Analysis of peripapillary choroidal thickness in non-arteritic anterior ischaemic optic neuropathy.

Purpose: To analyse peripapillary choroidal thickness (PCT) in non-arteritic ischaemic optic neuropathy (NAION).

Methods: 28 patients diagnosed with NAION (37 affected and 19 unaffected eyes) and 38 disease-free control individuals (38 eyes) were analysed using enhanced-depth imaging of spectral-domain optical coherence tomography. A vertical and a horizontal raster scan centred on the optic nerve were obtained per eye.
