RESUMO

PURPOSE: Central Serous Chorioretinopathy (CSCR) is a prevalent ocular disease classified in the pachychoroidal spectrum with an elevated morbidity. Although the pathogenesis is yet unclear, mineralocorticoid-mediated pathways seem to be implicated. Primary hyperaldosteronism (PA) is a relatively frequent, albeit underdiagnosed, cause of hypertension, and has a specific therapy. A previous study assessed the prevalence of CSCR-like signs in a cohort of patients diagnosed with PA and found signs in seven out of thirteen PA patients. The present study aims to study the contrary, screening for PA in a cohort of acute CSCR patients. METHODS: Between March 2017 and September 2018 all patients with acute CSCR were systematically referred to Endocrinology Department after complete ophthalmic evaluation was performed with visual acuity, spectral domain optical coherence tomography, fundus autofluorescence, fluorescein and indocyanine green angiography. The method applied for detection of PA was the 2-h 25 mg captopril challenge test (CCT). RESULTS: Of the nineteen patients screened, two of them had a CCT positive for PA (2-h plasma aldosterone/renin ratio > 50 and/or an aldosterone level of 130 pg/ml or higher), and were treated with mineralocorticoid receptor antagonists (MRA). No ophthalmic pattern was identified in them in terms of time to resolution, recurrences or features of the acute episode. The only differential feature in the fundus of PA patients was pathological arteriovenous crossings (AVC) as well as elevated BP levels. CONCLUSION: a high incidence of PA was found among acute CSCR patients. This preliminary study suggests a need for screening for PA in hypertensive CSCR patients in real clinical practice.

RESUMO

El hemangioma coroideo es un tumor vascular benigno dependiente de la circulación coroidea. Se distinguen 2tipos de lesiones: circunscrita, variante más frecuente, y difusa, asociada normalmente al síndrome de Sturge-Weber. El hemangioma coroideo circunscrito se presenta como una masa anaranjada que puede aparecer de manera asintomática, sin embargo, cuando produce síntomas, lo más frecuente es la disminución de la agudeza visual debido a un desprendimiento de retina neurosensorial. Debido a su carácter benigno solo deberían ser subsidiarios de tratamiento aquellos que produzcan síntomas. El conocimiento de esta enfermedad y su correcto diagnóstico diferencial es muy relevante para establecer el diagnóstico y tratamiento adecuado y evitar tratamientos innecesarios. En la actualidad existe una gran variedad de pruebas de imagen de diagnóstico multimodal que nos permiten identificar y realizar un seguimiento adecuado de este tumor. Además, en los últimos años, gracias al empleo de la terapia fotodinámica, se ha producido un cambio en el paradigma del tratamiento de estas lesiones, lo cual ha supuesto una mejora significativa en el pronóstico visual de estos pacientes. Esto se ha debido al empleo de la terapia fotodinámica, como tratamiento de elección para el hemangioma coroideo circunscrito (AU)


Choroidal hemangiomais a benign vascular tumor dependent on the choroid. Two types of lesions are distinguished: circumscribed, the most frequent variant, and diffuse, normally associated with Sturge-Weber syndrome. The circumscribed choroidal hemangioma appears as an orange mass that can present asymptomatically, however, when it produces symptoms, the most frequent is decreased visual acuity due to neurosensory retinal detachment. Due to its benign nature, only those that produce symptoms should be eligible for treatment. Knowledge of this pathology and its correct differential diagnosis is very relevant to establish the appropriate diagnosis and treatment, avoiding unnecessary treatments. There is currently a wide variety of multimodal diagnostic imaging tests that allow us to identify and adequately monitor this tumor. In addition, in recent years, there has been a change in the paradigm of the treatment of these tumors thanks to the use of photodinamic therapy, which has led to a significant improvement in the visual prognosis of these patients. This has been due to the use of photodynamic therapy as the treatment of choice for circumscribed choroidal hemangioma (AU)

RESUMO

Choroidal hemangioma (CH) is a benign vascular tumor dependent on the choroid. Two types of lesions are distinguished: circumscribed (CCH), the most frequent variant, and diffuse (DCH), normally associated with Sturge-Weber syndrome. HCC appears as an orange mass that can present asymptomatically, however, when it produces symptoms, the most frequent is decreased visual acuity due to neurosensory retinal detachment. Due to its benign nature, only those that produce symptoms should be eligible for treatment. Knowledge of this pathology and its correct differential diagnosis is very relevant to establish the appropriate diagnosis and treatment, avoiding unnecessary treatments. There is currently a wide variety of multimodal diagnostic imaging tests that allow us to identify and adequately monitor this tumor. In addition, in recent years, there has been a change in the paradigm of the treatment of these tumors thanks to the use of photodinamic therapy, which has led to a significant improvement in the visual prognosis of these patients. This has been due to the use of photodynamic therapy as the treatment of choice for HCC.

