Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

623
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

527
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 Techniques

Background:

  • Soft cataracts present surgical challenges due to poor cleavage planes.
  • Conventional phacoemulsification techniques can be difficult with soft cataracts.

Purpose of the Study:

  • To describe a new phacoemulsification technique for soft cataracts.
  • To demonstrate the efficacy of high vacuum and zero energy in managing soft cataracts.

Main Methods:

  • A novel technique involving creating a central groove in sculpting mode.
  • Holding the nucleus with vacuum in chop mode to divide it into pieces.
  • Emulsifying pieces using high vacuum (600 mmHg) without torsional or longitudinal energy.

Main Results:

  • The technique successfully divided and emulsified soft cataractous lens material.
  • High vacuum and zero energy allowed for controlled chopping and emulsification.
  • Utilized a newer generation phaco machine with an active fluidic system.

Conclusions:

  • This high vacuum, zero energy phacoemulsification technique offers a viable solution for soft cataracts.
  • The method allows for effective nuclear division and emulsification, potentially reducing thermal damage.
