Abstract

Purpose To describe a Japanese patient with lattice corneal dystrophy type I (LCD I) who lacked the typical lattice lines. Design Interventional case report. Methods A complete ophthalmologic examination was performed on a 54-year-old woman, and the TGFBI gene was analyzed by direct genomic sequencing. Results The patient had diffuse opacification of the central corneal stroma but without lattice lines and corneal epithelial erosions bilaterally. Molecular genetic analysis identified a lattice corneal dystrophy I-associated heterozygous missense alteration (C417T) that changed arginine in codon 124 to cysteine (R124C) in the TGFBI gene. Conclusions The cornea of the patient appeared to represent late-stage lattice corneal dystrophy I, which suggests the existence of interactions of modifier genes, environmental factors during corneal aging, or both. The molecular genetic analysis of TGFBI can offer rapid, accurate diagnosis of patients with atypical corneal appearance.
