Summary
This study details a rare case of acute postoperative endophthalmitis caused by vancomycin-resistant Staphylococcus hominis. Prompt treatment involving vitrectomy and silicone oil tamponade was necessary.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Acute postoperative endophthalmitis is a severe intraocular infection following eye surgery.
- Phacoemulsification with intraocular lens implantation is a common cataract surgery procedure.
Observation:
- An 80-year-old male developed acute endophthalmitis 2 days post-surgery.
- Clinical signs included decreased visual acuity, conjunctival injection, corneal edema, and hypopyon.
- B-scan ultrasonography revealed vitreous opacification.
Findings:
- Vitreous culture identified vancomycin-resistant Staphylococcus hominis.
- The isolate was resistant to multiple common antibiotics including fluoroquinolones and vancomycin.
- The organism remained sensitive to trimethoprim/sulfamethoxazole and teicoplanin.
Implications:
- This case highlights the emerging challenge of antibiotic-resistant bacteria in postoperative endophthalmitis.
- Management required aggressive surgical intervention and targeted antibiotic therapy.
- Visual outcomes remain a concern even with treatment for resistant strains.

01:22Microbiome of the Eye
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
01:25Glaucoma: 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...
01:28Angle 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...
