Summary
Pseudomonas luteola, a gram-negative bacterium, can cause chronic postoperative endophthalmitis after cataract surgery. Prompt treatment with antibiotics led to significant visual recovery in this case report.
Area of Science:
- Ophthalmology
- Microbiology
Background:
- Chronic postoperative endophthalmitis presents a diagnostic and therapeutic challenge.
- Cataract surgery is a common predisposing factor for endophthalmitis.
Observation:
- A 61-year-old patient developed progressive vision loss, hypopyon, and vitritis post-cataract surgery.
- Diagnostic vitrectomy and intraocular lens explantation were performed for analysis.
- Aerobic cultures identified Pseudomonas luteola in vitreous samples and on the explanted lens.
Findings:
- Pseudomonas luteola was identified as the causative agent of chronic endophthalmitis.
- The patient showed improvement with intravitreal piperacillin/tazobactam and oral trimethoprim/sulfamethoxazole.
- Best-corrected visual acuity improved from hand motions to 20/40.
Implications:
- Pseudomonas luteola may be a less virulent cause of chronic endophthalmitis.
- Effective management with targeted antibiotic therapy can lead to favorable visual outcomes.
- This case highlights the importance of microbiological diagnosis in persistent postoperative endophthalmitis.

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
