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...

A new computer-guided laser treatment, patterned laser trabeculoplasty, significantly reduced intraocular pressure in open-angle glaucoma patients. This minimally invasive procedure showed a 24% decrease in eye pressure over six months.

Area of Science:

  • Ophthalmology
  • Medical Technology

Background:

  • Open-angle glaucoma is a leading cause of irreversible blindness.
  • Current treatments aim to lower intraocular pressure (IOP).

Purpose of the Study:

  • To describe a novel computer-guided laser treatment for open-angle glaucoma: patterned laser trabeculoplasty (PLT).
  • To present the preliminary clinical evaluation of PLT's efficacy and safety.

Main Methods:

  • Forty-seven eyes with open-angle glaucoma underwent PLT using a 532-nm laser with 100-μm spots.
  • Treatment involved sub-visible, 5-ms pulses with power titrated for trabecular meshwork blanching.
  • Computer-guided automatic rotation of 66-spot arc patterns covered 360° of the trabecular meshwork.

Main Results:

  • An average of 1,100 laser spots were applied per eye.
  • Intraocular pressure decreased from 21.9 ± 4.1 mm Hg pre-treatment to 16.0 ± 2.3 mm Hg at 1 month (n=41).
  • IOP remained stable around 15.5 ± 2.7 mm Hg during 6 months of follow-up (n=30).

Conclusions:

  • Patterned laser trabeculoplasty offers a rapid, precise, and minimally traumatic treatment option.
  • The computer-guided approach ensures exact pattern abutment.
  • PLT demonstrated a significant 24% reduction in intraocular pressure over 6 months (P < .01).
