Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.5K
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...

Glaucoma: Overview01:25

Glaucoma: Overview

1.6K
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...

Suctioning the Nasopharyngeal Airway

4.3K
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Summary

The new irrigation-hydro (iH) technique for cataract surgery uses phaco tip vacuum to create dynamic pressure for hydrodissection. This method avoids high intraocular pressure, preventing complications like capsular block syndrome.

Area of Science:

  • Ophthalmology
  • Surgical Techniques

Background:

  • Manual hydrodissection in cataract surgery can lead to high intraocular pressure (IOP).
  • High IOP during hydrodissection may cause complications such as capsular block syndrome and anterior hyaloid membrane tears.

Purpose of the Study:

  • To evaluate the safety and efficacy of the irrigation dynamic pressure-assisted hydrodissection technique (irrigation-hydro [iH]).
  • To determine if the iH technique can reduce IOP and prevent hydrodissection-related complications during cataract surgery.

Main Methods:

  • The iH technique utilizes the phaco tip to create dynamic irrigation pressure for cortical-capsular cleavage.
  • This method eliminates the need for manual hydrodissection with a syringe and cannula.
  • Intraocular pressure is managed by limiting bottle height, reducing hydrostatic pressure.

Main Results:

  • The iH technique was successfully used in 607 out of 609 cataract surgeries.
  • No significant complications related to high-pressure hydrodissection were observed.
  • The technique effectively achieved cortical-capsular cleavage during phacoemulsification.

Conclusions:

  • The irrigation-hydro (iH) technique is a safe and effective alternative for hydrodissection in cataract surgery.
  • This method helps prevent complications associated with high intraocular pressure during the procedure.
  • The iH technique offers significant benefits for patient safety by mitigating risks like capsular block syndrome.
