RESUMO

BACKGROUND: Non-infectious uveitis affecting the posterior segment of the eye (NIU-PS) is an inflammatory disease, which can significantly impair visual acuity if not adequately treated. Fluocinolone-acetonide sustained-release-0.2 µg/day intravitreal (FAc) implants are indicated for prevention of relapse in recurrent NIU-PS. The aim here was to provide treating clinicians with some consensus-based-recommendations for the clinical management of patients with NIU-PS with 0.2 µg/day FAc implants. METHODS: A European-clinical-expert-group agreed to develop a consensus report on different issues related to the use of FAc implants in patients with NIU-PS. RESULTS: The Clinical-expert-panel provided specific recommendations focusing on clinical presentation (unilateral/bilateral) of the NIU-PS; systemic involvement of NIU-PS and the lens status. Treatment algorithms were developed; one that refers to the management of patients with NIU-PS in clinical practice and another that establishes the best clinical scenarios for the use of FAc implants, both as monotherapy and as adjuvant therapy. Additionally, the Clinical-expert-panel has provided recommendations about the use of the FAc implants in a clinical-setting. The Clinical-expert-panel also considered the safety profile of FAc implants and their possible implications in the daily practice. CONCLUSIONS: As more clinical experience has been gained using FAc implants, it was necessary to update the clinical recommendations that guide patient management in the clinic. The current consensus document addresses relevant issues related to the use of FAc implants on different types of patients with various etiologies of NIU-PS, and was conducted to standardize approaches to help specialists obtain better clinical outcomes.

RESUMO

Age-related macular degeneration, a multifactorial inflammatory degenerative retinal disease, ranks as the leading cause of blindness in the elderly. Strikingly, there is a scarcity of curative therapies, especially for the atrophic advanced form of age-related macular degeneration, likely due to the lack of models able to fully recapitulate the native structure of the outer blood retinal barrier, the prime target tissue of age-related macular degeneration. Standard in vitro systems rely on 2D monocultures unable to adequately reproduce the structure and function of the outer blood retinal barrier, integrated by the dynamic interaction of the retinal pigment epithelium, the Bruch's membrane, and the underlying choriocapillaris. The Bruch's membrane provides structural and mechanical support and regulates the molecular trafficking in the outer blood retinal barrier, and therefore adequate Bruch's membrane-mimics are key for the development of physiologically relevant models of the outer blood retinal barrier. In the last years, advances in the field of biomaterial engineering have provided novel approaches to mimic the Bruch's membrane from a variety of materials. This review provides a discussion of the integrated properties and function of outer blood retinal barrier components in healthy and age-related macular degeneration status to understand the requirements to adequately fabricate Bruch's membrane biomimetic systems. Then, we discuss novel materials and techniques to fabricate Bruch's membrane-like scaffolds for age-related macular degeneration in vitro modeling, discussing their advantages and challenges with a special focus on the potential of Bruch's membrane-like mimics based on decellularized tissue.

RESUMO

PURPOSE: The purpose of the study was to identify non-invasive imaging biomarkers potentially useful for close activity monitoring in birdshot chorioretinitis (BSCR). METHODS: Cross-sectional study of BSCR eyes included as per Levinson's and/or SUN criteria. Eyes were blindly classified into active or inactive groups per clinical inflammatory parameters, ultra-widefield (UWF) pseudocolour images, UWF fluorescein angiography (FA) and macular optical coherence tomography (OCT) cube. Qualitative and quantitative OCT and OCT-angiography (OCT-A) parameters at the fundus, superonasal and inferonasal fields were compared between active and inactive eyes. RESULTS: Thirty consecutive BSCR patients (60 eyes) were analysed. 28 eyes (46.66%) were from women and the overall mean age was 59.7 ± 12.3 years. Active eyes showed an abnormal retinal thickening at inferonasal field (nasal retinal thickness) and a higher averaged thickened retinal index (ATRI) (72.36 active vs. 20.12 inactive, p < 0.0001). A significant moderate correlation was observed between ATRI and FA scores (r = 0.259, p = 0.022). Macular vascular loops were more frequent in the superficial vascular plexus of OCT-A in the active eyes (p = 0.028). The vascular perfusion index tended to be higher in all subfields of active eyes but did not reach statistical significance. CONCLUSION: Multimodal imaging could be key to discerning activity in BSCR eyes. Higher ATRI and the presence of vascular loops in the superficial plexus are potential non-invasive activity biomarkers for the close monitoring of BSCR.

