Özet
Purpose. To describe changes in the conjunctival flora due to retrograde flow after conjunctivodacryocystorhinostomy (CDCR) with Jones' tube implantation. Methods. In 20 patients, one year after unilateral CDCR with Jones' tube implantation and a functionally successful outcome, conjunctival and nasal mucosal specimens were taken from the operated side for bacteriological analyses and non-operated eye conjunctival specimens were simultaneously taken as the control group. The samples were cultivated in conventional media and also in hypertonic media in order to isolate L-forms of bacteria and to increase the isolation rate and sensitivity. Results. Bacterial growth was detected in 16 operated (80%) and 11 non-operated eyes (55%) and 26 bacteria were isolated from nasal mucosa in 20 cases (isolation rate 100%). Bacteria isolated from the non-operated specimens were S. epidermidis (63.6%, seven cases), S. aureus (27.2%, three cases) and Corynebacterium sp. (9.0%, one case). Conjunctival cultures of the operated eyes yielded S. epidermidis in three (18.7%), S. aureus in six (37.5%), Corynebacterium sp. in two (12.5%) and other bacteria in five (31.3%). Nasal mucosal cultures contained S. epidermidis in nine cases (45%), S. aureus in eight (40%), Corynebacterium sp. in two (10%) and miscellaneous bacteria in seven cases (35%). Conclusions. After CDCR the conjunctival flora of the eye undergoes differentiation and becomes similar to the nasal flora.
