ABSTRACT
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.

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)

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 2â¯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.

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)

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.

La telangiectasia macular idiopática tipo 1 (MacTel 1) se presenta casi siempre de forma unilateral. En este artículo publicamos el caso de un varón de 73 años, sin antecedentes de importancia, diagnosticado de MacTel 1, pero de presentación atípica bilateral, algo muy infrecuente en esta enfermedad. Se resalta la utilidad de estudio con imagen multimodal, incluyendo la angiografía por tomografía de coherencia óptica (OCTA) para diferenciarla de la telangiectasia macular tipo 2 (MacTel 2). El cuadro del paciente se caracterizó por edema macular cistoideo (EMC), con discreta respuesta al tratamiento con implante de dexametasona. Sin embargo, la terapia con aflibercept mostró resultados favorables, pero con recurrencias al extender las dosis (AU)

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.

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)

ABSTRACT
We present a case of a woman with idiopathic macular telangiectasia type 1, characterized by the presence of a capillary macroanaeurysm associated with macular edema with a macular star pattern. Several differential diagnoses were proposed, in which the study with a multimodal image was key to clarify the diagnosis. In addition, the various treatments used and their effectiveness are discussed.

ABSTRACT
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.