RESUMO

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.

RESUMO

PURPOSE: This study assessed the effectiveness of the 0.19-mg fluocinolone acetonide (FAc) implant by multimodal measurements in patients with non-infectious uveitis (NIU) in a real-world setting in Spain. METHODS: A prospective study of patients who had NIU including uveitic macular oedema (UME) with ≥ 12 months follow-up was done. Exclusion criteria include infectious uveitis and uncontrolled glaucoma or ocular hypertension requiring more than 2 medications. Effectiveness was assessed using a multicomponent outcome measure that included nine outcomes. Effectiveness was defined as all components being met at every timepoint. Secondary outcome measures were onset or progression of glaucoma and investigator-reported adverse events. RESULTS: Twenty-six eyes from 22 patients were included, with 96.2% having an indication including UME. During the 12-month study, the FAc implant was effective in 15 (57.7%) eyes, reaching effectiveness as soon as 2 weeks post-implantation. Mean best-corrected visual acuity and mean central macular thickness (CMT) were significantly improved vs. baseline at all timepoints (all comparisons p < 0.01). During the 12-month study, inflammation markers (anterior chamber cells and vitreous haze) had also significantly declined. Factors predicting effectiveness at month 12 were systemic corticosteroid dose pre-FAc, higher immunomodulatory therapy (IMT) load at baseline and thicker retinal nerve fibre layer (RNFL) at baseline (all p < 0.05). Factors predicting failure were male gender, thinner RNFL at baseline and treatment ineffectiveness at 1 month (all p < 0.05). In parallel, corticosteroid and IMT use also declined significantly. No significant increase in IOP was detected. CONCLUSION: The FAc implant is safe and effective at treating NIU over 12 months in a real-world setting in Spain.

RESUMO

Therapeutic approaches for noninfectious uveitis have expanded greatly over the past 10 years, but are limited by potential side effects and limited efficacy. Thus, therapeutic approaches that include less toxic, potentially preventative strategies to manage noninfectious uveitis are essential areas of study. Diets rich in fermentable fiber are potentially preventative in various conditions such as metabolic syndrome and type 1 diabetes. We studied the effects of various fermentable dietary fibers in an inducible model of experimental autoimmune uveitis (EAU) and found that they differentially modulated uveitis severity. A high pectin diet was the most protective, reducing clinical disease severity through the induction of regulatory T lymphocytes and the suppression of Th1 and Th17 lymphocytes at peak ocular inflammation in either intestinal or extra-intestinal lymphoid tissues. The high pectin diet also promoted intestinal homeostasis as shown by changes in intestinal morphology and gene expression, as well as intestinal permeability. Pectin-induced modulation of intestinal bacteria appeared to be associated with protective changes in immunophenotype in the intestinal tract, and correlated with reduced uveitis severity. In summary, our current findings support the potential for dietary intervention as a strategy to mitigate noninfectious uveitis severity.

