Neurorretinitis bilateral y nefritis lúpica membranosa: dos manifestaciones infrecuentes en el lupus juvenil / Bilateral neuroretinitis and membranous lupus nephritis: 2 infrequent manifestations in juvenile lupus

Joven de 15 años, previamente sana, se presentó con dolor abdominal, vómitos, diarrea, eritema malar, edema palpebral y en miembros inferiores, artralgias, rigidez matinal y visión borrosa bilateral. Estudios de laboratorio y por imágenes junto con la clínica permitieron realizar el diagnóstico de síndrome nefrótico secundario a lupus eritematoso sistémico. Al examen oftalmológico se constató 8/10 de visión en ambos ojos y edema de papila bilateral con estrella macular parcial, hallazgos compatibles con una neurorretinitis bilateral. La biopsia renal estableció el diagnóstico de nefritis lúpica membranosa. Se inició tratamiento inmunosupresor, con mejoría clínica gradual. Si bien el lupus eritematoso sistémico con nefritis lúpica membranosa y neurorretinitis es una asociación muy infrecuente, frente a un paciente con neurorretinitis bilateral debemos considerar el lupus eritematoso sistémico dentro de los diagnósticos diferenciales (AU)

Fifteen-year-old female patient, previously healthy, referred to our center for presenting abdominal pain, vomiting, diarrhea, malar erythema, palpebral and lower limb edema, arthralgia, morning stiffness and bilateral blurred vision. Laboratory and imaging studies together with the clinic allowed the diagnosis of nephrotic syndrome secondary to systemic lupus erythematosus. Ophthalmology examination revealed a visual acuity of 8/10 in both eyes and bilateral disc edema with partial macular star, findings compatible with bilateral neuroretinitis. Renal biopsy established the diagnosis of membranous lupus nephritis. Immunosuppressive treatment was started, obtaining gradual clinical improvement. Although systemic lupus erythematosus with membranous lupus nephritis and neuroretinitis is a very infrequent association, when faced with a patient with bilateral neuroretinitis, we must consider systemic lupus erythematosus within the differential diagnoses (AU)

Alteraciones oftalmológicas en pacientes con COVID-19 / Ophthalmologic Alterations in Patients with COVID-19

Introducción: Las alteraciones oftalmológicas asociadas al SARS-CoV-2 se pueden clasificar como efectos directos del virus, por reacción inmunológica o por la vacunación. Objetivo: Describir las alteraciones oftalmológicas en pacientes con COVID-19. Métodos: Se presenta una serie de casos con diagnóstico clínico y serológico de COVID-19 en el curso de la enfermedad, posterior a esta o por la vacunación. Fueron estudiados 7 casos (4 mujeres y 3 hombres), que acudieron de forma consecutiva a la consulta de Neuroftalmología del Hospital "Hermanos Ameijeiras" (HHA), remitidos por especialistas que evalúan el protocolo de casos "Pos-COVID-19" en esta institución con las siguientes alteraciones: neurorretinitis (NR), papilitis (P), uveítis y papilitis (U-P), membrana epirretiniana (MER) y parálisis facial periférica (PFP), en el periodo de agosto a noviembre de 2021. Resultados: La edad promedio fue de 44 años. La NR, P y MER unilateral predominaron en la serie estudiada. La etiología inmunológica fue la más frecuente. Los síntomas y signos referidos por los pacientes fueron: disminución visual y déficit en la visión de los colores. Los resultados terapéuticos no fueron satisfactorios en los casos 1 y 6, con un tiempo de evolución prolongado, desde el inicio de los síntomas hasta el diagnóstico y tratamiento con esteroides y vitaminas del complejo B. Conclusiones: Existe una asociación entre las enfermedades oftalmológicas encontradas en pacientes jóvenes con antecedentes de padecer la COVID-19 o relacionado con la vacunación. La efectividad terapéutica estuvo condicionada por el tiempo de evolución de la enfermedad(AU)

