LONG AXIAL LENGTH IS A RISK FACTOR FOR INFECTIOUS ENDOPHTHALMITIS IN MICROINCISIONAL VITRECTOMY AND MEMBRANE PEELING...

Area of Science:

• Ophthalmology
• Retinal Surgery
• Infectious Diseases

Background:

• Infectious endophthalmitis (IE) is a serious complication following intraocular surgery.
• Micro-incision vitrectomy surgery with membrane peeling (MIVS-MP) is a common procedure for epiretinal membranes (ERM).
• Identifying risk factors for IE after MIVS-MP is crucial for prevention and management.

Purpose of the Study:

• To investigate the incidence and risk factors associated with infectious endophthalmitis (IE) after micro-incision vitrectomy surgery and membrane peeling (MIVS-MP).

Main Methods:

• A retrospective review of medical records of patients undergoing MIVS-MP for epiretinal membranes (ERM).
• Analysis of IE incidence, causative microorganisms, and potential risk factors including age, gender, simultaneous cataract surgery, axial length, refractive error, intraocular pressure (IOP), myopic tractional maculopathy (MTM), and diabetes mellitus (DM).

Main Results:

• The incidence of IE was 0.45% (16 out of 3,496 eyes).
• Common causative organisms included Staphylococcus epidermidis.
• Increased IE risk was observed in females, eyes with MTM (5.0%), and high myopia (1.7%). Eyes with MTM and high myopia showed significantly lower early postoperative IOP.
• No significant difference in IE rates was found for age, axial length, simultaneous cataract surgery, or diabetes mellitus.

Conclusions:

• High myopia and myopic tractional maculopathy (MTM) are significant risk factors for postoperative infectious endophthalmitis (IE) following micro-incision vitrectomy surgery and membrane peeling (MIVS-MP).
• Lower early postoperative intraocular pressure (IOP) in eyes with high myopia and MTM may contribute to increased susceptibility to IE.
