Optical coherence tomography (OCT) enables non-invasive depth-resolved imaging of the retina with micrometric precision. By exploiting low-coherence interferometry, OCT provides three-dimensional structural information together with sensitivity to nanometric optical path length variations in living tissue.

Phase contrast imaging reveals translucent structures by converting phase variations into detectable intensity differences. In the retina, this mechanism enables visualization of cells and microvascular structures that remain poorly contrasted in conventional reflectance imaging.

The retina is the only part of the central nervous system that can be imaged non-invasively at cellular resolution. This unique accessibility enables simultaneous measurement of light-evoked neuronal responses and associated microvascular dynamics in vivo.
