Quantitative corneal neural imaging using in vivo confocal microscopy in cases of congenital corneal anesthesia: A prospective analysis and clinical correlation

Waardenburg syndrome-associated neurotrophic keratopathy in a child treated with neurotization surgery

Waardenburg syndrome (WS) is a congenital developmental disorder characterized by congenital sensorineural hearing loss and pigmentary deficiencies in the iris, hair, and skin. Ocular associations of WS include choroidal and iris hypopigmentation and foveal hypoplasia. Possible associations include cataracts and retinal vein occlusion. We report the first case of neurotrophic cornea and relate our experience with neurotization surgery.

Lacrimal Gland Hypoplasia and Corneal Anesthesia in MIRAGE Syndrome: A Case Report and Literature Review

PURPOSE

The purpose of this report was to describe the ocular findings in Myelodysplasia, Infection, Restriction of growth, Adrenal hypoplasia, Genital problems, and Enteropathy (MIRAGE) syndrome, a multisystem congenital disorder.

METHODS

This was a case report and literature review.

RESULTS

An infant with MIRAGE syndrome (combined immunodeficiency with recurrent infections, growth restriction, adrenal insufficiency, 46,XY karyotype with hypovirilization, dysphagia, gastroesophageal reflux disease, and dysautonomia) underwent ophthalmological evaluation because of persistent conjunctivitis during his 8-month admission in the neonatal intensive care unit. His parents noted absence of tears when crying since birth. Bilateral broad corneal epithelial defects were noted, and treatment was initiated with frequent lubricating ointment. At 9 months, his vision was estimated at 20/380 in both eyes using Teller Acuity Cards. There were persistent bilateral epithelial defects, confluent punctate epithelial erosions, low Schirmer strip wetting (right eye 3 mm and left eye 2 mm), and decreased corneal sensation. Brain magnetic resonance imaging images demonstrated hypoplastic lacrimal glands bilaterally. More aggressive lubrication and installation of punctal plugs in all 4 lids were successful at preventing further epithelial defects.

CONCLUSIONS

This case presents deficient lacrimation as a manifestation of MIRAGE syndrome and is the first to identify lacrimal gland hypoplasia and corneal anesthesia. Autonomic and neurologic dysfunction have been proposed to play a role in the pathophysiology of hypolacrimation in similar syndromes and likely contributed to the poor ocular surface in this case. Patients with MIRAGE should undergo ophthalmic assessment as soon as possible after birth because early intervention is essential to preventing irreversible corneal damage.
