Peripheral argon laser iridectomy in narrow-angle glaucoma.

E S Rosen, C L Dodd, R Gupta

    Transactions of the Ophthalmological Societies of the United Kingdom
    |July 1, 1976
    PubMed
    Summary

    Laser peripheral iridectomy shows promise for acute angle-closure glaucoma, particularly in blue irises. However, further improvements are needed for heavily pigmented irises before it can replace surgical treatment.

    Area of Science:

    • Ophthalmology
    • Laser Surgery

    Background:

    • Acute angle-closure glaucoma poses a significant risk to vision.
    • Surgical peripheral iridectomy is the current standard treatment.
    • Laser peripheral iridectomy is explored as a less invasive alternative.

    Purpose of the Study:

    • To evaluate the efficacy of gas argon laser peripheral iridectomy.
    • To assess its suitability as an alternative to surgical iridectomy for acute angle-closure glaucoma.
    • To identify factors influencing success and failure rates.

    Main Methods:

    • Gas argon laser peripheral iridectomy was performed.
    • The procedure was attempted in patients with acute angle-closure glaucoma and for prophylactic treatment in fellow eyes.
    • Success was defined by achieving a permanent red reflex.

    Main Results:

    • Successful outcomes were observed in eyes with blue irises when adequate laser energy was applied.
    • Challenges and reasons for failure in eyes with heavily pigmented irises were noted.
    • The current laser procedure requires significant enhancement.

    Conclusions:

    • Gas argon laser peripheral iridectomy can be effective in specific cases (e.g., blue irises).
    • Further technical advancements are necessary for widespread adoption.
    • Surgical peripheral iridectomy remains the preferred treatment for acute angle-closure glaucoma at present.
