Abstract Details


We present the largest reported series of children Corneal anesthesia (CA) in childhood carries a poor prognosis and there is little literature on its management with this rare disorder.


Magrabi Hospital Aseer King Saudia Arabia


We performed a retrospective chart review of children with congenital or acquired CA presenting to our institution over the last 15 years. Patients with concurrent facial nerve or other cranial nerve palsies were included.


21 eyes of 16 children were identified with CA caused by posterior fossa tumors (5), cerebellar hypoplasia (3), severe head trauma (3), familial dysautonomia (2) and isolated CA (3).The median follow-up 47.5 months. Six eyes in four children had final visual acuities (VA) of 20/40 or better. All eyes with VA 20/200 or worse at last follow-up had associated facial nerve palsy or isolated CA. Complications included corneal scarring (81%), infectious keratitis (48%),corneal neovascularization (48%) and perforation secondary to keratitis (5%). Four children underwent corneal grafting for perforation or scarring. All grafts became opaque,with VAs of 20/800 or worse


Discussion: Isolated CA, and CA with CNVIIP, are associated with visual outcomes below 20/200. Earlier tarsorrhaphy Conclusion: We recommend that ophthalmologists suspect and test for CA in children with painless epithelial defects and consider early tarsorrhaphy may help preserve vision in these high-risk eyes.
