In the Discussion section, the authors cited White et al., PNAS, 2017, whose work shows a reactive monocyte response following metronidazole-mediated rod photoreceptor ablation in zebrafish. The authors neglected to mention that, in addition to histological analyses, White and colleagues also carried out in vivo time-lapse/time-series imaging after ablation showing macrophage and microglial reactivity, which promotes rod regeneration. The publication from the Mumm lab and this work are complementary, applying analogous time-resolved methods at larval and adult stages, respectively, to visualize aspects of the regenerative response in vivo.
The following sentence has been added to the second paragraph of the Discussion in the article online: “White and colleagues50 have also used in vivo time-lapse imaging to show peripheral macrophages and retinal microglia exhibiting migratory morphologies along with increased cell migration dynamics after metronidazole-mediated rod ablation.”
