    This study introduces an objective method using visual evoked potentials (VEP) to measure retinal visual acuity. The VEP method demonstrated high accuracy when compared to subjective visual acuity measurements.

    Area of Science:

    • Ophthalmology
    • Neuroscience
    • Vision Science

    Background:

    • Accurate measurement of retinal visual acuity is crucial for diagnosing and managing vision disorders.
    • Subjective visual acuity tests can be influenced by patient cooperation and effort.
    • Objective methods are needed to complement subjective assessments.

    Purpose of the Study:

    • To evaluate an objective method for determining retinal visual acuity using visual evoked potentials (VEP).
    • To compare the accuracy of the objective VEP method with subjective visual acuity measurements.

    Main Methods:

    • Sixty subjects with varying subjective visual acuity (20/25 to 20/12) were tested.
    • A computer-controlled laser interferometer generated pattern-reversal stimuli using interference fringes.

  • Steady-state VEPs were recorded at different spatial frequencies and analyzed using Fourier analysis and linear regression.
  • Objective retinal acuity was calculated by intersecting the regression line with the spatial frequency axis.

    • Main Results:

    • The objective VEP method showed a high degree of agreement with subjective visual acuity.
    • In 68% of cases, the difference between objective and subjective acuity was within +/- 5.1 cycles per degree (c/d).
    • In 86% of cases, the difference was within +/- 7.7 c/d.

    Conclusions:

    • Objective VEP measurement provides a reliable and accurate alternative to subjective visual acuity testing.
    • This VEP method can be a valuable tool in clinical ophthalmology and vision research.
    • The findings support the use of VEP for objective assessment of visual function.
