  • Clinical analysis of 282 patients with infectious endophthalmitis

    Objective To analyze the causes and pathogens of infectious endophthalmitis in our hospital. Methods The clinical data and laboratory findings of 282 inpatients with infectious endophthalmitis were retrospectively reviewed. There were 206 males(73.05%)and 76 females(26.95%)with a mean age of (36.0plusmn;11.2) years (range from 2 to 79 years). Except 14 patients who lost their eyeballs as of serious conditions, pathogen examinations of vitreous specimen had been performed for all remaining 268 cases. The clinical and laboratory data were statistically analyzed by Chi-square and Kappa consistency tests, when P<0.05 the difference should be considered as statistically significant. Results The 4 major causes of infectious endophthalmitis of those 282 patients included ocular trauma (177 cases, 62.77%), infectious keratitis (61 cases, 21.63%), eye surgery (32 cases, 11.35%), and endogenous endophthalmitis (12 cases, 4.25%). 19.21% of the patients in ocular trauma group was 2-13 years old, 55.74% of the patients in infectious keratitis group was 14 -50 years old, and 60.61% of the patients in eye surgery group was 51-79 years old. The major pathogens were fungus and staphylococci each accounted for 30.63% of all cases. Most of the pathogenic bacteria were sensitive to ciprofloxacin (81.81%) and gentamicin (77.92%). Conclusions The major reason of infectious endophthalmitis was ocular trauma, and the major pathogens were fungus and staphylococci. Those findings may help us to treat infectious endophthalmitis patients appropriately.

  • 感染性眼内炎研究现状及进展

    感染性眼内炎是由各种病原体进入眼内导致的 眼内感染和炎症反应,视感染源的不同分为外源性和内源性眼内炎。外源性眼内炎多由外伤 和眼内手术引起,其致病菌分别以混合感染和革兰阳性菌为主;内源性眼内炎主要是由身体其他部位感染延移引起,致病菌以真菌感染为主。眼内液的微生物检查是确诊眼内炎的 可靠方法,聚合酶链式反应在证实病源微生物感染方面有较高阳性率。及时有效的药物是成 功治疗眼内炎的关键,玻璃体视网膜手术是治疗严重眼内炎的有效手段。

  • Analysis of pathogenic factors and etiological characteristics of 531 patients with suppurative endophthalmitis

    ObjectiveTo analyze pathogenic factors and etiological characteristics of suppurative endophthalmitis.MethodsA total of 531 consecutive patients (531 eyes) with suppurative endophthalmitis who were hospitalized in Qingdao Eye Hospital of Shandong Eye Institute from January 2006 to December 2015 were included in the study. Among them, 410 patients with 410 eyes were males (77.2%), 121 patients with 121 eyes were females (22.8%). The average age of the patients was 38.62±15.36 years. The relevant medical records were collected to analyze the pathogenic factors. Samples of aqueous humor, vitreous or other intraocular samples were taken under aseptic conditions for bacterial and fungal culture and in vitro drug sensitivity test.ResultsOcular trauma was the primary pathogenic factor of suppurative endophthalmitis (60.1%), other factors included postoperative endophthalmitis (19.0%), suppurative keratitis-related endophthalmitis (17.1%) and endogenous endophthalmitis (3.8%). Postoperative endophthalmitis mainly occured after cataract surgery. A total of 224 strains of organisms were isolated, among which the predominant organisms isolated were gram-positive bacteria (54.0%) and staphylococcus epidermidis was the most common (25.0%). The other pathogenic organisms were fungi (29.5%) and gram-negative bacteria (16.5%). Among the fungi, aspergillus (10.7%) was the dominant genus, followed by fusarium (9.8%). For gram-positive organisms, susceptibilities were vancomycin 97.4%, gatifloxacin 91.8%, fusidate acid 77.9% and levofloxacin 54.6%. For gram-negative organisms, susceptibilities were gatifloxacin 85.7%, levofloxacin 77.8%, tobramycin 71.4% and ceftazidime 62.5%. For fungal isolates, sensitivities were voriconazole 88.2% and amphotericin B 84.8%.ConclusionsOcular trauma is the main pathogenic factor of suppurative endophthalmitis, followed by postoperative endophthalmitis and suppurative keratitis-related endophthalmitis. Gram-positive bacteria are the major pathogenic organisms, especially staphylococcus epidermidis followed by fungal species, among which aspergillus and fusarium were the dominating pathogenic genus.
