Overview

Ocular anomalies-axonal neuropathy-developmental delay syndrome is a very rare genetic condition that affects several parts of the body at the same time, including the eyes, the nervous system, and brain development. The name describes the three main areas it impacts: problems with the eyes (ocular anomalies), damage to the long fibers of nerve cells that carry signals through the body (axonal neuropathy), and slower-than-typical development of skills like talking, walking, and learning (developmental delay). People with this condition may be born with or develop eye problems such as unusual eye structure or reduced vision. The nerve damage can cause muscle weakness, reduced reflexes, and difficulty with coordination. Developmental delays can range from mild to more significant, affecting both physical and intellectual milestones. Because this syndrome is extremely rare and was only recently described, our understanding of it is still growing. There is currently no cure. Treatment focuses on managing symptoms, supporting development through therapies, and monitoring for complications. A team of specialists — including eye doctors, neurologists, and developmental pediatricians — typically works together to care for affected individuals.

Also known as:

Key symptoms:

Eye abnormalities present from birth or early childhoodReduced vision or visual impairmentMuscle weakness, especially in the arms and legsDecreased or absent reflexesDifficulty with coordination and balanceDelayed milestones such as sitting, walking, or talkingIntellectual disability or learning difficultiesAbnormal nerve conduction (nerves do not send signals properly)Low muscle tone (floppiness in infancy)Possible abnormalities seen on brain imaging
