Antiphospholipid syndrome (APS) is an autoimmune disease characterised by a heterogenous group of antibodies directed against negatively charged phospholipids including antiphospholipid antibodies (aPL), anticardiolipin antibodies (aCL) and beta-2 glycoprotein I (abeta-2-GP1). The major features of this disorder include arterial and venous thrombosis and recurrent fetal loss. The vasculature of the eye is frequently involved and may be the presenting manifestation. A diagnosis of APS should be considered in a young patients without traditional thromboembolic risk factors presenting with ocular vaso-occlusive disease. Management of these patients involves a team-approach with a haematologist/oncologist or rheumatologist to manage the coagulation status of these patients to prevent further systemic vascular occlusions.
