Optical Coherence Tomography Angiography in a Patient with Optic Atrophy After Non-arteritic Anterior Ischaemic Optic Neuropathy

ABSTRACT

A 75-year-old female noticed a lower visual field (VF) defect in the right eye. A diagnosis of non-arteritic anterior ischaemic optic neuropathy (NAION) was made. The lower VF defect in the right eye did not change after onset. Optical coherence tomography (OCT) angiograms on the disc and the macula showed decreased retinal perfusion in the upper retina of the right eye. Retinal nerve fibre layer loss and ganglion cell complex loss in the upper retina were also seen in the right eye. OCT angiography could non-invasively detect the decrease of the retinal perfusion due to NAION.
