Strabismus may be linked to sensory processing disorder (SPD). This case suggests eye alignment issues could stem from sensory imbalances, proposing a new
Area of Science:
- Neuroscience
- Ophthalmology
- Developmental Pediatrics
Background:
- The link between Sensory Processing Disorder (SPD) and strabismus remains under-investigated.
- Traditional strabismus diagnosis often overlooks sensory modulation's role in visual behavior.
Observation:
- A pediatric case presented with episodic monocular eye closure triggered by environmental stimuli.
- Symptoms aligned with sensory over-responsivity (SOR), a subtype of SPD, without other pathology.
Findings:
- Proposes the 'Fusion Dysregulation Hypothesis': strabismus subtypes (esotropia/exotropia) may reflect sensory connectivity extremes.
- Sensory hyperresponsivity (esotropia) may involve overconnectivity; hypoconnectivity (exotropia) linked to conditions like autism spectrum disorder.
Implications:
- Highlights the need for interdisciplinary assessment of strabismus and SPD.
- Advocates for sensory profiling in strabismus and ophthalmologic evaluation in SPD.
- Suggests sensory modulation plays a role in pediatric strabismus, supporting bidirectional screening.

These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
