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 groups:group 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.

OBJECTIVETo describe the clinical and genetic characteristics of a Chinese family with primary angle-closure glaucoma (PACG).
METHODSLinkage analysis and DNA sequencing as well as single strand conformation polymorphism (SSCP) analysis were performed to identify the disease-causing mutations.
RESULTSThe Arg46Stop mutation in MYOC gene and Leu432Val in CYP1B1 gene were identified in all patients. The digenic alterations have not been identified in any same Chinese control individuals.
CONCLUSIONAuthor identified digenic mutations, Arg46Stop in MYOC gene and Leu432Val in CYP1B1 gene, in a Chinese PACG family. Author's studies suggest a possible role of MYOC and CYP1B1 in the development of PACG and support the hypothesis that PAOG and PACG may have common origin across multiple glaucoma phenotypes.
