    Summary

    Continuous wave argon laser iridectomy effectively treated glaucoma in most patients. This outpatient procedure offers a promising alternative to surgical iridectomy, though long-term results are pending.

    Area of Science:

    • Ophthalmology
    • Laser Surgery
    • Glaucoma Treatment

    Background:

    • Angle-closure glaucoma is a condition requiring intervention to relieve intraocular pressure.
    • Surgical iridectomy has been a traditional treatment, but carries surgical risks.
    • Laser-based alternatives are being explored for less invasive glaucoma management.

    Purpose of the Study:

    • To evaluate the efficacy and safety of continuous wave argon laser iridectomy.
    • To assess its viability as an alternative to traditional surgical iridectomy for angle-closure glaucoma.

    Main Methods:

    • Continuous wave argon laser was used in a multiburn fashion for iridectomies.
    • The procedure was performed on an outpatient basis under topical anesthesia.
    • Success was defined by achieving patent iridectomies.

    Main Results:

    • Successful iridectomies were achieved in 42 out of 45 phakic eyes.
    • Five procedures required multiple sittings or site changes for patency.
    • Ten eyes needed retreatment for pigment proliferation post-procedure.
    • The procedure was generally quick (<30 minutes) with minimal complications.

    Conclusions:

    • Continuous wave argon laser iridectomy is a viable alternative to surgical iridectomy for angle-closure glaucoma.
    • The outpatient laser procedure demonstrates a favorable safety profile.
    • Long-term efficacy data for this laser modality is not yet available.
