[Platelet arachidonic acid and central retinal vein obstruction (author's transl)].

Study of 25 cases of obstruction of the central retinal vein. In the 4 first days it is a low level of arachidonic acid of platelet membrane. This fall of level is the one anomaly of fatty acid from platelet and plasma. We have obtained no correlation between the level of platelet AA and age or lipids level of the blood. Study of platelet agregation was performed in only some cases and no conclusion is possible.
