    To restore sight after retinal degeneration, one approach is to express light-sensitive proteins in remaining cells. Here the authors combine a light-sensitive engineered G protein-coupled receptor and ion channels to restore ON and OFF responses as well as superior visual pattern discrimination.

    Large electronics limit low-noise, non-invasive electrophysiological measurements to a thousand simultaneously recording channels. Here the authors build an array of 65k simultaneously recording and stimulating electrodes and use it to sort and classify single neurons across the entire mouse retina.

    Rod photoreceptors are thought to be saturated under bright light. Here, the authors describe the physiological parameters that mediate response saturation of rod photoreceptors in mouse retina, and show that rods can drive visual responses in photopic conditions.

    Retinal rod bipolar cells (RBCs) partially undergo programmed cell death triggering cell density-dependent plasticity. This study shows that increased removal of RBCs using genetic approaches causes dendrites of the remaining RBCs to expand and contact more rod photoreceptors while reducing connectivity with each.

    How a neuron integrates sensory information requires knowledge about its functional presynaptic connections. Here the authors report a new method using non-negative matrix factorization to identify the layout of presynaptic bipolar cell inputs onto retinal ganglion cells and predict their responses to natural stimuli.

    Integration of transplanted photoreceptors into the host retina has been assumed as the underlying mechanism for vision improvement in pre-clinical studies. Here, the authors show that the majority of transplanted photoreceptors do not structurally integrate but exchange intercellular material with host cells.

    Transplantation of healthy photoreceptor cells has been shown to rescue blindness. Here, the authors show that rather than donor cells integrating into the host retina, the predominant mechanism underlying this rescue involves exchange of cytoplasmic material between donor and host cells in vivo.

    Retinal waves are important for visual system development. However, the mechanism involved in their generation remains largely unknown. Here using in vivotwo-photon imaging the authors identify the presence of retinal waves in zebrafish larvae and find that they are initiated at bipolar cells via presynaptic NMDARs.

    The mammalian retina is a modular brain region, in which cell layers are of uniform thickness but the molecular mechanism controlling this process is not well understood. Here the authors identify a regulatory network consisting of the long noncoding RNA Rncr4, RNA helicase Ddx3x and miR-183/96/182 that controls the even distribution of cells across layers.

    The transcriptional regulation of morphogenetic effectors during eye development is poorly understood. Here, the authors show that transcription of an endocytosis regulator Opois crucial for the neural retina development in zebrafish and activated by the interaction of the transcription factor Vsx2 and retinal enhancer H6_10137.

    The ciliary margin of the eye functions as a source of multipotent progenitor cells in certain organisms but whether it plays this role in humans has not been easy to study. Here the authors culture human embryonic stem cells that self-organize into retinal tissue, and show that ciliary margin-like growth zones emerge from the developing human retinal tissue and contain stem cell niches.

    Populations of the cave fish Astyanax mexicanus exhibit a variety of traits that evolved repeatedly and independently from its surface counterparts. Here the authors present a de novo genome assembly for A. mexicanusand identify candidate genes for eye loss and reduced pigmentation.

    Components of the complement system have been shown to promote liver regeneration. Haynes et al. demonstrate that the complement fragment C3a can induce regeneration of the embryonic chick retina from stem and progenitor cells of the ciliary margin via activation of STAT3 and other downstream signalling pathways.

    The central nervous system contains glial cells, which have been shown to have an important role in neuronal survival. Haradaet al. use transgenic mouse models to show that TrkB, a receptor for the growth factor brain-derived neurotrophic factor, is required for retinal Müller glial cells to provide neuroprotection and regeneration.
