Abstract

Insights

A rare case of post-traumatic endophthalmitis caused by Bacillus pumilus/safensis occurred after a sheep farm injury. Prompt treatment improved vision, highlighting the importance of identifying unusual pathogens in eye infections.

Area of Science:

  • Ophthalmology
  • Microbiology
  • Infectious Diseases

Background:

  • Post-traumatic endophthalmitis is a severe intraocular infection following eye trauma.
  • Ocular trauma can introduce various microorganisms, including bacteria, into the eye.

Observation:

  • A 62-year-old male sustained a corneal laceration from baling wire on a sheep farm.
  • The patient developed endophthalmitis, with vitreous aspirate identifying Bacillus pumilus or Bacillus safensis.

Findings:

  • Initial management included corneal repair and intravitreal antibiotics.
  • Severe inflammation necessitated pars plana vitrectomy, lensectomy, and fluid-air exchange due to retained lens material and retinal edema.
  • Visual acuity improved from hand motion to 20/60 at three months post-treatment.

Implications:

  • This case highlights Bacillus pumilus/safensis as a potential cause of post-traumatic endophthalmitis.
  • Early diagnosis and aggressive management are crucial for visual recovery in such cases.
  • Awareness of atypical bacterial pathogens in ocular infections is important for ophthalmologists.

Glaucoma: Overview01:25

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...
