Optical coherence tomography angiography in pituitary tumor

A 32-year-old man with a pituitary tumor had bitemporal hemianopia (figure 1). Peripapillary retinal nerve fiber layer (RNFL) in optical coherence tomography (OCT) was reduced, which corresponded to visual field defects. OCT angiography showed a dropout of capillaries and correlated well with RNFL loss in the OCT (figure 2). Compressive optic neuropathy may be associated with loss of the retinal ganglion cell layer and impaired peripapillary retinal perfusion. OCT angiography may be helpful to detect various optic neuropathies and in analyzing the vascular status of the optic nerve head and RNFL.1
