Clinical features, diagnosis, treatment, and course of ocular sarcoidosis with or without uveitis: A retrospective, comparative study.

OBJECTIVE: To evaluate and compare characteristics, diagnosis, treatment, visual prognosis, and course between ocular sarcoidosis with or without uveitis in a population in Southern France. METHODS: We retrospectively analyzed data from patients with ocular sarcoidosis in a tertiary eye care center in Nice from January 2003 to December 2021. The inclusion criterion was biopsy-proven ocular sarcoidosis according to IWOS criteria as the first clinical manifestation of sarcoidosis. RESULTS: A total of 25 patients were included. Twenty patients had uveitis (70% panuveitis, 20% intermediate uveitis, and 10% anterior uveitis) and five patients had non-uveitic ocular sarcoidosis (one patient with dacryoadenitis, one patient with orbital granuloma, two patients with palpebral granuloma, and one patient with episcleritis). Only the cases with uveitis had bilateral involvement (85% of cases). There was no significant difference in ethnicity, biopsy diagnosis, systemic manifestations, or treatment between the two groups. Final visual outcomes remained good for both groups, with 96% of patients with BCVA>20/50, with no significant difference. Patients with non-uveitic sarcoidosis experienced less recurrence on treatment (P=0.042) and more remission (P=0.038) than patients with uveitis. Eighty percent of patients with uveitis had at least three suggestive clinical intraocular signs meeting IWOS criteria. CONCLUSION: In this population in Southern France, uveitis was the most common presentation of ocular sarcoidosis. The type of ocular sarcoidosis does not appear to be correlated with the type of systemic manifestations, use of systemic therapy, or visual prognosis, but patients with non-uveitic ocular sarcoidosis appear to have a better course with fewer recurrences on treatment and more remission than patients with uveitic ocular sarcoidosis.

Atypical Cogan's syndrome: A case report.

Cogan's syndrome is a rare autoimmune inflammatory disease, characterized by interstitial keratitis and audio-vestibular signs. The syndrome was first described in 1945 by David G. Cogan. Then, it was only in 1980 when Haynes et al. proposed diagnostic criteria for patients with other symptoms and was qualified as atypical form of Cogan's syndrome. Herein, we report a case of a 28-year-old woman with atypical Cogan's syndrome. The patient was treated with corticosteroids and received a cochlear implant.

Idiopathic uveitis presents different characteristics and outcome from juvenile idiopathic arthritis- related uveitis / Uveíte idiopática apresenta características e desfecho diferentes da uveíte associada à Artrite Idiopática Juvenil

ABSTRACT Objective: To describe the clinical features and outcomes of patients with uveitis associated with juvenile idiopathic arthritis (JIA) and idiopathic uveitis. Methods: This was an observational, retrospective study, conducted in a tertiary center. Patients under 18 years old who experienced at least one episode of uveitis and followed between 2000 and 2019 were included. Results: A total of 82 patients were included, of whom 43 had idiopathic uveitis and 39 had uveitis associated with JIA. Anterior uveitis was the primary site of ocular inflammation (76.8%) and occurred in 24 and 39 patients with idiopathic uveitis and uveitis associated with JIA arthritis, respectively (p=0.02). The complete response to corticotherapy was more frequent in uveitis associated with JIA (p=0.001). Total and partial responses to biological disease modifying antirheumatic drugs were more frequent in uveitis associated with JIA (p=0.025) and idiopathic uveitis (p=0.045), respectively. There were 203 complications: cataracts were more frequently present in idiopathic uveitis (p=0.05), while synechiae was more frequent in uveitis associated with JIA (p=0.02). Conclusion: Idiopathic uveitis and uveitis associated JIA frequently follow a chronic course and an increased risk of visual loss in childhood. The uveitis associated with JIA showed better response to systemic corticotherapy and total response to biologic disease modifying antirheumatic drugs more frequently.

