In a bid to overcome the challenges associated with acquiring retinal images from young children, and to increase image resolution, a team at Duke University have been developing an ultracompact handheld SLO/OCT probe (Figure 1). Having demonstrated  their device obtains high-resolution retinal images in children as young as 14 months of age (1), Cynthia Toth, Joseph Izatt, and Francesco LaRocca tell us more…