RESUMO

AIMS: To evaluate the clinical characteristics and therapeutic outcome of patients with recurrent scleritis of unknown demonstrable aetiology and positive QuantiFERON-TB Gold In-Tube test (QFT). METHODS: Retrospective chart review of the demographic, clinical, laboratory and therapeutic outcome data of 15 patients. Clinical characteristics as well as remission rate after standard antituberculous therapy (ATT) were assessed. RESULTS: There were 9 men and 6 women with a mean age of 48.9 years (range, 32-73). Scleritis was diffuse in 10 patients (66.6%) and nodular in 5 patients (33.3%), 1 of them with concomitant posterior scleritis. It was bilateral in 7 patients (46.6%) and recurrent in all of them. Scleritis appeared after prior uveitis (10 patients, 66.6%) and/or with concomitant uveitis (5 patients, 33.3%) or peripheral keratitis (5 patients, 33.3%). Previous ocular surgery was found in 7 patients (46.6%). Previous extraocular tuberculosis (TB) infection or previous TB contact was detected in 11 patients (73.3%). No radiologic findings of active extraocular TB were detected. ATT was used in 15 patients, sometimes with the addition of systemic corticosteroids (5 patients) and methotrexate (1 patient); 14 patients achieved complete remission (93.3%). CONCLUSION: Presumed TB-related scleritis may appear in recurrent scleritis of unknown origin and positive QFT. It may occur after prior uveitis and/or concomitantly with uveitis or peripheral keratitis, and it may be triggered by previous ocular surgery. No patients had evidence of concurrent active extraocular infection, although many had previous TB infection or TB contact. ATT was effective, sometimes with the addition of systemic corticosteroids and methotrexate.

RESUMO

PURPOSE: To describe clinical features including multimodal imaging in a case of diffuse subretinal fibrosis and uveitis syndrome. METHODS: A young patient presented with counting fingers in both eyes due to posterior uveitis and unresponsive to systemic corticosteroids. Ultra-wide field pseudo-color and autofluorescence imaging, optical coherence tomography angiography (OCT-A), en-face OCT-A, and spectral-domain optical coherence were performed. RESULTS: Clinical examination revealed a bilateral fibrosis plaque in both fovea and macular multifocal choroidal lesions associated, with no vitritis. Ultra-wide field-autofluorescence allowed us to determine activity showing a hyperfluorescent pattern. En-face OCT-A at the level of the ellipsoid layer showed multiple hyperreflective lesions surrounding a hyperreflective fibrosis plaque in both eyes, which improved and stabilized during the follow-up. Optical coherence tomography angiography at the level of retina pigmentary epithelium-choriocapillaris revealed neocapillary network changes along the chronification of the disease. The patient required the addition of intravitreal dexamethasone implants (Ozurdex) to control the acute rebounds and anti-TNFα to control the underlying inflammatory process. CONCLUSION: This is the first diffuse subretinal fibrosis with uveitis syndrome reported with a complete En-face OCT-A and OCT-A examination. This multi-modal imaging will improve the monitoring of the disease's activity and the chronicity changes.

RESUMO

Uveitis consists of a group of syndromes characterised by intraocular inflammation, accounting for up to 15% of visual loss in the western world and 10% worldwide. Assessment of intraocular inflammation has been limited to clinician-dependent, subjective grading. Developments in imaging technology, such as optical coherence tomography (OCT), have enabled the development of objective, quantitative measures of inflammatory activity. Important quantitative metrics including central macular thickness and vitreous signal intensity allow longitudinal monitoring of disease activity and can be used in conjunction with other imaging modalities enabling holistic assessment of ocular inflammation. Ongoing work into the validation of instrument-based measures alongside development of core outcome sets is crucial for standardisation of clinical trial endpoints and developing guidance for quantitative multi-modal imaging approaches. This review outlines methods of grading inflammation in the vitreous and retina, with a focus on the use of OCT as an objective measure of disease activity.

RESUMO

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.

RESUMO

In the last decades, personalized medicine has been increasing its presence in different fields of medicine, including ophthalmology. A new factor that can help us direct medicine towards the challenge of personalized treatments is the microbiome. The gut microbiome plays an important role in controlling immune response, and dysbiosis has been associated with immune-mediated diseases such as non-infectious uveitis (NIU). In this review, we gather the published evidence, both in the pre-clinical and clinical studies, that support the possible role of intestinal dysbiosis in the pathogenesis of NIU, as well as the modulation of the gut microbiota as a new possible therapeutic target. We describe the different mechanisms that have been proposed to involve dysbiosis in the causality of NIU, as well as the potential pharmacological tools that could be used to modify the microbiome (dietary supplementation, antibiotics, fecal microbiota transplantation, immunomodulators, or biologic drugs) and, consequently, in the control of the NIU. Furthermore, there is increasing scientific evidence suggesting that the treatment with anti-TNF not only restores the composition of the gut microbiota but also that the study of the composition of the gut microbiome will help predict the response of each patient to anti-TNF treatment.

