Optic atrophy in early childhood, associated with ataxia, spasticity, mental retardation, and posterior column sensory loss Behr syndrome has an autosomal recessive pattern of inheritance . Behr syndrome is characterized by the association of early-onset optic atrophy with spinocerebellar degeneration resulting in ataxia , pyramidal signs ...
Dominant optic atrophy was first described clinically by Batten in 1896 and named Kjer’s optic neuropathy in 1959 after Danish ophthalmologist Poul Kjer, who studied 19 families with the disease. [3] Although dominant optic atrophy is the most common autosomally inherited optic neuropathy (i.e., disease of the optic nerves), it is often ...
PEHO syndrome (progressive encephalopathy with edema, hypsarrhythmia and optic atrophy) is an autosomal recessive and dominant, progressive neurodegenerative disorder that starts in the first few weeks or months of life. Early symptoms include infantile spasms, hyparrhythmia, and seizures, and optic atrophy.
A slowly progressive optic neuropathy, dominant optic atrophy, usually presents in the first decade of life and is bilaterally symmetrical. Examination of these patients shows loss of visual acuity, temporal pallor of the optic discs, centrocecal scotomas with peripheral sparing, and subtle impairments in color vision.

The optic disc may appear mildly hyperemic with small splinter hemorrhages on or around the disc, or may appear nearly normal. Optic atrophy typically develops later and may appear mild. In later stages the optic atrophy can become severe, which indicates less opportunity for recovery. [3]
It is characterized by optic atrophy followed shortly by loss of hearing and peripheral neuropathy. Onset of the disease occurred in early childhood, as opposed to the later onset of similar diseases. Optic atrophy occurs in the first year and the following symptoms show up before thirteen years.

Usually, individuals with this condition have cerebellar ataxia, areflexia, high-arched feet, optic nerve wasting/degeneration, sensorineural deafness. [5]These symptoms have variable onset, but they generally begin episodically after having a fever-causing infection such as the common cold, manifesting mainly as sudden-onset ataxic episodes and encephalopathy.
