Objective To analyse macular choroidal thickness (MCT) in non-arteritic ischaemic optic neuropathy (NAION). Materials and methods An analysis was made on 22 patients diagnosed with NAION (22 eyes) and 42 healthy controls (42 eyes) using enhanced-depth imaging of spectral-domain optical coherence tomography. A horizontal raster scan centred on the fovea was obtained per eye 3 months after the onset of NAION. Three measurements of MCT were obtained from the posterior edge of the retinal pigment epithelium to the choroid-sclera junction at 500 μm intervals. Statistical analysis was used to compare the mean MCT and to correlate MCT with other ocular and systemic parameters. Results Except for refractive error (P=.01), there were no statistically significant differences between both groups in axial length (P=.53), age (P=.88) and other epidemiological and ocular parameters. Mean MCT in NAION eyes and control group was 236.21 ± 63.29 μm and 269.13 ± 52.28, respectively. Mean MCT was significantly thinner in NAION eyes than in healthy eyes (P=.03). Thinner MCT, adjusted for refractive error, was associated with the diagnosis of NAION (P=.04). Conclusions Eyes affected by NAION showed significantly thinner MCT compared with healthy control eyes after adjusting for refractive error.
