AIM: To analyze the postoperative infection of pathological myopia with pocket scleral reinforcement. ·METHODS:The clinical data of 167 cases of pathological myopia treated with pocket scleral reinforcement in June to December 2014 were analyzed. The postoperative infection rate, the resistance of pathogenic bacteria were analyzed, and the related factors of infection were analyzed. ·RESULTS: A total of 286 eyes were obtained in 167 patients. The infection rate was 6. 3% in 10 patients ( 18 eyes) . There were 30 pathogenic bacteria isolated from the 18 infected eyes, in which were 10 Staphylococcus aureus, 10 Staphylococcus epidermidis, 6 Klebsiella pneumoniae, 4 Pseudomonas aeruginosa infection. Gram positive bacteria showed higher resistance to penicillin, ampicillin and ciprofloxacin, and were sensitive to vancomycin. The resistance rates of gram negative bacteria to cefotaxime were higher, but to imipenem was low. The two groups of patients age, culture level, operation time, the number of operation, intraoperative nursing staff seniority, postoperative medication compliance rate was statistically significant (P<0. 05), which related to the infection after pocket scleral reinforcement. ·CONCLUSION:The infection caused by Staphylococcus aureus is the most common after pocket scleral reinforcement, and it is sensitive to vancomycin, and gram negative bacteria is sensitive to imipenem. Shortening the operation time, using the experienced nursing staff to cooperate, reducing the number of operation and improving the compliance of the patients can reduce the postoperative infection.
