Abstract
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.
