Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

393
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: Treatment01:28

Angle Closure Glaucoma: Treatment

437
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: Overview01:25

Glaucoma: Overview

508
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...

Direct-Acting Cholinergic Agonists: Therapeutic Uses01:11

Direct-Acting Cholinergic Agonists: Therapeutic Uses

691
Direct-acting cholinergic agonists have many therapeutic uses in various medical fields. Choline esters, including acetylcholine, have limited clinical utility due to their non-selectivity and short duration of action. Still, acetylcholine and carbachol are applied topically during ophthalmologic surgery to induce miosis. Pilocarpine, a muscarinic and ganglionic stimulator, effectively treats open-angle glaucoma and alleviates xerostomia and dry mouth caused by radiotherapy or Sjögren...

  • Ophthalmology
  • Glaucoma Management
  • Ocular Therapeutics

Background:

  • The traditional glaucoma treatment approach prioritizes topical medications.
  • This method faces challenges including poor patient adherence and ocular surface disease.
  • Interventional glaucoma treatments offer alternative strategies.

Purpose of the Study:

  • To review the evolving treatment landscape for glaucoma.
  • To highlight the early use of interventional glaucoma procedures.

  • Review of current literature on glaucoma treatment modalities.
  • Analysis of selective laser trabeculoplasty (SLT), procedural pharmaceuticals, and minimally invasive glaucoma surgeries (MIGS).
  • Discussion of treatment mechanisms including outflow enhancement and aqueous suppression.

Main Results:

  • Emerging data support early adoption of interventional glaucoma treatments.
  • Multiple treatment modalities and mechanisms are often required for adequate IOP reduction.
  • Combining treatments targeting different IOP pathways enhances glaucoma control.

Conclusions:

  • The glaucoma treatment paradigm is evolving towards earlier intervention.
  • A multimodal approach combining medications, laser, and surgery is key for comprehensive IOP control.
  • Targeting multiple IOP reduction mechanisms optimizes glaucoma management.
