Edad retiniana como biomarcador predictivo del grado de retinopatía diabética / Retinal age as a predictive biomarker of the diabetic retinopathy grade

Objetivo Aplicar técnicas de inteligencia artificial, mediante algoritmos de aprendizaje profundo, para el desarrollo y optimización de un sistema de predicción de la edad de una persona con base en una retinografía color, y estudiar una posible relación entre la evolución de la retinopatía diabética (RD) y un envejecimiento prematuro de la retina. Métodos Se entrenó una red convolucional para calcular la edad de una persona con base en una retinografía. Dicho entrenamiento fue realizado sobre un conjunto de retinografías de pacientes con diabetes previamente dividido en 3 subconjuntos (entrenamiento, validación y test). La diferencia entre la edad cronológica del paciente y la edad biológica de la retina se definió como gap de edad retiniano. Resultados Se utilizó un conjunto de 98.400 imágenes para la fase de entrenamiento, 1.000 imágenes para la fase de validación y 13.544 para la fase de test. El gap retiniano de los pacientes sin RD fue de 0,609 años y el de los pacientes con RD de 1,905 años (p<0,001), siendo la distribución por grado de RD de: RD leve 1,541 años; RD moderada 3,017 años; RD severa 3,117 años, y RD proliferativa 8,583 años. Conclusiones El gap de edad retiniano muestra una diferencia en positivo de media entre las personas diabéticas con RD frente a las que no tienen RD, y además aumenta progresivamente, de acuerdo con el grado de RD. Estos resultados podrían indicar la existencia de una relación entre la evolución de la enfermedad y un envejecimiento prematuro de la retina (AU)

Objective To apply artificial intelligence techniques, through deep learning algorithms, for the development and optimization of a system for predicting the age of a person based on a color retinography, and to study a possible relationship between the evolution of retinopathy diabetes (RD) and premature aging of the retina. Methods A convolutional network was trained to calculate the age of a person based on a retinography. Said training was carried out on a set of retinographies of patients with diabetes previously divided into 3 subsets (training, validation and test). The difference between the chronological age of the patient and the biological age of the retina was defined as the retinal age gap. Results A set of 98,400 images was used for the training phase, 1000 images for the validation phase and 13,544 for the test phase. The retinal gap of the patients without RD was 0.609 years and that of the patients with RD was 1905 years (p<0.001), with the distribution by degree of RD being: mild RD 1541 years; moderate RD 3017 years; RD severe 3117 years, and proliferative RD 8583 years. Conclusions The retinal age gap shows a positive mean difference between diabetics with RD versus those without RD, and it increases progressively, according to the degree of RD. These results could indicate the existence of a relationship between the evolution of the disease and premature aging of the retina (AU)

Valores de normalidad de sensibilidad retiniana y fijación foveal mediante microperimetría fotópica y escotópica en población sana / Fotopic and scotopic retinal sensitivity and foveal fixation normal values using microperimetry in healthy population

Objetivo Analizar los valores de sensibilidad retiniana y fijación foveal, en población sana, en condiciones fotópicas y escotópicas usando el microperímetro MP3-S (Nidek, Gamagori, Japón). Métodos Estudio observacional, transversal, unicéntrico. Se realizó una microperimetría (MP) fotópica y escotópica con una rejilla de estímulos personalizada de 13 puntos centrada en fóvea de 4,5×4,5mm en voluntarios sanos, sin enfermedad ocular. Se utilizó el ICC para evaluar la fiabilidad de la MP fotópica y escotópica. Resultados Se evaluaron 102 ojos de 54 voluntarios sanos (edad media: 49,8±15 años). La sensibilidad retiniana media (SRM) en la prueba fotópica y escotópica fue de 28,87±3,3 y 15,72±1,9dB, respectivamente. No se hallaron diferencias al comparar la SRM por grupo de sexos. Sin embargo, al analizar la SRM por grupos de edad se encontraron diferencias estadísticamente significativas en ambas modalidades de la prueba, siendo mayor la SRM en el grupo de sujetos menores de 35 años, con 30,3±1,7dB en la fotópica y 16,3±1,3dB en la escotópica, y menor en el grupo de mayores de 65 años, con 26,7±2,2dB en la fotópica y 13,8±1,8dB en la escotópica, con p=0,0001. En el análisis de fiabilidad, el coeficiente alfa de Cronbach reveló una excelente fiabilidad de la MP fotópica (0,958) y una buena fiabilidad de la MP escotópica (0,841). Conclusión La MP es un test con buena fiabilidad tanto en condiciones fotópicas como escotópicas. La SRM en condiciones fotópicas y escotópicas no difiere según el sexo, pero sí disminuye con la edad. Existe una correlación positiva entre la SRM fotópica y la escotópica (AU)

