Open Angle Glaucoma: Treatment

958
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: 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...

Summary
This summary is machine-generated.

Posterior capsular opacification (PCO) risk may be reduced with anteriorly fixated intraocular lenses (IOLs). Capsulotomy-fixated IOLs showed lower PCO rates compared to in-the-bag IOLs in a systematic review.

Area of Science:

  • Ophthalmology
  • Biomaterials Science

Background:

  • Posterior capsular opacification (PCO) is the most frequent complication after cataract surgery.
  • Understanding factors influencing PCO is crucial for improving long-term visual outcomes.

Purpose of the Study:

  • To investigate if intraocular lens (IOL) fixation type impacts PCO risk.
  • To compare neodymium-doped YAG (Nd:YAG) capsulotomy rates between capsulotomy-fixated (FEMTIS) and in-the-bag IOLs.

Main Methods:

  • A systematic review of eligible studies was performed.
  • Studies reporting quantitative Nd:YAG capsulotomy rates at a minimum of 3 months post-implantation were included.

Main Results:

  • Capsulotomy-fixated IOLs (FEMTIS) exhibited lower Nd:YAG capsulotomy rates (3.1% at 12 months).
  • In-the-bag IOLs (LENTIS) showed higher capsulotomy rates (4.7% at 12 months).
  • Comparison was made between IOLs with identical material and edge profiles.

Conclusions:

  • Anterior fixation of IOLs may reduce PCO by enhancing capsule-optic contact and limiting cell migration.
  • Early evidence suggests anterior fixation as a strategy to improve long-term capsular clarity.
  • Further prospective studies are needed due to limitations in current data heterogeneity and follow-up duration.
