Standard optical systems in ophthalmology are strictly dedicated either to retinal or to anterior segment imaging due to the refractive properties of the eye. We demonstrate a swept source optical coherence tomography platform with an electrically tunable lens (ETL) for versatile 3D in vivo imaging of both the eye’s anterior segment and the retina. The optimized optical setup with adaptive operational states of the ETL permits focusing on the retina and on the anterior segment. Dynamic control of the optical beam focus allows for OCT image enhancement, leading to the visualization of the vitreous details at both the vitreo-lenticular and vitreo-retinal attachment sites in an unprecedented manner. ETL tuning enables sequential visualization of the anterior and posterior segment of the eye, and such whole eye imaging can be also used to perform quantitative ocular biometry.

扫频光源光学相干层析成像和可调透镜技术，可对整个眼睛进行全面成像和生物测定

眼科的标准光学系统由于眼睛的屈光特性而严格地专用于视网膜或前段成像。我们演示了具有电可调透镜（ETL）的扫频光学相干断层扫描平台，可用于体内多种3D眼睛的前段和视网膜的成像。具有ETL自适应操作状态的优化光学设置允许聚焦在视网膜和前节上。光束聚焦的动态控制可以增强OCT图像，从而以前所未有的方式可视化玻璃体-双凸透镜和玻璃体-视网膜附着部位的玻璃体细节。ETL调整可对眼睛的前段和后段进行顺序可视化，并且这种全眼成像也可用于执行定量眼部生物统计。
