the likelihood of full response to therapy.

A patient-driven registry on Behçet's disease: the AIDA for patients pilot project

Introduction

This paper describes the creation and preliminary results of a patient-driven registry for the collection of patient-reported outcomes (PROs) and patient-reported experiences (PREs) in Behçet's disease (BD).

Methods

The project was coordinated by the University of Siena and the Italian patient advocacy organization SIMBA (Associazione Italiana Sindrome e Malattia di Behçet), in the context of the AIDA (AutoInflammatory Diseases Alliance) Network programme. Quality of life, fatigue, socioeconomic impact of the disease and therapeutic adherence were selected as core domains to include in the registry.

Results

Respondents were reached via SIMBA communication channels in 167 cases (83.5%) and the AIDA Network affiliated clinical centers in 33 cases (16.5%). The median value of the Behçet's Disease Quality of Life (BDQoL) score was 14 (IQR 11, range 0-30), indicating a medium quality of life, and the median Global Fatigue Index (GFI) was 38.7 (IQR 10.9, range 1-50), expressing a significant level of fatigue. The mean Beliefs about Medicines Questionnaire (BMQ) necessity-concern differential was 0.9 ± 1.1 (range - 1.8-4), showing that the registry participants prioritized necessity belief over concerns to a limited extent. As for the socioeconomic impact of BD, in 104 out of 187 cases (55.6%), patients had to pay from their own pocket for medical exams required to reach the diagnosis. The low family socioeconomic status (p < 0.001), the presence of any major organ involvement (p < 0.031), the presence of gastro-intestinal (p < 0.001), neurological (p = 0.012) and musculoskeletal (p = 0.022) symptoms, recurrent fever (p = 0.002), and headache (p < 0.001) were associated to a higher number of accesses to the healthcare system. Multiple linear regression showed that the BDQoL score could significantly predict the global socioeconomic impact of BD (F = 14.519, OR 1.162 [CI 0.557-1.766], p < 0.001).

Discussion

Preliminary results from the AIDA for Patients BD registry were consistent with data available in the literature, confirming that PROs and PREs could be easily provided by the patient remotely to integrate physician-driven registries with complementary and reliable information.

Outcome Measures for Disease Monitoring in Intraocular Inflammatory and Infectious Diseases (OCTOMERIA): Understanding the Choroid in Uveitis with Optical Coherence Tomography (OCT)

PURPOSE

To compare imaging modalities for the choroid of the eye, and evaluate various choroidal changes in uveitides entities.

METHODS

A comprehensive systematic literature review was conducted looking at current imaging modalities available to assess choroid architecture and commonly used parameters available to qualify and quantify choroidal changes, before looking at specific uveitides entities with choroidal involvement which have been broadly separated into non-infectious and infectious in etiology.

RESULTS

We describe the various modalities currently available to evaluate the choroid of the eye such as Ultrasound B Scan, ICGA, and OCT. Choroidal changes in various ocular and systemic diseases such as Behcet's Disease, Sarcoidosis, Syphillis, Tuberculosis, and many more have been reported and published.

CONCLUSION

Multiple choroidal tomographic and angiotomographic findings have been demonstrated for evaluation in uveitis. These findings can manifest in multiple ocular and systemic diseases, and can be illustrated using the various imaging modalities at present. Future advancements in choroidal imaging would help to adapt these findings into parameters for clinical practice to properly evaluate these ocular and systemic diseases.

Clinical Features and Outcomes of Tubulointerstitial Nephritis and Uveitis Syndrome in Spain and Portugal: The IBERTINU Project

PURPOSE

To assess the clinical features, management and prognosis of patients diagnosed with tubulointerstitial nephritis and uveitis (TINU) syndrome in Spain and Portugal.

METHODS

Retrospective multicenter study, which included all patients diagnosed with TINU syndrome managed in 15 uveitis referral centers from Spain and Portugal.

RESULTS

Forty-eight subjects with a mean age at diagnosis of 25.0 [14.8; 49.5] years were included. Both eyes were affected in 43 patients (89.6%). The visual outcome was favorable, but immunosuppressive systemic therapy (IST) was needed in 26 (54.16%) due to relapses. Renal function normalized in 35 patients (72.9%). HLA-DQB1*05 was the most common genetic typing (57.1%). The mean follow-up time was 22.5 [11.0; 48.0] months.

CONCLUSIONS

Both visual and renal outcomes were favorable, although IST was frequently used. TINU is under- diagnosed, so further prospective studies would provide more knowledge about its recognition and management.

EXPERT OPINION

TINU Syndrome is underdiagnosed because ocular and renal disease are asynchronous. Outcomes are favorable so it has to be highly suspected in cases of bilateral anterior uveitis. According to literature and our experience, systemic immunosuppressive therapy is often required because of ocular relapses.This study adds to the previous knowledge that HLA-DQB1*05 could be an important HLA type amongst the TINU Syndrome Iberian population. HLA typing should be assessed in these patients in order to describe its phenotype-genotype relationship better. A considerable number of patients in our series were diagnosed in their sixties, so TINU Syndrome should also be suspected in elderly patients.

