Outdoor segment lipidomics revealed selective remodelling of phosphatidylcholine and phosphatidylethanolamine species toward more oxidation-resistant and elongated acyl chains, supported by early gene upregulation of essential enzymes involved in fatty acid elongation, desaturation and oxidation.
Diabetic retinopathy (DR) is a major cause of preventable visual impairment and develops through intertwined metabolic, oxidative, inflammatory, and neurovascular disturbances. This review examines how chronic hyperglycaemia disrupts retinal glucose handling and redox homeostasis, with particular emphasis on glycogen m...

Retinal degeneration (RD) ultimately leads to blindness owing to progressive photoreceptor loss. Previous studies have shown that microglia play a key role in photoreceptor degeneration through multiple phenotypes. However, the determinants of their phenotypic regulation remain unclear. As microglia migrate into the su...

This review synthesize current advances in lactate signaling and lactylation in the retina, and examines how their dysregulation contributes to neovascularization, inflammation, and neurodegeneration in disorders including diabetic retinopathy, age-related macular degeneration, autoimmune uveitis and glaucoma.

The vertebrate retina is among the most energy-demanding tissues in the body, with photoreceptors accounting for most of its metabolic activity. The photoreceptor outer segment, devoid of mitochondria, carries out visual transduction. Oxidative phosphorylation in the rod inner segment has been considered the primary so...

The mitochondrial, redox, inflammatory, and neurovascular mechanisms proposed for PBM are examined, and preclinical and clinical evidence across nonexudative AMD, inherited retinal degeneration, diabetic retinal disease, and light-induced damage is discussed.

A microglial immunometabolic trajectory framework is proposed in which metabolic states are viewed as branching and potentially reversible determinants of cellular function rather than fixed stages of a universal disease pathway.
