(26B1-16) 中心性滲出性脈絡網膜症23例24眼のICG造影所見を検討した。本症においてICG造影により造影早期および晩期ともに脈絡膜新生血管が検出できた典型的新生血管は18眼(75%),造影早期もしくは晩期どちらかでのみ新生血管が検出できた非典型的新生血管は2眼(8%),新生血管が造影を通して検出できなかったものが4眼(17%)あった。典型的新生血管を検出できた症例では,新生血管周囲の低螢光輪(dark rim)が89%と高率にみられ,dark rimが造影晩期まで明瞭なものはICG造影後6か月以内に病巣が瘢痕化した例が多く,ICG造影における脈絡膜新生血管周囲のdark rimの鮮明度は,予後判定に重要な臨床所見となる。
We performed indocyanine green (ICG) angiography in 24 eyes of central exudative chorioretinopathy. Typical choroidal neovascularization (CNV) was detected in 75% of the eyes. Atypical CNV was present in 8% of the eyes. No CNV was detected in 17% of the eyes. A dark rim surrounded the CNV in 89% of typical CNV. In the majority of eyes with dark rim throughout the phases of ICG angiography, the CNV started to regress within 6 months. These findings show that the dark rim around the CNV in ICG angiogram is useful in the evaluation of future clinical course in cases of central exudative chorioretinopathy.
