The cornea is innervated by the trigeminal nerve. I just saw a patient whose headaches, and tinnitus started after a cornea burn. TMJ symptoms also were exacerbated. I looked for previous cases but did not come across any.
Pubmed had an abstract that showed that experimental burns to cornea of mice created brain inflamation at the trigeminal ganglia.

The patient I am seeing was burned by a new powerful LED Flashlght . Interesting, I have seen these flashlights advertised on the internet for protection.
Are they dangerous? Could they burn corneas or cause chronic pain syndromes?
I am interested in talking to patients whose problems began with a cornea burn tear or abrasion as a possible cause of brain inflamation of the trigeminal ganglia.
