Optical coherence tomography angiography of optic disc perfusion in non-arteritic anterior ischemic optic neuropathy

To compare the optic disc blood flow of non-arteritic ischemic optic neuropathy (NAION) eyes with normal eyes. The optic disc blood flow densities of diagnosed non-acute phase NAION eyes (21 eyes, 14 individuals) and normal eyes (19 eyes, 12 individuals) were detected Optovue optical coherence tomog...

Description
Summary:To compare the optic disc blood flow of non-arteritic ischemic optic neuropathy (NAION) eyes with normal eyes. The optic disc blood flow densities of diagnosed non-acute phase NAION eyes (21 eyes, 14 individuals) and normal eyes (19 eyes, 12 individuals) were detected Optovue optical coherence tomography angiography (OCTA). The optic disc blood flow was measured Image J software. Correlations between optic disc perfusion and visual function variables were assessed by linear regression analysis. The average percentage of the optic disc non-perfusion areas in the non-acute phase NAION patients (17.84%±6.18%) was increased, when compared to the normal control eyes (8.61%±1.65%), and the difference was statistically significant (
