Análisis coste-utilidad del modelo de unidad de terapia intravítrea (UTI) frente a la administración tradicional de terapia intravítrea / Cost-utility model of new intravítreous units vs. current patient journey model in Spain

Objetivo Comparar la efectividad y los costes de la implantación del Modelo de Unidad de Terapia Intravítrea (UTI), avalado por la Sociedad Española de Retina y Vítreo (SERV), Sociedad Española de Calidad Asistencial (SECA), Sociedad Española de Oftalmología (SEO) y Sociedad Española de Directivos Sanitarios (SEDISA) vs. el procedimiento habitual. Método Modelo de decisión analítico que compara una organización asistencial tipo UTI con cuatro escenarios de práctica habitual en España, en cuanto al resultado en la calidad de vida por pérdida de agudeza visual y la utilización de recursos. Se estimó la probabilidad, el coste y los años de vida ajustados por calidad (AVAC) para cada escenario planteado. Se realizó un análisis de sensibilidad univariante para cada uno de los parámetros empleados. Resultado Se observó que la implantación del modelo UTI mejora la calidad de vida de los pacientes y presenta un menor coste frente a la práctica habitual. Se produjo ahorro de costes y ganancia de AVAC. El análisis de sensibilidad mostró que el resultado no cambiaría de signo con la modificación de ninguna variable de partida. Conclusiones En las patologías oculares con indicación de tratamiento intravítreo, cualquier reducción en el tiempo que transcurre desde la sospecha diagnóstica hasta la primera inyección intravítrea disminuye la pérdida de agudeza visual. Así, actuar para acortar los tiempos sospecha-aguja es clave para mantener la visión funcional de los pacientes. La mejora de la eficiencia de los servicios de oftalmología que se organizan siguiendo el modelo UTI puede generar ahorros que varían entre los 175 € y 85 € por paciente atendido y año (AU)

Aim To compare the effectiveness and costs of the implementation of the intravitreal therapy unit model, endorsed by the SERV, SECA, SEO and SEDISA, compared to the usual procedure. Method Analytical decision model that compares an UTI-type healthcare organization with four usual practice scenarios in Spain, in terms of quality-of-life results due to loss of visual acuity and the use of resources. The probability, cost, and quality-adjusted life years (QALYs) were estimated for each scenario proposed. A univariate sensitivity analysis was performed for each of the parameters used in the model. Result The model showed that from any of the initial scenarios of the usual practice, transitioning to the UTI-type implementation improves the quality of life of patients and requires lower cost. UTI-type is dominant respect usual practice. The sensitivity analysis showed that the results would not change sign with the variation of any starting variable. Conclusions Shorten suspicion-needle times is key to maintaining functional vision in patients requiring intravitreal treatment. The UTI-type model seeks the efficiency of ophthalmology services and can produce savings that vary between €175 and €85 per patient attended per year (AU)

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)

La AVMC mejoró de 64±14 a 69±11 letras después de la terapia anti-VEGF (p>0,05). La altura media inicial del DEP fue de 817±269μm, siendo 639±268μm después de Ozurdex y 370±260μm después de las inyecciones de anti-VEGF (p=0,035 y p=0,009). Se produjo un desgarro del epitelio pigmentario de la retina (7%). No se hallaron otros efectos adversos. Conclusione El implante de dexametasona antes de la terapia anti-VEGF puede representar una modalidad terapéutica prometedora para los DEP grandes en la DMAEn, reduciendo las dimensiones del DEP y el riesgo de desgarros del epitelio pigmentario antes de la terapia anti-VEGF (AU)

Objective Evaluate the incidence of pigment epithelial tear when intravitreal delayed-release dexamethasone implant is administered (off-label use) prior to antiangiogenic treatment in pigment epithelium detachments (PED) secondary to neovascular age-related macular degeneration (nAMD) with high-risk rupture characteristics and investigate if it causes a decrease in the PED size. Methods Patients with nAMD, PED height >500microns and Ozurdex implant prior to the antiangiogenic therapy were included. The presence of pigment epithelium rupture in optical coherence tomography scans, best-corrected visual acuity (BCVA) and PED measurements (maximum height and diameter) were registered. Results The study included 14 eyes of 14 patients: mean age 77±7 years, 11 (79%) females. 25±13 days after the Ozurdex, patients started with at least 3 anti-VEGF monthly injections. BCVA improved from 64±14 to 69±11 letters after anti-VEGF therapy (P>.05). Mean baseline PED height was 817±269μm, being 639±268μm after Ozurdex and 370±260μm after anti-VEGF injections (P=.035 and P=.009). One retinal pigment epithelium tear occurred (7%). No other adverse effects were reported. Conclusions Dexamethasone implant prior to anti-VEGF therapy may represent a promising therapeutic modality for large PED in nAMD, reducing PED dimensions and the risk of pigment epithelium tears prior to anti VEGF therapy (AU)

Update on the utility of en face optical coherence tomography in the assessment of vitreoretinal diseases.

