Endophthalmitis and pars plana vitrectomy

Area of Science:

• Ophthalmology
• Infectious Diseases

Background:

• Endophthalmitis is a serious intraocular infection that can occur after cataract surgery.
• Early diagnosis and treatment are crucial for preserving vision.

Purpose of the Study:

• To review cases of endophthalmitis following cataract extraction.
• To identify factors associated with poor visual outcomes.
• To inform treatment strategies for post-cataract surgery endophthalmitis.

Main Methods:

• Retrospective review of 13 suspected endophthalmitis cases post-cataract extraction (1979-1983).
• Cultures of aqueous and/or vitreous aspirates for bacterial identification.
• Analysis of treatment modalities (antibiotics, vitrectomy) and visual outcomes.

Main Results:

• Seven of 13 cases were confirmed bacterial endophthalmitis.
• Factors linked to poor vision included delayed hospital admission, expulsive hemorrhage, and retinal detachment.
• Gentamicin-resistant Streptococcus viridans led to blindness in two cases.

Conclusions:

• Prompt treatment is essential for bacterial endophthalmitis post-cataract surgery.
• Simultaneous intravitreal injection of two antibiotics is recommended to combat resistant organisms.
• Further research into optimal antibiotic combinations is warranted.
