We present the case of a 45-year-old man who came to the emergency department with a sudden decrease in vision in his left eye. As recent history, the patient had suffered an episode of influenza a few days earlier. A complete ophthalmological examination was performed, which determined a visual acuity of unity in the right eye, the examination data being compatible with normality, including the fundus. The examination of the left eye, however, showed a visual acuity of 0.800 and the fundus showed lesions in the macular and central foveolar area with a rounded orange appearance. Given the history of influenza and the patient's clinical picture, treatment with NSAIDs (ibuprofen 600 mg/12 hours) was prescribed and a FFA and EOG were requested.

The EOG showed a slight alteration in the left eye, being compatible with normality in the right eye. FFA in the right eye was compatible with normality, but in the left eye there were hyperfluorescent areas with a central hypofluorescent spot, without contrast diffusion at late times.

Complementary tests confirmed the diagnosis of suspected ARD and, given that the evolution of the disease was likely to resolve spontaneously, treatment with NSAIDs was suspended.
The patient evolved favourably, recovering unit vision in his left eye between the 3rd and 4th week after the onset of the clinical picture.
