Congenital Insensitivity to Pain: A Case Report With Corneal Esthesiometry and In Vivo Confocal Microscopy.

Cornea - 1 Dec 2021

Keenan Jeremy D, Gonzales John A, Waxman Stephen G, Delwig Anton

Abstract excerpt

PURPOSE: To report the findings of a comprehensive eye examination from an individual with congenital insensitivity to pain because of loss-of-function mutations in the SCN9A gene. METHODS: Ophthalmologic examination and confocal microscopy were performed on a patient with congenital insensitivity to pain. RESULTS: A 39-year-old man with compound heterozygous mutations in the SCN9A gene underwent examination....
