Choroidal macrovessel and persistent metamorphopsia after epiretinal membrane surgery.

We report the case of a 59-year-old man with decreased visual acuity and metamorphopsia in both eyes in the context of bilateral epiretinal membrane (ERM) who underwent retinovitreal surgery (chromovitrectomy plus peeling of internal limiting membrane). He recovered visual acuity in his left eye. However, the visual results of his right eye were not satisfactory, with persistence of metamorphopsia in that eye. The multimodal imaging study that included color and red filter retinographies, enhanced depth imaging optical coherence tomography (EDI-OCT), fluorescein angiography (FA), indocyanine green angiography (ICGA), OCT angiography (OCTA) and OCT en face, were useful to diagnose a choroidal macrovessel. This ran from the fovea to the temporal macula. EDI-OCT revealed that the choroidal macrovessel generated a foveal deformation of both the ellipsoid zone (EZ) and the retinal pigment epithelium (RPE). This paper discusses whether structural changes in the fovea generated by the choroidal macrovessel are related to persistent metamorfopsia in the affected eye.

Macrovaso coroideo y metamorfopsia persistente después de cirugía de membrana epirretiniana / Choroidal macrovessel and persistent metamorphopsia after epiretinal membrane surgery

Presentamos el caso de un hombre de 59 años con disminución de agudeza visual y metamorfopsia en ambos ojos en el contexto de membrana epirretiniana bilateral (MER) que fue intervenido con cirugía retinovítrea (cromovitrectomía más pelado de membrana limitante interna). Presentó recuperación de agudeza visual en su ojo izquierdo. Sin embargo, los resultados visuales de su ojo derecho no fueron satisfactorios, con persistencia de metamorfopsia en dicho ojo. El estudio con imagen multimodal que incluyó retinografía en color y filtro rojo, tomografía de coherencia óptica con imagen de profundidad mejorada (OCT-EDI), angiografía fluoresceínica (AF), angiografía verde de indocianina (ICGA), OCT-angiografía (OCTA) y OCT en-face fue útil para diagnosticar un macrovaso coroideo. Este recorría desde la fóvea hasta la mácula temporal. La OCT-EDI reveló que el macrovaso coroideo generaba una deformación foveal tanto de la zona elipsoide (ZE) como del epitelio pigmentario de retina (EPR). En este trabajo se discute si los cambios estructurales en la fóvea generados por el macrovaso coroideo están relacionados con la metamorfopsia persistente en el ojo afectado (AU)

OCT-angiography for diagnosis and response to treatment of subretinal neovascularization secondary to idiopathic macular telangiectasia type 2.

Idiopathic macular telangiectasia type 2 (MacTel 2) is a slow and progressive bilateral condition that affects middle-aged and elderly individuals. Vision loss is generally mild and occurs over the course of many years. The development of sub-retinal neovascularisation (SRNV) can occur late in the disease process, and lead to more dramatic vision loss. A report is presented of 2 cases of MacTel 2 in which optical coherence tomography angiography (OCTA) was essential for the diagnosis of secondary SRNV. The commercially available OCTA Cirrus AngioPlex 5000 platform (Zeiss, Jena, Germany) was used. Subretinal neovascularization was detectable in both cases in OCTA at the level of the deep capillary plexus and the avascular layer. OCTA also allowed us to monitor disease progression and monitor response to anti-VEGF therapy.

Angiografía-OCT para diagnóstico y respuesta al tratamiento de la neovascularización subretiniana secundaria a telangiectasia macular idiopática tipo 2 / OCT-angiography for diagnosis and response to treatment of subretinal neovascularization secondary to idiopathic macular telangiectasia type 2

La telangiectasia macular idiopática tipo 2 (MacTel 2) es una afección bilateral, lenta y progresiva que afecta a individuos de mediana edad y ancianos. La pérdida de visión es generalmente leve y ocurre en el transcurso de muchos años. El desarrollo de neovascularización subretiniana (NVSR) puede ocurrir tarde en el proceso de la enfermedad y conducir a una pérdida de visión más dramática. Presentamos 2casos de MacTel 2 donde la angiografía por tomografía de coherencia óptica (OCTA) fue fundamental para el diagnóstico de NVSR secundaria. Se utilizó la plataforma comercialmente disponible OCTA Cirrus AngioPlex 5000 (Zeiss, Jena, Alemania). La NVSR fue detectable en ambos casos con OCTA a nivel del plexo capilar profundo y en la capa avascular. La OCTA también nos permitió controlar la progresión de la enfermedad y monitorizar la respuesta a la terapia anti-VEGF (AU)

Atypical bilateral presentation in idiopathic macular telangiectasia type 1.

Idiopathic macular telangiectasia type 1 (MacTel 1) almost always occurs unilaterally. In this article, we report the case of a 73-year-old man with no significant history diagnosed with MacTel 1 but with atypical bilateral presentation, something very rare in this disease. The usefulness of multimodal imaging studies, including optical coherence tomography angiography (OCTA), is highlighted to differentiate it from macular telangectasia type 2 (MacTel 2). The patient's condition was characterized by cystoid macular edema (CME) with discreet results with treatment with a dexamethasone implant. However, aflibercept therapy showed favorable results, but with recurrences when extending the doses.

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.

Secondary visual loss due to inhalation and cutaneous poisoning by methanol and toluene. Presentation of a clinical case. / Pérdida visual secundaria a intoxicación inhalatoria y cutánea por metanol y tolueno. A propósito de un caso.

Methanol poisoning is often described in the literature, but not transdermal or inhalational poisoning. It usually involves variable multi-organ damage, among which visual, neurological, and gastrointestinal involvement, as well as the metabolic and electrolyte changes that can lead to death. Contact with toluene by occupational or intentional inhalation may also cause neurological abnormalities. This article describes the case of a female patient who was seen in the Emergency Department due to bilateral visual loss secondary to accidental poisoning (inhalation-transdermal) with a solvent containing methanol and toluene. She had a favourable outcome during admission after treatment with ethanol in perfusion and corticosteroids.

Tratamiento de un caso de toxicidad retiniana por aminoglucósidos con megadosis de corticoides más implante de dexametasona intravítreo (Ozurdex®) / A case of aminoglycosides induced retinal toxicity treated with megadoses of steroids and an intravitreal dexamethasone implant (Ozurdex®)

CASO CLÍNICO: Paciente que tras cirugía de glaucoma presenta pérdida súbita de visión, llegándose al diagnóstico de toxicidad retiniana por tobramicina, caracterizada por blanqueamiento retiniano con mancha rojo cereza, edema macular, y vasculitis con evolución a atrofia papilar y macular con esclerosis arteriolar. Ante la gravedad del cuadro ensayamos con megadosis de corticoides e implante intravítreo de dexametasona (Ozurdex®, Allergan S.A.) precozmente, sin buena respuesta. DISCUSIÓN: La toxicidad por aminoglucósidos es una complicación infrecuente, muy grave e idiosincrásica. Destacar que no existe tratamiento efectivo

CASE REPORT: The case is described of a patient who had a sudden loss of vision in her right eye after glaucoma surgery. A diagnosis of retinal toxicity due to tobramycin (an aminoglycoside) was reached, which was characterised by retinal whitening with a red cherry stain, macular oedema, and vasculitis that progressed to papillary and macular atrophy with arteriolar sclerosis. Given the severity of symptoms an early attempt was made with megadoses of steroids and an intravitreal dexamethasone implant (Ozurdex®, Allergan S.A.), without response. DISCUSSION: Aminoglycoside toxicity is a rare, idiosyncratic, very serious complication for which there is no effective treatment
