Subfoveal choroidal thickness and retinal nerve fiber layer alterations in chronic heart failure patients

Our study thus revealed that the subfoveal choroidal thickness was lower in patients belonging to both the chronic heart failure groups in comparison to those in the control group. However, the alteration in the peripapillary retinal nerve fiber layer thickness was noted in only patients with <30% left ventricle ejection fraction. In the clinical practice, reductions in these values are correlated with decreased left ventricle ejection fraction, which may be important for the follow-up of chorioretinal diseases and the evaluation of glaucoma risks in patients with chronic heart failures.
