Glaucoma avanzado. Guía de práctica clínica / Advanced glaucoma. Clinical practice guideline

objetivo Realización de una guía de práctica clínica actualizada que sirva de orientación para la detección, el manejo y el tratamiento de pacientes con glaucoma avanzado en la edad adulta. Métodos Tras la definición de los objetivos y alcance de la guía se constituyó el grupo de trabajo que formuló las preguntas clínicas estructuradas siguiendo el formato PICO (Patient, Intervention, Comparison, Outcomes). Se realizó una revisión de la literatura publicada hasta el momento, incluyendo guías de práctica clínica internacionales, utilizándose las herramientas AMSTAR-2 (Assessment of Multiple systematic Rewiews) y «Risk of Bias» de Cochrane para la evaluación de la calidad de la información de forma independiente por, al menos, 2 revisores. El nivel de evidencia y la elaboración del grado de recomendación se establecieron siguiendo la metodología del Scottish Intercollegiate Guidelines Network (SIGN). Resultados Se presentan recomendaciones con sus correspondientes niveles de evidencia que pueden ser de utilidad para la detección, el seguimiento y el tratamiento de pacientes con glaucoma avanzado en la edad adulta. Conclusiones A pesar de que la evidencia científica existente es escasa y el nivel de evidencia para muchas de las preguntas planteadas no es muy alto, esta guía de práctica clínica ofrece una revisión actualizada de las recomendaciones existentes para el manejo del glaucoma avanzado en el adulto (AU)

Importancia de la electrofisiología ocular en el diagnóstico de las distrofias retinianas / Importance of ocular electrophysiology in the diagnosis of retinal dystrophies

Antecedentes y objetivo: El diagnóstico de las distrofias retinianas es complejo y se basa en estudio oftalmológico completo, estudio genético y los estudios electrofisiológicos (EEF). En este estudio pretendemos evaluar el papel de las pruebas electrofisiológicas y del médico solicitante en el diagnóstico de las distrofias de retina. Materiales y métodos: Estudio observacional retrospectivo. Se seleccionaron 50 pacientes atendidos en el Servicio de Neurofisiología del Hospital Universitario Virgen Macarena. Se valoró el sexo, la edad, el hospital de origen, motivo por el que se solicitó los EEF, diagnóstico de presunción tras examen oftalmológico, EEF realizados, estudio genético y el diagnóstico definitivo tras realización de EEF. Se elaboró un sistema de clasificación que otorga a cada caso un valor comprendido entre 0 y 2, en función de la contribución de las pruebas electrofisiológicas al diagnóstico final. Resultados: La edad media fue 44,34 ± 18,03 años (60% mujeres). Retinosis pigmentaria, neuropatía óptica y enfermedad de Stargardt fueron los diagnósticos más frecuentes. Los EEF modificaron el diagnóstico de presunción en el 48% de los casos, confirmaron el diagnóstico en el 44% y no aportaron información en el 8%. La contribución de los EEF fue mayor en pacientes atendidos en el Hospital Universitario Virgen Macarena y cuando se solicitaban por hallazgos en la exploración (p = 0,001). Los falsos positivos para distrofia retiniana fueron del 60% en pacientes no valorados en dicho hospital. Conclusiones: Las pruebas electrofisiológicas y el manejo especializado de los pacientes con distrofias retinianas desempeñan un papel importante en el diagnóstico de estas patologías