RESUMO

Purpose: The purpose of this study was to investigate the effect of antimetabolite drugs on T-cell responses and intestinal microbial composition in autoimmune uveitis. Methods: Experimental autoimmune uveitis (EAU) was induced in C57BL/6J mice treated with 0.00625 mg/mL methotrexate (MTX) or 0.625 mg/mL mycophenolate mofetil (MMF) in drinking water for 4 weeks prior to immunization and 2 weeks thereafter. The effector T cell (Teff) and regulatory T cell (Treg) populations were identified using flow cytometry. The 16S rRNA gene sequencing was applied for gut microbiome characterization. DESeq2 analysis was used to discriminate relative abundances of taxa and PLS-DA to integrate cytometric and microbiome data between groups. Results: Both MTX and MMF abrogated uveitis in EAU without clinical signs of toxicity as compared to water-fed controls. MTX reduced Teff and Treg expansion in peripheral tissues and eyes. MTX decreased alpha diversity, increased Akkermansia, and reduced Lachnoclostridium abundances. Conversely, MMF enhanced Tregs in the mesenteric lymph node and the eyes. In parallel, MMF increased the gut alpha diversity, including an increased abundance of Lachnospiraceae NK4A136 group and a decreased abundance of Lachnospiraceae UCG-001. A significant congruent correlation among intestinal microbial changes, T-cell responses, and clinical scores was observed for both antimetabolites. Conclusions: Although MTX and MMF both abrogated uveitis in EAU, they showed different effects on T-cell subsets and the intestinal bacterial composition. This work indicates unique immunomodulation by each drug and is the first to demonstrate potential microbiota-related mechanisms.

RESUMO

C-reactive protein (CRP), an active regulator of the innate immune system, has been related to COVID-19 severity. CRP is a dynamic protein undergoing conformational changes upon activation in inflammatory microenvironments between pentameric and monomeric isoforms. Although pentameric CRP is the circulating isoform routinely tested for clinical purposes, monomeric CRP shows more proinflammatory properties. Therefore, we aimed to determine the potential of monomeric CRP in serum as a biomarker of disease severity in COVID-19 patients (admission to intensive care unit [ICU] and/or in-hospital mortality). We retrospectively determined clinical and biological features as well as pentameric and monomeric CRP levels in a cohort of 97 COVID-19 patients within 72h of hospital admission. Patients with severe disease had higher levels of both pentameric and monomeric CRP. However, multivariate analysis showed increased mCRP but not pCRP to be independently associated to disease severity. Notably, mCRP levels higher than 4000 ng/mL (OR: 4.551, 95% CI: 1.329-15.58), together with number of co-morbidities, low lymphocyte count, and procalcitonin levels were independent predictors of disease severity in the multivariate model. Our results show the potential of mCRP levels as a marker of clinical severity in COVID-19 disease.

RESUMO

PURPOSE: Anti-TNF-α-induced lupus (ATIL) is a rare condition considered as a drug-induced lupus (DIL) in patients under anti-TNF-α therapies. Nowadays it is still unclear if ATIL is a classical DIL or represent a distinct syndrome. Some characteristics of DIL have been described specifically associated with patients with lupus-like syndrome receiving anti-TNF-α therapy: the severity of the disease, incidence/prevalence of dsDNA antibodies (anti-dsDNA) and hypocomplementaemia. The objective of this study is to describe the development of ATIL in patients with non-infectious uveitis in a single tertiary center. METHODS: Retrospective description of a case series. RESULTS: We describe three patients with noninfectious uveitis (NIU) of different etiologies who developed antinuclear antibody (ANA) and anti-dsDNA antibody positivity, arthritis and, in one case, skin lesions under adalimumab treatment. The condition resolved in all of them after adalimumab withdrawal. Corticosteroids were required in one patient, non-steroidal anti-inflammatory drugs in two patients, and hydroxychloroquine in one of them. None required another immunosuppressive drug. A subsequent control of the NIU could continue to be carried out without anti-TNF-α therapy in two patients and in the remaining a switch was made to another anti-TNF-α (golimumab). CONCLUSION: The current report describes three cases of ATIL in patients with different types of NIU which share some common features: ANA positivity, articular symptoms, and a temporal relationship between symptoms onset and anti-TNF-α treatment. A review of the literature and comparison with the few previous reported ATIL cases was conducted as well.