En face optical coherence tomography (EF-OCT) is a rapid, non-invasive, high-resolution imaging technique that has evolved in recent years to be a routine examination for the assessment and follow-up of various vitreoretinal diseases. With the introduction of swept-source OCT (SS-OCT), which can achieve up to 100,000 A-scans per second and better-quality imaging of deeper structures using a longer wavelength (1050nm), EF-OCT reconstruction can produce high-resolution frontal images of the retina and choroid (C-Scans) that give an overview of disease extent. These images allow a more accurate study of vitreoretinal interface pathologies such as epiretinal membranes, macular holes, and vitreomacular traction. They also provide key information in the study of various retinal vascular diseases and the differential diagnosis of cystic macular edema. EF-OCT provides valuable information about the severity of vitreoretinal interface alterations and precisely assesses the choriocapillaris and choroidal vasculature in pachychoroid disorders. Finally, this technique provides valuable information about atrophic and neovascular age-related macular degeneration and various uveitic entities. This review aims to describe the current clinical applications of EF-OCT in various vitreoretinal diseases as well as the latest findings and future perspectives.

OBJECTIVE: Evaluate the incidence of pigment epithelial tear when intravitreal delayed-release dexamethasone implant is administered (off-label use) prior to antiangiogenic treatment in pigment epithelium detachments (PED) secondary to neovascular age-related macular degeneration (nAMD) with high-risk rupture characteristics and investigate if it causes a decrease in the PED size. METHODS: Patients with nAMD, PED height >500 microns and Ozurdex implant prior to the antiangiogenic therapy were included. The presence of pigment epithelium rupture in optical coherence tomography scans, best-corrected visual acuity (BCVA) and PED measurements (maximum height and diameter) were registered. RESULTS: The study included 14 eyes of 14 patients: mean age 77 ±â€¯7 years, 11 (79%) females. 25 ±â€¯13 days after the Ozurdex, patients started with at least 3 anti-VEGF monthly injections. BCVA improved from 64 ±â€¯14-69 ±â€¯11 letters after anti-VEGF therapy (p > 0.05). Mean baseline PED height was 817 ±â€¯269 µm, being 639 ±â€¯268 µm after Ozurdex and 370 ±â€¯260 µm after anti-VEGF injections (p = 0.035 and p = 0.009). One retinal pigment epithelium tear occurred (7%). No other adverse effects were reported. CONCLUSIONS: Dexamethasone implant prior to anti-VEGF therapy may represent a promising therapeutic modality for large PED in nAMD, reducing PED dimensions and the risk of pigment epithelium tears prior to anti VEGF therapy.

Assessment of the perception of healthcare barriers and the impact of intravitreal injections on neovascular age-related macular degeneration.

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.

Assessment of vision-related quality of life and depression and anxiety rates in patients with neovascular age-related macular degeneration.

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.

Actualización en el tratamiento de la coriorretinopatía serosa central crónica / Update on the management of chronic central serous chorioretinopathy

La coriorretinopatía serosa central (CSC) es una de las principales causas de disminución de la agudeza visual en pacientes menores de 60 años. Su fisiopatología sigue siendo parcialmente desconocida, aunque se ha postulado una hiperpermeabilidad coroidea que produce típicamente un desprendimiento neurosensorial y/o un desprendimiento del epitelio pigmentario de la retina en el polo posterior. La CSC aguda generalmente no requiere tratamiento, mientras que cuando es crónica debe ser tratada para evitar un deterioro visual. Con el desarrollo de las nuevas técnicas de imagen ha existido una mejora en el diagnóstico y se han propuesto diferentes estrategias terapéuticas. Actualmente diversos tratamientos para el manejo de la CSC crónica han demostrado ser útiles para mejorar o estabilizar la agudeza visual, la resolución del fluido subretiniano y para prevenir recurrencias. Los tratamientos más empleados en la actualidad son la terapia fotodinámica con verteporfina, el láser subumbral de micropulso, el tratamiento con antagonistas de los mineralocorticoides o los fármacos intravítreos antiangiogénicos. Pero existen otras propuestas y, además, se están desarrollando nuevos tratamientos con resultados prometedores. Esta revisión pretende ofrecer al lector una visión global de la evidencia científica actual de las diferentes opciones de tratamientos disponibles para la CSC para ayudar en la toma de decisiones en la práctica clínica (AU)

Central serous chorioretinopathy (CSC) is one of the main causes of impaired visual acuity in patients younger than 60 years. Its pathophysiology remains partially unknown, although it has been postulated that choroidal hyper-permeability may be involved. This typically produces a neurosensory retinal detachment and/or a detachment of the retinal pigment epithelium in the posterior pole. Although acute CSC generally does not require treatment, when chronic it must be treated to avoid visual impairment. With the development of new imaging techniques, there has been an improvement in diagnosis, and different therapeutic strategies have been proposed. Various treatments for the management of chronic CSC have currently been shown to be useful to improve or stabilise visual acuity, the resolution of subretinal fluid, and to prevent recurrences. The most commonly used treatments today are photodynamic therapy, micropulse subthreshold laser, mineralocorticoid antagonists, or anti-vascular endothelial growth factor drugs. There are also other proposals and new treatments being developed, with promising results. This review aims to provide the reader with an overview of the current scientific evidence of the different treatment options available for CSC in order to help decision-making in clinical practice (AU)