Spontaneous resolution of inflammatory epiretinal membrane: Case series and review of the literature

Epiretinal membrane (ERM) represents a common complication of uveitis that may contribute independently to vision loss in patients with uveitis. Although spontaneous idiopathic ERM separation has been previously reported, to the best of our knowledge there are only two case reports in the scientific literature that depicts spontaneous regression of an inflammation-associated ERM. Spontaneous ERM separation is a rare but possible event, which occurs most often subsequent to posterior vitreous detachment. We present a case series of three patients with uveitis that exhibit the formation and subsequent spontaneous resolution of an inflammatory ERM.

Central Retinal Vein Occlusion Presumably Associated with Lupus Anticoagulant Induced by SARSCoV-2

PURPOSE

To report a case of unilateral central retinal vein occlusion (CRVO) and macular edema presumably associated with lupus anticoagulant (LA) induced by severe acute respiratory syndrome coronavirus 2 (SARS CoV-2).

METHOD

Case report.

RESULTS

A 32-year-old male patient presented to the emergency department with a 5-day history of blurry vision. He was diagnosed with a CRVO and macular edema. The only pathological finding was positive LA which could have been induced by his recent confirmed SARS CoV-2 infection. The patient's evolution was satisfactory after two injections of Intravitreal dexamethasone (Ozurdex®), with improvement in macular edema and visual acuity.

CONCLUSION

COVID-19 may be associated to retinal vascular occlusive disorders. Transient virus-induced LA might play a role in the pathogenesis of the thrombotic event.

Guidance on brolucizumab management recommendations

PURPOSE

Brolucizumab, a new generation anti-VEGF, has demonstrated efficacy and safety in AMD in the pivotal HAWK and HARRIER trials. Post-marketing, previously undetected adverse events related to intraocular inflammation have been reported. An independent post hoc review of the pivotal trials puts the rate of IOI at 4.6%. The aim of this paper is to propose a set of recommendations for implementing the management of brolucizumab in clinical practice.

METHODS

The recommendations made by the authors are based on their clinical experience, critical review of (i) the pivotal trials, the post-hoc analysis of the Safety Review Committee, (ii), and (iii) the published literature.

RESULTS

In the pivotal trials, brolucizumab showed sustained functional gains, superior anatomical outcomes with potentially longer intervals between injections and a well-tolerated overall safety profile. Adverse events reported post-marketing include retinal vasculitis and retinal vascular occlusion. Based on the available information, experts recommend (i) ruling out non-recommended patient profiles (prior history of ORI), (ii) screening the patient prior to each injection to rule out active ORI, (iii) monitoring the patient for early warning signs, and (iv) treating immediately should any adverse events develop.

CONCLUSIONS

The adverse events reported are rare, but may be associated with severe and irreversible loss of visual acuity. The recommendations made are intended to facilitate the management of brolucizumab in the routine practice of retinologists, to ensure patient safety and, should any adverse events occur, to minimise their impact on vision.

Efficacy, safety and cost-effectiveness of methotrexate, adalimumab or their combination in non-infectious non-anterior uveitis: a protocol for a multicentre, randomised, parallel three arms, active-controlled, phase III open label with blinded outcome assessment study

INTRODUCTION

Non-infectious uveitis include a heterogeneous group of sight-threatening and incapacitating conditions. Their correct management sometimes requires the use of immunosuppressive drugs (ISDs), prescribed in monotherapy or in combination. Several observational studies showed that the use of ISDs in combination could be more effective than and as safe as their use in monotherapy. However, a direct comparison between these two treatment strategies has not been carried out yet.

METHODS AND ANALYSIS

The Combination THerapy with mEthotrexate and adalImumAb for uveitis (CoTHEIA) study is a phase III, multicentre, prospective, randomised, single-blinded with masked outcome assessment, parallel three arms with 1:1:1 allocation, active-controlled, superiority study design, comparing the efficacy, safety and cost-effectiveness of methotrexate, adalimumab or their combination in non-infectious non-anterior uveitis. We aim to recruit 192 subjects. The duration of the treatment and follow-up will last up to 52 weeks, plus 70 days follow-up with no treatment. The complete and maintained resolution of the ocular inflammation will be assessed by masked evaluators (primary outcome). In addition to other secondary measurements of efficacy (quality of life, visual acuity and costs) and safety, we will identify subjects' subgroups with different treatment responses by developing prediction models based on machine learning techniques using genetic and proteomic biomarkers.

