OCT angiographyでは右眼(A)と左眼(D)の浅層血管複合で不整な中心窩無血管域と右角静脈を認め、深層血管複合では右眼(B)と左眼(E)で血管侵入と傍中心窩の毛細血管拡張、無血管複合では右眼(C)と左眼(F)で多枝性異常吻合を伴う新生血管網を示す。本文「2. 主な症状と臨床所見」の項で扱う毛細血管拡張に対応する。
Red free画像では黄斑部にリング状もしくは横楕円形の高反射像を示す。10) この所見はMacTel type 2に特異的であり、病初期から認められるため診断に有用である。10) 共焦点走査レーザー検眼鏡(confocal blue light reflectance: CBR)でより明瞭に観察される。10)