Introduction: Ophthalmologic alterations associated with SARS-CoV-2 can be classified as direct effects of the virus, by immunologic reaction or by vaccination. Objective: To describe the ophthalmologic alterations in patients with COVID-19. Methods: A series of cases with clinical and serologic diagnosis of COVID-19 during the course of the disease, after the disease or after vaccination is presented. Seven cases were studied (4 women and 3 men), who consecutively attended the Neurophthalmology Consultation of the "Hermanos Ameijeiras" Hospital (HHA), referred by specialists who evaluate the "Post-COVID-19" case protocol in this institution with the following alterations: neuroretinitis (NR), papillitis (P), uveitis and papillitis (U-P), epiretinal membrane (MER) and peripheral facial palsy (PFP), in the period from August to November 2021. Results: The average age was 44 years. NR, P and unilateral MER predominated in the series studied. Immunologic etiology was the most frequent. The symptoms and signs referred by the patients were visual impairment and color vision deficit. Therapeutic results were not satisfactory in cases 1 and 6, with a prolonged evolution time, from the onset of symptoms to diagnosis and treatment with steroids and B-complex vitamins. Conclusions: There is an association between the ophthalmologic diseases found in young patients with a history of suffering from COVID-19 or related to vaccination. Therapeutic effectiveness was conditioned by the time of evolution of the disease(AU)

Neurorretinitis por Bartonella henselae en un adolescente / Bartonella henselae neuroretinitis in an adolescent

La neurorretinitis como manifestación de la enfermedad por arañazo de gato se presenta en el 1-2 % de los pacientes con afecciones oculares porBartonella henselae. Las manifestaciones oculares suelen suceder a las sistémicas, aunque pueden aparecer en ausencia de estas. La presencia de exudado macular en forma de estrella es característico y sugestivo de dicha infección. Se presenta el caso de un paciente de 14 años de edad, previamente sano, con disminución de la agudeza visual de 15 días de evolución, que ingresó por sospecha de neuritis óptica izquierda con edema de papila. El seguimiento oftalmológico reveló la aparición de la lesión característica en "estrella macular" que permitió arribar al diagnóstico de infección por B. henselae, confirmándose luego con serología positiva

Neurorretinitis as a manifestation of cat scratch disease occurs in 1-2 % of patients with Bartonella Henselae eye disease. Ocular manifestations tend to follow systemic ones, although they can appear in their absence. The presence of star-shaped macular exudate is characteristic and suggestive of this infection. We report a case of a 14-year-old healthy boy, with 15 days of decreased visual acuity, who was admitted for suspected left optic neuritis with papilledema. Ophthalmological examination revealed the characteristic "macular star" that led to the diagnosis of infection by Bartonella Henselae, later confirmed by positive serology.

Neurorretinitis por Bartonella henselae en Gipuzkoa, 2014-2019 / Neuroretinitis caused by Bartonella henselae in Gipuzkoa, 2014-2019

Introducción: Bartonella henselae causa la enfermedad por arañazo de gato (EAG), transmitida por arañazo o mordedura de gato, su principal reservorio. En ocasiones produce neuritis óptica o neurorretinitis.Objetivo: Revisar estas dolencias en Gipuzkoa (España), 2014-2019. Métodos: Revisión retrospectiva de registros serológicos y clínicos, seleccionando aquellos con manifestaciones clínicas compatibles, contacto con gatos y serología positiva para B. henselae (IFI-IgG≥1/256). Resultados: Sesenta y cuatro pacientes presentaron EAG; entre estos, uno tenía neuritis óptica y 3, neurorretinitis (4/64, 6,3%). En 3 casos un cuadro pseudogripal precedió a los síntomas oculares; 2 presentaron pérdida de agudeza visual al alta, a pesar del tratamiento prolongado con antibióticos y corticoides. Conclusión: La neuritis óptica y la neurorretinitis por B. henselae son complicaciones graves que presentan una incidencia no despreciable entre los pacientes con EAG de Gipuzkoa. Recomendamos descartar la EAG en pacientes con síntomas de neuritis óptica o neurorretinitis (pérdida brusca de visión, etc.) y contacto con gatos.(AU)