Purpose To determine normal values of fotopic and scotopic retinal sensitivity and foveal fixation obtained by microperimetry, using MP3-S microperimeter (Nidek, Gamagori, Japan), in a healthy population. Methods Observational, cros-sectional, single centre study. Fotopic and scotopic microperimetry (MP) was performed using with a customized 13-point fovea-centered pattern in healthy volunteers without ocular pathology. A intraclass correlation coefficient was performed to evaluate fotopic and scotopic MP reliability. Results We analyzed 102 eyes of 54 healthy volunteers (mean age 49.8±15 years old). The fotopic and scotopic mean retinal sensitivity (MRS) was 28.87±3.3dB and 15.72±1.9dB (95% CI 15.35-16.09), respectively, showing a significant statistical difference (P<.05). No differences were found when comparing MRS by gender group. However, when analyzing the MRS by age groups, statistically significant differences were found in both modalities of the test, MRS being higher in the group of subjects under 35 years of age, with 30.3±1.7dB in the photopic and 16.3±1.3dB in the scotopic, and lower in the group of older than 65 years, with 26.7±2.2dB in the photopic and 13.8±1.8dB in the scotopic, with P=.0001. The reliability analysis of both tests revealed an excellent reliability of the fotopic MP with a Cronbach alpha of 0.958 and a good reliability of 0.841 in scotopic MP. Conclusion MP is a test with good reliability both under photopic and scotopic conditons. MRS and fixation stability under photopic and scotopic conditions do not differ according to sex, but it does decrease with age. There is a positive correlation between photopic and scotopic MRS (AU)

Afectación cardiovascular en pacientes con edema macular diabético tratados con ranibizumab intravítreo en la práctica clínica habitual / Cardiovascular involvement in patients with diabetic macular oedema treated with intravitreal ranibizumab in routine clinical practice

Objetivo: Analizar la afectación cardiovascular a corto plazo de los pacientes naïve con edema macular diabético, tratados con ranibizumab intravítreo, tanto pre- como postratamiento. Material y métodos: Estudio retrospectivo y descriptivo de pacientes con edema macular diabético con afectación central, que hubieran iniciado tratamiento con ranibizumab intravítreo en 2014 en el Hospital Universitario Nuestra Señora de Candelaria y el Hospital Universitario y Politécnico La Fe. Se siguieron hasta agosto de 2015, estudiando, entre otras variables, la prevalencia e incidencia de accidente cerebrovascular y de infarto agudo de miocardio. Resultados: De las 1.324 inyecciones de ranibizumab intravítreo que se administraron en 2014, solo 159 fueron como inicio de tratamiento, repartidas entre un total de 99 pacientes, ya que más de la mitad de ellos precisó tratamiento de ambos ojos (58,6%). El 58,4% de los pacientes fueron hombres, en la sexta década de la vida (X¯=65,93 años ± 11,24) y, en su mayoría, no fumadores (86,7%), diabéticos tipo 2 (91,9%), hipertensos (70,7%) y dislipidémicos (65,7%). Se encontraron 6 pacientes (6,1%) con infarto agudo de miocardio y 8 (8,1%) con accidentes cerebrovasculares (ACV) previos al inicio del tratamiento, y solo uno (1%) con accidente cerebrovascular posterior (p = 0,039). Conclusión: En nuestra experiencia el ranibizumab intravítreo en pacientes con edema macular diabético, con antecedentes de accidente cerebrovascular e infarto agudo de miocardio podría ser una alternativa segura (AU

Objective: To determine the cardiovascular events in naïve patients with diabetic macular oedema, before and after being treated with intravitreal ranibizumab. Material and methods: A retrospective and descriptive study was conducted on patients with diabetic macular oedema and foveal involvement, who started treatment with intravitreal ranibizumab in 2014 in the Hospital Universitario Nuestra Señora de Candelaria and the Hospital Universitario y Politécnico La Fe. During the follow-up until August 2015, a record was made of parameters, including the prevalence and incidence of stroke and myocardial infarction. Results: Among the 1,324 intravitreal ranibizumab injections administered in 2014, only 159 of them corresponded to treatment initiation in 99 patients, with more than half requiring treatment of both eyes. The study patients included 58.4% males, in the 6th decade of life (Mean = 65.93 ± 11.24 years), non-smokers (86.7%), type 2 diabetes (91.9%), hypertension (70.7%), and with dyslipidaemia (65.7%). Prior to treatment initiation, it was found that 6 patients (6.1%) suffered from an acute myocardial infarction, and 8 (8.1%) from stroke, and only one (1%) with post-stroke (P = .039). Conclusion: In our experience it seems that the intravitreal ranibizumab in diabetic macular oedema could be a safe alternative in patients with a history of stroke and myocardial infarction (AU)
