Complejo anómalo vascular exudativo perifoveal (PEVAC) / Perifoveal exudative vascular anomalous complex (PEVAC)

Se presentan 3 casos de pacientes, con 66, 80 y 23años de edad, que presentaron una pérdida de visión unilateral. La tomografía de coherencia óptica (OCT) mostró edema macular junto con una lesión redondeada de pared hiperreflectiva y la angiografía con fluoresceína (AFG) de dos de ellos, dilataciones aneurismáticas perifoveales hiperfluorescentes con exudación. Ninguno de los casos mostró respuesta al tratamiento tras un año de seguimiento, diagnosticándose finalmente de complejo anómalo vascular exudativo perifoveal (PEVAC) (AU)

We present three cases of patients aged 66, 80 and 23, who presented unilateral vision loss. Optical coherence tomography (OCT) in all of them showed macular oedema and a rounded lesion with hyper-reflective wall, and fluorescein angiography (FAG) in two of them showed hyperfluorescent perifoveal aneurysmal dilations with exudation. None of the cases showed response to treatment after one year of follow-up, finally being diagnosed with perifoveal exudative vascular anomalous complex (PEVAC) (AU)

Two case reports of acute zonal occult outer retinopathy (AZOOR): Importance of multimodal diagnosis.

A presentation is made of two cases of acute zonal occult outer retinopathy (AZOOR); one a young man of 19 years, and the other a 42-year-old woman. The young man complained of unilateral scotoma and photopsia. The woman presented with bilateral visual loss and photopsia. Multimodal imaging, including fundus photography, fluorescein angiography, fundus autofluorescence, spectral-domain optical coherence tomography, and visual field testing, supported the diagnosis of AZOOR. The differential diagnosis is complicated, since it has clinical features in common with other retinopathies. This means that it is essential to use modern imaging tests, especially those where the characteristic trizonal pattern is shown, such as in autofluorescence and OCT.

Dos casos de retinopatía externa oculta zonal aguda: importancia del diagnóstico multimodal / Two case reports of acute zonal occult outer retinopathy (AZOOR): importance of multimodal diagnosis

Presentamos dos casos de retinopatía externa oculta zonal aguda (AZOOR). Un varón joven de 19 años de edad y una mujer de 47 años. El varón joven presentó inicialmente clínica unilateral de escotoma centrocecal y fotopsias. La sintomatología inicial de la mujer fue disminución de visión y fotopsias bilaterales. Los estudios realizados mediante imagen multimodal con fotografías del fondo de ojo, angiografía fluoresceínica, autofluorescencia de fondo, tomografía de coherencia óptica de dominio espectral y pruebas de campo visual fueron consistentes con el diagnóstico de AZOOR. El diagnóstico diferencial de esta patología es complicado, ya que comparte datos clínicos con otras retinopatías, por lo que resulta imprescindible apoyarse en las pruebas de imagen disponibles hoy en día, prestando especial atención a aquellas donde puede verse el patrón trizonal característico, como son la autofluorescencia y la OCT (AU)

Paediatric Horner syndrome. A case series of 14 patients in a tertiary hospital.

BACKGROUND: Horner syndrome (HS) is characterised by the triad of upper eyelid ptosis, miosis, and facial anhidrosis. Due to its wide variety of causes, it can occur at any age, and is uncommon in paediatrics. The aetiology and diagnostic approach of paediatric HS (PHS) is controversial. OBJECTIVE: The purpose of this study is to describe the clinical characteristics of a 14 case series, focusing on the aetiology of HS and the clinical evolution the patients presented. METHODS: A retrospective observational study was conducted on patients under 14 years-old (enrolled between 1st January 2009 and 30th April 2020). Depending on the age at diagnosis (before or after the first 5 months of life), the study cases were divided into two groups: congenital or acquired. RESULTS: Fourteen patients, with a mean age of 8.5 months, were enrolled. The most frequent cause of PHS were tumours (6/14), with the most representative neoplasm being neuroblastoma (4/14). Of the acquired cases (8/14), the most frequent cause was iatrogenic (5/8), mainly secondary to cervical or thoracic surgery. The main origin of congenital HS (6/14) was neuroblastoma (4/6), being the first manifestation of the disease in 50% of patients (2/4). CONCLUSION: HS may be the first sign of a major underlying disease, such as neuroblastoma. For this reason, children presenting with HS of unknown origin require imaging studies to exclude a life threatening disease. A thorough examination is essential for early diagnosis of these patients.

