RESUMO

ABSTRACT Unvaccinated identical twins developed bilateral anterior uveitis soon after the onset of coronavirus disease 2019 symptoms. During follow-up, both patients developed choroiditis, and one twine developed posterior scleritis and serous retinal detachment. Prompt treatment with oral prednisone ameliorated the lesions, and no recurrence was observed at the 18-month follow-up. Choroiditis may rarely be associated with severe acute respiratory syndrome coronavirus 2 infection, and it responds well to corticosteroid therapy. Although the exact mechanism is unknown, we hypothesize that the virus may act as an immunological trigger for choroiditis.

RESUMO

INTRODUCCIÓN: El tratamiento de la tuberculosis (TB) ocular es un tema que genera controversia en el mundo. Para el correcto manejo de estos pacientes, es necesario el desarrollo de guías que consideren la epidemiología de la TB ocular en cada nación. El objetivo de este consenso fue discutir de forma interdisciplinaria la epidemiología, fisiopatología, clínica, diagnóstico, estudio y tratamiento de los pacientes con TB ocular, para establecer un algoritmo de tratamiento y proponer qué pacientes deben ser tratados en Chile y con qué tratamiento. Además, se establecieron acuerdos para efectuar quimioprofilaxis de los pacientes con TB latente que tienen indicación de tratamiento inmunosupresor por enfermedades inflamatorias oculares.

The treatment of ocular tuberculosis (TB) remains controversial worldwide. The development of guidelines for ocular TB can facilitate the approach and management of these patients. These guidelines should be developed regionally, considering the local TB epidemiology. The objectives of this consensus are: to initiate an interdisciplinary discussion about the epidemiology, pathophysiology, clinical presentation, diagnosis, workup and treatment of patients with ocular TB, to establish a treatment algorithm and define which patients should be treated in Chile and how and, to analyze and discuss the published data regarding chemoprophylaxis for patients with latent TB who need to start immunosuppressive treatment due to inflammatory ocular conditions.

RESUMO

INTRODUCTION: Ampiginous Choroiditis is a rare posterior uveitis that combines clinical features of Acute Multifocal Posterior Placoid Pigment Epitheliopathy and Serpiginous Chorioretinitis. Its pathophysiology is poorly understood and further studies are necessary to understand which mechanisms start the immunologic reaction. CASE REPORT: The purpose of this article is to report a well-documented case of Ampiginous Choroiditis following in seven days a RT-PCR confirmed SARS-CoV-2 infection, suggesting that the infection might have contributed as a trigger. CONCLUSION: Timely diagnosis and correct treatment are paramount to improve the visual outcomes, and the patient had successful response to systemic steroids.

RESUMO

Vogt-Koyanagi-Harada (VKH) syndrome is an autoimmune, multisystemic disease characterized by severe bilateral granulomatous posterior, which can occur due to viral infection or vaccination. We report four cases that had a likely association between VKH disease and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. Two patients had VKH symptoms within 1 and 2 weeks after receiving the ChAdOx1 nCoV-19 vaccine. One patient presented with VKH symptoms 5 days after receiving the BNT162b2 vaccine, and one patient had symptoms within 4 weeks after receiving the CoronaVac vaccine. Early diagnosis and treatment of VKH disease are essential for the visual prognosis of this aggressive disease. Further in-depth studies are necessary to investigate this likely association to enable ophthalmologists to identify new assumed correlations between the diseases described in this study.

RESUMO

Las membranas neovasculares coroidea representan el crecimiento de nuevos vasos sanguíneos originados de la coriocapilar hacia el epitelio pigmentario de la retina o el espacio subretinal por una disrupción de la membrana de Bruch ocasionado por la inflamación prolongada. El desarrollo de las membranas neovasculares coroidea está estrechamente conectado a la morbilidad asociada con la coroidopatía punteada interna y puede ser su primera forma de presentación. La coroidopatía punteada interna es clasificada como una de las enfermedades de los síndromes de puntos blancos evanescentes, es una enfermedad infrecuente, bilateral y de origen desconocido. Se presenta un caso clínico de un paciente al cual se le diagnostica membranas neovasculares coroidea en el curso de una coroidopatía punteada interna con una presentación atípica o previa a las lesiones de coroiditis. La coroidopatía punteada interna complicada con membranas neovasculares coroidea compromete la visión central de forma considerable en pacientes jóvenes(AU)