RESUMO Objetivos: Descrever as características clínicas e desfechos dos pacientes com uveíte associada à Artrite Idiopática Juvenil (AIJ) e da Uveíte Idiopática. Métodos: Este foi um estudo retrospectivo observacional conduzido em um centro terciário. Foram incluídos pacientes abaixo dos 18 anos de idade que apresentaram pelo menos um episódio de uveíte e que estiveram em acompanhamento médico entre os anos de 2000 e 2019. Resultados: Foram incluídos 82 pacientes, sendo 43 com uveíte idiopática e 39 com uveíte associada à AIJ. A uveíte anterior foi o sítio primário de acometimento (76,8%) em 24 e 39 pacientes com uveíte idiopática e uveíte associada à AIJ, respectivamente (p=0.02). Resposta total à corticoterapia foi mais frequente na uveíte associada à AIJ (p=0.001). Respostas total e parcial às drogas antirreumáticas modificadoras de doença biológicas foram mais frequentes na uveíte associada à AIJ (p=0.025) e na uveíte idiopática (p=0.045), respectivamente. Foram encontradas 203 complicações: a catarata foi mais frequente na uveíte idiopática (p=0.05), enquanto a sinéquia foi mais frequente na uveíte associada à AIJ (p=0.02). Conclusão: A uveíte idiopática e a uveíte associada à AIJ frequentemente apresentam um curso crônico e um risco elevado de perda visual na infância. A uveíte associada à AIJ apresentou melhor resposta à corticoterapia sistêmica e resposta total às drogas modificadoras de doença reumática biológicas mais frequentemente.

Simultaneous cytomegalovirus uveitis and HIV retinopathy / Uveíte por citomegalovírus e retinopatia por HIV simultâneas

ABSTRACT A 41 year-old man presented with unilateral vision loss for a week and constitutional symptoms for 3 months. Ophthalmic evaluation revealed cotton wool spots on the right eye and widespread retinal necrosis and hemorrhage on the left eye, suggestive of cytomegalovirus uveitis and HIV infection and retinopathy, and confirmed by serology. The patient was treated with ganciclovir and highly active antiretroviral therapy and preserved contralateral vision. Clinicians should be aware of uveitis and retinopathies to prevent irreversible vision loss and systemic conditions.

RESUMO Paciente do sexo masculino, 41 anos, com queixa de perda de acuidade visual unilateral por 1 semana e sintomas constitucionais por 3 meses. Ao exame oftalmológico, apresentava exsudatos algodonosos, em olho direito, e áreas de necrose e hemorragias retinianas, em olho esquerdo, com suspeita de uveíte por citomegalovírus e retinopatia por HIV, confirmadas por sorologias. O paciente foi tratado com ganciclovir e terapia antirretroviral e preservou a visão contralateral. Os oftalmologistas devem estar atentos para casos de uveítes e retinopatias, para prevenirem perda visual irreversível e condições sistêmicas.

Retinal thickness profiles in patients with Behçet uveitis during remission / Perfis de espessura da retina em pacientes com uveíte de Behçet durante remissão

ABSTRACT Purpose: The purpose of this study was to evaluate the intraretinal layer thickness in the macular region and its correlation with the duration of uveitis and visual acuity in patients with Behçet uveitis. Methods: In this cross-sectional study, we included 93 eyes of 57 patients with Behçet uveitis and 100 eyes of 50 healthy individuals admitted to a tertiary center from January to September 2017. We performed macular measurements in all subjects via spectral domain-optical coherence tomography (SD-OCT) and divided the retina into layers using automated segmentation software on the SD-OCT device. We then compared layer thicknesses between the patient and control groups and evaluated the correlation between OCT parameters and the duration of uveitis and visual acuity in the patient group. Results: Our records show a mean age of 37.9 ± 10.8 (18-64) years and 37.7 ± 12.2 (21-61) years in the patient and control groups (p=0.821), respectively. Meanwhile, data reveal a mean duration of uveitis of 6.9 ± 4.7 (1-20) years. We found a reduction in the total outer layer thickness in the patient group (p<0.001). However, we did not find a statistically significant difference in the inner retinal layers except in the inner nuclear layer. The duration of uveitis negatively correlated with the outer retinal layer's thickness (correlation coefficient = -0.250). On the other hand, visual acuity positively correlated with the central macular, the total inner layer, and the outer retinal layer thicknesses (correlation coefficients: 0.194, 0.154, and 0.364, respectively). However, the inner nuclear layer negatively correlated with visual acuity. Conclusions: Using retinal segmentation via SD-OCT for follow-ups can help estimate visual loss in patients with Behçet uveitis, which can cause significant changes in intraretinal layers in the macular region.

