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...

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...

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...

Summary

This summary is machine-generated.

Contact lens wear can lead to fungal keratitis, a serious eye infection. Early pathogen identification is crucial for effective treatment and preventing vision loss from corneal ulcers.

Area of Science:

Ophthalmology
Medical Mycology

Background:

Contact lens-associated keratitis (CLAK) poses a significant risk for corneal ulceration.
Empirical anti-infective and anti-inflammatory treatments are often initiated before pathogen identification.

Observation:

A 43-year-old female contact lens wearer presented with a 2-month history of left eye keratitis and corneal ulceration.
Initial empirical therapy yielded no improvement.

Findings:

Corneal scrapings and contact lens solution cultures identified filamentous fungi, specifically Acremonium sp.
Despite prompt, targeted antifungal therapy, a keratoplasty (corneal transplant) was required.

Implications:

This case highlights the importance of early and accurate pathogen identification in managing CLAK.
Prompt diagnosis and specific treatment are essential to prevent severe outcomes like corneal perforation and vision loss.
Standard procedures including corneal debridement and culturing are vital for successful CLAK management.
