A Study on the Effect of Antibiotics on the Normal Flora of the Eye

چکیده
The eye flora was studied in 50 cases hefore and after receiving local antibiotics as a preoperative preparation for ocular surgery. Cultures from inner canthus, upper and lower fomices were done hefore and after receiving antibiotics for 24 hours. Sraph. epidermidis was found lo be the most predominant type of bacteria comprising the eye flora (66%). Comparing hacterial flora in different sites of the eye revealed that the upper fornix is the most sterile site of the eye, while the inner canthus was the least sterile. As a preoperative preparation for ocular surgery, the three antibiotic regimens used succeeded in eradicating or reducing bacterial flora. The most efficient antibiotic regiment used was mephenicol eye drops with polymyxin-B sulphate ointment.
