Eye oscilations with neurological implications in pediatric age

Area of Science:

• Neuroscience
• Ophthalmology
• Pediatrics

Background:

• Congenital eye oscillations, including nystagmic and non-nystagmic types, are observed from birth.
• Most cases present as infantile nystagmus within the first six months, encompassing idiopathic, sensory, and latent motor forms.
• Approximately 33% of ocular oscillations are linked to underlying neurological diseases or syndromes, necessitating prompt identification due to potential visual and vital complications.

Purpose of the Study:

• To systematically review literature on supranuclear gaze control mechanisms and ocular oscillations with neurological implications in children.
• To assess existing clinical-anatomical associations for these conditions.
• To propose a protocol for complementary diagnostic studies in pediatric cases of ocular oscillations.

Main Methods:

• Systematic literature review focusing on supranuclear gaze control and pediatric ocular oscillations.
• Analysis of existing clinical-anatomical associations.
• Development of a proposed protocol for diagnostic investigations.

Main Results:

• Certain anatomical pathways in supranuclear gaze control remain incompletely understood.
• Specific anatomical explanations for the pathogenesis of most ocular oscillations (except seesaw and upbeat nystagmus) were not identified.
• The importance of comprehensive neuro-ophthalmological examinations and additional testing for children with neurologically indicative ocular oscillations is evident.

Conclusions:

• Supranuclear gaze control involves a complex neurological network requiring further research.
• Enhanced understanding of this network may elucidate the specific presentations of ocular oscillations.
• Neuroimaging is frequently indicated, with other tests selected based on individual clinical presentation.
