PURPOSE: To investigate the role of @entity2694 ( @entity2694 ) in the diagnosis of @entity13669 ( @entity13669 ) with anterior drainage and particularly whether a negative @entity2694 could avoid an invasive diagnostic cerebral angiography (DSA). MATERIALS AND METHODS: Twenty-two consecutive @entity1 with ophthalmic signs suspecting @entity13669 were submitted to ophthalmologic examination, @entity2694 and DSA. @entity13669 diagnosis with @entity2694 was based on the finding of a reversed, arterialized and low-resistive-index (RI <0.5) blood flow in the superior ophthalmic vein (SOV). Sensibility, specificity, @entity2286 , NPV, and accuracy of @entity2694 were calculated considering both @entity1 and eyes, using DSA as gold standard. RESULTS: DSA demonstrated 20 CCFs in 18 @entity1 . Considering the @entity1 , in 18/22 @entity13669 diagnosis was positive at @entity2694 and DSA while 4/22 were negative at both. Considering the eyes, in 24/43 @entity13669 diagnosis was positive at both DSA and @entity2694 (total eyes  =  43, due to one case of SOV @entity715 ). In 19/43 eyes diagnosis was negative at both @entity2694 and DSA. So sensitivity, specificity, @entity2286 , NPV, and accuracy of @entity2694 in the @entity1 and eyes analysis were all 100  %. CONCLUSIONS: @entity2694 is a reliable, noninvasive tool in the diagnosis of @entity13669 ; a negative @entity2694 could avoid an invasive DSA in @entity1 suspected for anterior-draining @entity13669 .
