Choroidal Retinal Anastomosis in Age-Related Macular Degeneration as Demonstrated by Fluorescein Angiography- A Case Report

由眼底螢光攝影證實在年老性黃斑部病變病例合併有脈絡膜視網膜血管吻合-病例報告

摘要


病理性脈絡膜視網膜血管吻合的病例相當的少有。它曾被報告在年老性黃斑部病變病例合併有纖維性瘢痕,視網膜色素層剝離,或是在有活動性繁殖期的典型脈絡膜血管新生時期。我們報導一例52 歲女性有單側性的老年性黃斑部病變,在病變中有盤狀瘢痕合併隱藏性脈絡膜血管新生,在瘢痕中包 含一條脈絡膜視網膜血管吻合,其血流的方向是從脈絡膜新生血管流到視網膜靜脈。眼底螢光攝影能清晰地證實此條吻合血管。

Pathological choroidal retinal anastomosis is relatively rare. It has been described in age-related macular degeneration (AMD) with fibrous scarring or occult pigment epithelial detachment or actively proliferating classic choroidal neovascular membrane (CNV). We report a case of disciform macular scar with the occurrence of a choroidal retinal anastomosis, which directed blood flow from an occult choroidal neovascular membrane into a retinal vein through the fovea in a 52-year-old female with unilateral AMD. Fluorescein angiography (FA) clearly demonstrated the anastomosis.
