Retrobulbar haematoma in the era of anticoagulants.

Abstract

The present retrospective study aimed to evaluate the frequency and distribution of retrobulbar haematoma (RBH) among 26 patients (12 male/14 female) who had suffered maxillofacial trauma/surgery, with special focus on anticoagulants, causes of accidents, treatment, and outcome. Patient ages ranged from 8 to 94 years, with a mean of 65 years. Among all patients, 43% had received anticoagulant therapy at admission; 92.3% had a previous history of maxillofacial trauma. The most frequent cause of RBH were falls (65.4%), and three patients experienced RBH postoperatively after treatment using polydioxanone foil. Postoperatively (after RBH relief), 33.3% of the patients reported persistent complete visual loss; of these patients, 29% had received anticoagulation therapy, and the oral anticoagulant intake was not documented in further 29% of the patients. Awareness of this pathologic process is crucial for preventing permanent loss of vision via early diagnosis and adequate therapy. With increasing age, patients are more likely to receive an anticoagulant, which leads to a higher risk of RBH. Because falling was the most frequent cause of RBH in our patient population and increases in frequency with increasing age, fall prevention is crucial.
