    Preoperative electroretinogram (ERG) reliably predicts visual outcomes after vitrectomy for dense vitreal opacities. Higher ERG b-wave amplitudes correlate with better postoperative vision, aiding surgical planning.

    Area of Science:

    • Ophthalmology
    • Retinal Diseases
    • Diagnostic Imaging

    Context:

    • Dense vitreal opacities obscure fundus visualization, complicating diagnosis and prognosis.
    • Vitrectomy is a surgical intervention to clear the vitreous humor.
    • Preoperative visual acuity in affected patients ranges from light perception to 0.1.

    Purpose:

    • To investigate the predictive value of preoperative electroretinogram (ERG) amplitudes for visual outcomes following vitrectomy.
    • To establish a correlation between ERG b-wave amplitudes and postoperative visual acuity in patients with vitreal opacities.

    Summary:

    • Vitrectomy was performed on 17 patients (19 eyes) with dense vitreal opacity.
    • A statistically significant positive correlation was found between preoperative scotopic ERG b-wave amplitude and postoperative visual acuity (r=0.7709, p<0.01).

  • Similarly, a positive correlation was observed between preoperative photopic ERG b-wave amplitude and postoperative visual acuity (r=0.8086, p<0.01).

    • Impact:

    • Preoperative ERG measurements can predict the degree of visual improvement after vitrectomy.
    • This predictive capability assists in managing patient expectations and optimizing surgical strategies for various ocular diseases causing vitreal opacities.
    • ERG serves as a valuable tool for assessing retinal function and forecasting visual prognosis in challenging cases.
