Can Scoliosis Affect Eyesight? What the Research Shows About Vision, Balance, and Spinal Curves

By Dr. Justin Dick, DC · Clear Life Scoliosis and Chiropractic Center, Charlotte, NC · Published October 14, 2026

No published evidence I have found shows that scoliosis damages eyesight. A curved spine does not change visual acuity, cause nearsightedness, or harm the eye. The research that does exist runs in a different direction: it asks whether visual and balance systems are involved in how some curves develop, and it finds associations in specific groups without establishing cause.

I am Dr. Justin Dick, and parents at Clear Life Scoliosis and Chiropractic Center in Charlotte, NC ask this question more often than you might expect, usually because they read online that scoliosis causes vision problems. This post separates what is supported from what is not.

Refractive Error: No Association in a Large School Sample

Cai and colleagues screened school-aged students in Nantong, China, and found a scoliosis prevalence of 2.2 percent. In multivariable analysis, myopia, hyperopia, astigmatism, and anisometropia (unequal prescriptions between the eyes) were not associated with scoliosis. Lower body mass index, rural residence, and older age were. That is a cross-sectional study, so it cannot test whether one condition causes the other, but it gives no support to the idea that common refractive errors and scoliosis are linked.

Strabismus: A Higher-Risk Group

Strabismus, a misalignment of the eyes, is where the association shows up. Zhuang and colleagues studied 561 patients aged 10 to 35 who were candidates for strabismus surgery and found radiographic scoliosis (Cobb angle of 10° or more) in 19.6 percent. Within that group, scoliosis was associated with female sex and lower body mass index, and not with anisometropia. The authors describe strabismus patients as a population at substantially elevated scoliosis risk.

Two cautions. First, 19.6 percent in a surgical strabismus population cannot be compared directly with the 2.2 percent from the Chinese school screening, because the age range, setting, and methods differ. Second, an association in either direction does not mean the eyes bent the spine or the spine misaligned the eyes. A shared neurological or developmental factor is at least as plausible.

Small Studies Linking Vision to Curve Pattern

Manac and colleagues reviewed 73 children with double major idiopathic scoliosis and compared those with visual disturbances to those without. The children with visual disturbances had a higher thoracic apex and larger thoracic Cobb angles, along with lower serum calcium and magnesium. This is a small retrospective study from one center, and the authors state that causal relationships cannot be established. I treat it as a hypothesis, not a finding to act on.

Vision, Balance, and Postural Control

The more defensible connection is through postural control. Standing balance depends on input from the eyes, the inner ear, and proprioceptors in the joints and muscles. Studies of adolescents with idiopathic scoliosis have repeatedly examined balance with eyes open and eyes closed. Osuka and colleagues, for example, tested 33 patients with thoracic curves on a force plate and found that postural stability with eyes closed was better two years after surgical correction than before. That does not tell us scoliosis affects vision. It tells us that how the body uses visual and non-visual information to stay upright is part of the scoliosis picture.

This is the territory of my own research on the labyrinthine righting reflex, the reflex that keeps the head level relative to gravity. It is a vestibular and postural reflex, not a vision test, and I describe it that way to patients.

Head Tilt That Looks Like a Spinal Problem

There is one practical crossover worth knowing. Some eye conditions produce a compensatory head tilt, and a persistent head tilt can be mistaken for a neck or upper back asymmetry. When a child has a head tilt with no structural curve on imaging, an eye examination belongs on the list. The reverse also happens: a structural cervicothoracic curve can produce a head tilt that has nothing to do with the eyes. My post on postural versus structural curves covers how imaging separates the two.

Vision Loss After Scoliosis Surgery

Families sometimes find reports of vision loss connected to scoliosis. Those reports concern surgery, not the curve. Barros and colleagues described 3 cases of postoperative visual deficit among 849 scoliosis correction surgeries, with prolonged operative time, blood loss, and prone positioning among the proposed contributors. Two of the three patients recovered fully. It is a rare complication and is part of surgical informed consent.

How Dr. Justin Dick Handles Vision Questions at Clear Life

At our Charlotte office, a scoliosis examination includes head position, balance testing, and a history that asks about vision problems, strabismus, and prior eye care. When something points to the eyes, I refer to an optometrist or ophthalmologist. I do not attribute visual symptoms to a spinal curve. Our pages on curve patterns and cervical alignment and scoliosis cover the head and neck side of the exam.

Research and Evidence

Evidence tiering: every vision study cited here is observational and most are cross-sectional. None can establish direction or cause. The strabismus association is the most consistent signal, and it is still an association.

My own work in this area is the labyrinthine righting reflex case report, Reduction of Adolescent Idiopathic Scoliosis Utilizing the Labyrinthine Righting Reflex: A Case Report (Cureus, 2026, PMID 41685001), which describes a mild curve treated with a protocol that included reflexive engagement of the head-righting system. It is a single case and does not address vision. The cervical mechanics study, A Retrospective Cross-Sectional Analysis of Abnormal Cervical Mechanics in Patients With Scoliosis (Cureus, 2025, PMID 41018459), documents cervical alignment changes in 37 patients with scoliosis, which is relevant because head and neck position is where visual and vestibular inputs meet the spine.
