RESUMO
Objective:To detect the chlamydia psittaci DNA in patients with ocular adnexal lymphomas,and find out the relationship between chlamydia psittaci infection and ocular adnexal lymphomas.Methods:Tissue samples from 36 patients with ocular adnexal lymphomas were collected,as well as samples from patients with benign lymph disease and patients with eye trauma as controls.Chlamydia psittaci DNA were detected by PCR.Results:The chlamydia psittaci DNA positive rates in patients with ocular adnexal lymphomas,benign lymph diseases and ocular trauma organizations were 47.2%,5.0%,0.0%(?2 = 24.578,P=0.000 1),respectively.The DNA positive rates in patients withⅠ A period were 52.0%,36.4% of Ⅱ A period(?2 =0.749,P=0.387).5,8-year survival rates of all the cases were 90.1%,78.5%,which were the same in Chlamydia psittaci DNA positive group and negative group(?2 = 0.163,P= 0.687).Conclusion:The incidence of ocular adnexal lymphomas may be related with Chlamydia psittaci infection.But there is no evidence of the relationship with Chlamydia psittaci infection and of the ocular adnexal lymphomas stage and prognosis.
