Summary
Pre-operative conjunctival bacterial colonization increases endophthalmitis risk. Prophylactic screening via conjunctival smears before intraocular surgery can help reduce the risk of post-operative infections.
Area of Science:
- Ophthalmology
- Microbiology
Context:
- Postoperative endophthalmitis is a serious complication following intraocular surgery.
- Bacterial colonization of the conjunctiva is a known risk factor for endophthalmitis.
Purpose:
- To evaluate persistent or transient microbial colonization of the conjunctiva before intraocular surgery.
- To assess the relationship between conjunctival colonization and the risk of endophthalmitis.
Summary:
- Conjunctival smears were performed on 481 patients before intraocular surgery.
- A significant bacterial growth was found in 129 patients (26.8%).
- Of those with positive initial smears, 30% showed persistent colonization, while 70% had transient colonization.
Impact:
- Persistent microbial colonization of the conjunctiva may be a significant factor in developing postoperative endophthalmitis.
- Recommends prophylactic conjunctival smears before surgery to mitigate the risk of intraocular infections.