RESUMO Objetivo: Avaliar a espessura das camadas intraretinianas na região macular e sua relação com a duração da uveíte e acuidade visual em pacientes com uveíte de Behçet. Métodos: Este estudo transversal incluiu 93 olhos de 57 pacientes com uveíte de Behçet e 100 olhos de 50 indivíduos saudáveis que foram admitidos em um hospital terciário entre janeiro de 2017 e setembro de 2017. As medições maculares foram realizadas com tomografia de coerência óptica de domínio espectral (SD-OCT) em todos os pacientes. A retina foi dividida em camadas usando software de segmentação automatizado no dispositivo SD-OCT. As espessuras da camada foram comparadas entre os pacientes e os grupos controle. No grupo de pacientes, foi avaliada a correlação entre os parâmetros obtidos na OCT e a duração da uveíte e acuidade visual. Resultados: A média de idade foi de 37,9 ± 10,8 (18-64) no grupo de pacientes e 37,7 ± 12,2 (21-61) no grupo controle (p=0,821). A duração média da uveíte foi de 6,9 ± 4,7 (1-20) anos. A espessura total das camadas externas no grupo de pacientes foi reduzida (p<0,001). Uma diferença estatisticamente significativa não foi encontrada nas camadas internas da retina, exceto na camada nuclear interna. Uma correlação negativa foi detectada entre a duração da uveíte e a espessura da camada externa da retina (coeficiente de correlação = -0,250). Uma correlação positiva significativa foi detectada entre a acuidade visual e a espessura macular central bem como a espessura total das camadas internas e externas da retina (coeficientes de correlação 0,194; 0,154 e 0,364, respectivamente). A camada nuclear interna foi negativamente correlacionada com a acuidade visual. Conclusões: A uveíte de Behçet pode causar alterações significativas nas camadas intraretinianas na região macular. A segmentação da retina com SD-OCT pode ser útil para acompanhamentos e para estimar a perda visual em pacientes com uveíte de Behçet.

Ophthalmological findings in brucellosis.

PURPOSE: To evaluate the ophthalmological findings in patients diagnosed with acute, subacute or chronic brucellosis and to determine the effects of this disease on ocular structures. METHODS: Eighty-seven patients diagnosed with brucellosis and 71 healthy cases (as a control group) were enrolled in this prospective study. All participants underwent a complete ophthalmic evaluation, including slit lamp biomicroscopic examination, Goldman applanation tonometry, specular microscopy, optical coherence tomography and fundoscopy with pupil dilation. RESULTS: Overall, ocular involvement was present in 47 eyes of 27 (31.03%) patients diagnosed with brucellosis and was most common in the chronic brucellosis group. In the acute brucellosis group, papillary conjunctivitis in 8 eyes of 4 patients and anterior uveitis in 10 eyes of 6 patients were noted. In the subacute brucellosis group, papillary conjunctivitis in 4 eyes of 2 patients and sequelae of anterior uveitis in 6 eyes of 3 patients were observed. In the chronic brucellosis group, panuveitis in 4 eyes of 2 patients, choroiditis in 4 eyes of 2 patients, and signs of previous anterior uveitis in 11 eyes of 6 patients were noted. Visual acuity was significantly worse in patients with acute anterior uveitis (AAU) or previous anterior uveitis (PAU) compared with the control cases. CONCLUSION: Ocular involvement should be kept in mind in patients with brucellosis, especially acute, and brucellosis should be included in the differential diagnosis of patients with anterior uveitis living in endemic areas, since the clinical presentation of the disease may not be overt.

Behçet's disease uveitis.

Uveitis in Behçet's disease (BD) is frequent (40% of cases) and is a major cause of morbidity. The age of onset of uveitis is between 20 and 30 years. Ocular involvement includes anterior, posterior or panuveitis. It is non-granulomatous. Uveitis may be the first sign of the disease in 20% of cases or it may appear 2 or 3 years after the first symptoms. Panuveitis is the most common presentation and is more commonly found in men. Bilateralisation usually occurs on average 2 years after the first symptoms. The estimated risk of blindness at 5 years is 10-15%. BD uveitis has several ophthalmological features that distinguish it from other uveitis. The main goals in the management of patients are the rapid resolution of intraocular inflammation, prevention of recurrent attacks, achievement of complete remission, and preservation of vision. Biologic therapies have changed the management of intraocular inflammation. The aim of this review is to provide an update previous article by our team on pathogenesis, diagnostic approaches, identification of factors associated with relapse and the therapeutic strategy of BD uveitis.

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.

French recommendations for the management of non-infectious chronic uveitis.

