Whole Eye Optical Coherence Tomography Imaging

Many eye diseases will affect the shape and dimensions of the whole eye. For examination of ocular accommodation and pathological changes caused by these diseases, high resolution imaging of the whole eye segments OCT system is needed. However, limited by the imaging depth, traditional Fourier Domain Optical Coherence Tomography (FDOCT) can’t be used for real time whole eye segment imaging. In recent years, techniques for depth extended FD-OCT system especially for whole eye segment imaging has been developed. Application on eye parameters measurement and eye accommodation studies were successfully performed. In this paper, both of whole eye FD-OCT techniques and their application were reviewed. Potential clinical application of these techniques may be in the detection of the pathological changes of the whole eye, and whole eye segment FD-OCT system also provides a powerful imaging method for ophthalmic research, such as accommodation, ocular growth, and biometry of the eye.
