    Patients with optic neuritis experience reduced contrast perception at higher spatial frequencies, but this improves with recovery. Despite subjective normal vision, underlying contrast sensitivity deficits may persist.

    Area of Science:

    • Ophthalmology
    • Neuroscience
    • Visual Perception

    Background:

    • Optic neuritis causes visual disturbances, impacting contrast perception.
    • Contrast sensitivity and suprathreshold contrast perception are key visual functions.
    • Understanding these deficits aids in assessing visual recovery after optic neuritis.

    Purpose of the Study:

    • To compare subjective suprathreshold contrast perception with objective threshold contrast sensitivity in acute optic neuritis.
    • To investigate the recovery patterns of contrast perception during the healing phase.
    • To determine if subjective visual normality correlates with objective visual function recovery.

    Main Methods:

    • Subjective suprathreshold contrast matching technique was employed.

  • Contrast sensitivity was measured using threshold-based methods.
  • Assessments were conducted repeatedly during the recovery phase in patients with unilateral optic neuritis.

    • Main Results:

    • Suprathreshold contrast perception was attenuated at high and intermediate spatial frequencies.
    • Low spatial frequencies showed spared suprathreshold contrast vision, unlike threshold sensitivity.
    • Recovery led to normalized suprathreshold contrast perception and subjective visual normality, despite persistent threshold abnormalities.

    Conclusions:

    • Optic neuritis affects suprathreshold contrast perception in a frequency-dependent manner.
    • Subjective visual normality can be achieved before full recovery of contrast sensitivity.
    • Suprathreshold contrast perception may be a more resilient visual function during optic neuritis recovery.