RESUMO

La retinosquisis ligada al cromosoma X (RLX) es una causa de degeneración retiniana que afecta a varones en edades tempranas. Los desórdenes ligados al cromosoma X clásicamente afectan sólo a varones. Presentamos el caso de una mujer de 10 años de edad, con el espectro completo de la patología. MAVC 0.7 AO. En la tomografía de coherencia óptica (TCO) presentaba alteración foveal bilateral de aspecto quístico. En el estudio genético se identifica la variante c.644A>T (p.Glu215Gly) en el gen RS1 en homocigosis, asociada a retinosquisis con modo de herencia recesiva ligada al X. La RXL es una condición que tiene una gran variedad en la severidad de la enfermedad y no existe correlación entre esta última y la progresión de la patología. La enfermedad ha sido descrita en un limitado número de mujeres principalmente en familias con alto grado de consanguinidad (AU)


X-linked retinoschisis (XLR) is a cause of retinal degeneration that affects males at an early age. X-linked disorders classically affect only males. We present the case of a 10-year-old female with the full spectrum of the pathology. BCVA 0.7 OU. Optical coherence tomography (OCT) showed bilateral foveal alteration with cystic appearance. The genetic study identified the variant c.644A>T (p.Glu215Gly) in the RS1 gene in homozygosis, associated with retinoschisis with X-linked recessive mode of inheritance. XLR is a condition that has a great variety in the severity of the disease and there is no correlation between the latter and the progression of the pathology. The disease has been described in a limited number of females mainly in families with high degree of consanguinity (AU)

RESUMO

AIM: To evaluate the perception of barriers in healthcare and the impact of intravitreal injections in patients with neovascular age-related macular degeneration (nAMD). METHODS: Cross-sectional study including 108 patients with nAMD in treatment with intravitreal injections. The patients answered a questionnaire with 26 questions (score from 1 to 5) divided in three sections: 1) the disease and its treatment with injections, 2) healthcare barriers and 3) new technologies. RESULTS: The mean age was 80.4 ±â€¯7.0 years and visual acuity (VA) was 75.2 ±â€¯12.4 letters. The main barriers in healthcare were long waiting times (72%), followed by other comorbidities (10%). Some 63% of patients have to wait between 3 and 5 h to attend their clinical visit. Significant anxiety due to the injections (2.8 ±â€¯1.3) was observed, being present in 71% of the cases the day before. A great fear of blindness and losing independence was observed (4.4 ±â€¯0.9 and 4.3 ±â€¯1.1), with no differences in relation to VA, age or sex (p ≥ 0.135). Moreover, 28% of the patients reported that it was quite or very difficult for them to attend the clinical visit, with 69% of the total showing great interest in having a diagnostic device at home. CONCLUSION: The nAMD and its treatment represent a significant burden on patients, among whom there is a great fear of blindness and of losing their independence, the main barrier being the long waiting time for the clinical visit.

RESUMO

Propósito Evaluar la percepción de las barreras en la asistencia sanitaria y del impacto de las inyecciones intravítreas en los pacientes con degeneración macular asociada a la edad neovascular (DMAEn). Métodos Estudio transversal de 108 pacientes con DMAEn en tratamiento con inyecciones intravítreas mediante un cuestionario de 26 preguntas (puntuación del 1 al 5) divididas en 3 bloques: 1)enfermedad y su tratamiento con inyecciones; 2)barreras en la asistencia sanitaria, y 3)nuevas tecnologías. Resultados La edad media fue 80,4±7,0 años y la agudeza visual (AV) de 75,2±12,4 letras. Las principales barreras en la asistencia sanitaria fueron los largos tiempos de espera en consulta (72%), seguida por otras comorbilidades (10%). El 63% de los pacientes dedican entre 3 y 5h para acudir a la consulta. Se apreció una ansiedad notable debida a las inyecciones (2,8±1,3), estando presente en el 71% el día antes. Se observó un gran miedo a la ceguera y a dejar de ser independientes (4,4±0,9 y 4,3±1,1), sin existir diferencias en relación con la AV, la edad o el sexo (p≥0,135). El 28% de los pacientes refieren que les cuesta bastante o mucho la asistencia a consulta, presentando el 69% del total un gran interés en tener un aparato diagnóstico en el domicilio. Conclusiones La DMAEn y su tratamiento suponen una importante carga asistencial para los pacientes, existiendo un gran miedo a la ceguera y a perder su independencia, siendo la principal barrera el largo tiempo de espera en consulta (AU)