ETHICS AND DISSEMINATION

The protocol, annexes and informed consent forms were approved by the Reference Clinical Research Ethic Committee at the Hospital Clínico San Carlos (Madrid, Spain) and the Spanish Agency for Medicines and Health Products. We will elaborate a dissemination plan including production of materials adapted to several formats to communicate the clinical trial progress and findings to a broad group of stakeholders. The promoter will be the only access to the participant-level data, although it can be shared within the legal situation.

CHARACTERIZING COVID-19-RELATED RETINAL VASCULAR OCCLUSIONS: A Case Series and Review of the Literature

PURPOSE

To describe clinical and ophthalmologic features and outcomes of patients with coronavirus disease-19 with retinal vascular occlusions.

METHODS

Retrospective multicenter case series and PubMed review of cases reported from March 2020 to September 2021. Outcome measures are as follows: type of occlusion, treatments, best-corrected visual acuity, and central macular thickness on optical coherence tomography.

RESULTS

Thirty-nine patients were identified. Fifteen patients with a median age of 39 (30-67) years were included in the multicenter study. Vascular occlusions included central retinal vein occlusion (12 eyes), branch retinal vein occlusion (4 eyes), and central retinal artery occlusion (2 eyes). Three cases were bilateral. Baseline best-corrected visual acuity was 20/45 (no light perception-20/20). Baseline central macular thickness was 348.64 (±83) μm. Nine eyes received anti-vascular endothelial growth factor agents, dexamethasone intravitreal implant, or both. Final best-corrected visual acuity was 20/25 (no light perception-20/20), and central macular thickness was 273.7 ± 68 μm (follow-up of 19.6 ± 6 weeks). Among the 24 cases from the literature review, retinal vein occlusion was the predominant lesion. Clinical characteristics and outcomes were similar to those found in our series.

CONCLUSION

Coronavirus disease-19-associated retinal vascular occlusions tend to occur in individuals younger than 60 years. Retinal vein occlusion is the most frequent occlusive event, and outcomes are favorable in most cases.

Vitreous and Optic Nerve Infiltration of an Adrenal B Lymphoma

Aim

This study aimed to report a case of vitreous and optic nerve infiltration of a primary adrenal B lymphoma.

Case Report

An 81-year-old patient consulted for decrease in vision in the left eye and pain with ocular movements during the last week. The patient was being treated with chemotherapy for an adrenal gland diffuse large B-cell lymphoma. On examination, vitritis was seen in both eyes and optic disc edema in his left eye. After an extensive study based on orbital and brain magnetic resonance imaging and vitreous cytology, an ocular infiltration by systemic B lymphoma was confirmed. A treatment based on intravitreal methotrexate was carried out, achieving the regression of the vitreous infiltration and resolution of the optic disc edema. Systemic B lymphoma metastasizing ocular structures is extremely infrequent. The manifestations may mimic an inflammatory disease. Ophthalmologists should be aware of these manifestations and consider among the masquerade syndromes.

Fluocinolone Implant for Idiopathic Retinal Vasculitis, Aneurysms, and Neuroretinitis Syndrome: A Case Report

Idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) syndrome is a rare and progressive disorder that predominantly affects both the eyes of young female individuals and can threaten visual function. Peripheral ischemia and macular exudation are common findings in patients. The treatment options include panretinal photocoagulation (PRP), systemic immunosuppression, and intravitreal antiangiogenic and corticosteroid therapy. Fluocinolone acetonide intravitreal implant is approved for the treatment of nonanterior noninfectious uveitis and diabetic macular edema (ME), with an estimated therapeutic duration of 3 years. We describe a case of IRVAN syndrome in a child with ME who had been previously treated with PRP, antiangiogenic therapy, and several dexamethasone intravitreal implants and received a fluocinolone acetonide intravitreal implant in her right eye. The patient showed stabilization of the visual acuity and a marked reduction of the macular thickness 1 month after the treatment. At 12-month follow-up, the patient required perifoveal focal photocoagulation due to a rebound of the ME. After 2 years of follow-up, visual acuity remains stable and macular retinal thickening under control. Local long-standing steroid therapy has proved to be quite efficient in controlling the progression of the disease in our patient.

AB0771 HIGH DOSE INTRAVENOUS METHYLPREDNISOLONE INDUCES RAPID IMPROVEMENT OF VISUAL ACUITY IN NON-INFECTIOUS UVEITIS OF DIFFERENT IMMUNE MEDIATED INFLAMMATORY DISEASES

Background:

Rapid and effective remission-inducing therapy is mandatory in uveitis to avoid irreversible structural and functional damage. In some severe cases biological agents might be required (1-6).

High-dose intravenous methylprednisolone (IVMP) may achieve prompt control of inflammation in most immune mediated inflammatory diseases (IMID), including non-infectious uveitis (NIU).

Objectives:

To evaluate the efficacy and safety of IVMP pulse therapy in NIU of different IMID.

