Nocardia asteroides keratitis
The British Journal of Ophthalmology
|June 1, 1979
Summary
Nocardia asteroides keratitis is rare, often progressing despite antibiotics. This case highlights the need for prompt diagnosis and tailored treatment, as it presented a severe, non-benign clinical course.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Nocardia asteroides is an uncommon cause of ocular infections, with limited documented cases of keratitis.
- Previous reports suggest nocardial keratitis often follows a relatively benign clinical course.
Observation:
- A case of Nocardia asteroides keratitis is presented, occurring three weeks post-rural trauma.
- The infection progressed rapidly despite initial antibiotic treatment.
Findings:
- The patient's Nocardia asteroides keratitis exhibited a severe, aggressive course, unlike previously reported cases.
- A conjunctival flap was successfully employed seven weeks after the initial injury.
Implications:
- Accurate identification of Nocardia asteroides morphology and antibiotic sensitivity testing are crucial for effective clinical management.
- This case underscores the importance of considering Nocardia species in severe keratitis, especially after trauma, and the potential for aggressive disease progression.

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.

01:28Angle 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...