Choroidal neovascular membranes represent the growth of new blood vessels originating from the choriocapillaris into the retinal pigment epithelium or subretinal space due to disruption of Bruch's membrane caused by prolonged inflammation. The development of choroidal neovascular membranes is closely connected to the morbidity associated with punctate inner choroidopathy and may be its first form of manifestation. Punctate Inner choroidopathy is classified as one of the evanescent white dot syndromes diseases, is a rare, bilateral disease of unknown origin. We present a case report of a patient diagnosed with choroidal neovascular membranes while suffering from punctate inner choroidopathy with an atypical manifestation or prior to choroiditis lesions. Punctate Inner choroidopathy when complicated with choroidal neovascular membranes compromises significantly the central vision in young patients(AU)

RESUMO

Purpose: To describe the presence of bacillary layer detachment (BALAD) in serpiginous-like choroiditis (SLC) in presumed intraocular tuberculosis. Observations: Clinical and multimodal imaging including fundus photography, fundus autofluorescence, and spectral domain and enhanced-deep imaging optical coherence tomography (OCT) of two cases of SLC in presumed intraocular tuberculosis. Two patients (26 and 38-year-old woman) presented with unilateral, decreased vision of acute onset. They were diagnosed with SLC in presumed intraocular tuberculosis, and OCT revealed splitting of the ellipsoid zone, resembling BALAD. All two patients showed complete resolution after treatment with antitubercular therapy (ATT). Conclusions and Importance: BALAD appears in the acute stage of SLC in presumed intraocular tuberculosis and resolves rapidly at the beginning of ATT.

RESUMO

Streptococcus suis is a Gram-positive pathogen that inhabits the upper respiratory tract and can cause severe systemic inflammatory disease in pigs, mainly during the nursery phase. Streptococcus suis is a reemergent pathogen, and outbreaks of its inducing disease represent significant economic losses for the pig industry worldwide. In this study, we described the clinical, pathological, and molecular aspects of an outbreak of S. suis infection with atypically high mortality. The outbreak occurred in nursery farms integrated into a cooperative in the state of Paraná, Brazil. Of the 30 nurseries, 10 were severely affected by the pathogen and had high economic losses. Clinical signs usually started approximately 10 days after weaning and were mainly characterized by acute nervous and locomotor disorders. The mortality of the affected batches usually ranged between 8% and 10%, but in some cases, it reached 18%. Nine piglets were submitted to post mortem examination. Macroscopically, the synovial joints were enlarged and contained fibrinous exudates. In the central nervous system, there was hyperemia of the leptomeningeal vessels associated with deposition of fibrin and purulent exudate in the leptomeninges. In three piglets, there was thickening of the choroid plexus associated with dilation of the lateral ventricles. Microscopic lesions were characterized mainly by fibrinosuppurative inflammation, which involved the synovial membranes, leptomeninges of the brain, and spinal cord. Furthermore, it also affects the choroid plexus, ependyma, nerve roots, and central canal of the spinal cord. S. suis was isolated from the cerebrospinal fluid, meningeal swabs, and/or synovial fluid of 8/9 piglets, and typified as serotype 9 by multiplex PCR.

Streptococcus suis é um patógeno Gram positivo que habita o trato respiratório superior e pode causar doença inflamatória sistêmica grave em suínos, principalmente durante a fase de creche. Streptococcus suis é um patógeno reemergente e surtos representam perdas econômicas significativas a suinocultura mundial. Neste estudo descrevemos os aspectos clínicos, patológicos e moleculares de um surto de infecção por S. suis com mortalidade atipicamente alta. O surto ocorreu em creches integradas a uma cooperativa do estado do Paraná, Brasil. Das 30 creches, 10 foram severamente afetadas pelo patógeno e apresentavam elevadas perdas econômicas. Os sinais clínicos iniciavam em torno de 10 dias após o desmame e eram caracterizados principalmente por sinais clínicos nervosos e locomotores agudos. A mortalidade dos lotes afetados variava entre 8% e 10%, mas em alguns casos ultrapassava 18%. Nove leitões foram submetidos ao exame post mortem. Macroscopicamente, as articulações sinoviais estavam aumentadas e continham exsudato fibrinoso. No sistema nervoso central havia hiperemia dos vasos leptomeníngeos associada a deposição de fibrina e exsudato purulento nas leptomeninges. Em três leitões havia espessamento do plexo coroide associado a dilatação dos ventrículos laterais. As lesões microscópicas eram caracterizadas principalmente por inflamação fibrinossupurativa que envolvia as membranas sinoviais, as leptomeninges do cérebro e medula espinhal. Além disso, também afetava o plexo coroide, epêndima, raízes nervosas e canal central da medula espinhal. S. suis foi isolado do líquido cefalorraquidiano, suabe de meninge e/ou líquido sinovial de 8/9 leitões e tipificado como sorotipo 9 por PCR multiplex.