This French National Diagnostic and Care Protocol (NDPC) includes both pediatric and adult patients with non-infectious chronic uveitis (NICU) or non-infectious recurrent uveitis (NIRU). NICU is defined as uveitis that persists for at least 3 months or with frequent relapses occurring less than 3 months after cessation of treatment. NIRU is repeated episodes of uveitis separated by periods of inactivity of at least 3 months in the absence of treatment. Some of these NICU and NIRU are isolated. Others are associated with diseases that may affect various organs, such as uveitis associated with certain types of juvenile idiopathic arthritis, adult spondyloarthropathies or systemic diseases in children and adults such as Behçet's disease, granulomatoses or multiple sclerosis. The differential diagnoses of pseudo-uveitis, sometimes related to neoplasia, and uveitis of infectious origin are discussed, as well as the different forms of uveitis according to their main anatomical location (anterior, intermediate, posterior or panuveitis). We also describe the symptoms, known physiopathological mechanisms, useful complementary ophthalmological and extra-ophthalmological examinations, therapeutic management, monitoring and useful information on the risks associated with the disease or treatment. Finally, this protocol presents more general information on the care pathway, the professionals involved, patient associations, adaptations in the school or professional environment and other measures that may be implemented to manage the repercussions of these chronic diseases. Because local or systemic corticosteroids are usually necessary, these treatments and the risks associated with their prolonged use are the subject of particular attention and specific recommendations. The same information is provided for systemic immunomodulatory treatments, immunosuppressive drugs, sometimes including anti-TNFα antibodies or other biotherapies. Certain particularly important recommendations for patient management are highlighted in summary tables.

Fecal calprotectin levels in acute anterior uveitis in patients with spondyloarthritis / Níveis de calprotectina fecal na uveite anterior aguda em pacientes com espondiloartrites

ABSTRACT Purpose: This study measured fecal calprotectin levels in a series of patients with anterior uveitis in order to determine whether anterior uveitis patients with associated spondyloarthritis have higher levels of fecal calprotectin than patients with anterior uveitis of other etiologies. A third group of patients with spondyloarthritis without uveitis was also evaluated to understand the role of acute anterior uveitis in increasing fecal calprotectin. Methods: In this cross-sectional study, 28 patients were divided into three groups: (a) Group 1, spondyloarthritis and uveitis (n=9); (b) Group 2, spondyloarthritis without uveitis (n=10); and (c) Group 3, uveitis without spondyloarthritis (n=9). The levels of fecal calprotectin were determined. Results: Groups 1 and 2 showed higher median fecal calprotectin levels (101.0 and 93.0 µg/g, respectively) compared with Group 3 (9.0 µg/g) (p=0.02). However, no relationship between fecal calprotectin levels and the presence of uveitis with spondyloarthritis could be demonstrated. Conclusion: Patients with spondyloarthritis with or without acute anterior uveitis have significantly elevated levels of fecal calprotectin. This test may be useful for differentiating spondyloarthrit-associated uveitis from uveitis of other etiologies.

RESUMO Objetivo: Este estudo avaliou os níveis de calprotectina fecal em uma série de pacientes com uveíte anterior na tentativa de determinar se pacientes com uveíte associada com espondiloartrites apresentam níveis mais elevados desta proteína do que pacientes com uveíte anterior de outras etiologias. Um terceiro grupo com espondiloartrites sem uveíte também foi incluído na avaliação para entendimento do papel da uveíte anterior no aumento da calprotectina fecal. Métodos: Estudo transversal de 28 pacientes divididos em três grupos: (a) com espondiloartrites e uveíte (n=9); (b) com espondiloartrites sem uveíte (n=10) e (c) com uveíte sem espondiloartrites (n=9). A dosagem de calprotectina fecal foi avaliada. Resultados: Pacientes com uveíte anterior associada a espondiloartrites apresentaram valores medianos maiores de calprotectina fecal (101 µg/g) que os valores dos pacientes com uveíte sem espondiloartrites (9 µg/g), pacientes com espondiloartrites sem uveíte que também demonstraram valores maiores (93.0 µg/g) que os dos pacientes com uveíte sem espondiloartrites (p=0,02). Conclusão: Pacientes com espondiloartrites com e sem uveíte anterior aguda demonstraram níveis significativamente elevados de calprotectina fecal. Este teste pode ser útil na diferenciação entre uveítes associadas com espondiloartrites de uveítes de outras etiologias. Entretanto, não foi possível demonstrar associação entre o aumento dos níveis de calprotectina fecal e a presença da uveíte em espondiloartrites.