RESUMO

PURPOSE: To develop an objective intraocular inflammation composite score. METHODS: Cross-sectional study. Non-invasive image acquisition and processing were conducted from April 2017 to April 2019. Inflammation-grade stratified eyes from patients with active, inactive uveitis and healthy controls were recruited. After clinical assessment, four anterior and posterior segment image acquisition protocols per eye, using swept-source optical coherence tomography (SS-OCT), were performed at inclusion. Eight imaging biomarkers in three domains: anterior, intermediate and posterior were studied. They were ranked and selected by discriminatory power and correlation with clinical scores. A final SS-OCT-derived composite uveitis activity score (SS-UAS) was developed through multiple linear regression. RESULTS: We studied 224 eyes with uveitis (165 active and 59 inactive) from 165 patients (mean age 46.6 SD 15.5 years; 55.3% women) and 38 eyes from 19 healthy controls (mean age 43.6 SD 17.1; 47% women). The selected SS-OCT-derived biomarkers to build the final score were anterior chamber hyper-reflective dots (anterior), high-definition relative vitreous intensity (intermediate) and the averaged thickened retinal index (posterior). Swept-source (SS)-UAS was highly discriminant between active and inactive, and between active and healthy eyes (means 2.06 SD 1.86, 0.93 SD 0.44, and 0.96 SD 0.38, respectively, both p -, Mann-Whitney U). Construct validity (Cronbach's alpha = 0.7), internal consistency, criterion validity and reliability (concordance correlation coefficient intra-rater = 0.99, 95% CI: 0.98-0.99; inter-rater = 0.98, 95% CI: 0.96-0.99) were favourable. CONCLUSIONS: Global intraocular inflammation can potentially be staged and scored objectively, continuously, consistently and in a valid manner through the combined processing of SS-OCT scans.

RESUMO

BACKGROUND AND AIM: There is increasing interest regarding SARS-CoV-2 infection in patients with autoimmune and immune-mediated inflammatory diseases (AI/IMID) with some discrepancies in different cohorts about their risk and outcomes. The aim was to describe a multidisciplinary cohort of patients with AI/IMID and symptomatic SARS-CoV-2 infection in a single tertiary center and analyze sociodemographic, clinical, and therapeutic factors associated with poor outcomes. METHODS: A retrospective observational study was conducted from the 1st of March until May 29th, 2020 in a University tertiary hospital in Barcelona, Spain. Patients with an underlying AI/IMID and symptomatic SARS-CoV-2 infection were identified in our local SARS-CoV-2 infection database. Controls (2:1) were selected from the same database and matched by age and gender. The primary outcome was severe SARS-CoV-2 infection, which was a composite endpoint including admission to the intensive care unit (ICU), need for mechanical ventilation (MV), and/or death. Several covariates including age, sex, and comorbidities among others were combined into a multivariate model having severe SARS-CoV-2 as the dependent variable. Also, a sensitivity analysis was performed evaluating AID and IMID separately. RESULTS: The prevalence of symptomatic SARS-CoV-2 infection in a cohort of AI/IMID patients was 1.3%. Eighty-five patients with AI/IMID and symptomatic SARS-CoV-2 were identified, requiring hospitalization in 58 (68%) cases. A total of 175 patients admitted for SARS-CoV-2 (58 with AI/IMID and 117 matched-controls) were analyzed. In logistic regression analysis, a significant inverse association between AI/IMID group and severe SARS-CoV-2 (OR 0.28; 95% CI 0.12-0.61; p = 0.001), need of MV (OR 0.20; IC 95% 0.05-0.71; p = 0.014), and ICU admission (OR 0.25; IC 95% 0.10-0.62; p = 0.003) was found. CONCLUSIONS: Patients with AI/IMID who require admission for SARS-CoV-2 infection have a lower risk of developing severe disease, including the need to stay in the ICU and MV.

