Angle Closure Glaucoma: Treatment

708
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

Phacoemulsification with a capsular tension ring (CTR) is safer for dislocated lenses than fragmatome techniques. This approach reduced complications like retinal detachment and cortical remnants, improving visual outcomes.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Lens Management

Background:

  • Zonular insufficiency presents a surgical challenge during lens removal.
  • Managing dislocated lenses requires specialized techniques to ensure favorable outcomes.

Purpose of the Study:

  • To compare the surgical outcomes of two distinct techniques for managing dislocated lenses.
  • Evaluate the safety and efficacy of phacoemulsification with capsular tension ring (CTR) assistance versus ultrasonic fragmatome-assisted lens removal.

Main Methods:

  • A comparative study involving 64 eyes with complete or near-complete zonular loss.
  • Group 1: Phacoemulsification with temporary CTR, followed by anterior vitrectomy (AV) or pars plana vitrectomy (PPV).
  • Group 2: Ultrasonic fragmatome-assisted lens removal with perfluorocarbon liquid (PFCL) support and PPV. All eyes received intrascleral intraocular lens (IOL) fixation.

Main Results:

  • Both techniques significantly improved best-corrected visual acuity.
  • Phacoemulsification with CTR showed a lower incidence of cystoid macular edema (5.9% vs. 23.3%) and retinal detachment (0% vs. 10%).
  • Group 2 experienced more cortical remnants (10% vs. 0%) and transient intraocular pressure elevation.

Conclusions:

  • Phacoemulsification with temporary CTR assistance is a safer surgical approach for dislocated lenses.
  • This technique offers a reduced complication profile compared to fragmatome-assisted methods.
  • Effective management of zonular insufficiency can be achieved with careful technique selection.
