“…In our area we found that patients older than 64 years had more conjunctival flora and more bacteria density than those younger than 65 years, in a sample of 794 patients awaiting cataract extraction (panel communication to the National Congress of the Ophthalmology Spanish Society, Sevilla, 1992); this result disagrees with those found before 1975, 3,4 but agrees with two others obtained a few years later, 5,6 although patients in these studies did not undergo cataract surgery.…”

Aim To ascertain the effect of elderly in the conjunctival bacteria frequency of patients undergoing cataract extraction. Methods A retrospective case series study of 4432 consecutive patients who underwent cataract surgery, without excluding any of them for having pre-existing diseases. Their preoperative conjunctival culture were performed over a 3-year period (1994)(1995)(1996). Bacteria were grouped in nine categories and patients were divided into seven groups, according to age; comparisons between groups were made by means of the v 2 test, and the Mantel-Haenszel test to analyse age as a confounder, using SPSS program, version 12. Results Patients aged over 74 years accounted for 41.4%; women predominated among this group (61.4%), but not in the patients younger than 75 (47.7%); In the whole sample women accounted for 53.4%. Patients aged 75-96 years had a greater frequency of: Corynebacteria, Staphylococcus aureus, Streptococcus sp. (except Streptococcus pneumoniae), Gram-negative cocci and Gramnegative rods (except Haemophilus sp.) and 'other bacteria' categories than those aged 3-74 years. Different bacteria frequency in both sexes produced a confounding effect in the comparison between age-groups. Men had more Staphylococci coagulase (-), S. pneumoniae and Gram-negative rods than women. Conclusions Elderly patients awaiting cataract surgery had more conjunctival bacteria than those younger than 75 years, except Staphylococcus coagulase negative, S. pneumoniae and Haemophilus sp. At any age, men had more bacteria than women. These increments of frequencies could increase the risk of intraocular surgery contamination.

“…Staphylococcus epidermidis accounts for 57-87% of isolates (Cason and Winkler, 1954;Fahmy et al, 1974;Seal et al, 1982;Thiel and Schumacher, 1994), while Streptococcus species accounts for only 6% of all aerobic cultures (Thiel and Schumacher, 1994). Gram-negative bacteria have been shown to be present in 0-5% of aerobic isolates in normal conjunctival flora (Cason and Winkler, 1954;Fahmy et al, 1974;Seal et al, 1982;Thiel and Schumacher, 1994).…”

This study demonstrates a significant change in bacterial flora and antibiotic treatment requirements of purulent dacryocystitis from previously published data. A higher incidence of Gram-negative organisms, particularly Pseudomonas, with resistance to commonly used antibiotics was found. The emergence of rarer highly resistant Gram-negative microorganisms may also indicate a trend in lacrimal sac infections. These findings suggest that the antibiotic treatment protocol before and after lacrimal surgery should be reconsidered in this subgroup of patients.

“…Staphylococcus epidermidis accounts for between 57 and 87% of isolates [7][8][9][10], while Streptococcus species accounts for only 6% of all aerobic cultures [7]. Gram-negative bacteria have been shown to be present in 0-5% of aerobic isolates of normal conjunctival flora [7][8][9][10]. Anaerobic flora are found to be present in up to 77% of normal eyes [11][12][13].…”

This study demonstrates a significant change in bacterial flora and antibiotic treatment requirements of purulent dacryocystitis from previously published data. A higher incidence of Gram-negative organisms, particularly Pseudomonas, with resistance to commonly used antibiotics was found. The emergence of rarer, highly resistant, Gram-negative microorganisms may also indicate a trend in lacrimal sac infections. These findings suggest that the antibiotic treatment protocol before and after lacrimal surgery should be reconsidered in this subgroup of patients.
