Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

899
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

771
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...

Area of Science:

  • Ophthalmology
  • Medical Technology

Background:

  • Glaucoma is a leading cause of blindness globally, managed primarily by lowering intraocular pressure (IOP).
  • Selective laser trabeculoplasty (SLT) emerged in 2001 as a significant advancement in glaucoma treatment.
  • SLT offers advantages over argon laser trabeculoplasty (ALT) due to lower energy use, reduced inflammation, and minimal trabecular meshwork injury.

Purpose of the Study:

  • To review the current literature on Selective Laser Trabeculoplasty (SLT) for glaucoma management.
  • To consolidate evidence on SLT's efficacy, safety, and repeatability.

Main Methods:

  • Literature review of studies on Selective Laser Trabeculoplasty (SLT).
  • Analysis of data comparing SLT with Argon Laser Trabeculoplasty (ALT) and topical medications.
  • Evaluation of SLT's effectiveness in lowering intraocular pressure (IOP).

Main Results:

  • SLT is demonstrated to be as effective as ALT and topical medications in reducing IOP.
  • SLT utilizes significantly less laser energy compared to ALT.
  • SLT procedures result in less anterior segment inflammation and mechanical damage to the trabecular meshwork.

Conclusions:

  • Selective Laser Trabeculoplasty (SLT) is a well-established, effective, and repeatable treatment for lowering intraocular pressure (IOP) in glaucoma patients.
  • SLT represents an improvement over older laser trabeculoplasty methods due to its safety and efficacy profile.
  • The review supports SLT as a key component in modern glaucoma management strategies.
