Nepafenac for cystoid macular oedema secondary to paclitaxel.

Paclitaxel is used to treat a wide range of malignant tumours. This type of drug is known to cause ocular adverse effects, with cystoid macular oedema being a known, but rare complication, of this therapy. Although most cases resolve after discontinuation of the drug, several authors have attempted various treatments to accelerate resolution, or when paclitaxel therapy cannot be discontinued. A case is presented of a 62 year-old man who presented with decreased visual acuity due to bilateral cystoid macular oedema after administration of paclitaxel for oesophageal cancer. As part of the study, optical coherence tomography angiography (OCTA) was performed at the time of diagnosis, and later when the symptoms subsided. Nepafenac eye drops were prescribed as treatment.

Nepafenaco para edema macular cistoideo secundario a paclitaxel / Nepafenac for cystoid macular oedema secondary to paclitaxel

El paclitaxel es utilizado para tratar una amplia gama de tumores malignos. Se sabe que estos fármacos causan efectos adversos oculares, siendo el edema macular cistoide una complicación conocida pero rara de esta terapia. Aunque la mayoría de los casos se resuelven después de la interrupción del fármaco, varios autores han intentado diversos tratamientos para acelerar la resolución o cuando la terapia con paclitaxel no puede suspenderse. Presentamos un caso de un varón de 62 años que presentó disminución de la agudeza visual debido a edema macular cistoideo bilateral después de la administración de paclitaxel para cáncer de esófago; como parte del estudio se realizó angiografía por tomografía de coherencia óptica en el momento del diagnóstico y posteriormente cuando el cuadro remitió. Como tratamiento se prescribió colirio de nepafenaco (AU)

Retinopatía MEK. Casos clínicos / MEK Retinopathy. Clinical case reports

CASOS CLÍNICOS: Se presentan 3 casos clínicos de retinopatía MEK asociados al uso de la combinación de cobimetinib y vemurafenib, caracterizados por la alteración del epitelio pigmentario de la retina y desprendimiento neurosensorial. Dos de ellos conservaron la visión de la unidad, el tercero desarrolló un gran desprendimiento neurosensorial bilateral con una agudeza visual final de 0,6 en el ojo derecho y de 0,1 en el izquierdo. DISCUSIÓN: Las nuevas estrategias terapéuticas frente al melanoma cutáneo metastásico condicionan la aparición de alteraciones del epitelio pigmentario de la retina con desprendimientos serosos, lo que obliga a una vigilancia estrecha bajo tomografía de coherencia óptica macular

CASE REPORTS: Three clinical cases are presented of MEK retinopathy associated with the combination of cobimetinib and vemurafenib characterised by alteration of the retinal pigment epithelium and neurosensory detachment. Two of the cases conserved the vision of the unit, and the third developed a large bilateral neurosensory detachment with final visual acuity of 0.6 for the right eye and 0.1 for the left one. DISCUSSION: The new therapeutic strategies against metastatic cutaneous melanoma condition the appearance of alterations of the pigmentary epithelium of the retina with serous detachments, leading to close monitoring with macular optical coherence tomography

Resultados coste-efectividad del implante de dexametasona en edema macular / A cost-effectiveness study of dexamethasone implants in macular edema

OBJETIVO: Analizar el beneficio coste-efectividad del implante intravítreo de dexametasona (Ozurdex®, Allergan, Irvine, CA, EE. UU.) en sus aplicaciones clínicamente relevantes. MATERIAL Y MÉTODOS: Un total de 88 ojos de 86 pacientes con edema macular de > 300 μm medido mediante tomografía de coherencia óptica (Zeiss Cirrus, Dublín, CA, EE. UU.) fueron incluidos en este trabajo retrospectivo de 2 años, con un seguimiento mínimo de 6 meses. Se incluyeron 3 grupos de pacientes: el grupo 1 con edema macular en oclusión venosa retiniana, el grupo 2 con uveítis posterior no infecciosa y el grupo 3 con edema macular diabético, estando este fuera de indicación pero avalado por la literatura médica. Antes del implante y los días 1, 30, 60, 90 y 180 se evaluó la agudeza visual corregida (Snellen), espesor retiniano central, presión intraocular y biomicroscopia. Los análisis de coste-beneficio se tabularon por línea de visión ganada, comparando las principales alternativas terapéuticas, y se valoró el perfil de seguridad del implante intravítreo de dexametasona (Ozurdex®; Allergan, Irvine, CA, EE. UU.). RESULTADOS: Los resultados de este estudio no difirieron de los publicados por otros, en términos de mejoría de la agudeza visual en el 63,3% y del espesor macular central en el 97%. En los casos de recidiva, se produjo a los 120 días de media; la necesidad de retratamiento fue del 40,9%. Entre los efectos secundarios, el incremento de presión intraocular > 23 mm Hg se produjo en el 29,54%, controlándose con tratamiento tópico, excepto un 1,13% de los casos que requirieron tratamiento quirúrgico. El desarrollo de catarata fue del 44,7%, requiriendo cirugía un 10,6%. Los resultados del tratamiento mostraron una menor necesidad en la frecuencia del uso de Ozurdex® frente a otros tratamientos para el control de la enfermedad, convirtiéndose en una opción que permite el ahorro de costes. DISCUSIÓN: Los análisis coste-efectividad son clínicamente relevantes cuando se aplican estrategias terapéuticas en pacientes con edema macular. El implante de dexametasona intravítrea es una opción terapéutica segura y eficiente