Methods:

Multicentre study of 71 patients with severe uveitis who received IVMP. The underlying diseases were: Vogt Koyanagy Harada disease (VKHD) (n=24), Behçet disease (BD) (19), Sarcoidosis (5) and idiopathic NIU (23). The main outcome variable was Best-Corrected Visual Acuity (BCVA) estimated using the Snellen chart. BCVA that was assessed at 0 (basal), 2-5, 7, 15 and 30 days after IVMP.

The results are expressed as mean ±SD in normally distributed variables, or as median [IQR] when are not. Comparison of continuous variables was performed using the Wilcoxon test.

Results:

We studied 46♀/ 25♂ patients. The main features are shown in Table 1. IVMP dose ranged from 250 to 1000 mg/day administered for 3-5 consecutive days, the dose was established according to the presence or not of other systemic manifestations apart from uveitis. All of them had active intraocular inflammation at the moment of the study. BCVA values improved considerably after 1 month (Figure 1). No major side effects were observed.

Conclusion:

High-dose IVMP pulse therapy is useful and safe for a prompt control of BCVA regardless of the underlying IMID.

Impact of novel coronavirus infection in patients with uveitis associated with an autoimmune disease: Result of the COVID-19-GEAS patient survey

Introduction

The objective of these study is to know the characteristics of COVID-19 in patients with uveitis associated with Systemic Autoimmune Disease (SAD) through telematic survey.

Material and methods

Internal Medicine Society and Group of Systemic Autoimmune disease conducted a telematic survey of patients with SAD to learn about the characteristics of COVID-19 in this population.

Results

A total of 2,789 patients answered the survey, of which 28 had a diagnosis of uveitis associated with SAE. The majority (82%) were female and caucasian (82%), with a mean age of 48 years. The most frequent SAEs were Behçet’s disease followed by sarcoidosis and systemic lupus erythematosus. 46% of the patients were receiving corticosteroid treatment at a mean prednisone dose of 11 mg/day. Regarding infection, 14 (50%) patients reported symptoms compatible with SARS-CoV-2 infection. RT-PCR was performed on the nasopharyngeal smear in two patients and in one of them (4%) it was positive.

Conclusions

Both asymptomatic and symptomatic COVID-19 patients with ASD-associated UNI had received similar immunosuppressive treatment.

Multidisciplinary care and units for uveitis in the internal medicine departments in Spain: Survey of the Systemic Autoimmune Diseases Group

OBJECTIVE

To identify the multidisciplinary uveitis units in which internal medicine departments participate in collaboration with ophthalmology departments in Spain.

MATERIAL AND METHODS

We conducted a multicentre, observational cross-sectional study that collected information using a structured survey sent by email to 1015 partners of the Systemic Autoimmune Diseases Workgroup of the Spanish Society of Internal Medicine (GEAS-SEMI) from the 1st to the 31st of March 2017.

RESULTS

We identified a total of 21 support units/consultations for the ophthalmology departments. Seventeen (81%) of the units were specific internal medicine-ophthalmology consultations, and 5 (24%) units had been created in the past 5 years. A median of 460 patients were assessed per unit by the end of the year.

CONCLUSIONS

This study shows, for the first time in Spain, the important and close collaboration between ophthalmologists and internists, especially in highly specialised national reference institutions.

Plasma Rich in Growth Factors (PRGF) Increases the Number of Retinal Müller Glia in Culture but Not the Survival of Retinal Neurons

Plasma rich in growth factors (PRGF) is a subtype of platelet-rich plasma (PRP) that stimulates tissue regeneration and may promote neuronal survival. It has been employed in ophthalmology to achieve tissue repair in some retinal pathologies, although how PRGF acts in the retina is still poorly understood. As a part of the central nervous system, the retina has limited capacity for repair capacity following damage, and retinal insult can provoke the death of retinal ganglion cells (RGCs), potentially producing irreversible blindness. RGCs are in close contact with glial cells, such as Müller cells, that help maintain homeostasis in the retina. In this study, the aim was to determine whether PRGF can protect RGCs and whether it increases the number of Müller cells. Therefore, PRGF were tested on primary cell cultures of porcine RGCs and Müller cells, as well as on co-cultures of these two cell types. Moreover, the inflammatory component of PRGF was analyzed and the cytokines in the different PRGFs were quantified. In addition, we set out to determine if blocking the inflammatory components of PRGF alters its effect on the cells in culture. The presence of PRGF compromises RGC survival in pure cultures and in co-culture with Müller cells, but this effect was reversed by heat-inactivation of the PRGF. The detrimental effect of PRGF on RGCs could be in part due to the presence of cytokines and specifically, to the presence of pro-inflammatory cytokines that compromise their survival. However, other factors are likely to be present in the PRGF that have a deleterious effect on the RGCs since the exposure to antibodies against these cytokines were insufficient to protect RGCs. Moreover, PRGF promotes Müller cell survival. In conclusion, PRGF hinders the survival of RGCs in the presence or absence of Müller cells, yet it promotes Müller cell survival that could be the reason of retina healing observed in the in vivo treatments, with some cytokines possibly implicated. Although PRGF could stimulate tissue regeneration, further studies should be performed to evaluate the effect of PRGF on neurons and the implication of its potential inflammatory role in such processes.