Introduction: Bartonella henselae causes cat scratch disease (CSD), spread by a cat scratch or bite. Cats are its main reservoir. This sometimes results in optic neuritis or neuroretinitis. Objective: To review these conditions in Gipuzkoa (Spain), 2014-2019. Methods: A retrospective review of serology and clinical records, selecting those with consistent clinical signs, contact with cats and positive serology for B. henselae (IgG-IFA≥1/256). Results: Sixty-four patients had CSD. Of these, one had optic neuritis and 3 had neuroretinitis (4/64; 6.3%). In 3 patients, flu-like symptoms preceded eye symptoms. Two suffered from loss of visual acuity at discharge, despite prolonged treatment with antibiotics and corticosteroids. Conclusion: Optic neuritis and neuroretinitis caused by B. henselae are severe complications with a non-negligible incidence among patients with CSD in Gipuzkoa. We recommend ruling out CSD in patients with symptoms of optic neuritis or neuroretinitis (sudden vision loss, etc.) and contact with cats.(AU)

Infección atípica y neurorretinitis por Bartonella henselae en una unidad de hospitalización pediátrica: comunicación de tres casos / Bartonella henselae with atypical infection and neuroretinitis in a pediatric unit: report of three cases

Resumen Bartonella henselae es el agente etiológico de la enfermedad por arañazo de gato (EAG), infección endémica en Chile. Típicamente se presenta como una linfadenopatía regional autolimitada y menos frecuentemente con compromiso sistémico y manifestaciones extraganglionares: en hígado, bazo, hueso, ojo, entre otros. Se presentan tres casos de infección atípica por Bartonella henselae en las que se evidenció compromiso ocular, manifestado como una neurorretinitis. Esta revisión destaca la importancia de la búsqueda activa de complicaciones oculares en pacientes con compromiso sistémico por Bartonella henselae, implicando un cambio en el tratamiento y pronóstico de la enfermedad.

Abstract Bartonella henselae is cat scratch disease's etiological agent, which is considered an endemic infection in Chile. It typically presents as a self-limited regional lymphadenopathy and less frequently with systemic involvement and extranodal or atypical manifestations: hepatosplenic, ocular or musculoskeletal involvement, among others. We present three cases of atypical cat scratch disease with ocular compromise, as neurorretinitis. This review highlights the importance of the active search for ocular complications in patients with disseminated cat scratch disease, leading to possible change in treatment and prognosis of the disease.

About 3 cases of post-acute retinopathy of chikungunya fever. / A propósito de 3 casos con retinopatía posterior a fase aguda de fiebre por chikungunya.

A descriptive study is presented on a case series of 3 patients, with IgM an IgG serology diagnosis of Chikungunya in whom other metabolic, autoimmune and infectious diseases were ruled out. They presented with other ocular manifestations with vascular changes and inflammatory characteristics. They were treated at the Retinovascular and Retinal and Vitreous clinics at the "Dr. Rodolfo Robles Valverde Hospital" and "Benemérito Comité Pro-ciegos y Sordos" in Guatemala City during 2019. Guatemala is a country with a high prevalence of vector-borne diseases, including chikungunya. In recent years cases of this disease has increased in recent years, and complications are currently seen more frequently. Within these complications, there have been reports of cases of optic neuritis, iridocyclitis, episcleritis, retinitis, uveitis, and blood dyscrasia that can affect the retina. It is important to consider these as an important differential diagnosis of ocular vascular alterations.

Neurorretinitis por Bartonella henselae. Reporte de caso y revisión de la literatura / Bartonella henselae neuroretinitis. A case report and literature review

Introducción: La Enfermedad por Arañazo de Gato (EAG) es una enfermedad zoonótica causada por Bartonella henselae, un bacilo gram negativopleomórfi co. Sus manifestaciones clínicas varían de acuerdo a la respuesta inmunológica instaurada por el huésped, pudiendo ser de tipo granulomatosa o angioproliferativa. El diagnóstico es clínico, sin embargo, se utiliza la serología e imágenes multimodales para la confi rmación diagnóstica y el seguimiento de la misma. Objetivo: Describir el caso de una paciente joven que presenta aftasorales recurrentes como única manifestación sistémica de EAG asociado a neurorretinitis unilateral, quien es manejada con antibiótico en combinación con corticoide sistémico. Diseño del estudio: Reporte de caso Resumen del caso: Paciente con antecedente de contacto directo con gatoscachorros y aft as orales recurrentes; presenta disminución de la agudeza visual en ojo izquierdo. Al examen oft almológico presenta papilitis, hemorragias intrarretinianas y presencia de cicatriz coriorretiniana en ojo contralateral. Ante los hallazgos descritos se indica manejo antibiótico por sospecha de infección por toxoplasmosis, sin embargo, presenta evolución tórpida. Se realizan estudios complementarios que evidencian desprendimiento seroso de retina con evolución a estrella macular, por lo que se modifi ca el esquema antibiótico a los 15 días, presentando mejoría de la sintomatología. Conclusión: La neurorretinitis secundaria a enfermedad por arañazo de gato es una entidad subdiagnosticada en nuestro medio, lo que hace importante indagar sobre antecedentes de contacto con felinos y los posibles diagnósticos diferenciales. Es esencial establecer esquemas de manejo antibiótico basados en la literatura ante la sospecha de la enfermedad para evitar sus posibles complicaciones.

