Area of Science:

  • Ophthalmology
  • Glaucoma Research
  • Laser Therapy

Context:

  • Primary angle-closure glaucoma (PACG) is a condition characterized by a narrow or closed anterior chamber angle.
  • Peripheral iridotomy is a common surgical intervention for PACG.
  • Evaluating the efficacy of domestic YAG laser systems is crucial for accessible treatment.

Purpose:

  • To assess the effectiveness and safety of the domestic JYZ-1 Model YAG laser microruptor for performing peripheral iridotomy in patients with primary angle-closure glaucoma.

Summary:

  • Peripheral iridotomy was performed on 56 eyes with primary angle-closure glaucoma using the JYZ-1 YAG laser.
  • The procedure demonstrated a 100% success rate, with an average of 5 laser shots and 212 mJ energy.
  • Postoperative follow-up (3.57 months) showed a mean intraocular pressure (IOP) reduction of 2.43 mmHg, decreased medication use, and improved chamber angle status.

Impact:

  • The JYZ-1 YAG laser is a viable and effective tool for peripheral iridotomy in primary angle-closure glaucoma.
  • Successful treatment can lead to reduced medication dependence and improved long-term visual outcomes.
  • The study highlights the potential for domestic laser technology to provide safe and effective glaucoma management.
