Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

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: Treatment01:27

Open Angle Glaucoma: Treatment

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...

Summary

Descemet

Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Transplantation Biology

Background:

  • Corneal endothelial dysfunction necessitates transplantation.
  • Descemet's stripping endothelial keratoplasty (DSEK) is a standard treatment.
  • Penetrating keratoplasty (PK) is largely superseded by endothelial keratoplasty (EK).

Purpose of the Study:

  • To review the evolution of endothelial keratoplasty (EK) techniques.
  • To compare clinical outcomes of newer EK methods with DSEK.
  • To assess the long-term survival of EK compared to PK.

Main Methods:

  • Review of current literature on endothelial keratoplasty.
  • Analysis of clinical outcomes and visual rehabilitation data.
  • Examination of endothelial cell survival and refractive predictability.

Main Results:

  • Descemet's membrane endothelial keratoplasty (DMEK) and automated DMEK show improved visual outcomes over DSEK.
  • Endothelial keratoplasty (EK) demonstrates comparable 5-year survival rates to penetrating keratoplasty (PK).
  • Newer EK techniques offer significant visual benefits.

Conclusions:

  • Endothelial keratoplasty (EK) techniques are advancing, offering superior visual outcomes.
  • Further research is needed to optimize visual results, refractive accuracy, and cell survival in EK.
  • Continued refinement of donor preparation and insertion techniques is essential for EK success.
