Summary
Overnight orthokeratology is a significant risk factor for microbial keratitis in children. Common pathogens include Pseudomonas aeruginosa and Acanthamoeba, necessitating careful monitoring and management.
Area of Science:
- Ophthalmology
- Microbiology
- Corneal Disease
Background:
- Overnight orthokeratology is a vision correction method using specialized contact lenses.
- Microbial keratitis is a serious eye infection that can lead to vision loss.
Purpose of the Study:
- To detail the clinical presentation, microbiology, and outcomes of microbial keratitis linked to overnight orthokeratology.
- To identify risk factors and common pathogens associated with this condition.
Main Methods:
- Retrospective review of medical records from National Taiwan University Hospital (August 2000 - October 2001).
- Analysis of clinical data, microbiological findings (smears and cultures), and treatment responses.
- Evaluation of visual acuity and complications post-treatment.
Main Results:
- Nine patients (10 eyes) aged 8-17 years were studied.
- Common pathogens identified included Pseudomonas aeruginosa and Acanthamoeba.
- All patients were treated successfully with antimicrobial medications, though four eyes had persistent visual impairment.
Conclusions:
- Overnight orthokeratology is a notable risk factor for microbial keratitis, particularly in pediatric populations.
- Pseudomonas aeruginosa and Acanthamoeba are key causative agents.
- The risk of microbial keratitis associated with orthokeratology requires significant attention.

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...
