The brachial artery pressure and retinal artery pressure responses to a one-minute cold pressor test were evaluated simultaneously in 14 @entity1 with @entity6 (six with and eight without @entity6 ) and 10 age-matched control subjects. Five @entity1 with @entity1723 had @entity4148 . Mean baseline brachial artery pressure and retinal artery pressure were similar in @entity1 with @entity1723 and control subjects. After cold pressor testing, the brachial artery pressure increased significantly (p less than 0.01) compared with baseline values in both groups. Retinal mean arterial pressures increased significantly (p less than 0.001) after cold pressor testing compared with the baseline values only in @entity1 with @entity1723 . Positive correlation was found between the brachial and retinal mean arterial pressures after cold pressor testing (r = 0.48; p less than 0.05) in the @entity6 @entity1 but not in the control subjects (r = 0.10; p = NS). No correlation was found between the retinal artery pressure and age of onset of @entity6 , duration of @entity6 , the presence or absence of @entity6 , and glycemic control. Four @entity1 with @entity258 , which remained unchanged after cold pressor testing, had no @entity6 . The fifth @entity1 with @entity4148 and exaggerated systolic brachial artery pressure (175 mm Hg) and retinal artery pressure (more than 80 mm Hg) responses had severe background @entity6 . In conclusion, abnormal retinal artery responses to stress are present in @entity1 with @entity1723 . This may be modified by the presence or absence of both @entity4148 and @entity101 . The biologic significance of these findings is yet to be determined.