Chronic cytomegalovirus necrotizing retinitis in a patient with scleroderma and mixed connective tissue disease.

The case is presented of a 52-year-old woman with scleroderma, mixed connective tissue disease, and interstitial lung disease, who developed chronic cytomegalovirus necrotizing retinitis while on treatment with prednisone, mycophenolate, and hydroxychloroquine. Initially diagnosed as macular hole, the patient underwent a pars plana vitrectomy. Two months after surgery, due to progressive worsening, the diagnosis was made and treatment started (intravenous and intravitreal ganciclovir). The patient developed severe macular atrophy with final visual acuity of counting fingers. A chronic retinal necrosis can be caused by cytomegalovirus infection in non-HIV patients with partial immune dysfunction from other causes, characterized by a slowly progressive granular retinitis with occlusive vasculitis.

Síndrome de Horner pediátrico. A propósito de una serie de 14 casos en un hospital terciario / Paediatric Horner syndrome. A case series of 14 patients in a tertiary hospital

Antecedentes El síndrome de Horner (SH) se caracteriza por la triada de ptosis palpebral, miosis y anhidrosis facial. Debido a su amplia variedad de causas puede ocurrir en cualquier edad, siendo infrecuente en pediatría. La etiología y estudio diagnóstico del SH pediátrico (SHP) es motivo de controversia. ObjetivoDescribir las características clínicas de una serie de 14 niños diagnosticados de SH, incidiendo en la etiología del SH y en la evolución clínica que presentaron. Métodos Estudio observacional retrospectivo de pacientes menores de 14 años diagnosticados de SHP en nuestro centro entre el 01 de enero del 2009 y el 30 de abril del 2020. En función de la edad al diagnóstico, los casos se dividieron en congénitos (antes de los cinco meses) y adquiridos. Resultados Se reclutaron 14 pacientes, con una mediana de edad al diagnóstico de 8,5 meses. La causa más frecuente de SHP fue tumoral (6/14), siendo la neoplasia más representativa el neuroblastoma (4/14). De los casos adquiridos (8/14), la causa más frecuente fue iatrogénica (5/8), secundario a cirugía cérvico-torácica. La etiología principal del SH congénito (6/14) fue el neuroblastoma (4/6), siendo la primera manifestación clínica de la enfermedad en el 50% de los pacientes (2/4). Conclusiones El SH puede ser el primer signo de una enfermedad subyacente grave, como es el neuroblastoma. Por este motivo, es necesario realizar un adecuado estudio de extensión en todos los pacientes pediátricos diagnosticados de SH sin una causa clara atribuible. Es fundamental un examen riguroso para un diagnóstico precoz de estos pacientes (AU)

Retinitis necrosante crónica por citomegalovirus en una paciente con esclerodermia y enfermedad mixta del tejido conectivo / Chronic cytomegalovirus necrotising retinitis in a patient with scleroderma and mixed connective tissue disease

Mujer de 52 años de edad con esclerodermia, enfermedad mixta del tejido conectivo, enfermedad pulmonar intersticial y malnutrición severa a causa de la afectación esofágica de su enfermedad, en tratamiento con prednisona, micofenolato e hidroxicloroquina, que desarrolló una necrosis retiniana crónica por citomegalovirus. Inicialmente diagnosticada de agujero macular, se realizó una vitrectomía para su corrección. No fue hasta 2meses después de la intervención, como consecuencia del empeoramiento progresivo, cuando se realizó el diagnóstico y el comienzo del tratamiento con ganciclovir por vía intravenosa e intravítrea. La agudeza visual final fue de contar dedos, como consecuencia de una grave atrofia macular. En pacientes VIH negativos con inmunodeficiencia parcial por otras causas, puede desarrollarse una necrosis retiniana crónica por citomegalovirus, caracterizada por una necrosis granular lentamente progresiva acompañada de una vasculitis retiniana oclusiva (AU)
