Importantly, the investigators also noted: “Continuing anti-thrombotic agents peri-operatively may increase the risk of potentially sight-threatening haemorrhagic complications, whereas discontinuing these medications may increase the risk of life-threatening thromboembolic events. Therefore, it is important to understand the indications of anti-thrombotic agents and when it may be safe to discontinue them peri-operatively.”
They also believed that it was important to stratify the ophthalmic surgeries depending on the risk of development of hemorrhagic complications during the perioperative period.
Based on these concerns, they conducted a PubMed search from January 2007 to August 2017 to identify articles that provided recommendations on managing antithrombic agents during the perioperative period of ophthalmic surgeries and reviewed the incidence rates of the associated hemorrhagic complications. They also reviewed all guidelines in the UK from the Royal College of Ophthalmologists and British Society of Haematology.
