Late infections following filtering procedures.

Area of Science:

• Ophthalmology
• Surgical Outcomes
• Infectious Disease

Background:

• Filtering conjunctival blebs are surgical sites prone to infection.
• Late infections can impact visual outcomes in patients with blebs.

Purpose of the Study:

• To determine the incidence and outcomes of late exogenous infections in patients with filtering conjunctival blebs.
• To compare infection rates across different surgical procedures.

Main Methods:

• Retrospective analysis of 364 patients with filtering conjunctival blebs.
• Monitoring for late exogenous infections and their outcomes.
• Comparison of infection rates based on surgical technique, specifically Scheie's procedure.

Main Results:

• The overall incidence of late exogenous infections was determined.
• The Scheie's procedure demonstrated the lowest rate of infection among the studied procedures.
• Visual acuity was preserved in 62.5% of infected cases following treatment.

Conclusions:

• Late exogenous infections of filtering conjunctival blebs are a potential complication.
• The Scheie's procedure may be associated with a reduced risk of such infections.
• Prompt treatment can lead to favorable visual outcomes in many cases of infection.
