Angle Closure Glaucoma: Treatment

436
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

391
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

507
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
This summary is machine-generated.

Minimally invasive glaucoma surgery, including iStent inject and Hydrus Microshunt, effectively lowers intraocular pressure and reduces medication needs. Further trials are required to confirm the efficacy of other novel glaucoma procedures.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Glaucoma Management

Background:

  • Glaucoma affects 1.4% of Germans aged 35-74, a leading cause of blindness.
  • Lowering intraocular pressure is the only evidence-based treatment for glaucoma.
  • Minimally invasive glaucoma surgery offers a safer alternative to traditional methods.

Purpose of the Study:

  • To review current evidence on minimally invasive glaucoma surgical procedures.
  • To evaluate the efficacy and safety of novel intraocular pressure-lowering techniques.
  • To compare outcomes of different glaucoma surgical interventions.

Main Methods:

  • Selective review of PubMed publications.
  • Inclusion of randomized controlled trials and meta-analyses.
  • Analysis of studies on specific minimally invasive glaucoma surgeries.

Main Results:

  • Trabeculectomy is the standard but has 3-15% complication rates.
  • Minimally invasive glaucoma surgery with stents shows a better safety profile for mild/moderate glaucoma.
  • iStent inject and Hydrus Microshunt demonstrated significant intraocular pressure reduction and slowed visual field defects.

Conclusions:

  • iStent inject and Hydrus Microshunt are effective in lowering intraocular pressure and decreasing reliance on eyedrops.
  • High-quality controlled trials are necessary to validate other minimally invasive glaucoma procedures.
  • Minimally invasive glaucoma surgery presents a promising, safer approach for managing glaucoma.