The Effect of Plasma Rich in Growth Factors on Microglial Migration, Macroglial Gliosis and Proliferation, and Neuronal Survival

Plasma rich in growth factors (PRGF) is a subtype of platelet-rich plasma that has being employed in the clinic due to its capacity to accelerate tissue regeneration. Autologous PRGF has been used in ophthalmology to repair a range of retinal pathologies with some efficiency. In the present study, we have explored the role of PRGF and its effect on microglial motility, as well as its possible pro-inflammatory effects. Organotypic cultures from adult pig retinas were used to test the effect of the PRGF obtained from human as well as pig blood. Microglial migration, as well as gliosis, proliferation and the survival of retinal ganglion cells (RGCs) were analyzed by immunohistochemistry. The cytokines present in these PRGFs were analyzed by multiplex ELISA. In addition, we set out to determine if blocking some of the inflammatory components of PRGF alter its effect on microglial migration. In organotypic cultures, PRGF induces microglial migration to the outer nuclear layers as a sign of inflammation. This phenomenon could be due to the presence of several cytokines in PRGF that were quantified here, such as the major pro-inflammatory cytokines IL-1β, IL-6 and TNFα. Heterologous PRGF (human) and longer periods of cultured (3 days) induced more microglia migration than autologous porcine PRGF. Moreover, the migratory effect of microglia was partially mitigated by: 1) heat inactivation of the PRGF; 2) the presence of dexamethasone; or 3) anti-cytokine factors. Furthermore, PRGF seems not to affect gliosis, proliferation or RGC survival in organotypic cultures of adult porcine retinas. PRGF can trigger an inflammatory response as witnessed by the activation of microglial migration in the retina. This can be prevented by using autologous PRGF or if this is not possible due to autoimmune diseases, by mitigating its inflammatory effect. In addition, PRGF does not increase either the proliferation rate of microglial cells or the survival of neurons. We cannot discard the possible positive effect of microglial cells on retinal function. Further studies should be performed to warrant the use of PRGF on the nervous system.

Impact of novel coronavirus infection in patients with uveitis associated with an autoimmune disease: result of the COVID-19-GEAS patient survey

Introducción

El objetivo de este estudio es conocer las características de la COVID-19 en pacientes con uveítis asociada a enfermedades autoinmunes sistémicas (EAS) mediante una encuesta telemática.

Material y métodos

La Sociedad Española de Medicina Interna por medio del Grupo de Trabajo de Enfermedades Autoinmunes realizó una encuesta telemática a pacientes con EAS para conocer las características de la COVID-19 en esta población.

Resultados

Un total de 2.789 pacientes contestaron la encuesta, de los que 28 tenían un diagnóstico de uveítis asociada a una EAS. La mayoría (82%) eran mujeres y caucásicas (82%), con una media de 48 años. Las EAS más frecuentes fueron la enfermedad de Behçet seguida de la sarcoidosis y del lupus eritematoso sistémico. El 46% de los pacientes estaban recibiendo tratamiento con corticoides a una dosis media de prednisona de 11 mg/día. Respecto a la infección, 14 (50%) pacientes referían síntomas compatibles con infección por SARS-CoV-2. Se realizó RT-PCR en el frotis nasofaríngeo en dos pacientes y en uno de ellos (4%) fue positivo.

Conclusiones

Los pacientes con UNI asociada a EAS tanto los asintomáticos como los sintomáticos de COVID-19 habían recibido de forma similar tratamiento inmunosupresor.

Paraneoplastic Focal Outer Retinitis and Optic Neuropathy in a Patient with Small Cell Lung Carcinoma and Anti-CRMP5, Anti-HU and Anti-Amphiphysin Antibodies

Our aim is to describe clinical and optical coherence tomographic features of acute paraneoplastic focal outer retinitis associated with optic neuropathy in a patient diagnosed with small cell lung carcinoma. Bilateral focal outer retinitis, bilateral optic disc oedema and vitritis were identified in a patient with progressive bilateral visual loss and ataxia. Spectral domain optical coherence tomography (SD-OCT) revealed various extents of granular hyperreflectivity and atrophy of the macular outer retinal layers. Serum and cerebrospinal fluid positivity for anti-CRMP5, anti-HU and anti-amphiphysin antibodies intensified the search for an underlying malignancy, and a small cell lung carcinoma (SCLC) was finally diagnosed. Local and oral steroids along with systemic chemotherapy and radiotherapy achieved cancer remission and partial recovery from the ophthalmic manifestations. Focal outer retinitis associated with optic disc oedema and antibody positivity facilitated the diagnosis of SCLC in a localized stage. SD-OCT allowed the characterization of this entity, expanding the spectrum of paraneoplastic ophthalmological syndromes.

