Evaluation of corneal epithelial thickness mapping using anterior segment OCT in children with vernal keratoconjunctivitis.

VKC is a disease primarily affecting the corneal epithelium. Corneal epithelial thickness mapping may be considered to assess the integrity of the ocular surface in eyes with VKC, and to detect corneal epithelial changes. Disease phenotype may influence the corneal epithelial changes, and the disease duration is another factor influencing these changes.
