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...

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...

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...

Summary

Monitoring end-stage glaucoma requires specific functional assessments, including patient complaints and adapted visual field testing, to detect subtle disease progression. Structural evaluation is less critical at this advanced stage.

Area of Science:

Ophthalmology
Glaucoma Research

Context:

End-stage glaucoma presents significant structural loss and visual function deterioration.
Standard automated perimetry is often inadequate for monitoring patients at this advanced disease stage.

Purpose:

To discuss optimized strategies for monitoring patients with end-stage glaucoma.
To highlight the importance of functional assessment over structural evaluation in advanced glaucoma.

Summary:

Effective monitoring involves intraocular pressure measurement, qualitative structural analysis (e.g., disc photography for hemorrhages), and comprehensive functional assessment.
Patient complaints are crucial; visual acuity testing with trial frames is preferred over phoropters.
Adapted visual field testing, including central 10-degree fields, size V stimuli on a 24-2 grid, and Goldmann perimetry, is essential for detecting progression.

Impact:

Provides guidance for clinicians to improve the management of patients with advanced glaucoma.
Emphasizes the need for tailored functional testing to accurately track disease progression and inform treatment decisions.
