摘要

雷射是治療老年性黃斑病變合併脈絡膜新生血管最主要的治療方法，但是治療後仍有很高的再發率，因此，術後的評估及定期追踪顯得格外重要。以往我們均是以螢光眼底攝影做為評估的工具；本篇研究則是以循化綠眼底攝影做為評估工具，我們發現雷射治療三天後的區域在循化綠攝影為低螢光顯影，而雷射役有治療到的新血管為高螢光顯影。相對於眼底螢光攝影在雷射後射區域及新生血管均有明顯的螢光劑外洩和高螢光顯影，循化綠攝影對於雷射治療顯然有較佳的評估。

Laser treatment is the major and most freqently used method in the management of choroidal neovascularization, especialy in age related macular degeneration. However, high recurrent rate limits its effectiveness. Post laser evaluation and long term follow up thus are of great importance. Fluorescein angiography is the conventional method for evaluation of post-laser lesions. In this study, in docyanine green videoangiography is utilized for the immediate post laser evaluation. In our study, laser treated area was noted to be hypofluorescent and laser missed neovascularization was noted to be hyperfluorescent. No profuse dye leakage in the lesion area was present as that in fluorescein angiography. We found that indocyanine green videoangiography was a useful tool for immediate post-laser evaluation of choroidal neovascularization.