Uveitis in children: Epidemiological, clinical and prognostic characteristics.

PURPOSE: The purpose of this study is to describe the characteristics and prognostic factors of pediatric uveitis in a French university referral hospital. METHODS: We performed a retrospective study of all cases of all pediatric uveitis seen at our institution over a 7-year period. RESULTS: A total of 141 eyes of 86 children were included. The mean age was 10.7 years, and 61.6% were girls. The uveitis was bilateral in 64.0% of cases. Anterior uveitis (41.0%) and intermediate uveitis (32.0%) were the most frequent forms. The most frequent etiologies were idiopathic (27.9%), juvenile idiopathic arthritis (25.6%) and pars planitis (18.6%). During the follow-up period, systemic corticosteroids were received by 43.0% of children, immunosuppressive drugs by 31.4% and biological agents by 18.6%. At the final examination, complications were present in 67.0% of patients: 18.0% had cataracts, and 11.3% had intraocular hypertension. Posterior synechiae were present in 27.6% of eyes, optic disc edema in 10.5% and macular edema in 16.2%. At the last visit, visual acuity was better than 20/200 in 97.0% of cases. The presence of band keratopathy, cataract or glaucoma was an independent predictor of impaired visual outcomes at follow-up. CONCLUSION: Juvenile idiopathic arthritis is one of the most frequent and severe pediatric uveitides. Close monitoring and early treatment could prevent complications.

[Sarcoid uveitis: Ophthalmologist's and internist's viewpoints]. / Uvéites sarcoïdosiques : regards croisés de l'ophtalmologiste et de l'interniste.

Sarcoidosis is one of the leading causes of inflammatory eye disease. All ocular structures can be affected, but uveitis is the main manifestation responsible for vision loss in ocular sarcoidosis. Typical sarcoid anterior uveitis presents with mutton-fat keratic precipitates, iris nodules, and posterior synechiae. Posterior involvement includes vitritis, vasculitis, and choroidal lesions. Cystoid macular edema is the most important and sight-threatening consequence of sarcoid uveitis. Patients with clinically isolated uveitis at diagnosis rarely develop other organ involvement. Even though, ocular sarcoidosis can have a severe impact on visual prognosis, early diagnosis and a wider range of available therapies (including intravitreal implants) have lessened the functional impact of the disease, particularly in the last decade. Corticosteroids are the cornerstone of treatment for sarcoidosis, but up to 30% of patients achieve remission with requiring high-dose systemic steroids. In these cases, the use of steroid-sparing immunosuppressive therapy (such as methotrexate) is unavoidable. Among these immunosuppressive treatments, anti TNF-α drugs have been a revolution in the management of non-infectious uveitis.

Coriorretinopatia de Birdshot: relato de caso e perspectivas sobre o tratamento / Birdshot chorioretinopathy: a case report and perspectives on its treatment

RESUMO A coriorretinopatia de Birdshot é uma uveíte posterior bilateral crônica rara que acomete, preferencialmente, mulheres de meia-idade. O quadro clínico é composto de pouco ou nenhum processo inflamatório de segmento anterior, associado a vitreíte e lesões coriorretinianas ovoides branco-amareladas de característica hiperfluorescente na angiofluoresceinografia e hipofluorescente na angiografia com indocianina verde. O tratamento se dá por meio de corticoides e outras drogas imunossupressoras. Todavia, em alguns casos, a doença é refratária a tal terapêutica, sendo necessário lançar mão de outras drogas, como os agentes biológicos. O presente artigo busca relatar um caso de coriorretinopatia de Birdshot em ajuste de terapia imunossupressora que evoluiu com má resposta às drogas iniciais e bom controle após uso de imunobiológico e discutir as opções terapêuticas disponíveis atualmente.

ABSTRACT Birdshot chorioretinopathy is a rare chronic bilateral posterior uveitis that preferentially affects middle-aged women. The clinical picture is composed of little or no anterior segment inflammatory process, associated with vitritis and yellowish-white ovoid chorioretinal lesions with hyperfluorescent characteristics on fluorescein angiography and hypofluorescent characteristics on green indocyanine green angiography. Treatment is with corticosteroids and other immunosuppressive drugs. However, in some cases, the disease is refractory to such therapy, making it necessary to resort to other drugs such as biological agents. The present article seeks to report a case of Birdshot chorioretinopathy in an adjustment of immunosuppressive therapy that evolved with poor response to the initial drugs and good control after the use of immunobiologicals and discuss the currently available therapeutic options.

