Summary
Regenerative medicine offers new hope for dry eye disease (DED) by moving beyond palliative treatments. Research focuses on restoring the lacrimal functional unit for long-term tear film homeostasis.
Area of Science:
- Ophthalmology
- Regenerative Medicine
- Biotechnology
Background:
- Dry eye disease (DED) affects the ocular surface due to lacrimal functional unit dysfunction.
- Current DED treatments are palliative, necessitating research into regenerative strategies.
- Restoring tear film homeostasis is crucial for ocular health.
Purpose of the Study:
- To review current treatments and limitations for DED.
- To analyze experimental regenerative approaches for tear film disorders.
- To highlight advances in lacrimal gland regeneration.
Main Methods:
- Selective literature review of 127 publications up to January 2026.
- Focus on experimental and translational approaches for tear film homeostasis.
- Inclusion of recent studies on lacrimal gland regeneration.
Main Results:
- Overview of diseases altering tear film composition.
- Analysis of current treatment limitations.
- Exploration of regenerative strategies: stem cells, tissue engineering, gene therapy, biomaterials.
Conclusions:
- Regenerative approaches shift DED management from symptomatic to restorative.
- Stem cells, biomaterials, and tissue engineering offer promising therapeutic foundations.
- Further research and translational studies are needed for clinical applications.
