ACCEPTED MANUSCRIPT Abstract Purpose:
To examine choroidal thickness in non-arteritic anterior ischemic optic neuropathy
(AION). Design:
Retrospective case control study
Methods: Setting: Eye Clinic, University Medical Center Mannheim, Germany. The study group consisted of patients with non-arteritic AION, and the
RI PT
Study Population:
control group consisted of individuals with a normal fundus. Observation:
Choroidal thickness was measured by enhanced depth imaging of
spectral-domain optical coherence tomography. Main Outcome Measure: Results:
Choroidal thickness.
The study group consisted of 20 patients: 11 patients with acute non-arteritic AION

In a second step of the statistical analysis, we searched for associations between SFCT and other parameters in the control group.
It revealed that SFCT was significantly
associated with younger age (P=0.001) and hyperopic refractive error (P=0.049), whereas

In a third step of the analysis, we performed a multivariate analysis with SFCT as independent variables.
