技術名稱: 光學同調斷層掃描儀-雷射眼底鏡

技術簡介

OCT系統掃描時,為方便看到整個眼底視網膜之影像而開發,本系統利用低強度紅外光作為聚焦光源,掃描過程中不會使瞳孔縮小,無需散瞳劑。此外,本系統全眼底掃描過程花費時間比起眼球轉動時間更短,因此不會造成受測者的不適。

Abstract

SLO is designed to search for the image of the entire retina when the OCT system is scanned. This SLO system utilizes a low intensity infrared light as the source of focused light beam. Without mydriatic, the scanning process does not cause miosis. The whole retinal scanning process takes time shorter than eye movements, it does not cause any discomfort.