RESUMO

PURPOSE: To assess the vision-related quality of life and the depression and anxiety rates in patients with neovascular Age-Related Macular Degeneration (nAMD). METHODS: A cross-sectional study of patients with nAMD treated with intravitreal injections was performed. The patients completed two validated questionnaires: the Visual Functioning Questionnaire (VFQ-25, score from 0 to 100), and the Hospital Anxiety and Depression Scale (HADS) questionnaire. Age, gender and visual acuity (VA) in the Early Treatment Diabetic Retinopathy Study (ETDRS) scale was registered. RESULTS: Fifty-five patients with nAMD participated with a mean age of 80.9 ± 6.6 years-old (range 67-93) and a mean VA in the best eye of 73.5 ± 12.7 letters (range 44-95). The global VFQ-25 mean score was 57.4 ± 21.9 being 38.9 ± 13.2 for the general vision and 42.0 ± 19.5 for the general health. VA in the best eye was associated with the global score of the VFQ-25 scale (R = 0.608; P < .001), but no correlation was observed with general health (P = .936). In the HADS scale, 26.9% and 25.5% of patients had symptoms of depression and anxiety respectively. A negative correlation was found between the HADS and VFQ-25 scales for the general vision score (R = -0.438). CONCLUSION: This study elucidates the impact of vision impairment and the visual functioning in nAMD, describing an important rate of depression and anxiety symptoms.

RESUMO

Propósito Evaluar la calidad de vida relacionada con la visión, así como la presecia de síntomas de depresión y ansiedad en los pacientes con degeneración macular asociada a la edad neovascular (DMAEn). Métodos Se realizó un estudio transversal de pacientes con DMAEn en tratamiento con inyecciones intravítreas de antiangiogénicos. Los pacientes realizaron 2 cuestionarios validados: el cuestionario de función visual (VFQ-25, cuya puntuación varía de 0 a 100) y la Escala hospitalaria de ansiedad y depresión (HADS). Se registraron la edad, el sexo y la agudeza visual (AV) en la escala Early Treatment Diabetic Retinopathy Study. Resultado Se incluyeron 55 pacientes con DMAEn con una edad de 80,9±6,6 años (rango 67 a 93) y una AV en el mejor ojo de 73,5±12,7 letras (rango 44 a 95). La puntuación global media en el VFQ-25 fue de 57,4±21,9, siendo 38,9±13,2 para la visión general y 42,0±19,5 para la salud general. La AV se correlacionó con la puntuación global de la escala VFQ-25 (R=0,608; p<0,001), pero no con la salud general (p=0,936). Mediante la escala HADS se detectó un 27,2% y un 25,5% de pacientes con síntomas de depresión y ansiedad respectivamente. Se observó una correlación negativa entre las puntuaciones del HADS y VFQ-25 para el dominio de visión general (R=–0,438). Conclusiones Este estudio muestra el impacto en la calidad de vida y función visual en los pacientes con DMAE neovascular, presentando en un porcentaje considerable de los casos síntomas de depresión y ansiedad (AU)

RESUMO

Introducción: El hamartoma astrocítico retiniano es un tumor benigno generalmente asintomático, asociado o no al complejo de esclerosis tuberosa. La hemorragia vítrea es una rara presentación. Caso clínico: Paciente de 12 años acude por visión de "una mancha negra" en el hemicampo temporal superior del ojo derecho. Refiere un episodio similar hace 2 años. En lámpara de hendidura el polo anterior es normal. En la funduscopia se evidencia una masa de aspecto translúcido blanco-amarillenta peripapilar y hemorragia vítrea peripapilar. Las características de la autofluorescencia, angiografía fluoresceínica y la tomografía de coherencia óptica son compatibles con un hamartoma astrocítico retiniano. Los estudios complementarios (serología y radiografías) y examen clínico completo descartan afectación sistémica asociada. Se procedió a un seguimiento estrecho del paciente hasta reabsorción de la hemorragía vítrea. Conclusión: La hemorragia vítrea es una rara complicación de hamartoma astrocítico retiniano y dificulta la exploración fundoscópica. Debería descartarse afectación sistémica


