Acute macular neuroretinopathy (AMN) related to energy drink consumption

This case identifies a newly found association between energy drinks and acute macular neuroretinopathy (AMN). Our patient, a 34-year-old woman with no significant ocular or previous medical history, presented with a 3-day history of decreased vision after consumption of multiple energy drinks. After near infrared and optical coherence tomography imaging, we were able to diagnose her with AMN. Our patient’s vision improved over a 2-month course with no intervention. Our case aims to emphasise the effect of caffeine on the retina, as well as encourage clinicians to consider energy drinks as a causative agent of AMN.
