Abstract

Purpose

To evaluate the effects of atrial fibrillation (AF) and ablation procedures on electrophysiological function in the retina and optic nerve.

Methods

Thirty two eyes of 17 patients with AF were analyzed. The full-field electroretinogram (ERG), pattern electroretinogram (PERG) and pattern visual evoked potential (PVEP) were performed. The results were compared to age-matched healthy controls (n = 30). In 12 eyes, electrophysiological tests were performed before and 3 months after ablation treatment.

Results

Statistically significant differences between AF patients and healthy controls were detected. In the full-field ERG, a reduction in the oscillatory potentials wave index (OPs WI; p = 0.012) and scotopic (0 dB) a-wave amplitude (p = 0.009) was observed. The amplitude of b-waves, scotopic (24 dB; p = 0.011), photopic single flash (p = 0.008) and photopic flicker (p = 0.009), was decreased. The photopic flicker b-wave peak time was increased (p = 0.005). Other parameters of ERG/PERG/PVEP did not differ significantly from controls. After the ablation procedure, the only statistically significant change was an increase in the OPs WI (p = 0.002).

Conclusions

In the analyzed series of AF patients, retinal dysfunction was detected in the ERG test. The AF ablation may improve the retinal function as indicated by an increase in the OPs WI. The OPs WI has a potential value in the estimation of the effectiveness of AF ablation.