RESUMO

Purpose: To report a case of cystoid macular edema (CME) secondary to juvenile idiopathic arthritis (JIA)-associated uveitis.Case report: 26-year-old female patient presented with CME in both eyes. CME became refractory and TCZ-IV was initiated. After 12 infusions was stopped because grade 1 neuropenia developed. On examination,visual acuity of the right eye was 20/80. Spectral domain optical coherence tomography (SD-OCT) of the right eye revealed CME. Subcutaneous (TCZ-SC) was initiated. After six injections of TCZ-SC, ophthalmic examination revealed no signs of active inflammation, and central foveal thickness decreased.Conclusion: TCZ-SC seems to have a role in the treatment of CME secondary to juvenile idiopathic arthritis (JIA)-associated uveitis.

RESUMO

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.

RESUMO

PURPOSE: To identify predictive response optical coherence tomography (OCT) findings in uveitic macular edema (UME) treated with intravitreal dexamethasone implant (DEX). METHODS: Retrospective study of 66 eyes (53 patients) treated with DEX for UME. SD-OCT macular scans were collected prior to DEX treatment and 6 weeks and 3 months after the DEX implant. OCT images were evaluated for qualitative and quantitative characteristics (central retinal thickness, CRT and macular volume, MV). A multivariate analysis of covariance (ANCOVA) was carried out to study the predictive influence of OCT and clinical covariates on outcomes. The main outcome was a composite endpoint based on the simultaneous gain of 5 or more letters associated with a 20% or more reduction in CRT. RESULTS: A significant improvement in BCVA at 6 weeks (mean change from baseline -0.2, SD 0.3) and 3 months (mean -0.2, SD 0.4) was observed after the DEX implant. A significant decrease in CRT (change from baseline -187.7 µm at 3 months) and MV (change from baseline -1.7 mm3 at 3 months) were also observed. An association of ≥ 5-letter improvement in BCVA and a ≥ 20% CRT reduction was observed in 44.6% of cases at 6 weeks and 31.4% at 3 months. ANCOVA multivariate analyses found CRT at 3 months independent from baseline clinical variables but from CRT. CONCLUSION: DEX implant is an effective treatment for UME independently of basal characteristics, producing both a gain of visual acuity and improvement of macular anatomy by OCT measures at 3 months.

RESUMO

PURPOSE: To describe clinical findings through ultra-wide field (UWF) images and optical coherence tomography angiography (OCT-A), in Susac's syndrome (SS). METHODS: SS patients were retrospectively analyzed in a single center. Clinical features, ultra-wide-field retinographies (UWF-PR), UWF fluorescein angiographies (UWF-FA), and optical coherence tomography angiography & en face (OCT-A/EF) were reviewed. RESULTS: Twelve eyes from six patients with a mean follow-up of 35.66 months ± SD 36.88 were included. UWF-PR showed areas of retinal whitening and cotton-wool spots in all the eyes after acute attack. Segmentary mid peripheral arteriolitis could be observed in five eyes by UWF-FA in acute and convalescent stages. OCT-A revealed capillary density changes in all of the affected eyes. During the acute phase there was a well-preserved superficial capillary network, while deep retinal plexus showed a lower density in the affected areas. OCT-A/EF revealed deep retinal plexus drop-out and surrounding edematous retina in acute attacks, becoming atrophic over time. Conversely, superficial plexus was much less affected. Perifoveal reperfusion was seen in seven eyes after the acute attack. CONCLUSIONS: UWF-PR/FA and OCT-A/EF might be helpful to stablish an early diagnosis and to monitor SS progression.
