ENDOPHTHALMITIS: IMPROVEMENT OF CULTURE RESULTS

Th. Neß1, K. Pelz2

Infectious endophthalmitis is a rare but serious complication. The identification of the responsible microorganism is important for the prognosis and therapy. In the literature positive cultures were reported in 50 to 75% of cases. The purpose our work was to improve the proportion of positive culture results.

Methods: All necessary materials (culture media: Columbia-, Hämatin-, ENDO- and yeast-cystein-blood-agar, fungus media) and an instruction were allways available in the operation theatre. Thus, culturing of intraocular derived samples could be performed by less experienced residents directly in the operation theatre, especially on duty. On weekends or at night the culture plates were incubated in the department of ophthalmology under optimal conditions and passed to an experienced microbiologist later. Culture results of the first 10 patients suffering from endophthalmitis (acute or chronic postoperativ, endogen) after introduction of these "endophthalmitis-set" were compared to the results of the 11 patients before.

Results: Due to the introduction of the "endophthalmitis-set" the proportion of positive culture results improved from 4/11 to 10/10. The detected microorganisms were all representative of the pathogens commonly causing endophthalmitis (gram-positive bacteria, anaerobic bacteria)

Conclusion: An appropriate culture set always available in the operation theatre may increase the number of positive cultures dramatically and hence help to find the adequate antibiotic treatment in cases of endophthalmitis.
