What this research studies

This project will create new lab models and imaging methods to map the nerves that sense the cornea and control tears and blinking. Scientists will use animal models, cellular techniques, and advanced imaging to trace the circuits from the eye to sensory ganglia and brain regions. They will examine how injury, inflammation, or nerve damage changes signals that protect the ocular surface and cause abnormal sensation or pain. Findings will be linked to human biology where possible to point toward targets for future treatments.

Who could benefit from this research

Good fit: People with dry eye symptoms, reduced tear production, corneal nerve injury, or chronic ocular surface pain would be the most relevant candidates.

Not a fit: Patients whose problems are limited to unrelated eye conditions (for example, isolated retinal disease or cataract without ocular surface issues) are unlikely to benefit directly.

Why it matters

Potential benefit: If successful, this work could point to new targets or tests that reduce chronic eye pain and improve tear film and ocular surface health.

How similar studies have performed: Past research has linked corneal nerve damage to dry eye and ocular pain, but the integrated tools and models proposed here are relatively new and less tested in patients.
