Management of Antiplatelet Therapy Before Retina Surgery

Rationale for Discontinuation

The American College of Cardiology recommends discontinuing clopidogrel at least 5 days before surgery to minimize bleeding risk, as clopidogrel inhibits platelet aggregation for the lifetime of the platelet (7-10 days) 1, 2, 4, 5

High thrombotic risk patients, such as those with drug-eluting stents placed within 12 months or recent acute coronary syndrome, require cardiology consultation before discontinuing clopidogrel, according to the American Heart Association 3, 5
Low thrombotic risk patients, such as those with ischemic heart disease without coronary stents, are safer to discontinue clopidogrel, as stated by the European Society of Cardiology 3, 5

The American College of Chest Physicians recommends discontinuing clopidogrel 5 days before retina surgery to minimize bleeding risk, and resuming clopidogrel as soon as hemostasis is achieved, typically within 24-48 hours after surgery 1, 2
For high thrombotic risk patients, the American College of Cardiology suggests considering continuing aspirin if the patient is on dual antiplatelet therapy, and consulting cardiology for risk assessment and management plan 5, 6

Discontinuing clopidogrel too close to surgery (less than 5 days) increases bleeding risk, as stated by the American College of Chest Physicians 1
Stopping antiplatelet therapy for too long in high-risk cardiac patients can lead to stent thrombosis, according to the American Heart Association 5

Retina surgery involves operating in a closed space where bleeding can significantly impact surgical outcomes and visual prognosis, as noted by the American Academy of Ophthalmology 1
The American College of Chest Physicians guidelines can be modified on a case-by-case basis for surgeries with high bleeding risk, such as retina surgery, to minimize bleeding risk 1, 2
