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...

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

This summary is machine-generated.

The iStent trabecular micro-bypass system safely and effectively lowers intraocular pressure (IOP) in glaucoma patients. This minimally invasive glaucoma surgery reduces or eliminates the need for glaucoma medications.

Keywords:

Intraocular pressure glaucoma iStent

Area of Science:

Ophthalmology
Medical Devices
Glaucoma Treatment

Background:

Current glaucoma therapies have limitations.
The iStent trabecular micro-bypass system offers a novel surgical approach.
It targets the trabecular meshwork, a primary site of resistance to aqueous humor outflow.

Purpose of the Study:

To review the safety and efficacy of the iStent trabecular micro-bypass system.
To assess its role in managing open-angle glaucoma (OAG) and refractory glaucoma.

Main Methods:

A literature search was conducted using terms like "trabecular micro-bypass stent."
Relevant published articles and abstracts were included.
Exclusion of duplicated published articles.

Main Results:

Clinical trials demonstrate the iStent's safety and efficacy in reducing intraocular pressure (IOP).
The iStent effectively lowers IOP compared to traditional treatments.
It reduces or eliminates the need for ocular antihypertensive drugs.

Conclusions:

The iStent trabecular micro-bypass system is a safe and effective treatment for glaucoma.
It is particularly beneficial for OAG patients undergoing combined cataract surgery.
It offers a valuable option for patients with glaucoma refractory to conventional therapies.