OBJECTIVE: To analyze the cost-effectiveness and benefits of a dexamethasone intravitreal implant (Ozurdex®, Allergan, Irvine, CA, USA.) in its clinically relevant applications. MATERIAL AND METHODS: A total of 88 eyes of 86 patients with macular edema of > 300 μm measured by optical coherence tomography (Cirrus Zeiss, Dublin, CA, USA) were included in this two-year retrospective study, with a minimum of 6 months follow-up. The patients were divide into 3 groups: group 1 with macular edema in retinal vein occlusion, group 2 with non-infectious posterior uveitis, and group 3 with diabetic macular edema. The treatment was off-label but supported by the literature. Before implantation, and on days 1, 30, 60, 90 and 180, corrected visual acuity (Snellen), central retinal thickness, intraocular pressure and biomicroscopy were evaluated. The cost-benefit analysis was tabulated by line of visual acuity gained, comparing the main therapeutic alternatives and assessment of the safety profile of the dexamethasone intravitreal implant (Ozurdex®, Allergan, Irvine, CA, USA). RESULTS: The results of this study did not differ from the published studies, in terms of visual acuity improvement in 63.3% of cases, and with central macular thickness improvement in 97% of cases. There were relapses, which occurred after 120 days on average, and the need for retreatment was 40.9%. Increased intraocular pressure >23 mm Hg was among the side effects in 29.54%, and was controlled with topical treatment, except in 1.13% requiring surgical treatment. The development of cataract was 44.7%, and 10.6% required surgery. Treatment results showed less frequent use of Ozurdex® than other treatments for disease control, being a cost saving option. DISCUSSION: Cost-effectiveness analyses are clinically relevant when applying treatment strategies in patients with macular edema. Dexamethasone intravitreal implant appears to be a safe and efficient therapy

Diabetic retinopathy and macular oedema]. / Guías de práctica clínica de la SERV: manejo de las complicaciones oculares de la diabetes. Retinopatía diabética y edema macular.

OBJECTIVE: Diabetes mellitus is considered the most common cause of blindness in the working population of industrialized countries, with diabetic macular edema being the most common cause of decreased visual acuity and proliferative diabetic retinopathy (PDR) being responsible for the most severe visual deficits. We have therefore tried to establish a guide for clinical intervention whose purpose is to provide orientation on the treatment of diabetic retinopathy and its complications. This is necessary at a time when many treatment options have emerged whose role is not yet fully defined. METHOD: A group of expert retina specialists selected by the SERV (Vitreous-Retina Spanish Society) assessed the published results of different treatment options currently available, suggesting lines of action according to the degree of diabetic retinopathy present and the presence or absence of macular edema. RESULTS: PDR is primarily treated with pan-retinal photocoagulation. For clinically significant diabetic macular edema without signs of vitreomacular traction, the treatment of choice continues to be focal/grid photocoagulation. Similarly, retinovitreal surgery is indicated for both conditions. The use of antiangiogenic drugs was also analyzed but remains inconclusive. CONCLUSION: Laser therapy is effective in the management of diabetic retinopathy and diabetic macular edema. The role of antiangiogenics is not yet sufficiently defined.

[Review of the protocol for the treatment of diabetic retinopathy]. / Revisión del protocolo para el tratamiento de la retinopatía diabética.

We present general guidelines to help us with the treatment of diabetic retinopathy (DR) at a time when numerous therapeutic alternatives have been developed although their role has not yet been adequately defined. This protocol is not directed at experienced retinologists but rather at general ophthalmologists who require a practical and up to date guide of a pathology as prevalent as RD. The different therapeutic options available, and their most accepted indications depending on the degree of diabetic retinopathy that patients have, are reviewed. We propose what to do in cases of mild, moderate and severe non-proliferative diabetic retinopathy as well as in cases of proliferative diabetic retinopathy (panphotocoagulation/antiangiogenic drugs/vitreorretinal surgery). The treatment of diabetic macular edema depending on its angiographic and topographic characteristics is also discussed. The importance of metabolic control of the patient is stressed (tight glycemic control, control of arterial hypertension and dyslipemia) in aiding the treatment of diabetic retinopathy. This therapeutic proposal has been discussed widely by retinologists from the four largest hospitals in the Canary Islands, and is therefore an agreed text based on recent scientific literature.
