In a retrospective study, @entity1 with 125 ocular arterial occlusions (71 @entity1 , 54 @entity1 ) observed between 1978 and 1981 were analyzed with regard to etiology, therapy, and course of disease. Particular attention was given to information obtained by means of Doppler sonography. Among our @entity1 the most common condition was occlusion of either the central retinal artery or its branches (62 cases), as opposed to 30 @entity1 with @entity1829 , 6 with chronic @entity63 (or @entity63 ), and 4 with less common types of occlusion. In the @entity1 collective as a whole, the causes in those over 50 years of age are predominantly hypertony, @entity4288 , and emboli, as well as other causes which cannot be determined with certainty. If occlusions of the central artery and its branches and @entity1939 fugax are considered alone, emboli are by far the most common cause. According to the findings with Doppler sonography, the most frequent source of emboli appears to be the bifurcation of the carotid artery. A chronic @entity63 (also known as @entity63 ) is always indicative of obstruction of the carotid artery. The situation is completely different in @entity1829 , which is, as a rule, either secondary to an affection of the smaller vessels, hypertonically @entity1294 , or caused by @entity32 , as is the case in temporal arteriitis. Doppler sonography is of paramount importance as a simple, non-invasive method for determining the pathogenesis of ocular @entity432 . It also provides pointers to further clarifications which could lead to bypass surgery being indicated. In those @entity1 in whom such examinations were possible, the findings were pathologic in all cases of chronic @entity63 (6 out of 6), in 84% of the cases of @entity1939 fugax, in 62.5% of the cases of occlusion of the central artery or its branches, but only in 23% of the cases of @entity1829 , which further distinguishes this later condition from the other forms of occlusion. Frequently suggested therapies, for example RheomacrodexR, failed to produce any convincing results in our @entity1 collective - not only those with central @entity715 but also those with @entity1829 . In a statistical comparison, no significant difference could be demonstrated between our treatment of @entity1829 without corticosteroids (as long as arteriitis temporalis was not involved) and that of Hayreh, who administered corticosteroid treatment not only for @entity1829 but also for @entity1294 conditions of the optic disk induced by @entity101 .(ABSTRACT TRUNCATED AT 400 WORDS)
