Clinical Scorecard: Tips and Tricks for In-Office Laser Peripheral Iridotomy
At a Glance
Category
Detail
Condition
Laser Peripheral Iridotomy
Key Mechanisms
Facilitates aqueous movement from posterior to anterior chamber, reduces pupillary block, relieves angle crowding.
Target Population
Patients with primary angle-closure glaucoma, acute angle-closure attacks, plateau iris configuration, normal and reverse pupillary block, and primary angle-closure suspects.
Care Setting
In-office laser procedures
Key Highlights
Careful patient selection is essential for laser procedures.
Indications for LPI include various forms of angle-closure glaucoma.
Preoperative gonioscopy and antiglaucoma medication are recommended.
Postoperative monitoring includes IOP check and PI examination.
Reported risk of dysphotopsias after treatment is approximately 2% to 3%.
Guideline-Based Recommendations
Diagnosis
Use gonioscopy to assess angle closure.
Measure IOP before and after treatment.
Management
Administer antiglaucoma medication and pilocarpine before treatment.
Use laser energies ranging from 3 mJ to 8 mJ.
Monitoring & Follow-up
Check IOP and PI patency 30 to 60 minutes postoperatively.
Follow up at 1 week for gonioscopy and IOP check.
Risks
Complications may include iris bleeding, cataract progression, and nonpatency of the PI.
Patient & Prescribing Data
Patients undergoing laser peripheral iridotomy for angle-closure glaucoma.
Topical steroid prescribed 2 to 4 times daily postoperatively.
Clinical Best Practices
Obtain written informed consent before procedures.
Use the lowest effective laser energy to minimize complications.
Document blood pressure and pulse prior to treatment.