Systemic Regulatory T Cells and IL-6 as Prognostic Factors for Anatomical Improvement of Uveitic Macular Edema

Purpose

To investigate whether systemic immune mediators and circulating regulatory T cells (Tregs) could be prognostic factors for anatomic outcomes in macular edema secondary to non-infectious uveitis (UME).

Methods

Multicenter, prospective, observational, 12-month follow-up study of 60 patients with UME. Macular edema was defined as central subfield thickness (CST) > 300 μm measured with spectral domain optical coherence tomography (SD-OCT). Serum samples and peripheral blood mononuclear cells (PBMC) were obtained from venous blood extraction at baseline. Serum levels of IL-1β, IL-6, IL-8, IL-17, MCP-1, TNF-α, IL-10, and VEGF were determined by Luminex. Tregs population, defined as CD3⁺CD4⁺FoxP3⁺ in PBMC, was determined by flow cytometry. Main outcome measure was the predictive association between searched mediators and CST sustained improvement, defined as CST < 300 microns or a 20% CST decrease, at 6 months maintained until 12-months compared to baseline levels.

Results

Multivariate logistic regression analysis showed an association between CST sustained improvement at 12 months follow-up and IL-6 and Tregs baseline levels. Higher IL-6 levels were associated with less events of UME improvement (OR: 0.67, 95% CI (0.45–1.00), P = 0.042), whereas higher levels of Tregs favored such improvement (OR: 1.25, 95% CI: 1.12–2.56, P = 0.049).

Conclusions

Increased levels of Tregs and reduced levels of IL-6 in serum may be prognostic factors of sustained anatomical improvement in UME. These findings could enforce the opportunity to develop more efficient and personalized therapeutic approaches to improve long-term visual prognosis in patients with UME.

Adalimumab in Elderly Patients with Non-Infectious Uveitis. Safety and Efficacy

PURPOSE

To assess the efficacy and safety of adalimumab in elderly patients with noninfectious uveitis (NIU).

METHODS

An observational, retrospective, multicenter study was done. Changes in best-corrected visual acuity (BCVA), inflammatory activity parameters, central retinal thickness (CRT), and the occurrence of adverse events (AE) developed during follow-up were recorded.

RESULTS

A total of 82 eyes from 41 patients 60 years of age and older with noninfectious uveitis treated with adalimumab were included. A significant improvement in BCVA (71.5 to 75.4 letters, p = .001) and in CRT (311.1 μm to 265 μm, p = .001) was observed. Moreover, a significant decrease from baseline in the rate of patients with anterior chamber cell (ACC) >0+ (34.6% to 5.7%, p = <0.001) or vitreous haze>0+ (21.3% to 4.3%, p = .002) was determined. AEs were observed in 11 patients (26.8%).

CONCLUSION

Adalimumab can be safe and efficacious for the treatment of NIU in patients 60 years of age and older.

Effect of somatostatin on human retinal pigment epithelial cells permeability

PURPOSE

To assess the effect of somatostatin (SST) on the permeability of human retinal pigment epithelial cells.

METHODS

We conducted two experiments, exposing cells from human-fetal retinal pigment epithelium (hfRPE) cultures to vascular endothelial growth factor (VEGF), with or without SST pretreatment, in one, and to hypoxic conditions, again with or without SST pretreatment, in the other. The paracellular permeability of hfRPE was assessed by measuring transepithelial electrical resistance (TER) and fluorescein isothiocyanate-sodium (FITC-sodium) flux. Immunochemistry analysis was used to assess the expression of occludin and Zonula occludens-1(ZO-1).

RESULTS

Both VEGF and hypoxia increased permeability of the hfRPE, as measured by TER and tracer flux, and decreased occludin and ZO-1staining, as measured by immunochemistry. Pretreatment of cultures with SST partially counteracted these effects.

CONCLUSIONS

Somatostatin may play a role in the regulation of permeability across retinal pigment epithelium. It may act as an anti-permeability factor in the retina through the enhancement of tight junction function.

Evolution of retinal changes measured by optical coherence tomography in the assessment of hydroxychloroquine ocular safety in patients with systemic lupus erythematosus

OBJECTIVE

The objective of this report is to analyse retinal changes over a five-year period, assessed by spectral domain-optical coherence tomography (SD-OCT), in patients from the Lupus-Cruces cohort treated with hydroxychloroquine (HCQ).

METHODS

SD-OCT screening was performed annually between 2012 and 2017. Average macular thickness (AMT), ganglion cell layer thickness (GCLT) and qualitative data of retinal pigment epithelium (RPE) and external retina (ExtR) were collected prospectively. We compared data from 2012 (first) and 2017 (second) SD-OCT.

