[Incidence of postoperative bacterial infections after planned intraocular interventions].

Between August 1982 and August 1984 3059 intraocular operations were performed with topical prophylactic antibiotics. Results of conjunctival cultures did not influence the surgical schedule. 8179 intraocular operations were performed between September 1984 and August 1988. An intraocular operation was postponed until conjunctival cultures were negative using topical antibiotics administered at hourly intervals. The rate of postoperative intraocular infections decreased significantly (p less than 0.0001) from 21 (0.69%) of 3059 during the first to 9 (0.11%) of 8179 intraocular operations during the second observation period. In the first period 11 vitrectomies and 2 enucleations due to bacterial endophthalmitis had to be performed. In the second period 2 vitrectomies and no enucleations were necessary (p less than 0.0001). Our results indicate, that decontamination of the conjunctiva may be an import factor for the prevention of postoperative endophthalmitis following elective intraocular surgery.

[Persistence and transient conjunctival pathogen colonization before planned intraocular interventions].

The risk of a postoperative endophthalmitis is influenced by the presence of a significant bacterial colonisation of the conjunctiva before intraocular surgery. Between February and August 1990 we performed conjunctival smears in 481 patients 1) on the eve of the operation and 2) just before planned intraocular surgery, to evaluate a persistent or transient microbial colonisation of the conjunctiva. 352 patients showed insignificant ("negative") and 129 patients a significant ("positive") bacterial growth in the first conjunctival smear. 96% of the patients (n = 336) had a negative result in both smears. 30% of the patients (n = 37) with a positive conjunctival smear showed a persisting bacterial colonisation, whereas 70% of the patients (n = 92) had a transient colonisation of the conjunctiva with a negative second smear. As a persisting microbial colonisation of the conjunctiva may be an important factor for the development of postoperative endophthalmitis, we recommend prophylactic conjunctival smears before surgery to diminish the risk of intraocular infections after surgery.

[Bacterial pathogen and resistance spectrum of the non-irritated conjunctiva. 7,845 preoperative smears at the ophthalmologic clinic of the Erlangen university].

The type and extent of bacterial colonization of the conjunctiva at the time of an intraocular operation may have a major influence on the risk of post-operative endophthalmitis. Between March 1986 and December 1988 a total of 7845 preoperative conjunctival smears were therefore examined by culture of Erlangen University Eye Hospital, in cooperation with the Department of Clinical Microbiology. Altogether, 1221 (15.6%) of the smears were classified as positive. Surgery on the patients concerned was postponed and gentamicin eye drops were administered for decontamination of their conjunctivae until the smears were negative. From the positive smears 1393 strains were cultured, identified, and submitted to a resistance test. The present paper reports the frequency distribution of the species of bacteria isolated and their resistance behavior, and compares the results with those of other authors. The value of preoperative cultures in the prevention of postoperative endophthalmitis and the importance of resistance tests in the context of topical application of antibiotics are discussed.

[Listeria monocytogenes kerato-uveitis].

An 86-year-old patient with corneal gutae and diabetes presented with a Listeria monocytogenes serpent ulcer on her right eye. Smears taken from the ulcer revealed Listeria monocytogenes serotype 4b. Despite specific antibiotic therapy including cephalosporins and systemic administration of amikacin, as well as topical gentamycin drops, the eye had to be enucleated on the 16th day after hospitalization. Massive fibrinous reaction and extreme pain causing the patient to reject alimentation were the clinical signs at this time. The anterior chamber aspirate taken perioperatively was sterile.
