Summary
This review examines how inherited retinal dystrophies cause progressive photoreceptor loss through oxidative stress, neuroinflammation, and tissue remodeling, with light-induced stress being a contributing vulnerability factor. For lighting design, this underscores the importance of managing light exposure intensity and spectrum to minimize oxidative and phototoxic stress in individuals with compromised retinal homeostasis.
Key Findings
- Inherited retinal dystrophies share common pathophysiological features including cell death, inflammation, and oxidative/nitrosative stress despite diverse genetic mutations.
- High energy demands, continuous oxygen exposure, and light-induced stress make retinal cells particularly vulnerable to homeostatic disruption.
- Microglial activation and gliosis trigger pro-inflammatory cytokine and chemokine secretion, exacerbating photoreceptor degeneration.
- Following photoreceptor loss, surviving retinal neurons undergo synaptic rewiring and complete morphological remodeling of retinal tissue.