RESUMO

ABSTRACT We report a case of a young Caucasian female presenting with sudden decrease of vision in the left eye, metamorphopsia, and nasal scotoma. Past medical history revealed a diagnosis of myasthenia gravis, which was currently treated with azathioprine, pyridostigmine, and prednisone. Ophthalmological examination showed fundus with clear vitreous and yellow-white lesions that were isolated and perimacular in the right eye, multiple and confluent in the macula, and punctate in periphery in the left eye. Laboratory workup ruled out the presence of infectious and inflammatory diseases. Fundus autofluorescence disclosed hypoautoflurescence with hyperfluorescent margins corresponding to the lesions observed in both eyes and the angiogram revealed hyperfluorescence since early phases without late leakage. Spectral-domain optical coherence tomography showed areas of intermittent retinal pigment epithelium elevations and disruption of the ellipsoid zone. She was diagnosed with punctate inner choroidopathy and then treated with an increased dose of daily prednisone, which resulted in progressive improvement of her visual acuity and anatomical status.(AU)

RESUMO Relato de caso de mulher jovem, caucasiana, com súbita diminuição de acuidade visual de olho esquerdo, metamorfopsia e escotoma nasal. Apresentava diagnóstico de Miastenia gravis, em tratamento com Azatioprina, Piridostigmina e Prednisona. Fundo de olho demonstrava vítreo límpido e lesões amarelo-esbranquiçadas, perimaculares e isoladas em olho direito, múltiplas e confluentes em mácula e pontilhadas em periferia no olho esquerdo. Exames laboratoriais descartaram doenças infecciosas e inflamatórias. Auto-fluorescência revelou lesões hipoautofluorescentes com margens hiperfluorescentes correspondentes às observadas em ambos os olhos, enquanto angiofluoresceinografia mostrou hiperfluorescência desde as fases iniciais sem vazamento tardio. Tomografia de coerência óptica de domínio espectral revelou áreas de elevações intermitentes do epitélio pigmentar da retina e interrupção da zona elipsóide correspondente. Definiu-se como diagnóstico a coroidopatia interna ponteada, sendo instituído aumento na dose diária de Prednisona, com melhoria progressiva da acuidade visual e do aspecto de fundo de olho da paciente.(AU)

RESUMO

PURPOSE: To present a case of an atypical unilateral multifocal choroiditis that occurred in temporal association to an acute covid-19 infection. METHOD: A 23-year-old highly myopic man presented with reduced vision in the right eye while under medical quarantine due to direct exposure to COVID-19 infection. Five days after developing mild COVID symptoms (fever, cough and anosmia) he noticed acute painless loss of central vision in his right eye. Systemic evaluation at presentation was positive for SARS-CoV-2 detected via both a pharyngeal swab and serologic titers. Dilated fundus exam was performed, followed by color fundus pictures, optic coherence tomography (OCT), fundus autofluorescence (FAF) and fluorescein angiography (FA). RESULTS: Fundoscopic examination of the right eye revealed the presence of multiple discrete, slightly elevated yellow-whitish placoid lesions at the posterior pole. The visual acuity was 20/800. The left eye was normal with 20/20 vision. The patient was placed on oral corticosteroids and the lesions rapidly improved. CONCLUSION: The patient had an MFC chorioretinitis around the same time that he had a documented acute covid infection. Though the temporal relationship could be by chance alone, communicating this case to the ophthalmic community is warranted to see if other similar cases are noted.

