Spectrum: Neurotrophic Keratitis to Neuropathic Pain

When dry eyes turn into chronic eye pain, it may no longer be just a tear problem. Severe dry eye can evolve into neuropathic eye pain and neurotrophic keratitis due to corneal nerve damage and trigeminal nerve dysfunction.

Why do some people have intense eye pain with a normal exam, while others have corneal damage but feel nothing?

Dr. Joseph Allen is joined by cornea specialist Dr. Laura Periman and neuro-optometrist Dr. Jacqueline Theis to break down the science behind chronic ocular pain.

In This Episode You Will Learn

✅ Why dry eye can become chronic eye pain

✅ The role of inflammation in corneal nerve damage

✅ How neuropathic eye pain develops

✅ What neurotrophic keratitis really means

✅ Why anti-inflammatory treatment alone may not work

✅ How concussion and brain injury affect dry eye symptoms

✅ The connection between TMJ, neck tension, and eye pain

✅ Why chronic ocular pain needs emotional and sleep support
