Argon laser application to the angle structures in the glaucomas

U Ticho, H Zauberman

    Archives of Ophthalmology (Chicago, Ill. : 1960)
    |January 1, 1976
    PubMed
    Summary

    Argon laser treatment for glaucoma initially lowers eye pressure by increasing outflow facility. However, this effect is often temporary, with pressure returning in most cases as laser-induced openings in angle structures close during healing.

    Area of Science:

    • Ophthalmology
    • Laser Surgery

    Background:

    • Glaucoma is a leading cause of irreversible blindness.
    • Effective control of intraocular pressure (IOP) is crucial in glaucoma management.
    • Argon laser therapy is a potential treatment modality for certain types of glaucoma.

    Observation:

    • Twenty eyes with uncontrolled glaucoma were treated with argon laser beams targeting angle structures.
    • An initial decrease in IOP was observed in nineteen eyes post-treatment.
    • Outflow facility (C values) increased during the hypotensive period.

    Findings:

    • In 15 eyes, elevated IOP recurred within 20 to 40 days.
    • Four eyes maintained reduced IOP for ten months, including cases of congenital glaucoma, post-filtering surgery glaucoma, and aphakic eyes.
    • Reduced C values correlated with IOP increase, suggesting closure of laser-induced openings.

    Implications:

    • Argon laser treatment can induce temporary hypotony and improve outflow facility by creating openings in angle structures.
    • The long-term efficacy depends on the patency of these laser-induced openings.
    • Further surgical intervention was required in six cases due to treatment failure.
