To evaluate corneal biomechanical changes in patients with vernal keratoconjunctivitis (VKC).
University of Messina, Italy
In this cross-sectional study, patients with a diagnosis of VKC were enrolled. Additionally, healthy subjects matched for age and sex, were included as controls. All patients underwent a complete ocular examination, including evaluations of clinical manifestations of VKC, itching and eye rubbing frequency were assessed using a visual analogue scale, conjunctival hyperemia was graded using bulbar redness score using Keratograph 5M detecting the blood vessels in the conjunctiva and automatically evaluating the degree of redness, corneal tomography by Pentacam HR, and corneal biomechanics by Corvis ST.
Belin/Ambrosio enhanced ectasia total deviation index (BAD-D) was significantly higher in the VKC group than in the non-allergic conjunctivitis patients (p < 0.05). The tomography and biomechanical index (TBI) was also significantly higher in the VKC group (p < 0.05).
Patients with vernal keratoconjunctivitis present corneal biomechanical changes that could increase the risk of keratoconus and corneal ectasia.
