    A 71-year-old man presented to the clinic with complaints of a red left eye. He was sent for imaging before seeing the physician, and this fundus autofluorescence image of his left eye was taken using ultra-widefield (UWF) fundus photography (Optos). UWF imaging is used to document and evaluate the posterior segment of the eye. However, UWF fundus imaging may also reveal anterior segment findings, which artifactually appear to be on the surface of the retina and inverted. Slit-lamp examination of the patient’s left eye confirmed the presence of a corneal herpetic dendrite. This case demonstrates that UWF fundus photography could be a useful tool for documenting potentially sight-threatening anterior segment pathology when a slit lamp is not available.
