Open Angle Glaucoma: Treatment

432
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:

  • Nanomedicine
  • Biocatalysis
  • Ocular Therapeutics

Background:

  • Nanozymes possess nanoscale properties and enzyme-like catalytic activities.
  • They exhibit therapeutic effects including anti-oxidative, anti-inflammatory, anti-microbial, and anti-angiogenic actions.
  • These characteristics are valuable for nanomedicine, especially in ocular therapy, avoiding systemic delivery.

Purpose of the Study:

  • To explore ocular diseases linked to oxidation and inflammation.
  • To highlight the role of nanozymes in managing these conditions.
  • To discuss advanced nanozyme applications and soft material integration in ocular therapeutics.

Main Methods:

  • Review of existing literature on nanozymes in ocular diseases.
  • Analysis of nanozyme properties relevant to ocular barriers.
  • Examination of studies on nanozyme integration with soft materials.

Main Results:

  • Nanozymes show potential in treating multi-factorial ocular diseases like dry eye and age-related macular degeneration.
  • Their small size and modifiability facilitate ocular barrier penetration for targeted or prolonged therapy.
  • Integration with soft materials enhances their application in ocular disease management.

Conclusions:

  • Nanozymes represent a promising therapeutic strategy for ocular diseases driven by oxidation and inflammation.
  • Further research is needed to translate nanozyme advancements into clinical applications for eye conditions.
  • Future investigations should focus on bridging the gap between nanozyme research and practical ocular therapeutics.
