Optic disc parameters and choroidal vascular index as potential risk indicators in non-arteritic anterior ischaemic optic neuropathy: a retrospective study

Puntos clave

Reductions in choroidal vascular index and OCTA parameters were seen in NAION eyes, indicating potential risks.
Choroidal parameters showed no significant correlations with OCTA metrics across different NAION groups or stages.
Retrospective analysis evaluated optic disc parameters and choroidal vascular index concerning NAION.
Findings highlight the need for monitoring disease progression using non-invasive OCTA tools in NAION cases.

Resumen

There were no significant correlations between OCTA and choroidal parameters across all groups. These findings suggest that the retina and choroid are affected through distinct mechanisms in NAION. However, reductions in OCTA parameters, including CVI, were evident in NAION eyes. Overall, the study findings underscore the potential of OCTA as a non-invasive tool for identifying risk factors and monitoring disease progression in NAION.