Background: Cat Scratch Disease is a zoonotic disease caused by Bartonella henselae, a pleomorphic gram negative bacillus. Its clinical manifestations vary according to the immune response established by the host, it may be a granulomatous or angioproliferative type. Th e diagnosis is based on clinical fi ndings, however, serology and multimodal images are used for diagnosis confi rmation and monitoring. Objective: To describe the case of a young patient, who presents recurrent oral thrush as the only systemic manifestation of CSD associated with unilateral neuroretinitis, who is managed with antibiotic in combination with systemic corticosteroid. Study Design: Case report. Case summary: Patient with a history of direct contact with puppy cats and recurrent oral thrush; presents decreased visual acuity in the left eye. During ophthalmological examination, she presents papillitis, intraretinal hemorrhages and the presence of a chorioretinal scar in the contralateral eye. Given the fi ndings described, antibiotic management is indicated due to suspected toxoplasmosis infection, however, she presents a torpid evolution. Th e complementary tests show serous retinal detachment with evolution to macular star, thus treatment regimen is modifi ed aft er 15 days with secondary symptoms improvement. Conclusion: Neuroretinitis secondary to cat scratch disease is an underdiagnosed entity in our setting, which makes it important to inquire about feline contact history and possible diff erential diagnoses. It is essential to establish antibiotic management schemes based on the literature when the disease is suspected to avoid its possible complications

Leber's idiopathic stellate neuroretinitis: diagnostic and therapeutic conflicts. / Neurorretinitis estrellada idiopática de Leber: conflictos diagnósticos y terapéuticos.

Three cases of patients with decreased visual acuity and papillitis at onset with subsequent macular star development after a few weeks are presented. Complementary tests were unremarkable in all included patients. Based on this clinical context, they were diagnosed with Leber's idiopathic stellate neuroretinitis, were treated with corticosteroids, as well as with antibiotics in 2cases. All patients showed favourable outcomes, although signs of papillary atrophy were observed in the affected eyes. Leber's idiopathic stellate neuroretinitis diagnosis can be challenging due to the wide spectrum of conditions that have to be ruled out. In addition, macular star may appear later on, which should not exclude its diagnosis. Use of antibiotics and/or corticosteroids is controversial considering its benign nature, but should be considered in selected severe cases. Moreover, the routine use of complementary tests should be carefully evaluated, mainly those that can be aggressive and/or expensive, which should be rationally used.

Papillitis and neuroretinitis of tuberculous etiology. / Papilitis y neurorretinitis de etiología tuberculosa.

A 57-year-old man with miliary tuberculosis reported visual loss in his right eye, a month after starting a four-drug antituberculous treatment regimen. On exploration, an inferior segmental optic disc edema was objectived and it was attributed to ischemic aetiology. Ethambutol was withdrawn and 60mg of oral prednisone daily were given with a tapering dosage. One and a half months later, he presented a sudden loss of vision in his left eye. In fundoscopy, a papillary edema accompanied by a foveal neurosensory detachment was observed but with no more accompanying uveitic signs. Treatment was intensified with moxifloxacin and corticosteroids were reduced, showing a resolution of the macular detachment but with optic atrophy. Isolated tuberculous involvement of the optic nerve may possible in the context of miliary tuberculosis. In this case, the adopted therapeutic approach to the initial papillitis, which was interpreted as ischemic, could favour the appearance of a neuroretinitis in the fellow eye.

Case series of ocular involvement due to dengue. First reported cases in Guatemala. / Serie de casos de afección ocular por dengue. Primeros casos publicados en Guatemala.