Introduction: Retinal astrocytic hamartoma is generally an asymptomatic benign tumour that may or may not be associated with the tuberous sclerosis complex. Haemorrhage is a rare presentation. Case report: The case concerns a 12-year-old patient with "a black spot" vision in the upper temporal hemifield of the right eye, who referred a similar episode 2 years ago. The anterior pole was normal in the slit lamp. A mass of translucent white-yellow peri-papillary appearance and vitreous peri-papillary haemorrhage was observed in funduscopy. The autofluorescence, fluorescence angiography, and optical coherence tomography characteristics were all compatible with retinal astrocytic hamartoma. Complementary studies (serology and X-rays) and the complete clinical examination rule out associated systemic involvement. The patient was followed-up closely until the vitreous haemorrhage was reabsorbed. Conclusion: Vitreous haemorrhage is a rare complication of Retinal astrocytic hamartoma and funduscopic exploration is difficult. Systemic involvement should be ruled out

RESUMO

OBJETIVO: Evaluar parámetros morfológicos maculares determinados mediante tomografía de coherencia óptica de dominio espectral (SD-OCT) como factores predictivos de la respuesta funcional en pacientes con degeneración macular asociada a la edad (DMAE) de tipo exudativo tratados con ranibizumab. MÉTODOS: Estudio retrospectivo de 47 pacientes diagnosticados de DMAE exudativa y tratados con ranibizumab intravítreo durante 12 meses. Mediante SD-OCT se evaluaron el grosor retiniano central (CRT), la extensión y el grosor de las alteraciones secundarias al proceso neovascular, y el estado de las bandas correspondientes a la membrana limitante externa (MLE) y a la región elipsoide de los fotorreceptores (ISe), analizándose por métodos estadísticos la relación entre estas variables y la agudeza visual. RESULTADOS: Al diagnóstico, la conservación de las bandas MLE e ISe y el CRT se correlaciona con la visión inicial. Doce meses después, el CRT y la visión final son parámetros independientes. Los análisis bivariante mostraron correlación entre la agudeza visual final y los siguientes parámetros: CRT inicial, estado inicial de las bandas ISe y MLE, y estado de estas tras la dosis de carga. El análisis de regresión lineal múltiple indica que la visión inicial y el estado de la banda ISe tras la fase de carga tienen valor predictivo de la visión final. CONCLUSIONES: El estado de conservación de las bandas ISe y MLE tras 12 meses de tratamiento con ranibizumab se correlaciona con el resultado visual. La agudeza visual inicial y el estado de la banda ISe tras la fase de carga son factores pronóstico de la agudeza visual final


OBJECTIVE: To evaluate macular morphological parameters measured by spectral domain optical coherence tomography (SD-OCT) as predictive factors of visual outcome in patients with exudative age-related macular degeneration (AMD) treated with ranibizumab. METHODS: A retrospective study was conducted on 47 patients diagnosed with exudative AMD and treated with intravitreal ranibizumab for twelve months. Central retinal thickness (CRT), extension and thickness of modifications secondary to neovascular process, and status of the bands corresponding to the external limiting membrane (ELM) and to the ellipsoid region of the photoreceptors (ISe) were evaluated by means of SD-OCT. The relationship between these variables and visual acuity was analyzed by statistical methods. RESULTS: At the time of the diagnosis, preservation of ELM and ISe bands, and CRT were correlated with initial visual acuity. Twelve months later, CRT and visual acuity were independent parameters. Bivariate relationship analysis showed a correlation between final visual acuity and the following parameters: initial CRT, initial ISe and ELM status, and ISe and ELM integrity after loading dose. Multiple regression analysis indicated that initial visual acuity and ISe band status after loading dose have a predictive value for final visual acuity. CONCLUSIONS: The status of ISe and ELM bands after twelve months of treatment with ranibizumab was associated with visual outcome. Initial visual acuity and status of the ISe band after loading dose are prognostic factors of final visual acuity
