ABSTRACT

Objective To investigate the clinical treatment of nonpenetrated cornea trauma caused by crops. Methods Clinical data of 128 cases of nonpenetrated cornea trauma caused by crops were retrospectively analyzed. According to the interval time between occurrence of trauma and clinic visiting, the patients were divided into 3 groupsgroup A (33 cases,<24 h), group B (72 cases, 24 h≤interval time<1 week) and group C (23 cases, ≥ 1 week). The therapeutic effects and prognosis were analyzed. Results There was statistical difference in the incidence of corneal ulcer among group A, group B and group C 6.1% (2/33), 62.5% (45/72) and 100.0% (23/23), χ2= 52.32, P<0.01. In group B, 12 cases were treated with conjunctival flap covering, 2 cases received keratoplasty and 2 cases undertook enucleation. In group C, 10 cases were treated with conjunctival flap covering, 4 cases received keratoplasty and 2 patients undertook enucleation finally. All the other patients were cured with local debridement and medical treatment. Conclusions Patients with nonpenetrated cornea trauma caused by crops may develop infectious keratitis, and prompt and proper treatment can avoid the secondary infection and improve the outcome. Local debridement in combination with iodophors disinfection can prevent the incidence of infectious keratitis. Conjunctival flap covering is an effective technique in the treatment of corneal ulcer caused by nonpenetrated cornea trauma.
