    Area of Science:

    • Ophthalmology
    • Medical technology
    • Visual science

    Background:

    • Metamorphopsia causes symptomatic visual distortion.
    • Accurate quantification of visual distortion is clinically important.
    • Current methods for assessing metamorphopsia may have limitations.

    Purpose of the Study:

    • To evaluate a novel digital method for quantifying metamorphopsia.
    • To assess the correlation between the new digital method and M-CHARTS scores.
    • To determine the viability of digital line distortion for spatial characterization of visual distortions.

    Main Methods:

    • A prospective, cross-sectional observational study was conducted.
    • Subjects digitally altered a straight dotted line to appear straight.
    • The manipulated area under the curve (M-AUC) was calculated to quantify distortion.

    Main Results:

    • Sixty-two percent of test targets were straightened by subjects.
    • The M-AUC showed significant correlation with M-CHARTS scores horizontally (P < .001) and vertically (P = .05).
    • The digital method demonstrated effectiveness in quantifying visual distortion.

    Conclusions:

    • Digital alteration of a straight line may quantify metamorphopsia.
    • This method offers a potential way to spatially characterize visual distortions.
    • The digital method shows promise as a viable tool in ophthalmology.
