Central retinal artery occlusion as a post-transfusion complication of red blood cells. / Oclusión de la arteria central de la retina como complicación postransfusional de glóbulos rojos.

A 32-year-old woman presented with a history of uterine myomatosis and repeated bleeding for 6 months. This produced a haemoglobin concentration of 6.5 g/dL, with a requirement for a red blood cell transfusion. One hour after the transfusion, she presented with a sudden and painless loss of vision in the right eye (RE). As she had no other symptoms, she was referred to the Neuro-Ophthalmology Department. On admission, her corrected visual acuity was hand movement in RE, and 0.6 in the left eye (LE). The anterior segment was unremarkable, except for a relative afferent pupillary defect in RE. In the fundus examination, the RE showed a diffuse pale retina with a cherry spot, consistent with occlusion of the central artery of the retina. Management was attempted but with no improvement. The studies corroborated retinal ischaemia in RE. During the systemic evaluation, the neuroimaging, autoimmune and haematology studies were negative, thus this complication was attributed to the red blood cell transfusion.

Mujer de 32 años con antecedente de miomatosis uterina y metrorragias a repetición durante seis meses que condicionan una concentración de hemoglobina de 6,5 g/dL con requerimiento de transfusión de eritrocitos. Presentó una hora postransfusión, pérdida visual súbita e indolora del ojo derecho (OD) sin otra sintomatología, siendo remitida al departamento de Neuro-oftalmología. Al ingreso su agudeza visual corregida fue movimiento de manos en OD y 0,6 en el izquierdo (OI). El segmento anterior fue normal, salvo un defecto pupilar aferente relativo en OD. Funduscópicamente el OD resaltó una retina pálida difusa con mancha rojo cereza, compatible con oclusión de la arteria central de la retina, OI normal. Se intentó manejo sin mejoría. Los estudios oculares corroboraron isquemia retiniana en OD. Durante la evaluación sistémica los estudios de neuroimágenes, paneles autoinmunes y hematológicos fueron negativos, por lo que se atribuyó dicha complicación a la transfusión de glóbulos rojos (AU)
