Quantitative Topographic and Tomographic Measurements of the Human Retina by Dual Beam Partial Coherence Interferometry

Abstract

Direct imaging of the human retina in vivo and quantitative measurements of the thickness of its layers is one of the major challenges of ophthalmic instrumentation during the last years. The diagnostics of several ocular disorders might benefit from the solution of this task. The importance of this task is demonstrated by several recent technical approaches, including stereo video ophthalmoscopy1, laser tomographic scanner2, scanning laser polarimetry3, and optical coherence tomography (OCT)4,5.
