Summary
Staphylococcus aureus was the most common cause of bacterial conjunctivitis. Methicillin-resistant S. aureus (MRSA) prevalence significantly increased, alongside rising resistance to common antibiotics like ciprofloxacin.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Bacterial conjunctivitis is a common ocular infection.
- Understanding causative organisms and antibiotic resistance patterns is crucial for effective treatment.
Purpose of the Study:
- To analyze demographic data, common bacterial pathogens, and antimicrobial susceptibility trends in bacterial conjunctivitis cases.
- Focus on a 10-year period (1994-2003) at Bascom Palmer Eye Institute.
Main Methods:
- Retrospective cross-sectional study analyzing microbiology records.
- Included 2408 eyes with bacterial conjunctivitis.
- Data collected on patient demographics, culture results, and in vitro antibiotic susceptibility.
Main Results:
- Staphylococcus aureus was the most frequent pathogen overall and in older children.
- Methicillin-resistant S. aureus (MRSA) prevalence increased significantly from 4.4% to 42.9%.
- Haemophilus influenzae was common in younger children; increased resistance observed for gram-positive bacteria to ciprofloxacin and oxacillin.
Conclusions:
- Staphylococcus aureus remains a primary pathogen in bacterial conjunctivitis.
- The rising prevalence of MRSA and increasing antibiotic resistance necessitate careful treatment selection.
- Gentamicin demonstrated good sensitivity against gram-positive isolates.

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...
01:28Angle 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...
01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
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...
