Horizontal Gaze Palsy with Progressive Scoliosis: A Case Report and Literature Review

Study on the relationship between scoliosis and vision problems: A narrative review

Adolescent scoliosis is one of the most common surgical disorders of the pediatric spine. With timely detection and early treatment, most scoliotic children can avoid major and expensive surgery. Vision problems are also frequently found at an early age and can take a toll on individuals quality of life. However, scoliosis, a severe health hazard to adolescents, is often accompanied by vision problems clinically, including myopia, astigmatism, strabismus, amblyopia, horizontal paralysis, and blindness. And people with genetic defects have a higher probability of suffering both spinal problems and vision problems than those with nongenetic defects. However, many individuals viewed scoliosis and vision problems as 2 irrelevant diseases. This review searched PubMed, China National Knowledge Infrastructure, and Web of Science for studies on adolescent, scoliosis, eye diseases, myopia, strabismus, spinal disorders, and vision problems for almost 3 decades, and thus confirmed the potential relationship between adolescent scoliosis and vision problems.

Visual and Vestibular Impairment and Idiopathic Scoliosis – are They Related?

Scoliosis is a tri-dimensional lateral curvature of the spine of 10° or more, with a rotational component. The most common form of scoliosis in the population is adolescent idiopathic scoliosis (AIS). As its name states, it has no known direct cause, even if, over time some evidence for multiple linked causes has been provided

There is some evidence accumulated pointing to an association between AIS and posture control, where vision and vestibular systems are both involved

We analysed the links between the curvature of the spine, its evolution and possible visual and vestibular impairment on 44 children with scoliosis.

A postural aetiology of scoliosis in the visually and vestibular impaired population could be implied, since all the cases that could be defined as scoliosis and not as a scoliotic attitude (Cobb > 10º) were positive for the Fukuda Stepping Test and more than 60% of the patients that had a Cobb angle value higher than 15º had a type of visual impairment (myopia).

Imaging of congenital cranial dysinnervation disorders: What radiologist wants to know?

We aim to review the imaging features of congenital cranial dysinnervation disorders. Characteristic imaging findings can define subtypes of these disorders through assessment of cranial nerves, extraocular muscles, orbital, and brain abnormalities. Duane retraction syndrome shows absent or hypoplasic 6th cranial nerve and preserved extraocular muscles (EOM). Mobius syndrome shows absent 7th and 6th cranial nerves, absence of facial colliculus, flattening of the dorsal aspect of the pons, hypoplasia of the pons and medulla, and flattening of the 4th ventricular floor. Congenital fibrosis of the extraocular muscles reveals unilateral or bilateral hypoplasia or aplasia of the 3rd cranial nerve, atrophy of superior rectus and levator palpebrae superioris muscles, and atrophy of the brainstem and cerebellar hemispheres. Horizontal gaze palsy and progressive scoliosis show characteristic split pons sign, butterfly medulla, absent facial colliculi, and spinal scoliosis. HOXA1 Mutations show a bilateral absence of 6th cranial nerves with the underdeveloped inner ear. Pontine Cap Tegmental Dysplasia shows ventral pontine hypoplasia, dorsal tegmental projection into the 4th ventricle, and variable cranial nerve deficits.
