[Central retinal artery occlusion following coronary angiography: a case report]

Central retinal artery occlusion after catheter ablation of atrial fibrillation

Central retinal artery occlusion (CRAO) is a rare but severe and urgent complication of atrial fibrillation ablation. Awareness of this ophthalmologic complication and prompt treatment are needed because ischemic damage to the retina is irreversible from 4 hours after the onset of CRAO.

Branch Retinal Artery Occlusion after Percutaneous Coronary Intervention

We report a case of branch retinal artery occlusion (BRAO) that occurred after percutaneous coronary intervention (PCI). A 59-year-old man with no other previous diseases presented visual acuity deterioration in the left eye 24 hours after PCI. Fundus examination revealed ischemia at the temporal branch of the retinal artery associated with inner layer edema. Prompt treatment was performed with ocular digital massage and paracentesis of the anterior chamber. However, at discharge, the patient had a persistent visual loss with a central scotoma that persisted at 35-day follow-up without improvement of the visual acuity. The patient did not suffer from any other systemic complications. Retinal infarction should be considered a potential complication of PCI. Patients and health care providers should be aware of any visual signs. Permanent visual disability can be prevented by immediate diagnosis and prompt intervention.

En Face Optical Coherence Tomography Imaging of Deep Capillary Plexus Abnormalities in Paracentral Acute Middle Maculopathy

The authors describe a case of para-central acute middle maculopathy (PAMM) in a 75-year-old man who had recently undergone cardiac catheterization. Imaging with simultaneous en face optical coherence tomography (OCT) and OCT angiography (OCTA) revealed signal abnormalities localized to the deep capillary plexus. This case highlights the ability of OCTA to image and localize retinal disease by vascular distribution, previously difficult with conventional fluorescein angiography, and lends evidence to the belief that PAMM is caused by vascular injury to the intermediate and deep capillary plexus.

Why can't I see after my heart is fixed: a case series of ocular complications after cardiac intervention

Background

The purpose of this study was to report case series of retinal artery occlusion (RAO) as one of the significant complication post cardiac intervention.

Case presentation

We are reporting one case of branch RAO and one case of central RAO after percutaneous coronary intervention (PCI). In case 1, a 74-year-old gentleman with pre-existing diabetes mellitus and hypertension was electively admitted for PCI for coronary artery disease (CAD) in our centre (UKMMC). Few hours after the procedure, patient complained of sudden blurring of vision in the right eye. He was found to have branch retinal artery occlusion. In case 2, a 49-year-old gentleman presented with ST segment elevation myocardial infarction (STEMI) and had an emergency PCI performed 2 h upon admission. He noticed sudden dropped of vision in his right eye immediately after the procedure. He was diagnosed to have central retinal artery occlusion.

Conclusions

In conclusion, retinal artery occlusion is a possible complication post PCI. Patients need to be informed especially in high risk cases.
