Successfully Improving Visual Acuity in Keratitis-Ichthyosis-Deafness Syndrome Utilizing Gas-Permeable Lenses: A Case Report

There is currently no well-defined guideline for treatment and management of patients with keratitis-ichthyosis-deafness (KID) syndrome, and most patients will face disabling vision loss due to corneal neovascularization and cicatrization. We offer this case as an example of how we can improve visual acuity (VA) and quality of life even in advanced cases of corneal neovascularization. We showcase the use of gas-permeable (GP) contact lenses to provide useful, functional VA in a patient with long-standing visual impairment secondary to corneal neovascularization and irregularity due to KID syndrome. The patient's VA improved from 20/200 both eyes (OU) to 20/40 OU with successful fitting of GP lenses, which additionally relieved the patient's otherwise intractable monocular diplopia.
