Associated Conditions & Findings

Optic nerve hypoplasia

Optic nerve hypoplasia is underdevelopment of the optic nerve, which can affect vision.

In short: Optic nerve hypoplasia

  • It can be associated with basal encephaloceles.
  • It affects the nerve carrying vision to the brain.
  • Its effect on vision varies.
  • It is evaluated by eye specialists.

What it is

It is underdevelopment of the optic nerve, the nerve that carries visual information from the eye to the brain. Its effect on vision ranges from mild to significant.

Understanding Optic nerve hypoplasia

It can be associated with basal encephaloceles and midline brain conditions, and its effect on vision varies depending on the degree of underdevelopment. Because it involves the visual pathway, eye specialists assess it and monitor vision, and it may prompt evaluation for related midline findings.

Why it matters

Understanding optic nerve hypoplasia helps families see why basal encephaloceles warrant eye assessment and why this finding's effect on vision is individualized.

Common questions

What is optic nerve hypoplasia?

Underdevelopment of the optic nerve.

Which encephaloceles is it associated with?

Basal types and midline brain conditions.

Does it always cause significant vision loss?

No — its effect varies.

Bottom line

Optic nerve hypoplasia is underdevelopment of the optic nerve that can accompany basal encephaloceles and affect vision.
