In recent years, corneal neuralgia in dry eye patients has received more and more clinical attention.Corneal neuralgia refers to the increasing pain of cornea in response to normal painless stimuli, which has a serious negative effect on patients’ work and daily life.Corneal neuralgia is often one of the common symptoms of dry eye.Dry eye can also cause corneal sensation decline and the mechanism is still unclear.Patients with dry eye often exhibit structural and functional changes in ocular surface nerve, so understanding the mechanism of dry eye-related neurological abnormalities will help to treat and prevent dry eye-related neurological abnormalities.Various factors such as instability of tear film, abnormal tear secretion, ocular surface inflammation, and increased osmotic pressure of tear film may be involved in dry eye-associated corneal neuralgia.Clinically, anti-inflammatory therapy, lubricating ocular surface, promoting regeneration of corneal nerve fibers, analgesic therapy targeting receptors, palpebral edge treatment, and systemic intervention if necessary are mainly performed based on the pathogenesis of dry eye related corneal neuralgia.In this article, the pathologic and influencing factors of corneal neuralgia were summarized, and the pathogenesis of dry eye-related corneal neuralgia were investigated to help the clinical diagnosis and treatment of dry eye-related corneal neuralgia.