Background and objective; The diagnosis of retinal dystrophies is complex and is based on complete ophthalmological study, genetic study and electrophysiological studies (EPS). In this study, we intend to evaluate the role of electrophysiological and medical tests in the diagnosis of retinal dystrophies. Material and methods: A retrospective observational study was conducted on 50 selected patients that attended the Neurophysiology Department of the University Hospital Virgen Macarena. An analysis was made of the variables that included, gender, age, referral hospital, reason for which the EPS was requested, applied EPS, genetic study, presumed diagnosis, and definitive diagnosis after EPS. A classification system was subsequently developed, which gives each case a value between 0 and 2, depending on the contribution of the electrophysiological tests to the final diagnosis. Results: The mean age was 44.34 ± 18.03 years (60% women). Retinitis pigmentosa (24%), optic neuropathy (12%), and Stargardt's disease (8%) were the most frequent diagnoses. The EPS modified the presumed diagnosis in 48% of the cases, confirmed the diagnosis in 44%, and did not provide any useful information in 8%. The contribution of the EPS was greater in patients seen in the HUVM and when requested by findings in the examination (P = .001). The false positives in the diagnosis of retinal dystrophy were 60% in patients not evaluated by the University Hospital Virgen Macarena. Conclusions: Electrophysiological test and specialised management of patients with retinal dystrophies play an important role in the diagnosis of these conditions

Retinoblastoma: la importancia de su diagnóstico precoz / Retinoblastoma: The importance of early diagnosis

INTRODUCCIÓN: El retinoblastoma es el tumor intraocular maligno más frecuente en la infancia y tanto su curación como las secuelas derivadas del mismo dependen fundamentalmente de un diagnóstico precoz. En la actualidad, no existe consenso en su manejo diagnóstico y terapéutico. PACIENTES Y MÉTODOS: Estudio descriptivo, retrospectivo, no aleatorizado, de serie de casos (39 pacientes-58 ojos), tratados durante el período 2006-2013 en nuestro servicio, nombrado centro de Referencia Regional de Tumores por la Agencia de Calidad del SNS. RESULTADOS: El signo más frecuente de comienzo es la leucocoria (71,8%), seguido de estrabismo (17,9%). Todos los casos de tumoración bilateral presentaban mutación germinal del gen RB1 y un 20% tenían antecedentes familiares. El 55% de los pacientes presentaron estadio E, y el 90% precisó tratamiento quimioterápico. Un 57% de los que presentaban estadios leves, conservaron su ojo respecto al 43% que lo conservó en estadios avanzados. CONCLUSIONES: Este análisis consta de 58 ojos, sin que existan estudios previos en nuestra comunidad y pocas series tan numerosas en todo el país. Basado en tratamiento no estandarizados, eligiendo el más adecuado según las características del tumor. El manejo multidisciplinar, formado por oftalmología, oncología pediátrica, oncología radioterápica y radiofísica, es fundamental para la elección de tratamiento más correcta. La quimiorreducción junto a tratamientos de consolidación ofrece resultados esperanzadores en el control de los mismos, sobre todo en los de menor severidad. La enucleación continúa siendo de elección en las estadificaciones más avanzadas con afectación vítrea, poniendo de manifesto la importancia de su diagnóstico precoz

INTRODUCTION: Retinoblastoma is the most frequent malignant intraocular tumour in childhood, and both its cure and the sequelae arising from it, mainly depend on an early diagnosis. There is currently no consensus on its diagnostic and therapeutic management. PATIENTS AND METHODS: A descriptive, retrospective, and non-randomised study was conducted on a series of cases (39 patients -58 eyes), treated during the period 2006-2013, in the Regional Reference Centre for Tumours of the National Health Service Quality Agency. RESULTS: The most frequent presentation sign is leukocoria (71.8%), followed by strabismus (17.9%). All cases of bilateral tumour had a germline mutation of the RB1 gene, and 20% had a family history. Stage E was observed in 55% of the patients, and 90% required chemotherapy treatment. The eye was maintained in 57% of those who had mild stages, compared to 43% who maintained it in advanced stages. CONCLUSIONS: This analysis included 58 eyes. There are no previous studies in our community and there are few series so numerous throughout the country. Based on non-standardised treatment, the most appropriate is chosen according to the characteristics of the tumour. The multidisciplinary management, formed by ophthalmology, paediatric oncology, radiotherapy, and radiophysical oncology, is fundamental for the selection of the most appropriate treatment. Chemo-reduction, along with consolidation treatments, offers encouraging results in the control of these tumours, especially in those of less severity. Enucleation continues to be the method of choice in the most advanced staging with vitreous involvement, with the importance of early diagnosis being highlighted
