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 ...

Optic neuropathy is damage to the optic nerve from any cause. The optic nerve is a bundle of millions of fibers in the retina that sends visual signals to the brain. Damage and death of these nerve cells, or neurons, leads to characteristic features of optic neuropathy.
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 ...

Costeff syndrome, or 3-methylglutaconic aciduria type III, is a genetic disorder caused by mutations in the OPA3 gene. [1] It is typically associated with the onset of visual deterioration (optic atrophy) in early childhood followed by the development of movement problems and motor disability in later childhood, occasionally along with mild cases of cognitive deficiency. [2]
Behr specialized in the study of neuro-ophthalmological disorders, making contributions in his research involving the pathological processes in papilloedema and tabetic optic atrophy. His name is lent to "Behr's pupil", a slightly dilated pupil in association with an optic tract lesion that is usually associated with a contralateral hemiparesis .
