Retinal artery occlusion, Retinal vein occlusion, Antiphospholipid antibodies, Posterior ischemic optic neuropathy, Lupus anticoagulants, Anticardiolipin antibodies, Anterior ischemic optic neuropathy
Purpose: It was the aim of this study to evaluate antiphospholipid antibodies (APA), i.e. lupus anticoagulants (LA) and anticardiolipin (ACA) IgG and IgM, in ophthalmic occlusive disease. Methods: Over a 3.5-year period, APA were evaluated in 368 patients. Results: Eighty-six patients (23.4%), compared to 5% in the general population, tested positive for APA. APA did not differ significantly between patients with venous (20.6%) or arterial (25.5%) occlusive disease. This included 93 patients with central retinal vein occlusion (18% APA positive), 67 with retinal branch vein occlusion (24% APA positive), 41 with central retinal artery occlusion (22% APA positive), 53 with retinal branch artery occlusion (32% APA positive), 71 with anterior ischemic optic neuropathy (23% APA positive), 12 with posterior ischemic optic neuropathy (33% APA positive) and 31 patients with amaurosis fugax (23% APA positive). Excluding patients with accepted main risk factors, APA were positive in 15.3% of 85 patients. Conclusion: The high APA prevalence confirms its relevance in ocular occlusive disorders.
