Changing patterns in treatment of angle closure glaucoma.

Area of Science:

• Ophthalmology
• Glaucoma Research
• Surgical Innovation

Background:

• Angle closure glaucoma is a significant global cause of blindness.
• Evolving treatment strategies necessitate a review of current interventions.
• Anterior segment imaging enhances understanding and measurement of treatment efficacy.

Purpose of the Study:

• To review recent literature on laser and surgical interventions for primary angle closure disease.
• To evaluate the effectiveness of current treatment modalities.
• To provide evidence-based recommendations for managing angle closure glaucoma.

Main Methods:

• Review of recent scientific literature on angle closure glaucoma treatments.
• Analysis of studies evaluating laser peripheral iridotomy (LPI) and argon laser peripheral iridoplasty (ALPI).
• Comparison of outcomes between clear lens extraction and LPI in specific patient cohorts.

Main Results:

• Laser peripheral iridotomy (LPI) provides temporary angle widening, with effects diminishing over time.
• Argon laser peripheral iridoplasty (ALPI) has not demonstrated substantial clinical benefit.
• Clear lens extraction shows superior clinical and quality of life outcomes compared to LPI in patients with early/moderate PACG or PAC with high IOP.

Conclusions:

• Recent evidence supports clear lens extraction as an initial treatment for PACG or primary angle closure with IOP > 30 mmHg.
• LPI efficacy is limited in the long term for primary angle closure suspects.
• Further research may be needed to optimize management strategies for angle closure disease.