RESUMO

BACKGROUND: Classic serpiginous choroiditis (SC) usually begins in the peripapillary area and spreads centrifugally, however, in some patients, the lesion can arise in the macular region. An association between lesions resembling classic SC and tuberculosis was recognized as a possibly distinct clinical entity and named as tuberculous serpiginous-like choroiditis. The differentiation of this tuberculous entity from SC is critical because the treatment of the former with immunosuppressive drugs leads to several potential adverse effects, and such treatment can have devastating consequences because of the worsening of a concomitant tuberculous infection. CASE PRESENTANTION: A 31-year-old woman presented with unilateral decreased vision and a fundus examination consistent with macular serpiginous choroiditis. A non-reactor tuberculin skin test and normal thoracic CT scan ruled out tuberculosis. However, after 2 months of treatment with steroids and immunosuppressive drugs, the contralateral eye developed similar lesions, further raising the suspicions of ocular tuberculosis. We conducted QuantiFERON® TB Gold, which was positive; hence, antituberculous therapy was started on the patient. The lesions started healing within a few weeks. After 1 year of finishing the therapy, the lesions remained healed without any recurrence. CONCLUSIONS: Macular serpiginous-like choroiditis may be the initial presentation of presumed ocular tuberculosis. Nevertheless, the correct diagnosis of this entity can be challenging and delayed by the imprecise results from the currently available methods.

RESUMO

Purpose: To report the manifestation of Vogt-Koyanagi-Harada-like disease (VKH) following yellow fever vaccination.Methods: Case report.Results: A 34-year-old immunocompetent male had tinnitus, headache, and decreased vision after a booster dose of yellow fever vaccine. Visual acuity was 20/100 in the right eye and 20/80 in the left, with serous retinal detachment (SRD) and choroidal thickening identified on clinical examination and multimodal imaging. Lumbar puncture revealed pleocytosis and an increased protein content, but extensive investigations ruled out infectious/neurological diseases. Pulse intravenous methylprednisolone was given, followed by a tapering regimen of high-dose oral prednisone. Azathioprine was started early, 3 weeks after initiation of oral steroids. Intraocular inflammation and SRD rapidly resolved, with visual acuity reaching 20/20 in both eyes, after 3 weeks. No recurrence of intraocular inflammation or sign of depigmentation was so far noticed, at 2 years of follow-up.Conclusion: Yellow fever vaccine may be a possible trigger for VKH.

RESUMO

ABSTRACT Ocular toxoplasmosis frequently presents as necrotizing retinochoroiditis and, less often, as peripapillary chorioretinitis and/or papillitis. The progression from papillitis to peripapillary retinochoroiditis has been rarely described. We report the case of a 52-year-old patient living in southern Brazil, who developed papillitis in the right eye and was treated with systemic corticosteroids (prednisone 0.6 mg/kg/day and pulse therapy with methylprednisolone 15 mg/kg/day, for 3 days). After 14 days, the patient developed peripapillary retinochoroiditis with vitritis and decreased visual acuity (20/60), and was immediately initiated on the classic oral treatment for toxoplasmosis, consisting of pyrimethamine (50 mg/day), sulfadiazine (4 g/day), folinic acid (15 mg every 3 days) and prednisone (0.6 mg/kg/day). The visual acuity of the right eye normalized after treatment (20/20), which lasted approximately 70 days, but scotomas were detected on visual field examination, especially in the lower nasal quadrant. Although two studies mentioned this presentation, our report emphasizes the possible manifestation of ocular toxoplasmosis as papillitis in the initial phase, with progression to peripapillary retinochoroiditis and permanent visual field defects, which justifies early treatment for toxoplasmosis in suspected cases, especially in endemic regions.

