| Abstract | ||
| • Vernal keratoconjunctivitis (VKC) is a chronic allergic disease with seasonal recurrence of ocular surface inflammation characterized by intense itching, tearing, photophobia, and mucous discharge, associated with conjunctival hyperemia and chemosis • Corneal involvement in VKC patients occurs in the form of superficial punctate keratitis, with superficial pannus, pseudogerontoxon, shield ulcer, astigmatism and keratoconus. • Children with VKC have a high incidence of keratoconus and astigmatism and have more abnormal corneal topography patterns compared with normal eyes. • VKC is an important cause of hospital referral among children in many parts of Africa, Asia, and the Middle East with a prevalence of 5% reported for children in their first decade in Chad and Djibouti. The pathogenesis of VKC is complex and involves Aim of the work: • Evaluate Scheimpflug image changes occurring in cornea in patients with vernal keratoconjunctivitis. Patients: • Prospective cross-sectional study carried out on 75 patients with vernal keratoconjunctivitis (VKC) and 75 normal subjects matched with age and sex. | ||
