👁 “Microbiologic Diagnosis of Bacterial Keratitis – From Scraping to Staining”While clinical features can suggest a probable pathogen,the definitive diagnosis of bacterial keratitis requires microbiologic confirmation viacorneal scraping, staining, and culture to guide antibiotic choice and ensure appropriate management.🔍 Diagnostic Steps for Microbial KeratitisStepDescriptionClinical suspicio..

..Nontuberculous Mycobacterium (NTM) is a rare but critical pathogen in post-surgical infectious keratitis, especially after refractive surgeries like LASIK. Due to its slow growth and deep stromal localization, early detection is difficult and misdiagnosis as non-infectious DLK or viral keratitis is common.🔹 Microbial Profile & PathogenesisNTM refers to all mycobacteria excluding M. tuberculos..

👁 “Uncommon Bacterial Keratitis – Clues to Rare Organisms”While most corneal ulcers are caused by common bacteria like Staphylococcus or Pseudomonas,rare pathogens like Clostridium, Bacillus, Nocardia, and Azotobacter may cause highly specific forms of keratitis,often requiring tailored management due to their distinctive clinical signatures.🦠 Summary Table of Rare Bacterial KeratitisPathogenC..

This post explores less common but clinically relevant bacteria that can cause microbial keratitis. These include Moraxella, Corynebacterium diphtheriae, and Haemophilus influenzae. Though less frequent than Staphylococcus or Pseudomonas, they present unique challenges in diagnosis and management.🔹 Moraxella spp.Risk Factors: Diabetes, alcoholism, systemic illness, autoimmune diseasesClinical S..

👁 “Gonococcal Keratitis – A Rapidly Destructive Corneal Infection”Neisseria gonorrhoeae, a well-known cause of sexually transmitted infections (STIs),can cause severe purulent conjunctivitis that, if untreated, may rapidly evolve into ulcerative keratitis and corneal perforation.🦠 Summary Table of Gonococcal Eye InfectionCategoryDetailsClinical Presentation🔹 Suppurative conjunctivitis🔹 Corne..

Pseudomonas aeruginosa is the most common Gram-negative pathogen responsible for infectious keratitis, especially in contact lens wearers and immunocompromised patients.Its rapid progression and necrotizing purulent infiltration make early diagnosis and aggressive treatment essential.🔹 Clinical Features & ProgressionRapidly progressing stromal melting, with purulent dischargeMay result in ring-..

👁 “Streptococcal Keratitis – From Ulcer Serpens to Crystalline Keratopathy”Streptococcus species, particularly S. pneumoniae and S. viridans,are known to cause distinctive forms of bacterial keratitis, includingthe classic serpiginous ulcers and the more indolent infectious crystalline keratopathy (ICK).🦠 Summary Table of Streptococcal KeratitisOrganismClinical FeaturesS. pneumoniae – Starts a..

Staphylococcus species are the most common causative bacteria of microbial keratitis in South Korea. This article reviews the classification, clinical manifestations, prognosis, and rising antibiotic resistance among staphylococcal infections.🔹 Key Clinical InsightsClassificationCoagulase-positive: Staphylococcus aureusCoagulase-negative: Staphylococcus epidermidis, othersS. aureus KeratitisRis..

👁 “Bacterial Keratitis – A Sight-Threatening Ocular Emergency”Bacterial keratitis is a sight-threatening corneal infection, particularly concerning in contact lens users or those with prior ocular trauma or surgery.Modern antibiotics have reduced systemic infections, but corneal ulcers remain a major cause of irreversible vision loss.🧠 Risk Factors for Bacterial KeratitisCategoryRisk DetailsTr..