RESUMO A toxoplasmose ocular manifesta-se com maior frequência por um quadro de retinocoroidite necrotizante e, com menor frequência, por coriorretinite justapapilar e/ou papilite. A evolução de papilite para retinocoroidite justapapilar raramente foi descrita. Apresenta-se o relato de caso de uma paciente de 52 anos, habitante da Região Sul do Brasil, que iniciou com quadro de papilite em olho direito, sendo tratada com corticoides sistêmicos (prednisona 0,6/mg/kg ao dia e pulsoterapia com metilprednisolona 15mg/kg ao dia, por 3 dias), mas, após 14 dias, evoluiu para retinocoroidite justapapilar, com vitreíte e diminuição de acuidade visual (20/60), sendo imediatamente instituído o tratamento via oral clássico para toxoplasmose, com pirimetamina (50 mg ao dia), sulfadiazina (4 g ao dia) e ácido folínico (15 mg a cada 3 dias), e mantida a prednisona (0.6 mg/kg/dia). A acuidade visual do olho direito normalizou após o tratamento (20/20), que durou em torno de 70 dias, porém desenvolveu escotomas ao exame de campo visual, sobretudo de quadrante nasal inferior. Embora tenham sido encontrados dois trabalhos que mencionam essa forma de apresentação, o presente relato destaca-se por enfatizar a possibilidade de manifestação da toxoplasmose ocular por meio de papilite na fase inicial, que evolui com retinocoroidite justapapilar, causando defeito permanente de campo visual, justificando que se avalie a instituição de tratamento precoce para toxoplasmose dos casos suspeitos, sobretudo em região endêmica.

RESUMO

RESUMO Este trabalho visou evidenciar a importância da detecção precoce da coroidite interna punctata e destacar sua fisiopatologia inflamatória e possíveis diagnósticos diferenciais dentro das white dot syndromes. O destaque foi dado principalmente à coroidite multifocal e à panuveíte, ao se demonstrar sua epidemiologia peculiar em mulheres jovens, caracterizar sua apresentação clínica típica na fundoscopia e explorar as vantagens e as desvantagens de realizar os exames complementares que fazem parte da análise multimodal útil para o diagnóstico (especialmente a angiografia fluoresceínica, a tomografia de coerência óptica e a indocianina verde). Descreve-se o caso de uma mulher de 28 anos diagnosticada com coroidite interna punctata com membrana neovascular coroidal em olho direito. O tratamento foi realizado com injeção intravítrea de aflibercepte e corticoterapia sistêmica 1mg/kg ao dia. Este relato é importante por permitir debater o manejo da coroidite interna punctata durante a gestação e a decisão de realizar o tratamento mediante uma diversidade de opções terapêuticas.

ABSTRACT This work aimed to demonstrate the importance of early detection of punctate inner choroidopathy, highlighting the pathophysiology of inflammation and the differential diagnoses among white dot syndromes. Special attention was given to multifocal choroiditis and panuveitis, by demonstrating the peculiar epidemiology in young women, characterizing the typical clinical presentation in ophthalmoscopy, and exploring the advantages and disadvantages of performing the complementary examinations, which are part of the multimodal analysis useful for diagnosis (particularly fluorescein angiography, optical coherence tomography, and indocyanine green). We report the case of a 28-year-old female, diagnosed as punctate inner choroidopathy with choroidal [N.T. no título aparece subretinal = subrretiniana] neovascular membrane in the right eye. She was treated with intravitreal injection of aflibercept and systemic corticosteroid 1 mg/kg/day. This case report is important for addressing the management of punctate inner choroidopathy during pregnancy, and the decision to carry out treatment considering diverse therapeutic options.

RESUMO

PURPOSE: To describe retinal pigment epithelium (RPE) disease detected by fundus autofluorescence (FAF) imaging in eyes with idiopathic choroidal neovascularization (ICNV). METHODS: A retrospective review of patients seen during a 14-month period with the diagnosis of ICNV was performed to identify patients with RPE disease, defined as hypo or hyperautofluorescent lesions on FAF. The presence of ICNV was confirmed by clinical history, ophthalmoscopic examination, fluorescein angiography (FA), and spectral domain-optical coherence tomography (SD-OCT). The clinical diagnosis of an underlying inflammatory condition was based on the FAF appearance of multiple punched-out hyper or hypoautofluorescent spots in the retinal fundus. RESULTS: The mean age was 27 years (range, 21-33 years). Best-corrected visual acuity ranged from 20/25 to 20/200 with a median visual acuity of 20/80. Ten eyes of 8 patients presented RPE abnormalities on FAF. Of the 10 study eyes, ICNV was observed in 8 eyes. ICNV appeared as a type 2 neovascular membrane at the macular area on FA, and SD-OCT revealed neurosensory detachment in all study eyes. FAF demonstrated abnormalities of the RPE that were not appreciated on clinical examination or by other imaging modalities. CONCLUSIONS: FAF may reveal an underlying inflammatory condition in patients diagnosed as ICNV, modifying the diagnosis and management.

