Abstract: With the objective of analyzing the postaneurysmal peak systolic velocity (PSV) in ophthalmic arteries, duplex scanning was analyzed in 28 carotid-ophthalmic artery segments after exclusion of ipsilateral carotid stenosis, For comparison, the angiographic study of the extracranial and intracranial carotid system was utilized as the ''gold standard,'' A subgroup of 7 subjects with 8 ophthalmic arteries with aneurysms identified where the artery leaves the internal carotid artery presented with PSVs significantly reduced (mean PSVs 17.95 +/- 7.99 cm/s) compared to the mean PSVs in the healthy group (27.95 +/- 5.54 cm/s) (p = 0.006), A PSV of less than 19 cm/s offered a sensitivity of 80% and a specificity of 100% in diagnosing ophthalmic artery aneurysms, We conclude that duplex scan is diagnostically useful in the identification of patients with ophthalmic artery aneurysms when severe ipsilateral carotid stenosis is excluded, (C) 1997 World Federation for Ultrasound in Medicine & Biology.
