Treat the individual and not the angle.

Area of Science:

• Ophthalmology
• Glaucoma Research
• Surgical Interventions

Background:

• Primary angle closure glaucoma (PACG) is a vision-threatening condition, often more severe than primary open-angle glaucoma (POAG).
• Primary angle closure (PAC) spectrum includes primary angle closure suspect (PACS), PAC, and PACG, with PACS posing diagnostic and therapeutic challenges.
• The inconspicuous nature of PACS complicates timely intervention.

Purpose of the Study:

• To evaluate the optimal indications for laser peripheral iridotomy (LPI).
• To clarify the role of LPI in managing different stages of primary angle closure.
• To provide guidance on LPI application in both therapeutic and prophylactic contexts.

Main Methods:

• Review of clinical trials and existing literature on laser peripheral iridotomy.
• Analysis of indications, contraindications, and side effects of LPI.
• Discussion of LPI's efficacy in acute PACG versus its prophylactic use in PACS.

Main Results:

• Laser peripheral iridotomy is established as the gold standard treatment for acute PACG.
• Evidence regarding the prophylactic use of LPI in PACS remains debated.
• LPI application necessitates a personalized, case-by-case approach.

Conclusions:

• Laser peripheral iridotomy is a crucial intervention for acute primary angle closure glaucoma.
• The prophylactic use of LPI for primary angle closure suspect requires individualized assessment.
• A thorough understanding of LPI's benefits and risks is essential for optimal patient management.
