Effectivity of Nd Yag PI in treatment of acute primary angle closure glaucoma

Area of Science:

• Ophthalmology
• Glaucoma Research
• Surgical Efficacy Studies

Background:

• Acute primary angle closure glaucoma (AACG) is a serious condition requiring prompt treatment.
• Nd Yag Peripheral Iridotomy (PI) is a common intervention for AACG.
• Understanding the efficacy of PI in diverse patient populations is crucial for clinical practice.

Purpose of the Study:

• To evaluate the efficacy of Nd Yag Peripheral Iridotomy (PI) in treating acute primary angle closure glaucoma (AACG).
• To identify factors associated with successful PI treatment and treatment failure in AACG patients.

Main Methods:

• A prospective hospital-based study conducted in Nepal Eye Hospital.
• Included 50 patients diagnosed with acute primary angle closure glaucoma (AACG).
• Excluded patients with secondary angle closure glaucoma.

Main Results:

• 78% of eyes achieved controlled intraocular pressure (IOP) after Nd Yag PI.
• Mean visual acuity improved from presenting levels (e.g., 1/60-PL) to 6/60 at discharge.
• Mean IOP decreased significantly to 12 mmHg post-procedure.
• Factors like prolonged attack duration, elderly age, and very high presenting IOP were linked to PI failure.

Conclusions:

• Nd Yag Peripheral Iridotomy (PI) is an effective treatment for a majority of acute primary angle closure glaucoma (AACG) cases.
• Early intervention and appropriate patient selection are key to successful PI outcomes.
• Further research may explore management strategies for cases with risk factors for PI failure.