RESUMO

Diffuse unilateral subacute neuroretinitis (DUSN) is an ocular infectious disease that can lead to severe visual impairment and blindness. It usually occurs in healthy young individuals and depending on the stage of the disease, it may present as vitritis, multifocal gray-white lesions in the outer retina, and derangement of the retinal pigment epithelium, narrowing of the retinal vessels and optic atrophy. Parasites of different sizes and species have been proposed as the etiologic agent of DUSN, including Ancylostoma caninum, Toxocara canis, and others. Thus, it is hypothesized that different infectious worms may be considered as the likely cause of both an autoimmune and toxic form of nematode retinopathy. Because serologic testing is variable, the definitive diagnosis is made when clinical characteristics of DUSN are found in conjunction with an intraocular worm. Ancillary tests can assist in the differential diagnosis when the nematode cannot be visualized, such as fluorescein and indocyanine green angiography, electrophysiological tests, visual field studies, and more recently, optical coherence tomography angiography. Cases in which the worm can be identified, it is defined as confirmed DUSN, and eyes with the typical clinical features but without identification of the worm should be classified as presumed DUSN. In confirmed DUSN, the classic treatment is directly photocoagulation of the worm; however, it can only be visualized in 30% (to 40%) of cases. Treatment of presumed DUSN cases with high-dose oral albendazole has shown encouraging results. However, perhaps due to the disease's rarity or its underdiagnosis, there are no studies comparing current treatment modalities in both presumed and confirmed DUSN. Due to the possibility of this disease being, in part, autoimmune nematode retinopathy, corticosteroids associated with both albendazole or laser therapy, could be in any way beneficial. Thus, further comparative studies are necessary to elucidate the best treatment for this potentially blinding disease.

RESUMO

BACKGROUND: Ocular involvement in AIDS patients is a common event mainly caused by inflammation or infection. Despite the high prevalence rate of cryptococcosis in these individuals, ocular features have been occasionally described. CASE REPORT: A 20-year-old Brazilian female with HIV infection recently diagnosed was admitted with a respiratory profile presumptively diagnosed as Pneumocystis jirovecii pneumonia; an ophthalmologic exam suggested choroiditis by this agent as well. She was complaining of headaches and blurred vision which led to cryptococcal meningitis diagnosis by a CSF positive India ink stain and Cryptococcus neoformans positive culture. Despite therapy based on amphotericin B plus fluconazole, her clinical state progressively worsened and the patient died one week later. At necropsy, disseminated cryptococcal infection was evidenced in several organs including eyes, which presented bilateral chorioretinitis. CONCLUSIONS: Cryptococcal ocular involvement in AIDS patients has been occasionally proved among the cases already reported. Thus, the post mortem exam is still pivotal to improve the quality of the clinical diagnosis, especially in limited-resource settings.

RESUMO

PURPOSE: To report a case of multifocal choroiditis (MC) that has relapsed as choroidal neovascularization in the contralateral eye followed by a mixed aspect of multiple evanescent white dot syndrome (MEWDS) and MC. METHODS: Retrospective case report and literature review. The clinical findings were documented by fluorescein angiography, optical coherence tomography, and optical coherence tomography angiography (OCT-A). RESULTS: The authors describe the case of a 39-year-old woman with prior ocular history of presumed MEWDS in her left eye, which developed into MC 7 years later in the same eye and 11 years later in the right eye, starting as choroidal neovascularization and developing into MEWDS. OCT-A showed neovessel in a supposedly active MC area outside the macular region in right and left eyes. OCT showed increased choroidal thickness in both eyes and a choroidal neovascularization in the right eye, treated using anti- VEGF therapy. CONCLUSION: This case corroborates the proximity of some inflammatory diseases such as MC and MEWDS. OCT-A has opened new horizons for the better understanding of some retinal diseases by providing more thorough and promising morphological analyses using enhanced tools.
