    Advanced open-angle glaucoma significantly alters electroretinography (ERG) function. This study found numerous abnormal ERG parameters in glaucoma patients compared to healthy controls, highlighting ERG

    Area of Science:

    • Ophthalmology
    • Neuroscience
    • Medical Imaging

    Background:

    • Open-angle glaucoma is a leading cause of irreversible blindness.
    • Early detection and monitoring of glaucoma progression are crucial.
    • Electroretinography (ERG) assesses retinal function and may offer insights into glaucoma pathophysiology.

    Purpose of the Study:

    • To prospectively evaluate electroretinography (ERG) parameters in patients with advanced open-angle glaucoma.
    • To compare ERG results between glaucoma patients and age- and sex-matched healthy controls.
    • To identify specific ERG abnormalities associated with advanced open-angle glaucoma.

    Main Methods:

    • Prospective evaluation of 14 patients diagnosed with advanced open-angle glaucoma.
    • Standard electroretinography (ERG) testing was performed on all participants.

  • ERG results were compared to a control group of healthy individuals matched for age and sex.

    • Main Results:

    • Glaucoma patients exhibited significantly abnormal electroretinography (ERG) parameters compared to controls.
    • Specific ERG abnormalities were identified in patients with advanced open-angle glaucoma.
    • The findings indicate widespread retinal dysfunction in advanced glaucoma.

    Conclusions:

    • Electroretinography (ERG) is a sensitive tool for detecting functional deficits in advanced open-angle glaucoma.
    • ERG abnormalities correlate with the severity of open-angle glaucoma.
    • ERG may serve as a valuable biomarker for monitoring glaucoma progression and treatment efficacy.