RESULTS

We studied 110 patients and 195 eyes. No cases of HCQ toxicity were detected. At the time of the second SD-OCT, 99% patients had taken a daily dose of HCQ ≤5 mg/kg/day. The median time on HCQ was 133 months. The mean AMT and GCLT were significantly lower in both eyes at the second SD-OCT; however, all the differences were clinically insignificant at less than 1%. Qualitative analysis of RPE and ExtR showed no significant changes. Similar results were found among patients with risk factors for retinopathy. The comparison of patients with and without risk factors showed no differences.

CONCLUSIONS

This study shows clinically irrelevant retinal changes in an SLE cohort on HCQ treatment over a five-year follow-up. Our findings support the safety of long-term HCQ at doses ≤5 mg/kg/day.

Predictors for functional and anatomic outcomes in macular edema secondary to non-infectious uveitis

Aims

We aimed to investigate predictive factors for visual and anatomic outcomes in patients with macular edema secondary to non-infectious uveitis.

Material and methods

We conducted a multicenter, prospective, observational, 12-month follow-up study. Participants included in the study were adults with non-infectious uveitic macular edema (UME), defined as central subfoveal thickness (CST) of >300 μm as measured by spectral domain optical coherence tomography (SD-OCT) and fluid in the macula. Demographic, clinical and tomographic data was recorded at baseline, 1, 3, 6 and 12 months. Foveal-centered SD-OCT exploration was set as the gold-standard determination of UME using a standard Macular Cube 512x128 A-scan, within a 6 x 6 mm² area, and the Enhanced High Definition Single-Line Raster. To assess favorable prognosis, the main outcomes analyzed were the best-corrected visual acuity (BCVA) and the CST. Favorable prognosis was defined as sustained improvement of BCVA (2 lines of gain of the Snellen scale) and CST (decrease of 20% of the initial value or <300 μm) within a 12 month period.

Results

Fifty-six eyes were analyzed. The number of eyes with sustained improvement in the CST was 48 (86.2%), against 23 (41.1%) eyes with sustained improvement in BCVA. Favorable prognosis, as defined above, was observed in 18 (32.1%) eyes. UME prognosis was negatively correlated with baseline foveal thickening, alteration in the vitreo-macular interface and cystoid macular edema. In contrast, bilaterally, systemic disease and the presence of anterior chamber cells were predictive of favorable prognosis.

Conclusion

Available treatment modalities in UME may avoid chronic UME and improve anatomic outcome. However, the proportion of functional amelioration observed during 12 months of follow-up is lower. Thicker CST, alteration in the vitreo-macular interface and cystoid macular edema may denote less favorable prognosis. Conversely, bilaterally, systemic disease and anterior chamber cells may be associated with favorable prognosis in UME.

Dexamethasone protects retinal ganglion cells but not Müller glia against hyperglycemia in vitro

Diabetic retinopathy (DR) is a common complication of diabetes, for which hyperglycemia is a major etiological factor. It is known that retinal glia (Müller cells) and retinal ganglion cells (RGCs) are affected by diabetes, and there is evidence that DR is associated with neural degeneration. Dexamethasone is a glucocorticoid used to treat many inflammatory and autoimmune conditions, including several eye diseases like DR. Thus, our goal was to study the effect of dexamethasone on the survival of RGCs and Müller glial cells isolated from rat retinas and maintained in vitro under hyperglycemic conditions. The behavior of primary RGC cell cultures, and of mixed RGC and Müller cell co-cultures, was studied in hyperglycemic conditions (30 mM glucose), both in the presence and absence of Dexamethasone (1 μM). RGC and Müller cell survival was evaluated, and the conditioned media of these cultures was collected to quantify the inflammatory cytokines secreted by these cells using a multiplex assay. The role of IL-1β, IL-6 and TNFα in RGC death was also evaluated by adding these cytokines to the co-cultures. RGC survival decreased significantly when these cells were grown in high glucose conditions, reaching 54% survival when they were grown alone and only 33% when co-cultured with Müller glia. The analysis of the cytokines in the conditioned media revealed an increase in IL-1β, IL-6 and TNFα under hyperglycemic conditions, which reverted to the basal concentration in co-cultures maintained in the presence of dexamethasone. Finally, when these cytokines were added to co-cultures they appeared to have a direct effect on RGC survival. Hence, these cytokines could be implicated in the death of RGCs when glucose concentrations increase and dexamethasone might protect RGCs from the cell death induced in these conditions.

Efficacy and Safety of an Aflibercept Treat-and-Extend Regimen in Treatment-Naïve Patients with Macular Oedema Secondary to Central Retinal Vein Occlusion (CRVO): A Prospective 12-Month, Single-Arm, Multicentre Trial

OBJECTIVES

To evaluate efficacy and safety of an aflibercept treat-and-extend (TAE) regimen in patients with macular oedema (MO) secondary to central retinal vein occlusion (CRVO).

