Central retinal artery occlusion as a first sign of atrial fibrillation: A 3‐year retrospective single‐center analysis.

Background: Central retinal artery occlusion ((C)RAO) is known to be associated with stroke and/or atrial fibrillation (AF). Nevertheless, patients often present at the ophthalmologist initially and it is unknown how many of these receive an adequate cardiological/neurological work‐up (CWU/NWU), including a 24 h‐Holter‐ECG. Hypothesis: Hypothesis of this study was that patients with (C)RAO do not undergo CWU on regular basis and that new‐onset AF is more often detected in patients with CWU. Methods and results: We performed a retrospective analysis of n = 292 consecutive patients who presented at an ophthalmology department with the diagnosis of (C)RAO during a 3‐year period. After excluding patients with known AF, meeting exclusion criteria, inability to comply with the protocol, missed land phoneline, or death during follow‐up a total of 174 patients were enrolled; mean follow‐up was 20 ± 12 months. The CHA2DS2‐VASc score of the cohort was 5.3 ± 1.4. Our analysis revealed that only 50.6% of patients received a CWU including a single Holter‐ECG after the index‐event. In 12.6% cases new‐onset AF was diagnosed, while the rate was higher in patients with CWU compared to patients without CWU (18.2 vs. 7.0%; p = 0.26). Evaluation of oral anticoagulation (OAC) therapy showed that only 66% of patients with AF were treated according to guidelines. Conclusion: Only half of patients with (C)RAO underwent CWU. Despite minimal monitoring, rate of new diagnosed AF was high. Our results confirm that (C)RAO identifies a high‐risk population for AF. These results illustrate the importance to implement standardized CWU in (C)RAO patients presenting at the ophthalmologist. [ABSTRACT FROM AUTHOR]
