A Case of Shield Ulcer Due to Vernal Keratoconjunctivitis


Corneal shield ulcer is an uncommon but serious complication of vernal keratoconjunctivitis (VKC) that can threaten visual acuity. We present a 12-year-old case with a corneal shield ulcer on the superior part of the cornea in the right eye. We learned from his history that he was treated with topical cyclosporine A (CsA) and corneal debridement was performed for the same complaints six months ago. His complaints recurred six months after ceasing topical CsA voluntarily. Topical anti-allergic and CsA treatments were commenced, we also performed corneal debridement. During his follow-ups, the corneal ulcer healed leaving a scar as opacity and neovascularization. This case highlights the role of the anti-inflammatory effect of CsA in preventing the recurrence of shield ulcers.
