Angle Closure Glaucoma: Treatment

1.1K
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

912
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
  • Surgical Innovation
  • Pharmacology

Background:

  • Traditional cataract surgery prophylaxis relied on patient-administered topical eye drops.
  • Patient adherence and correct instillation technique can be challenging with topical drops.
  • Topical drop use can lead to issues like corneal toxicity and inconsistent dosing.

Purpose of the Study:

  • To review the evolving landscape of prophylaxis for adverse events after cataract surgery.
  • To highlight the shift from topical eye drops to surgeon-administered intraoperative injections.
  • To assess the benefits of assured drug delivery for optimizing healing and reducing complications.

Main Methods:

  • Review of current trends and emerging techniques in cataract surgery prophylaxis.
  • Analysis of the advantages of intraoperative drug delivery methods.
  • Discussion of the development of periocular corticosteroid injection techniques.

Main Results:

  • Increasing adoption of intracameral antibiotic injections by European and American surgeons.
  • Development of periocular corticosteroid injection techniques for inflammation prophylaxis.
  • Potential to achieve a "drop-free" cataract surgery experience when combined with intraoperative pharmacologic dilation.

Conclusions:

  • Intraoperative injections provide reliable drug delivery for both patients and surgeons.
  • This approach circumvents problems associated with patient adherence and topical drop instillation.
  • Intraoperative injections promise improved outcomes and reduced adverse events compared to traditional methods.
