    Area of Science:

    • Ophthalmology
    • Neuroscience
    • Developmental Biology

    Background:

    • Optic nerve hypoplasia (ONH) is an increasingly recognized congenital anomaly.
    • It is characterized by a spectrum of clinical presentations, often involving visual deficits.

    Observation:

    • Key diagnostic indicators include a small optic disc and potential visual impairment.
    • Associated signs may include a Marcus Gunn pupil, double peripapillary ring, and a thin retinal nerve fiber layer.

    Findings:

    • The study highlights the diverse presentations of optic nerve hypoplasia.
    • Bilateral ONH can suggest underlying midline brain developmental abnormalities.

    Implications:

    • Recognizing ONH variability is essential for accurate diagnosis and management.
    • Investigating unexplained vision decrease is critical, especially when ONH is suspected.
