AIM: To study the clinical curative effect of corneal ulcer debridement combined with conjunctiva flap covering surgery in treatment of fungal corneal ulcer. METHODS: From January 2011 to November 2011,30 cases (30 eyes) with fungal corneal ulcer were treated with removal of the necrotic corneal tissue combined with conjunctiva flap covering surgery. RESULTS: Postoperatively, the corneal ulcer in 17 cases(17 eyes) was cured after one surgery, and whose conjunctiva flaps were good; the corneal ulcer in 7 cases (7 eyes) was cured by drug in 10 days-2 months after one surgery, and whose conjunctiva flaps were desquamated in 1 week; the corneal ulcer in 2 cases(2 eyes) was cured after treated again by conjunctiva flap covering surgery after the conjunctiva flap was desquamated in 1 week; the corneal ulcer in 4 eyes was not cured after one surgery whose conjunctiva flaps were desquamated in 1 week, because of corneal perforation, they had to be performed by keratoplasty. 26 cases (26 eyes) were cured by conjunctiva flap covering surgery in 30 cases (30 eyes), the total effective rate was 87%.  CONCLUSION: Corneal ulcer debridement combined with conjunctiva flap covering surgery is a kind of effective and practical method in treatment of fungal corneal ulcer. It can be applied in primary hospital, and it is an effective method to control the fungus inflammation and save the eyeballs and remnant vision, which provide the further condition for corneal transplantation.
