Three-dimensional (3D) volumetric imaging of the human retina is instrumental to monitor and diagnose blinding conditions. Although coherent retinal imaging is well established by optical coherence tomography, it is still a large void for incoherent volumetric imaging in the human retina. Here, we report confocal oblique scanning laser ophthalmoscopy (CoSLO), to fill that void and harness incoherent optical contrast in 3D. CoSLO uses oblique scanning laser and remote focusing to acquire depth signal in parallel, avoid the lengthy z-stacking, and image a large field of view (FOV). In addition, confocal gating is introduced by a linear sensor array to improve the contrast and resolution. For the first time, we achieved incoherent 3D human retinal imaging with >20° viewing angle within only 5 seconds. The depth resolution is ~45 microns in vivo. We demonstrated label-free incoherent contrast by CoSLO, revealing unique features in the retina. CoSLO will be an important technique for clinical care of retinal conditions and fundamental vision science, by offering unique volumetric incoherent contrasts.

The first images of the living human retina were published in 1886. In the 125 years since then, clinicians and researchers alike have relied on the continued development of new and improved ways to visualize the fundus to provide better in vivo views of the normal and diseased retina. Adaptive optics-based technologies offer non-invasive, cellular resolution views of the living retina, and bring with them several exciting clinical applications. Here we review some of these applications, with an emphasis on photoreceptor imaging.
