Angle Closure Glaucoma: Treatment

Angle 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...

Glaucoma: Overview

Glaucoma: 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...

Open Angle Glaucoma: Treatment

Open 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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Microbiome of the Eye

Microbiome 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...

Summary

Infectious keratitis caused by Staphylococcus aureus can occur after deep sclerectomy, a glaucoma surgery. Prompt antibiotic treatment resolved the infection, but left a corneal scar, highlighting a potential early complication.

Area of Science:

Ophthalmology
Microbiology

Background:

Nonpenetrating glaucoma surgery, such as deep sclerectomy with a collagen implant, aims to reduce intraocular pressure.
Postoperative complications require careful monitoring and prompt management.

Observation:

A 68-year-old woman developed infectious keratitis two weeks after uneventful deep sclerectomy in her left eye.
Corneal scraping identified Staphylococcus aureus as the causative agent.

Findings:

The patient received topical antibiotic treatment for the bacterial keratitis.
The corneal infiltration resolved completely following treatment, resulting in a corneal scar.

Implications:

Bacterial keratitis is a potential early complication following nonpenetrating glaucoma surgery.
This case underscores the importance of considering infectious keratitis in the differential diagnosis of postoperative ocular inflammation.
