Retinal Imaging of an Optic Tract Lesion: OCT Angiography of Structural and Functional Defects

A 44-year-old man presented with a 10-month history of right-sided vision loss. Humphrey visual fields showed a right, incomplete homonymous hemianopia (Fig 1A) secondary to a left optic tract metastasis from melanoma (Fig  1C). Homonymous macular ganglion cell complex loss and “bow-tie” retinal nerve fiber loss were demonstrated with OCT (Fig 1B). OCT-angiography showed dropout of capillaries in the retinal superficial vascular plexus centered on the optic discs in the areas of “bow-tie” atrophy (Fig 1D).
