    Summary
    This summary is machine-generated.

    This study evaluated miotic therapy for glaucoma. While pilocarpine and echothiophate iodide showed no significant difference in optic disc or visual field changes compared to control eyes, both can cause cataracts, suggesting conservative use of miotics.

    Area of Science:

    • Ophthalmology
    • Clinical Pharmacology

    Background:

    • Glaucoma management often involves miotic agents.
    • Understanding the long-term effects of miotics like pilocarpine and echothiophate iodide is crucial for patient care.

    Purpose of the Study:

    • To evaluate the beneficial and harmful effects of pilocarpine and echothiophate iodide in open-angle glaucoma.
    • To compare uniocular miotic therapy with fellow eye controls.

    Main Methods:

    • Prospective study involving 59 primary open-angle glaucoma patients.
    • Uniocular treatment with 2% pilocarpine or 0.125% echothiophate iodide.
    • Fellow eye served as a control for each patient.

    Main Results:

    • Pilocarpine is cataractogenic, with changes less marked and slower than echothiophate iodide.

  • No significant difference in optic disc changes or glaucomatous field defects between treated and control eyes.
  • 11 optic disc changes and 10 glaucomatous field defects observed in the combined 118 eyes.

    • Conclusions:

    • Miotics, including pilocarpine alone, should be prescribed conservatively for glaucoma suspects.
    • Both pilocarpine and echothiophate iodide carry risks, particularly cataract formation.
    • Long-term miotic therapy requires careful monitoring for adverse effects.
