简要总结
Accumulating evidence suggest that the functional unit of photoreceptor/ retinal pigment epithelium (RPE)/Bruch's membrane/choriocapillaris plays a key role in pathophysiologic processes of a wide range of medical retinal disorders of the eye. Little is known about in vivo morphometric characteristics of human RPE cells as in vivo observation of these cells was so far technically challenging and hence nearly impossible to implement in a clinical setting. Transscleral optical phase imaging is a novel in-vivo microscopy technique allowing human RPE imaging on a cellular level with the potential of clinical application in a multimodal retinal imaging approach for diagnostic purpose in medical retina patients.