Aspects épidémiologique et clinique des uvéites au Niger: analyse rétrospective d'une série de 127 cas colligés sur 5 ans / Epidemiological and clinical aspects of uveitis in Niger: A retrospective analysis of a series of 127 cases collected during 5 years

Contexte & objectif L'uvéite est peu très peu documentée en Niamey. L'objectif de la présente étude était de décrire les aspects épidémiologique et clinique des uvéites. Méthodes. Il s'agissait d'une étude rétrospective et descriptive portant sur 127 dossiers des patients suivis pour uvéites à la clinique lumière de Niamey sur une période de 5 ans (2015 ­ 2020). Les paramètres sociodémographiques, cliniques et thérapeutiques ont été recueillis. Résultats. La fréquence hospitalière des uvéites était de 0,21 %. Le sex-ratio était de 1,01. L'âge moyen des patients était de 40,76 ans. La douleur oculaire représentait le motif de consultation le plus fréquent avec 51 ,97 %. La majorité des patients avait présenté 2 épisodes d'uvéites soit 57,48 %. L'atteinte était unilatérale dans 70,97 % et les uvéites antérieures étaient les plus fréquentes 66,93 %. Les étiologies étaient identifiées chez seulement 7,87 % des patients dont près de la moitié était la tuberculose. 33,07 % des patients avaient présenté des complications. Conclusion. Il ressort de cette étude que l'uvéite touche plus des jeunes adultes, ses étiologies sont indéterminées dans la majorité de cas. Les formes antérieures sont plus fréquentes.

Context and objective Little is known about Uveitis in Niamey. This study aimed to analyze the epidemiological and clinical aspects of uveitis. Methods. This was a retrospective, descriptive study of 127 records of patients followed up for uveitis at the Niamey Lumière Clinic over a 5-year period (2015 ­ 2020). Sociodemographic, clinical and therapeutic parameters were collected. Results. The hospital frequency of uveitis was 0.21%. The sex ratio was 1.01. The mean age of patients was 40.76 years. Ocular pain was the most frequent reason for consultation, accounting for 51.97 %. The majority of patients (57.48%) had presented with 2 episodes of uveitis. Involvement was unilateral in 70.97 %, and anterior uveitis was the most frequent, at 66.93 %. Etiologies were identified in only 7.87 % of patients, of which tuberculosis accounted for almost half. Complications occurred in 33.07 % of patients. Conclusion. This study shows that uveitis affects mainly young adults, and its etiologies are undetermined in most cases. Anterior forms are more frequent.

Congenital ocular toxoplasmosis in consecutive siblings / Toxoplasmose ocular congênita em irmãos consecutivos

ABSTRACT Toxoplasma gondii infection can cause ocular manifestations after acquired and congenital disease. We report two cases of symptomatic congenital toxoplasmosis with ocular involvement in non-twin siblings, with a 2-year interval between pregnancies. Vertical transmission of toxoplasmosis in successive pregnancies, which was once considered impossible, is now found to be plausible even in immunocompetent subjects.

RESUMO A infecção pelo Toxoplasma gondii pode causar manifestações oculares tanto após a sua forma congênita quanto a sua forma adquirida. Reportamos aqui dois casos de toxoplasmose congênita sintomática com envolvimento ocular em irmãos não gêmeos, com intervalo de 2 anos entre gestações. A transmissão vertical da toxoplasmose em gestações sucessivas, outrora considerada impossível, é um evento plausível mesmo em indivíduos imunocompetentes.

Serum Maresin 1 levels in idiopathic acute anterior uveitis patients.

PURPOSE: The purpose of the present study is to assess the levels of Maresin 1 (MaR1) in patients with idiopathic acute anterior uveitis (IAAU) and to compare the MaR1 results with healthy controls. METHODS: This study includes 24 patients with idiopathic AAU and 24 healty controls (C). The serum MaR1 levels were analyzed using enzyme-linked immunosorbent assays (ELISA). The erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels were measured at the time of diagnosis. RESULTS: MaR1 levels were statistically significant when the IAAU group was compared with group C (P<0.001). When idiopathic AAU patients were compared with group C, no statistically significant difference was found between ESR and CRP levels (P=0.086, P=0.549 respectively). CONCLUSION: Serum MaR1 levels are an important biomarker of disease in patients with idiopathic AAU.

