Infrared confocal scanning laser photography of a patient with long-standing optic tract lesion revealed a homonymous hemianopic hyporeflective image contralateral to the visual field defect. Spectral domain optical coherence tomography showed thinning of the retinal nerve fiber and retinal ganglion cell layer and thickening of the inner nuclear layer (with microcystic degeneration) in the macular area, matching the infrared image. Hyporeflective image on infrared laser photography is associated with retinal degeneration secondary to anterior visual pathway disease and, when located in homonymous hemianopic retinas, may represent a new sign of an optic tract lesion.