OBJECTIVE: Describe the ocular findings of a case series of 8 patients with a diagnosis of dengue. MATERIALS AND METHODS: Review of clinical records and interviews with patients during outpatient visits, after informed consent was obtained and following the ethical standards of the Helsinki declaration. The patients were diagnosed with diagnosis by IgM / IgG dengue serology in whom ocular involvement was identified, between January and October 2017 in Retinal-vascular clinic of the "Dr. Rodolfo Robles Valverde Hospital", Guatemala. RESULTS: The 8 patients, 5 men and 3 women from rural areas in Guatemala, were diagnosed with dengue by IgM / IgG serology with associated ocular involvement. The mean age was 32.3 years, with the oldest being 45 years old and the youngest being 20 years old. The ocular manifestations identified were, 4 neuroretinitis, 3 venous obstructions, 3 maculopathies, 2 serous detachments, 1 episcleritis, and 1 vasculitis. Two patients developed optic atrophy after resolving the neuroretinitis, and 1 developed peri-foveal scarring after the maculopathy. The ocular involvement was resolved in all patients after treatment, with an improvement in visual acuity, although in some cases damage to the visual field developed as a sequela of neuroretinitis. CONCLUSION: It is necessary to consider dengue as an important differential diagnosis in an endemic country such as Guatemala. There are a large number of ocular manifestations due to direct involvement, as well as by an immune system reaction, and thus avoid considering the different ocular manifestations as idiopathic, or due to a different condition.

Aspectos epidemiológicos, diagnósticos y de tratamiento de la toxocariasis ocular / Epidemiological aspects, diagnosis, and treatment of ocular toxocariasis

Objetivo: Analizar la epidemiología, los métodos diagnósticos y los abordajes terapéuticos de la toxocariasis ocular en el Hospital de Pediatría Juan P. Garrahan. Materiales y métodos: Se realizó un estudio observacional y descriptivo en el Servicio de Oftalmología del Hospital de Pediatría J. P. Garrahan analizándose en forma retrospectiva los pacientes con ELISA positivo para IgG anti-Toxocara canis vistos en el laboratorio de Parasitología y evaluados en el servicio de Oftalmología entre enero 2006 a junio de 2013. Resultados: Se incluyeron en el estudio 301 pacientes de los cuales 95 (31,5%), presentaron diagnóstico de toxocariasis ocular (59 niños y 36 niñas) y 206 no tuvieron afección oftálmica por Toxocara canis. El 100% de los pacientes con afección ocular por el parásito presentó algún grado de alteración de la visión. Las formas de toxocariasis ocular que se registraron son: granuloma periférico aislado en 12 pacientes (12,6%), granuloma periférico con pliegue unido a papila en 36 (37,9%), granuloma de polo posterior en 7 (7,4%), endoftalmitis crónica en 3 (3,2%), neurorretinitis subaguda unilateral difusa en 2 (2,1%), desprendimiento de retina en 23 (24,2%) y en 12 (12,6%) forma indeterminada. Conclusiones: El diagnóstico de la toxocariasis ocular en la infancia tiende a hacerse en forma tardía ya que los niños pequeños no suelen manifestar a los padres la disminución visual de un ojo siendo el motivo de consulta más frecuente el estrabismo. El diagnóstico es clínico. La forma oftalmoscópica de presentación más frecuente en nuestro estudio fue el granuloma periférico con pliegue falciforme unido a papila. Oftalmoscopicamente la toxocariasis ocular puede presentarse de formas sumamente disímiles, lo cual hace dificultoso su diagnóstico y obliga a pensar siempre en éste en un niño que presenta inflamación intraocular unilateral. El uso de antiparasitarios en nuestros pacientes fue irregular (AU)

