Multimodal imaging of congenital peri-papillary arterial loops presenting with vitreous hemorrage in a young male: A case report.

INTRODUCTION

Congenital arterial peripapillary loops are rare entities and very few cases are described in literature.

CASE DESCRIPTION: A 25-year-old Asian man presented a diffuse vitreous hemorrhage in his Left Eye (LE). OCT-A revealed the presence of bilateral vascular loops at the optic nerve head. Fluorescein angiography (FA) confirmed the vascular abnormality in both eyes, with arterial filling in early phases and no dye leakage. At twenty days of follow up, the vitreous hemorrhage in the LE completely reabsorbed and BCVA improved from 20/63 to 20/20.

CONCLUSION

Congenital peripapillary loops should be considered in the differential diagnosis of vitreous hemorrhage, especially in young patients with no history of ocular/head trauma. Multimodal imaging is highly recommended to properly manage the patients, avoiding unnecessary therapeutic choices.
