Temporal branch retinal vein occlusion secondary to a racemose hemangioma

Purpose:
To describe a case of venous thrombosis secondary to unilateral racemose hemangioma (RH).
Methods:
Biomicroscopic examination, fluorescein angiography, and optical coherence tomography were used. The patient was a 12-year-old girl who was seen for progressive loss of visual acuity in the left eye.
Results:
Examination revealed venous thrombosis in the superior temporal vein area in the context of arteriovenous malformation (AVM). Treatment with intravitreal triamcinolone (4 mg) resulted in anatomic and functional improvement.
Conclusion:
This was an exceptional case of branch retinal vein occlusion secondary to RH in a girl without known risk factors for venous obstruction. The obstruction was attributable to the large-caliber superior temporal artery, which, on forming a loop in the region of the venous branch, produced an obstruction of venous branch blood flow.
