[No disorder of arachidonic acid-induced thrombocyte aggregation in familial exudative vitreoretinopathy].

Six patients, members of a family with familial exudative vitreoretinopathy (FEVR), were studied to verify whether the disease was associated with a suspected platelet aggregation defect. No hemostaseologic defect was found in either the affected or healthy members of the family; in particular, there were no grounds for suspecting any disturbance of arachidonic acid-induced platelet aggregation.
