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...

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...

Summary

Glaucoma surgery aims to lower intraocular pressure. While effective, traditional methods carry risks, prompting research into safer, minimally invasive alternatives like gonioscopic glaucoma surgery.

Area of Science:

Ophthalmology
Surgical Innovation

Context:

Classical filtration surgeries like trabeculectomy are effective for reducing intraocular pressure.
These established procedures, while efficient, present significant risks of intraoperative and interoperative complications.

Purpose:

To explore and develop alternative glaucoma surgical techniques with lower complication rates.
To advance minimally invasive surgical options for managing glaucoma.

Summary:

Non-penetrating glaucoma surgery (NPGS) emerged as a lower-complication alternative to traditional methods.
Ongoing advancements in trabecular meshwork surgery and gonioscopic glaucoma surgery focus on minimizing invasiveness and risk.

Impact:

Facilitates the development of safer surgical options for glaucoma patients.
