| Abstract |
PURPOSE
Keratitis-ichthyosis-deafness (KID) syndrome is a congenital ectodermal disorder presenting the triad of vascularizing keratitis, erythrokeratoderma, and sensorineural deafness. Ocular manifestations such as hyperkeratinization of the eyelids, loss of eyelashes, keratoconjunctivitis sicca, corneal erosions, ulceration, neovascularization, and scarring opacity may be absent or mild, but if present and severe, they can lead to major visual loss. We report a patient with KID syndrome with severe ocular manifestations and the histologic characteristics of a corneal lesion. CASE SUMMARY: A 5-year-old boy was referred to the Ophthalmology Department for bilateral hyperkeratinization of eyelids, bare eyelashes, and corneal opacity. He showed hyperkeratotic skin lesions and sensorineural hearing loss. Molecular analysis showed a mutation in the GJB2 gene and confirmed the diagnosis of KID syndrome. Initial conservative treatment did not preserve ocular surface integrity, and instead it was maintained by surgical procedures including superficial lamellar keratectomy with amniotic membrane transplantation. The histologic characteristics of corneal lesions are abnormal epithelial differentiation, absence of connexin 26 expression, and partial destruction of the basement membrane. |
