Insights
For elderly patients undergoing eye surgery, continuing antiplatelet and anticoagulant drugs is safer than stopping them. Discontinuing these medications increases the risk of dangerous blood clots more than the risk of bleeding during ophthalmic procedures.
Area of Science:
- Ophthalmology
- Cardiology
- Geriatrics
Background:
- Elderly patients frequently require ophthalmic surgery.
- Many elderly patients use antiplatelet and anticoagulant medications.
- Current practice often involves discontinuing antithrombotic therapy before surgery to prevent bleeding.
Purpose of the Study:
- To review the risks of discontinuing antithrombotic treatment versus continuing it for ophthalmic surgery.
- To evaluate the balance between bleeding complications and thromboembolic events in patients on antithrombotic therapy.
Main Methods:
- Narrative review of published literature.
- Analysis of risks associated with antithrombotic drug discontinuation.
- Assessment of bleeding versus thrombosis risks in ophthalmic surgery patients.
Main Results:
- Discontinuing antiplatelet or anticoagulant therapy significantly increases the risk of arterial or venous thromboembolic events.
- This increased thromboembolic risk is particularly notable in patients with atrial fibrillation, prosthetic heart valves, or recent coronary stenting.
- Ophthalmic bleeding events are typically minor and without severe consequences when antithrombotic therapy is maintained within the therapeutic range.
Conclusions:
- The risk of serious thromboembolic events from discontinuing antithrombotic drugs outweighs the risk of significant bleeding during ophthalmic surgery.
- Maintaining antiplatelet and anticoagulant therapy is recommended for most ophthalmic procedures.
- This recommendation holds true regardless of the anesthetic technique used.
Abstract:
The large majority of patients undergoing ophthalmic surgery are elderly and take systemic medications on a regular basis, including antiplatelet and anticoagulant treatments. It is current practice for many physicians to discontinue antithrombotic treatment prior to surgery to reduce bleeding complications that may lead to retrobulbar haemorrhage and, ultimately, to loss of vision. However, discontinuation of antithrombotic treatment in such patients may lead to thromboembolic events with serious consequences. The present narrative review highlights the risk of thrombosis when discontinuing antithrombotic drugs and the risk of bleeding when continuing them. The published literature on this topic shows that discontinuation of antiplatelet or anticoagulant treatment leads to a substantially increased risk of arterial or venous thromboembolic events and related complications, especially in patients with atrial fibrillation, prosthetic heart valves or recent coronary stenting. This risk is distinctly higher than the risk of significant local haemorrhage. Ophthalmic bleeding events reported in the literature are usually minor, without serious consequences, even if antiplatelet or anticoagulant treatments are continued, provided that the anticoagulation level is within the therapeutic range. Thus, the current data are in favour of maintaining antiplatelet and anticoagulant drugs for most ophthalmic procedures, regardless of the anaesthetic techniques.