Objective: To assess the epidemiology, diagnostic methods, and treatment approach in ocular toxocariasis at the Pediatric Hospital Juan P. Garrahan. Material and methods: An observational descriptive study was conducted at the Department of Ophthalmology of the Pediatric Hospital Juan P. Garrahan. Patients with a positive ELISA for anti-Toxocara canis IgG seen at the laboratory of parasitology and evaluated at the Department of Ophthalmology between January 2006 and June 2013 were retrospectively analyzed. Results: 301 patients were included in the study of whom 95 (31.5%) had a diagnosis of ocular toxocariasis (59 boys and 36 girls) and in 206 the eyes were not affected by toxocariasis. All patients with ocular toxocariasis had some degree of visual impairment. The forms of ocular toxocariasis found were: isolated peripheral granuloma in 12 patients (12.6%), peripheral granuloma with the fold united to the papilla in 36 (37.9%), posterior pole granuloma in 7 (7.4%), chronic endophthalmitis 3 (3.2%), diffuse unilateral subacute neuroretinitis 2 (2.1%), retinal detachment in 23 (24.2%), and an indeterminate form in 12 (12.6%). Conclusions: The diagnosis of ocular toxocariasis in childhood is often late as children are not able to report vision loss to their parents. Strabism is the most common reason for consult. The diagnosis is clinical. The most frequent ophthalmoscopic presentation was peripheral granuloma with a falciform fold attached to the papilla. Ophthalmoscopically, ocular toxocariasis may present heterogeneously, resulting in a difficult diagnosis. The disease should always be suspected in a child with unilateral intraocular inflammation. The use of antiparasitic agents was variable in our patients (AU)

Toxoplasmosis ocular. Descripción de tres pacientes con presentación atípica / Ocular toxoplasmosis. Description of three patients with an atypical presentation.

Objetivo: Describir una forma de presentación atípica de toxoplasmosis ocular, enfatizando la importancia de la jerarquización de los hallazgos clínicos y las limitaciones de la serología para realizar un diagnóstico temprano. Pacientes y Métodos: Estudio retrospectivo y descriptivo de tres casos clínicos de toxoplasmosis ocular activa, con presentación atípica (compromiso del nervio óptico), derivados al Servicio de Oftalmología del Hospital J. P. Garrahan en el periodo comprendido entre 2007 y 2010. Resultados: En los tres casos presentados la sospecha clínica de toxoplasmosis ocular no se correlacionó con evidencia serológica de infección reciente. En un caso, la terapéutica específica temprana, basada en la sospecha clínica, resultó en una excelente recuperación funcional. Un tratamiento tardío puede interferir en el resultado visual. Conclusiones: Basados en los hallazgos clínicos y la alta sospecha de esta patología debe iniciarse el tratamiento específico sin esperar que los resultados serológicos la confirmen. Eventualmente, la mejoría clínica confirmara el diagnóstico. El comportamiento de los títulos de anticuerpos en el curso de la enfermedad ocular no siempre es confiable, y en muchos casos retrasa el comienzo de la terapéutica con la consiguiente mala rehabilitación visual de estos pacientes (AU)

Objective: To describe an atypical presentation of ocular toxoplasmosis, emphasizing the importance of clinical findings and the limitations of serology in the early diagnosis. Patients and Methods: A retrospective, descriptive study was conducted of three cases with active ocular toxoplasmosis with an atypical presentation (optic nerve involvement), referred to the Department of Ophthalmology of Hospital J. P. Garrahan between 2007 and 2010. Results: In the three cases presented here clinical suspicion of ocular toxoplasmosis did not correlate with serological evidence of a recent infection. In one case, early treatment, based on clinical suspicion, resulted in excellent functional recovery. Late management may compromise visual outcome. Conclusions: Based on clinical findings and suspicion of the pathology, specific treatment should be started without waiting for serological confirmation. Eventually, clinical improvement will confirm the diagnosis. The behavior of antibody titres in the course of the ocular disease is not always reliable and often delays treatment initiation with subsequent difficulties in the visual rehabilitation of these patients (AU)

[Early treatment of idiopathic vasculitis, aneurysms and neuroretinitis (IRVAN). A case report]. / Tratamiento precoz de vasculitis idiopática, aneurismas y retinitis (IRVAN). A propósito de un caso.

CASE REPORT: A 55 year old woman presented with retinal vasculitis, multiple aneurysms, macular exudation and widespread retinal nonperfusion and was diagnosed with IRVAN. She was treated with panretinal laser photocoagulation. After 3 years of follow up visual acuity remains stable and there are no complications due to ischaemic sequelae. DISCUSSION: IRVAN syndrome with neovascularisation can progress rapidly despite laser treatment. Panretinal laser photocoagulation has to be considered in the early stages as it is effective in stopping the progression of ischaemia.
