Understanding ocular torticollis in children.

Area of Science:

• Ophthalmology
• Pediatric Pathology
• Neurology

Background:

• Abnormal head posture (AHP), or torticollis, is a common sign in pediatric patients, with an incidence of 5.6% in ophthalmology and 3.19% in pediatric ophthalmology.
• AHP is adopted to enhance vision, maintain binocular single vision, center visual fields, or for cosmetic reasons.
• Face turn is the most frequent AHP in pediatric ophthalmology, often associated with Duane syndrome, congenital fibrosis, nystagmus, refractive errors, or visual field defects.

Purpose of the Study:

• To highlight the significance of ocular causes of abnormal head posture in children.
• To emphasize the need for ophthalmological evaluation in all children presenting with AHP.
• To underscore the importance of interdisciplinary collaboration in diagnosing the etiology of AHP.

Main Methods:

• Review of common ocular diseases causing various types of abnormal head posture (face turn, head tilt, chin-up/down).
• Discussion of diagnostic challenges posed by compensatory head postures.
• Emphasis on the role of ophthalmologists in identifying primary ocular etiologies.

Main Results:

• Common causes of face turn include Duane syndrome, congenital fibrosis, nystagmus, refractive errors, and visual field defects.
• Frequent causes of head tilt in children are congenital nystagmus, superior oblique paresis, dissociated vertical deviation, Brown syndrome, and refractive errors.
• Chin-up/down postures are often linked to "A" and "V"-pattern strabismus, ptosis, nystagmus, and refractive errors.

Conclusions:

• Torticollis is a sign, not a diagnosis, indicating an underlying condition, frequently ocular.
• While some ocular causes of AHP are easily diagnosed, others like superior oblique paralysis or Duane syndrome can be confused with congenital AHP.
• Mandatory interdisciplinary collaboration among ophthalmologists, pediatricians, surgeons, ENTs, and neurologists is essential for accurate AHP etiology determination.
