In 2010, this journal published a series of review articles in a Thematic Issue entitled “Lipids and Lipid Metabolism in the Eye.” Over the ensuing decade, a number of significant advances have been made that are pertinent to this broad topic, which prompted us to launch a follow-up Thematic Issue to present updates on several of the topics reviewed in that prior issue as well as to expand into new areas that previously had not been addressed. In addition to considering the conventional classes of lipids (e.g., glycerophospholipids, sphingolipids, fatty acids, and sterols), we also wanted to address some key lipid-soluble molecules (e.g., retinoids, bisretinoids, and carotenoids) that play important physiological roles in ocular tissues.
