Asymptomatic retinal emboli and current practice guidelines: a review.

Asymptomatic retinal emboli are found in 1-3% of patients on routine fundus examination.

This article will discuss the different aetiologies of retinal emboli and will present an overview of the recommended referrals for further systemic testing and treatment. It is important to communicate well with the primary care physician when asymptomatic retinal emboli are detected to ensure the appropriate investigations are undertaken.
