Endophthalmitis: an investigational process

Area of Science:

• Ophthalmology
• Surgical Infections
• Microbiology

Background:

• Endophthalmitis is a serious intraocular infection that can lead to vision loss.
• Cataract surgery is a common procedure with a low but significant risk of endophthalmitis.
• The patient's endogenous microflora, particularly skin flora, is increasingly recognized as a potential source of post-operative ocular infections.

Purpose of the Study:

• To investigate the role of the operating room environment and patient's skin flora in the development of endophthalmitis following cataract surgery.
• To identify the primary microbial sources contributing to post-operative endophthalmitis.

Main Methods:

• Review of clinical cases of endophthalmitis occurring after cataract surgery.
• Analysis of microbial cultures from ocular samples and relevant environmental/skin sites.
• Correlation of identified pathogens with pre-operative and intra-operative factors.

Main Results:

• Patient's own skin flora was identified as a significant source of causative organisms in post-cataract surgery endophthalmitis.
• Specific bacterial species commonly found on skin were frequently isolated from infected eyes.

Conclusions:

• Pre-operative skin preparation and intra-operative aseptic techniques are critical to minimize the risk of endophthalmitis.
• Targeting patient's skin flora is essential in strategies to prevent endophthalmitis after cataract surgery.
