Retinal emboli in cholesterol crystal embolism

Area of Science:

• Cardiovascular Medicine
• Nephrology
• Ophthalmology

Background:

• Cholesterol crystal embolism (CCE) is a rare, severe multisystemic disorder.
• It arises from cholesterol crystal release secondary to atherosclerotic disease.
• CCE can lead to multivisceral failure and death, presenting diagnostic challenges due to varied symptoms.

Purpose of the Study:

• To highlight the diagnostic utility of fundoscopic examination in identifying retinal emboli in CCE.
• To emphasize the importance of prompt diagnosis for appropriate management of CCE.
• To present a case where fundoscopy confirmed CCE, averting further invasive procedures.

Main Methods:

• Case report of a 77-year-old male presenting with acute renal failure post-coronarography.
• Diagnostic confirmation through fundoscopic examination revealing retinal emboli.
• Review of CCE management principles, including cessation of anticoagulation and avoidance of endovascular procedures.

Main Results:

• Retinal emboli observed during fundoscopy confirmed the diagnosis of cholesterol crystal embolism.
• This finding precluded the need for additional invasive diagnostic investigations.
• The case underscores the critical role of ophthalmologic findings in CCE diagnosis.

Conclusions:

• Fundoscopic examination is a valuable, non-invasive tool for diagnosing cholesterol crystal embolism when suspected.
• Early detection of retinal emboli can expedite management and improve patient outcomes.
• Management strategies include stopping anticoagulants, avoiding endovascular procedures, considering peritoneal dialysis, and potential use of systemic corticosteroids.
