Chronic closed-angle glaucoma is often missed, leading to severe vision loss. Early diagnosis with gonioscopy and ultrasound biomicroscopy, followed by iridotomy, is crucial for managing this condition.

Area of Science:

  • Ophthalmology
  • Glaucoma Research

Background:

  • Chronic closed-angle glaucoma (CCG) is significantly more prevalent than the acute form.
  • CCG frequently remains undiagnosed for extended periods, leading to substantial visual field deficits and potential eye loss.

Purpose of the Study:

  • To highlight the diagnostic challenges of chronic closed-angle glaucoma.
  • To emphasize the importance of specific diagnostic tools and treatment for CCG.

Main Methods:

  • Diagnosis relies on gonioscopy to identify characteristic features.
  • Ultrasound biomicroscopy (UBM) is employed when gonioscopy results are inconclusive, detecting conditions like goniosynechiae, ciliary body/lens malposition, or iridociliary cysts.

Main Results:

  • Pupillary block is the initiating factor in most CCG cases (approximately 90%).

  • Iridotomy is the recommended intervention for pupillary block, though it may not be a complete solution on its own.

    • Conclusions:

    • Accurate diagnosis of CCG requires specialized techniques like gonioscopy and UBM.
    • Prompt intervention, including iridotomy, is essential for managing CCG and preventing irreversible vision damage.