Infliximab therapy in Behçet's uveitis.

PURPOSE: To evaluate the efficacy of infliximab (IFX) therapy in patients with Behçet's uveitis (BU) refractory to conventional immunomodulatory treatment (IMT). MATERIALS AND METHODS: This study, trial registration number TCTR20200806007, included cases of BU with a minimum of 18 months follow-up on IFX treatment. Demographic characteristics, ophthalmological examination findings, control of ocular inflammation with IFX, response to treatment and the rate of clinical remission were analyzed in this study. RESULTS: Sixty-two eyes of 35 patients on IFX therapy were included in the study. The mean follow-up was 49.5±25.9months. The mean frequency of recurrences during the IMT was 1.47±0.78 (attacks/year), decreasing to 0.31±0.40 (attacks/year) with IFX (P<0.001). Visual acuity improved significantly in the 1st month of IFX treatment (P=0.026). Partial response to treatment was achieved in 91.4% of cases. CONCLUSION: IFX is a safe and effective treatment in cases of BU refractory to conventional IMT.

[Colchicine and non-severe ocular inflammation excluding Behcet's disease: 16 cases and literature review]. / Colchicine et inflammation oculaire non sévère hors maladie de Behcet : 16 cas et revue de la littérature.

INTRODUCTION: Colchicine is a narrow therapeutic margin drug that does not have the adverse effects of corticosteroids and immunosuppressants. Its use in non-severe ocular inflammatory disease excluding Behcet's disease has not been studied. METHODS: We included patients seen in the internal medicine department of Dijon University Hospital consecutively between September 2020 and September 2021 if they had received colchicine during their pathology. Patients with suspected Behçet's disease were excluded. Treatment efficacy was studied in patients with at least one year of disease progression who had received more than one year of colchicine. Successful treatment was defined as a 50 % reduction in the number of annual relapses on colchicine. RESULTS: Sixteen patients were included (9 women and 7 men). They had recurrent anterior uveitis (n=10), recurrent scleritis (n=5) and intermediate uveitis. Opthalmological involvement was neither severe nor complicated. All patients combined, the annual relapse ratio (ARR) decreased from 1.8 (0.8-3.5) to 0.3 (0-1.6), (P=0.06). Colchicine was considered effective in three of 10 analyzable patients. In only one patient, treatment was stopped for adverse effects after six weeks. CONCLUSION: In view of the interesting benefit-risk ratio of colchicine, it seems appropriate to focus on this molecule in non-granulomatous anterior uveitis and non-severe recurrent scleritis.

[XEN 45® gel stent implantation in glaucoma surgery: Dual-center comparative study between steroid-induced glaucoma and primary open angle glaucoma]. / Implantation du dispositif XEN 45® dans la chirurgie du glaucome : étude bicentrique bispective s'intéressant au glaucome cortisonique par rapport au glaucome primitif à angle ouvert.

INTRODUCTION: XEN 45® gel stent is an ab interno aqueous humor drainage device indicated for moderate glaucoma refractory to medical management. Its efficacy has been demonstrated in primary open-angle glaucoma (POAG). However, there are few studies on secondary glaucoma, including steroid-induced glaucoma (CG), defined as optic neuropathy induced by using local or systemic corticosteroids without increased flare. METHODS: We conducted a dual-center comparative cohort study between April 2019 and January 2021. 66 operated eyes were included, divided into two groups: POAG (56 eyes) and GC (10 eyes). The primary endpoint was the relative reduction in intraocular pressure (IOP) at three months postoperatively in the GC group. Three outcomes were defined: total success, partial success and failure. RESULTS: The total success rate was 100% in the GC group and 42.6% in the POAG group. Preoperative IOP was 36.1±9.1mmHg and 19.0±7.3mmHg respectively. IOP reduction was 69.1±11.7% in the GC group and 21.8±30.3% in the POAG group. Patients were younger in the GC group (49.3±21.2 versus 71.1±8.4 years), and preoperative conjunctival preparation was longer in this group (12 versus 5 weeks). The needling rate was 17.9% in the POAG group and 10% in the GC group. CONCLUSION: The XEN 45® gel stent is effective in the treatment of steroid-induced glaucoma. Further studies will be required to identify predictive factors for success and to establish criteria for good candidacy.
