SD-OCT in NIR modality to diagnose retinal microvascular abnormalities in neurofibromatosis type 1

We identified three different vascular patterns based on their appearance: (i) the simple tortuosity; (ii) the more complex corkscrew; and iii) the moya moya-like configurations. In the “corkscrew” pattern, we identified a spiral attitude of vessels, while the moya moya-like configuration was characterized by tortuous vessels that end in a “puff of smoke” arrangement that resembles the collateral circulation seen in moya moya syndrome..