DESIGN SETTING AND PATIENTS

Phase IV, prospective, open-label, single-arm trial in 11 Spanish hospitals. Treatment-naïve patients with <6 month diagnosis of MO secondary to CRVO and best-corrected visual acuity (BCVA) of 73-24 ETDRS letters were included between 23 January 2015 and 17 March 2016.

INTERVENTION

Intravitreal aflibercept 2 mg monthly (3 months) followed by proactive individualized dosing.

MAIN OUTCOMES

Mean change in BCVA after 12 months.

RESULTS

24 eyes (24 patients) were included; mean (SD) age: 62.8 (15.0) years; 54.2% male; median (IQR) time since diagnosis: 7.6 (3.0, 15.2) days. Mean BCVA scores significantly improved between baseline (56.0 (16.5)) and Month 12 (74.1 (17.6)); mean (95% CI) change: 14.8 (8.2, 21.4); P=0.0001. Twelve (50.0%) patients gained ≥15 ETDRS letters. Foveal thickness improved between baseline (mean: 569.4 (216.8) µm) and Month 12 (mean 257.4 (48.4) µm); P < 0.0001. At Month 12, 8.3% patients had MO. The mean (SD) number of injections: 8.3 (3.0). No treatment-related AEs were reported. Five (20.8%) patients experienced ocular AEs. Two nonocular serious AEs were reported.

CONCLUSIONS

An aflibercept TAE regimen improves visual acuity in patients with MO secondary to CRVO over 12 months with good tolerability.

Dabrafenib for cutaneous melanoma infiltrating the vitreous: regression of metastasis and occurrence of uveitis as a secondary effect

Intraocular metastasis of cutaneous melanoma is extremely infrequent. This typically occurs in advanced metastatic disease and has a poor survival prognosis. The most frequent reported treatment is radiotherapy. BRAF inhibitors are new, orally administered and very effective drugs used for metastatic cutaneous melanoma. Herein, we report a case of a 58-year-old patient with a recent diagnosis of cutaneous melanoma who consulted for floaters and presented vitreous opacities in both eyes. A diagnostic vitrectomy of his left eye was performed and pathologic analysis disclosed infiltrating melanoma cells in the vitreous. Treatment with dabrafenib (a type of BRAF inhibitor) achieved the regression of the intraocular metastasis in the right eye. Moreover, the patient presented a severe anterior uveitis due to dabrafenib, a well-known secondary effect of this drug.

Development of an activity disease score in patients with uveitis (UVEDAI)

To develop a disease activity index for patients with uveitis (UVEDAI) encompassing the relevant domains of disease activity considered important among experts in this field. The steps for designing UVEDAI were: (a) Defining the construct and establishing the domains through a formal judgment of experts, (b) A two-round Delphi study with a panel of 15 experts to determine the relevant items, (c) Selection of items: A logistic regression model was developed that set ocular inflammatory activity as the dependent variable. The construct “uveitis inflammatory activity” was defined as any intraocular inflammation that included external structures (cornea) in addition to uvea. Seven domains and 15 items were identified: best-corrected visual acuity, inflammation of the anterior chamber (anterior chamber cells, hypopyon, the presence of fibrin, active posterior keratic precipitates and iris nodules), intraocular pressure, inflammation of the vitreous cavity (vitreous haze, snowballs and snowbanks), central macular edema, inflammation of the posterior pole (the presence and number of choroidal/retinal lesions, vascular inflammation and papillitis), and global assessment from both (patient and physician). From all the variables studied in the multivariate model, anterior chamber cell grade, vitreous haze, central macular edema, inflammatory vessel sheathing, papillitis, choroidal/retinal lesions and patient evaluation were included in UVEDAI. UVEDAI is an index designed to assess the global ocular inflammatory activity in patients with uveitis. It might prove worthwhile to motorize the activity of this extraarticular manifestation of some rheumatic diseases.

Dexamethasone intravitreal implants in the management of tubercular multifocal serpiginoid choroiditis

Background

Continuous progression of lesions despite an adequate treatment has been described in tubercular multifocal serpiginoid choroiditis. Reported treatments for this paradoxical response include systemic steroids, immunosuppressive drugs, and intravitreal methotrexate. We describe the use of dexamethasone intravitreal implants in a patient presenting with this condition.

Findings

A 46-year-old woman sought medical attention for scotomas in her left eye. Tests suggested multifocal serpiginoid choroiditis associated with latent tuberculosis infection, and hence, she was started on anti-tuberculosis drugs in combination with corticosteroids. Given that lesions progressed despite this treatment, we began treatment with dexamethasone intravitreal implants. After injection of the second implant, we succeeded in inactivating the inflammatory process.

Conclusions

Dexamethasone intravitreal implants may be a suitable alternative to systemic steroids or immunosuppressive therapy in the management of continuous progression of lesions in tubercular multifocal serpiginoid choroiditis.
