[Anticardiolipin antibodies in vascular occlusions of the eye].

Elevated levels of anticardiolipin antibodies (ACA) have recently been found to be associated with occlusive diseases such as myocardial or cerebral infarction or venous thrombosis. In a prospective study anticardiolipin antibodies (both IgG and IgM) were measured by ELISA in 140 patients with acute vascular occlusions of the eye. Patients with clinical evidence for lupus erythematodes, HIV infection or elevated concentrations of antinuclear antibodies (IIFT with HEp-2 as antigen, LD Diagnostika, Heiden, FRG) were excluded. Elevated concentrations of IgG-ACA and IgM-ACA were found in 9% of the cases, with no correlation with the type of ocular vascular occlusion (retinal artery occlusion, retinal vein occlusion, anterior ischemic optic neuropathy). These results indicate that the anticardiolipin syndrome with elevated concentration of anticardiolipin antibodies may also have a causal role in some patients with occlusive eye diseases, whereas in most patients the concentrations were within normal ranges.
