title: Subfoveal choroidal thickness in patients with chronic heart failure analyzed by spectral-domain optical coherence tomography.
abstract: OBJECTIVE
  To evaluate the subfoveal choroidal thickness (SFCT) measured by enhanced depth imaging optical coherence tomography (EDI-OCT) in eyes of chronic heart failure (CHF) patients.
  
  
  METHODS
  Fifty-six patients with CHF and 56 age- and gender-matched healthy individuals were enrolled. The SFCT was measured by EDI-OCT. The ejection fraction of left ventricle (EFLV), age, intraocular pressure (IOP), axial length (AL), systolic and diastolic blood pressure, and ocular perfusion pressure (OPP) were also measured.
  
  
  RESULTS
  Mean SFCT was 181.2 ± 80.23 μm in the study group and 283.6 ± 52.4 μm in the control group (p = 0.000). There was a statistically significant correlation between the SFCT and each of EFLV and age. SFCT value was not statistically significantly associated with AL, IOP and OPP.
  
  
  CONCLUSIONS
  Our results suggest that SFCT is lower in eyes of CHF patients compared to age- and gender-matched healthy individuals.
