Abstract
Autoimmune Retinopathy (AIR) may affect circadian rhythms and sexual function through immune-mediated damage to specific retinal cells.
- Circulating autoantibodies in AIR target retinal antigens, leading to retinal degeneration.
- Retinal ganglion cells, including melanopsin-expressing intrinsically photosensitive retinal ganglion cells (ipRGCs), may be involved in broader retinal dysfunction in AIR.
- ipRGCs are crucial for regulating circadian rhythms and neuroendocrine functions.
- Dysfunction in the ipRGC pathway has been linked to conditions like glaucoma and diabetic retinopathy, which share mechanisms with AIR.
- Disruption of circadian rhythms could influence testosterone secretion, melatonin production, and nitric oxide signaling, potentially contributing to erectile dysfunction.
