Horizontal Gaze Palsy with Progressive Scoliosis: Causes, Symptoms, and Treatment
Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 2, 2026.
What kind of doctor treats Horizontal Gaze Palsy with Progressive Scoliosis?
An orthopedic surgeon usually treats the spine problems, often one who focuses on children's spines. An ophthalmologist helps confirm the eye findings, and a genetic specialist can confirm the diagnosis and discuss family risk. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Horizontal Gaze Palsy with Progressive Scoliosis?
Horizontal gaze palsy with progressive scoliosis is a rare genetic condition that changes the way the eyes move from side to side and causes the spine to curve as a child grows. It is present from birth.
Horizontal gaze palsy means trouble moving both eyes together to look left or right; progressive scoliosis means the spine curves sideways and worsens over time. People with this condition can usually still look up and down, and often turn their head to look sideways.
Symptoms
The eye problem is usually noticed in infancy, when a baby cannot make quick side-to-side eye movements. The spinal curve often appears in childhood and can worsen during the teenage growth spurt. Hearing and thinking are not affected.
Causes and who gets it
Changes in a gene called ROBO3 cause the condition by guiding nerve wiring in the brainstem before birth. It is passed down in an autosomal recessive pattern, meaning a child must get one changed copy from each parent; carrier parents usually have no symptoms.
How doctors diagnose it
A doctor will ask about family history and check how the eyes move. An eye doctor may rule out other causes of limited movement. X-rays show whether the spine is curved and how large the curve is. Genetic testing can confirm the diagnosis.
Treatment
There is no treatment that fixes the eye movement problem itself, and most people adapt so well with head turns that daily life is not greatly affected. The spinal curve is treated like other scoliosis: mild curves are watched with regular X-rays, moderate curves may need a brace, and severe curves may need surgery, depending on the curve's size and the child's remaining growth.
When to see a doctor
See a doctor if a child cannot follow objects from side to side, often turns the head to look at things, or shows an uneven spine, such as one shoulder sitting higher than the other. Curves can worsen quickly during growth spurts.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either one can be a steady home base, watching growth, ordering X-rays, and coordinating referrals to specialists.
Common questions
Does this condition affect intelligence?
No. Thinking, learning, and memory are not affected. People with this condition learn and work normally.
Can the eye movement problem be fixed with surgery?
No. The problem comes from the way nerves are wired in the brainstem. Eye muscle surgery does not restore side-to-side movements. Most people adapt well by turning their head.
Will the spine curve always need surgery?
Not always. Small curves may only need watching, and some curves are managed with a brace. Surgery is usually considered for large curves or curves that keep getting worse.
Can my other children have this condition?
It is possible if both parents carry the changed gene. A genetic counselor can explain the chances and offer testing for family members.
