• 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:
