Summary
This review examines the degeneration of retinal ganglion cells (RGCs) in diabetic retinopathy, noting that neuronal damage precedes vascular changes and results in irreversible visual deficits. For lighting designers and healthcare practitioners, the progressive loss of RGCs—which include melanopsin-containing ipRGCs critical for circadian photoentrainment—highlights the importance of early intervention and adapted lighting strategies for diabetic patients.
Key Findings
- Retinal neuron impairment, including RGC degeneration, occurs before detectable vascular changes in diabetic retinopathy, making it an early biomarker of disease progression.
- RGC axons have minimal intrinsic regenerative capacity after injury, rendering visual functional deficits clinically irreversible without intervention.
- Significant progress over the past two decades in animal models has demonstrated potential for RGC axon regeneration, offering hope for future neural repair strategies in diabetic retinopathy.
