Swabs of the anterior eye segment of 180 eyes (145 patients) taken in
the time period between August 1, 1989 until August 30, 1989 were sent
to an external, independent microbiological institute in order to ver
ify in-vitro antibacterial properties of marketed sulfacetamide contai
ning drugs. MIC test was performed with isolated pathogenic bacterial
strains without knowledge of the underlying diagnosis. It was shown th
at sulfacetamide is able to inhibit the growth of all isolated strains
. Depending on the type of bacteria concentrations of 0.006 up to 6.4%
sodium sulfacetamide proved to be effective. Simultaneously, all pati
ents were treated with sulfacetamide containing ointment and/or eye dr
ops 4 times daily for maximum of 14 days. With swabs taken at interval
s of 7 and 14 days no bacterial growth was detected.
