5 Key Takeaways

• 1

  Primary angle-closure glaucoma is a leading cause of blindness globally, necessitating effective management strategies.

• 2

  Laser peripheral iridotomy (LPI) is favored over observation for high-risk primary angle-closure suspect (PACS) patients.

• 3

  Prophylactic LPI significantly reduces the risk of PACS converting to PAC or PACG, though absolute risk reduction is small.

• 4

  Accurate gonioscopy is crucial for monitoring PACS, but variability in technique can lead to misclassification of patients.

• 5

  Anterior segment optical coherence tomography (AS-OCT) shows promise in assessing PACS, but its predictive power needs further study.
