Migration of segmental arteriolar fluorescein staining peripherally in eye with idiopathic recurrent branch retinal arterial occlusion

Abstract

Purpose: To report a novel finding in a case of idiopathic recurrent branch retinal arterial occlusions. Observations: We report our findings in a 31-year-old woman with an idiopathic recurrent branch retinal arterial occlusions (BRAOs) who was followed in our clinic for 16 years. Repeated fluorescein angiographies were performed to evaluate the idiopathic recurrent BRAOs. The findings showed multiple segmental arteriolar staining in the fundus. These staining were found at locations with and without branch retinal arterial occlusions. Repeated fluorescein angiography showed that these staining migrated toward the periphery. The speed of the migration of the staining was about 0.64 ± 0.22 mm/day with a range of 0.43–0.85 mm/day in the posterior pole of the eye. In each of the BRAO, the staining did not cause branch retinal arterial occlusions in the peripheral retina again. Conclusions and importance: Segmental arteriolar staining that migrates towards the periphery may be a clue to the etiology of this disease process
