We demonstrate the capability of full-range complex (FRC) spectral domain optical coherence tomography (SD-OCT) to image the anterior eye segment from the cornea to the posterior surface of the lens. With an adapted spectrometer design, we developed a SD-OCT system with an extended normal (single half-space) depth range of 7 mm (in air). This OCT-intrinsic depth range was doubled with a FRC technique. We demonstrate the performance of our OCT system by imaging the whole anterior segment of a healthy human eye in vivo.
We demonstrate the capability of spectral domain optical coherence tomography (SD-OCT) with a full range complex
(FRC) technique to image the anterior eye segment from the cornea to the back surface of the lens. We improved the
spectrometer resolution with an adapted spectrometer design to achieve a single depth range of 7 mm in air. This depth
range was doubled to an imaging range of 14 mm with a FRC-technique based on phase modulation introduced by off
pivot point illumination of the galvanometer scanner. The performance of our system is demonstrated by recorded 2D
and 3D datasets of the whole anterior eye segment of healthy human eyes in vivo. The system is also applicable to
demonstrate the changes of the anterior eye segment during the accommodation of the eye.
We present the unique ability of polarization-sensitive optical coherence tomography to assess retinal disorders in a
quantitative way. Areas of atrophic zones and volumes of subretinal fluids were evaluated.
