Abstract

Purpose : To evaluate the difference of the retinal vascular perfusion especially in the deep slab between in the affected and unaffected eyes in patients with unilateral amaurosis fugax.

Methods : Fourteen eyes of seven patients with unilateral amaurosis fugax in the past were performed OCT Angiography 6x6mm cube scan using Ver. 10.0 AngioPlex on the Cirrus HD-OCT model 5000. Then, Vascular Perfusion in the deep slab was calculated in predefined ETDRS segments which are in the Central, Inner, Outerl, Inner upper, Inner lower, Inner nasal, Inner temporal, Outer upper, Outer lower, Outer nasal and Outer temporal regions.

Results : Vascular Perfusion showed a significant difference between in the affected and unaffected eyes in the almost all of regions (P=0.017), the Inner, Outer, Inner upper, Inner lower, Inner nasal, Outer upper, Outer lower, the Outer temporal (P=0.023), the Inner temporal (P=0.027) and the Central (P=0.043) except in the Outer nasal (P=0.128).

Conclusions : I reported in amaurosis fugax, the superficial retinal vascular perfusion in the affected eyes was decreased in the all regions except the Outer nasal regions, previously. This time, the deep retinal vascular perfusion in the affected eyes was also decreased in the all regions except the Outer nasal regions.
